7607.19 - Other:

HTS code 7607.19 encompasses aluminum foil that is not backed by other materials, and which does not fall under the more specific description of "rolled but not further worked." This category serves as a residual classification for unbacked aluminum foil that has undergone processing beyond simple rolling, such as embossing, perforating, or treating the surface, but does not meet the criteria for any more granular subheadings.

Distinguishing this code from its sibling, 7607.11, is crucial. While 7607.11 specifically covers aluminum foil that has been rolled but not subjected to any further working, 7607.19 is for unbacked foil that has experienced additional operations. For instance, foil that has been cut to shape, patterned, or otherwise modified after the initial rolling process would typically fall here, provided it remains unbacked and not specifically enumerated elsewhere.

Within this category, further classification is provided by the subcategories. The specific subheading 7607.19.10.00 identifies etched capacitor foil, a specialized product used in electronic components. All other types of unbacked aluminum foil, not meeting the etched capacitor foil criteria, are classified under the residual "Other" subheading at the next level, awaiting specific product identification for import or export purposes.
