Import Tips

• Provide Safety Data Sheets (SDS) and technical specifications confirming accelerator purity and CAS number for customs verification

• Ensure proper Hazard Class labeling (often UN3077 Environmentally Hazardous Substance) and comply with TSCA pre-notification if applicable

• Verify REACH compliance for EU-origin products and avoid misclassification as basic organic chemicals under Chapter 29
