Import Tips

Verify chemical composition via SDS to confirm it's a compound plasticizer, not a primary ester under Chapter 29

Include technical data sheets proving use in rubber/plastic processing to avoid reclassification

Check REACH and TSCA compliance for phthalates due to regulatory scrutiny on plasticizers
