Introduction

In 1923, in his book titled “Interpretations of Legal History”, Roscoe Pound remarked that “law must be stable and yet it cannot stand still”. This statement underscores how law must keep evolving to avoid being fractured under the weight of a changing society. In India’s taxation landscape, the transition from the old administrative assessment system to a nimbler self-assessment system was one such evolutionary leap.

In the Union Budget of 2025-26, the Indian Customs law also followed suit with the insertion of Section 18A^[1] in the Customs Act, 1962 (“Act”). This insertion is seen as a derivative of the Supreme Court’s ruling in ITC Limited v. Commissioner of Central Excise, Kolkata IV (“ITC case”). This piece traces the inception of Section 18A, drawing parallels to Section 149 of the Act, and offers a critical analysis highlighting its limitations, and the road ahead. 

The ITC Decision: A Judicial Turning Point

The ITC case sought to determine the maintainability of a refund application under Section 27 of the Act when an order of assessment has not been challenged in appeal. Section 27 provides for a claim for a refund of duty or interest paid or borne by the assessee. The assessee may apply before the Assistant Commissioner of Customs or the Deputy Commissioner of Customs within a year from the date of payment of such duty or interest.

After thorough deliberation, the Supreme Court ruled that a claim for refund is rendered moot unless the order of assessment or self-assessment is modified in accordance with law. This ruling defined the contours of Section 27, and stated that setting aside an order of assessment or self-assessment, and reassessing the duty would not be within the ken of Section 27.

In the aftermath of the ITC case, Section 149 of the Act, which provides for “amendment of documents” gained considerable significance. As established by the Supreme Court, a modification to the order of assessment or self-assessment under Section 149 would entitle an assessee to claim a refund under Section 27. With the required framework already rooted in the Act, the necessity of the insertion of Section 18A raises legitimate curiosity.

Moving Beyond Section 149

As required by the ITC case, Section 149 already had a set framework for modifications in place. However, practical challenges in the framework necessitated a re-look, which eventually resulted in the birth of Section 18A.

Under Section 149, a modification post-clearance of goods required the assessee to produce documentary evidence before the Proper Officer. The documentary evidence must have been available at the time of clearance. Even if these criteria were met, the discretion of modification lay with the Proper Officer. There is precedent to show that this discretion has resulted in inordinate delays. Section 149 also acts as an impediment to the rectification of clerical, and inadvertent errors like discrepancy in the quantity of goods imported/exported. Such errors are identifiable only after the goods are cleared. Section 18A marks a transition from this system to a system of voluntary revision.

The Section 18A Framework

Section 18A aims to incentivise voluntary compliance, facilitate post-clearance modifications, and expedite the refund process. Under Section 18A, an assessee may revise an entry if any discrepancy is observed post-clearance. The revisionis required to be followed by self-assessment of the duty. If it is found that the duty was short paid, the assessee must pay the differential duty as per Section 28AA of the Act, which provides for interest on delayed payment of duty.

Similarly, if the duty has been paid or levied in excess, the revised entry itself is treated as an application for a refund under Section 27. This consolidation of the procedural fragments under one roof appears to have made the system of modification and revision of entries smoother.

This section also establishes a mechanism of checks and balances. The Proper Officer, through appropriate selection criteria based on risk evaluation, has the power to verify the revision and self-assessment of the assessee. If the revision and self-assessment turn out to be incorrect, the Proper Officer may re-assess the duty. If an assessee is already under an audit, search, seizure, or summons, they are barred from claiming relief under Section 18A.

Operationalising Section 18A

The Central Board of Indirect Taxes and Customs introduced the Customs (Voluntary Revision of Entries Post Clearance) Regulations, 2025 (“Regulations”) to operationalise Section 18A. The Regulations require the Proper Officer to verify the claims within ten working days from the date of generation of revised entry reference. They also do not prescribe an upper limit as to the number of times revision can be claimed with respect to the same document.

