About wood wool; wood flour

HS code 4405 covers a range of products derived from wood, including wood wool and wood flour. These materials have a wide variety of applications across various industries, making them an important part of the global trade landscape. Wood wool and wood flour are versatile products that find use in everything from construction materials to personal care products, contributing to the overall health and growth of the economy.

Production process

The production of wood wool and wood flour typically involves mechanical processing of wood raw materials. Wood is first broken down into smaller fibers or particles through a process of chipping, grinding, or shredding. The resulting material is then further refined and processed to achieve the desired consistency and properties, such as particle size, density, and chemical composition.

Production inputs

The main inputs required for the production of wood wool and wood flour include various types of wood, such as softwoods and hardwoods, as well as specialized machinery and equipment for the mechanical processing of the raw materials. Depending on the specific application, additional inputs like binders, coatings, or other additives may also be required.

Production outputs

The primary outputs of HS code 4405 are wood wool and wood flour, which find a wide range of applications. Wood wool is commonly used in the production of insulation materials, packaging, and absorbent products, while wood flour is used in the manufacture of 4411 Fibreboard of wood or other ligneous materials and 4412 Plywood, veneered panels and similar laminated wood products, as well as in the formulation of various personal care and cosmetic items.
