Products classified under HTS 2923.10.00.00
Choline Chloride
Choline chloride is a quaternary ammonium salt commonly used as a nutritional supplement in animal feed to prevent fatty liver disease and support growth. It falls under HTS 2923.10.00.00 as a chemically defined salt of choline, fitting the chapter's scope for separate organic compounds and their salts.
Choline Bitartrate
Choline bitartrate is the tartaric acid salt of choline, widely used in dietary supplements for human consumption to support liver health and cognitive function. Classified under HTS 2923.10.00.00 as a choline salt per chapter notes on organic salts.
Choline Hydroxide
Choline hydroxide, also known as choline base in solution, serves as a strong organic base in chemical synthesis and cosmetics formulation. It qualifies under HTS 2923.10.00.00 as a quaternary ammonium hydroxide explicitly covered in the heading.
Choline DiHydrogen Citrate
This citrate salt of choline is used in pharmaceuticals and nutritional products for its bioavailability in treating choline deficiencies. Falls under HTS 2923.10.00.00 following chapter note (C) classifying salts with the organic base component.
Choline Acetylsalicylate
A soluble salt form of aspirin (acetylsalicylic acid) with choline, used in effervescent analgesic tablets for faster absorption. HTS 2923.10.00.00 applies as the choline salt per note (C)(2), classifying with the base occurring later in chapter order.
Choline Theophyllinate
Salt of choline and theophylline used as a bronchodilator in respiratory medications with improved solubility. Classified under HTS 2923.10.00.00 as choline's salt, taking precedence over the acid component per chapter salt classification rules.
Choline Iodide
Choline iodide provides both choline nutrition and iodine supplementation in animal feeds and aquaculture diets. HTS 2923.10.00.00 covers this as a chemically defined choline salt, even with iodine counterion.
Choline Gluconate
Water-soluble choline gluconate salt used in liquid nutritional supplements and parenteral nutrition solutions. Falls under HTS 2923.10.00.00 as a quaternary ammonium salt solution per chapter note (d).
Choline Orotate
Choline orotate combines choline with orotic acid for liver protection supplements targeting methylation pathways. Classified HTS 2923.10.00.00 following numerical order rule for mixed-function organic salts.
Choline Ascorbate (Vitamin C Choline Salt)
Antioxidant salt combining choline and ascorbic acid, used in stabilized vitamin C formulations for cosmetics and supplements. HTS 2923.10.00.00 per salt classification with quaternary ammonium base.
