0402.91.70.00 - In airtight containers

This HTS category, 0402.91.70.00, specifically classifies milk and cream that are concentrated or contain added sugar or other sweetening matter, but are presented in airtight containers. The "Other" designation at this level indicates a catch-all for milk and cream falling within the broader scope of Chapter 4, beyond more specifically defined sub-classifications. The key defining characteristic here is the packaging – goods must be sealed to prevent air ingress to be classified under this code.

The primary distinction from its sibling category, 0402.91.90.00 (Other), lies solely in the method of packaging. While both cover "Other" milk and cream with added sugar or sweetening matter that is not otherwise specified, 0402.91.70.00 is exclusively for those products packaged in airtight containers. This implies that the airtight packaging is a crucial distinguishing feature for customs purposes.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification ends here. Examples of goods that would fall under this category include sweetened condensed milk or cream packaged in cans or retort pouches, where the hermetic sealing is integral to preservation and quality control. Classification relies on confirming the absence of added sugar or sweetening matter (as per the parent node) and the presence of the airtight packaging.
