一家国内货代公司去年第四季度按惯例把一批锂电池移动电源发到了沙特，走的承运航司是过往合作多年的某中东航司。AWB、DGD、SHC 全部按 IATA DGR 标准填写，UN 38.3 测试摘要齐全，外箱标贴规范。结果货到沙特利雅得机场——被海关全部扣留。 调查结果让所有人头疼：沙特刚刚更新了 SV（State Variation），对某类锂电池增加了额外的入境申报要求。货代用的是去年的合规模板，没查新版 SV，直接撞枪口上。整批货退运 + 海关罚款 + 客户索赔 + 三个月解决周期。 这种事每年都在跨境物流圈反复上演。原因都指向同一个雷区：用了去年的规则发今年的货。这一篇我们把 OV（Operator Variation）和 SV（State Variation）一次性拆给你看，让你避开 90% 的"昨天还能走、今天就被退"的坑。
一、OV 和 SV 是什么：IATA DGR 的"补丁系统"
IATA DGR 主体规则是全球通用的。但全球航司和国家各有不同的安全考量、法律环境、应急能力，所以 IATA 在第 2 章「Limitations」里专门设了两套"补丁系统"：
| 简称 | 全称 | 谁出的 | 约束谁 |
|---|
| OV | Operator Variation | 承运航司 | 该航司承运的所有 DG 货 |
| SV | State Variation | 国家民航当局 | 该国境内（起降、过境）的所有 DG 货 |
核心理解：
- IATA DGR 主表给的是最低门槛
- OV 和 SV 给的是更严的本地规则
- 谁严按谁来：OV 比 SV 严，按 OV；SV 比 OV 严，按 SV
- 永远不能用"主表说可以"对抗"OV/SV 说不行"
二、SV 和 OV 在 IATA DGR 手册里长什么样
打开任意一版 IATA DGR，第 2.8 章和 2.9 章分别列了：
- 2.8 State Variations：按国家三字代码排序（如 USG 美国、CHG 中国、AEG 阿联酋、DEG 德国）
- 2.9 Operator Variations：按航司二字代码排序（如 CA 国航、LH 汉莎、EK 阿联酋、BA 英航）
每条 SV 或 OV 都有一个唯一编号，格式形如：
- SV：
USG-01、CHG-04、AEG-02 - OV：
CA-01、LH-08、EK-12
编号后面是这条变更的具体内容——可能是禁运某类、加严某类、要求额外文件、限制某机型等。
三、SV 高频内容：5 大类常见变更
每个国家的 SV 内容不同，但常见的几类变更模式是相似的：
1. 禁运 / 限制特定 UN 号
例：某国 SV 规定 UN3480（单独运输的锂离子电池）在客机上完全禁运。
2. 加严特定 Class 的包装 / 数量
例：某国 SV 要求 Class 6.1 毒性物质单件净量低于 IATA 主表的限值。
3. 要求额外申报 / 进口许可
例：某国 SV 要求所有 Class 2 气体货物在入境前 72 小时提交进口许可证号。
4. 限制特定机型 / 航线 / 时段
例：某国 SV 规定某些 DG 不允许在夜航中运输；或不允许通过特定军用 / 民用混合机场。
5. 应急联络要求
例：某国 SV 要求 24h 应急电话必须是该国境内本地号码，不能是境外号码。
四、OV 高频内容：8 类常见变更
每家航司的 OV 内容差异更大，下面是 8 类常见 OV 模式：
1. 完全禁运某些 Class 或 UN 号
例：某航司可能在 OV 里写"完全不接受 Class 1 爆炸品"或"完全不接受 Class 5.2 有机过氧化物"。
2. 加严锂电池规则
锂电池是 OV 改版最频繁的领域。许多航司 OV 比 IATA 主表更严，例如：
- 禁运 Section IA 货
- 禁运超 100 Wh 的纯电池
- 禁运报废 / 召回锂电池（多数航司）
- 平衡车 / 电动滑板车整车禁运
3. 限制单 AWB / 单 ULD / 单航班总量
例：某航司 OV 规定单 ULD 内锂电池总瓦时不超过某阈值。
4. 要求额外的 24h 应急服务
例：某航司要求托运人提供该航司认可名单内的应急服务商电话。
5. 要求电子化 DG 申报
例：某航司只接受 e-DGD 不接受手写 DGD。
6. 加严标贴和包装
例：某航司要求某些 Class 货物必须使用特定供应商的 UN 规范包装。
7. 限制中转机场
例：某航司禁止某些 Class 货物在其网络的特定枢纽中转。
8. 提前申报窗口
例：某航司要求 DG 货必须在航班起飞前 48 小时提交完整 DGD。提前申报窗口往往和航司内部安检 / 复核能力挂钩，节假日或人手紧张期，提前窗口可能从 48 小时拉长到 72 小时。这种季节性变化也属于 OV 的实操范畴，需要持续关注。
五、如何系统性地查 OV 和 SV
实操中查 OV / SV 是 DG 派工流程的必备一步。下面是完整查询流程：
