Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as complete centrifuge rather than liner part
Centrifugal cleaning machines have provisions in 8421; parts follow accordingly.
If imported as generic plastic articles
Unspecified plastic parts default to Chapter 39 unless proven machinery-specific.
If for paper machine approach flow cleaners
Cleaners after pulp stage but before paper forming use paper finishing provisions.
