N354139 October 22, 2025 OT:RR:NC:N3:138 CATEGORY: Origin Prakash Rajendran Viona Pharmaceuticals, Inc. 20 Commerce Drive, Suite 340 Cranford, NJ 07016 RE: The country of origin of Metronidazole Tablets, USP in dosage form Dear Mr. Rajendran: In your letter dated September 23, 2025, you requested a country of origin ruling on Metronidazole Tablets. Metronidazole, imported in 250 mg and 500 mg tablets, is a medicinal preparation containing Metronidazole, a synthetic nitroimidazole antimicrobial agent, as the active ingredient. It is indicated for the prevention and treatment of certain bacterial and protozoal infections. You stated that the active pharmaceutical ingredient (API), Metronidazole, is manufactured in India and that the finished tablets in dosage form are also made in India. In India, Metronidazole will be mixed with various inactive ingredients to produce the final Metronidazole Tablets in dosage form. When determining the country of origin, the substantial transformation analysis is applicable. See, e.g., Headquarters Ruling Letter (“HQ”) H301619, dated November 6, 2018. The test for determining whether a substantial transformation will occur is whether an article emerges from a process with a new name, character, or use different from that possessed by the article prior to processing. See Texas Instruments Inc. v. United States, 681 F.2d 778 (C.C.P.A. 1982). This determination is based on the totality of the evidence. See National Hand Tool Corp. v. United States, 16 C.I.T. 308 (1992), aff’d, 989 F.2d 1201 (Fed. Cir. 1993). In this case, the active ingredient Metronidazole is made in India and the mixing of the API with the inactive ingredients into the final tablets is also made in India. Therefore, we find the country of origin of the Metronidazole Tablets in dosage form will be India, where the API is made. This merchandise may be subject to the Federal Food, Drug, and Cosmetic Act and/or The Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (The Bioterrorism Act), which are administered by the U.S. Food and Drug Administration (FDA).

The holding set forth above applies only to the specific factual situation and merchandise description as identified in the ruling request. This position is clearly set forth in Title 19, Code of Federal Regulations (CFR), Section 177.9(b)(1). This section states that a ruling letter is issued on the assumption that all of the information furnished in the ruling letter, whether directly, by reference, or by implication, is accurate and complete in every material respect. In the event that the facts are modified in any way, or if the goods do not conform to these facts at time of importation, you should bring this to the attention of U.S. Customs and Border Protection (CBP) and submit a request for a new ruling in accordance with 19 CFR 177.2.
