0402.99.03.00 - In airtight containers

This HTS classification covers milk and cream, concentrated or containing added sugar or other sweetening matter, specifically those presented in airtight containers. This category falls under "Other" condensed milk and is further defined by its packaging, which is crucial for preservation and transport. The airtight packaging ensures product integrity and prevents spoilage, making it a key distinguishing factor for classification purposes.

This specific classification is differentiated from its sibling category, 0402.99.06.00, which encompasses "Other" milk and cream products that do not meet the specific criteria of being in airtight containers. Therefore, the presence or absence of airtight packaging is the primary determinant in distinguishing between these two codes at this level.

As a leaf node, 0402.99.03.00 does not have further subcategories. This means that any concentrated milk or cream product, with or without added sugar, that is packaged in airtight containers falls directly under this code. Examples would include evaporated milk or sweetened condensed milk supplied in cans, or similar products in other sealed containers designed for long-term storage and protection from external atmospheric conditions.
