Import Tips & Compliance
• Certify 99%+ water solubility and low heavy metals for hydroponic/agricultural classification vs technical grade
• Include solubility test results in documentation to distinguish from industrial phosphate chemicals
• Declare crystal size and purity level to avoid scrutiny as optical/purified chemicals excluded by Chapter Note 1
