HMRC’s Advance Valuation Ruling Service (“AVRS”) is a significant development in the United Kingdom’s post-Brexit customs regime. Introduced in April 2023, it enables importers to obtain a legally binding ruling in advance on the correct customs valuation method for specified goods and a defined factual scenario.

That matters because customs valuation is not a mere accounting exercise. It determines the basis on which ad valorem Customs Duty is charged and also affects import VAT. Where the valuation analysis is wrong, businesses may face assessments for underpaid duty and VAT, interest, penalties and protracted dispute with HMRC.

The AVRS should therefore be understood not simply as a new administrative service, but as a legal and risk-management tool within the statutory architecture of UK customs law.

The statutory framework

The primary domestic legislation is the Taxation (Cross-border Trade) Act 2018 (“TCTA 2018”). Section 16 provides the statutory basis for determining the customs value of chargeable goods.

The detailed rules are contained in Part 12 of the Customs (Import Duty) (EU Exit) Regulations 2018, SI 2018/1248. That statutory instrument is central. It sets out the valuation methods and the rules governing additions to, and exclusions from, the price paid or payable. It includes provisions dealing with matters such as commissions, brokerage, assists, royalties and licence fees, transport, insurance and other elements which may need to be included or excluded in determining customs value.

The distinction matters. HMRC guidance is important in practice, but it is not the source of the legal rules. The starting point remains the Act and the statutory instrument.

The WTO framework

The UK regime also reflects the structure of the WTO Agreement on Implementation of Article VII of the General Agreement on Tariffs and Trade 1994, commonly referred to as the WTO Customs Valuation Agreement.

The WTO framework treats transaction value as the primary basis for customs value. That is the price actually paid or payable for the goods when sold for export to the country of importation, adjusted where appropriate. Where transaction value cannot be used, the Agreement provides a sequence of alternative valuation methods.

That international framework explains the structure of UK customs valuation law. Method 1, transaction value, is the first method to be considered. If it cannot properly be applied, the analysis moves through the alternative methods in sequence. It also explains why valuation disputes often turn not on arithmetic, but on legal characterisation: what was sold, by whom, to whom, for what price, and subject to what other payments or conditions.

The legal basis for Advance Valuation Rulings

The statutory basis for the AVRS is found in section 24 TCTA 2018, as amended by section 317 of the Finance (No. 2) Act 2023. Section 24 originally concerned advance rulings on tariff classification and origin. The 2023 amendment extended HMRC’s advance ruling powers so that they also cover the valuation method to be used in determining the value of goods.

That amendment is important. It places valuation alongside classification and origin as an area in which traders may obtain advance legal certainty before importation. For businesses importing goods regularly, or operating through complex supply chains, that is a valuable addition to the customs compliance toolkit.

An Advance Valuation Ruling is a written decision issued by HMRC at the request of the importer. HMRC states that it is legally binding on both HMRC and the applicant for the specified goods and factual scenario, generally for three years unless withdrawn or cancelled.

What an AVR does and what it does not do

An AVR confirms the valuation method to be used. It does not certify that every figure ultimately inserted into a customs declaration is correct.

That distinction is important. A ruling may confirm, for example, that Method 1 is available, or that another valuation method must be used. The importer must still calculate the actual customs value correctly, ensure that any additions or exclusions are properly made, and retain evidence supporting the declaration.

Nor is an AVR retrospective. The application must be made before the relevant import declaration is made or before the relevant customs procedure has been completed. It is a prospective compliance tool, not a cure for historic under-declarations.

Why valuation disputes arise

Customs valuation disputes frequently arise because the invoice price does not answer all the legal questions. Issues may include:

• Which sale is the relevant sale for import;
• Whether the buyer and seller are related;
• Whether the transaction value is acceptable;
• Whether royalties or licence fees must be added;
• Whether commissions are buying commissions or dutiable selling commissions;
• Whether assists have been supplied free of charge or at reduced cost;
• Whether post-import price adjustments affect the customs value; and
• Whether the declared price reflects the correct legal value of the imported goods.

The case law illustrates how easily valuation issues can become legally and evidentially complex.

HMRC v Asda Stores Ltd: identifying the relevant payment

In HMRC v Asda Stores Ltd [2013] UKUT 0223 (TCC), the Upper Tribunal considered customs value under Articles 29 and 32 of the Community Customs Code. The dispute arose in the context of imported clothing and related hanger arrangements. Asda argued, in substance, that rebates received from hanger suppliers should reduce the customs value.

The Upper Tribunal rejected that argument under Article 29. The relevant price paid or payable was the total payment made by Asda to the clothing suppliers. The rebates received from the hanger suppliers could not be taken into account under Article 29 because they did not alter the amount paid by Asda to the sellers of the imported goods.

The case is a useful reminder that customs value depends on identifying the legally relevant buyer, seller and payment. A commercial sense that the importer’s net economic cost is lower will not necessarily reduce the customs value if the statutory conditions are not met.

