There are three companies involved (maybe more): The retailer, with which you have a contract, the importer and/or distributor, with which you don't, and the manufacturer, which is in another jurisdiction. Given that the manufacturer is usually somewhere abroad, which company will the legislature pick? There are two options, so I'd be shocked if the lawyers agreed on which option is better to write into the law.