Critical Issues and Regulatory Gaps

While Section 18A appears solid on the surface, a closer look at the Regulations reveals some cracks in the foundation. Most glaringly, the Regulations do not prescribe a time limit for completing the verification of the revised entries. Revisions such as classification changes, which do not affect the duty, but are crucial for consistency and record accuracy, have not been addressed either.

Regulation 5(4)^[2] provides that a refund application shall first be verified for its completeness by the Proper Officer. If found to be complete, the Proper Officer shall issue an acknowledgement to the applicant. The explanation to this regulation specifies that interest on delay is to be granted from the date of acknowledgment or re-assessment, whichever is later. This puts the assessee in an adverse position if the Customs authorities cause a delay in closing the rectification.

Further, the Regulation 4(5)^[3], which deals with the manner of revision of entries, deems the date of generation of Acknowledgement Receipt Number (“ARN”) as the application date for refund claim under Section 27 of the Act. On the contrary, the explanation to Regulation 5(4) which provides for verification of revised entries, states that the application is considered to be received on the date of a complete application acknowledged by the Proper Officer, or the date of re-assessment, whichever is later.

Whilst as per Regulation 4(5), the refund claim under Section 27 of the Act is treated as filed upon ARN generation, the three-month period under Section 27A which provides for interest on delayed refunds, may begin only from a later date, contingent upon the date on which the complete application is acknowledged or when reassessment takes place, as stipulated by Regulation 5(4). This creates a situation of potential internal inconsistency within the Regulations and with Section 27A of the Act.

The Path Forward

As already discussed, there are cracks in the foundation in its present form. However, a little patchwork could easily reconcile the existing system with its intended objective.

The U.S. Customs & Border Protection (“CBP”) offers a system of automated correction, and liquidation by operation of law. An assessee can submit a Post-Summary Correction electronically via the Automated Commercial Environment(“ACE”). Further, under the 19 U.S. Code § 1504 (“U.S. Code”), if the CBP does not actively review or re-assess the duty within one year from the date of entry, it automatically liquidates by the operation of law at the rate assessed by the assessee.

A similar principle of certainty is necessary to eradicate the internal inconsistency within the Regulations and align them with Section 27A of the Act. Since delegated legislation cannot dilute a statutory entitlement, the explanation to Regulation 5(4) should align with Regulation 4(5), making the generation of the ARN the single, objective trigger for determining limitation and interest, much like the fixed “date of entry” that anchors liquidation under the U.S. Code.

In the EU, Article 22(3) of the Union Customs Code (“UCC”) provides that when an assessee files an application for a customs decision, the Customs authority must notify a decision within 120 days, which may be extended by another 30 days based on justifiable grounds. India could adopt a hybrid approach wherein the assessee may apply for a customs decision, such as post-clearance modification of entries, or non-tariff modifications like classification changes electronically via a portal like ACE. Further, there should be a statutory fixation of timeline within which the decision must be notified. If the Customs authorities fail to adhere to the timeline, the entry that inclines more in favour of the assessee must be finalised.

Final Thoughts

Section 18A is indisputably a step in the right direction, and in line with the evolving landscape of taxation in India. It emerged in the aftermath of the ITC case, as a result of which, Section 149 had become prevalent for the modification of entries. Since Section 149 was itself marred by certain limitations, it paved way for the introduction of Section 18A. Section 18A takes the burden off the Customs authorities, and allows for voluntary revision of entries by the assessee. It consolidates duty payments with interest and refund claims under a single provision. It also simplifies compliance and incentivises voluntary revision by the assessee.

Section 18A is operationalised by the Regulations. However, there are areas that need a re-look. Missing out on aspects such as fixing a time limit for the completion of verification of revised entries, classification changes, and the existing contradiction between regulations have kept Section 18A away from being a truly holistic and robust framework. Drawing inspiration from global best practices such as the ACE platform of the CBP, the U.S. Code, and Article 22(3) of the UCC could add to the completeness and strength of the provision, and provide a solid foundation to work with.
