7607.11.30.00 - Of a thickness not exceeding 0.01 mm

This HTS category, 7607.11.30.00, specifically classifies aluminum foil that is not backed by other materials and has been rolled but not further worked. The defining characteristic of this classification is its precise thickness: it must not exceed 0.01 mm. This very thin gauge foil is typically used in applications where flexibility and minimal material usage are paramount, such as in certain types of packaging, electrical components, or specialized industrial processes.

It is crucial to distinguish this category from its sibling, 7607.11.60, which covers unbacked, rolled aluminum foil exceeding 0.01 mm in thickness. The demarcation lies solely in the upper limit of the foil's thickness, with 7607.11.30.00 encompassing only the thinnest of rolled, unbacked aluminum foils. Understanding this precise measurement is essential for accurate customs declaration.

As a leaf node, this category does not have further subcategories. Therefore, classification within 7607.11.30.00 is determined by confirming the aluminum foil is unbacked, has undergone only rolling, and its thickness is definitively not greater than 0.01 mm. Any deviation in these criteria would necessitate classification under a different HTS code.
