Make an amendment to export declarations (C81)

Use the online service or postal form (C81) to make an amendment to export declarations, export statistical schedules for statistical purposes only.


Amend online (sign in using Government Gateway)

Amend by post (use this version if you're an agent or if you can't use the online form)


Use this form to make a change to export declarations, export statistical schedules and data sent by period entry or through CHIEF.

This form is used for statistical purposes only. Revisions to trade statistics are made in accordance with EU legislation. You should enter the details from the original entry and the amended details.

You can either:

  • use the online service
  • fill in form on screen, print and post it to HMRC

To make an amendment, you need a Government Gateway user ID and password. If you do not have a user ID, you can create one when you use the service.

If you use the online form, you’ll get a reference number that you can use to track the progress of your form.

Email HMRC to ask for this form in Welsh (Cymraeg).

Information you’ll need

You’ll need the following details to hand to help you complete the online form:

  • company details
  • details of the declaration you want to amend, including Unique Consignment Reference, Entry Processing Unit, entry number, and date of shipment
  • details of the declaration entries you want to amend, including what you originally declared, and the correct details

Before you start using the postal form

If you’re using an older browser, for example, Internet Explorer 8, you’ll need to update it or use a different browser. Find out more about browsers.

You’ll need to fill in the form fully before you can print it. You cannot save a partly completed form so we suggest you gather all your information together before you begin to fill it in.
