Import Tips

• Verify EPA registration and TSCA compliance as HCB is heavily restricted under pesticide laws; obtain prior import approval

• Include detailed chemical analysis certificates confirming ≥98% purity to avoid reclassification as a mixture

• Declare historical fungicide use in documentation but emphasize current industrial synthesis applications to meet end-use declarations
