About Chapter 39
Chapter 39 of the Harmonized System of Nomenclature (HSN) is titled “Plastics and articles thereof”. It is part of Section VII, Plastics & Rubber, together with Chapter 40 (rubber and articles thereof).
The chapter is divided into 26 headings, from 3901 (polymers of ethylene, in primary forms) to 3926 (other articles of plastics and articles of other materials of headings 3901 to 3914). The headings with the most codes that people search for are other articles of plastics and articles of other materials of headings 3901 to 3914 (3926), polyacetals, other polyethers and epoxide resins, in primary forms (3907), other plates, sheets, film, foil and strip, of plastics (3921), plastic plates, sheets and film (3920) and articles for the conveyance or packing of goods, of plastics (3923).
Note 1 defines “plastics” for the whole tariff: the materials of headings 3901 to 3914 that can be formed, by moulding, casting, extruding, rolling or another process, into shapes they keep once the external influence is removed. It also counts vulcanised fibre as plastics.
Every heading is listed below. Under each are the codes that have their own page on Laabam One, 40 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 39: 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.
