2930.40.00.00 - Methionine

This HTS code, 2930.40.00.00, specifically classifies Methionine. Methionine is an essential amino acid, vital for protein synthesis and metabolic functions in both humans and animals. Its primary use is as a nutritional supplement in animal feed to ensure adequate protein intake and growth, particularly in poultry and swine. It is also utilized in pharmaceuticals and food fortification.

Within the broader category of organo-sulfur compounds, Methionine stands apart from its siblings. For instance, codes such as 2930.10.01.00 and 2930.60.00.00 cover specific amino thiols with different structural characteristics and industrial applications, often as intermediates or reagents. Similarly, 2930.20 pertains to thiocarbamates and dithiocarbamates, which are distinct classes of sulfur-containing organic compounds with applications in pesticides and rubber processing. The thiuram disulfides (2930.30) and bis(2-hydroxyethyl)sulfide (2930.70.00.00) also represent separate chemical structures with their own unique uses, such as accelerators in rubber vulcanization or chemical intermediates.

As a leaf node within the HTS, 2930.40.00.00 does not have further subcategories. Therefore, the classification rests solely on the identification of the product as Methionine. This means that any product imported or exported that is definitively Methionine, regardless of its specific grade or purity, will fall under this specific heading, provided it meets the general requirements for classification within Chapter 29 of the Harmonized Tariff Schedule.
