Product classification
HS code for Thick MDF: 4411.14
Medium density fibreboard (MDF), of a thickness exceeding 9 mm.
Classification of thick MDF under HS 4411.14
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.

Codes often confused with 4411.14
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
