US Adjusts Tariffs on Canadian Plywood, MDF, Wood Mouldings
The White House announced changes effective October 30, removing duties on certain packaging and plywood while extending them to specific fiberboard and wood mouldings.

New US Tariff Regime for Canadian Wood
The White House has announced a revision of tariffs on certain Canadian wood and paper products, with the updated measures taking effect on October 30. These changes, disclosed on October 23, modify duties previously introduced on July 20 and amended on September 8 this year.
The adjustments fall under Section 338 of the Tariff Act of 1930, impacting a range of building materials and packaging goods traded between the two North American nations.
Products Exempted from Duties
Under the revised policy, several product categories will no longer incur import duties. These include certain thin hardwood plywood, coated paperboard, corrugated cartons and boxes, and various paper sacks and bags.
Additionally, moulded pulp articles, some plastic packaging components, refrigeration and packaging machinery, and produce-sorting equipment are now exempt from tariffs. This removal of duties aims to streamline trade for specific goods previously affected by the tariff regime.
Extended Tariffs on Other Materials
Conversely, the updated measures extend tariffs to other wood and paper products. Among these are medium-density fiberboard (MDF) no more than 5mm thick, high-density fiberboard, and wooden packing boxes. Duties will also apply to wood mouldings, engineered flooring, and bamboo joinery.
Further items now subject to tariffs include vinyl flooring, carpets, certain valves, and paints, broadening the scope of affected materials.
Implications for Asian Building Material Sourcing
For procurement teams and specifiers in Asia, these tariff adjustments in North America could influence global supply dynamics for specific building materials. The imposition of new duties on Canadian medium-density fiberboard (MDF), engineered flooring, and bamboo joinery may prompt US buyers to seek alternative sources.
This shift could open opportunities for Asian manufacturers of these products, particularly those in Vietnam, Malaysia, and Indonesia, to increase their exports to the US market. Companies should assess their supply chains for potential shifts in demand and pricing for these categories in the coming months.
