Incoterms are the International Chamber of Commerce rules that set who pays for freight, insurance and duty in a sale. They matter for customs because the U.S. charges duty on a value that excludes international freight and insurance. If your price includes those costs, as a CIF or DDP price does, they have to be taken out before the value is declared. If they are not, you pay duty on shipping.
Deductions must be supported by documents, such as freight invoices or a breakdown on the commercial invoice. Estimates without support are not accepted.
Is the value on my invoice always the value I declare? Not always. See dutiable value.
Can I fix past overvaluation? Yes, by PSC before liquidation or by protest within 180 days after. See PSCs and protests.
Caspian compares entered values against Incoterms and freight records to find duty paid on shipping. See our trade audit.
