Overview

This HTS classification, 9606.21.20.00, specifically covers buttons that are made from casein. Casein is a protein derived from milk and is a type of plastic. Therefore, this category is for buttons manufactured using casein as the primary material.

This category is distinct from its sibling categories by its explicit material specification. While 9606.21.40.00 deals with buttons made of acrylic or polyester resins, and 9606.21.60.00 covers other types of plastic buttons not elsewhere specified, 9606.21.20.00 is exclusively for those manufactured from casein. The defining characteristic here is the origin of the plastic material.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under this heading is complete once it is determined that the button is of plastic and specifically manufactured from casein. Examples of such buttons would include those with a milk-derived plastic composition, often used for apparel or other textile articles.
