PAS 41201:2026 takes effect 30 June 2026
The customs intermediary standard is here. Find out where you stand.
PAS 41201 sets 61 requirements for how intermediaries prepare and submit customs declarations: internal audit, due diligence, training, systems and transparency. Our free gap assessment walks you through every one, clause by clause, and gives you a report you can put in front of your board.
What PAS 41201 is.
PAS 41201:2026 is the Voluntary Standard for Customs Intermediaries: sponsored by HMRC, published by BSI on 3 June 2026, in effect from 30 June 2026. It applies at the level of the organisation, not the individual, and covers customs agents, freight forwarders, express operators, warehouse operators and hauliers who prepare or submit declarations on behalf of others. Around 78% of all UK customs declarations are filed by an intermediary, so most of the sector is in scope.
The standard is voluntary, but it is written for independent third-party certification by UKAS-accredited bodies, and UKAS sat on the steering group. Clauses 4 to 9 contain 61 normative requirements covering internal audit, client relationships, due diligence, operational resilience, training and competence, systems and processes, and transparency with the businesses you represent.
This is not a one-off project.
Many of the 61 requirements are recurring obligations with defined frequencies and six-year retention periods. Conformity means running a cycle, not filling in a form once. The main recurring commitments:
Quarterly declaration audits
Audit your submitted declarations every quarter on a minimum 5% random sample (up to 25,000 declarations), including high-risk and licensed goods. Document the results, tell affected clients within a month, and correct your own errors within 90 days at no charge.
Annual cycles
An annual audit of your systems and processes, an annual review of due diligence procedures, annual employee reviews with CPD evidence, annual suspicious-activity training, and annual SOP reviews with version control.
Six-year records
Appointment evidence, due diligence records, MRN confirmations, complaints and client data files all carry six-year retention requirements, most running from the date of the last declaration.
The gap assessment: 61 requirements, one private link.
Start with your company name and email
No account, no password. You get a private link to your assessment; we email it to you so you can come back to it any time, from any device.
Work through the requirements, clause by clause
Each requirement comes with plain-English guidance on what good evidence looks like, the recurrence frequency, and the retention period. Mark each one met, in progress, not started or not applicable. Everything saves as you go.
Get your gap report
A clause-by-clause readiness summary with your gap list in priority order, printable and ready for your board or your certification planning.
The hardest requirement is clause 4.2. We built the tool for it.
For a mid-size intermediary, a quarterly 5% sample is thousands of declarations checked against supporting documentation, four times a year, documented. Done manually, that is weeks of spreadsheet work per quarter. CAT360 ingests your own CDS reports and runs that review across your whole book, every declaration rather than a sample, and produces the documented record the standard asks for.
Questions
Is PAS 41201 mandatory?
No, it is voluntary. But it is HMRC-sponsored, written for UKAS-accredited certification, and intermediaries are already being asked about it by clients. The practical question is not whether you must conform, but whether you can afford to be the firm that cannot show it.
Who is in scope?
Any organisation that prepares or submits customs declarations on behalf of another business: customs agents, freight forwarders, express operators, customs warehouse operators and hauliers. The requirements apply to the organisation, not to individual employees.
Can I get certified today?
Not yet. Certification bodies still need UKAS accreditation, so the sector is in the preparation phase. That is exactly when a gap assessment is most useful: you find out what to fix while there is still time to fix it.
Is the gap assessment really free?
Yes. No account, no card, no obligation. We built it because we work with intermediaries every day and they kept asking the same question: where do we stand?
Where do I get the standard itself?
From BSI. The requirement statements in our assessment are paraphrased for self-assessment and are not a substitute for the standard, which remains the authoritative text.
Who built this?
Barbourne Brook, the customs consultancy behind CAT360. We review customs declarations at scale for a living; the assessment encodes how we run readiness engagements.
30 June is closer than it looks.