Step 1：列出整条运输链上的所有"节点"
- 起运国
- 所有过境国（含中转停留）
- 目的国
- 起运承运航司
- 任何中转承运航司
Step 2：逐个节点查 SV / OV
- 国家：查 IATA DGR 2.8 章 SV
- 航司：查 IATA DGR 2.9 章 OV
Step 3：交叉对比与主表的差异
- 主表说允许，OV / SV 说禁运 → 按 OV / SV 走（不能走）
- 主表说允许 5 L / 件，OV / SV 说 2 L / 件 → 按 OV / SV 走（更严）
- 主表要求标准 DGD，OV 要求 e-DGD → 按 OV 走
Step 4：留档备查
- 每票货的 SV / OV 查询记录留档至少 2 年
- 一旦被海关 / 航司事后追溯，能拿出当时的查询记录证明合规尽职
- 留档内容包括：查询日期、所查 SV / OV 编号、查询人、结论、是否影响发货
可以用 OneCargoKit 的 Dangerous Goods Check 在派工前快速对照 OV / SV 的高频禁运项，工具内置常见承运航司的 OV 提示。但 OV / SV 完整查询仍然以 现行版 IATA DGR 第 2 章 为权威来源——工具是预筛，手册才是最终依据。
六、跨境物流团队最容易"用了去年的规则"的 5 个场景
OV / SV 改版几乎是每年都有，部分高敏感品类（特别是锂电池）甚至一年改几次。下面这 5 个场景是用了过时规则最容易翻车的地方：
1. 锂电池 OV 改版
锂电池 PI 965-970 几乎每隔一两年就有更新。Section II 的瓦时阈值、单件电池数量限制、操作标签规格都可能微调。新人最容易掉的坑就是"我去年发过这票货，今年照着做"。
2. 沙特、阿联酋、印度等高变更国 SV
中东、南亚国家的 SV 更新频率高于欧美。沙特特别是这两年加严了大量与海关 / 安检相关的 SV，许多老路线"突然走不通了"。
3. 新冠后医药冷链 SV
各国对疫苗、医疗样本、生物制品的 SV 在 2020 年后大幅更新。冷链货代要特别关注 UN3373、UN2814 相关 SV。
4. 平衡车 / 电动车类 OV
电动平衡车、电动自行车这类含锂电池的整车产品，几乎所有主流航司在过去 3-5 年都加严或禁运。早期能走的航司现在不一定还能走。
5. 中转枢纽 OV
迪拜、新加坡、香港、法兰克福这些中转大枢纽，对中转 DG 货的 OV 经常调整。一条航线的中转节点变了，整票货合规口径就要重做。
七、SV / OV 与货代日常工作的"嵌入点"
OV / SV 不是一个孤立的"查询动作"，它需要嵌入货代日常工作流的多个环节。理解嵌入点能让合规变成自动化的肌肉记忆，而不是每次都靠人工提醒：
1. 客户询价阶段嵌入
客户发来询价时，第一步不是算运费，而是问清楚 UN 号 / 品类 / 起运地 / 目的地 / 时效。拿到这五项后，立刻在心里过一遍最新的 OV / SV——能不能走、有没有禁运、有没有额外要求。如果起运承运航司有 OV 禁运这类货，应该在询价阶段直接告诉客户"建议换 X 航司"或"走海运段"，而不是接单后才发现走不了。
2. 报价单嵌入
DG 货报价单上要明确标注"基于 X 航司 X 月份的现行 OV"，并写明若 OV / SV 在出货前发生变更，报价可能调整。这一行字看起来啰嗦，但能在客户中途质疑加价时提供合同依据。
3. 订舱阶段嵌入
提交订舱前再查一次 OV——许多航司 OV 是月度更新的，从报价到订舱可能间隔几天。订舱系统的自动拒单往往就是 OV 加严了你没注意到。
4. 出 DGD 阶段嵌入
DGD 草稿出完，签字前再过一次 OV / SV——确认所有字段（应急电话、Aircraft Type、Authorization、Special Provisions）都符合现行 OV / SV 要求。
5. 起运前 24 小时嵌入
起运前一天再核对一次 SV / OV，特别是有政治、地缘、天灾等非常规事件时（如某国突发空域管制、某航司紧急停飞）。
把这 5 个嵌入点写进公司内部 SOP 文件，新人按 SOP 跑，老员工形成习惯，整个团队的 OV / SV 出错率会明显下降。
八、SV 和 OV 冲突时怎么办
实操中经常出现"SV 允许、OV 禁运"或反过来的情况，处理原则：
- 永远以更严的为准
- OV 不能比 SV 更宽松（航司不能"豁免"国家规定）
- SV 不能比 ICAO TI 更宽松（国家不能"豁免"国际公约）
- DG 主表是底线，OV / SV 只能加严不能放宽
举例：
- IATA 主表说某 UN 号客机限重 5L
- 某国 SV 说限重 2L
- 某航司 OV 说该 UN 号完全禁运
- 结论：按 OV 走，完全不能走
派工时把这套"由严到宽"的排序拉一下，整票货能不能走就清楚了。
