N334307 · 2023-08-09 — The tariff classification of chitosan from India
The product under consideration is referred to as KITAE® fungicide. The product consists of 10 percent chitosan diluted in 90 percent vinegar (approximately 7 percent acetic acid in 83 percent water solution). KITAE® functions as a fungicide due to the disruptive effect on the wall of fungi created by chitosan, a natural polysaccharide. The vinegar is used as an inert solvent to dissolve the chitosan but does not contribute to the product’s fungicidal activity. The applicable subheading for the KITAE®, chitosan based, fungicide will be 3913.90.2090, Harmonized Tariff Schedule of the United…
N330860 · 2023-02-22 — The tariff classification of Arabinoxylan (CAS No. 9040-27-1) from Poland
The product is Arabinoxylan (CAS No. 9040-27-1), a polysaccharide derived from wheat straw. It is trademarked and marketed under the name Arrabina. It will be imported in powder form and sold to companies in the food and beverage industry. The applicable subheading for the Arabinoxylan (CAS No. 9040-27-1) will be 3913.90.2090, Harmonized Tariff Schedule of the United States (HTSUS), which provides for natural polymers and modified natural polymers, not elsewhere specified or included, in primary forms: other: polysaccharides and their derivatives: other. The general rate of duty will be 5.8…
N310660 · 2020-04-03 — The tariff classification of chitosan lactate (CAS# 66267-50-3) from China
The subject product is referred to as chitosan lactate, CAS# 66267-50-3. Chitin is derived from the exoskeletons of crustaceans. The chitin then undergoes de-acetylation to produce chitosan. The chitosan undergoes a further lactic acid reaction in order to produce chitosan lactate, a polysaccharide derivative of chitosan. The product is imported in the form of a tan to amber dry flake. It will be imported in 25 kilogram fiber drum and paper bags. You state that the chitosan lactate flake will be used in water treatment operations to remove contaminants from water in order to prevent pollution…
N274764 · 2016-05-04 — The tariff classification of Chitosan Powder from China
The merchandise at issue is identified as Chitosan Powder. Chitosan is a linear polysaccharide produced by the deacetylation of chitin, a natural polymer derived from the shells of crustaceans. The product is imported in the form of an off-white powder. The applicable subheading for the Chitosan Powder will be 3913.90.2090, Harmonized Tariff Schedule of the United States (HTSUS), which provides for Natural polymers (for example, alginic acid) and modified natural polymers (for example, hardened proteins, chemical derivatives of natural rubber), not elsewhere specified or included, in primary…
