Last updated: August 2026 dataPneumatic linear actuators use compressed air to generate straight-line force and are ubiquitous in factory automation, packaging machinery, and process control systems. The US schedule divides this heading between tie-rod pneumatic cylinders (8412310040) and all other linear-acting pneumatic motors excluding tie-rod construction (8412310080) — a narrower split than the hydraulic cylinder heading, reflecting the more standardized design landscape in pneumatics. Mexico leads US imports, followed by Germany and Japan, with China also a notable source. Importers sourcing from China should be aware that pneumatic components may be subject to Section 301 tariffs depending on the specific product and applicable exclusions.

Pneumatic linear actuators classified under 841231 lines sourced from China may be subject to Section 301 tariffs. The applicability depends on the specific 10-digit HTS line and whether any product-specific exclusions have been granted or reinstated by USTR. Importers should check the current USTR exclusion list and CBP's Section 301 guidance at the time of entry, as exclusion status changes periodically.
Tie-rod pneumatic cylinders (8412310040) use external threaded rods running the length of the cylinder to clamp the end caps, a construction common in standard industrial automation. Non-tie-rod cylinders (8412310080) include welded, profile-barrel, and compact designs. The construction method is the controlling factor, and importers should confirm the cylinder body type from manufacturer specifications or product drawings to select the correct line.
