In the complex machinery of industrial manufacturing, the line between legitimate production and 'clandestine removal'—the practice of manufacturing and selling goods off the books to evade taxes—is often drawn in the fine print of ledgers and the digital footprints of computer servers. For the Indian tax authorities, proving that a company has bypassed the excise duty system requires more than just suspicion or a collection of external notes; it requires a direct, unbreakable link between raw materials and finished products.

Recently, the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) in Kolkata issued a series of rulings that underscore this high evidentiary bar. Through three distinct cases, the Tribunal has signaled that the Department's reliance on third-party records, estimated input-output ratios, and improperly recorded statements is insufficient to sustain massive tax demands.
The friction often begins not with the taxpayer, but with the intelligence agencies. In one instance, the Directorate General of Central Excise Intelligence (DGCEI) launched an investigation into Super Smelters Limited (SSL) in Durgapur. This investigation yielded a cache of private records and computer-generated information that the Department believed pointed toward systemic tax evasion.
In the high-stakes world of tax enforcement, a statement can be a powerful tool, but it is not a magic wand.
From this investigation, the Department turned its sights toward North East Engineering Co. Pvt. Ltd., seeking to recover a central excise duty of Rs. 67,43,187, alongside interest and penalties. The core of the Department's argument rested on the idea that the information gathered from SSL provided a roadmap to North East Engineering's own unaccounted activities. However, the company stood firm, denying the allegations and arguing that the Department had failed to prove the actual receipt of any unaccounted raw materials. The Tribunal ultimately sided with the appellant, allowing the appeal and rejecting the demand.
Perhaps the most challenging hurdle for the Department is the attempt to use mathematical modeling to prove tax evasion. In the case of Steelex Electrocast Private Limited, the authorities alleged a massive operation of clandestine manufacturing and removal of M.S. billets without the payment of duty. The resulting demand was staggering: ₹4,62,01,119 in central excise duty, accompanied by interest and significant penalties, including a ₹3 crore penalty imposed on the company's director.
The Department's logic relied heavily on an input-output ratio—a calculation used to estimate how much finished product should have been produced based on the amount of raw material supposedly purchased. Steelex Electrocast challenged this, contending that such mathematical estimates are mere approximations and cannot serve as a substitute for reliable, direct evidence of actual production and clearance.

Beyond the math, there is the matter of how evidence is gathered. In the Steelex Electrocast dispute, the Department relied on statements recorded under Section 14 of the Central Excise Act, 1944. In the high-stakes world of tax enforcement, a statement can be a powerful tool, but it is not a magic wand. The Tribunal ruled that these statements could not be relied upon because the Department failed to comply with the mandatory requirements of Section 9D. Without following these specific legal protocols, the statements lost their weight, leading to the rejection of the Department's case.

A recurring theme across these legal battles is the use of 'third-party records'—notebooks, ledgers, or digital files belonging to other companies—to infer the wrongdoing of a target company. This was the central tension in the case involving SBIW Steels and its director.
SBIW Steels operated as a conversion agent for SAIL under a wet-leasing agreement, manufacturing TMT bars. The Commissioner of CGST and Central Excise sought to use third-party records to infer that the company was engaging in unaccounted production and clearance. The Department's theory was that these external documents revealed a hidden stream of goods moving outside the company's statutory accounts.
However, the Tribunal found that these third-party records were insufficient to bridge the gap between suspicion and certainty. To prove clandestine removal, the Department must demonstrate not just that a third party claims a transaction occurred, but that the transaction actually happened and that the goods were indeed cleared without duty payment.
In the case of SBIW Steels, the Tribunal allowed the appeals, ruling that the demand was built on a foundation of insufficient evidence. The decision reinforces a vital principle in tax law: the burden of proof lies with the Department, and they cannot rely on the uncorroborated notes of outsiders to build a case for massive tax liabilities.
As these cases conclude, the landscape for industrial manufacturing in India remains one of high scrutiny. The rulings from CESTAT Kolkata serve as a reminder that while the Department has broad powers to investigate, those powers are checked by the necessity of rigorous proof. Whether it is the failure to follow procedural mandates like Section 9D, the reliance on unverified third-party notebooks, or the attempt to substitute input-output ratios for physical evidence, the Tribunal has made it clear: in the eyes of the law, an estimate is not an observation, and a third-party note is not a fact.
