U.S. imports of Air & Gas Compressors (NAICS 333912) totaled $828.4M in August 2026, imported from 111 countries.
Importers of Air & Gas Compressors paid $101.2M in duties in August 2026, an average duty rate of 12.37% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Air & Gas Compressors imports of $828.4M in August 2026 ran 19% above the year-to-date monthly average of $695.5M.
Last updated: August 2026 dataReciprocating, rotary-screw, and centrifugal compressors for air and industrial gases serve as critical infrastructure inputs across oil and gas, manufacturing, and HVAC sectors. Trade classification turns on compression mechanism, pressure rating, and whether the unit is hermetic or open-type — distinctions that determine the applicable HTS heading and any Section 301 exposure for China-origin equipment. Importers should verify whether compressor assemblies are classified as complete machines or as parts, since the two paths carry different duty treatment.

CBP generally applies the 'essential character' and 'complete or finished article' rules: a unit shipped with its motor, drive, and control panel is typically classified as a complete compressor, while bare pump heads or cylinders are classified as parts. Importers should obtain a binding ruling when the line is unclear, as the duty difference can be significant.
Many compressor categories sourced from China are subject to Section 301 tariffs. The specific list and rate depend on the 10-digit HTS classification of the individual unit, so importers should confirm the applicable subheading and check the current Section 301 annexes before entry.
