Import Tips & Compliance
• Declare exact concentration and solvent type; solutions over certain strengths may trigger EPA pesticide registration requirements
• Include stability data to confirm the solvent is necessary for transport per Chapter 29 note (e), preventing misclassification
• Watch for anti-dumping duties on certain biocide imports; verify with CBP for country-specific rates
