US imports of Organo-sulfur compounds

US imports under HTS 2930 at a glance

Between March and July 2026, US importers entered $573 million of organo-sulfur compounds under HTS heading 2930, from 27 of the 55 origin countries covered here and across 34 ten-digit tariff lines — roughly $115 million a month of customs value under a single four-digit heading.

Heading 2930 sits in chapter 29, organic chemicals, so anything classified here shares a duty structure with the rest of that chapter.

Who exports organo-sulfur compounds to the United States

Switzerland is the largest origin with $206 million, or 36% of the heading, with China at 17.9% and Spain at 11.6%. The top three take 65.5% 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.

European origins account for 28.8% of the heading, led by Spain, Belgium and France. Supply from Europe here tends to be specification-driven rather than price-driven, and the shipments are smaller and more frequent than the volumes further down the table.

What importers actually paid in duty

Duty treatment is split. 57.4% of the entered value was dutiable and the rest came in free, usually under a trade agreement or a duty-free provision in the tariff schedule. CBP collected $39.4 million in all, an effective 12% on the dutiable value and $6.89 per $100 of goods once the free entries are counted.

The spread between origins is real. Among origins with at least 2% of the heading, China paid the most duty relative to value — $22.28 per $100 — while Switzerland paid $0.23. On a $250,000 purchase order that gap is about $55,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 2930

34 ten-digit lines carried trade under this heading in the period. The largest, 2930.90.29.00, took 40% of the heading at $229 million. 2930.90.92.51, 2930.90.46.00 and 2930.40.00.00 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 $6.89 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: Switzerland (2930.90.29), China (2930.90.92) and Spain (2930.90.46). 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 2930 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.
