Where does sawnwood come from?

In 2024 United States produced 75.5 million m3 of sawnwood, 17% of the world's 444.9 million m3 (FAOSTAT forestry). China followed with 14%, then Russia (8.4%), Canada (7.9%) and India (5.4%). The top five together account for 52%, 227 reporting units recorded production, and 32% came from outside the top ten.

Sawnwood means wood sawn lengthwise to a thickness greater than six millimetres: boards, planks, beams and scantlings. It is overwhelmingly a softwood product. Spruce, pine and fir from the boreal and temperate belt account for most of the volume because they grow straight, mill easily, dry predictably and are strong enough for construction framing. Tropical hardwood sawnwood is a small share of volume and a much larger share of value per cubic meter, sold into joinery, flooring, boatbuilding and furniture rather than structural use.

The map follows the softwood forest and the housing market together. The United States and Canada mill for North American construction; Sweden, Finland, Germany and Austria mill for European construction and export; Russia mills for China and, until sanctions complicated it, for Europe; China mills imported logs for its own market; and Brazil and Chile mill fast-grown plantation pine for export. Where a country appears high in production but low in exports, it is milling for itself.

World output changed -1% over the ten years to 2024 and -0% on the previous year. Volume has been broadly flat for a decade while the value of the trade has swung enormously, which tells you that this is a mature industry whose fortunes turn on construction cycles and prices rather than on growth in the quantity of wood cut.

Canada was the largest exporter of sawnwood (HS 4407) in 2024 with 17% of world export value, ahead of Sweden (9.8%), on world trade of $38 billion (CEPII BACI). United States was the largest importer with 20%.

A far larger share of sawnwood is traded than of logs, because the saw has already removed the waste and the value density is higher. The two dominant flows are Canadian softwood lumber moving south into United States construction, which has been the subject of a decades-long trade dispute and repeated duties, and Nordic and Russian spruce moving into Europe, north Africa and Asia. Both are structural rather than opportunistic: they exist because forest and market are in different countries and no amount of price movement changes that.

The tropical trade runs the other way in character. It is small in volume, high in value, concentrated in a few species, and increasingly shaped by which suppliers can document legality for European and American buyers. Some producers that once exported logs now export sawnwood instead, not because milling became more attractive but because exporting logs was banned.

The two World Bank series here are tropical hardwood, and the page should not pretend otherwise. Cameroon, sapele, FOB Douala was $648.7/m³ in August 2026, up 1% from a year earlier (World Bank Pink Sheet). The nominal high was $1,088/m³ in June 2008 and the real high $1,597/m³ in February 2008. Those are sapele from Cameroon and dark red meranti from Malaysia, quoted free on board.

The softwood construction lumber that makes up most of world sawnwood prices somewhere else entirely. In North America it is assessed by private price reporting services as a delivered price for a specified dimension and grade, most famously two-by-four western spruce-pine-fir, and hedged on the CME lumber contract, which covers 27,500 board feet quoted in dollars per thousand board feet. In Europe, sawnwood is largely sold on quarterly or annual contracts negotiated between mills and merchants rather than against a public index. Neither of those markets tracks the tropical quotations above, and a reader looking for the price of framing lumber should go to the CME contract, not to this series.

Physical sawnwood is priced by species, dimension, grade, moisture content and treatment. Kiln-dried structural lumber graded to a published standard sells at a substantial premium to green rough-sawn material, and a board's grade is determined by knots, slope of grain and defects that a machine or a grader assesses piece by piece. The board foot, still used in North America, is a nominal measure that does not correspond to the finished dimensions of the wood, which is why a two-by-four is not two inches by four inches.

Framing lumber demand tracks residential construction almost one for one, so mortgage rates and housebuilding permits are the leading indicator for sawnwood prices. Because mills cannot adjust output quickly and lumber cannot be stored cheaply for long, small changes in construction activity produce large changes in price, which is why lumber is among the most volatile of all industrial commodities.

Logs are the largest input cost and their availability is set by planting decisions made decades earlier, by harvest permits and by export bans in supplying countries. When log costs rise or a supply route closes, as it did for Russian logs in 2022, mills either pay more or run below capacity, and both outcomes lift lumber prices.

The long-running dispute over Canadian softwood lumber entering the United States has repeatedly produced antidumping and countervailing duties that add directly to the delivered cost of a large share of American supply. Duty rate changes move the North American price without any change in how much wood exists.

