The heterocyclic compounds covered by this heading are :

(A) Compounds containing an unfused furan ring (whether or not hydrogenated) in the structure.

This part includes, inter alia :

(1) Tetrahydrofuran. Colourless liquid.

(2) 2-Furaldehyde(furfural)*. Prepared by distilling cereal bran with sulphuric acid. Colourless liquid with a characteristic aromatic odour; it turns yellow and then brown when exposed to air. Used in the purification of mineral oils, for the preparation of synthetic resins, as a solvent for cellulose nitrate and varnishes, as an insecticide, etc.

(3) Furfuryl alcohol*. Colourless liquid which darkens when exposed to air. Reacts vigorously with concentrated mineral acids. Used as a solvent for cellulose nitrate, and for the preparation of varnishes and protective waterproof coatings.

(4) Tetrahydrofurfuryl alcohol. Colourless liquid.

(5) Sucralose* (1,6-Dichloro-1,6-dideoxy-β-D-fructofuranosyl-4-chloro-4-deoxy-α-D- galactopyranoside). Odorless, white to almost white crystalline powder. Artificial sweetener mainly used for medicine and food, especially for the treatment and diet of diabetic patients.

(6) Furan.

(B) Lactones*.

These compounds may be considered as internal esters of carboxylic acids with alcohol or phenol function, formed by elimination of water. The molecules may contain one or more ester functions in a ring. They are known as mono-, di-, trilactones, etc., according to the number of ester functions present. However, cyclic esters of polyhydric alcohols with polybasic acids are excluded (see Note 7 to this Chapter).

Lactones are fairly stable compounds, but are characterized by the ease with which the lactone ring can be opened using an alkali.

This part includes, inter alia :

(a) Coumarin (1,2-benzopyrone)*. This is the lactone of orthocoumaric acid. It crystallises in white flakes. It is used in perfumery, in medicine and for flavouring butter, castor oil, medicaments, etc. It also inhibits plant germination.

(b) Methylcoumarins. Same appearance as coumarin and also used in perfumery.

(d) Dicoumarol (dicoumarin). Crystals. Used in surgery as an anti-coagulant.

(e) 7-Hydroxycoumarin (umbelliferone). White crystals. Absorbs ultra-violet rays, hence its use in suntan lotions and creams.

(f) Dihydroxycoumarins (aesculetin and daphnetin). Crystals soluble in hot water.

Glucosides of dihydroxycoumarins (aesculin and daphnin) fall in heading 29.38.

(g) Nonalactone. Colourless or yellowish liquid; used in perfumery.

(h) Undecalactone. Similar appearance and same uses as nonalactone.

(o) Santonin. This is the internal ester of santonic acid extracted from santonica, the dried unexpanded flower heads of Artemisia cina. Odourless, colourless crystals; a fairly energetic vermifuge (anthelmintic).

(p) Phenolphthalein*. Obtained by the condensation of phthalic anhydride with phenol. A white or yellowish-white, odourless crystalline powder, soluble in ethanol. Reacts with alkalis to give a cherry-red colour which disappears when the solution is acidified. Used as a chemical reagent and as a laxative.

This group includes iodophenolphthalein, a yellow powder, also used as a laxative.

This heading, however, excludes :

(i) Sodium derivatives of phthalein tetrahalides (heading 29.18).

This part includes, inter alia :

(1) Benzofuran (coumarone). Found in light oils of the distillation of coal tar. A colourless liquid, used for the manufacture of artificial plastic materials (coumarone resins), etc.

(2) 1,3-Dioxolan.

(3) 1,4-Dioxan (diethylene dioxide), used as a solvent.

(4) 1,3-Dioxan.

(5) Safrole*. Obtained from sassafras oil. A colourless liquid which turns yellowish; used in perfumery and as a precursor for methylenedioxyamphetamine and methylenedioxymethamphetamine (see the list of precursors at the end of Chapter 29).

(6) Isosafrole. Obtained from safrole; used in perfumery and as a precursor for methylenedioxyamphetamine and methylenedioxymethamphetamine (see the list of precursors at the end of Chapter 29).

(7) Tetrahydrocannabinols.

(8) Piperonal (piperonylaldehyde or heliotropin) (CH₂O₂C₆H₃CHO)*. White crystals or flakes with an odour of heliotrope; used in perfumery and to flavour liqueurs and as a precursor for methylenedioxyamphetamine and methylenedioxymethamphetamine (see the list of precursors at the end of Chapter 29).

(9) Piperonylic acid.

Subheading Explanatory Note.

Subheading 2932.20

Lactones containing an additional hetero-atom, other than the oxygen atom of a lactone group (e.g., dilactone), in the same ring should not be classified in the subheadings for lactones. In such cases, the additional hetero-atom should be taken into account in determining the classification. Thus, for example, anhydromethylenecitric acid should be classified in subheading 2932.99 and not in subheading 2932.20.

If the ester function forms part of two or more rings and if one of these rings does not contain an additional hetero-atom (other than the oxygen atom of a lactone group), then the molecule should be considered as a lactone.

To be classified in subheading 2932.20, lactones must have the different lactone groups separated by at least one carbon atom at each end. However, this subheading does not include those products in which the carbon atoms separating and adjacent to the lactone groups form an oxo group (>C=O), an imino group (>C=NH) or a thioxo group (>C=S)*.

FAQs

What is HS code 2932?

HS code 2932 includes Organic chemicals - Heterocyclic compounds with oxygen hetero-atom(s) only..

How many sub-headings are there in HS code 2932?

There are 13 sub-heading(s) in HS code 2932.

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.