实操技巧：把每票货的 OV / SV 复核结果做成一张内部"路线评估表"，包括起运国 SV、目的国 SV、过境国 SV、起运承运航司 OV、中转承运航司 OV 这 5 列，每列要么标"OK"要么标具体限制内容。这张表存档备查，一旦后续出事，能够证明你已尽到合规调查义务。这种留档习惯不仅对内审计有用，对接保险、应对海关追责时也是关键证据。许多大型 DG 货代公司把这张表当作 DGD 的"姊妹文件"管理。
九、OV / SV 查询频率建议
| 角色 | 推荐查询频率 |
|---|
| 货代 / 操作 | 每月至少一次系统性更新自己的 OV / SV 速查表 |
| 跨境电商运营 | 每季度对所发品类的 OV / SV 重新核对 |
| 工厂出口 | 至少每半年和货代对账一次 |
| 大型托运人 | 每周关注新一版 IATA Cargo Operations Bulletin 通报 |
许多公司还会订阅 IATA 官方的 Dangerous Goods Subscription，每月推送 SV / OV 增量更新——对常发 DG 货的团队非常值得。
十、常见误区
- 误区 1：IATA DGR 主表过了，就一定能走 —— 错。OV / SV 可能禁运。
- 误区 2：去年走过的路线今年一样 —— 错。OV / SV 每年都改。
- 误区 3：航司没告诉我 OV 变更就是没变 —— 错。OV 变更航司不会一一通知货代，要主动查。
- 误区 4：SV 只是建议性的 —— 错。SV 是国家法律强制力的，违反可能被海关扣押 + 罚款。
- 误区 5：起运国 SV 过了，目的国 SV 不用管 —— 错。整条运输链所有节点的 SV 都要过。
- 误区 6：OV 不公开查询 —— 错。所有 OV 都在 IATA DGR 第 2.9 章里公开，订阅 IATA 数据库即可。
- 误区 7：经过的航空管制区 SV 不用查 —— 半对。如果只是飞越不停留通常不查，但任何起降 / 装卸的国家都要查。
- 误区 8：包机不用查 OV —— 错。包机也是航司运营，仍按 OV 走。
- 误区 9：SV / OV 的语言版本以英文为准 —— 是的，但有些国家会同时发布本地语言版本，两者冲突时以 IATA 英文版为准。
- 误区 10：用 AI 工具查询的 OV / SV 信息是权威的 —— 错。AI 训练数据可能滞后，OV / SV 必须以现行 IATA DGR 手册为准。
十一、实操检查清单：起运前 OV / SV 复核
- [ ] 起运国 SV 已查
- [ ] 所有过境国 SV 已查
- [ ] 目的国 SV 已查
- [ ] 起运承运航司 OV 已查
- [ ] 中转承运航司 OV 已查（如有）
- [ ] 锂电池 OV 已专门核对（这是高变更项）
- [ ] OV / SV 编号已记录在派工档案
- [ ] 任何"主表允许、OV/SV 禁运"已识别
- [ ] 24h 应急电话符合 SV 本地化要求
- [ ] 应急服务商在航司认可名单内（若 OV 要求）
- [ ] DG 申报截止时间符合 OV 要求
派工时把 OV / SV 复核作为 SOP 的最后一步硬卡口，能避免 99% 的"昨天还能走、今天就被退"的事故。配合 Surcharge Estimator 在报价阶段就把 OV / SV 可能的额外申报费、加严包装费、应急服务费计算进去，避免后期账单冲突。
十二、给三类岗位的判定方法
| 岗位 | OV / SV 核心动作 | 输出 |
|---|
| 货代 / 操作 | 每月更新 OV / SV 速查表 + 每票货起运前复核 | 合规走货方案 |
| 跨境电商运营 | 季度对所发品类 OV / SV 重检 | 物流方案调整 |
| 公司合规岗 | 订阅 IATA 数据库 + 每月通报内部 | 团队合规水位 |
跨境电商团队如果出口锂电池、化妆品喷雾、医药冷链这种 OV / SV 高变更品类，强烈建议设置专门的"合规变更跟踪岗"，即使只是兼职。这个岗位的产出体现在"事故没发生"——很难量化，但一次出事的代价远高于这个岗位的年薪。
十三、合规与边界提醒
- 本文是基于公开的 IATA DGR 第 2 章 Limitations 体系做的实操梳理，不构成法律、合规或安全建议
- 具体 OV / SV 内容随版本更新，以现行版 IATA DGR 第 2.8、2.9 章为准
- 国家民航当局可能在年中发布临时 SV（特别是 COVID、地缘冲突等情境下），起运前要查最新通报
- 航司 OV 变更可能不定期发布，特别关注公告板和订单系统提示
- 锂电池、平衡车、电动车类 OV 是当前变更最频繁的领域，建议每月专项更新
- 涉及军用机场、限制区域、敏感品类的 SV 建议委托具备国际货运专业资质的代理处理
十四、结尾：OV / SV 是 DG 链路里"时间最敏感"的合规
