Diethyl L-Tartrate
Diethyl L-tartrate is the ethyl ester of L-tartaric acid. Under Chapter 29 Note 5(B), esters of ethyl alcohol with acid-function organic compounds are classified in the same heading as the corresponding acid, so this product falls under tariff item 2918.12.00 as tartaric acid. It is used as a chiral auxiliary in organic synthesis.
DL-Tartaric Acid (Racemic)
DL-Tartaric acid is the racemic mixture of D- and L-tartaric acid, a chemically defined organic compound with two hydroxyl groups and two carboxyl groups. Under Chapter 29 Note 1(b), mixtures of isomers of the same organic compound are covered, so it classifies under tariff item 2918.12.00. It is used in pharmaceuticals and as a chiral resolving agent.
D(-)-Tartaric Acid
D(-)-Tartaric acid is the D-enantiomer of tartaric acid, a chemically defined organic compound with the same molecular structure as L-tartaric acid but opposite optical rotation. Under Chapter 29 Note 1(a), separate chemically defined organic compounds are covered, so it classifies under tariff item 2918.12.00. It is used in the resolution of racemic mixtures and specialty synthesis.
L(+)-Tartaric Acid
L(+)-Tartaric acid is the naturally occurring enantiomer of tartaric acid, a dicarboxylic acid with two hydroxyl groups. Under Chapter 29 Note 1(a), it is a separate chemically defined organic compound, classifying under tariff item 2918.12.00. It is used in food, pharmaceuticals, and as a chiral building block.
Monohydrate Tartaric Acid Crystals
Tartaric acid monohydrate is a crystalline form of tartaric acid with one water molecule per molecule of tartaric acid. Under Chapter 29 Note 1(d), products dissolved in water are covered, so this hydrate classifies under tariff item 2918.12.00. It is used in effervescent formulations and as a buffer.
Natural Tartaric Acid from Wine Lees
Natural tartaric acid extracted from wine lees is chemically identical to synthetic tartaric acid, with the same molecular structure. Under Chapter 29 Note 1(a), the origin does not affect classification, so it falls under tariff item 2918.12.00. It is preferred for organic certification and natural product applications.
