Import Tips

Obtain EPA registration for pesticide import and ensure labeling complies with FIFRA requirements including active ingredient concentration

Provide certificate of analysis verifying purity (typically >55% available chlorine) and dihydrate form to avoid misclassification

Avoid common pitfalls like importing without TSCA notification for new chemical uses; declare as pesticide, not general chemical
