Products classified under HTS 2930.40.00.00
DL-Methionine
DL-Methionine is a synthetic racemic mixture of D- and L-methionine, a chemically defined organo-sulfur amino acid essential for animal nutrition. It falls under HTS 2930.40.00.00 as methionine, used primarily as a feed additive to supplement methionine-deficient diets in poultry and swine.
L-Methionine USP Grade
L-Methionine USP Grade is the natural levorotatory form of methionine, meeting United States Pharmacopeia standards for purity and use in medical and nutritional supplements. Classified under HTS 2930.40.00.00 as a separate chemically defined organo-sulfur compound.
Methionine Feed Grade 99%
Methionine Feed Grade 99% is a high-purity powder formulation of DL-methionine designed for livestock nutrition, containing minimal impurities as per chapter note (a). It is classified under HTS 2930.40.00.00 for methionine organo-sulfur compounds.
Hydroxy Analog of Methionine (MHA)
2-Hydroxy-4-(methylthio)butanoic acid, known as MHA, is a liquid methionine analog functioning as a rumen-stable sulfur source for ruminant feed. Though chemically distinct, it is often associated with methionine classification under HTS 2930.40.00.00 for organo-sulfur feed compounds.
L-Methionine with Stabilizer
L-Methionine powder with added anticaking stabilizer for preservation during transport, as permitted by chapter note (f). This chemically defined organo-sulfur compound remains classified under HTS 2930.40.00.00.
Methionine Calcium Salt
Calcium salt of DL-methionine, an organo-sulfur compound where the salt form follows the parent methionine per chapter note on inorganic salts (C)(1). Classified under HTS 2930.40.00.00.
Dry Methionine Powder 98.5%
Dry DL-Methionine powder at 98.5% purity with minor impurities, qualifying as chemically defined under chapter note (a). Used in pet food formulations, classified under HTS 2930.40.00.00.
