Potassium Sodium Tartrate (Rochelle Salt)
Potassium sodium tartrate, known as Rochelle salt, is a double salt of tartaric acid used in baking powders and as a sequestrant. Classified under HTS 2918.13.5000 as an 'other' salt of tartaric acid, it fits Chapter 29's scope for organic salts with alcohol function. Its chemical purity distinguishes it from mixtures.
Sodium Tartrate Dibasic
Sodium tartrate dibasic is a salt of tartaric acid employed in buffering solutions and as a food acidity regulator. It qualifies for HTS 2918.13.5000 as an 'other' ester or salt of tartaric acid with alcohol function but no other oxygen groups. Chapter 29 classification prioritizes the organic acid component.
Diethyl Tartrate
Diethyl tartrate is an ester of tartaric acid used as a chiral building block in organic synthesis and fragrances. It is classified under HTS 2918.13.5000 as an 'other' ester of tartaric acid per Chapter 29 note 3(A) for ester classification. The alcohol function without additional oxygen defines its placement.
Dimethyl Tartrate
Dimethyl tartrate serves as an intermediate in pharmaceutical synthesis and polymer production. Under HTS 2918.13.5000 as 'other' tartaric acid esters, it adheres to Chapter 29 rules for carboxylic acids with alcohol function. Its simple ester structure avoids reclassification.
Ammonium Bitartrate
Ammonium bitartrate is used in wine stabilization and as a lab reagent. Classified in HTS 2918.13.5000 as an 'other' salt of tartaric acid, per Chapter 29 note 1(C)(1) for organic salts. The bitartrate form retains carboxylic alcohol function classification.
