HS Code for Methionine

Methionine is classified under HS code 2930.40. This classification is based on its molecular structure as an organo-sulphur compound. While methionine is an amino acid, the Harmonized System dictates that organo-sulphur compounds are classified under heading 2930, which takes precedence over other headings in Chapter 29 that might otherwise apply to amino acids (such as 2922). Methionine contains a thioether group, making the presence of the sulfur atom the defining characteristic for its HS placement. This code covers both the DL-methionine (the synthetic form commonly used in animal feed) and the L-methionine (the naturally occurring isomer). Because methionine is a critical nutrient in the poultry and livestock industries, having a dedicated subheading (2930.40) allows for precise tracking of its global trade and ensures consistent application of customs duties for this essential amino acid.

Common Misclassification

A frequent misclassification occurs with HS code 2922.49, which covers "other" amino acids. Many users assume all amino acids belong in heading 2922; however, the presence of sulfur atoms moves methionine to 2930.40. Another common error is 2309.90, which covers preparations of a kind used in animal feeding. If methionine is pure, it must be in 2930.40. It only moves to 2309.90 if it has been mixed with other ingredients or carriers to form a prepared feed supplement.

FAQ

What is the HS code for Methionine?

The HS code for methionine is 2930.40, classified under organo-sulphur compounds.

Is methionine hydroxy analogue (MHA) under the same code?

No, methionine hydroxy analogue is typically classified under HS code 2930.90 because it lacks the amino group required to be considered the exact chemical methionine defined in 2930.40.
