All 8-Digit Codes Under HSN 2918
Classify the goods at eight digits before you quote a rate: the duty, the export policy and the RoDTEP rate are fixed line by line. Heading text: Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives.

Basic customs duty is the standard rate in the First Schedule to the Customs Tariff Act. An exemption notification or a trade agreement can lower the duty actually payable. RoDTEP is a percentage of FOB value for exports from the domestic tariff area.
GST Rate on HSN 2918
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 |
|---|---|---|---|
| 5% | Schedule I, S. No. 222 | 29 or 3808 93 | Gibberellic acid (chapter-wide entry) |
| 18% | Schedule II, S. No. 36 | 29 | All organic chemicals other than giberellic acid (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 2918
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.
One or more tariff lines of this heading were substituted by the Finance Act 2025 and 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 2918
Under Schedule 2 of ITC(HS) 2022 the 49 tariff items are marked: 46 Free, 3 not shown in the Schedule text. “Free” means no export authorisation is needed; a Restricted item needs one from DGFT, and an STE item moves only through the named State trading enterprise.
RoDTEP is notified for 46 of the 49 tariff items, at 0.7–1.2% of FOB value (Appendix 4R, for exports from the domestic tariff area). The scheme continues up to 31 December 2026 at the rates in force on 30 September 2026.
The rate was cut by half for one month in 2026 and then restored. A shipping bill dated from 23 February to 22 March 2026 carries the reduced rate.
