Under Section 2(37) of the Consumer Protection Act, 2019, a "product seller," in relation to a product, includes a person who, in the course of business:

Section 2(37) of the Consumer Protection Act, 2019 defines "product seller," in relation to a product, as a person who, in the course of business, imports, sells, distributes, leases, installs, prepares, packages, labels, markets, repairs, maintains, or is otherwise involved in placing such product for commercial purpose, and includes a manufacturer who is also a product seller, or a service provider - but excludes a seller of immovable property, unless such person is engaged in the sale of constructed house or land. This broad, functionally defined category is central to the Act's product liability framework under Chapter VI, since a "product liability action" under Section 2(35) may be brought against the product manufacturer, product service provider, or product seller, holding the entire commercial chain accountable for harm caused by defective products, not merely the original manufacturer.
