It all starts with valid HS codes
Need to confirm a code sent by a client or supplier? Want to make sure previously classified products still have valid codes? HS codes can and do change, so regular checks are essential.
With our API, you can:
- Validate HS codes
- Get suggestions for incomplete codes
- Retrieve HS code descriptions
- Browse HS codes with ease
Note: The EU and Great Britain use 8‑digit and 10-digit commodity codes based on the 6‑digit HS codes — more accurately referred to as CN, TARIC, or UKGT codes. However, since “HS code” is widely used, we’ll stick with that term.

Calculate duties & taxes
Duty and tax rates change regularly. By integrating our data into your systems, you’ll always have an up-to-date answer to this age-old question.
Use our Duty Calculation API to calculate import duties for both the EU and Great Britain. We also provide national taxes — such as VAT and excise duties — for Great Britain and several EU member states, including the Netherlands, Belgium, Sweden, Germany, and Italy.

Check required additional codes
With our API you can:
- Retrieve a list of required additional codes
- Validate additional codes
- Access clear descriptions for each code
Quick, accurate, and essential for smooth customs clearance.

Is the necessary paperwork in order?
Even with a valid HS code and the correct additional codes, there may still be prohibitions and restrictions on import. Without the required documents, your goods still won’t clear customs.
Use our API to check which documents are required and identify the corresponding certificate codes for SAD box 44. This helps ensure your customs declarations are complete and compliant.
In SAD box 44, you can also enter particular provision codes, or Y codes. These aren’t tied to physical documents- instead, they’re used to declare that your goods qualify for certain exemptions (e.g. a product being excluded from a certain restriction list).
With our API, you can:
- Retrieve a list of required certificate codes and/or Y codes
- Get descriptions of certificate and/or Y codes
Validate a list of codes to ensure they’re sufficient for customs clearance

Validate customs declarations
Many businesses rely solely on error messages from customs declaration systems, but that’s a risky approach. Customs authorities use predictive algorithms to flag likely errors and identify non-compliant filers. To avoid unnecessary scrutiny, it’s best to validate your declarations in advance.
With our API, you can:
- Validate HS codes
- Validate additional codes
- Validate certificate codes and Y codes
- Check prohibitions and restrictions related to customs value, net weight and/or supplementary units
Proactive validation means fewer delays, fewer penalties, and greater peace of mind.
