On July 29, 2026, the Hydraulic Cylinders Fair Trade Coalition and its individual members, Aggressive Hydraulics, Inc., Hol-Mac Corporation, Ligon Hydraulics, Prince Manufacturing Corporation, PTC Alliance LLC, Rosenboom Machine & Tool, Inc., Scot Industries, Inc., Stillwell Inc., and Texas Hydraulics, Inc. (Petitioners) filed petitions requesting the imposition of antidumping duties on imports of certain linear hydraulic cylinders and parts thereof (Hydraulic Cylinders) from Canada, China, India, Mexico, and South Korea, and countervailing duties on imports from China, India, and Mexico.
SCOPE OF THE INVESTIGATION
The proposed scope of these investigations is as follows:
The scope of these investigations covers certain linear acting hydraulic cylinders (also known as hydraulic power engines) and certain barrel and piston rod components and assemblies of linear acting hydraulic cylinders. Covered linear acting hydraulic cylinders have barrels made of steel, a bore size (inner diameter) of 25.4 mm (one inch) or more, and a return (retracted) length of 102.1 mm (four inches) or more. For purposes of this scope, the return (retracted) length is the overall end-to-end measurement of the hydraulic cylinder unit when in the retracted position. The scope covers all such linear acting hydraulic cylinders meeting the physical description above, including but not limited to the following linear hydraulic cylinder designs: tie-rod, welded body, telescopic, plunger, rodless, differential, position sensing, single acting, double acting, displacement, ram type, piggy-back, double rod, rod-fed, and spring return linear acting hydraulic cylinders. All covered cylinders are hydraulically activated. The incorporation of a spring into the design of a hydraulic cylinder otherwise meeting the description above does not exclude a product from the scope.
The scope also covers (1) steel barrel components, (2) steel piston rod components, and (3) any component of a linear hydraulic cylinder that is attached to, assembled with or shipped with a covered steel barrel or a covered piston rod.
Covered barrel components include processed welded or seamless steel tubes four inches or more in length with an inner diameter of one inch (25.4 mm) or more, that have had their inner diameter precision machined (such as through honing or skiving and burnishing), and have otherwise been processed to the point of having as their sole or predominant use a barrel for an in-scope hydraulic cylinder. Such processing may include but is not limited to cutting-to-length, end-finishing (e.g., machine-threading, chamfering, etc.), port drilling, and the addition of weldments, or any combination thereof.
Covered piston rods are solid or hollow bars or tubes that have been hard chrome plated or chrome coated, cut to length, and machined to be a piston rod.
Included in the scope are any attachments, parts, or components that are imported with, attached to, or invoiced with a linear hydraulic cylinder or covered component, including but not limited to cylinder mounting parts (e.g., flanges, trunnions, clevises, lugs, etc.), connectors attached to pistons or piston rods, pistons, or hydraulic tubing or hydraulic lines (regardless of material) such as for connections to a hydraulic pump.
Also included in the scope are any hydraulic cylinders meeting the physical description above attached to or imported with any equipment or parts of equipment classified in Chapter 84 of the Harmonized Tariff Schedule of the United States. When a hydraulic cylinder is attached to or imported with any equipment or parts of equipment classified in Chapter 84 of the Harmonized Tariff Schedule of the United States, only the hydraulic cylinder is covered by the scope.
Subject merchandise also includes hydraulic cylinders, components, and subcomponents that undergo assembly or further working in a third country in any manner that would not otherwise remove the merchandise from the scope of the investigations if performed in the country of manufacture of the in-scope hydraulic cylinder. Subject merchandise also includes hydraulic cylinders, components, and subassemblies that are attached to any equipment or parts of equipment classified in Chapter 84, as discussed in the immediately preceding paragraph, if such attachment occurs in a third country.
Excluded from the scope are pneumatic power engines and motors.
Also excluded from the scope are hydraulic cylinders and parts that are covered by preexisting antidumping (“AD”) and countervailing duty (“CVD”) orders. However, to the extent such AD or CVD orders are revoked, the hydraulic cylinders would be subject merchandise.
All products that meet the written physical description are within the scope of the investigations unless specifically excluded or covered by the scope of an existing order.
The products subject to these investigations are currently classified in the Harmonized Tariff Schedule of the United States (HTSUS) under statistic reporting numbers 8412.21.0015, 8412.21.0030, 8412.21.0045, 8412.21.0060, 8412.21.0075, and 8412.90.9005. The HTSUS subheadings above are provided for convenience and Customs purposes only. The written description of the scope of these investigations is dispositive.
