Why customs matter to a first-time founder
Customs controls goods crossing a jurisdiction’s border. Getting the commodity code, origin, value, documents, and responsible importer wrong can delay a shipment, increase duty, or cause penalties and seizure. A courier or customs broker can submit declarations, but the business may still remain legally responsible for the information supplied and the records kept.
Examples of customs
A UK company imports 1,000 lamps from Vietnam for £20,000. Before shipment, it identifies the commodity code, checks origin evidence and product restrictions, and estimates import duty and VAT. Its broker files the declaration, but the company keeps the invoice and classification support. A wrong code could change the duty and hold the goods at the border.
Common misunderstanding
Customs duty is not the same as import VAT, freight charges, or a tariff schedule, although several amounts may be collected together. Customs rules are jurisdiction-specific and depend on the goods, origin, destination, value, and procedure used. Membership of a customs union may remove some internal duties, but it does not remove every declaration, tax, safety, or product requirement.
When to use it
Check customs before pricing or shipping physical goods across a border, including samples, returns, repairs, and online orders. Confirm who is the importer or exporter of record and which Incoterm the contract uses. Use the official authority or a qualified broker for the route involved. Do not rely on another country’s calculation or an old shipment with different facts.
