What is the term used to describe a product by its manufacturer?

The correct term for describing a product by its manufacturer is "Trade Name." This designation is specifically used to identify the branded version of a product that is marketed and sold by a specific company. Trade names are what consumers recognize and the names under which products are advertised and sold in stores, often reflecting the brand identity of the manufacturer. For example, Aspirin is a trade name for the pain-relief product made by Bayer.

In contrast, the other terms have different meanings. The "Chemical Name" refers to the scientific name that describes the chemical structure of the substance, providing detailed chemical information. The "Generic Name" is used to identify the active ingredient in the product, which can be used by various manufacturers. Lastly, a "Product Code" is typically a unique identifier assigned to a specific product but does not convey the brand or manufacturer in the way a trade name does.
