HFC blends covered by the scope are R-404A, a zeotropic mixture consisting of 52 percent 1,1,1 Trifluoroethane, 44 percent Pentafluoroethane, and 4 percent 1,1,1,2-Tetrafluoroethane; R-407A, a zeotropic mixture of 20 percent Difluoromethane, 40 percent Pentafluoroethane, and 40 percent 1,1,1,2-Tetrafluoroethane; R-407C, a zeotropic mixture of 23 percent Difluoromethane, 25 percent Pentafluoroethane, and 52 percent 1,1,1,2- Tetrafluoroethane; R-410A, a zeotropic mixture of 50 percent Difluoromethane and 50 percent Pentafluoroethane; and R-507A, an azeotropic mixture of 50 percent Pentafluoroethane and 50 percent 1,1,1-Trifluoroethane also known as R-507. The foregoing percentages are nominal percentages by weight. Actual percentages of single component refrigerants by weight may vary by plus or minus two percent points from the nominal percentage identified above.

HFC blends covered by the scope of the Order are currently classified in the Harmonized Tariff Schedule of the United States (HTSUS) at subheadings 3824.78.0020 and 3824.78.0050. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope is dispositive. See Order. Merchandise Subject to the Anti-Circumvention Inquiry This anti-circumvention inquiry covers imports of partially finished blends of HFC components R-32 (also known as Difluoromethane) and R-125 (also known as Pentafluoroethane) from China that must be further processed in the United States to create an HFC blend that would be subject to the Order. Applicable Statute Section 781 of the Act addresses circumvention of antidumping or countervailing duty orders. With respect to merchandise assembled or completed in the United States, section 781(a)(1) of the Act provides that if: (A) The merchandise sold in the United States is of the same class or kind as any other merchandise that is the subject of an AD order; (B) such merchandise sold in the United States is completed or assembled in the United States from parts or components produced in the foreign country with respect to which such order applies; (C) the process of assembly or completion in the United States is minor or insignificant; and (D) the value of the parts or components produced in the foreign country is a significant portion of the total value of the merchandise, then Commerce may include within the scope of the order the imported parts or components produced in the foreign country used in the completion or assembly of the merchandise in the United States, after taking into account any advice provided by the United States International Trade Commission (ITC) under section 781(e) of the Act. In determining whether the process of assembly or completion in the United States is minor or insignificant, section 781(a)(2) of the Act directs Commerce to consider: (A) the level of investment; (B) the level of research and development; (C) the nature of the production process; (D) the extent of production facilities; and (E) whether the value of processing performed in the United States represents a small proportion of the value of the merchandise sold in the United States. Section 781(a)(3) of the Act sets forth the factors to consider in determining whether to include parts or components in an AD order. Commerce shall take into account: (A) The pattern of trade, including sourcing patterns; (B) whether the manufacturer or exporter of the parts or components is affiliated with the person who assembles or completes the merchandise sold in the United States; and (C) whether imports into the United States of the parts or components produced in the foreign country have increased after the initiation of the investigation which resulted in the issuance of the order.

At a glance
The antidumping measure covers Hydrofluorocarbon Blends, imported from China. Case number A-570-028 is one of 540 active orders tracked in the database and was established 2020-01-27; the described product range determines which ten-digit lines inherit the cash-deposit obligation. Scope language in the Federal Register document controls.
As of dataset vintage 2026-10-16T16:09:24Z, yes: importers entering covered goods post a cash deposit at the current rate until Commerce's next administrative review publishes revised margins in the Federal Register. Deposit rates can change every review cycle, so confirm the latest Federal Register notice before you quote a figure to your customs broker.
These HTS headings are recorded in the case linkage: 3827.61.00, 3827.63.00, 3827.64.00, 3827.65.00, 3827.68.00, 3827.69.00. Confirm the exact ten-digit code against the published scope language, because product descriptions rather than codes alone define the legal boundary of the order, and scope rulings occasionally widen or narrow which lines inherit the deposit obligation.
