A sequence of digits used to identify goods for customs purposes. When trading internationally, you will need to know the correct commodity code for your goods so you can fill out customs paperwork correctly. UK and European Union tariff codes are usually eight digits long for exports and ten digits (or sometimes more) for imports. Most tariff codes globally are based on the Harmonized System of classification, and are often referred to as Harmonized System, or H.S. codes. The harmonized system covers only the first six digits of codes.
