Lumber Slides as Washington Weighs Wider Wood Tariff Scope

Wood buyers have a date to put in the calendar. Under the Section 232 proclamation signed on 29 September 2025, the Secretary of Commerce owes the President a report by 1 October 2026 on imports of hardwood timber and lumber, and on whether additional duties on hardwoods and their derivative products are warranted. That is six weeks out. Anyone quoting Q4 and Q1 arrivals into the United States is pricing against an open scope question.

The measure as it stands is narrower than the headlines suggest. Section 232 applies a 10% ad valorem tariff to softwood timber and lumber, and 25% to kitchen cabinets, vanities and upholstered furniture, per the White House proclamation as summarised by law firm Troutman Pepper Locke. Scheduled increases on the furniture and cabinet lines, to 30% and 50%, were pushed back a year and now take effect on 1 January 2027. Covered products from the UK are capped at 10%, and from the EU and Japan at 15%.

Price snapshot

North American lumber softened through the first half of August. Madison's Lumber Prices Index came in at US$536 per thousand board feet for the week ending 14 August, down 4%, or $22, from $558 the week before. Futures told a similar story. Lumber traded at $568 per thousand board feet on 14 August, roughly 9.8% below where it sat a month earlier and about 6.8% under the year-ago level, according to Trading Economics, which points to tariff uncertainty as a drag on demand.

We would not read a single 4% week as a turn in the market. Thin cash trade exaggerates weekly moves, and one print tells you about last week's order flow rather than where Q4 settles. The more useful signal for panel buyers is direction of travel. Softwood input costs are easing at the same time that policy risk on the same products is climbing.

Freight splits east and west

Container rates are moving in opposite directions depending on which way the box is pointed. Drewry's World Container Index rose 1% to $4,339 per 40ft container in the week to 13 August. Transpacific did the lifting. Shanghai to New York jumped 10% to $8,706 and Shanghai to Los Angeles gained 6% to $6,244. Asia to Europe went the other way, with Shanghai to Genoa down 8% to $5,080 and Shanghai to Rotterdam off 5% to $4,425.

Capacity management explains much of the split. Drewry counted 10 blanked sailings in each of the past two weeks on the Transpacific with seven more scheduled, against three blanks on Asia to Europe. Several carriers have filed Panama Canal surcharges on Asia to US East Coast and Asia to Gulf lanes effective September. Asia to Mediterranean FAK rates of $6,700 to $7,100 were announced from 15 August, though Drewry questions whether soft demand will hold them. Low water on the Rhine and port congestion in Asia after typhoon Dolphin are adding to schedule risk.

Translated into landed cost, a European buyer sourcing film-faced plywood from Southeast Asia has ocean freight working in their favour this month. A US buyer on the same product does not.

Demand stays uneven

US residential construction is still splitting by housing type. June starts came in at a seasonally adjusted annual rate of 1,427,000, 19% above May, but the gain was multifamily, which surged 76.3% to 513,000. Single-family fell 0.2% to 895,000, a third straight monthly decline. Permits eased 3% from May to 1,367,000 and sat 2.3% below June 2025, according to the US Census Bureau. That matters for panel demand because detached housing drives most structural sheathing volume, while multifamily leans harder on formwork and cast concrete. July figures land this week.

Two policy calendars to watch

The first is the 1 October Commerce report, which could recommend extending Section 232 duties to hardwood timber and lumber and to derivative products beyond the furniture lines already covered. Nothing has been proposed yet, and a report is not a tariff. Importers who filed the wood 232 action away as settled back in October 2025 still have reason to re-read their Q1 contracts.

The second is EUDR. The Council's targeted revision moved application to 30 December 2026 for large and medium operators, with small and micro operators following on 30 June 2027, and the Commission published a simplification package on 4 May 2026. European buyers who slowed their due-diligence work during the delay now have about four months.

Keep the scope straight while you plan. The Section 232 measures name softwood timber and lumber plus specific furniture and cabinet categories, not concrete formwork panels. The US antidumping and countervailing duty orders finalised in July cover hardwood and decorative plywood, which is a separate product category from the film-faced formwork panels used on construction sites. Buyers who conflate the two end up provisioning duty against the wrong line item.

Outlook

Cheaper lumber and dearer transpacific freight pull US landed cost in opposite directions, and neither looks likely to resolve before the Commerce report lands. Europe gets the better end of the freight trade this quarter, and the EUDR date gives buyers there a documentation task rather than a price one. Our mid-August brief flagged provenance paperwork as part of the price in Europe. The same logic now applies to tariff classification in the United States. Buyers planning Q1 arrivals should be asking suppliers for HS codes and origin documentation before 1 October, not after.
