Softwood Veneer and Plywood Price Trends: BLS PPI Data for Sheathing and Formwork Bids
Framing subcontractors, concrete formwork contractors, and commercial estimators rely heavily on structural wood panels for roof decking, wall sheathing, subflooring, and concrete forms. Because panel pricing can swing sharply over multi-month construction schedules, pricing bids accurately requires watching objective federal price tracking. This quick-reference explainer details producer price movements, baseline index values, and risk management strategies for contractors purchasing structural wood products.
Current Softwood Veneer and Plywood Price Baseline
According to the U.S. Bureau of Labor Statistics PPI series WPU0831, which monitors softwood veneer and plywood commodity prices on an index base period of 1982 = 100, panel material costs climbed steadily through the third quarter of 2026. The latest available monthly index value reached 342.2 in September 2026 (raw value 342.233). That represents a month-over-month increase of 2.7% compared to the August 2026 level of 333.1.
On an annual basis, structural panels have posted significant price expansion. One year earlier, in September 2025, the index stood at 295.4 (raw value 295.402). Comparing September 2025 to September 2026 shows an increase of 15.9%. Estimators pricing multi-story framing or heavy formwork packages must recognize that unadjusted panel budgets from late 2025 will fall short of current wholesale supply reality.
Multi-Year Trends and Post-Pandemic Context
Looking at longer cycles illustrates the degree of volatility inherent in softwood panel commodities. Two years earlier, in September 2024, the index was recorded at 307.0 (raw value 307.010), meaning the latest index sits 11.5% higher. Five years earlier, in September 2021, the index registered 301.8 (raw value 301.760), representing a 13.4% change to the latest figure.
When evaluated against pre-pandemic pricing, panel costs remain substantially elevated. In January 2020, the index was 205.5 (raw value 205.500), which also marked the lowest monthly value across the entire data window from January 2019 to September 2026. From January 2020 to September 2026, softwood veneer and plywood prices increased by 66.5%.
Despite this cumulative growth, current levels sit far below historic spikes. The highest monthly value recorded between January 2019 and September 2026 occurred in June 2021 at 702.5 (raw value 702.500). The latest September 2026 value is 51.3% below that historical peak.
Key BLS PPI Reference Benchmarks
The following table outlines key historical reference points from the federal dataset to assist estimators in establishing contractual baselines and auditing bid allowances.
| Reference Period | Index Value | Percent Change to September 2026 |
|---|---|---|
| September 2026 (Latest) | 342.2 | 0.0% |
| September 2025 (1 Year Earlier) | 295.4 | +15.9% |
| September 2024 (2 Years Earlier) | 307.0 | +11.5% |
| September 2021 (5 Years Earlier) | 301.8 | +13.4% |
| January 2020 (Pre-Pandemic Low) | 205.5 | +66.5% |
| June 2021 (Series Window High) | 702.5 | -51.3% |
Thirteen-Month Progression and Annual Averages
Examining the 13-month run from late 2025 into late 2026 reveals a consistent upward drift after a brief dip in late autumn. Monthly index values progressed as follows:
- September 2025: 295.4
- October 2025: 287.7
- November 2025: 291.1
- December 2025: 291.2
- January 2026: 294.2
- February 2026: 295.4
- March 2026: 301.5
- April 2026: 313.8
- May 2026: 322.0
- June 2026: 328.8
- July 2026: 330.2
- August 2026: 333.1
- September 2026: 342.2
Annual averages calculated from monthly figures reflect this longer trend. The annual average was 222.8 in 2019, rising to 270.6 in 2020, 449.6 in 2021, and 429.5 in 2022. It moderated to 323.9 in 2023, 316.2 in 2024, and 301.0 in 2025. For 2026, the average across January through September stands at 317.9.
Bidding Guidelines for Sheathing and Formwork Takeoffs
When compiling estimates for plywood-heavy scopes such as shear walls, temporary barricades, structural floor decking, and poured-in-place concrete forms, trade contractors must account for market shifts:
- Track Four-Month Revision Windows: Figures in the BLS softwood veneer and plywood commodity data are not seasonally adjusted, and recent monthly values remain preliminary and subject to revision for four months after initial publication. Ensure reconciliation calculations account for these published adjustments.
- Protect Extended Proposal Validity: With prices climbing from 294.2 in January 2026 to 342.2 in September 2026, holding fixed numbers across long procurement cycles introduces material exposure. Estimators should use targeted bid exclusions and clarifications to limit proposal holding windows.
- Establish Index-Linked Baselines: Where owners or general contractors require prolonged price guarantees, integrate formal price escalation clauses referencing series WPU0831 to manage price swings transparently.
