Subject to the exclusions mentioned in the introduction to this sub‑Chapter, this heading covers silicates, metal salts of the various silicic acids, non‑isolated in the free state and derived from silicon dioxide (heading 28.11).

(1) Sodium silicates. Obtained by melting sand and sodium carbonate or sulphate. Their composition is very diverse (monosilicate, metasilicate, polysilicate, etc.), and their degree of hydration and their solubility vary with the method of manufacture and the degree of purity. Occur in colourless crystals or in powder, in vitreous masses (water‑glass) or in more or less viscous aqueous solutions. They deflocculate the gangues of ores and are used as flotation regulators. Also employed as fillers for manufacturing silicate soaps; as binders or adhesives in the manufacture of paperboard or agglomerated coal; as fire‑proofing materials; for preserving eggs; in the manufacture of non‑putrefying adhesives; as hardening agents in the preparation of corrosion‑resistant cements, of lutings or of artificial stones; for the manufacture of washing preparations; for pickling metals; as anti‑scaling products (see Explanatory Note to heading 38.24).

(2) Potassium silicates. Used for similar purposes to sodium silicates.

(3) Manganese silicate(MnSiO₃). Orange‑coloured powder, insoluble in water. Used as a ceramic colour and as a drier for paints or varnishes.

(4) Precipitated calcium silicates. White powders obtained from sodium or potassium silicates. Used for manufacturing fire‑proof pisés, and dental cements.

(5) Barium silicates. White powders used for manufacturing barium oxide and optical glass.

(6) Lead silicates. Occur as powder or in vitreous white masses; used as a glaze in ceramics.

(7) Other silicates, including commercial alkali metal silicates other than those mentioned above. These include caesium silicate (yellow powder, used in ceramics), zinc silicate (coating of fluorescent tubes), aluminium silicate (manufacture of porcelain and refractory products).

Natural silicates are excluded from the heading, e.g. :

(a) Wollastonite (calcium silicate), rhodonite (manganese silicate), phenacite (or phenakite) (beryllium silicate), and titanite (titanium silicate) (heading 25.30).

(b) Ores such as copper silicates (chrysocolla, dioptase), zinc hydrosilicate (hemimorphite), and zirconium silicate (zircon) (headings 26.03, 26.08 and26.15).

FAQs

What is HS code 2839?

HS code 2839 includes Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes - Silicates; commercial alkali metal silicates..

How many sub-headings are there in HS code 2839?

There are 3 sub-heading(s) in HS code 2839.

What is an HS Code and Why Does it Hold For Cross-Border Trade?

HS code is a standardized six-digit numerical classification system developed by the World Customs Organization (WCO) and acts as a universal language for simplifying the process of identifying and classifying traded products. They ensure consistent customs clearance, enable accurate duty calculation, and help identify relevant trade regulations. This simplifies the process for businesses, saving time, reducing risk, and promoting informed decision-making.

What are Controls and Why should Businesses Focus on Them?

In global trade, controls refer to a set of regulations and policies implemented by governments to manage the import and export of goods and services. These controls can take various forms, including tariffs, quotas, embargoes, export controls, and licensing requirements. Companies should prioritize understanding and adhering to them for compliance, reduced risk of legal issues, mitigating reputational damage, staying competitive, and building trust with governments.

What are Tariffs in Global Trade and Why should Businesses Focus on Them?

In global trade, tariffs are a type of tax levied by a government on imported goods. They act as a financial barrier to entry, increasing the overall cost of the imported product for domestic consumers and businesses. By understanding how tariffs work and their potential impact, companies can make informed decisions about pricing, sourcing, and market expansion, ultimately ensuring their competitiveness in the global marketplace.

What are FTAs in Global Trade and Why should Businesses Focus on Them?

In global trade, Free Trade Agreements (FTAs) are legally binding agreements between two or more countries aimed at reducing or eliminating barriers to trade between them. By understanding the terms of relevant FTAs and strategically incorporating them into their business plans, companies can enjoy reduced costs, expanded market access, and a more competitive edge in international trade.
