What is NCTS5 T1 transit?

NCTS5 (New Computerised Transit System Phase 5) is the EU's electronic transit system. A T1 declaration covers non-EU goods moving between EU customs offices under customs supervision, such as air cargo arriving at one airport and trucked to another for clearance.

What format does NCTS5 use?

NCTS5 uses XML electronic messages, not PDF documents. The key message is IE015 (CC015C) for transit declarations. One IE015 message can contain up to 1,999 House Consignments with up to 999 Consignment Items each.

Can this tool handle thousands of e-commerce parcels?

Yes. The tool automatically merges parcels with the same HS code, reducing thousands of rows to a manageable number of Consignment Items. All processing happens in your browser with no server upload required.

Step 1 — Transit Route

Enter customs office codes for departure and destination. Type to search by code, city or airport name, or enter a custom code.

MAWB (Master AWB) *

Office of Departure *

Office of Destination *

LRN (Local Reference Number)

Guarantee Type

GRN (Guarantee Reference)

Step 2 — Upload Parcel Data

Upload your CSV or Excel file. Required columns: Goods Description, HS Code (6-digit min), Gross Weight (kg), Number of Packages. HAWB is optional.

Column mapping: The tool auto-detects columns named HAWB, Description/Goods, HS/HS Code, Weight/Gross, Packages/Pieces. You can also map manually after upload.

HS Code note: NCTS5 requires 6-digit HS codes. The first 6 digits are harmonized worldwide by WCO — Chinese (10-digit), EU (CN 8/10-digit), and US (HTS 10-digit) codes all share the same first 6 digits. This tool automatically extracts the first 6 digits regardless of origin. No conversion needed.

IE015 (CC015C) Data Structure

The IE015 message uses a 4-layer hierarchy:

Transit Declaration (IE015 / CC015C)

Consignment (1 per declaration)

Office of Departure / Office of Destination

Country of Routing (transit countries)

House Consignment (max 1,999)

Transport Document Reference = HAWB number

Consignment Item (max 999 per HC)

HS Code 6-digit, mandatory

Goods Description

Gross Mass (kg)

Number of Packages

One declaration can hold up to 1,999 HAWBs (House Consignments), each with up to 999 different HS-code line items. This means a single XML file can cover an entire MAWB with thousands of e-commerce parcels.

Merge Strategy

When multiple parcels under the same HAWB share the same 6-digit HS code, they can be merged into a single Consignment Item by summing their weights and package counts. This is the recommended approach and dramatically reduces the number of line items — e.g. from 10,000 parcels to ~500 merged items.
