US imports under HTS 0304 at a glance
Between March and July 2026, US importers entered $2.53 billion of fish fillets and other fish meat, fresh, chilled or frozen under HTS heading 0304, from 41 of the 55 origin countries covered here and across 119 ten-digit tariff lines — roughly $505 million a month of customs value under a single four-digit heading.
Chapter 03 covers fish, crustaceans and molluscs; heading 0304 is one of its larger entries by value, which is why the duty treatment below is worth checking line by line.

Who exports fish fillets and other fish meat, fresh, chilled or frozen to the United States
Chile is the largest origin with $984 million, or 38.9% of the heading, with China at 13.3% and Vietnam at 12.7%. The top three take 65% between them — enough concentration to matter when one origin's duty treatment changes, but not so much that a buyer has no alternative to qualify.
Canada sits near the top of the table, and the duty numbers reflect it: Canada entered 99.6% of its value free of duty. Cargo that qualifies under USMCA and is claimed correctly at entry pays nothing; cargo that does not qualify, or that is never claimed, pays the ordinary rate. The certification is the whole difference.
What importers actually paid in duty
Almost everything under this heading is dutiable: 90.7% of entered value carried duty, and CBP collected $237 million over the five months. The effective rate on dutiable value was 10.3%, which works out to $9.37 of duty per $100 of goods. There is no meaningful duty-free channel here — classification and origin are the only levers.
The spread between origins is real. Among origins with at least 2% of the heading, China paid the most duty relative to value — $14.41 per $100 — while Canada paid $0.04. On a $250,000 purchase order that gap is about $36,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 0304
119 ten-digit lines carried trade under this heading in the period. The largest, 0304.41.00.10 (pacific salmon Atlantic Salmon and Danube salmon), took 30% of the heading at $757 million. 0304.81.50.10, 0304.89.50.91 and 0304.71.50.00 follow. Rates diverge between those lines, so the classification your broker files is worth checking against the goods rather than carried over from the last entry.
What the duty stack looks like
The rate on an entry is not one number. It is a stack: the general (column 1) rate for the 10-digit line, less any trade-agreement preference the goods qualify for, plus whatever additional duties apply to that product and origin, all applied to the customs value declared. The $9.37 per $100 above is what that stack averaged across every entry in this heading — a benchmark, not a quote.
For the origins carrying the most volume, the per-country breakdowns go a level deeper: Chile (0304.41.00), China (0304.71.50) and Vietnam (0304.62.00). To price a specific shipment, put your 10-digit code and country of origin into the tariff simulator.
What this means for your next shipment
The practical sequence is: confirm the 10-digit line against the actual goods, confirm origin under the substantial-transformation rules rather than the shipping address, then price the duty on that pair. Airlift USA moves the cargo and coordinates classification and entry filing through our licensed broker network, so the code agreed at booking is the one on the entry.
For the operational side rather than the tariff side, see the Refrigerated & Perishable Commodities guide for how this cargo moves, the China to USA lane for transit times and ports and the heading index to compare against the rest of chapter 03.

Methodology
Figures come from the U.S. Census Bureau's international trade statistics for imports for consumption — the customs value of goods entered into US commerce, not shipments in transit or goods held in bonded warehouses. The period is March–July 2026 (5 months of data), and coverage is limited to 55 major origin countries, so totals here are lower than published US-wide totals for the same heading.
Three quantities are additive and everything else is derived from them: entered customs value, dutiable value and calculated duty. Effective duty is calculated duty divided by dutiable value — the rate CBP actually applied to the part of the trade that was dutiable. Dutiable share is dutiable value divided by entered value; below 20% it means the trade entered mostly free, under a trade agreement or a duty-free provision. Duty per $100 spreads calculated duty across all entered value, which is the figure comparable between origins.
Chapter 98 and chapter 99 are excluded: those are special classification and temporary-measure provisions rather than product headings. Heading and tariff-line descriptions are the current HTS text. Values are historical and reflect duty as calculated at the time of entry; they are not a quote and not a prediction of the rate on a future shipment.

Frequently asked questions
Which countries export the most fish fillets and other fish meat, fresh, chilled or frozen to the United States?
Chile is the largest origin under HTS heading 0304, with $984 million entered between March and July 2026, or 38.9% of the heading. China follows at 13.3% and Vietnam at 12.7%. Figures cover the 55 major origin countries in this dataset. Source: U.S. Census Bureau, USA Trade Online / International Trade API, imports for consumption, March–July 2026; effective duty = calculated duty ÷ dutiable value.
How much import duty is paid on fish fillets and other fish meat, fresh, chilled or frozen under HTS 0304?
Across all origins, 90.7% of the entered value was dutiable and CBP calculated $237 million of duty over the five months — an effective 10.3% on dutiable value, or about $9.37 per $100 of goods across the whole heading. Your own rate depends on the exact 10-digit line and country of origin.
Which HTS codes fall under heading 0304?
Heading 0304 covers fish fillets and other fish meat (whether or not minced), fresh, chilled or frozen. 119 ten-digit lines recorded imports in this period; the largest by value were 0304.41.00.10, 0304.81.50.10, 0304.89.50.91 and 0304.71.50.00. Duty rates differ between those lines, so the 10-digit classification matters more than the heading.
Which origin pays the lowest duty on fish fillets and other fish meat, fresh, chilled or frozen?
Among origins with at least 2% of the heading, Canada paid the least duty relative to entered value — about $0.04 per $100 of goods, with 99.6% of its value entering free. Duty is only one part of landed cost, and a claim has to be substantiated at entry to be allowed.
