RE: The tariff classification and country of origin of Calcitonin Salmon Injection, USP in dosage form
Dear Mr. Shah:
In your letter dated December 22, 2025, you requested a tariff classification and country of origin
determination ruling.
Calcitonin Salmon Injection, imported in 400 USP Units/2 mL vials, is a synthetic polypeptide hormone that
acts as a calcitonin receptor agonist. It is indicated for the treatment of Paget’s disease, hypercalcemia, and
postmenopausal osteoporosis.
The applicable subheading for the Salmon Calcitonin Injection, USP in dosage form will be 3004.39.0050,
Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Medicaments … consisting
of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses … or in forms
or packings for retail sale: Other, containing hormones or other products of heading 2937: Other: Other.”
The general rate of duty will be free.
You also requested a country of origin determination. You stated that the active pharmaceutical ingredient
(API), Calcitonin Salmon is manufactured in Spain and that the finished Calcitonin Salmon Injection in
dosage form is made in India. In India, the Calcitonin Salmon will be mixed with various inactive ingredients
to produce the final Calcitonin Salmon Injection 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, we find the mixing of the active ingredient Calcitonin Salmon (made in Spain) with the inactive
ingredients into the final dosage Calcitonin Salmon Injection, USP in India does not result in a substantial
transformation and the country of origin will be Spain.