DG 链路里大部分规则相对稳定——9 大类不变、UN 号不变、PI 数字编号不变。但 OV 和 SV 每年都在改。地缘政治、新事件、新事故、新技术，任何一项都可能催生新的 SV / OV。比如某次空难调查结论里发现某类货物存在隐患，往往会催生新一轮的 SV / OV 集体加严；某条主流航线突然出现安检失误，承运航司可能在两周内更新 OV 限制载量。
这就意味着 DG 货代和跨境物流团队需要永久保持学习状态。不是看完一本 IATA DGR 就一劳永逸，而是每年至少一次系统性更新，每月关注增量变更。把"主动查 OV / SV"的纪律内化为日常动作的一部分，而不是当成额外负担。一旦养成这个习惯，你和那些只靠经验跑业务的同行会拉开质的差距——同样是货代，能稳定走"高变更品类"的人在市场上是稀缺资源，对应的议价能力和利润空间也大得多。
这是为什么 IATA CAT 6 培训证书只有 2 年有效期——它不是因为"两年后你忘了"，而是因为"两年后规则已经变了"。
新人入行最容易养成的坏习惯是"按经验做"。资深 DG 货代的工作方式恰恰相反——每一票货都把 OV / SV 当成"未知"重新查一遍。哪怕你昨天才查过同一个航司同一条航线，今天再查一次也不过 30 秒——但这 30 秒能避免一次毁灭性事故。
最后再强调一遍：DG 这个行当里，"经验"是把双刃剑。它让你在常规场景下反应快，但也让你在变更场景下错得更深。真正可靠的不是经验，而是流程——一套被你团队反复打磨、写进 SOP、嵌入日常的流程。把 OV / SV 查询写进流程，让它成为肌肉记忆而非主观判断，这是从"靠运气活下来"到"靠系统稳赢"的本质跨越。
下一篇我们继续：不受管制 / 例外数量 / 限量——到底哪些可以"走普货"。这是跨境电商最想搞清楚的合规问题——能不能不走完整 DG 流程，走简化通道。我们下次见。
In the fourth quarter of last year, a domestic freight forwarding company, following standard practice, shipped a batch of lithium-ion power banks to Saudi Arabia via a Middle Eastern airline with which it had collaborated for many years.The AWB, DGD, and SHC were all completed in accordance with IATA DGR standards; the UN 38.3 test summary was complete; and the outer packaging labels were properly affixed. However, upon arrival at Riyadh Airport in Saudi Arabia, the entire shipment was detained by customs. The investigation results were a headache for everyone: Saudi Arabia had just updated its SV (State Variation), adding additional import declaration requirements for a certain type of lithium-ion battery. The freight forwarder had used last year’s compliant template without checking the new SV, and ended up running right into trouble. The entire shipment was returned, accompanied by customs fines, a customer claim, and a three-month resolution process. Incidents like this play out repeatedly every year in the cross-border logistics industry. The root cause always points to the same pitfall: shipping this year’s cargo based on last year’s regulations. In this article, we’ll break down OV (Operator Variation) and SV (State Variation) once and for all, helping you avoid 90% of the pitfalls where “what worked yesterday gets rejected today.”
