Sourcing MDF and fibreboard from China
Fibreboard of wood from China, including raw and faced MDF, HDF, laminate flooring boards and softboard, pays 6% UK duty, with no anti-dumping duty. Panels used in construction need a declaration of performance with UKCA or CE marking, including the formaldehyde class, and fibreboard is within the UK Timber Regulations. Cambridge China Bridge sources MDF and fibreboard.

A flat 6%
Read from the UK Trade Tariff on 25 September 2026, medium density fibreboard in every thickness band, high density fibreboard, laminate floor coverings on HDF and other fibreboard of heading 4411, raw or mechanically worked or surface covered, carried 6% duty on goods from China, with no anti-dumping measure.
Particleboard and OSB are in heading 4410 and plywood in 4412, and furniture made from MDF is classified as furniture; confirm the commodity code from the density, thickness and surface.

| MDF 5 to 9 mm, raw board | 4411 13 10 00 | 6% | None |
| MDF over 9 mm, raw board | 4411 14 10 00 | 6% | None |
| Laminate floor coverings on HDF over 9 mm | 4411 14 91 00 | 6% | None |
| Other HDF over 9 mm, worked or faced | 4411 14 93 00 | 6% | None |
| MDF over 9 mm, 0.5 to 0.8 g/cm3, worked or faced | 4411 14 95 00 | 6% | None |
| Other fibreboard over 0.8 g/cm3, worked or faced | 4411 92 90 00 | 6% | None |
Construction panels and timber legality
Wood-based panels used in construction are covered by the harmonised standard EN 13986, so under the Construction Products Regulation as it applies in Great Britain they need a declaration of performance and UKCA or CE marking, which states the formaldehyde class, usually E1, and the reaction to fire. The product specification for fibreboards, including MDF, is the EN 622 series, and laminate flooring is specified to EN 13329.
Fibreboard is within the UK Timber Regulations 2013, so the business placing it on the GB market must know the species and country of harvest and carry out due diligence on the risk of illegal timber. Ask the mill for the fibre sources and any chain of custody certificate, such as FSC or PEFC.
Worked duty example
For a made-up shipment of one container of 18 mm HDF panels under 4411 14 93 00, add the £2,600 of freight and insurance to the £14,000 free-on-board price and customs sees £16,600. At 6%, duty on these fibreboard panels is £996; import VAT of £3,519.20 is 20% of the value with duty added. Together that is £4,515.20, but a VAT-registered importer usually gets the VAT back. The duty and VAT guide walks through the calculation.
Inspection checklist
Physical properties: board checked against BS EN 622-5 for its type, with density by BS EN 323, internal bond by BS EN 319, thickness swelling after 24 hours by BS EN 317, bending strength by BS EN 310 and moisture content by BS EN 322 tested on boards from the shipped batch.
Formaldehyde and marking: emission tested by the chamber method of BS EN 717-1 or the perforator method against the class declared, E1 under Annex B of BS EN 13986 as a minimum, and construction panels checked for the declaration of performance and UKCA or CE marking under BS EN 13986.
Dimensions and packing: thickness measured at several points on sample sheets, length, width and squareness checked, surfaces and edges inspected for blows, spots and chipping, laminate flooring checked against BS EN 13329 for its abrasion class, and bundles wrapped and raised off the container floor.

What goes wrong
MDF fails on density, moisture and emissions. Boards with a soft core crumble at screw holes and edges, thickness varies across the sheet so it will not machine to size, and panels that leave the press too dry or too wet warp in the UK climate. A board sold as E1 that was made with cheaper resin can emit more formaldehyde than declared, and moisture-resistant grades are sometimes plain board with a green dye.
Ask for test reports on density profile, internal bond, thickness swelling and formaldehyde emission for the actual production batch, measure thickness across sample sheets, check moisture content on arrival, and at inspection check edges, surface defects, stacking on flat pallets and edge protection. Store sheets flat and covered when they land.

Does MDF need UKCA marking?
Panels used in construction do, under EN 13986, with a declaration of performance that states the formaldehyde class.
Is MDF covered by the UK Timber Regulations?
Yes. Fibreboard is in scope, so the importer must carry out due diligence on the timber's origin.
Where do particleboard and plywood go?
Particleboard and OSB are in heading 4410 and plywood in 4412.
