Wood pulp; obtained by a combination of mechanical and chemical pulping processes

HS code 470500 covers wood pulp produced through a combination of mechanical and chemical pulping processes. This type of wood pulp is a critical raw material for the global paper and paperboard industry, which in turn supports a wide range of downstream applications, from packaging and printing to tissue and specialty papers. As a key component in the manufacturing of various paper products, the wood pulp industry plays a vital role in the broader economy, enabling the production of essential goods and facilitating the flow of information and commerce.

The production of wood pulp under HS code 470500 involves a two-step process that combines mechanical and chemical pulping techniques. First, the raw wood material, typically softwood or hardwood logs, is mechanically ground or refined to separate the wood fibers. This mechanical pulping step helps to preserve the natural characteristics of the wood fibers. The resulting mechanical pulp is then combined with chemical pulp, which is produced through a chemical digestion process that breaks down the wood's lignin and separates the cellulose fibers. The blending of these two pulp types creates a versatile material that can be used in a wide range of paper and paperboard products.

The main inputs required for the production of wood pulp under HS code 470500 include raw wood materials, such as softwood or hardwood logs, as well as various chemicals used in the chemical pulping process, such as sulfur, sodium hydroxide, and other reagents. Additionally, the industry relies on specialized machinery and equipment for the mechanical and chemical processing of the wood, as well as energy sources to power the production facilities.

The primary output of the wood pulp industry under HS code 470500 is the pulp itself, which is then consumed by 470610 Pulp of wood or other fibrous cellulosic material; cotton linters pulp, 470710 (Recovered (waste and scrap) paper or paperboard), and 480100 Newsprint, in rolls or sheets, among other paper and paperboard manufacturing industries. The versatility of this wood pulp allows it to be used in a wide range of paper products, from newsprint and packaging materials to tissue and specialty papers.
