Raw Sulfur Blocks from Japan
Large cast blocks of molten natural sulfur cooled in molds from Frasch recovery, unrefined. The casting is a simple cooling process, not a chemical change, and the sulfur is not sublimed, precipitated, or colloidal, so it falls under 2503.00.00.

Import Tips
• Ensure the blocks are not further processed, such as by melting or refining
• Provide CBSA with the Frasch process details and a purity certificate, and be ready to explain the cooling process if questioned
