Across its national industries Census lists 111 index entries; typical ones are building board (e.g., fiber, flake, particle) merchant…, asphalt and concrete mixtures merchant wholesalers, asphalt felts and coatings merchant wholesalers and architectural metalwork merchant wholesalers.

It splits into 4 more detailed codes. The largest by establishments is 42331 (Lumber, Plywood, Millwork, and Wood Panel Merchant Wholesalers) with 7,048.

Its more detailed codes are 42331 Lumber, Plywood, Millwork, and Wood Panel Merchant Wholesalers (7,048 establishments), 42332 Brick, Stone, and Related Construction Material Merchant Wholesalers (3,736 establishments), 42333 Roofing, Siding, and Insulation Material Merchant Wholesalers (3,581 establishments) and 42339 Other Construction Material Merchant Wholesalers (3,756 establishments).
