Products classified under HTS 2918.16.50
Calcium Gluconate USP Powder
Calcium gluconate is the calcium salt of gluconic acid, a carboxylic acid with alcohol function, classified under HTS 2918.16.50 as 'other' gluconic acid salts. Its chemical structure features the gluconate anion derived from oxidation of glucose, retaining multiple hydroxyl groups without other oxygen functions.
Ferrous Gluconate FCC Granules
Ferrous gluconate, the iron(II) salt of gluconic acid, provides bioavailable iron for nutritional applications and falls under HTS 2918.16.50 as an 'other' gluconic acid salt. The compound retains the characteristic polyhydroxy carboxylic acid structure without additional oxygen functions.
Gluconic Acid 50% Aqueous Solution
Gluconic acid solution at 50% concentration is the pure acid form with alcohol functions, permitted under Chapter 29 note (d) for water-dissolved products. Classified in HTS 2918.16.50 as 'other' gluconic acid, its structure features five hydroxyl groups on the carbohydrate-derived chain.
Potassium Gluconate Crystals USP
Potassium gluconate provides potassium supplementation from gluconic acid salt, classified under HTS 2918.16.50 per Chapter 29 salt classification rules. The crystalline form maintains purity as a simple organic salt without additional functional groups.
Magnesium Gluconate Hydrate Powder
Magnesium gluconate dihydrate, Mg(C6H11O7)2·2H2O, exemplifies gluconic acid metal salt under HTS 2918.16.50. The hydrate form retains classification as the organic acid salt per Chapter 29 note on coordination compounds.
Zinc Gluconate Lozenges Base (Bulk)
Bulk zinc gluconate powder serves as active ingredient base for cold remedy lozenges, classified as HTS 2918.16.50 organic metal salt. Excludes finished dosage forms covered by Chapter 30.
Glucono-Delta-Lactone (GdL) Powder
Glucono-delta-lactone, the cyclic ester of gluconic acid, technically qualifies under broader carboxylic acid with alcohol function but commercially follows HTS 2918.16.50 pattern. Used as slow-release acidulant in food processing.
Sodium Gluconate Technical Grade
Technical grade sodium gluconate serves as concrete admixture and industrial chelator, classified HTS 2918.16.50 as gluconic acid salt. Lower purity than USP but retains organic salt classification.
