Import Tips
• Verify supplier certification that the rosin is from gum exudation (tree tapping), not wood extraction, to confirm HTS 3806.10.0010 classification
• Include chemical analysis or pine species origin documentation to distinguish from tall oil rosin
• Check for ISO 9001 certification on purity (levopimaric acid content) to avoid misclassification as lower-grade resins
