The all-in-one API for import and export

The most advanced and fastest way to make sure all your customs affairs are 100% customs compliant. With real-time trade tariff data for the UK and the EU.

It all starts with valid HS codes

Our API will help you to validate HS codes and tell you if they are complete and current.

You may want to check if an HS code a client or supplier sent you is valid, for example. Furthermore, HS codes change. If you’ve classified products a while ago, you should probably recheck if the HS code is still valid.

  • Validate HS codes
  • Show possible completions of incomplete HS codes
  • Get the description of HS codes
  • Browse through HS codes

NB: the EU and Great Britain use 8‑digit and 10-digit commodity codes that are based on the 6‑digit HS codes, so technically we should talk about UKGT codes, CN codes and/​or TARIC codes. However, since the usage of the term HS code is so common, this is what we’ll use as well.

Calculate duties & taxes

What’s this going to cost me?

Duty and tax rates change. Integrate them into your own systems so that you’ll always have an up-to-date answer to this age-old question.

You can use our duty calculation API to calculate import duties for the EU and GB. We provide national taxes (VAT and Excise duties) for Great-Britain, and many EU memeber states, such as the Netherlands, Belgium, Sweden and Germany. 

Check required additional codes

In many cases, a customs declaration requires entering additional codes.

These can be related to tariff preferences, prohibitions and restrictions, antidumping, VAT or excise. Using our API you can get an overview of the required additional codes and/​or validate a list of additional codes.

  • Get a list of additional codes
  • Validate additional codes
  • Get a description of additional codes

Is the necessary paperwork in order?

Check required certificate codes or Y codes.

Even if you have a valid HS code and the right 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 find out which documents you need and which are the corresponding SAD box 44 certificate codes.

Note that in SAD box 44 you can also enter particular provision codes, also known as Y codes. These codes are not related to an actual certificate. Instead, they are a way for you to declare that the commodity is on a list of goods which is exempted from a particular restriction, for example.

  • Get a list of required certificate codes and/​or Y codes
  • Get a description of the certificate and/​or Y code
  • Validate a list of certificate codes and Y codes – will this set of codes clear customs?

Validate customs declarations

The validations mentioned above can be combined and lead to our API’s most powerful feature: automatic validation of customs declarations before they are sent to customs.

Many companies are relying on the error messages returned by a customs declaration system, but this is asking for trouble. Customs authorities use predictive algorithms to check who is likely to file incorrect declarations. 

Therefore, it’s better to check your declarations before they go to customs.

  • Validate HS code
  • Validate additional codes
  • Validate certificate codes and Y codes 
  • Check prohibitions and restrictions related to customs value, net weight and/​or supplementary units
