Products classified under HTS 2936.26.00.00
Cyanocobalamin USP Powder
Pharmaceutical-grade cyanocobalamin powder meeting USP standards, a synthetic form of Vitamin B12 used primarily as a vitamin supplement. Classified under HTS 2936.26.00.00 as it is a Vitamin B12 compound with direct B12 activity, unmixed and not in dosage form. This pure chemical form is essential for manufacturing tablets, injections, and fortified foods.
Mecobalamin Crystals
Mecobalamin (methylcobalamin), a coenzyme form of Vitamin B12 with full B12 activity, supplied as pure crystals for pharmaceutical use. Falls under HTS 2936.26.00.00 as a Vitamin B12 derivative used primarily as a vitamin, chemically defined and unmixed. Commonly used in nerve health supplements and injections.
Hydroxocobalamin Acetate
Hydroxocobalamin acetate, a Vitamin B12 derivative used in cyanide poisoning antidotes and B12 deficiency treatments, supplied as sterile powder. HTS 2936.26.00.00 classification applies to this unmixed B12 compound with vitamin activity. The acetate salt form maintains its primary vitamin function.
Cyanocobalamin 1% Feed Grade Premix
Cyanocobalamin premix standardized to 1% B12 activity on maltodextrin carrier for animal nutrition, where B12 remains the principal active. Classifies under HTS 2936.26.00.00 as Vitamin B12 derivative with diluent not rendering specific use (Chapter Note 2(d)). Used in livestock vitamin fortification.
Adenosylcobalamin (Cobamamide)
Adenosylcobalamin, the mitochondrial coenzyme form of Vitamin B12 (cobamamide), supplied as pure powder for supplement manufacturing. HTS 2936.26.00.00 covers this B12 derivative with full vitamin activity, chemically defined per Chapter Notes. Less stable form requiring specialized handling.
Vitamin B12 0.1% Mannitol Adsorbate
Cyanocobalamin adsorbed onto mannitol at 0.1% concentration for improved handling in tablet compression, maintaining B12 as principal active. Allowed under HTS 2936.26.00.00 per Chapter Note 2(e) as transport excipient not imparting specific use. Pharmaceutical intermediate form.
Methylcobalamin Sodium Salt
Mecobalamin sodium salt, water-soluble Vitamin B12 coenzyme derivative for oral and sublingual supplements. HTS 2936.26.00.00 applies to this organic salt of B12 base per Chapter Note 5(C)(1), retaining vitamin activity. High bioavailability form preferred in consumer products.
Cyanocobalamin Succinate Complex
Cyanocobalamin complexed with succinic acid for enhanced stability in liquid formulations, retaining full B12 vitamin activity. Classifies under HTS 2936.26.00.00 as B12 derivative; succinate qualifies as stabilizer (Chapter Note 2(f)). Used in energy drink fortifications.
Fermentation-Derived Cobamamide
Biosynthetic adenosylcobalamin (cobamamide) produced via microbial fermentation, identical to natural Vitamin B12 coenzyme. HTS 2936.26.00.00 covers both synthetic and natural-reproduced B12 compounds with vitamin activity, unmixed. Used in premium vegan supplements.
Vitamin B12 Reference Standard
Certified cyanocobalamin reference standard with assigned potency for analytical laboratories and pharmacopeia testing. HTS 2936.26.00.00 classification as pure B12 compound used primarily as vitamin calibration material. Supplied with NIST-traceable certificate.
