HS v2017 Code: 4701
About wood pulp, mechanical wood pulp
HS code 4701 covers the production of wood pulp, a crucial raw material for the paper and paperboard industry. Wood pulp is the primary ingredient in the manufacture of various paper products, from newsprint and writing paper to packaging materials. This industry plays a vital role in the global economy, supporting downstream industries and meeting the growing demand for paper-based products.
Production process
The production of wood pulp involves mechanical or chemical processes to separate the cellulose fibers from the wood. Mechanical pulping uses physical means, such as grinding or refining, to break down the wood into pulp. Chemical pulping, on the other hand, utilizes chemicals like sulfite or kraft (sulfate) to dissolve the lignin that binds the cellulose fibers, resulting in a purer pulp product.
Production inputs
The main inputs for the wood pulp industry are raw wood materials, typically softwood or hardwood logs. Depending on the specific pulping process, various chemicals, such as sulfur compounds, sodium hydroxide, and anthraquinone, may also be required. Additionally, the industry relies on specialized machinery, including grinders, digesters, and pulp drying equipment.
Production outputs
The primary output of HS code 4701 is mechanical wood pulp, which is then consumed by 4802 Writing, printing or drawing paper and paperboard and 4803 Toilet or facial tissue stock, towel or napkin stock and similar paper of a kind used for household or sanitary purposes, among other paper and paperboard products. The wood pulp industry also generates byproducts, such as lignin and tall oil, which can be further processed and utilized in other industries.
