This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for forming other elastomeric tubes not for tires
Specificity to pneumatic tire inner tubes required; general tube formers go to other subheadings.
If for extrusion-only without final molding step
Pure extruders for rubber fall under separate provisions if lacking forming/molding capability.
If when sold as complete tire assembly line component
Integrated systems may classify under machines for rubber treatment not elsewhere specified.
