Materials, not of metal, for building and construction; rigid pipes, not of metal, for building; asphalt, pitch, tar and bitumen; transportable buildings, not of metal; monuments, not of metal.
Trademark applications and registrations in Class 19 over the past 15 years.
Class 19 encompasses non-metallic building and construction materials, including rigid pipes, asphalt, pitch, bitumen, and transportable buildings. The class serves a specialized but commercially significant segment of the construction and building products industry.
Major filers such as James Hardie, CertainTeed, and Eagle Materials represent the class's core constituency: manufacturers of siding, roofing, cement board, and other structural products. The class also includes monuments not of metal — a detail relevant to memorial and stone-working companies. Transportable buildings not of metal, covering prefabricated structures and modular construction units, have become an increasingly active filing area as the modular building industry expands.
The boundary between Class 19 and neighboring classes creates frequent classification challenges. Metal building materials belong in Class 6, not Class 19 — the metal versus non-metal distinction is the primary dividing line. Insulating materials fall under Class 17, even when used in construction applications. Cement preservatives and other chemical additives for building materials are classified in Class 1. Applicants should note that the class covers materials for building, not construction services, which belong in Class 37.
Class 19 is closely related to Class 6 (metal building materials) and Class 37 (construction services), and building product companies often file across all three. The distinction between rigid pipes in Class 19 and flexible pipes in Class 17 is another common source of examiner inquiries. Brands in flooring should also consider whether their products are better classified in Class 27 for floor coverings installed over existing floors.
Class 19 includes mainly materials, not of metal, for building and construction.

Search TrademarksClass 6 covers metallic building materials (steel beams, metal roofing, aluminum siding). Class 19 covers non-metallic building materials (concrete, wood, brick, stone, plastic pipes for construction).
Transportable buildings not of metal are in Class 19. Transportable buildings of metal are in Class 6. If the structure is primarily metal-framed, it goes in Class 6.
Building flooring materials (tiles, wood planks for installation) belong in Class 19. Floor coverings placed on top of existing floors (carpets, rugs, mats) belong in Class 27.
Yes. Composite decking, engineered wood products, and other non-metallic building materials for outdoor construction belong in Class 19. The non-metallic material composition determines classification here versus Class 6 for metal decking.
Non-metal windows and doors for buildings belong in Class 19. Metal windows and doors belong in Class 6. If the product combines both materials, classification is based on the predominant structural material.
Concrete, stone, and quartz countertop materials sold as building materials belong in Class 19. However, a complete vanity or counter unit sold as furniture may be classified in Class 20. The distinction is raw material versus finished furnishing.
Non-metallic roofing shingles (asphalt, slate, clay tiles) belong in Class 19. Metal roofing materials belong in Class 6. Chemical roof coatings and sealants are classified in Class 1 or Class 2.
Building material manufacturers typically file in Class 19 (non-metal materials), Class 6 (metal materials), Class 17 (insulation), and Class 37 (construction and installation services). Adding Class 1 for chemical additives like concrete admixtures is also common.
Yes. Artificial stone, manufactured stone veneer, and cast stone products for building purposes are classified in Class 19. Natural unworked stone is also in Class 19, while stone monuments and statues belong here as well.
