HS Code for Densified wood

Densified wood is classified under HS code 4413.00. This classification is applied to wood that has undergone a specific transformation to increase its density and hardness. This is achieved through either chemical or mechanical treatment, or a combination of both. In the chemical process, the wood is typically impregnated with synthetic resins or other chemicals that fill the cellular structure. In the mechanical process, the wood is subjected to intense pressure and heat, which collapses the cell walls and compacts the fibers. The resulting material is significantly stronger and more resistant to moisture than natural timber. HS code 4413.00 is a specific heading for this modified wood in basic forms like blocks, plates, strips, or profile shapes, provided they have not been further manufactured into finished consumer goods.

Products Included

• Resin-impregnated densified wood blocks
• Compressed wood plates for industrial use
• Laminated densified wood strips
• Hardened wood profiles for tool handles
• Chemically densified timber for electrical insulation

Common Misclassification

Densified wood is often confused with plywood or laminated wood under HS code 4412. While both involve layers, 4412 is for standard veneers, whereas 4413 requires the specific densification process (impregnation or extreme compression). It is also sometimes misclassified under 4407 (sawn wood) if the customs officer does not recognize the chemical or mechanical modification of the wood's density.

FAQ

What is the HS code for densified wood?

The correct HS code for densified wood in blocks, plates, strips, or profile shapes is 4413.00.

Is densified wood the same as treated lumber?

No, treated lumber (usually 4403 or 4407) is treated for preservation against rot or insects, whereas densified wood (4413) is physically or chemically altered to change its density and hardness.
