Rules 17 to 21A take an investigation from the final finding to money in or out of the importer's account. Rule 17 sets the time and content of the final finding. Rule 18 gives the Central Government three months to levy duty. Rule 19 requires non-discrimination. Rule 20 says when duty starts, including limited retrospective cover. Rule 21 deals with differences between provisional and final duty, and rule 21A lets an importer apply to show it paid more than the actual margin of dumping.

This article reads the rules as amended up to the CBIC text dated 1 February 2021 (no amending notification found in CBIC's 2023-2026 lists; 2021-2022 not re-checked). Later notifications should be checked before you rely on the current text.

Rule 17: final findings

Time limit and contents (rule 17(1))

Within one year from the date of initiation, the designated authority determines whether the article is being dumped in India and submits its final finding to the Central Government covering: (i) export price, normal value and margin of dumping; (ii) for specified countries, whether imports cause or threaten material injury or materially retard an industry; (iii) a causal link, where applicable; and (iv) whether a retrospective levy is called for, with reasons and date of commencement. Clause (b) adds the recommended amount of duty which, if levied, would remove the injury, after considering Annexure III.

Two provisos adjust the year. The Central Government may, in its discretion in special circumstances, extend the period by six months. And where an investigation was suspended on a price undertaking under rule 15 and later resumed on violation, the suspended period is not counted.

Content of an affirmative finding (rule 17(2))

It must contain all information on facts, law and reasons, including supplier names (or supplying countries), a description sufficient for customs purposes, the margins and the methodology, injury considerations and the main reasons.

Individual margins and sampling (rule 17(3))

An individual margin is determined for each known exporter or producer. If the numbers of exporters, producers, importers or article types are so large that this is impracticable, the authority may limit findings to a reasonable number using statistically valid samples, or to the largest percentage of export volume that can reasonably be investigated, preferably in consultation with and with the consent of those concerned. A second proviso says an individual margin is determined for any exporter or producer not originally selected who submits necessary information in time, unless individual examination would be unduly burdensome. Rule 17(4): a public notice records the final findings.

Rule 18: levy of duty

Sub-ruleProvision
18(1)The Central Government may, within three months of publication of final findings, impose by Gazette notification anti-dumping duty on imports of the article covered, not exceeding the margin of dumping determined under rule 17. A sentence after sub-rule (1) was omitted by Notification No. 44/99
18(2)Where a percentage of export volume was selected, duty on exporters not examined must not exceed the weighted average margin for selected exporters (or, on a prospective normal value basis, the difference between weighted average normal value and export prices of those not examined). The Government disregards zero margins, margins below 2 per cent of export price and margins from the rule 6(8) circumstances. Individual duties apply to those who supplied necessary information
18(3)Where domestic industry was read under the rule 2(b) proviso, duty is levied only after exporters have had a chance to cease dumped exports to the area or give a rule 15 undertaking, and duty is not levied only on articles of specific producers supplying the area
18(4)If the final finding is negative, contrary to the evidence on which the investigation began, the Government must within forty-five days of publication withdraw any provisional duty

Rule 19: non-discrimination

Provisional duty under rule 13 and duty under rule 18 apply on a non-discriminatory basis to all imports of the article from whatever sources found dumped and, where applicable, causing injury, except imports from sources from which a rule 15 undertaking has been accepted.

Rule 20: when duty starts

Rule 20(1): duty under rules 13 and 19 takes effect from the date of its publication in the Official Gazette.

Rule 20(2): despite sub-rule (1):

  • (a) where provisional duty was levied and the authority recorded a final finding of injury, or of threat of injury plus a further finding that the effect of dumped imports without provisional duty would have led to injury, duty may be levied from the date of imposition of provisional duty;
  • (b) in the circumstances in section 9A(3) of the Customs Tariff Act, duty may be levied retrospectively from the date commencing ninety days prior to the imposition of the provisional duty.

Provisos: no duty is levied retrospectively on imports entered for home consumption before initiation of the investigation; on violation of a price undertaking (rule 15(6)), no retrospective duty on imports entered before the violation; and, by an added proviso, on violation of an undertaking the provisional duty is deemed levied from the date of violation or such date as the Central Government specifies.

Rule 21: refunds and differentials

  • 21(1): if the final duty is higher than the provisional duty already imposed and collected, the differential shall not be collected.
  • 21(2): if the final duty is lower than provisional duty collected, the differential is refunded to the importer.
  • 21(3): if provisional duty is withdrawn under rule 18(4), the provisional duty collected is refunded.

Rule 21A: importer's application on the actual margin

Rule 21A, inserted by Notification No. 6/2012-Cus. (N.T.) dated 19-1-2012, applies where an importer thinks it paid duty imposed under section 9A(1) or (1A) of the Act in excess of the actual margin of dumping on its goods.

  1. Application (21A(1)): the importer files before the designated authority in the form and with the documents the authority specifies.
  2. Deficiencies (21A(2)): a deficient application is returned within one month of receipt, pointing out the deficiencies; the importer may resubmit within one month thereafter.
  3. Initiation (21A(3)): on a complete application the authority initiates an investigation to determine the actual margin.
  4. Method (21A(4) to (6)): where export price is constructed, the authority takes into account changes in normal value, costs between importation and resale and movement in sale price reflected in subsequent selling price; no deduction for anti-dumping duties paid when conclusive evidence is provided.
  5. Recommendation (21A(7)): if duty paid exceeds the margin found, the authority recommends refund of the difference within nine months, and in no case more than 12 months, from receipt of an application complete in all respects.

An example: Sunrise Traders imports a chemical and pays duty. It believes the margin for its own supplier chain was lower, because its resale price moved with its costs. It files under rule 21A(1) in the specified form. If the authority finds the actual margin was lower than the duty paid, it recommends a refund of the difference to the Central Government within the rule 21A(7) period. Our legal dispute resolution team handles this kind of application.
