How does Brexit affect carriers and fulfilment providers?

We recommend that you contact your carrier account managers to make sure they have your VAT and EORI numbers on file. This can help if you do not include a tax identification number when creating a shipment and also can ease the carrier’s ability to help you clear customs with less risk of contacting you.

Below are summaries for how each carrier handles international documents as well as links to the carrier's own resources for more details.

Royal Mail

ShipStation uses Intersoft’s Royal Mail integration to deliver Royal Mail shipping services. This integration allows adding VAT and EORI numbers to customs forms at the time of label creation.

We recommend adding your EORI and VAT numbers to your ShipStation International Account Settings.

Customs forms and commercial invoices with Royal Mail:

  • Royal Mail will automatically provide the CN23 form for your shipments after 31 December, 2020.

  • ShipStation also generates a commercial invoice, which you must print and include with your shipment.

You may wish to review the Royal Mail Brexit information page for more details.

DHL Express

DHL Express allows ShipStation to provide Tax IDs when we generate these labels. ShipStation already electronically transmit the commercial invoice to DHL Express. While you are not required to include a printed copy of the commercial invoice in your shipment, you are free to print it and include it if you choose.

You may wish to review the DHL Express Brexit Guide or their Trade After Brexit presentation for more details.


DPD will not be accepting paper commercial invoices. ShipStation will pass the customs information to DPD and DPD will submit your commercial invoice electronically.

Initially, DPD will import via certain hubs and therefore parcels will be charged VAT based on their clearance hubs when shipping from Great Britain.

  • NL Clearance Hub: Netherlands, Belgium, Luxembourg, Poland, Germany, Norway, Denmark, Sweden, Finland

  • FR Clearance Hub: France, Portugal, Italy, Czech Republic, Hungary, Slovenia, Slovakia, Romania, Latvia, Lithuania, Estonia, Greece, Bulgaria, Austria, Croatia

  • ES Clearance Hub: Spain only

  • IE Clearance Hub : Republic of Ireland only

Evri (formerly Hermes)

Evri (formerly Hermes) currently does not support electronic submission for commercial invoices. ShipStation will generate commercial invoices to be printed out with your Evri shipments.

You must include three copies of the commercial invoice with all Evri international shipments.

Parcelforce Worldwide

Parcelforce will start supporting DDU services via their euroEconomy service. Additionally, ShipStation will start providing you with all necessary forms for Parcelforce.

Customs forms and commercial invoices with Parcelforce:

  • Parcelforce will return a CN23 form to ShipStation for all shipments that require it. This form is generated from your customs declarations in ShipStation.

  • Parcelforce will return a commercial invoice to ShipStation for all shipments that require it. You must print three of these and include with your shipment.


Only EPH Parcelforce services will require a CN23 form. EPB and EPP will only require a commercial invoice.

There is no way for ShipStation to transmit EORI to UPS in an explicit field. We can only transmit VAT. However, we will include this information on the commercial invoice notes.

To submit customs electronically, you must enable electronic submission for customs forms with UPS. This feature is not enabled by default. To enable electronic submission, follow the steps in the UPS Paperless Invoice help page.

If you do not have electronic submission enabled, print three copies of the commercial invoice in ShipStation and include them with your shipment.

ShipStation will send the EORI and VAT numbers you’ve added to ShipStation when creating your label. FedEx will use this information to electronically transmit customs and declaration information, if electronic submission is supported by the destination country.

You may be required to upload a header and signature image in ShipStation for some countries. Review the Upload ETD Letterhead and Signature section of our FedEx integration article to learn how to upload these assets.

Fulfilment Providers (3PL)

If you’re currently using a third party fulfilment partner (3PL) or thinking of partnering with a 3PL in the future to manage your pick, pack, and dispatch processes, the customs and VAT changes we highlighted earlier will also affect your processes and obligations with 3PL partners starting 1st January 2021.

If you’re not holding inventory outside of the UK, consider locating inventory in the EU to be closer to your customer (we have partners who can help).

If you’re using a 3PL, consider exporting more inventory before the 31st December 2020 deadline to save time and money.
