Chemical Analysis of Imported Coal Without Proper Sampling Violates Section 18(b) of Customs Act

The SC held that the chemical analysis of imported coal was ultra vires Section 18(b) of the Customs Act as the samples were drawn without following IS 436 and in the absence of any authorized representative, contrary to law. The Court rejected the Revenue's contention that the importer was estopped from objecting since no representative was present during sampling. It emphasized that illegal sampling cannot be validated by estoppel and that Customs authorities must comply strictly with legal procedures. Consequently, the denial of exemption based on the flawed sample testing was set aside, and the decision was made in favor of the appellant.

ISSUES:

Whether imported coking coal with ash content below 12% is exempt from basic customs duty and auxiliary duties under relevant notifications.Whether the customs department was justified in rejecting the certificate of analysis issued by an independent internationally reputed inspection agency and conducting its own chemical tests.Whether the samples drawn by the customs authorities for testing were valid in law, given they were not drawn in accordance with Indian Standard IS 436.Whether the appellants are estopped from challenging the validity of samples drawn by customs on the ground that a representative was present during sampling.The scope and limits of the power of the proper officer under Section 18 of the Customs Act to subject imported goods to chemical or other tests.

RULINGS / HOLDINGS:

The exemption under the notifications applies to coking coal with ash content below 12%, and the certificate issued by the internationally reputed agency CASCO showing ash content at 9.8% was valid and not challenged by the department.The customs department's chemical analysis of the samples was "ultra vires Section 18(b) of the Customs Act" because the department never demonstrated any good prima facie reason to reject CASCO's certificate or to deem it necessary to conduct further tests.The samples drawn by the customs authorities were invalid as they were not drawn in accordance with IS 436, which prescribes detailed procedures for sampling coal, including minimum sample weights and sampling methods; the customs samples were insufficient and improperly handled.The appellants were not estopped from challenging the sampling process because no representative of the appellants was present at the time of sampling, and estoppel cannot be invoked against a violation of law; "there can be no estoppel against law."The power under Section 18 of the Customs Act to subject goods to chemical or other tests requires that the proper officer "deems it necessary" based on reasonable grounds and not mere suspicion, and such power must be exercised within legal restraints.

RATIONALE:

The Court applied the statutory provisions of the Customs Act, particularly Section 18, which allows provisional assessment and testing only if the proper officer "deems it necessary" based on reasonable grounds.The Court relied on precedents establishing that expressions like "deems it necessary" and "reason to believe" require an honest and reasonable belief supported by material facts, not arbitrary or subjective satisfaction.The Court referred to Indian Standard IS 436 for coal sampling, holding that where the statute or notification is silent on the method of testing, the Indian Standard Institution's method applies, as previously held in related judgments.The Court rejected the Tribunal's finding on estoppel, emphasizing the principle that illegal acts cannot be validated by acquiescence or presence of a third party, and that no representative of the appellants was actually present during sampling.The Court emphasized that the customs authorities must comply with prescribed legal procedures and cannot rely on defective samples or tests conducted without proper legal basis.
