Import Tips

Certify silicone as synthetic rubber per chapter note 2 definition (vulcanizable, elongation/recovery test compliant)

Ensure strip width/thickness qualifies as 'strip' per chapter note 8 (regular geometric shape, simply cut)

Avoid packaging as sets with metal/hardware, which could trigger 4008.90 or Section XVI classification
