The US formaldehyde regulations entitled TSCA Title VI will also end a transition period for relevant laminated products from 22 March 2024. From this date, these will be categorised as hardwood plywood and must meet the requirements accordingly. Specifically, this means that products in which, according to the definition, a wood veneer or wood-like grass veneer (e.g. bamboo) with a maximum thickness of 6.4 mm is applied to a wood-based substrate with a formaldehyde-containing adhesive (e.g. UF, MUF) are considered hardwood plywood. Manufacturers of these products must carry out TSCA Title VI certification, which includes auditing, regular testing and documentation. Exceptions continue to exist for products where the “veneers” are bonded with a formaldehyde-free or phenol-formaldehyde resin.
