Ambiguous Lab Reports Can't Justify Seizure of Distillate Oil: Gujarat High Court Applies 'Most Akin' Test

Introduction

In a significant ruling for importers and customs authorities alike, the Gujarat High Court has set aside the seizure of imported Distillate Oil by the Directorate of Revenue Intelligence (DRI), emphasizing that ambiguous laboratory test results cannot serve as the sole basis for treating the goods as restricted diesel and denying their release. A Division Bench comprising Honourable Mr. Justice A.S. Supehia and Honourable Mr. Justice Pranav Trivedi delivered the common oral judgment on December 9, 2025, in a batch of Special Civil Applications (Nos. 12943, 14559, 14552, and 14562 of 2025), filed by Noya Infrastructure LLP, Sweven Impex, and One Chemical Company against the Union of India and other respondents. The court invoked the Supreme Court's "most akin" test for goods classification under the Customs Tariff Act, 1975, ruling that the imported cargo, declared as Distillate Oil, warranted release pending verification of end-use, rather than outright seizure based on inconclusive test parameters. This decision underscores the need for precise scientific evidence in customs disputes, particularly involving petroleum products, and highlights potential revenue implications while protecting legitimate trade.

The case arose from the detention and seizure of bulk liquid cargo imported via the vessel MT-Vayu at Pipavav Port, Amreli, Gujarat, in August 2025. The petitioners, engaged in trading industrial oils, challenged the DRI's actions under Section 110 of the Customs Act, 1962, arguing misclassification driven by a flawed test report from the Central Revenues Control Laboratory (CRCL). The ruling not only quashes the seizure memos but also directs provisional release upon filing end-use certificates, mirroring treatments in similar cases at Kandla Port. For legal professionals, this judgment reinforces procedural safeguards against arbitrary enforcement, potentially influencing future import classifications in the petroleum sector.

Case Background

The petitioners—Noya Infrastructure LLP, Sweven Impex, and One Chemical Company—are entities involved in the import and trading of industrial oils and related products. Noya Infrastructure LLP, in particular, has a history of over 100 successful imports of Distillate Oil since 2023, with only one prior detention resolved upon duty payment. Sweven Impex has imported the product around 30 times since September 2023, facing a single similar issue, while One Chemical Company was making its first such import. The disputed consignments arrived via Bill of Entry numbers 4161474, 4161518, 4161492, 4161496, 4161500, and 4161512, dated August 28, 2025, at Pipavav Port. Accompanied by a certificate of analysis from supplier Chevron General Trading LLC confirming the goods as Distillate Oil, the cargo was transferred to Customs Bonded Storage Tank No. T-307 on August 1, 2025.

The dispute escalated when DRI officers, suspecting mis-declaration, conducted a panchnama and drew triplicate representative samples from the tank in the presence of petitioners' representatives, customs brokers, and independent surveyors. A Detention Memo followed on September 1, 2025, under Section 110 of the Customs Act, 1962, invoking possible mis-declaration. Despite completion of discharge operations and sample collection, the authorities delayed release, citing Public Notices from Mumbai and Kandla Customs Houses (Nos. 76/2020 and 14/2017). During the pendency of the writ petitions, a Test Report dated September 30, 2025, from CRCL, Delhi, emerged, concluding the samples did not meet Distillate Oil standards per IS 16731:2019, particularly the Cloud Point parameter (Sr. No. 14). This prompted a Seizure Memo on October 1, 2025, by the DRI Intelligence Officer, treating the cargo as diesel—a restricted item under Policy Condition No. 5, Chapter 27 of the Import Policy-ITC (HS) 2022.

The petitioners filed these writ petitions under Article 226 of the Constitution, seeking to quash the seizure and detention, arguing the test's ambiguity and seeking parity with similar releases at Kandla Port. The cases were heard analogously due to overlapping facts, with initial details drawn from SCA No. 12943/2025. The timeline—from import in August to judgment in December—highlights the urgency for importers facing bonded storage constraints and potential revenue losses from delayed trade.

The core legal questions revolved around:

(1) Whether the Test Report's findings justified seizure by conclusively proving mis-declaration as diesel;

(2) The applicability of the "most akin" test for classification under Rule 4 of the General Rules for Interpretation of the Customs Tariff Act; and

(3) Parity with prior CRCL clarifications and releases in analogous cases, ensuring non-discriminatory treatment.

