WCO Notes for Heading 2826

Sub-Chapter V

SALTS AND PEROXYSALTS, OF INORGANIC ACIDS AND METALS

GENERAL

Metal salts are obtained by replacing the hydrogen element in an acid by a metal or by the ammonium ion (NH₄⁺). In the liquid state or in solution, they are electrolytes giving a metal (or a metal ion) at the cathode.

In neutral salts all the hydrogen atoms are replaced by the metal, but acid salts still contain part of the hydrogen replaceable by metal; basic salts contain a greater quantity of basic oxide than is necessary to neutralise the acid (e.g., basic sulphate of cadmium (CdSO₄.CdO)).

Sub‑Chapter V covers metal salts of the acids classified in sub‑Chapter II (acids derived from non‑metals) or in sub‑Chapter IV (acid‑function metal hydroxides).

Double or complex salts.

Certain double or complex salts are specifically referred to in headings 28.26 to 28.41; for example, fluorosilicates, fluoroborates and other complex fluorine salts (heading 28.26), alums (heading 28.33), complex cyanides (heading 28.37). As regards double or complex salts not so specified, see the Explanatory Note to heading 28.42.

(A) FLUORIDES

Subject to the exclusions specified in the introduction to this Sub-Chapter, this heading covers the fluorides (i.e., the metal salts of hydrofluoric acid of heading 28.11).

The most important fluorides are :

(1) Ammonium fluorides : the neutral fluoride (NH₄F) and the acid fluoride (NH₄F.HF). These occur in deliquescent, colourless, toxic crystals, soluble in water. Uses include : as antiseptics (for preserving hides or wood); to control fermentations, (in lieu of hydrofluoric acid); in dyeing (mordants); for etching glass (mainly acid fluoride); for scouring copper; in metallurgy (to disintegrate ores, to prepare platinum), etc.

(2) Sodium fluorides : the neutral fluoride(NaF) and the acid fluoride (NaF.HF). Obtained by calcining natural calcium fluoride of heading 25.29 (fluorspar or fluorite) with a sodium salt. Colourless crystals, not very soluble in water, toxic. Like ammonium fluorides, they are used as antiseptics (for preserving hides, wood, eggs), to control fermentations, and for etching or frosting glass. They are also used in the manufacture of vitrifiable enamels or of parasiticides.

(3) Aluminium fluoride (AlF₃). Prepared from bauxite and hydrofluoric acid. Colourless crystals, insoluble in water. It is used as a flux in the enamel or ceramic industries and for purifying hydrogen peroxide.

(4) Potassium fluorides. Neutral potassium fluoride (KF.2H₂O) occurs in colourless, deliquescent, toxic crystals, very soluble in water. Also an acid fluoride (KF.HF). Same uses as sodium fluorides. In addition, the acid fluoride is used in the metallurgy of zirconium or of tantalum.

(5) Calcium fluoride (CaF₂). Prepared from the natural calcium fluoride (fluorite, fluorspar) of heading 25.29. Colourless crystals, insoluble in water; or may be in the gelatinous state. Used as a flux in metallurgy (particularly in the electrolytic preparation of magnesium from carnallite), and in the manufacture of glass or of ceramics.

(6) Chromium trifluoride (CrF₃.4H₂O). Dark green powder, soluble in water. In aqueous solution it attacks glass. Used as a mordant in dyeing.

(7) Zinc fluoride (ZnF₂). White powder, insoluble in water. Used for impregnating wood, in the preparation of enamels and in galvanising.

(8) Antimony fluorides. The action of hydrofluoric acid on antimony oxides gives antimony trifluoride (SbF₃), crystallising in deliquescent white needles, soluble in water, and antimony pentafluoride (SbF₅), a viscous liquid which dissolves in water with a hissing sound to form a hydrate (with 2 H₂O). These salts are used in ceramics, as mordants in dyeing or textile printing.

