Import Tips
• Confirm that your TPP is not mixed with other substances; if it contains additives or is part of a formulated flame-retardant blend, classification may shift to heading 38.13 or 38.24
• Provide a certificate of analysis showing purity above 95% to support classification as a separate chemically defined compound
• Check whether the product is on the Domestic Substances List; if not, a new substance notification may be required before import
