Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If uncorroded high-Cu Muntz
Fresh 94%+ Cu variants classify as premium alloy scrap.
If attached to vessel structures
Propellers on boats classify under 'vessels and floating structures' parts.
If heavy marine biofouling
Shellfish/clay encrustation makes it natural mineral waste.

Import Tips & Compliance
• Marine growth/salt requires power washing; provide cleanliness photos
• Zn loss from dezincification lowers Cu%; re-assay post-cleaning
• ITAR check for military propellers; demil certs mandatory
