Crowns, Closures, Seals & Other Packing Accessories (Industry Group)

Metal closures destined for food or pharmaceutical contact applications may need to comply with FDA regulations on food-contact materials, including restrictions on coatings and liners. Importers should obtain material safety data and supplier certifications confirming compliance with applicable FDA standards before entry.

Forged and stamped closures are classified under different NAICS and HTS subheadings, which can result in different base duty rates and varying exposure to trade remedy measures. Correctly identifying the manufacturing process is essential to accurate classification and cost forecasting.
