On 26 March 2026, the UK Upper Tribunal issued its judgment in HMRC v. O’Neill Wetsuits Ltd, ruling in favour of HM Revenue & Customs (HMRC) and overturning an earlier decision on the tariff classification of neoprene wetsuits.
The dispute centred on whether wetsuits should be classified as articles of rubber, attracting a 4% duty rate, or as rubberized textile fabrics, subject to a higher 8% rate. The Upper Tribunal concluded that neoprene wetsuits are more appropriately characterized as rubberized textile products, reflecting their composite construction, which typically includes a textile outer layer bonded to cellular rubber.
In reaching its decision, the Tribunal placed emphasis on the essential character and material composition of the goods, as well as the relevant provisions of the UK Global Tariff and applicable classification rules. The judgment confirms that the presence of textile components is not merely incidental but fundamental to the product’s identity and performance.
From a compliance perspective, the ruling has immediate implications for importers and distributors of wetsuits and similar composite goods. Companies should review existing tariff classifications to ensure alignment with the Tribunal’s interpretation, as misclassification may lead to underpayment of duties, retrospective reassessments, and potential penalties.
The decision may also have broader relevance for other products combining rubber and textiles, signalling a stricter approach by HMRC toward substance-based classification analysis.
Businesses should consider conducting classification audits and, where necessary, seek advance rulings to mitigate exposure and ensure consistency in customs declarations.
