Wood; engineered structural timber products, glue-laminated timber (glulam)
HS v2022 Code: 441881
About wood; engineered structural timber products, glue-laminated timber (glulam)
HS code 441881 covers engineered structural timber products, specifically glue-laminated timber (glulam). This industry plays a crucial role in the construction and building materials sector, providing high-strength, durable, and versatile wood products for a wide range of applications. Glulam is a popular choice for large-scale projects, such as bridges, commercial buildings, and industrial facilities, due to its superior structural properties and ability to span longer distances compared to traditional solid timber.
Production process
The production of glue-laminated timber involves the careful selection and preparation of wood veneers or boards, which are then glued together under high pressure to form the desired structural shape. This process allows for the creation of large, load-bearing timber elements that can be customized to meet specific design requirements. The use of advanced adhesives and precise manufacturing techniques ensures the structural integrity and durability of the final product.
Production inputs
The main inputs for the production of glue-laminated timber include high-quality softwood lumber, such as 440710 Wood; coniferous, sawn or chipped lengthwise, sliced or peeled, whether or not planed, sanded or end-jointed, of a thickness exceeding 6 mm and 440320 Wood; non-coniferous, in the rough, whether or not stripped of bark or sapwood, or roughly squared. Additionally, the industry relies on specialized machinery for cutting, gluing, and clamping the wood components, as well as adhesives and other materials necessary for the lamination process.
Production outputs
The primary output of HS code 441881 is engineered structural timber products, specifically glue-laminated timber (glulam). These products are widely used in the construction industry, particularly in the 441820 Wood; builders' joinery and carpentry, including cellular wood panels, assembled flooring panels, shingles and shakes and 441840 Wood; shuttering for concrete constructional work, shingles and shakes sectors, where they are valued for their strength, durability, and design flexibility.
