Import Tips

• Verify chemical composition via lab analysis to confirm it meets the exact definition of polyglycol esters of methylphosphonic acid

• Include Safety Data Sheets (SDS) and TSCA certification for US EPA compliance, as these are regulated flame retardants

• Avoid misclassification as generic plastic additives under 3824.99; specify phosphonate structure in invoices
