The Trade Brief - 17 August 2026

Today's edition covers the Canada 50% tariff on construction materials taking effect at 12:01 a.m. ET tomorrow, Balfour Beatty's first-half numbers in detail, a widening backlog gap between large and small U.S. contractors, copper and electrical equipment escalation driven by data center demand, and new domestic rebar capacity that may temper steel price growth later this year.

Canada-U.S. tariff on building materials takes effect 19 August - no deal confirmed as of the weekend. The 50% Section 338 duty signed by President Trump on 20 July 2026 covers lumber, plywood, doors, cement, and a broad range of other construction inputs imported from Canada, and applies even to goods that would otherwise qualify for duty-free treatment under USMCA^[1]. As of 13 August, a Canadian government source said both sides wanted an agreement before the deadline, and Trade Minister Dominic LeBlanc met U.S. Trade Representative Jamieson Greer for a fourth time in three weeks. No framework was publicly confirmed before the weekend. Contractors who have not pre-positioned Canadian-origin materials face a 50% cost increase on those lines starting tomorrow morning; project teams with open purchase orders should confirm country-of-origin status and whether any FTZ admissions need to convert to privileged foreign status before consumption entry.

Balfour Beatty's U.S. construction division swung from an £11 million loss to a £22 million profit in the first half of 2026, with U.S. revenue up 19% to £2.48 billion. The group raised its full-year guidance and reported average net cash of £1.62 billion, up from £1.21 billion for the full 2025 financial year. The £22.9 billion order book provides forward visibility, with U.S. buildings and UK power transmission cited as the primary growth drivers. The U.S. civils division still posted losses, but at a much-reduced level compared with the prior period. For U.S. subcontractors and suppliers working in the Balfour Beatty supply chain, the improved cash position and raised guidance signal continued volume through the second half^[2].

Data center construction is masking a widening backlog gap between large and small U.S. contractors. Firms with more than $100 million in annual revenue reported 12.1 months of backlog in July 2026, compared with seven months for contractors with less than $30 million in revenue^[2]. The concentration of mega-project work - data centers, power infrastructure, advanced manufacturing - in the hands of large builders means smaller specialty contractors and regional firms are not sharing equally in the current boom. Specifiers and developers sourcing bids from smaller firms should factor in the tighter pipeline when assessing schedule risk.

Copper and electrical equipment costs are the sharpest escalation risk on U.S. jobsites this summer, driven by data center demand. Copper mill shapes are up approximately 27% year-over-year and approximately 103% since January 2020, with data center construction straining transformer and switchgear lead times across the country. Electrical scopes are the most vulnerable to both cost escalation and schedule slippage on active projects. Owners and GCs who have not locked in transformer and switchgear pricing and delivery slots for projects starting in late 2026 or early 2027 face meaningful exposure; the supply constraint is not expected to ease until new manufacturing capacity comes online.

U.S. rebar supply is set to grow as Nucor, CMC, and Hybar add more than 1.5 million short tons of new capacity in 2026, which should temper structural steel price growth despite existing tariff pressure. Steel mill products are up approximately 86% since January 2020, but the domestic capacity additions are expected to moderate further price increases on rebar-heavy civil and infrastructure work. Contractors bidding long-duration horizontal projects - roads, bridges, water infrastructure - may find it worthwhile to delay locking in rebar pricing until the new capacity is reflected in spot markets, while continuing to hedge on fabricated structural steel, which remains on a different supply trajectory.
