Section 3 — Levy of additional duty equal to excise duty, sales tax, local taxes and other charges

2-minute view

Creates the major additional-import levy architecture. Sub-section (1) addresses the excise-equivalent additional duty for like articles; sub-section (5) contains the legacy sales-tax/VAT counterbalance mechanism; sub-sections (7) and (9) provide the imported-goods IGST and compensation-cess framework, with valuation rules in the connected sub-sections and Customs Act machinery applied through sub-section (12).

Statutory position and legal effect

For Section 3, the legal answer should be built in layers. First identify what the section itself does; second identify the Schedule, notification, rule or investigation record that activates it for the goods and date; third reconcile that result with the Customs Act assessment machinery. This avoids a frequent customs error: treating a statutory power, a tariff rate and an effective rate as if they were the same thing.

The material date matters because tariff lines, exemptions, origin rules and trade-remedy measures change independently. A defensible file should therefore retain the exact tariff extract and notification version used in the assessment. Where this page is marked historical or transitional, the section should be cited only for a period when it legally operated or for explaining the transition to the current framework.

From an evidence perspective, the strongest working paper is not a screenshot of a duty calculator. It is a reconciliation showing the declared tariff item, legal notes considered, statutory rate, effective notification serial, preference/origin basis, additional levies, trade-remedy measure if any, and the arithmetic from customs value to final duty. Section 3 should occupy its correct place in that chain.

Official text control: use the India Code/Gazette version of Section 3 and the Schedule or delegated instrument applicable on the transaction date. This page intentionally explains the law rather than reproducing a long unofficial bare-act extract.

Applicability, rights, obligations and decision workflow

1. Step 1. Compute customs value under section 14 of the Customs Act.
2. Step 2. Calculate BCD and other sums entering the Section 3 value base.
3. Step 3. Identify the correct Section 3 sub-section: excise-equivalent, IGST, compensation cess or another notified additional duty.
4. Step 4. Apply the valuation formula prescribed for that sub-section, including special retail-sale-price or warehoused-goods rules where relevant.
5. Step 5. Check the effective exemption notification and GST/cess rate for the like domestic supply.
6. Step 6. Keep BCD, SWS, IGST, cess and trade-remedy levies separate in the computation trail.

Post-GST imports commonly require Section 3(7) IGST analysis in addition to BCD. Section 3(9) compensation cess must be checked against the law and notifications applicable on the import date. Older CVD/SAD concepts remain relevant for historical matters and for categories where the underlying levy still operates; labels such as “CVD” must not be used without identifying the exact sub-section.

Thresholds, provisos, timelines and interaction with other law

The section must be read with the Customs Act, the tariff Schedules and any subordinate instrument that gives it transaction-level effect. Where the provision contains a power rather than a self-executing charge, no duty or obligation should be assumed without locating the notification, rule, agreement or investigation determination that activates the power. Historical provisions require the same material-date discipline.

Rate changes, classification changes and trade-remedy measures are different legal events. The file should say exactly which one occurred and should not infer the enabling provision merely from the fact that the landed duty increased or decreased.

Worked example

Imported machinery has customs value ₹10,00,000 and BCD of ₹1,00,000. If no other amount alters the statutory base, IGST is computed on the Section 3(8) aggregate rather than simply on the original invoice price. The worked file should show each layer and not merely a final blended percentage.

Professional result: document the legal route before doing the arithmetic. A short computation that identifies the correct provision and current notification is stronger than a long calculation based on an obsolete tariff or historical measure.

Evidence and compliance checklist

• Material date and customs event.
• Exact 8-digit tariff item and candidate headings considered.
• Relevant Section/Chapter/Subheading Notes and GRI reasoning.
• Statutory Schedule rate and effective exemption/preference rate.
• Current notification/rule/Finance Act extract with effective date.
• Section 3 additional levies and separate trade-remedy duty, if any.
• Origin/FTA support where a preferential rate is claimed.
• Assessment/order and calculation reconciliation retained with source links.

Common mistakes and professional traps

• Treating all additional customs duties as the same levy
• Applying GST rate to invoice value instead of the statutory import value base
• Ignoring exemption conditions under Section 3(12)/section 25 notifications
• Assuming old SAD/CVD treatment automatically applies after GST
• Using an old manual or judgment for a current tariff rate without checking later amendments.
• Quoting a four-digit HSN heading when the legal outcome turns on an eight-digit tariff item or a national note.