Club 21: buying commissions and evidence

Club 21 (UK) Ltd v HMRC [2014] UKFTT 1113 (TC) concerned whether amounts said to represent buying commission and other charges could be excluded from customs value. The First-tier Tribunal dismissed the appeal.

The case is useful because it illustrates the evidential burden on an importer seeking to exclude an alleged buying commission from customs value. A payment will not be excluded merely because it is labelled a commission, or because the parties describe an intermediary as an agent. The tribunal will look at the contractual structure, the commercial reality and the evidence.

For importers considering an AVR, the point is clear. The application should be supported by proper documentation. Contracts, invoices, purchase orders, agency agreements, royalty agreements and transfer pricing materials may all matter. A bare assertion about how a payment should be characterised is unlikely to be enough.

GE Healthcare: royalties and licence fees

GE Healthcare GmbH v Hauptzollamt Düsseldorf, Case C-173/15, is relevant where royalties or licence fees may be connected with imported goods.

The case supports the careful proposition that payments outside the invoice price may still be relevant to customs value where the legal conditions are met. In particular, the Court considered the treatment of royalties or licence fees which related to the goods being valued, including circumstances where the royalties related only partly to those goods.

For UK importers, royalties remain an area where advance analysis is particularly important. If a royalty or licence fee is wrongly excluded from customs value, the resulting duty exposure may be significant.

Hamamatsu: transfer pricing adjustments

Hamamatsu Photonics Deutschland GmbH, Case C-529/16, remains an important authority on the tension between customs valuation and transfer pricing.

The case concerned intra-group pricing and subsequent adjustment. The Court held that the customs rules in issue did not permit a transaction value made up of an initially invoiced amount and a flat-rate adjustment made after the end of the accounting period, where it was not possible to know at the time of import whether that later adjustment would be upwards or downwards.

The case is particularly relevant to related-party importers. Transfer pricing and customs valuation are related, but they are not the same discipline. A year-end transfer pricing adjustment may be relevant for direct tax purposes, but it does not automatically determine the customs value of goods at import.

Baltic Master: related parties and doubts about declared value

Baltic Master UAB, Case C-599/20, is relevant to related-party valuation and the scrutiny customs authorities may apply where the declared transaction value is open to doubt.

The case should not be overstated. It does not mean that related-party transaction values are inherently unacceptable. Rather, it illustrates the need for objective evidence where the relationship between parties, or the circumstances of the transaction, gives rise to questions about whether the declared value is acceptable.

For importers, the practical lesson is that related-party pricing should be documented. The importer should be able to explain why the relationship has not influenced the price, or otherwise justify the valuation method used.

The post-Brexit status of EU authorities

Some leading customs valuation authorities arise from the former EU customs regime. They must therefore be used with care in the UK’s post-Brexit legal order.

Nevertheless, they remain useful where they address concepts that have been carried through into the UK framework, including transaction value, additions to price, related-party transactions, royalties and the sequential use of valuation methods. Their precise status will depend on the date of importation, the applicable legislation and the rules on retained or assimilated EU case law under the European Union (Withdrawal) Act 2018.

For a UK legal analysis, the safer approach is not to treat CJEU authorities as automatically determinative in every post-Brexit dispute, but to use them carefully where they illuminate concepts reflected in the domestic regime.

Practical implications for importers

The AVRS is likely to be most useful where valuation is legally or commercially sensitive. That includes cases involving:

• related-party sales;
• transfer pricing adjustments;
• royalties or licence fees;
• buying commissions or selling commissions;
• assists;
• multi-party supply chains;
• uncertainty over the relevant sale for import;
• recurring imports of high-value goods; and
• circumstances where Method 1 may not be available.

In those situations, an AVR may provide significant protection. It can assist with customs compliance, budgeting, audit preparedness and communications with brokers. It may also reduce the risk of HMRC later challenging the valuation method used.

However, the quality of the ruling will depend on the quality of the application. The applicant should identify the goods, describe the transaction accurately, explain the proposed valuation method and provide supporting evidence. If the facts are incomplete or later change, the ruling may offer limited protection.

Conclusion

The Advance Valuation Ruling Service is a welcome development in UK customs law. It provides importers with a route to legal certainty on valuation method before goods are imported.

Its significance lies in the statutory framework behind it. Section 16 TCTA 2018 supplies the foundation for customs value. Part 12 of the Customs (Import Duty) (EU Exit) Regulations 2018, SI 2018/1248, contains the detailed valuation rules. Section 24 TCTA 2018, as amended by section 317 of the Finance (No. 2) Act 2023, now enables HMRC to issue advance rulings on valuation method.

The case law demonstrates why this matters. Customs valuation disputes turn on legal characterisation, evidence and statutory method. The correct answer may depend on identifying the relevant sale, the relevant payment, the role of an intermediary, the treatment of royalties, or the effect of related-party pricing.

For importers, the message is straightforward: customs valuation should be analysed before goods are declared, not after HMRC raises questions. Where the method is uncertain, material or likely to recur, an Advance Valuation Ruling may be an important part of a defensible customs strategy. It is not, however, a substitute for careful legal analysis, proper evidence and accurate implementation.
