HS Code for Paper sizing agent

Paper sizing agents are classified under HS code 380992. This code is part of Chapter 38, which encompasses miscellaneous chemical products. Heading 3809 specifically covers finishing agents, dye carriers to accelerate dyeing or fixing of dyestuffs, and other products and preparations (for example, dressings and mordants) used in the textile, paper, leather, or like industries, not elsewhere specified or included. Subheading 380992 is reserved for those preparations used specifically in the paper or paperboard industry. Sizing agents are chemicals applied to paper during the manufacturing process to improve surface strength, printability, and water resistance. They can be applied internally (added to the pulp) or externally (surface sizing). The classification is based on the chemical preparation's function as a finishing agent within the specific context of paper manufacturing.

Products Included

• Alkyl Succinic Anhydride (ASA) sizing agents
• Alkyl Ketene Dimer (AKD) dispersions
• Rosin-based sizing preparations for paper
• Surface sizing agents (non-starch based)
• Wet-strength resins used as paper additives

Common Misclassification

A frequent misclassification involves HS code 350510, which covers modified starches and other amylaceous substances. Many sizing agents are starch-based; however, the 380992 description explicitly excludes products with a basis of amylaceous substances. If the sizing agent is primarily starch, it must go to 3505. Another confusion arises with 390690 (acrylic polymers) if the agent is a pure polymer rather than a prepared finishing agent. Always check if the product is a "preparation" or a raw chemical.

FAQ

What is the HS code for Paper sizing agent?

The HS code for chemical sizing agents used in the paper industry (excluding starch-based ones) is 380992.

Are starch-based sizing agents included in 380992?

No, starch-based (amylaceous) sizing agents are excluded from this code and are typically classified under heading 3505.
