Import Tips & Compliance
• Include rheology data showing paste consistency without plasticizers (prohibited unless mineral oil-extended)
• CBP may require additive disclosure; limit to Note 5(b) emulsifiers/antioxidants
• Avoid declaring as solution if solvent > permitted levels, risking 4004 reclassification
