A customs declaration can also be corrected after it has been filed, but the scope of the correction depends on whether the goods have already been released. In the UK's CDS, a declaration that has not yet cleared is amended yourself in your CDS software; after clearance you need to contact HMRC (within 3 years of acceptance), and the amendment can involve an additional payment or a refund.

When a customs declaration can be corrected
Yes, but the scope of the correction depends on whether the goods have been released and on the system in which the declaration was filed. First establish whether the declaration is unreleased (you amend it yourself) or released (you must apply to the authority).
United Kingdom (CDS)
- Before release - you amend the declaration in your CDS software without contacting HMRC, until you receive the final tax calculation message. If you cannot amend it, you can cancel and resubmit, but only before clearance.
- After release - you cannot amend in your software; you apply to HMRC. You have up to 3 years from acceptance of the declaration (or a control being applied, whichever is earlier) to amend and 90 days to cancel. Underpayments are handled with form C2001 and overpayments with a C285 repayment claim (GOV.UK).
European Union (UCC)
On application by the declarant and with the customs authority's permission, the particulars of a declaration can be amended after acceptance (Article 173(1) UCC) - but not after the goods have been released, the declarant has been told of an examination, or an error has been found. After release, an amendment is possible on application within 3 years of acceptance (Article 173(3) UCC). Article 174 UCC concerns invalidation of a declaration, not its amendment. We compare the details in amending or invalidating a customs declaration.
Common reasons for corrections
Wrong tariff classification, a value that does not match the commercial invoice, a missing T1 for transit, a wrong EORI number or country of origin. A correction may mean an extra payment with interest or a refund. Practical steps once you find an error are in what to do about an error in a customs declaration.
Records and evidence of due diligence
In the EU customs records are kept for at least 3 years (Article 51 UCC), in the UK for 4 years (GOV.UK). This covers invoices, consignment notes, declarations and proof of payment. With every correction keep the reason for the change - it is your evidence of due diligence in an audit.
The role of a customs agent
An agent can prepare the correction and file the application, but only on the principal's authority. Liability depends on the type of representation - see direct and indirect customs representation.

Frequently asked questions
Can a customs declaration be corrected after it has been filed?
Yes. In the EU, the declarant may, on application and with the customs authorities' permission, amend the details of a declaration after it has been accepted (Article 173(1) UCC) — but not after the goods have been released, the declarant has been told of an examination, or an error has been found. After release, an amendment can be allowed on application within 3 years of acceptance, to let the declarant comply with obligations relating to the procedure (Article 173(3) UCC); Article 174 UCC concerns invalidation of a declaration, not its amendment. In the UK (CDS), a declaration that has not cleared is amended in your software, and after clearance by applying to HMRC within 3 years (C2001 for an underpayment, C285 for an overpayment).
How long should customs documents be kept?
In the EU, customs documentation must be kept for at least 3 years (Article 51 UCC; the period generally runs from the end of the year in which the declaration was accepted), while in the UK HMRC requires it to be kept for 4 years. This obligation applies to commercial invoices, transport documents, customs declarations and proof of payment of import duty and taxes.
Who is liable for errors in a customs declaration?
Responsibility for the content of the declaration lies with the declarant — the importer or their customs representative. Under direct representation, only the importer is liable; under indirect representation, the customs agency is jointly and severally liable with the importer for the accuracy of the data declared.
What are the consequences of filing an incorrect customs declaration?
Filing an incorrect customs declaration can result in customs and tax arrears being assessed together with interest, and fiscal-penal proceedings being opened. In more serious cases, the office can carry out a post-clearance audit (PCA) covering several years back, exposing the company to significant costs.
Can a customs agency correct a declaration without the importer's knowledge?
No. Every correction to a declaration requires the consent and confirmation of the principal — the importer or exporter. A customs agency acts only on a written instruction and cannot independently make changes to a filed declaration without the explicit authorisation of the party it represents.
