Commodity codes classify goods for import and export. Knowing the correct commodity code for goods is required for filling in declarations and other paperwork. Commodity codes also define the duty and VAT rates you’ll be charged for your goods. Beside that they tell you if you can apply for preferential duty rating, or if your products are subject to any restrictions. The Trade Tariff Tool can be used to find commodity codes. As from January 1, 2021, the UK Global Tariff will apply to imports to the UK.
