Customs Declarations

How to view and edit customs forms in ShipStation. Includes where to add Harmonization code.

A Customs Declaration lists all the items contained within a shipment when that shipment crosses international borders. Customs agencies require customs forms to help them regulate the flow of goods in and out of each country.

ShipStation automatically creates customs declarations for orders that import or are created with an international shipping address. How these declarations are created depends on your International Settings in ShipStation. The default behavior is to create customs declarations based on the items that will be included in the shipment.

ShipStation will send the customs declarations information to the carrier when you create the label for the shipment. If a separate form is required, the form is sent to your ShipStation account at the same time as the label.

To see how to view and print the customs form, review the Print Customs Forms article.

View & Edit Declarations for Orders

For international orders, ShipStation automatically creates customs declarations based on your account settings.

To view or adjust customs information for a shipment, you'll use the Customs Declarations section in the Shipping Sidebar (available both in the Orders grid sidebar and the Order Details sidebar).

When you create the international label for this shipment, the postage provider will use this information to create the required customs document(s), which you can then print through ShipStation.

Add Harmonization Codes to Product Defaults

You can add Harmonization Codes manually, like above, or automatically by adding the Harmonization Code to the Product Record's Customs details in ShipStation.

Notes About Customs Declarations

  • Each carrier outputs their customs declarations in their own proprietary format. To find out a carrier's specific international shipping requirements, please contact the carrier directly.

  • A commercial invoice details the agreement between the shipper and receiver, but CN22/23 customs forms do not. The agreement details include who’s responsible for the shipment as well as the duties and taxes, and whether or not they’ve already been paid.

  • A CN23 form can be substituted for a CN22. However, a CN22 cannot substitute a CN23 form.

  • For providers that send their customs forms to your ShipStation account, they do so at the same time they send the label.

  • The Customs Forms column in the Shipments grid will indicate if the customs declarations are included on the label, electronically submitted, or in PDF form that you can download and print.

  • A phone number or email for the buyer (also known as the consignee) is required for most international shipments. You may update this information in the Ship-To information.

  • If shipping to a business, you may now provide the VAT number for the recipient.

  • Some carriers may have a limit to the number of items allowed on their customs declarations forms. If this is the case for your carrier, you may need to consolidate some of your customs declaration line items before your customs forms will print properly.

    If you are unsure if your carrier has such a limit and your customs forms printed via ShipStation appear to be missing items, please contact your carrier to confirm.

  • For UPS shipments that include carrier insurance and are valued at $1000 or more, a High-Value Report will be included in the form's PDF.

  • After 31 December, 2020 you will be able to print CN23 forms and commercial invoices for your Royal Mail shipments directly from ShipStation.

  • For more information on UK Customs Regulations, please review the GOV.UK Import and export: customs declarations, duties, and tariffs website.
