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

GST Rate on HSN 2903

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 2903

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.

3 tariff items of this heading have a specific or compound duty (an amount per unit, or the higher of two) or a duty not shown here. Work those out from the quantity; the working above covers the lines charged on value alone.

Duty changed by the Finance Act 2025

One or more tariff lines of this heading were substituted by the Finance Act 2025. The table above already shows the amended rate for those lines.

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 2903

Under Schedule 2 of ITC(HS) 2022 the 81 tariff items are marked: 29 Free, 41 Restricted, 11 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.

Notification No. 9/2025-Central Tax (Rate), in force from 22 September 2025, names heading 2903 at 5% / 18%. The rate depends on the description in the entry, so match your goods to the entry before invoicing. Goods of the heading not covered by a specific entry take the residual 18% entry unless exempt.

The basic customs duty in the First Schedule to the Customs Tariff Act is Free – 7.5%. Social welfare surcharge at 10% of the basic duty and IGST at the GST rate are added on import. An exemption notification or a trade agreement can reduce the duty actually payable.
