Classifying some difficult goods
If you are having trouble classifying products, you may want to read the plain-English chapter notes for difficult-to-classify commodities. These can be accessed by clicking on the "also on this site" links on the right-hand side of the page.
Binding Tariff classification and other information
If you want an official ruling on the correct commodity code for your goods, you can apply to HM Revenue & Customs (HMRC) for a certification of Binding Tariff Information (BTI). BTI is a written and legally binding decision on a classification code that applies for up to six years from the date of issue. It can help you with particular types of export and complying with rules of origin.
