9902.14.70 - Catalytic converter needled blanket mats of ceramic fibers, containing over 65 percent by weight of aluminum oxide and not over 3 percent of acrylic latex organic binder, of a basis weight greater than or equal to 1745 g/m2, measuring 10.0 mm or more in thickness; the foregoing presented in bulk, sheets or rolls, designed for use in motor vehicles of heading 8703 (provided for in subheading 6806.10.00).

This HTS category, 9902.14.70, specifically covers catalytic converter needled blanket mats composed of ceramic fibers. These mats are characterized by a high content of aluminum oxide (over 65% by weight) and a minimal presence of acrylic latex organic binder (not exceeding 3% by weight). Furthermore, they are defined by a substantial basis weight of at least 1745 g/m² and a significant thickness of 10.0 mm or more. The provision for these goods is made in bulk, sheets, or rolls, and crucially, they are designed for use in motor vehicles classified under heading 8703.

Unlike the primary HTS chapters that classify goods based on their inherent nature, such as live animals in Chapter 01 or mineral products in Chapter 25, this category falls under Section XXII, which deals with temporary legislation and special provisions. This means the classification is driven by specific trade policies or restrictions rather than the fundamental material composition of the goods themselves, even though the description details the material properties. The parent context of Chapter 99 highlights that this is a temporary measure, likely enacted for trade agreement purposes or under specific import restriction legislation, differentiating it from permanent tariff classifications.

As this is a leaf node within the HTS database, there are no further subcategories. The classification is considered final at this level based on the detailed physical and functional specifications provided in the description. Importers and customs officials will classify these specific catalytic converter blanket mats under 9902.14.70 if they meet all the enumerated criteria, particularly their composition, weight, thickness, and intended application in vehicles of heading 8703, which are passenger cars and other motor vehicles principally designed for the transport of persons.
