§ FAQFrequently asked
- What is the general MFN duty rate for HTS 0303?
- HTS 0303 (Fish, frozen, excluding fish fillets and other fish meat of heading 0304) is a heading-level row and carries no MFN rate of its own; the base rate is set on each subheading beneath it (see the subheading list on this page). This applies to imports from countries with normal trade relations status. For origins like China, additional Section 301, IEEPA, and reciprocal duties may stack on top of this base rate. Final duty is determined at CBP entry.
- Are there active Chapter 99 tariff overlays on HTS 0303?
- Yes. For China origin, 1 active Chapter 99 rule(s) currently stack on HTS 0303: Section 301 forced-labor action (China). Overlays apply by country of origin and effective date, and a single shipment can be subject to several at once — verify the current list against your classification before ordering.
- What's the total US import duty for HTS 0303 from China today?
- HTS 0303 is a heading-level row whose MFN base rate is set per subheading, so this page cannot state a complete total. The Chapter 99 overlays currently in force for China origin alone add about $1250.00 on a $10,000 customs value (~12.50%); the full duty is the subheading's MFN rate plus that stack. Actual duty is determined by CBP at entry based on classification, valuation, and rules in effect on the entry date.
- When was HTS 0303 last updated on Duty?
- The base HTS data on this page was last refreshed on September 8, 2026 (USITC release 2026HTSRev18). Chapter 99 overlays, AD/CVD case status, and Federal Register notices are synced daily; effective dates follow the source feeds.
