The Customs, Excise and Service Tax Appellate Tribunal, Chennai, has held that a Board circular cannot impose a statutory limitation period absent in the parent statute, setting aside a rejection of drawback claims worth ₹6,52,423 where the conversion order remained unchallenged. The Tribunal ruled that Section 149 of the Customs Act, 1962, does not prescribe a three-month deadline for scheme conversion, and Circular No. 36/2010-Cus. dated 23.09.2010 could not create a jurisdictional bar to defeat substantive export benefits.
Background & Facts
The Dispute
Simpson and Co. Ltd., a Chennai-based manufacturer of diesel engines, secured a long-term supply contract with Cummins Inc., USA in 2011. To avail duty exemption on imported components, the appellant obtained Advance Authorisation License No. 0410127375 dated 24.08.2011. A subsequent change in customer specifications led to a mismatch between imported components and the part numbers in the Import Item List, resulting in certain components being cleared on duty payment while others used the Advance Authorisation. To neutralise the duty component on exported engines, the appellant sought conversion of shipping bills from the Advance Authorisation scheme to the Drawback scheme.

Relief Sought
The appellant sought setting aside of the impugned order, allowance of drawback claim of ₹6,52,423 for the three air export shipping bills, and consequential relief as per law.
The Legal Issue
The central questions were: (1) Whether the conversion of shipping bills from Advance Authorisation to Drawback scheme by the Commissioner of Customs (Exports) for air export bills was valid despite jurisdictional objections; (2) Whether Circular No. 36/2010-Cus. dated 23.09.2010 could impose a three-month limitation period for conversion applications not prescribed under Section 149 of the Customs Act, 1962; and (3) Whether an unchallenged conversion order could be reopened at the drawback sanction stage to deny substantive benefits.
Arguments Presented
For the Appellant
Ms. Shobhana Krishnan submitted that the request dated 26.03.2012 specifically covered the three impugned shipping bills, while the earlier 10.11.2011 request concerned different bills. The conversion order dated 30.07.2012 and brand-rate fixation of 28.09.2013 (revised 26.12.2013) remained unchallenged by the Department. Relying on Colossustex Pvt. Ltd. v. Union of India [2024 (387) E.L.T. 277 (Bom.)] and CC (Exports), Tuticorin v. Regin Exports [2026 (4) TMI 804 (Mad.)], counsel argued the three-month limit in Circular 36/2010 was unenforceable as Section 149 contains no such limitation. Citing Boving Fouress Ltd. v. CCE [2006 (202) E.L.T. 389 (SC)], ITC Ltd. v. CCE [2019 (368) E.L.T. 216 (SC)] and Estocorp India Pvt. Ltd. v. Union of India [2012 (275) E.L.T. 313 (Del.)], it was contended an unchallenged conversion order cannot be reopened at the sanction stage. Denial of drawback on procedural grounds despite valid conversion and brand-rate fixation would defeat the scheme's object.
For the Respondent
Smt. O.M. Reena contended the conversion by Commissioner of Customs (Sea) for air export bills was without jurisdiction, as the proper officer was the Principal Commissioner of Customs (Air Cargo). Under Circular 36/2010, conversion requests had to be filed before the proper officer within three months of the Let Export Order, which was not done. The drawback claims were therefore correctly rejected.
The Court's Analysis
The Tribunal examined the chronological record and found the request dated 26.03.2012, supplemented by documents on 24.04.2012, covered the disputed bills, whereas the 10.11.2011 request related to other bills. The impugned order erroneously conflated the two applications.
On the statutory interpretation question, the Tribunal held that Section 149 of the Customs Act, 1962, as applicable at the relevant time, permitted amendment after export on documentary evidence existing at the time of export but did not prescribe a three-month limitation. A circular issued by the Board cannot, by itself, introduce a statutory bar absent in the governing provision. The decisions in Colossustex and Regin Exports supported this position. The Tribunal further affirmed the settled principle that manuals, circulars and guidelines are administrative directions and cannot be regarded as law under Article 13 of the Constitution, citing Bidi Supply Co. v. Union of India (AIR 1956 SC 479, para 9), Collector of Malabar v. Erimmal Ebrahim Hajee (AIR 1957 SC 688, paras 8-9), and G.J. Fernandes v. State of Mysore (AIR 1967 SC 1753, para 12).
"A circular issued by the Board cannot, by itself, introduce a statutory bar that is not contained in the governing provision."
The conversion order dated 30.07.2012, having been passed after verification of all documents, remained unchallenged. The subsequent brand-rate fixation reinforced the legitimacy of the claim. The drawback claim could not be rejected by reopening the conversion order at the sanction stage without first dealing with it in accordance with law.
The Verdict
The appeal was allowed. The Tribunal set aside the impugned Order-in-Original No. 697/2016-AIR dated 01.08.2016 and directed the jurisdictional authority to process the drawback claim of ₹6,52,423 for the three disputed shipping bills (Nos. 6401581 dated 25.11.2011, 6505238 dated 02.12.2011, and 6564041 dated 07.12.2011) in accordance with law. The appellant is entitled to consequential relief as per law.
What This Means For Similar Cases
Circulars Cannot Create Statutory Limitations
Practitioners must challenge any rejection of drawback or scheme conversion based solely on Circular 36/2010's three-month deadline. Section 149 of the Customs Act, 1962 contains no such limitation, and the Supreme Court has consistently held that circulars are administrative directions, not law under Article 13. The Tribunal's reliance on Bidi Supply Co., Collector of Malabar, and G.J. Fernandes provides a robust doctrinal foundation to contest time-bar arguments rooted in circulars.
- Cite Colossustex (Bombay HC) and Regin Exports (Madras HC) as direct authorities that the three-month limit is unenforceable
- Argue that procedural circulars cannot override substantive statutory rights to export incentives
Unchallenged Conversion Orders Bind the Revenue
Once a conversion order is passed by a competent authority after verification and remains unchallenged, the revenue cannot reopen it at the drawback sanction stage on jurisdictional or limitation grounds. The line of authority from Boving Fouress (SC), ITC Ltd. (SC), and Estocorp (Delhi HC) establishes that such orders attain finality.
- Ensure conversion applications are filed with complete documentation to withstand scrutiny
- If conversion is granted, monitor for any departmental appeal within the prescribed period
- At sanction stage, object to any attempt to re-litigate conversion validity
Jurisdictional Objections Must Be Raised Timely
The Tribunal's finding that the 26.03.2012 request covered the disputed bills underscores the importance of precise pleading. Exporters should:
- Clearly identify all shipping bills sought to be converted in the initial application
- Submit missing documents promptly with covering letters referencing the original application
- Maintain a clear documentary trail linking each shipping bill to the conversion request
