HMRC Removes Obsolete CHIEF References from Customs-Debt Procedures

Summary

• HMRC has removed guidance concerning declarations made through CHIEF because the legacy customs system is no longer in use.
• Current customs-debt and voluntary-disclosure procedures are now framed around the Customs Declaration Service.
• Importers should update customs procedures, broker instructions, disclosure templates and training materials that still contain CHIEF terminology.

HMRC updated its customs-debt guidance on 13 August 2026 by removing information relating to declarations made through the Customs Handling of Import and Export Freight system, commonly known as CHIEF.

The corresponding GOV.UK alert states that the information was removed because CHIEF is no longer in use. Update from GOV.UK for: Customs debt liability [Update fro…liability | Outlook], [Update fro…liability | Outlook]

HMRC defines a customs debt as an amount owed for import or export duties. The published guidance expressly includes import VAT among the potential import liabilities. It also covers customs-debt notifications, voluntary disclosures, interest and the parties who may be responsible for the debt.

For imports declared through the Customs Declaration Service, businesses and their representatives can make a voluntary disclosure where they identify an underpayment of customs duty or import VAT. The related voluntary-clearance-amendment page was also updated on 13 August 2026 to remove CHIEF instructions and obsolete CDS postal-form references.

This is primarily a procedural clean-up rather than a new tax charge. Nevertheless, it has a direct compliance impact where internal documentation still tells users to:

• retrieve CHIEF entries;
• quote obsolete CHIEF references;
• use CHIEF-specific amendment forms;
• follow legacy post-entry amendment steps; or
• request evidence from customs agents using outdated terminology.

Importers should review standard operating procedures, customs-agent instructions, post-entry testing controls and voluntary-disclosure templates. Evidence requirements should be aligned with CDS data, including the Movement Reference Number, commodity code, procedure code and details of the amendment.

Where postponed VAT accounting was used, HMRC’s voluntary-clearance guidance states that underpaid import VAT should be accounted for on the VAT return rather than through the customs underpayment service.
