In re Knest Manufacturers Pvt. Ltd. (CAAR Delhi)
In a significant ruling for the construction sector, the Customs Authority for Advance Rulings (CAAR), Delhi, has determined that imported Aluminium Formworks (moulds for concrete), whether with or without supporting accessories, are to be classified under Customs Tariff Item (CTI) 7610 as “Aluminium structures… and parts of structures.” This ruling, in the case of “In re Knest Manufacturers Pvt. Ltd.,” clarifies the classification of these essential construction components, distinguishing them from traditional moulds.
Knest Manufacturers Pvt. Ltd. sought an advance ruling on the classification of Aluminium Formworks, proposing CTI 84806000 (moulds for concrete). The applicant indicated that the product would be imported either with or without supporting components and would undergo further processing like cutting, barcoding, and welding before use in construction.
Deliberation and Key Distinctions
The CAAR’s decision hinged on understanding the precise nature and function of Aluminium Formworks in construction, differentiating them from “moulds.” The ruling meticulously analyzed definitions of “shuttering,” “formwork,” and “mould” from various sources, including Indian Standards IS: 6461 (Part V) ‘Formwork for Concrete’ and established dictionary definitions.
Key distinctions highlighted by the CAAR:
- Formwork (Shuttering) vs. Mould: While “formwork” is a broad term encompassing temporary structures for concrete, and “shuttering” often refers to the vertical temporary arrangements, a crucial distinction was drawn between “formwork” and “mould.” The CAAR observed that formworks/shuttering are temporary structures erected on-site for in-situ concrete casting, providing both shape and support to wet concrete until it hardens. In contrast, moulds are generally used off-site for pre-casting concrete elements. The ruling emphasized that the primary function of the applicant’s product is to provide both shape and support to the concrete on-site.