(9) Barium fluoride (BaF₂). Prepared from hydrofluoric acid and barium oxide, sulphide or carbonate. A white powder, sparingly soluble in water; toxic. Used as a pigment in ceramics or enamels, as an antiseptic in embalming, as an insecticide, etc.

This heading excludes non‑metal fluorides (heading 28.12).

(B) FLUOROSILICATES

Fluorosilicates are the salts of the hexafluorosilicic acid (H₂SiF₆) of heading 28.11.

(1) Disodium hexafluorosilicate (sodium fluorosilicate) (Na₂SiF₆). Prepared from silicon fluoride, a by‑product of the manufacture of superphosphates. White powder, only sparingly soluble in cold water. Uses include the manufacture of opaque glass and enamels, synthetic stones, anti‑acid cements, rat poisons, insecticides; the extraction of beryllium metal (electrolytic); the refining of tin by electrolysis; coagulating latex; as an antiseptic.

(2) Dipotassium hexafluorosilicate (potassium fluorosilicate) (K₂SiF₆). White, odourless, crystalline powder, slightly soluble in water, soluble in hydrochloric acid. Uses include the manufacture of vitreous enamel frits, ceramics, insecticides, synthetic mica; in metallurgy of aluminium and magnesium.

(3) Calcium hexafluorosilicate (calcium fluorosilicate) (CaSiF₆). White, crystalline powder; very slightly soluble in water; used as white pigment in ceramics.

(4) Copper hexafluorosilicate (copper fluorosilicate) (CuSiF₆.6H₂O). Blue, crystalline powder, soluble in water and toxic. Used for the production of mottled effects or as a fungicide.

(5) Zinc hexafluorosilicate (zinc fluorosilicate) (ZnSiF₆.6H₂O). Crystalline powder, soluble in water; reacts with calcium compounds to give a coating of calcium fluorides. Used for hardening concrete, for zinc electroplating, as an antiseptic or fungicide (wood infections).

(6) Barium hexafluorosilicate (barium fluorosilicate) (BaSiF₆). White powder used against the Colorado beetle and other insects, and to exterminate noxious animals.

(7) Other fluorosilicates. Magnesium fluorosilicate and aluminium fluorosilicate; like zinc fluorosilicate, these are used for hardening concrete. Chromium fluorosilicate and iron fluorosilicate are used in the dyestuff industry.

The heading does not include topaz, a natural aluminium fluorosilicate (Chapter 71).

(1) Trisodium hexafluoroaluminate (sodium hexafluoroaluminate) (Na₃AlF₆), synthetic cryolite, obtained as a precipitate on mixing aluminium oxide dissolved in hydrofluoric acid with sodium chloride, or by fusion of aluminium sulphate together with sodium fluoride. Occurs in whitish crystalline masses. It is used as a substitute for natural cryolite (heading 25.30) in the metallurgy of aluminium, in pyrotechnics, in enamels, in glass‑making or as an insecticide.

(2) Fluoroborates. Sodium fluoroborate (disinfectant), potassium fluoroborate (used in enamels), chromium fluoroborate and nickel fluoroborate (used in electro‑plating), etc.

(3) Fluorosulphates. In particular ammonium antimony fluorosulphate ((NH₄)₂SO₄SbF₃) or “Haen salt”; soluble crystals which corrode glass and metal. Used as a mordant in dyeing.

(4) Fluorophosphates, for example, those obtained from natural magnesium fluorophosphate (wagnerite) (heading 25.30) or aluminium lithium fluorophosphate (amblygonite) (heading 25.30).

(5) Fluorotantalates (obtained in the metallurgy of tantalum); fluorotitanates, fluorogermanates, fluoroniobates, fluorozirconates (obtained in the metallurgy of zirconium), fluorostannates, etc.

This heading includes metal fluoride oxides (of beryllium, etc.) and complex fluoride oxide salts but it excludes fluoride oxides of non‑metals (heading 28.12).

Fluoroformates, fluoroacetates or other organic complex fluorine salts are excluded (Chapter 29).

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.
