Import Tips
• Include lot-specific Certificate of Analysis showing purity and moisture content to confirm monohydrate form
• Declare exact quantity and concentration; bulk powder vs dilute solutions affect documentation requirements
• Check for REACH compliance if importing from EU—Ninhydrin requires registration for volumes >1 ton/year
