Import Tips & Compliance
• Provide a certificate of analysis confirming the PbO content and absence of other lead oxides to support classification under 2824.10.00
• Since ceramic glazes may contain other additives, ensure the product is shipped as pure lead monoxide, not a prepared glaze
• Check with the Canada Border Services Agency for any restrictions on lead-based ceramic materials