I. What Are OV and SV: The “Patch System” of IATA DGR
The core rules of the IATA DGR are universally applicable worldwide. However, airlines and countries around the world have different safety considerations, legal environments, and emergency response capabilities. Therefore, IATA has specifically established two “patch systems” in Chapter 2, “Limitations”:
| Abbreviation | Abbreviation | Issued by | Applies to |
|---|
| OV | Operator Variation | Carrying Airline | All DG cargo carried by this airline |
| SV | State Variation | National Civil Aviation Authority | All DG cargo within the country (origin, destination, and transit) |
Key Points:
- The IATA DGR Main Table sets the minimum threshold
- OV and SV specify stricter local regulations
- Follow the stricter set of rules: If OV is stricter than SV, follow OV; if SV is stricter than OV, follow SV
- You must never use “the Master Table says it’s allowed” to override “OV/SV says it’s not allowed”
II. What Do SV and OV Look Like in the IATA DGR Manual?
Open any edition of the IATA DGR; Chapters 2.8 and 2.9 list the following, respectively:
- 2.8 State Variations: Sorted by three-letter country code (e.g., USG for the United States, CHG for China, AEG for the United Arab Emirates, DEG for Germany)
- 2.9 Operator Variations: Sorted by airline two-letter codes (e.g., CA for Air China, LH for Lufthansa, EK for Emirates, BA for British Airways)
Each SV or OV has a unique number in the following format:
- SV:
USG-01、CHG-04、AEG-02 - OV:
CA-01、LH-08、EK-12
The number is followed by the specific details of the change—which may include prohibiting certain categories, tightening restrictions on certain categories, requiring additional documentation, or restricting certain aircraft types.
III. Common SV Content: 5 Major Categories of Changes
While the content of SVs varies by country, the common patterns of changes are similar:
1. Prohibition or Restriction of Specific UN Numbers
Example: A country’s SV regulations completely prohibit the transport of UN3480 (lithium-ion batteries shipped alone) on passenger aircraft.
2. Stricter Packaging/Quantity Requirements for Specific Classes
Example: A country’s SV requires that the net mass of a single package of Class 6.1 toxic substances be below the limit specified in the IATA Master Schedule.
3. Requirement for additional declarations or import permits
Example: A country’s Safety Authority (SV) requires that an import permit number be submitted 72 hours prior to entry for all Class 2 gas shipments.
4. Restrictions on Specific Aircraft Types / Routes / Time Periods
Example: A country’s safety authority (SV) stipulates that certain dangerous goods (DG) may not be transported on night flights or through specific military/civilian joint-use airports.
5. Emergency Contact Requirements
Example: A country’s SV requires that the 24-hour emergency phone number must be a local number within that country and cannot be an overseas number.
IV. Frequently Covered Topics in OV: 8 Common Types of Changes
The content of OV varies significantly among airlines; below are 8 common OV patterns:
1. Complete Prohibition of Certain Classes or UN Numbers
Example: An airline may state in its OV, “Class 1 explosives are strictly prohibited” or “Class 5.2 organic peroxides are strictly prohibited.”
2. Stricter Lithium Battery Rules
Lithium batteries are the area where OV revisions occur most frequently. Many airlines’ OV regulations are stricter than the IATA Master Schedule; for example:
- Prohibition of Section IA cargo
- Prohibition of pure batteries exceeding 100 Wh
- Prohibition of end-of-life or recalled lithium batteries (most airlines)
- Prohibition on shipping complete self-balancing scooters and electric scooters
3. Limits on total quantities per AWB, per ULD, or per flight
Example: An airline’s Operational Manual (OV) stipulates that the total watt-hours of lithium batteries within a single ULD must not exceed a certain threshold.
4. Requirement for additional 24-hour emergency services
Example: A certain airline requires shippers to provide the phone number of an emergency service provider on the airline’s approved list.
5. Requirement for Electronic DG Declaration
Example: A certain airline accepts only e-DGDs and does not accept handwritten DGDs.
6. Stricter Labeling and Packaging Requirements
Example: A certain airline requires that certain classes of cargo must use UN-compliant packaging from a specific supplier.
7. Restrictions on Transit Airports
Example: A certain airline prohibits certain classes of cargo from transiting through specific hubs in its network.
8. Advance Declaration Window
Example: A certain airline requires that a complete DGD be submitted for dangerous goods (DG) 48 hours prior to flight departure.The advance declaration window is often linked to the airline’s internal security screening and review capacity; during holidays or periods of staffing shortages, the window may be extended from 48 hours to 72 hours. These seasonal variations also fall within the scope of OV operations and require ongoing monitoring.