Arguments Presented

The petitioners, represented by Senior Advocates Mr. S.N. Soparkar and Mr. Mihir Joshi, mounted a robust challenge to the seizure, centering on the Test Report's inherent ambiguity. They dissected the report's 14 parameters, noting that only the Cloud Point (measured at -6.2°C against the required max -16°C for IS 16731:2019) failed, while others like density (834.7 kg/m³ within 810-845 range), kinematic viscosity (3.6611 cSt within 2.0-4.5), and flash point (53.3°C above min 35°C) complied. The report's caveat—that samples exhibited "characteristics of diesel fraction with a small amount of heavier fraction of hydrocarbons"—was argued as inconclusive, not definitively classifying the cargo as Automotive Diesel Fuel (IS 1460:2025), especially since distillation at 95% recovery (389.5°C vs. max 360°C) only disqualified it from automotive diesel, not marine distillate use.

Drawing parity, the petitioners highlighted identical cargoes at Kandla Port, where CRCL's November 4, 2025, communication to the Assistant Commissioner clarified that deviations in parameters like diesel fraction were inconsequential, as products like High Flash High Speed Diesel (HFHSD, IS 16861), Automotive Diesel (IS 1460), Gas Oil (IS 17789), Distillate Marine Fuel (IS 16731), and Light Diesel Oil (IS 15770) all fall under "diesel fraction." Similar cloud point deviations (-11°C) led to provisional release at Kandla, applying the Supreme Court's "most akin" test from Gastrade International vs. Commissioner of Customs, Kandla (2025) 8 SCC 342. They refuted respondents' misuse allegations, noting clean import histories and no pending inquiries, urging quashing under the precedent's emphasis on ambiguity favoring importers.

In opposition, Senior Standing Counsel Mr. Anurag Oza for the respondents defended the seizure, asserting the Test Report unequivocally showed non-conformity with IS 16731:2019, particularly Cloud Point, and partial alignment with diesel characteristics (density 0.8203-0.8347 g/cm³ closer to diesel standards). He argued the cargo was mis-declared High Flash High Speed Diesel (HFHSD), restricted for import without licenses, leading to revenue loss via evaded duties and illicit GST input credits. End-use verification revealed supplies to transport agencies and construction firms using it as vehicle/excavator fuel, outside GST for diesel. Distinguishing from Kandla cases, Oza claimed material differences in parameters and petitioners' "behavioral footing," rendering Gastrade inapplicable. An additional affidavit detailed parameter charts, insisting no release without full compliance, as ambiguity did not negate preponderance of evidence toward diesel.

In rejoinder, petitioners dismissed misuse claims as unsubstantiated, emphasizing first-time or repeated clean imports, and reiterated CRCL's October 28, 2025, clarification that Cloud Point's relevance hinges on end-use and climate—not absolute disqualification for marine fuel in warmer conditions.

Legal Analysis

The Division Bench meticulously analyzed the Test Report's limitations, concluding the respondents overreached by extrapolating beyond its explicit findings. The report pinpointed only Cloud Point failure for Distillate Oil (IS 16731:2019) and, in one petition, distillation for Automotive Diesel (IS 1460:2025), but ambiguously noted "diesel fraction characteristics" without conclusive classification as restricted diesel. The court observed: "The Test Report is not definite that the Distillate Oil is in fact diesel, and the opinion in the report reflects that 'it has characteristics of diesel fraction with a small amount of heavier fraction of hydrocarbons.'"

Central to the reasoning was the "most akin" test from Gastrade International (supra), where the Supreme Court critiqued reliance on partial parameter compliance under preponderance of probability. In Gastrade , ambiguous tests failing key parameters like flash point and distillation rendered HSD classification unsafe without full 21-parameter conformity per IS 1460:2005. The Apex Court held: "In view of the ambiguity and lack of clarity in the expert opinion/laboratory test results, it would be unsafe to draw the inference that the Department had been able to prove their case even by applying the test of preponderance of probability merely because the samples conform to certain parameters." It prescribed Rule 4's "most akin" standard: assessing closest resemblance to specified goods, not mere similarity, especially amid overlapping petroleum standards.

