Customs Tariff, HSN classification and effective-duty repository

Finin2min customs tariff method — in 2 minutes

1. Describe the goods exactly as imported: material, function, composition, dimensions, model and presentation.
2. Identify plausible Sections and Chapters; read the binding Notes before selecting a heading.
3. Apply GRI 1 first and later GRIs only as needed.
4. Descend to the current Indian 8-digit tariff item under GRI 6.
5. Fix customs value under section 14 and the relevant rate date.
6. Read the First Schedule statutory BCD and then the live effective exemption/concession.
7. Compute SWS, AIDC, import IGST/cess and other levies on their respective legal bases.
8. Test FTA/PTA preference and origin compliance separately.
9. Check DGFT ITC(HS) import policy and allied agency conditions.
10. Check anti-dumping, countervailing or safeguard notifications independently.

2026 legal position that changes the research route

The Union Budget/Finance Act 2026 amended the First Schedule through tariffisation and new tariff items, with several changes effective from 1 May 2026 and others from different dates. This makes undated tariff databases risky for current imports. The material-date First Schedule and the notification chain should be saved in the assessment file.

For effective BCD, Notification 45/2025-Customs is now a central source and superseded Notification 50/2017-Customs together with several other exemption notifications. The repository therefore treats the statutory First Schedule and the effective notification as separate layers: one does not replace the other.

Classification authority — Welkin Foods (2026 INSC 19)

The Supreme Court’s 6 January 2026 judgment in Commissioner of Customs (Import) v Welkin Foods is integrated throughout the GRI layer. It reinforces the sequence from heading text and Notes through later GRIs. For professional use, the judgment should be read with the current First Schedule, because the Court’s interpretive principle and the tariff item in force on a later import date are distinct questions.

Current exemption and policy controls

• BCD: statutory First Schedule rate + Notification 45/2025-Customs/later amendments or another specific exemption.
• SWS: Finance Act 2018 section 110 plus specific SWS exemptions/reductions.
• AIDC: Finance Act 2021 section 124 and current commodity-specific notifications.
• Import IGST/cess: Customs Tariff Act section 3 and current GST/cess rate/exemption.
• DGFT: ITC(HS) Schedule I, policy conditions and later notifications.
• Origin: agreement-specific preference notification, rules of origin, proof of origin and statutory importer obligations.
• Trade remedies: operative customs notification, not merely a DGTR finding.

Professional evidence standard

A tariff conclusion is strongest when another reviewer can reproduce it from the file without guessing. Retain the product specification, competing headings, Note/GRI analysis, exact tariff extract, material-date exemption, valuation sheet, origin evidence, policy condition and remedy notification. If an amendment changes only one layer, the file should show exactly which computation changes and which legal conclusions remain unaffected.

Source hierarchy: what controls when two tariff references disagree

A defensible customs classification starts with the legal text applicable to the material date, not with a search-result description, a broker database or a previous Bill of Entry. The research file should distinguish the Customs Tariff Act, 1975 and its Schedules from notifications issued under the Act, the Customs Act, 1962, DGFT policy instruments and judicial decisions. These sources answer different questions and should not be blended into one undated “HSN rate”.

1. First Schedule / tariff text: establishes the statutory nomenclature and tariff rate for imported goods. Read Section Notes, Chapter Notes, Subheading Notes and the tariff text together.
2. General Rules for Interpretation: determine how headings and subheadings are selected. Later GRIs do not displace a classification already resolved by GRI 1.
3. Customs exemption or concessional-duty notification: may reduce the effective BCD if the goods, tariff item, condition, end-use, certificate and effective date are satisfied. It does not rewrite the underlying classification.
4. Section 3 and other levy provisions: determine import IGST, compensation cess or other additional-duty architecture on their own statutory bases.
5. DGFT ITC(HS) and allied laws: determine whether import is free, restricted, prohibited or conditional. A customs tariff item is not an import authorisation.
6. Preferential origin and trade-remedy instruments: may change the effective incidence for qualifying origin or impose an additional remedy for specified goods/exporters/countries. They must be tested independently.

Where a commercial database conflicts with a Gazette notification or the operative Schedule, the primary legal instrument controls. Where a court decision concerns an older tariff entry, preserve the classification principle but separately verify whether the later tariff text has changed.

Material-date control — the 2026 tariff changes

Finance Act/Budget 2026 changes make date control especially important. Tariffisation and new tariff lines did not all become relevant merely because a Budget proposal was announced. The working paper for each import should record the Bill of Entry date, the statutory rate date, the version of the First Schedule used, the commencement date of the relevant amendment and the effective dates of exemption or levy notifications. This protects against applying a 2026 tariff line retrospectively to a transaction governed by an earlier nomenclature.

The same discipline applies to exemptions. Notification 45/2025-Customs consolidated a major part of the effective BCD framework and superseded Notification 50/2017-Customs and other listed instruments. A legacy workbook that still treats Notification 50/2017 as the principal live exemption source can therefore produce a false answer even when its HSN classification is correct. The current notification, its amending chain, serial number, description and conditions should be captured as evidence.

Five questions to answer after the 8-digit tariff item is fixed

Classification dispute-prevention file

For high-value, recurring or technically complex imports, prepare a short classification memorandum before filing. It should identify the imported condition of the product, its objective characteristics, the strongest competing headings, the legal Notes that include or exclude those headings, the GRI path used, any relevant Supreme Court or tribunal authority and the current 8-digit tariff item. It should also explain why the closest competing classification was rejected. This is more useful in audit or litigation than a conclusion-only HSN screenshot.

• Freeze product literature, composition/BOM, drawings, photographs and model data as they existed on the import date.
• Do not rely on a supplier’s HS code without reproducing the Indian tariff analysis.
• Where the product is a part, accessory, set, mixture, composite machine or unfinished article, test the specific Section/Chapter Notes and the relevant GRI rather than using commercial terminology.
• For recurring imports, set a review trigger for tariff amendments, exemption changes, origin changes, technical-regulation changes and new trade-remedy measures.
• If classification uncertainty is material, evaluate the advance-ruling route before creating a large recurring exposure.
