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
