N354129 October 21, 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 Diltiazem Hydrochloride Tablets USP in dosage form Dear Mr. Rajendran: In your letter dated September 23, 2025, you requested a country of origin ruling on Diltiazem Hydrochloride Tablets. Diltiazem Hydrochloride, imported in 30 mg, 60 mg, 90 mg and 120 mg tablets, is a calcium ion cellular influx inhibitor. It is indicated for the management of chronic stable angina and angina due to coronary artery spasm. You stated the active pharmaceutical ingredient (API), Diltiazem Hydrochloride, is manufactured in India and that the finished tablets in dosage form are also made in India. In India, the Diltiazem Hydrochloride will be mixed with various inactive ingredients to produce the final Diltiazem Hydrochloride 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 Diltiazem Hydrochloride is made in India and the mixing of the API with the inactive ingredients into the final tablets in dosage form is also made in India. Therefore, we find the country of origin of the Diltiazem Hydrochloride Tablets in dosage form will be India, where the API is made.
