(a) The obligation rests with the manufacturer of a product to determine whether a reasonable basis exists to conclude that a product that is the subject of a settled or adjudicated lawsuit is sufficiently different from other similar products to be regarded as a “particular model” under section 37 because it is “distinctive.” To determine whether a product is “distinctive”, the proper inquiry should be directed toward the degree to which a product differs from other comparable products in one or more of the characteristics enumerated in section 37(e)(2) and § 1116.2(c) of this part. A product is “distinctive” if, after an analysis of information relating to one or more of the statutory characteristics, a manufacturer, acting in accordance with the customs and practices of the trade of which it is a member, could reasonably conclude that the difference between that product and other items of the same product class manufactured or imported by the same manufacturer is substantial and material. Information relevant to the determination of whether a product is a “particular model” includes:
- (1) The description of the features and uses of the products in question in written material such as instruction manuals, description brochures, marketing or promotional programs, reports of certification of products, specification sheets, and product drawings.
- (2) The differences or similarities between products in their observable physical characteristics and in components or features that are not readily observable and that are incorporated in those products for safety-related purposes;
- (3) The customs and practices of the trade of which the manufacturer is a member in marketing, designating, or evaluating similar products.
- (4) Information on how consumers use the products and on consumer need or demand for different products, such as products of different size. In analyzing whether products are different models, differences in size or calibration afford the basis for distinguishing between products only if those differences make the products distinctive in functional design or function.
- (5) The history of the manufacturer's model identification and marketing of the products in question;
- (6) Whether variations between products relate solely to appearance, ornamentation, color, or other cosmetic features; such variations are not ordinarily sufficient to differentiate between models.
- (7) Whether component parts used in a product are interchangeable with or perform substantially the same function as comparable components in other units; if they are, the use of such components does not afford a basis for distinguishing between models.
- (8) Retail price. Substantial variations in price arising directly from the characteristics enumerated in section 37(e)(2) for evaluating product models may be evidence that products are different models because their differences are distinctive. Price variations imposed to accommodate different markets or vendors are not sufficient to draw such a distinction.
- (9) Manufacturer's designation, model number, or private label designation. These factors are not controlling in identifying “particular models”.
- (10) Expert evaluation of the characteristics of the products in question, and surveys of consumer users or a manufacturer's retail customers.
