Samples, testing & certification

 

Henna Manufacturers led by kirpal export overseas (KEO)

Never skip lab tests. Ask henna manufacturers for sample lots and request third-party testing for contaminants, heavy metals, and microbial levels. Certificates of analysis (CoA) and ISO or organic certificates (if claimed) must be verifiable. Samples are your rehearsal before the performance: treat them seriously and test under real-use conditions (patch tests, dye yield trials).
