N250852 · 2014-03-06 — Tariff classification of polyamide-4,6 glass reinforced black pellets from the Netherlands.
You provided descriptive literature, chemical formulas, chemical structures and resin samples for our review. Polyamide-4,6 [HN(CH2)4NH.OC(CH2)4CO]n with 10 carbon atoms is made by condensation polymerization of diaminobutane [H2N(CH2)4NH2] and adipic acid [HO2C(CH2)4CO2H]. PA-4,6 is similar to PA-6,6 [HN(CH2)6NH.OC(CH2)4CO]n with 12 carbon atoms in that both are made from a diamine and diacid. The difference is the diamine for PA-4,6 is diaminobutane [H2N(CH2)4NH2] and the diamine for PA-6,6 is hexamethylenediamine [H2N(CH2)6NH2]. Heading 3908 provides for polyamides. Subheading Note 1 (a)…
N236151 · 2012-12-17 — The tariff classification of sodium of polyaspartic acid (CAS-181828-06-8, 35608-40-6) from Canada.
, you requested a tariff classification ruling. You provided the CAS number, chemical formula, chemical structure and molecular weight of the product. Sodium of Polyaspartic Acid (PASP) is a biodegradable water soluble polyamide resin. The product will be imported as a yellow liquid in bulk 200 Liter plastic drums for use as a scale and corrosion inhibitor in industrial water treatment applications. The applicable subheading for sodium of polyaspartic acid (CAS-181828-06-8, 35608-40-6) will be 3908.90.7000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for:…
N223455 · 2012-07-11 — The tariff classification of Polyamide 41BR1 polyamide-6,6 with 2-3% polyamide-6 (CAS-24993-04-2) from various countries.
You provided CAS numbers and a copy of the EPA’s Polymer Exemption Guide Manual. The subject merchandise, trade name 41BR1, is a polyamide that results from the reaction of three monomers, namely: hexamethyldiamine (HMD) (CAS# 124-09-4), adipic acid (CAS# 124-04-9) and caprolactam (CAS# 105-60-2). These three monomers are reacted starting from their monomer state, and the reaction forms a random arrangement of monomers within the resulting polymer chain. For the subject product, concentrations of the monomers that react are 2-3% caprolactam, and the balance is essentially equal parts of HMD…
N223055 · 2012-07-11 — Tariff classification of a polycaprolactam amide based cooling agent from Japan.
, you requested a tariff classification. You provided a sample and percent by weight component breakdown for review. The sample consists of 65grams of a cooling agent sealed in a rectangular shaped paper pack measuring approximately 12 cm. long x 7 cm. wide x 1 cm. thick. The cooling agent is made of a polycaprolactam amide based polymer in gel form, a gelling agent and a stabilizer. The product is designed for use as a refrigerant / ice pack. When frozen and placed inside a cooling bag, the product helps keep the food inside the bag cool and fresh while it is outside the refrigerator. The…
N189679 · 2011-11-15 — The tariff classification of Jointmide 348 polyamide (CAS-68410-23-1) from Taiwan.
You provided MSDS and technical data sheets for our review. Jointmide 348 is described as a polyamide in amber liquid form consisting by weight of 65-80% polyamide resin (CAS-68410-23-1), 5-10% 2,2’-Bis(4-hydroxyphenyl) propane (CAS-80-05-7) and 15-25% diethylenetriamine (CAS-111-40-0) reaction products. The product is used as a curing agent for epoxide resins in the manufacture of putties, sealants and concrete primer coatings for the construction industry. The applicable subheading for Jointmide 348 polyamide will be 3908.90.7000, Harmonized Tariff Schedule of the United States (HTSUS),…
