N272848 · 2016-03-10 — The tariff classification and status under the United States-Korea Free Trade Agreement of Ultramid® GWHS BK from Korea
The merchandise at issue, Ultramid® GWHS BK, is described as a heat-stabilized, black pigmented, fiberglass-reinforced polyamide-6 injection molding compound. The product consists of a polyamide-6 base polymer combined with fiberglass and a small proportion of heat-stabilizing agents, lubricants, and colorants. Based on the information provided, the polyamide-6 comprises more than half of the composition of the finished product. The product, imported in pellet form, is intended for use in applications such as the manufacture of automotive parts. The applicable subheading for the Ultramid®…
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)…
N226735 · 2012-07-19 — The tariff classification of Polyamide 41BR1 polyamide-6,6 with 2-3% polyamide-6 (CAS-24993-04-2) from various countries. Correction to Ruling Number N223455.
This replaces Ruling Number N223455 dated July 12, 2012, which contained a clerical error. Although correctly classified and described elsewhere in the ruling under the terms of the eo nomine subheading, namely Polyamides, in primary forms: Polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12, a typographical error was made in typing the HTSUS number, which should read 3908.10.0000, HTSUS. A complete corrected ruling follows. In your letter dated, June 25, 2012 you requested a tariff classification ruling. You provided CAS numbers and a copy of the EPA’s Polymer Exemption Guide Manual. The…
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…
H055375 · 2010-09-22 — Internal Advice Request No. 09/005; Classification of Cartarex 2L Liquid
This ruling is in response to Clariant’s request for Internal Advice, No. 09/005, dated August 25, 2008. In its request for internal advice, Clariant proposes classifying the Cartarex 2L Liquid under heading 3908, Harmonized Tariff Schedule of the United States (“HTSUS”) rather than under heading 3907, HTSUS. FACTS: The merchandise at issue is identified as “Cartarex 2L Liquid.” In its request for Internal Advice, Clariant describes its product as “a highly effective, fast working quenching agent for the fluorescent whitening agents used in the paper industry.” On its website, Clariant…
