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 2904
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 2904
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.
Whether an import is Free, Restricted or Prohibited is set line by line in ITC(HS) Schedule 1 (Import Policy), read with its General Notes on standards, quarantine and packaging. That policy line is not reproduced on this page; check it before you place the order.
Export Policy and RoDTEP for HSN 2904
Under Schedule 2 of ITC(HS) 2022 the 26 tariff items are marked: 26 Free. “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 26 of the 26 tariff items, at 0.7–1.3% 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.
