Hardener HS Code description

Hardener harmonized system code

Product Overview A Hardener, falling under the HS Code 3824, is a crucial chemical product used in numerous industrial applications to solidify or cure other materials. Typically, this product is in a viscous or liquid state and comprises reactive compounds that can initiate a curing process when mixed with suitable materials. Key attributes include viscosity, reactivity, and curing time, which can vary according to specific product formulations under this HS code. The HS Code 3824 encompasses Prepared binders for foundry molds or cores; chemical products and preparations of the chemical or allied industries, not elsewhere specified or included. Hardeners are extensively used in industries such as automotive, construction, and manufacturing for applications like paint formulation, adhesive production, and resin curing. The product's value proposition lies in its ability to enhance durability, longevity, and resistance properties of the materials it is used with, delivering a competitive advantage through improved product performance and lifespan. HS Code Classification & Trade Specifications The Hardener is classified under the full 6-digit HS Code 3824.90, which is further broken down hierarchically into Chapter 38 (Miscellaneous Chemical Products), Heading 24 (Prepared binders for foundry molds or cores; chemical products and preparations of the chemical or allied industries), and Subheading 90 (Other). Its classification under this code stems from its chemical composition and industrial use as a curing or hardening agent. Trade considerations for Hardeners include packaging in corrosion-resistant containers, preservation through appropriate storage conditions, and shipping requirements that align with the handling of chemical products. Quality standards for Hardeners typically include adherence to ISO standards for chemical products, and measures such as viscosity, reactivity, and curing time. This description complies with World Trade Organization (WTO) and customs documentation standards, aligning with international trade classification systems, and uses terminology familiar to trade professionals.

Hardener Chapter Note

1.- This Chapter does not cover : (a) Separate chemically defined elements or compounds with the exception of the following : (1) Artificial graphite (heading 38.01); (2) Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up as described in heading 38.08; (3) Products put up as charges for fire-extinguishers or put up in fire-extinguishing grenades (heading 38.13); (4) Certified reference materials specified in Note 2 below; (5) Products specified in Note 3 (a) or 3 (c) below; (b) Mixtures of chemicals with foodstuffs or other substances with nutritive value, of a kind used in the preparation of human foodstuffs (generally heading 21.06); (c) Products of heading 24.04; (d) Slag, ash and residues (including sludges, other than sewage sludge), containing metals, arsenic or their mixtures and meeting the requirements of Note 3 (a) or 3 (b) to Chapter 26 (heading 26.20); (e) Medicaments (heading 30.03 or 30.04); or (f) Spent catalysts of a kind used for the extraction of base metals or for the manufacture of chemical compounds of base metals (heading 26.20), spent catalysts of a kind used principally for the recovery of precious metal (heading 71.12) or catalysts consisting of metals or metal alloys in the form of, for example, finely divided powder or woven gauze (Section XIV or XV). 2.- (A) For the purpose of heading 38.22, the expression “certified reference materials” means reference materials which are accompanied by a certificate which indicates the values of the certified properties, the methods used to determine these values and the degree of certainty associated with each value and which are suitable for analytical, calibrating or referencing purposes. (B) With the exception of the products of Chapter 28 or 29, for the classification of certified reference materials, heading 38.22 shall take precedence over any other heading in the Nomenclature. 3.- Heading 38.24 includes the following goods which are not to be classified in any other heading of the Nomenclature : (a) Cultured crystals (other than optical elements) weighing not less than 2.5 g each, of magnesium oxide or of the halides of the alkali or alkaline-earth metals; (b) Fusel oil; Dippel's oil; (c) Ink removers put up in packings for retail sale; (d) Stencil correctors, other correcting fluids and correction tapes (other than those of heading 96.12), put up in packings for retail sale; and (e) Ceramic firing testers, fusible (for example, Seger cones). 4.- Throughout the Nomenclature, “municipal waste” means waste of a kind collected from households, hotels, restaurants, hospitals, shops, offices, etc., road and pavement sweepings, as well as construction and demolition waste. Municipal waste generally contains a large variety of materials such as plastics, rubber, wood, paper, textiles, glass, metals, food materials, broken furniture and other damaged or discarded articles. The term “municipal waste”, however, does not cover : (a) Individual materials or articles segregated from the waste, for example wastes of plastics, rubber, wood, paper, textiles, glass or metals, electrical and electronic waste and scrap (including spent batteries) which fall in their appropriate headings of the Nomenclature; (b) Industrial waste;(c) Waste pharmaceuticals, as defined in Note 4 (k) to Chapter 30; or (d) Clinical waste, as defined in Note 6 (a) below. 5.- For the purposes of heading 38.25, “sewage sludge” means sludge arising from urban effluent treatment plant and includes pre-treatment waste, scourings and unstabilised sludge. Stabilised sludge when suitable for use as fertiliser is excluded (Chapter 31). 6.- For the purposes of heading 38.25, the expression “other wastes” applies to : (a) Clinical waste, that is, contaminated waste arising from medical research, diagnosis, treatment or other medical, surgical, dental or veterinary procedures, which often contain pathogens and pharmaceutical substances and require special disposal procedures (for example, soiled dressings, used gloves and used syringes); (b) Waste organic solvents; (c) Wastes of metal pickling liquors, hydraulic fluids, brake fluids and anti-freezing fluids; and (d) Other wastes from chemical or allied industries. The expression “other wastes” does not, however, cover wastes which contain mainly petroleum oils or oils obtained from bituminous minerals (heading 27.10). 7.- For the purposes of heading 38.26, the term “biodiesel” means mono-alkyl esters of fatty acids of a kind used as a fuel, derived from animal, vegetable or microbial fats and oils whether or not used.
