Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the lid is part of a machine performing a specific function other than centrifugation
Parts of machines with specific functions not covered elsewhere are classified in heading 84.79.
If the lid is a simple fabricated metal article not identifiable as a centrifuge part
Other articles of iron or steel are classified in heading 73.26 when not parts of machines.