Milling capacity is added slowly and closed permanently, so the industry oscillates between shortage and glut. During a shortage, mills earn extreme margins and add shifts; during a glut, high-cost mills close and their local log supply is stranded. Capacity, not forest area, is usually the binding constraint on how much sawnwood exists in a given year.

Large-scale forest damage forces owners to cut and sell timber before it degrades, flooding mills with cheap logs and depressing lumber prices for a few years, then leaving a supply gap that lasts far longer. Mountain pine beetle in British Columbia and spruce beetle in central Europe both ran this cycle.

Sawnwood moves by bulk vessel, container and rail, and it competes for space with higher-value cargo. When container rates spike or railcars are short, delivered prices in importing markets rise even when mill prices do not, and the trade shortens toward nearby suppliers.

Steel and concrete framing compete with wood in mid-rise construction, and engineered products such as cross-laminated timber and laminated veneer lumber compete with solid sawn beams. Relative prices and building codes decide the split, and code changes permitting taller timber buildings have been a slow but real source of new demand.

A log arriving at a sawmill is scanned to find the cutting pattern that yields the most valuable set of boards, then debarked and broken down by a headrig saw. Modern mills use optimising scanners and curve-sawing to follow the natural sweep of a log, which recovers noticeably more wood than sawing straight through. Recovery, the share of log volume that leaves as boards, runs around half for good softwood logs, and the rest becomes chips, sawdust and bark, all of which are sold rather than discarded.

Green boards are edged and trimmed, then dried, either air-dried over months or kiln-dried over days. Drying is what makes lumber dimensionally stable and it is where a great deal of the energy cost sits; mills typically burn their own bark and sawdust to fire the kilns. Dried boards are planed to final dimension, graded, and often stress-tested, then bundled and wrapped.

Grading is the step that turns a commodity into a product. Structural lumber is assigned a grade based on knots, grain slope, wane and other defects, either visually or by machine stress rating, and the grade determines the design values an engineer may use. A board that fails structural grading is sold for lower-value uses. Treatment, pressure-impregnating preservative for ground contact or applying fire retardant, adds another price step.

Volumes on this page are cubic meters of sawnwood, not of the logs consumed. Because recovery is roughly half, producing the world's 444.9 million m3 of sawnwood consumed a substantially larger volume of logs, which is why the sawnwood and roundwood tables are not directly comparable.

Construction takes most of it. Softwood sawnwood becomes wall studs, floor joists, roof trusses, formwork for concrete and the frames of the great majority of houses in North America, the Nordic countries and Japan. Where building traditions favor masonry, as in much of southern Europe, wood is used more for roofs, floors and joinery than for structure, which is why consumption per person varies so widely between countries at similar income levels.

Beyond framing, sawnwood is the input to a long list of secondary industries: furniture, flooring, doors and windows, packaging and pallets, fencing and decking, and the glue-laminated and cross-laminated products that let architects build tall buildings in timber. Pallets alone absorb a large volume of low-grade lumber and are the reason a shortage in construction lumber quickly becomes a shortage in shipping supplies.

Tropical hardwood sawnwood serves a different set of uses where appearance, durability or dimensional stability justify the price: boatbuilding, exterior joinery, high-end flooring and furniture, and musical instruments. Substitution away from these species, driven partly by cost and partly by legality concerns, has been steady for decades.

Sawmilling is a scale business built next to its log supply, and that creates a tight mutual dependence: a mill needs a haulage radius full of standing timber, and a forest needs a mill within reach to have any value. When one closes, the other loses. Regions therefore experience wood supply shocks as regional economic events rather than as price signals.

The seaborne chain is unremarkable but capacity-constrained at the edges. Bulk and break-bulk vessels move packaged lumber from Nordic, Russian, Chilean and Brazilian ports; containers carry higher-value and tropical material; rail moves Canadian lumber into the United States. The bottlenecks appear at port storage and at rail capacity rather than at sea, and lumber loses out to higher-value cargo when space is scarce.

The genuine single points of failure are policy and pest. A duty decision can reprice a third of a national market overnight, and an insect interception can close a lane. Kiln drying and heat treatment are required by phytosanitary rules for most international shipments precisely because the alternative is exporting forest pests along with the wood, and the treatment certificate is as necessary as the bill of lading.

Finally, the industry's fiber base is shifting. Plantation softwood in the southern hemisphere and the southern United States is displacing boreal natural forest at the margin, and mills built for large old-growth logs do not run well on small plantation stems. Retooling for smaller diameters is a slow, capital-hungry adjustment that constrains how quickly supply can respond to a price spike.