V. How to Systematically Check OV and SV
In practice, checking for OV and SV is an essential step in the dangerous goods dispatch process. Below is the complete query process:
Step 1: List all “nodes” along the entire transport chain
- Country of origin
- All transit countries (including stopovers)
- Country of Destination
- Origin Carrier
- Any connecting carrier
Step 2: Check SV/OV for each stop
- Country: Check IATA DGR Chapter 2.8 for SV
- Airline: Check IATA DGR Chapter 2.9 for OV
Step 3: Cross-check for discrepancies with the main table
- If the master table permits it but OV/SV prohibits it → Follow OV/SV (cannot be shipped)
- If the master table allows 5 liters per item, but OV/SV specifies 2 liters per item → Follow OV/SV (stricter requirement)
- If the main table requires a standard DGD and OV requires an e-DGD → Follow OV
Step 4: Retain Records for Future Reference
- Retain SV/OV query records for each shipment for at least 2 years
- In the event of a retrospective audit by customs or the airline, the query records can be produced to demonstrate compliance and due diligence
- Archived records must include: query date, SV/OV reference number(s) queried, person who performed the query, conclusion, and whether the results affected shipment
You can use OneCargoKit’s Dangerous Goods Check to quickly cross-reference high-frequency prohibited items in OV/SV before assigning tasks; the tool includes built-in OV alerts for common carriers.However, the current edition of Chapter 2 of the IATA DGR remains the authoritative source for comprehensive OV/SV inquiries—the tool serves as a pre-screening tool, while the manual is the final authority.
VI. The 5 Scenarios Where Cross-Border Logistics Teams Are Most Likely to “Use Last Year’s Rules”
OV/SV updates occur almost every year, and for some highly sensitive categories (especially lithium batteries), changes can happen several times a year. The following five scenarios are where using outdated rules is most likely to cause problems:
1. Lithium Battery OV Updates
The PI 965–970 guidelines for lithium batteries are updated almost every one to two years. The watt-hour thresholds in Section II, limits on the number of batteries per package, and specifications for handling labels may all be subject to minor adjustments. The most common pitfall for newcomers is thinking, “I shipped this shipment last year, so I’ll just do the same this year.”
2. Safety Regulations (SV) in Countries with Frequent Changes (e.g., Saudi Arabia, UAE, India)
SVs in Middle Eastern and South Asian countries are updated more frequently than in Europe and the U.S. Saudi Arabia, in particular, has tightened numerous SVs related to customs and security checks over the past two years, causing many established routes to “suddenly become impassable.”
3. Post-COVID-19 Pharmaceutical Cold Chain SVs
Regulatory requirements for vaccines, medical samples, and biopharmaceuticals have undergone significant updates in various countries since 2020. Cold chain freight forwarders should pay special attention to regulations related to UN3373 and UN2814.
4. Safety Regulations for Self-Balancing Scooters and Electric Bicycles
For complete vehicles containing lithium batteries—such as self-balancing scooters and electric bicycles—nearly all major airlines have tightened restrictions or imposed bans over the past 3–5 years. Airlines that previously accepted these shipments may no longer do so.
5. Transit Hubs and OV
Major transit hubs such as Dubai, Singapore, Hong Kong, and Frankfurt frequently adjust their OV requirements for transshipment of dangerous goods (DG). If the transit point on a route changes, the compliance criteria for the entire shipment must be reassessed.
VII. “Integration Points” for SV/OV in a Freight Forwarder’s Daily Work
OV/SV is not an isolated “query action”; it needs to be integrated into multiple stages of a freight forwarder’s daily workflow. Understanding these integration points allows compliance to become an automated muscle memory, rather than relying on manual reminders every time:
1. Embedding During the Client Quote Request Stage
When a client sends a quote request, the first step is not to calculate freight charges, but to clarify the UN number, commodity category, origin, destination, and transit time. Once these five items are confirmed, immediately mentally review the latest OV and SV—is shipment permissible, are there any prohibitions, and are there any additional requirements?If the carrier for the outbound flight has an OV ban on this type of cargo, you should inform the client directly during the inquiry stage—suggesting they “switch to Carrier X” or “use the ocean freight segment”—rather than discovering the shipment cannot proceed only after accepting the order.
2. Inclusion in the Quote
DG cargo quotations must clearly state, “Based on Airline X’s current OV for Month X,” and specify that the quote is subject to change if OV or SV changes before shipment. This line may seem redundant, but it provides a contractual basis should the client later dispute a price increase.
3. Incorporation During Booking
Double-check the OV before submitting the booking—many airlines update their OV monthly, and there may be a few days between the quote and the booking. Automatic order rejections by the booking system often occur because the OV has tightened and you didn’t notice.
4. Incorporate during the DGD issuance stage
Once the DGD draft is complete, review the OV/SV one more time before signing—confirm that all fields (emergency contact number, aircraft type, authorization, special provisions) comply with current OV/SV requirements.
