Import Tips & Compliance
• Document exact percentage of molybdenum compounds to distinguish from general anti-corrosion prep under 3824.99.40
• EPA registration may be required if marketed for US water treatment systems
• Avoid bulk packaging mislabeling as it could shift to waste headings if concentration exceeds limits
