N301560 · 2018-11-14 — The tariff classification of Tert-Butylaminoethyl Methacrylate (TBAEMA) (CAS # 3775-90-4) from China
The product that you wish to import is called Tert-Butylaminoethyl Methacrylate (TBAEMA) (CAS # 3775-90-4). You indicate that it contains as the main ingredient (TBAEMA) at 98% minimum. All other constituents present are impurities with the exception of MEHQ (CAS 150-76-5 at approx. 350 ppm.) MEHQ is added as an inhibitor to preven polymerization and reaction in transit and storage. The imported bulk chemical will be used as a monomer to make water soluble polymers or other polymer products. The MEHQ is a necessary addition for safety or transport and is an allowable ingredient per the HTSUS,…
N301561 · 2018-11-14 — 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…
N297851 · 2018-06-27 — The tariff classification of Various Chemical Compounds from China
You indicate they are all used for research at laboratories and universities. You provided the following information on the five items under review. Item 1 D-Raffinose pentahydrate (also known as Melitose or Melitriose, CAS # 17629-30-0) is a natural trisaccharide composed of galactose, glucose and fructose. It primarily serves as a carbon source for yeast as well as being an important component in some cryopreservation solutions. Additionally, it is known to improve digestion and increase the absorption of calcium. The product is imported as a white to off-white crystalline powder. The…
N286985 · 2017-06-14 — The tariff classification of 2-Amino-2-methyl-1-propanol (CAS # 124-68-5)
The subject product is a chemical product called 2-Amino-2-methyl-1-propanol (CAS # 124-68-5). It is also know as 2-Aminoisobutanol. You indicate that it will be used as a co-dispersant for pigments. It will be imported in bulk form. The applicable subheading for the 2-Amino-2-methyl-1-propanol will be 2922.19.9690, Harmonized Tariff Schedule of the United States (HTSUS), which provides for which provides for “Oxygen-function amino-compounds:Amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof: Other…Other.” The rate of duty…