Applying this, the Bench found the cargo "most akin" to Distillate Marine Fuel, as respondents failed to prove definitive diesel identity. Parity with Kandla was compelling: CRCL's November 4, 2025, letter equated all distillates as "diesel fraction," deeming akinness to HFHSD or Distillate Marine Fuel "of no consequence." Similarly, the October 28, 2025, clarification on Cloud Point noted its contextual relevance: "if the intended use of the sample under reference is as marine fuel in ships in the colder weather conditions, the cloud point requirement becomes significant. For other usage the cloud point is not a significant parameter." IS 16731 itself advises purchasers to verify cold flow suitability per voyage, not mandating uniform compliance.

The court rejected respondents' broader parameter infringements (e.g., density, viscosity), as the report confined disqualification to Cloud Point and diesel-like traits, with others satisfied. Distinguishing concepts, it clarified "characteristics" versus "conclusive identity," burdening authorities—not importers—with full testing resources. This aligns with Gastrade 's rejection of shifting onus, ensuring due process under Section 110. No other precedents were cited, but CRCL communications served as persuasive administrative guidance.

The analysis protects against revenue-driven overreach, mandating end-use certification for release, balancing trade facilitation with policy enforcement.

Key Observations

The judgment is replete with pivotal excerpts underscoring judicial caution against ambiguous evidence:

1. "From the pleadings as mentioned hereinabove, we are of the opinion that the respondents have travelled beyond the reasons mentioned in the Test Report. The Test Report definitely concludes by holding that 'Based on the above tested parameters, the sample under reference does not meet the requirement of Distillate Oil as per IS 16731:2019 with respect to parameter at Sr. No.14.'"

2. "The real test for classification, according to us, would be as to whether any goods or substance in question is 'most akin' or bears the closest resemblance or similarity to any of the specified goods mentioned under the headings and relative section or Chapter Notes under the Tariff Act, and not by applying the test of preponderance of probability." (Quoting Gastrade International )

3. "Thus, there is no definite conclusion with regard to the cloud point, and it depends upon the vessel being operated in specific areas... the cargo imported by the petitioner cannot be ordered to be seized on the basis of the parameter of cloud point, as it will be relevant only at the place, vessel, and time of use, and will depend on the end user."

4. "If the Department with all the resources at its command and access to various laboratory facilities could not get the samples tested in respect of all the 21 parameters, expecting the assesses-appellants to get the samples tested to show that these do not conform the specifications and are not HSD does not appear to be reasonable." (From Gastrade International , adopted)

5. "All the writ petitions succeed. The impugned Seizure Memos issued by the Intelligence Officer of the DRI are hereby quashed and set aside."

These observations emphasize evidentiary rigor and contextual classification.

Court's Decision

The Division Bench unequivocally ruled in favor of the petitioners, declaring: "All the writ petitions succeed. The impugned Seizure Memos issued by the Intelligence Officer of the DRI are hereby quashed and set aside. The action of the respondent authorities in detaining the imported bulk liquid cargo of Distillate Oil... is hereby quashed and set aside. We further direct the respondents to release the bulk liquid cargo of Distillate Oil imported through the vessels." To safeguard policy interests, the court mandated filing end-use certificates before customs authorities, akin to Kandla releases, ensuring verification of non-diesel usage.

Practically, this orders immediate de-bonding and release from Pipavav Port storage, alleviating petitioners' financial burdens from demurrage and lost trade opportunities. Broader implications are profound: it deters seizures predicated on partial or ambiguous tests, compelling DRI and CRCL to provide definitive classifications or risk judicial intervention. For future cases, the "most akin" test becomes a litmus for petroleum imports, potentially reducing litigation in overlapping standards like IS 16731 and IS 1460. Importers gain leverage in challenging detentions, while authorities must bolster lab protocols—perhaps standardizing full-parameter testing—to avoid revenue shortfalls from mis-declarations.

This ruling may spur policy reviews on diesel fraction ambiguities, impacting GST and duty collections estimated in crores annually. For legal practitioners, it signals a pro-trade stance in customs writs, emphasizing Gastrade 's enduring relevance and the need for end-use affidavits as provisional safeguards. Ultimately, it fortifies Article 226's role in upholding fair enforcement, benefiting Gujarat's import hubs like Pipavav and Kandla.
