HS Code for Non-coniferous sulphite pulp

Non-coniferous sulphite pulp is classified under HS code 4704.19 based on its chemical composition and manufacturing process. Chapter 47 of the Harmonized System governs pulp of wood or other fibrous cellulosic material. Within this chapter, heading 4704 is dedicated to chemical wood pulp produced via the sulphite process, excluding dissolving grades which fall under 4702. The classification further narrows down to subheading 4704.19, which specifies unbleached pulp derived from non-coniferous (hardwood) species. This distinction is critical because the physical properties and industrial applications of hardwood pulp differ significantly from those of softwood (coniferous) pulp. The sulphite process involves using various sulphites to extract lignin from wood chips, and when applied to hardwoods like eucalyptus, birch, or aspen without subsequent bleaching, the resulting product is strictly categorized here. This pulp is primarily used in the production of specialty papers and tissues where specific opacity and bulk are required.

Products Included

• Unbleached eucalyptus sulphite pulp
• Unbleached birch chemical wood pulp
• Aspen sulphite pulp for paper manufacturing
• Hardwood sulphite pulp, unbleached, non-dissolving grade
• Beech wood sulphite pulp

Common Misclassification

This product is frequently confused with HS code 4704.11, which is reserved for unbleached sulphite pulp derived from coniferous (softwood) trees like pine or spruce. Another common error is classifying it under 4704.29, which covers non-coniferous sulphite pulp that has been bleached or semi-bleached. Furthermore, if the pulp is of a high alpha-cellulose content intended for chemical derivatives, it must be classified under 4702.00 as dissolving grade pulp, regardless of the wood species or chemical process used.

FAQ

What is the HS code for non-coniferous sulphite pulp?

The HS code for unbleached, non-coniferous sulphite wood pulp (other than dissolving grades) is 4704.19.

What is the difference between sulphite and sulphate pulp?

Sulphite pulp (4704) is produced using a salt of sulphurous acid, whereas sulphate pulp (4703), also known as kraft pulp, is produced using sodium hydroxide and sodium sulphide. Kraft pulp is generally stronger and more common in global trade.
