Subheadings
Products classified under Tariff item 2937.12
Bovine Insulin Crystals
Bovine insulin crystals are a highly purified, crystalline form of insulin derived from bovine pancreas. As a natural polypeptide hormone, it falls under tariff item 2937.12.00, which covers insulin and its salts, including natural or synthetic reproductions.
2937.12.00Human Insulin (rDNA)
Recombinant human insulin produced via DNA technology is a synthetic reproduction of the natural hormone, structurally identical to human insulin. It is classified under tariff item 2937.12.00 as insulin, regardless of its method of production.
2937.12.00Insulin Aspart (NovoRapid)
Insulin aspart is a rapid-acting insulin analogue produced by recombinant DNA technology, with a single amino acid substitution compared to human insulin. As a structural analogue of insulin used primarily for its hormonal effect, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Degludec API
Insulin degludec is an ultra-long-acting insulin analogue with a side-chain modification that promotes multi-hexamer formation. As a chain-modified polypeptide hormone used primarily as insulin, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Detemir (Levemir)
Insulin detemir is a soluble long-acting insulin analogue with a fatty acid modification that enables albumin binding. As a derivative of insulin used primarily as a basal hormone replacement, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Glargine (Lantus)
Insulin glargine is a long-acting basal insulin analogue produced by recombinant DNA technology, modified for a prolonged release profile. As a derivative and structural analogue of insulin used primarily as a hormone, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Glulisine (Apidra)
Insulin glulisine is an ultra-rapid-acting insulin analogue with glycine and lysine modifications at the B-chain. As a recombinant DNA-produced structural analogue used primarily as a polypeptide hormone, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Lispro (Humalog)
Insulin lispro is a rapid-acting insulin analogue created by recombinant DNA technology with amino acid modifications for faster absorption. As a structural analogue of insulin used primarily as a hormone, it is classified under tariff item 2937.12.00.
2937.12.00Insulin Sodium Salt USP
Insulin sodium salt is a pharmaceutical-grade sodium salt of bovine or porcine insulin meeting USP standards. As a salt of insulin, it is explicitly covered by tariff item 2937.12.00, which includes insulin and its salts.
2937.12.00Insulin Zinc Crystals (Lente Insulin)
Insulin zinc crystals are amorphous and crystalline zinc-insulin complexes providing intermediate duration of action. As an insulin derivative, the zinc modification does not trigger classification as an organo-inorganic compound, so it falls under tariff item 2937.12.00.
2937.12.00Mixed Insulin 70/30 (70% NPH/30% Regular)
Mixed insulin 70/30 is a biphasic mixture of intermediate and short-acting insulin components. As a mixture of insulin derivatives, it is classified under tariff item 2937.12.00, with classification determined by the last heading in numerical order per Chapter 29 Note 3.
2937.12.00Neutral Protamine Hagedorn (NPH) Insulin
Neutral Protamine Hagedorn (NPH) insulin is an isophane insulin suspension complexed with protamine for intermediate action. Despite the protamine addition, it is classified as an insulin derivative under tariff item 2937.12.00 due to the hormone heading's specificity.
2937.12.00Porcine Insulin Zinc Suspension
Porcine insulin zinc suspension is a zinc suspension of porcine-derived insulin for extended action. While it contains zinc, it is classified under tariff item 2937.12.00 as an insulin salt or derivative, not as an organo-inorganic compound of heading 29.31.
2937.12.00Recombinant Insulin API Powder
Recombinant insulin API powder is a bulk active pharmaceutical ingredient of human insulin produced by recombinant E. coli or yeast. As a pure synthetic insulin substance before formulation, it is classified under tariff item 2937.12.00.
2937.12.00Regular Human Insulin 100 IU/mL Solution
Regular human insulin 100 IU/mL solution is a sterile aqueous solution of recombinant human insulin at U-100 strength. As a pure hormone dissolved in water, it falls under tariff item 2937.12.00 per Chapter 29 Note 1(d) for water-dissolved compounds.
