Commercial description of polypropylene governs exemption, even where imported polymer has a distinct molecular structure.

An exemption notification covering polypropylene under Chapter 39 was interpreted by its generic commercial description rather than any restrictive sub-heading. The imported goods, marketed as VESTOLEN P 6502 and VESTOLEN P 6522, were described in manufacturer literature as polypropylene, including a high molecular weight and reduced crystallinity form. Although the department treated them as block copolymers with a different molecular structure and classification, they remained within Chapter 39 and Heading 39.02, and the notification did not exclude modified forms of polypropylene. On that basis, the goods were entitled to exemption and the denial of benefit was set aside.

Issues: Whether the imported goods marketed as VESTOLEN P 6502 and VESTOLEN P 6522, though treated as block copolymers, were eligible for exemption under Notification No. 227/76 as polypropylene falling within Chapter 39 of the Customs Tariff Act, 1975.

Analysis: The notification granted exemption to polypropylene for goods falling within Chapter 39 without specifying any sub-heading. The manufacturer's literature described the goods as polypropylene marketed under the trade name VESTOLEN P, including polypropylene of high molecular weight and reduced crystallinity. Although the department distinguished block copolymer from polypropylene by molecular structure and sub-heading classification, the goods were still admitted to fall under Chapter 39 and Heading 39.02, and the notification did not confine the exemption to a particular sub-heading or exclude modified forms of polypropylene. The commercial description and marketing of the goods as polypropylene therefore supported their treatment as the notified product.

Conclusion: The goods were held eligible for exemption under Notification No. 227/76, and the denial of exemption was set aside in favour of the assessee.

Ratio Decidendi: Where an exemption notification identifies goods by their generic commercial description and not by a restrictive sub-heading, products marketed and understood in commerce as the notified goods are entitled to the exemption even if they possess a distinct polymer structure or fall under a different sub-classification within the same chapter.
