GST

GST Rate on HSN 2939

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 rateEntryCodes namedGoods covered by the entry
5%Schedule I, S. No. 22229 or 3808 93Gibberellic acid (chapter-wide entry)
18%Schedule II, S. No. 3629All organic chemicals other than giberellic acid (chapter-wide entry)
18%Schedule II, S. No. 639Any ChapterGoods 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.

Import

Customs Duty on HSN 2939

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.

Duty changed by the Finance Act 2026

One or more tariff lines of this heading were substituted by the Finance Act 2026. The table above already shows the amended rate for those lines.

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.

Export Policy and RoDTEP for HSN 2939
