Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vulcanized O-rings or seals
Finished vulcanized rubber seals and gaskets are articles of heading 4016.
If in plates, sheets, strip, rods, or simple profiles only
Complex ring shapes exceed 'profile shapes' in 4006.90.10; become 'other articles'.
If synthetic latex dispersions
Latex forms remain primary synthetic rubber under heading 4002.

Import Tips & Compliance
• Clearly mark as 'blanks for vulcanization' to avoid confusion with finished O-rings
• Include mold trial documentation showing softness indicative of unvulcanized state
• Watch for reclassification if blanks have been prevulcanized (latex form note)
