Found a discrepancy, spotted a missing measure, or have an idea for a tool we should build? We read every message, and corrections to data are handled first.

Send us a message

Used only to reply to you.

Speeds up a data correction considerably.

Sending opens your email application with the message pre-filled. For urgent customs matters, contact HMRC directly — we are not a government service and cannot give binding rulings.

Before you write

Data corrections

Include the commodity code, the figure you believe is wrong, and where possible a link to the official source you consider authoritative. Corrections are normally actioned within a few working days.

Classification advice

We cannot give binding classification rulings. For a legally binding decision, apply to HMRC for a Binding Tariff Information (BTI) ruling, or instruct a customs agent.

Tool suggestions

Tell us what you were trying to work out and what you had to do instead. Concrete problems shape the roadmap far better than feature lists.
