HS Code for Non-coniferous kraft pulp

Classification under HS code 470319 is determined by the specific chemical manufacturing process and the botanical origin of the wood source. This code specifically covers chemical wood pulp produced via the soda or sulphate (kraft) process. To qualify for this subheading, the pulp must be derived from non-coniferous (hardwood) species such as eucalyptus, birch, poplar, or acacia. Furthermore, the 470319 designation is strictly reserved for unbleached grades—those that have not undergone chemical whitening treatments to increase their brightness. This material is primarily utilized in the production of high-strength industrial paper and paperboard where the natural brown color of the fibers is acceptable or even preferred for its aesthetic and structural properties. The "kraft" process, named after the German word for strength, involves the use of sodium hydroxide and sodium sulphide to dissolve the lignin that binds cellulose fibers together. This results in a pulp with high tear resistance and tensile strength. The classification excludes "dissolving grades," which are highly purified pulps used for chemical derivatives like rayon or cellulose acetate. The distinction between coniferous and non-coniferous is vital, as the fiber length and bonding properties differ significantly between the two, affecting the final paper's tear strength and opacity. Non-coniferous fibers are generally shorter, providing a smoother surface for printing while maintaining the structural integrity required for packaging materials.

Products Included

• Unbleached eucalyptus kraft pulp used for specialty packaging.
• Unbleached birch sulphate pulp for high-strength industrial liners.
• Unbleached acacia chemical pulp for corrugated medium production.
• Unbleached hardwood soda pulp for specific technical paper applications.
• Semi-chemical hardwood pulps that meet the sulphate process criteria.

Common Misclassification

It is common to confuse 470319 with 470329, which covers bleached or semi-bleached non-coniferous kraft pulp. The distinction lies entirely in the chemical treatment after pulping. Additionally, 470311 is often used incorrectly; that code is reserved for unbleached kraft pulp derived from coniferous (softwood) trees like pine or spruce. Importers must also ensure they do not use 470200, which is for chemical wood pulp of dissolving grades, regardless of the wood species or bleaching status.

FAQ

What is the HS code for Non-coniferous kraft pulp?

The HS code for unbleached, non-coniferous chemical wood pulp produced by the soda or sulphate process is 470319.

How does unbleached pulp differ from bleached pulp in classification?

Unbleached pulp (470319) retains its natural brown color and lignin remnants, whereas bleached pulp (470329) has undergone oxygen, chlorine, or peroxide treatments to achieve high brightness for white paper production.
