1. On 05/27/2026, Commerce published in the Federal Register its initiation of the countervailing duty investigation of stationary and portable air compressors from the People's Republic of China (91 FR 31425). 2. The merchandise covered by this investigation consists of certain stationary and portable air compressors, whether electric, gas, or battery powered, including electric motor and gasoline engine powered air compressors with either oil free or oil lubricated reciprocating pumps, and with an integrated pressure vessel that ranges in size from 1 to 80 gallons. The compressors may be either direct drive or belt driven. Direct drive air compressors included in the scope have a motor connected directly to the compressor element. Belt driven air compressors included in the scope have a motor connected to the compressor crankshaft with a belt. Direct drive air compressors are more often portable but can be stationary, while belt driven air compressors are either portable or stationary. Covered air compressors have a power level designation between 373 watts (0.5 HP) and 22.37 kilowatts (30 HP). Specifically, portable air compressors often range in power from 0.5HP (373 watts) to 15HP (11.19KW). Reciprocating stationary air compressors range in power from 0.5HP (373 watts) to 25HP (18.64KW). However, a portable or stationary air compressor with a different power level, within the range of 373 watts to 22.37 KW, and otherwise meeting the language of the scope, is covered by the scope. The scope includes only certain reciprocating (piston) compressors, which use a piston moving back and forth in a cylinder to compress the air. The scope also includes unfinished compressors exported from the subject countries. Subject merchandise also includes finished and unfinished compressors that are further processed in a third country or in the United States, including, but not limited to, assembly or any other processing that would not otherwise remove the merchandise from the scope of this investigation if performed in the country of manufacture of the in-scope air compressors. The additional parts used to complete "unfinished compressors" in a third country are subject to the scope of this investigation. For the purposes of this scope, "unfinished compressors" are compressors which require additional fabrication such as labeling, and packaging, and kitting operations adding accessories. Specifically included in the scope are compressors which are imported as part of a package with accessories or other products, or kit. Such accessories include but are not limited to hoses, fittings, tool kits, oils, nail guns, pneumatic paint sprayers, air ratchet wrenches, air grease guns, air drills, air hammers, air sanders, air inflators, and air impact drivers. If such accessories or other products are imported separately from the air compressor, such products are not subject to the scope of this investigation. Specifically excluded from the scope are AC, DC, and battery powered inflators without an integrated air tank or air reservoir that have an output of 1 CFM or less. The scope excludes rotary compressors. Types of rotary compressors excluded from the scope are rotary screw, rotary vane, and scroll compressors. The scope also excludes dynamic compressors. Types of dynamic compressors excluded from the scope are centrifugal compressors and axial compressors where rotating impellers or blades compress air. The in-scope stationary air compressors are classified under subheadings 8414.80.1615, 8414.80.1625, and 8414.80.1635 of the Harmonized Tariff Schedule of the United States (HTSUS). The in-scope portable air compressors are classified under subheading 8414.80.1685 of the HTSUS. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the covered merchandise is dispositive. 3. This proceeding has been assigned case number C-570-233. 4. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIV: JHE.) 5. There are no restrictions on the release of this information. Alexander Amdur
