Douglas Fir Engineered I-Beam
This is a structural I-beam engineered from Douglas fir glulam flanges and a laminated veneer lumber web, designed for load-bearing applications in commercial building frameworks. It qualifies as builders' joinery and carpentry of wood under tariff item 4418.83.00 because it is a prefabricated I-beam made of wood, not a solid sawn timber product. The engineered composition and structural purpose align with the scope of this tariff item.
4418.83.00Glulam Wood I-Beam
This is an engineered I-beam made from glued laminated timber (glulam), with top and bottom flanges of multiple laminated wood layers connected by a thin plywood web. It is a prefabricated structural wood product used in building construction, falling under tariff item 4418.83.00 for I beams. The glulam construction provides high strength and stability for load-bearing applications.
4418.83.00LVL Flange I-Joist
This is a prefabricated I-joist featuring parallel strand lumber (LVL) flanges bonded to an oriented strand board (OSB) web, used in residential floor and roof framing. It is an engineered structural timber product that fits the description of I beams under tariff item 4418.83.00. The combination of LVL and OSB provides dimensional stability and load-bearing capacity.
4418.83.00OSB Web TJI Joist
This is a Trus Joist I-joist (TJI) with an oriented strand board web and machine stress-rated wood flanges, designed for long-span floor applications.
