Import Tips
• Ensure the silicon content is certified at 99.99% or higher by weight, as this determines classification under 2804.61.00
• Provide a mill test certificate or lab analysis to the CBSA to support the declared purity
• If the rods are doped for electronics, verify they remain in unworked form (e.g
• as drawn) to stay in this heading
