US imports under HTS 4703 at a glance
Between March and July 2026, US importers entered $1.25 billion of chemical woodpulp, soda or sulfate under HTS heading 4703, from 9 of the 55 origin countries covered here and across 6 ten-digit tariff lines — roughly $249 million a month of customs value under a single four-digit heading.
Heading 4703 sits in chapter 47, wood pulp and recovered paper, so anything classified here shares a duty structure with the rest of that chapter.

Who exports chemical woodpulp, soda or sulfate to the United States
Brazil, Canada and Sweden together account for 94.8% of the heading. Brazil leads with $553 million (44.3%), ahead of Canada at 40.8% and Sweden at 9.7%. Concentrated but not captive: alternatives exist, and buyers who qualify a second origin early keep some leverage when duties move.
Canada sits near the top of the table, and the duty numbers reflect it: Canada entered 100% 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
Most of this heading enters duty-free. Only 0.4% of the entered value was dutiable, and across all origins CBP collected $302,000 — about $0.02 of duty per $100 of goods. The headline rate on the dutiable portion was 6.1%, but it applies to a small slice, so the number that matters to a landed-cost model is the $0.02.
Duty treatment is fairly uniform across origins here: the countries with real volume all land within a narrow band of $0.00–$0.01 per $100 of goods. Where that happens, switching origin does little for the duty bill, and savings have to come from classification, valuation or freight.

The 10-digit lines under heading 4703
6 ten-digit lines carried trade under this heading in the period. The largest, 4703.21.00.40 (bleached), took 48.9% of the heading at $610 million. 4703.29.00.40, 4703.11.00.00 and 4703.29.00.20 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 $0.02 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: Brazil (4703.29.00), Sweden (4703.21.00) and Finland (4703.21.00). 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
Classify first, confirm origin second, quote freight third. A heading like 4703 rewards that order, because the duty differences between lines and between origins are usually larger than the freight differences on the same lane. Airlift USA handles the freight and coordinates classification and entry through our licensed broker network.
For the operational side rather than the tariff side, see the Paper Packaging & Materials Commodities guide for how this cargo moves, the Brazil to USA lane for transit times and ports and the heading index to compare against the rest of chapter 47.

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 chemical woodpulp, soda or sulfate to the United States?
Brazil is the largest origin under HTS heading 4703, with $553 million entered between March and July 2026, or 44.3% of the heading. Canada follows at 40.8% and Sweden at 9.7%. 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 chemical woodpulp, soda or sulfate under HTS 4703?
Across all origins, 0.4% of the entered value was dutiable and CBP calculated $302,000 of duty over the five months — an effective 6.1% on dutiable value, or about $0.02 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 4703?
Heading 4703 covers chemical woodpulp, soda or sulfate, other than dissolving grades. 6 ten-digit lines recorded imports in this period; the largest by value were 4703.21.00.40, 4703.29.00.40, 4703.11.00.00 and 4703.29.00.20. Duty rates differ between those lines, so the 10-digit classification matters more than the heading.
Which origin pays the lowest duty on chemical woodpulp, soda or sulfate?
Among origins with at least 2% of the heading, Canada paid the least duty relative to entered value — about $0.00 per $100 of goods, with 100% 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.
How do I check the duty on my own shipment?
