HS Code for Coniferous sulphite pulp

The classification of coniferous sulphite pulp under HS code 4704.11 involves identifying both the chemical process used to extract the cellulose fibers and the state of the resulting pulp. Heading 4704 covers chemical wood pulp produced via the sulphite process, which involves cooking wood chips in a solution of sulfurous acid and a base (such as magnesium or calcium). This specific subheading, 4704.11, is designated for unbleached pulp derived from coniferous wood species like pine or spruce. To qualify for this code, the pulp must not be of 'dissolving grades,' which are high-purity pulps used for chemical derivatives like rayon. Unbleached sulphite pulp is characterized by its brownish color and is typically used in applications where high strength is required but brightness is not a primary concern, such as in certain types of specialty papers or as a component in paperboard. The distinction between unbleached and bleached (or semi-bleached) is vital, as the latter is classified under a different subheading. The pulp is usually presented in large sheets or rolls for further processing into paper products.

Products Included

• Unbleached pine sulphite pulp
• Unbleached spruce chemical wood pulp
• Coniferous sulphite pulp in sheets
• Softwood sulphite pulp for industrial paper
• Non-dissolving grade unbleached coniferous pulp

Common Misclassification

It is often confused with HS code 4703, which covers chemical wood pulp produced by the soda or sulphate (kraft) process. Additionally, if the pulp has been bleached or semi-bleached, it must be classified under HS code 4704.21 instead of 4704.11.

FAQ

What is the HS code for coniferous sulphite pulp?

The HS code for unbleached, non-dissolving grade coniferous sulphite pulp is 4704.11.

What is the difference between 4703 and 4704?

Heading 4703 is for sulphate (kraft) or soda pulp, while 4704 is specifically for pulp produced using the sulphite chemical process.
