HMRC Proposes Mandatory Registration for Customs Intermediaries: What Businesses Need to Know
HMRC has launched a consultation on the introduction of mandatory registration for customs intermediaries (CI). If implemented, this would represent one of the most significant changes to the customs intermediary sector since the UK’s departure from the EU.
The proposal aims to ensure that businesses using customs agents, brokers and freight forwarders can have greater confidence that their intermediary meets minimum compliance standards and is subject to ongoing oversight by HMRC.
What is being proposed?
Currently, there is no mandatory registration scheme for customs intermediaries operating in the UK. HMRC is proposing that all businesses submitting customs declarations on behalf of traders must register before they can provide these services.
To register, intermediaries would need to show they meet suitability and compliance requirements, including maintaining compliant tax affairs and avoiding serious customs compliance issues.
As part of the consultation, HMRC is also proposing ongoing monitoring, with enforcement powers ranging from warnings and improvement notices through to suspension or removal from the register where standards are not maintained.
Why is HMRC introducing this?
The consultation follows the recent publication of PAS 41201, the voluntary best practice standard for customs intermediaries.
While PAS 41201 encourages higher professional standards across the industry, the proposed registration scheme would establish a mandatory minimum level of competence and compliance for all customs intermediaries.
The objective is to:
- Improve the quality and accuracy of customs declarations
- Increase confidence in customs intermediaries
- Reduce errors and non-compliance
- Create a level playing field across the customs sector
- Protect businesses from poor-quality customs services.
What does this mean for importers and exporters?
Although the proposal is aimed at customs intermediaries, it is likely to benefit businesses that rely on external customs agents.
Potential benefits include:
- Greater assurance that your customs intermediary meets HMRC’s minimum standards
- Improved consistency and quality of customs declarations
- Reduced risk of errors that could lead to delays, additional duty or penalties
- Increased transparency and accountability within the customs intermediary sector.
However, it is important to remember that the legal responsibility for customs declarations ultimately remains with the importer or exporter, even where an intermediary submits declarations on your behalf.
What should businesses do now?
The consultation is still open, so no changes have yet been introduced. However, now is a good opportunity to review your current customs arrangements.
You may wish to ask your customs intermediary:
- Are you preparing for mandatory registration?
- How do you ensure ongoing compliance with HMRC requirements?
- What quality assurance processes do you have in place for customs declarations?
- Are you aligned with the PAS 41201 voluntary standard?
Businesses should also continue carrying out appropriate due diligence when selecting customs intermediaries and ensure that responsibilities are clearly documented.
Final thoughts
The introduction of mandatory registration would represent a significant step towards professionalising the UK CI sector. Combined with PAS 41201, it would create a framework that sets both mandatory minimum requirements and recognised best practice.
For businesses involved in international trade, choosing a competent CI has never been more important. Understanding these proposed changes now will help you prepare for any future regulatory developments and ensure your customs compliance remains robust.
