Diethylaminoethyl Methacrylate (DEAEMA) (CAS # 105-16-8)
The tariff classification of Diethylaminoethyl Methacrylate (DEAEMA) from China. The product that you wish to import is called Diethylaminoethyl Methacrylate (DEAEMA) (CAS # 105-16-8). You indicate that it contains as the main ingredient (DEAEMA) at 98% minimum. All other constituents present are impurities with the exception of MEHQ (CAS 150-76-5 at approx. 750 ppm.) You indicate that MEHQ is only added as an inhibitor. The imported bulk chemical will be used as a monomer to make water soluble polymers or other polymer products. Our research indicates that DEAEMA is a clear colorless liquid. It may polymerize exothermically if heated or contaminated. If polymerization takes place inside a closed container, the container may rupture violently. Further, we find that the added MEHQ is used as a polymerization inhibitor. The MEHQ is a necessary addition for safety or transport and is an allowable ingredient per the HTSUS, Chapter 29 Note 1.
