Import Tips

Obtain TSCA pre-manufacture notice if synthesizing further derivatives in the US; verify EPA registration for any pesticide-related uses

Provide detailed purity certificates (GC-MS analysis) and SDS; declare as 'chemical intermediate, not for direct pesticide use' to avoid misclassification