5. 24 Hours Before Departure
Recheck the SV/OV one day before shipment, especially in the event of extraordinary circumstances such as political, geopolitical, or natural disasters (e.g., sudden airspace restrictions in a country or an airline’s emergency suspension of flights).
Incorporate these five checkpoints into the company’s internal SOP document. New employees should follow the SOP, and experienced employees should make it a habit; this will significantly reduce the OV/SV error rate across the entire team.
VIII. What to Do When SV and OV Conflict
In practice, situations often arise where “SV permits but OV prohibits shipment” or vice versa. The guiding principle is:
- Always follow the stricter regulation
- OV cannot be more lenient than SV (airlines cannot “waive” national regulations)
- SV cannot be more lenient than ICAO Technical Instructions (a country cannot “waive” international conventions)
- The DG Master Table is the baseline; OV and SV can only be made stricter, not more lenient
Example:
- The IATA Master Schedule states that the weight limit for a certain UN-numbered passenger aircraft is 5L
- A certain country’s SV specifies a weight limit of 2L
- An airline’s OV states that this UN number is completely prohibited from transport
- Conclusion: Follow the OV; shipment is completely prohibited
When assigning shipments, run through this “strictest to least strict” sequence, and it will become clear whether the entire shipment can be transported.
Practical Tip: Compile the OV/SV review results for each shipment into an internal “Route Assessment Table" for each shipment, including five columns: SV of the country of origin, SV of the destination country, SV of transit countries, OV of the originating carrier, and OV of the connecting carrier. Each column should be marked either "OK" or with the specific restrictions.Keep this sheet on file for future reference; should any issues arise later, it will serve as proof that you have fulfilled your compliance investigation obligations. This record-keeping practice is not only useful for internal audits but also serves as critical evidence when dealing with insurance claims or responding to customs liability claims. Many large DG freight forwarding companies manage this sheet as a “sister document” to the DGD.
IX. Recommended Frequency for OV/SV Queries
| Role | Recommended Frequency |
|---|
| Freight Forwarder / Operations | Systematically update your OV/SV reference sheet at least once a month |
| Cross-Border E-Commerce Operations | Recheck OV/SV for all product categories shipped on a quarterly basis |
| Factory Exports | Reconcile accounts with freight forwarders at least once every six months |
| Large Shippers | Monitor the latest edition of the IATA Cargo Operations Bulletin weekly |
Many companies also subscribe to IATA’s official Dangerous Goods Subscription, which provides monthly updates on SV and OV—a highly valuable resource for teams that frequently ship dangerous goods.
X. Common Misconceptions
- Misconception 1: If a shipment meets the main table requirements in the IATA DGR, it’s guaranteed to be accepted—Wrong. It may still be prohibited under OV or SV.
- Misconception 2: Routes that worked last year will work the same this year — Wrong. OV/SV change every year.
- Misconception 3: If the airline didn’t tell me about an OV change, it means there wasn’t one — Wrong. Airlines do not notify freight forwarders individually of OV changes; you must proactively check.
- Misconception 4: SVs are merely recommendations — Wrong. SVs are enforceable under national law; violations may result in seizure by customs and fines.
- Misconception 5: If the SV requirements for the country of origin are met, you don’t need to worry about the destination country’s SV — Wrong. SV requirements must be met at every point along the entire transport chain.
- Misconception 6: OV information isn’t publicly available —— Wrong. All OV information is publicly available in Chapter 2.9 of the IATA DGR; simply subscribe to the IATA database.
- Misconception 7: There’s no need to check the SV for air traffic control zones that are merely overflown —— Partially correct. If the flight is merely overflying without a stopover, it’s usually not necessary to check, but the SV must be checked for any country where the aircraft takes off, lands, or is loaded/unloaded.
- Misconception 8: OVs do not need to be checked for charter flights —— Wrong. Charter flights are also operated by airlines and must still comply with OVs.
- Misconception 9: The English version of SV/OV is the authoritative one —— Yes, but some countries also publish versions in their local languages; in case of conflict, the IATA English version takes precedence.
- Misconception 10: OV/SV information retrieved using AI tools is authoritative —— Wrong. AI training data may be outdated; OV/SV must be based on the current IATA DGR Manual.
XI. Practical Checklist: Pre-Departure OV/SV Review
- [ ] SV for country of origin has been verified
- [ ] SV for all transit countries verified
- [ ] SV for the destination country has been verified
- [ ] OV for the originating carrier has been verified
- [ ] OV for connecting carrier(s) verified (if applicable)
- [ ] Lithium batteries: OV—specifically verified (this is a high-risk item)
- [ ] OV/SV numbers have been recorded in the dispatch file
- [ ] Any instances of “Permitted on the Master List, but Prohibited by OV/SV” have been identified
- [ ] 24-hour emergency contact number complies with SV localization requirements
- [ ] Emergency service provider is on the airline’s approved list (if required by OV)
- [ ] DG declaration deadline complies with OV requirements
Making OV/SV verification the final mandatory step in the SOP during dispatch can prevent 99% of incidents where a shipment “was accepted yesterday but rejected today.”Use the Surcharge Estimator to factor in potential OV/SV additional declaration fees, enhanced packaging fees, and emergency service fees during the quotation stage to avoid billing disputes later on.
