• N352093 · 2026-02-04 — The tariff classification of TFM aka 3-trifluoromethyl-4-nitrophenol (CAS No. 88-30-2) from China in bulk form

  We referred the information provided to our laboratory for review. We regret the delay. The subject merchandise is TFM also known as 3-trifluoromethyl-4-nitrophenol, CAS No. 88-30-2. You state that the imported product will consist of 100 percent of CAS No. 88-30-2. It will be imported in bulk form and will be used for sea lamprey control. You suggest classification in subheading 2908.99.2500, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Halogenated, sulfonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols: Other: Other: Other: Other…

• H306891 · 2025-03-11 — Modification of NY J81823, NY 891019, and NY 810507; Tariff classification of Propafenone Hydrochloride

  This is to inform you that U.S. Customs and Border Protection (“CBP”) has reconsidered New York Ruling Letters (“NY”) J81823, dated March 12, 2003, and issued to Ren-Pharm International, Ltd.; NY 891019 dated November 5, 1993, and issued to Interchem Corporation; and NY 810507, dated May 26, 1995, and issued to Interchem Corporation, regarding the classification of propafenone hydrochloride under the Harmonized Tariff Schedule of the United States (“HTSUS”). In each case, CBP classified propafenone hydrochloride in subheading 2922.50.14, HTSUS, which provides for “Oxygen-function…

• H304802 · 2023-03-14 — Affirmation of NY N304363; Classification of Lipacide C8G

  Specifically, CBP classified Lipacide C8G under subheading 2924.19.8000, HTSUSA (“Annotated”), which provides for “Carboxyamide-function compounds; amide-function compounds of carbonic acid: Acyclic amides (including acyclic carbamates) and their derivates; salts thereof: Other: Other.” We have reviewed NY N304363 in its entirety, along with the information in your request, and have determined it to be correct for the reasons set forth below. Lipacide C8G was described as follows in NY N304363: The instant product is called Lipacide C8G. You indicate that it is “a complex substance registered…

• N324059 · 2022-02-04 — The tariff classification of Bis[3-(Triethoxysilyl)Propyl]Disulfide from China.

  This ruling is an update to a previous ruling (N306696). The tariff classification has changed since the previous ruling was written. The subject product is called Bis[3-(Triethoxysilyl)Propyl]Disulfide (CAS # 56706-10-6). You indicated that it contains: Bis[3-(Triethoxysilyl)Propyl]Disulfide (90 %) with related Silanes (S4 - S8) making up the balance of the product. Our laboratory review indicates that the Silanes are impurities, left over from the chemical reaction, which are allowable based on HTSUS Chapter 29 Note 1. Bis[3-(Triethoxysilyl)Propyl]Disulfide also known as…

• N322547 · 2021-11-24 — The tariff classification of Tolperisone Hydrochloride (CAS No. 3644-61-9) in bulk form, from Mexico and Austria

  , you requested a tariff classification ruling. Tolperisone Hydrochloride is a muscle relaxant used for the symptomatic treatment of spasticity and painful muscle movements. It will be imported in bulk form and used in the manufacture of a finished drug product for the treatment of painful muscle spasms. You point out that Tolperisone Hydrochloride is a ketone, and you recommend classification in subheading 2914.39.9000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Ketones and quinones, whether or not with other oxygen function, and their halogenated,…
