By AAT Comment Accountancy resourcesChange of HMRC service for advice on tariff classification10 Jan 2016 Customs duty is usually due when goods are imported into the EU. The rate of customs duty is based mainly on the tariff classification of the goods being imported, although the rate can sometimes be affected by where the goods originate from.Tariff classification is the term used for identifying each specific category of goods. Two examples are sports footwear with outer soles of rubber or plastics, which have a commodity code of 6404110000, and slippers with outer soles of rubber or plastics, which have a commodity code of 6404191000.It should usually be easy to distinguish sports footwear from slippers but there are some goods that it may be difficult to classify correctly. Getting the tariff classification wrong could result in the wrong amount of customs duty being paid and lead to customs back duty demands. HMRC may also impose penalties for incorrect classification.The UK Trade Tariff, which has a search engine and classification guides, can be accessed on the GOV.UK website.
