HMRC has released updated guidance on how importers can amend or cancel declarations submitted via the Customs Declaration Service (CDS), the UK's post-Brexit customs system. The guidance, published 16 June 2026, sets out the rules, timelines, and documentation requirements for both amendments and cancellations.
Who can amend or cancel
The guidance specifies that declarants registered with CDS can request amendments to import declarations after submission but before goods are released, or cancellations in defined circumstances. HMRC notes that not all declarations are eligible for amendment or cancellation—certain conditions must be met and specific timeframes apply.
The amendment and cancellation process
According to HMRC:
Check if you can amend or cancel your import declaration and what you need to do to make an amendment or request a cancellation.
Importers must verify eligibility before submitting requests. The guidance covers:
- Amendments: corrections to declaration data (commodity classification, value, origin, etc.) before goods are cleared or released.
- Cancellations: requests to withdraw a declaration entirely, subject to HMRC approval and timing constraints.
- Required documentation: supporting evidence for amendments (invoices, certificates of origin, corrected HS codes) and justification for cancellations.
Declarants should use the CDS portal to submit amendment or cancellation requests and track status through their account.
Timeline and practical impact
The guidance emphasises that amendments are faster and cheaper than waiting for goods to be rejected or detained due to declaration errors. Cancellations may incur administrative fees if submitted after a certain point in clearance.
Importers who discover errors in duty classification, consignee details, weight, or Intrastat reporting should flag them immediately. Delayed amendments risk delays, penalties, or seizure of goods.
What this means for shippers
Review your recent CDS declarations now. If you've spotted errors in HS codes, declared value, or origin country, submit amendment requests immediately—don't wait for HMRC to flag them. Check the CDS portal for your declaration status and the window for amendment eligibility. Amending proactively is faster and cheaper than disputing a duty assessment after release.
