How to reduce import duty when importing in the UK
Most UK businesses importing goods are paying more duty than they need to. Not because the rules are unfair, but because the customs procedures that legally reduce, defer, or remove duty liability exist and most businesses either do not know about them or assume they are too complex to access.
The relief schemes covered in this post are not loopholes. They are formal HMRC procedures designed for specific trading situations. Taken together, they represent one of the most underused areas of UK customs law, and one of the most direct routes to reducing an avoidable cost.
Here are the six most common options, who they are designed for, and what accessing them actually involves.
Inward Processing Relief
Suspends import duty and VAT on goods brought in for processing or manufacturing, where the finished product is re-exported.
Customs Warehousing
Defers duty and VAT on goods held in an approved facility until they are released into the UK market or re-exported.
Temporary Admission
Removes duty liability on goods brought into the UK temporarily, where they will leave again in the same or near-same condition.
Outward Processing Relief
Reduces duty when UK goods are sent abroad for processing or repair and returned, so duty only applies to the value added overseas.
Preferential Tariff Rates
Reduced or zero duty rates available under UK trade agreements, based on the origin of the goods rather than where they shipped from.
Duty Drawback
A retrospective claim to recover import duty already paid on goods that were subsequently exported or destroyed.
1. Inward Processing Relief
Inward Processing Relief (IPR) suspends import duty and import VAT on goods brought into the UK for processing, manufacturing, or repair, where the finished product is then re-exported. If you import raw materials or components, process them, and export the output, IPR could eliminate your duty liability on those goods entirely.
The suspension applies for the duration of the authorisation, typically one to three years, and duty only becomes payable if finished goods are sold into the UK market rather than exported. Even then, duty applies only to the proportion entering UK free circulation, not to the whole consignment.
IPR requires an HMRC authorisation and robust record-keeping systems to account for all goods throughout the procedure. Applications go through the Customs Declaration Service. Well-prepared applications typically take eight to twelve weeks.
2. Customs Warehousing
Customs Warehousing allows goods to be stored in an approved facility without paying import duty or VAT until they are released for sale. If your business holds significant stock levels, or imports in bulk but sells gradually, the cash flow benefit alone can be substantial, particularly on high-duty goods.
Duty is only charged when goods leave the warehouse and enter UK free circulation. If goods are re-exported directly from the warehouse, no duty is payable at all. Businesses can also repackage or relabel goods inside a customs warehouse without affecting the duty suspension.
A customs warehouse requires HMRC authorisation and an approved physical location. Businesses can apply to operate their own warehouse or use a third-party approved site.
3. Temporary Admission
Temporary Admission removes duty liability on goods brought into the UK on a temporary basis, where they will be re-exported in the same or near-same condition. It is designed for exhibition samples, professional equipment, goods for demonstration, and items used in events or competitions.
If your business regularly brings goods into the UK for shows, client demonstrations, or testing without the intention of selling them, Temporary Admission is likely to apply and likely to be under-used. It can be accessed through a specific Customs Procedure Code for one-off imports, or through a formal HMRC authorisation for regular use.
The key requirement is that goods must leave the UK by the agreed deadline. Missed re-export dates result in full duty becoming payable immediately.
4. Outward Processing Relief
Outward Processing Relief (OPR) applies when UK goods are sent abroad for processing or repair and then returned to the UK. Without OPR, the returning goods are treated as a new import and duty is charged on their full value. With OPR, duty is only charged on the value added abroad, meaning the processing cost and any additional materials, not the value of the original UK goods.
It is particularly useful for businesses that use overseas manufacturers for specific processes, or that send goods abroad for specialist repair or finishing under warranty arrangements. Like IPR, it requires an HMRC authorisation and clear records linking the exported goods to the returned processed goods.
5. Preferential tariff rates
The UK has trade agreements with a growing number of countries that provide reduced or zero duty rates on qualifying goods. These are called preferential tariff rates and they are based on the origin of goods, not on where the goods were shipped from.
To benefit, goods must meet the rules of origin set out in the relevant trade agreement, and the importer must hold valid proof of origin documentation. Many businesses are importing from countries covered by a UK trade agreement but paying full Most Favoured Nation duty rates because origin has never been checked against the agreement terms.
A structured review of your import commodity codes against your suppliers' countries of origin will quickly identify whether preferential rates apply to goods you are currently paying full duty on.
6. Duty drawback
Duty drawback allows businesses to reclaim import duty already paid on goods that are subsequently exported or destroyed. Unlike the other procedures on this list, it is retrospective rather than prospective. You apply after the fact, not in advance.
If your business paid duty on goods that were later re-exported, you may have a valid drawback claim you have not made. Claims can go back up to three years, which means businesses that have never reviewed their drawback position may have a meaningful sum recoverable right now.
The process involves matching import entries to subsequent export entries and submitting a claim through HMRC. Evidence requirements are strict, so the quality of your original documentation matters.
Which approach is right for your business?
The right option depends on what your business does with the goods. In most cases, more than one procedure applies, and the greatest savings come from combining them. These six questions are a starting point.
If any of these apply to your business and you are not currently using the relevant procedure, there is a good chance you are overpaying.
