Products classified under HTS 2937.12.00.00
Human Insulin (rDNA)
Recombinant human insulin produced via DNA technology, a polypeptide hormone used primarily for treating diabetes mellitus. Classified under HTS 2937.12.00.00 as a synthetic reproduction of insulin, the exact structural analogue of natural human insulin. Meets chapter 29 requirements for chemically defined organic compounds used as hormones.
Insulin Lispro (Humalog)
Rapid-acting insulin analogue created by recombinant DNA technology with amino acid modifications for faster absorption. Falls under HTS 2937.12.00.00 as a structural analogue of insulin used primarily as a hormone for glycemic control. Qualifies as a chain-modified polypeptide hormone per chapter notes.
Insulin Glargine (Lantus)
Long-acting basal insulin analogue produced by recombinant DNA, modified for prolonged release profile. HTS 2937.12.00.00 covers this as a derivative and structural analogue of insulin used primarily as a hormone. Chemically defined polypeptide meeting Chapter 29 hormone classification criteria.
Insulin Aspart (NovoRapid)
Fast-acting insulin analogue with aspartic acid substitution, rDNA origin, used for mealtime glycemic control. Classified in 2937.12.00.00 as insulin structural analogue per heading description for chain-modified polypeptides used as hormones.
Insulin Detemir (Levemir)
Soluble long-acting insulin analogue with fatty acid modification for albumin binding. HTS 2937.12.00.00 applies to this rDNA-produced derivative used primarily as a basal insulin hormone replacement.
Insulin Sodium Salt USP
Pharmaceutical grade sodium salt of bovine or porcine insulin meeting USP standards. Explicitly covered by HTS 2937.12.00.00 as 'insulin and its salts' for therapeutic hormone use.
Recombinant Insulin API Powder
Bulk active pharmaceutical ingredient powder of human insulin produced by recombinant E. coli or yeast. HTS 2937.12.00.00 for pure synthetic insulin substance before formulation into dosage forms.
Porcine Insulin Zinc Suspension
Zinc suspension of porcine-derived insulin for extended action profile. While containing zinc, classifies under 2937.12.00.00 as insulin salt/derivative, not organo-inorganic compound of 2931.
Insulin Glulisine (Apidra)
Ultra-rapid acting insulin analogue with glycine/lysine modifications at B-chain. HTS 2937.12.00.00 covers rDNA-produced structural analogues used primarily as polypeptide hormones.
Bovine Insulin Crystals
Highly purified crystalline form of bovine pancreas-derived insulin. Classifies under HTS 2937.12.00.00 as natural insulin hormone meeting chapter purity requirements.
Insulin Degludec API
Ultra-long acting insulin analogue with side chain modification for multi-hexamer formation. rDNA product classified in 2937.12.00.00 as polypeptide hormone structural analogue.
Neutral Protamine Hagedorn (NPH) Insulin
Isophane insulin suspension complexed with protamine for intermediate action. Despite protamine addition, classifies as insulin derivative under HTS 2937.12.00.00 per hormone heading specificity.
Regular Human Insulin 100 IU/mL Solution
Sterile aqueous solution of recombinant human insulin U-100 strength. As pure dissolved hormone, falls under HTS 2937.12.00.00 per chapter note (d) for water-dissolved compounds.
Mixed Insulin 70/30 (70% NPH/30% Regular)
Biphasic mixture of intermediate and short-acting insulin components. Classifies under 2937.12.00.00 as insulin derivatives despite mixture, per chapter note on classification by last occurring heading.
Insulin Zinc Crystals (Lente Insulin)
Amorphous and crystalline zinc-insulin complex providing intermediate duration. HTS 2937.12.00.00 as insulin derivative; zinc modification doesn't trigger Chapter 29 organo-inorganic heading per notes.
