Electronic customs products and solutions

We offer solutions and incentives to help you provide data and remain compliant with international regulations

Increasingly, more countries are requiring electronic customs data to accompany imported items. Providing electronic customs data will ensure that existing, emerging and future legislation, security arrangements and customs requirements in overseas destinations are met. This data needs to be completed accurately and in full to meet new requirements and ensure friction-less processing through overseas customs.

We offer solutions and incentives to help you prove data and remain compliant with international regulations.

Please be assured that if you are unable to provide full customs data you will not be prevented from posting with us. However, items are at risk of being negatively affected when they arrive in the destination country if complete electronic customs data is not presented.

Have a look at some of the country requirements

HS classification services

Harmonised System codes (otherwise known as HS or Tariff Codes) form part of the data requested in customs declarations forms CN22 and CN23. The Universal Postal Union (UPU) demands that these customs forms are completed accurately and in full to facilitate a rapid clearance in the recipient country.

Our Managed HS Classification Service provides a solution for retailers looking for HS codes for items in their product catalogue and to help ensure compliance with export prohibitions and restrictions. Our service adds a HS code to each item in the retailer’s catalogue. Additionally, the service also provides the retailer with a report of potential prohibitions and restrictions which may apply to items in their product catalogue if exported from the UK.

The HS and Prohibition & Restriction codes can then be uploaded to the retailer’s product database or entered directly into the merchandising system(s). No integration is required between the retailer’s web solution and our systems.

We have several guides which will help you decide that our Managed HS Classification Service will make it easier for you to do business:

The Managed HS Classification User Guide (pdf, 754.09 KB) provides more information on what the Managed HS Classification service is, how the product works, what is needed to access the services being offered under this product, data requirements, and information on how to get support.

The Managed HS Classification Services Terms and Conditions (pdf, 127.88 KB) set out our agreement with the retailer with regards to this product.

The Managed HS Classification Rate Card (pdf, 157.33 KB) provides an overview of the price structure for the HS Code classification service.

Shipping platforms that automatically provide customs data

Our user-friendly online platforms, Click & Drop and Pro Shipping allow you to enter the required customs information and print the right labels and item identifier (S10 barcode) for your parcels.

Watch our video for a guide on how to complete all the required customs information using Click & Drop.

Click & Drop - How to create international orders with the required customs information

Royal Mail Click & Drop or Pro Shipping make your life easier

  • You enter the data into the system, which will then print out all of the required labels for you to affix to the parcel – ensuring you meet requirements for all destinations
  • No need to write labels out manually - saving you time
  • If you post a lot of parcels, you can build up a product catalogue, so that you can enter repeat information with a click instead of having to write or type it again for each parcel
  • As the data is sent ahead of the parcel, this should allow for a more seamless customs process in the country of destination

Setting default customs information with Royal Mail Click & Drop

If you regularly send the same kind of items overseas, you can save time by setting the same electronic customs information which will apply to all of your orders in Click & Drop. For example, if you regularly sell t-shirts, all of your products will usually have the same Harmonised System code and customs description. Any missing or incomplete customs data will be automatically updated with the values you set – whether your orders are created manually, imported via spreadsheet, downloaded from an eCommerce marketplace or web store.

We have also updated the COSS and SAPI specifications so that you can provide the right data fields. This includes the addition of the S10 barcode that is required for overseas posts to be able to access the data and provide it to their import customs agency for clearance. iShipper follows the same specifications as COSS and has also been updated.

These are bespoke shipping options - please speak to your Account Manager for more information.

We have updated and shared the specifications for providing electronic customs data to providers of third party shipping solutions. They are aware of the requirements and working towards implementing them.


The specifications for providing electronic customs data to providers of other shipping systems have been updated and shared; these companies have been advised that this data must be captured and provided.

  • Intersoft
  • Linnworks
  • Madcapsule
  • Scurri
  • ShipStation
  • Smartfreight
