Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily a steam autoclave for general vulcanization
Machinery for heat/pressure treatment without tire specificity moves to Chapter 84.
If imported as replacement envelopes or curing chamber parts
Separate parts classification for tire molding equipment components.
If for industrial food packaging retreading unrelated to tires
Different end-use shifts to other rubber/plastics machines.
