Import Tips
• Confirm the silicone rubber is vulcanized and cellular; if the sheets are simply cut to rectangular shape without further working, they may fall under 4008
• If they are die-cut to specific gasket shapes, they qualify as articles of 4016
• Keep technical data on temperature resistance for CBSA
