HS Code for Thick MDF

Thick Medium Density Fibreboard (MDF) is classified under HS code 4411.14. This classification falls under Chapter 44, which covers wood and articles of wood. Heading 4411 specifically addresses fibreboard of wood or other ligneous materials, whether or not bonded with resins or other organic substances. Within this heading, the 4411.1x series is dedicated to MDF. The subheadings are determined by the thickness of the board. Subheading 4411.14 is reserved for MDF with a thickness exceeding 9 mm. The classification process involves first identifying the product as MDF, which is produced using a "dry process" where the wood fibers are dried before being felted and pressed with synthetic resins. This distinguishes it from "wet process" hardboard. Once identified as MDF, the thickness is the primary determinant for the 6-digit code. Thick MDF is widely used in the furniture industry for tabletops, cabinet doors, and structural components due to its stability and ease of machining. The measurement of thickness must be precise, as boards exactly 9 mm or thinner fall into different subheadings (4411.12 or 4411.13). The classification remains 4411.14 even if the board is sanded, laminated, or veneered, provided it retains the character of MDF and is not further worked into a specific article of furniture.

Common Misclassification

Thick MDF is frequently misclassified under 4411.13, which is for MDF with a thickness exceeding 5 mm but not exceeding 9 mm. Importers must ensure that the actual physical measurement exceeds the 9 mm threshold. Another common error is 4412 (plywood), but MDF is a fibreboard made from individual fibers, whereas plywood is made from thin sheets of wood veneer. Finally, if the MDF is cut to a specific shape for a piece of furniture, it might be misclassified as 9403, though it should remain in 4411 unless it is clearly a finished part.

FAQ

What is the HS code for thick MDF?

The HS code for Medium Density Fibreboard (MDF) with a thickness exceeding 9 mm is 4411.14.

Does this code include laminated MDF?

Yes, MDF that is surface-covered (laminated, painted, or veneered) is still classified under 4411.14, provided it is thicker than 9 mm.
