Metal cans typically refer to cylindrical, seamed containers manufactured on high-speed can-making lines — such as food cans, beverage cans, and aerosol cans. Other metal containers (332439) cover a broader range including rectangular tins, pails, drums, and specialty shapes. The distinction affects both NAICS reporting and, for imports, the applicable HTS subheading, so precise product description is important when filing entry documents.

Container weight and cube efficiency make ocean freight economics challenging for empty cans and boxes, so domestic production or near-shore sourcing is common. When offshore sourcing is used, Section 232 tariff exposure on steel or aluminum content, minimum order quantities, and lead times for tooling and lithography are the primary cost and flexibility trade-offs importers must evaluate.
