Not necessarily. The heading explicitly covers foil whether or not printed or backed with paper, plastic, or other materials, provided the aluminum layer itself does not exceed 0.2 mm. However, if the backing material becomes the essential character of the composite product, reclassification may be warranted — a determination that often requires a binding ruling from CBP.

Aluminum foil is subject to Section 232 tariffs. Additionally, antidumping and countervailing duty orders have been imposed on foil from specific countries at various times. Importers should check the current scope of any active orders and confirm whether their supplier's product and origin fall within scope before contracting.
