Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not fabricated into structural members, sold as layered bamboo lumber
Plywood or veneered panels fall under Chapter 44 heading 4412 when not specifically fabricated for structural use.
If for non-structural decorative bamboo elements
Other articles of wood not specified elsewhere go to 4421 if lacking structural fabrication characteristics.
If assembled with metal connectors into trusses
Metal structures incorporating wood components shift to Chapter 73 for fabricated metal products.
