About wood; doors and their frames and thresholds, of tropical wood;

HS code 441821 covers the import and export of wood doors, frames, and thresholds made from tropical wood. This industry plays a crucial role in the global construction and furniture sectors, providing essential building materials for residential, commercial, and industrial projects. As the demand for sustainable and aesthetically pleasing wood products continues to grow, the 441821 industry has become an increasingly important part of the broader economy.

Production process

The production of wood doors, frames, and thresholds under HS code 441821 typically involves a multi-step process. First, tropical hardwood logs are harvested and transported to sawmills, where they are cut and milled into the necessary components. These components are then dried, sanded, and treated with preservatives to enhance their durability and resistance to weathering. Finally, the individual pieces are assembled into the final products, which may be further finished with stains, varnishes, or other coatings to achieve the desired aesthetic.

Production inputs

The main inputs required for the 441821 industry include tropical hardwood logs, such as 440349 Tropical wood, in the rough, as well as specialized machinery for cutting, shaping, and assembling the wood components. Additionally, the industry relies on adhesives, fasteners, and finishing materials to create the final products. Skilled labor, including carpenters, woodworkers, and assembly technicians, is also a critical input for this industry.

Production outputs

The primary outputs of the 441821 industry are wood doors, frames, and thresholds, which are then consumed by the 442110 Seats, 442190 Furniture, and 940610 Prefabricated buildings industries, among others. These wood products are used in a wide range of construction and renovation projects, from residential homes to commercial buildings and industrial facilities.
