The standard is voluntary. Proving you meet it isn't optional.
Compliance with PAS 41201 is self-declared — and it must be provable when principals ask. BorderAudit produces the documented §4.2 audit evidence that answers them: sampled declaration review, findings, corrective actions and locked records.
What the customs intermediaries voluntary standard expects.
PAS 41201 is a voluntary specification — a Publicly Available Specification (PAS) — for organisations that prepare and submit customs declarations on behalf of others, published by BSI (the British Standards Institution) on 2 June 2026 with HMRC's support. Most of it is about how you run your practice. One clause is about proof.
A documented internal audit, at least annually, of your own submitted declarations — sampling the Annex A data fields — with principal notification and agreed corrective action within one month where someone was negatively impacted, and findings reported to management.
What the clause expects. What the platform evidences.
BorderAudit doesn't certify you against the standard — BSI owns it, and the declaration of conformance is yours. What the platform does is produce the evidence behind that declaration, requirement by requirement.
A documented internal audit, at least annually, of the declarations you have submitted on behalf of principals.
A documented, sampled, field-level review of your own declaration book — the same post-clearance audit engine, pointed at the entries you submitted.
Sampling across the standard's data fields — classification, origin, preference, valuation and procedure codes.
The same dimensions BorderAudit already analyses on every entry, so each sampled declaration is checked field by field, automatically.
A self-declaration of compliance that holds up when a principal asks how you meet the requirement.
Sampling records, categorised findings, corrective actions and retained reports — the evidence trail behind your declaration of conformance.
Where an audit shows a principal was negatively impacted: inform them and agree corrective action within one month.
A findings-to-remediation workflow built for exactly that loop — notification, agreed corrective action, and a record that both happened.
Audit records you can stand behind — retained, reported to the relevant managers, and safe from quiet revision.
Audit records are locked at submission. Findings are immutable from that moment, giving you a clean trail for conformance evidence.
