This is a planning estimate from the US Harmonized Tariff Schedule (revision shown) and the published Federal Register measures as of the date shown, for a shipment of EU origin. It is not a customs entry, legal advice or a broker's opinion, and tariffs.help is not a US-licensed customs broker. The US importer of record or their broker confirms the classification, origin, value and the duty due before filing.

Duty rates shown here are estimates, read from official EU / Danish, Norwegian and UK tariff data for orientation only. Confirm the current rate with Toldstyrelsen, TARIC, Norwegian Customs or the UK Online Trade Tariff before you file. The rate you pay can also depend on the country of origin. These are base customs duties only: import VAT, excise duties, anti-dumping duties and safeguard or quota measures are not included.
