Import Tips

• Provide detailed chemical composition certificates (COA) confirming dinonyl orthophthalate content to avoid reclassification as general phthalates

• Ensure REACH and TSCA compliance documentation; include safety data sheets (SDS) showing industrial plasticizer use, not consumer applications

• Avoid common pitfalls by verifying purity levels (>95%) as impurities may trigger classification under broader 2917.39 headings
