Import Tips & Compliance

• 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
