Import Tips
• Confirm the cylinders are not doped or cut into wafers, as that would shift classification to heading 38.18
• Keep documentation showing the silicon purity and unworked state for CBSA inspection
• If the cylinders are packaged with stabilizers or anti-dusting agents, ensure these do not alter the product's general use
