ELISA test kits denied exemption but extended limitation period under Section 28(4) wrongly applied without proving suppression

CESTAT New Delhi ruled on a customs duty dispute involving imported ELISA test kits. The tribunal upheld denial of exemption notification benefits for food testing kits, following precedent in Ilishan Biotech case. However, the tribunal found that extended period of limitation under Section 28(4) was incorrectly invoked, as the appellant had properly declared goods as diagnostic kits in Bills of Entry without suppressing material facts. The Principal Commissioner failed to adequately examine whether suppression warranted extended limitation period, particularly given contrary findings in an earlier order on identical facts. Consequently, penalty under Section 114A was also set aside since grounds for penalty and extended limitation are identical. The appeal was partially allowed - duty confirmation for normal period was upheld, but extended period duty and penalty were set aside.

ISSUES:

Whether ELISA test kits imported for food testing qualify as "diagnostic test kits" eligible for exemption under the relevant Customs Exemption Notifications.Whether the extended period of limitation under Section 28(4) of the Customs Act, 1962, can be invoked for demand of differential duty on the basis of alleged misdeclaration or suppression of facts.Whether penalty under Section 114A of the Customs Act, 1962, can be imposed for misdeclaration or suppression of facts in relation to customs duty liability.Whether the importer's claim of exemption for ELISA kits used for veterinary purposes requires separate consideration.

RULINGS / HOLDINGS:

ELISA test kits imported for food testing do not fall within the term "diagnostic test kits" as used in the exemption notifications, which are limited to kits related to diagnosis of illness in humans and animals; therefore, such food testing kits are not entitled to exemption.The extended period of limitation under Section 28(4) was wrongly invoked because the importer had declared the goods as food testing kits on the Bills of Entry, and mere incorrect claim of exemption does not amount to suppression or mis-statement of facts warranting extended limitation.Penalty under Section 114A of the Customs Act cannot be sustained as it is contingent upon the same conditions that justify invocation of the extended period of limitation, which were not met.The issue of exemption for ELISA test kits imported for veterinary use was not considered, as the importer did not raise this claim in the reply to the show cause notice nor during the appeal proceedings.

RATIONALE:

The Court applied the plain language of the Customs Exemption Notifications (No. 12/2012-Cus and No. 50/2017-Cus) and relied on the interpretation that the term "diagnostic test kits" is confined to those used for medical diagnosis in humans and animals, excluding kits for food testing.Precedent from a division bench decision was followed, which held that ELISA kits for food testing are not covered by the exemption, supported by reference to Harmonized System Nomenclature (HSN) explanatory notes and dictionary definitions of "diagnostic".The Court emphasized that invocation of the extended period of limitation under Section 28(4) requires proof of collusion, wilful mis-statement, or suppression of facts, which was absent as the importer had declared the goods' true nature on the Bills of Entry.Penalty under Section 114A was held to be dependent on the same conditions as extended limitation and thus could not be imposed without justification for extended limitation.The Court declined to consider the veterinary use exemption claim due to lack of prior notice or opportunity for the department to address the issue, underscoring procedural fairness.
