Hot Forming Forging Machines and Hot Hammers, NESOI

Heading 846211 is limited to closed die forging machines — those that use matched upper and lower dies that fully enclose the workpiece. Heading 846219 captures all other hot-forming forging machines and hot hammers, including open-die hammers, drop hammers, and upset forging equipment. The key classification question is whether the dies fully close around the workpiece; if not, 846219 is the correct heading.

Used industrial machinery generally requires standard commercial entry documentation — commercial invoice, packing list, and bill of lading — but large forging hammers may trigger EPA noise or environmental compliance review depending on end-use facility requirements. Additionally, if the machine contains hydraulic fluids or lubricants, importers should verify that those substances comply with applicable EPA regulations before shipment.
