HS Code for Thin MDF

Thin MDF is classified under HS code 4411.12 because it falls within the category of medium density fibreboard (MDF) with a thickness not exceeding 5 mm. The Harmonized System organizes wood products in Chapter 44, where 4411 specifically addresses fibreboard of wood or other ligneous materials, whether or not bonded with resins or other organic substances. The sub-classification 4411.12 is determined by the density and the specific thickness threshold. MDF is distinguished from other fibreboards like hardboard or particle board by its manufacturing process, which involves dry-forming fibres with synthetic resin adhesives under heat and pressure. For a product to be classified here, it must meet the density requirements of MDF (typically between 0.5 g/cm³ and 0.8 g/cm³) and remain at or below the 5 mm thickness limit. This classification applies regardless of whether the board is sanded, surface-worked, or coated, provided the essential character remains that of MDF.

Products Included

• Standard thin MDF panels
• Lacquered or painted thin MDF
• Veneered thin MDF (where the core is MDF)
• High-density thin fibreboard meeting MDF specifications
• Thin MDF used for picture frame backings

Common Misclassification

Thin MDF is frequently confused with HS code 4411.13, which covers MDF with a thickness exceeding 5 mm but not exceeding 9 mm. It is also often misclassified under 4411.92, which refers to other fibreboards like hardboard that are manufactured using a wet process rather than the dry process used for MDF. Additionally, some importers mistakenly use 4410.11 for particle board, which is made from wood chips rather than wood fibres.

FAQ

What is the HS code for Thin MDF?

The HS code for Thin MDF with a thickness not exceeding 5 mm is 4411.12.

How is MDF distinguished from hardboard in the HS system?

MDF is generally produced via a dry process using resin, whereas hardboard (classified under 4411.92 or 4411.93) is typically produced via a wet process where the fibres are felted in water.
