Import Tips & Compliance
• Include technical data sheet showing <500 ppm MEHQ concentration typical for industrial polymerization inhibitor applications
• Label containers with GHS hazard pictograms (acute toxicity, skin corrosion) and Spanish/English safety data as required for chemical imports
• Verify TSCA registration status; unregistered new chemicals require EPA Premanufacture Notice (PMN) before import
