GST Rate on HSN 3912
GST on goods is fixed by the entries of Notification No. 9/2025-Central Tax (Rate), in force from 22 September 2025 and amended up to 30 April 2026. The rate shown is the total: half is central tax and half is State tax on a sale within a State, and the whole is charged as IGST on an inter-State sale or an import. Read the description in the entry, not only the code: the same heading can sit in two Schedules.
| GST rate | Entry | Codes named | Goods covered by the entry |
|---|---|---|---|
| 18% | Schedule II, S. No. 114 | 3901 to 3913 | All goods i.e. polymers; Polyacetals, other polyethers, epoxide resins, polycarbonates, alkyd resins, polyallyl esters, other polyesters; polyamides; Amino-resins, phenolic resins and polyurethanes; silicones; Petroleum resins, coumarone-indene resins, polyterpenes, polysulphides, polysulphones and other products specified in Note 3 to this Chapter, not elsewhere specified or included; Cellulose and its chemical derivatives, not elsewhere specified or included; Natural polymers (for example, alginic acid) and… |
| 5% | Schedule I, S. No. 319 | 39, 48 | Paper Sacks/Bags and bio-degradable bags (chapter-wide entry) |
| 18% | Schedule II, S. No. 639 | Any Chapter | Goods which are not specified in Schedule I, III, IV, V, VI or VII (residual entry) |
Goods of this heading that fall under no specific entry take the residual entry, unless they are exempt under the exemption notification issued with the rate notification.
Customs Duty on HSN 3912
An import pays three things: basic customs duty at the tariff rate, social welfare surcharge at 10% of that duty (unless exempted for the goods), and IGST at the GST rate on the value plus both duties. A registered importer takes credit of the IGST.
- Basic customs duty at
- Social welfare surcharge, 10% of the duty
- IGST at on value plus both
- Total duty and tax
- As a share of the value
Standard rates only: no exemption notification, anti-dumping or safeguard duty, or trade-agreement rate is applied, and the surcharge is taken at 10% although some goods are exempted from it. A registered importer takes credit of the IGST.
Three conditions at the port for food items
FSS Act compliance before clearance
Import of edible products is allowed only if the consignment meets the quality and packaging requirements of the Food Safety and Standards Act, 2006. Customs clears it after that is ensured.
Shelf life on the day of import
The product must have at least 60% of its original shelf life left, or three months before expiry, whichever is less, worked out from the dates on the label.
Notified food entry points only
Codes of this heading are in List B of Appendix V, so the goods can enter only through the ports, airports, land stations and ICDs in List A.
