About Chapter 29
Chapter 29 of the Harmonized System of Nomenclature (HSN) is titled “Organic chemicals”. It is part of Section VI, Chemical Products, together with Chapter 28 (inorganic chemicals), Chapter 30 (pharmaceutical products), Chapter 31 (fertilisers), Chapter 32 (tanning or dyeing extracts; tannins and their derivatives), Chapter 33 (essential oils, perfumes, cosmetics), Chapter 34 (soap, organic surface-active agents, washing preparations), Chapter 35 (albuminoidal substances; modified starches; glues; enzymes), Chapter 36 (explosives; pyrotechnic products; matches; pyrophoric alloys), Chapter 37 (photographic or cinematographic goods) and Chapter 38 (miscellaneous chemical products).
The chapter is divided into 42 headings, from 2901 (acyclic hydrocarbons) to 2942 (other organic compounds). The headings with the most codes that people search for are acyclic alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives (2905), phenols; phenol-alcohols (2907), saturated acyclic monocarboxylic acids and their anhydrides, halides (2915), compounds with other nitrogen function (2929) and heterocyclic compounds with nitrogen hetero-atom(s) only (2933).
Note 1 limits the chapter, except where the context requires otherwise, to separate chemically defined organic compounds, mixtures of isomers of the same compound (mixtures of acyclic hydrocarbon isomers go to Chapter 27), and the products of headings 2936 to 2939 and 2941, whether or not chemically defined.
Every heading is listed below. Under each are the codes that have their own page on Laabam One, 31 codes in this chapter, each with its full classification: its chapter, heading and sub-heading, and the codes beside it.
Every code in this chapter begins with 29: four digits make a heading, six a sub-heading, and eight a tariff item of India's Customs Tariff. How many of those digits a GST tax invoice shows depends on the business, not the goods: under Notification No. 78/2020 – Central Tax, from 1 April 2021, four digits where aggregate turnover in the previous financial year was up to ₹5 crore, and six above it. Up to ₹5 crore, the code may be left off invoices to unregistered buyers.
No GST rate is shown here. GST rates were revised in September 2025, and a rate appears on this site only once it has been checked against the CBIC rate notifications.
