0402.99.10.00 - In airtight containers

This HTS category, 0402.99.10.00, specifically covers milk and cream that has been concentrated or contains added sugar or other sweetening matter, and is presented in airtight containers. The classification is nested within Chapter 4, pertaining to dairy produce. The defining characteristic for this subcategory is the packaging method, requiring that the product be sealed in a way that prevents air from entering, thus preserving its quality and extending its shelf life.

This category is distinguished from its sibling, 0402.99.30.00 ("Other"), by the explicit requirement of being packaged in airtight containers. While both cover "other" forms of concentrated milk and cream not otherwise specified, the "Other" sibling encompasses products in forms other than airtight containers, such as bulk packaging or non-airtight seals. Therefore, the critical differentiator for 0402.99.10.00 is the specific containment method.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Classification under this heading is final based on the product meeting the criteria of concentrated milk or cream with added sugar or sweetener, and being presented in airtight packaging. Examples of products that would fall here include condensed milk or evaporated milk sold in cans or similar sealed containers.