XII. Classification Method for the Three Job Categories
| Position | OV/SV Key Actions | Output |
|---|
| Freight Forwarder / Operations | Monthly update of OV/SV quick reference table + pre-shipment review for each shipment | Compliant Shipping Solutions |
| Cross-Border E-Commerce Operations | Quarterly re-inspection of OV/SV for shipped product categories | Logistics Solution Adjustments |
| Company Compliance Position | Subscribe to the IATA database + Monthly internal bulletins | Team Compliance Threshold |
For cross-border e-commerce teams exporting high-OV/SV categories such as lithium batteries, aerosol cosmetics, and pharmaceutical cold-chain products, it is strongly recommended to establish a dedicated “Compliance Change Tracking Role,” even if only on a part-time basis. The value of this role lies in “preventing incidents”—while difficult to quantify, the cost of a single incident far exceeds the annual salary of this position.
XIII. Compliance and Boundary Reminders
- This article is a practical summary based on the publicly available IATA DGR Chapter 2 “Limitations” framework and does not constitute legal, compliance, or safety advice
- Specific OV/SV content is subject to version updates; refer to the current edition of IATA DGR Chapters 2.8 and 2.9
- National civil aviation authorities may issue temporary SVs during the year (particularly in situations such as COVID-19 or geopolitical conflicts); check the latest notices before shipment.
- Airline OV changes may be released at irregular intervals; pay close attention to bulletin boards and notifications in the booking system
- OVs for lithium batteries, self-balancing scooters, and electric vehicles are currently the areas subject to the most frequent changes; monthly updates on these topics are recommended
- For SVs involving military airports, restricted areas, or sensitive categories, it is recommended to entrust handling to a freight forwarder with professional international cargo qualifications
XIV. Conclusion: OV/SV are the “most time-sensitive” compliance issues in the DG supply chain
Most rules in the DG supply chain are relatively stable—the nine major categories remain unchanged, UN numbers remain unchanged, and PI numbers remain unchanged. However, OV and SV change every year. Geopolitical developments, new events, accidents, and new technologies—any of these can trigger new SV or OV requirements.For example, if an investigation into an air crash concludes that a certain type of cargo poses a risk, it often triggers a new round of collective tightening of SV and OV regulations; if a security screening error suddenly occurs on a major route, the operating carrier may update its OV load limits within two weeks.
This means that dangerous goods (DG) freight forwarders and cross-border logistics teams must remain in a constant state of learning. It’s not enough to read the IATA DGR once and be set for life; instead, you need to conduct a systematic review at least once a year and monitor incremental changes every month. Make the discipline of “proactively checking OV/SV” an integral part of your daily routine, rather than treating it as an extra burden.Once you develop this habit, you’ll create a qualitative gap between yourself and peers who rely solely on experience to run their businesses—among freight forwarders, those capable of consistently handling “high-change categories” are a scarce resource in the market, and their corresponding bargaining power and profit margins are significantly greater.
This is why the IATA CAT 6 training certificate is valid for only two years—not because “you’ll have forgotten it after two years,” but because “the rules will have changed by then.”
The worst habit newcomers to the industry tend to develop is “relying on experience.”The approach of seasoned DG freight forwarders is exactly the opposite—they treat the OV and SV for every shipment as “unknowns” and double-check them each time. Even if you checked the same airline and route just yesterday, it takes only 30 seconds to check again today—but those 30 seconds can prevent a catastrophic incident.
Let me emphasize this one last time: in the DG industry, “experience” is a double-edged sword. It allows you to react quickly in routine situations, but it also causes you to make even bigger mistakes when things change.What’s truly reliable isn’t experience, but process—a process that your team has repeatedly refined, codified into SOPs, and embedded into daily operations. Incorporating OV/SV checks into your process, turning them into muscle memory rather than subjective judgment, is the fundamental leap from “surviving by luck” to “winning consistently through systems.”
In the next post, we’ll continue with: Unregulated Items / Exceptions / Quantity Limits—which ones can actually be shipped as “general cargo.” This is the compliance issue that cross-border e-commerce businesses are most eager to clarify—whether they can bypass the full DG process and use a simplified channel. See you next time.
