In re Niterra India Pvt. Ltd. (CAAR Delhi)
Customs Ruling on NOx Sensors: Niterra India’s Advance Ruling Application Rejected Due to Prior Judicial Precedent
In a significant customs ruling, the Customs Authority for Advance Rulings (CAAR) in Delhi rejected an application for an advance ruling filed by Niterra India Pvt. Ltd. The company sought clarification on the customs classification of NOx sensors it imports from Japan, a product used in vehicles and other machinery like gensets and earth-moving equipment. Niterra India proposed that the sensors should be classified under Customs Tariff Item (CTI) 9027.10.00, which covers “gas or smoke analysis apparatus,” and sought a ruling on its eligibility for a duty exemption under a specific India-Japan trade agreement.
The core of the dispute didn’t revolve around the product’s classification itself, but rather on the maintainability of the application. During a personal hearing on August 21, 2025, the CAAR noted that the issue of NOx sensor classification had already been decided by the Customs, Excise, and Service Tax Appellate Tribunal (CESTAT). Specifically, the court cited the case of Cummins Technologies India Private Limited v Commissioner of Customs (Import), which had ruled that NOx sensors were indeed classifiable under CTI 9027.10.00.
