Many Dongguan foreign trade owners are confused by duty statements: why do similar products carry different duty rates? Can the amount be reduced? This article explains the calculation logic of US import duty to help you reduce costs compliantly.
How Is US Import Duty Calculated?
US import duty = dutiable value (FOB value + freight + insurance) × applicable rate. There are two core variables:
- HS code classification: different HS codes carry different rates; wrong classification leads to overpayment or underpayment (underpayment carries fine risk);
- Rate structure: most categories use the MFN (most-favored-nation) rate; some categories are affected by additional tariffs.
Duty Filing Process
- Classification and valuation: a professional clearance agent classifies the goods and determines the dutiable value under US customs rules;
- Filing and payment: duty is declared at import entry and can be paid on your behalf by the customs broker;
- Review and refund: overpaid duty can be refunded, and wrong classifications can be corrected within the prescribed period.
Three Compliant Ways to Reduce Duty
- Accurate classification: different codes for similar products carry very different rates, and professional classification avoids overpayment;
- Reasonable valuation: declare at the true transaction price, avoiding over- or under-valuation;
- Use duty-free thresholds: low-value personal items have a minimum exemption; commercial cargo follows trade rules.

Q: Where can I look up US duty rates? A: Search the US HTS database by HS code for rates; a professional forwarder can classify for you and tell you the combined rate (including additional tariffs).
Q: How is duty calculated in FOB vs DDP quotes? A: Under FOB, the buyer pays duty; under DDP, the quote includes estimated duty and the forwarder settles the actual assessed amount with top-up or refund — quoted price equals landed price.
Q: Can I under-declare the value? A: No. Under-declaration is false filing: light cases mean back duty and fines, serious cases affect clearance credit. Compliant filing is the foundation of stable long-term shipping.
Q: When is the duty invoice provided? A: After release, the broker issues the duty statement and payment receipt; DDP customers can verify details against the bill with full traceability.
