1. On 01/05/2026, Commerce published in the Federal Register its initiation of the countervailing duty investigation of chromium trioxide from India (91 FR 240). The effective date of this initiation is 12/29/2025 (the applicable date stated in the FR notice). 2. The merchandise subject to this investigation is chromium trioxide (Chemical Abstracts Services (CAS) registry number 1333-82-0), regardless of form (dry or solution). Chromium trioxide is an inorganic compound with the molecular formula CrO3 in dry form and H2CrO4 in solution form. All relevant formulas refer to same product with one unit of Chromium (as Cr+6) and three units of Oxygen, such as Cr4O12; and Cr0.25O0.75. The product in dry form is generally referred to as chromium trioxide, which is the acidic anhydride of chromic acid. Chromium trioxide in solution form may be referred to as chromic acid. However, the dry form may also be marketed under the name chromic acid. A non-exhaustive list of other names used for the subject merchandise includes: chromic anhydride, chromic trioxide, chromium (VI) oxide, monochromium trioxide, chromia, chromium (VI) trioxide, trioxochromium, and chromtrioxid. A non-exhaustive list of trade names for the subject merchandise includes: 11910080KROMSAV-ANHIDRID IP, Aktivkohle, impragniert, Typ PLWK, Chromsaure, and Chroomzuur. All chromium trioxide is covered by the scope of this investigation irrespective of purity, particle size, or physical form. Chromium trioxide is generally imported in dry form, including in the form of pellets, flakes, powders, or beads, but the scope includes chromium trioxide in solution form. Chromium trioxide that has been blended with another product or products other than water is included in the scope if the resulting mix contains 90 percent or more of chromium trioxide by total formula weight, such as chromium trioxide mixed with a catalyst to make the product ready for use in metal finishing applications. If chromium trioxide is imported blended with another product, only the chromium trioxide content of the blend is included within the scope. Subject merchandise also includes chromium trioxide that has been processed in a third country into a product that otherwise would be within the scope of this investigation, i.e., if any such further processing would not otherwise remove the merchandise from the scope of the investigation it is included in the scope of the investigation, including blending, flaking, mixing with water, or packaging. For example, the dry form of the subject merchandise may be imported into a third country and then processed into solution before shipment to the United States. Such a solution would be subject to the scope. The subject merchandise is provided for in subheading 2819.10.0000 of the Harmonized Tariff Schedule of the United States (HTSUS). In addition to 1333- 82-0, import documentation may also reflect CAS registry numbers 12324-05-9, 12324-08-2, and 1362947-20-3. Although the HTSUS subheading and CAS registry numbers are provided for convenience and customs purposes, the written description of the scope is dispositive. 3. This proceeding has been assigned case number C-533-945. 4.
