Amend or cancel simplified import declarations

How to amend or cancel simplified frontier declarations, C21s and non-special procedure non-monetary supplementary declarations.

You can request the amendment or cancellation of declarations submitted using the simplified customs declaration process, for:

  • Customs Handling of Import and Export Freight (CHIEF)
  • the Customs Declaration Service

Check if you need to request a simplified frontier declaration or C21 amendment

Any requests for amendments not detailed in this section will not be accepted and will be returned unactioned.

If your request concerns box 6 or Data Element (DE) 6/18 — total packages

If the original commercial import paperwork does not support the quantity, further evidence is required (for example, for short shipments, correspondence with the supplier is required).

If a short shipment is only identified on eventual receipt of goods, then a new simplified frontier declaration or C21 should be submitted when the goods arrive.

You must submit a simplified frontier declaration or C21 amendment form for the original declaration or C21. This should show details of the declaration or C21 and confirm ‘missing quantity now accounted for on entry…’.

You should complete the sentence with the new CHIEF entry or Customs Declaration Service movement reference number details.

If your amendment includes simplified entries to the customs warehouse, confirmation is required of the location of the goods within the email.

Overages declared on a simplified frontier declaration and delivered to the customs warehouse should be booked into the customs warehouse stock records.

For typos, if the commercial paperwork supports the amended quantity, an amendment request is not required.
