GST Rate on HSN 2829

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.

Import

Customs Duty on HSN 2829

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.
