EXPERT HELP WITH CUSTOMS DUTY

Talk to our specialist team

Post-Brexit, access to UK customs duty advice and services has never been more important. The customs area can be complex with a diverse range of reliefs and regimes available to businesses, such as:

Authorised Economic Operator (AEO)
Inward/Outward Processing
Customs Warehousing
Authorised Use
International Trade Compliance (e.g. Export Licensing)

Unlike VAT, customs duty is not normally recoverable, so the cost has to be built into your pricing as it may impact your profitability and competitiveness. We offer advice and support in all areas of international trade, highlighting which duty reliefs and/or regimes may be available to you.

Our customs duty services include:

DUTY RECLAIMS

t is not unusual for importers to overpay UK customs Duty. This could be because of incorrect tariff classification, failure to claim a preferential rate of duty or incorrect application of a customs relief. In addition, duty paid through the TSS system on goods wrongly declared “at risk” is recoverable by taxpayers.

AAB can support businesses with the identification and submission of claims for overpaid duty. We have developed a robust approach which maximises results whilst minimising the disruption to businesses.

Where we identify that customs duties have been overpaid, we prepare and submit the necessary claim to HMRC for a refund of the amount due.

The customs regulations enable businesses to recover any overpayments of customs duty going back up to three years. Furthermore, most customs duty relief schemes have the option of retrospective approval going back up to 12 months.

Any claim will need to be accompanied by the necessary supporting evidence.

Importantly, these projects can be carried out on a no-win-no-fee basis. As a result, there is no downside as any fee due will only be payable when the refund is received by the business.

TRADING WITH THE USA: WHAT YOU NEED TO KNOW

Trading with the US has never been more complex. Whether on a B2B or B2C basis, there are a range of additional considerations to take into account.

If you’re importing goods from the US, understanding your UK import UK obligations is key. You may need to factor in UK import duties, and other specific UK customs charges that apply depending on the type and value of goods.

If exporting to the US, the position is similar; however, there may be a need to factor in additional and variable tariffs depending upon the origin, composition or nature of your goods.

We help you determine:

the correct HS tariff code,
the appropriate Customs valuation
the origin of the goods.

This allows you to accurately calculate your import duty liability, and ensure your documentation is in order. Our team ensures your goods move efficiently through UK and US custom clearance;, avoiding delays and unexpected costs.

Need to clarify your customs tariff responsibilities or reclaim duties already paid? We’ll support you every step of the way.
