Producer Gas, Water Gas, and Acetylene Gas Generators

$3.1MU.S. imports · April 2026SITC 74171

U.S. imports of producer gas, water gas, and acetylene gas generators (SITC 74171) totaled $3.1M in April 2026, traded with 20 countries.

Importers of Producer Gas, Water Gas, and Acetylene Gas Generators paid $95K in duties in April 2026 — an effective duty rate of 3.4% on $2.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Producer Gas, Water Gas, and Acetylene Gas Generators imports of $3.1M in April 2026 ran 69% above the year-to-date monthly average of $1.8M.

Last updated: April 2026 data

Producer gas generators, water gas generators, acetylene gas generators, and similar water-process gas generators are industrial capital equipment used in chemical synthesis, metal cutting and welding supply, and energy production from solid fuels. Acetylene generators in particular serve the industrial gases sector, where on-site generation from calcium carbide is an alternative to cylinder supply. Classification requires careful attention to the generation process — units operating on water-process chemistry classify here, while other gas-generation technologies may fall under different SITC headings.

Frequently Asked Questions

What distinguishes a 'water process' gas generator from other gas-generation equipment for classification purposes?

Water process gas generators produce combustible gases through chemical reactions involving water or steam — such as the reaction of steam with coke to produce water gas, or the reaction of calcium carbide with water to produce acetylene. Gas generators that operate on different principles (such as electrolysis or compression of natural gas) do not fall under this heading and classify elsewhere in the SITC schedule.

Are acetylene generators subject to any special safety or regulatory requirements at US import?

Acetylene generators are pressure-generating equipment and may be subject to OSHA safety standards and, depending on design, ASME pressure vessel codes for domestic installation. Importers should verify that equipment meets applicable US safety standards before entry and consult with the relevant regulatory authority, as non-compliant pressure equipment may be refused admission or require modification.
