Import Tips

Specify anhydrous vs dihydrate form in documentation; purity typically 60%+ available chlorine required for classification

Include end-use statement distinguishing pesticide vs general chemical applications to prevent reclassification

Ensure packaging prevents moisture absorption which could convert to dihydrate form during transit
