Aromatic Plasticizer Concrete Admixture from China
A liquid additive for cement and concrete mixes containing over 5% aromatic substances like alkylbenzene sulfonates to improve workability and reduce water demand. It falls under HTS 3824.40.10.00 due to its high aromatic content used as a prepared additive for concretes. This ensures better flow and strength in construction applications.

Import Tips
• Verify aromatic content via lab analysis to confirm >5% threshold; obtain SDS with exact composition for CBP review
• Ensure labeling specifies use for concrete to avoid misclassification as general chemical
• Watch for VOC regulations in destination country
