Import Tips
• Submit GC-MS analysis reports verifying decyl chain purity to distinguish from general phthalates under 2917.39
• Include end-use declarations specifying industrial PVC applications to prevent scrutiny under consumer product regulations
• Package in UN-approved chemical drums; improper labeling often leads to CBP holds for hazardous material verification
