Hydraulic-cylinder AD/CVD injury investigations open across five countries

The U.S. International Trade Commission instituted preliminary antidumping and countervailing-duty injury investigations covering linear hydraulic cylinders from Canada, China, India, Mexico, and South Korea. The investigations were instituted on July 29, 2026 in response to a petition filed that day and published in the Federal Register on August 4.

The antidumping investigations cover imports from all five named countries. The countervailing-duty investigations concern alleged subsidies by China, India, and Mexico; the notice does not identify countervailing-duty investigations for Canada or South Korea.

The notice lists HTSUS subheadings 8412.21.00 and 8412.90.90 for the merchandise under investigation. Those headings are useful screening flags, but the institution notice does not publish a complete written product scope. Importers should not infer that every item in either heading is covered or that items outside those headings are necessarily excluded.

This is the preliminary injury phase. It does not impose an antidumping or countervailing-duty order, announce a dumping or subsidy rate, or direct CBP to begin collecting new cash deposits. The USITC says it must reach its preliminary determination by September 14 unless Commerce extends the initiation timetable, and transmit its views to Commerce by September 21.

Parties must file entries of appearance and applications for access to business proprietary information no later than seven days after the August 4 publication. Requests to appear at the August 19 staff conference are due by noon on August 17. Written testimony and conference material are due by 4 p.m. on August 18, and written briefs are due by 5:15 p.m. on August 24.

Action items

• Screen current and planned imports from Canada, China, India, Mexico, and South Korea under HTSUS 8412.21.00 and 8412.90.90, then confirm product coverage against the complete written scope when Commerce publishes it.
• Preserve purchase orders, specifications, supplier identities, country-of-origin support, and entry data for potentially affected cylinders and parts.
• Keep current duty treatment unchanged unless and until Commerce and CBP issue operative instructions.
• Coordinate participation and filing deadlines with qualified trade counsel if the investigation materially affects the business.
