Building Paper and Board PPI in June 2026
Key stats
Building paper and board prices fell 2.8 percent in June 2026 and 2.7 percent over 12 months.
Contents
Key takeaways
- The June and 12-month movements come from a distinct BLS producer-price series.
- The index is a national benchmark, not a contractor quote or installed-cost factor.
- A project estimate still depends on product classification, basis weight, performance rating, package quantity, accessories, freight, and waste.
Key data table
Use this table as a review aid. The headline statistic is sourced directly; the interpretation rows explain how to apply it without treating a market benchmark as a project quote.

What the data can and cannot do
Public labor, spending, productivity, and price series provide a common baseline. They can reveal direction, scale, and unusual movement. They cannot identify the exact labor crew, subcontractor coverage, waste factor, access constraint, or escalation risk on a specific project.
A responsible estimate keeps the public benchmark separate from local bid history. Record the source date, geography, units, seasonal treatment, and any conversion before using the number in an estimate review.
How estimators should use it
- Use the series as a reasonableness and escalation signal for roofing underlayment and building-paper estimates.
- Keep the published period and seasonal treatment with the estimate note, then refresh current supplier or subcontractor evidence.
Add a source note beside every adjusted rate. If the benchmark and recent quotes disagree, do not average them automatically. Investigate geography, scope, timing, units, and market segment first.
Data sources and methodology
The primary statistic is transcribed from the source identified in the source notes below. The additional links are a consistent reader reference set for broader labor, construction volume, productivity, and regional context. They do not support or alter the headline figure and are not presented as article-specific evidence.
- BLS Table 2 reports the selected series and marks the June 2026 values preliminary.
- The first reported value is the unadjusted 12-month change; the final column is the seasonally adjusted May-to-June change.
Conservative convention: retain the published unit and date, avoid false precision, and treat national or sector data as a planning signal until local project evidence confirms it.
Frequently asked questions
Can this statistic set a project unit rate?
No. It can challenge or frame an assumption, but a project rate still needs current scope, geography, crew, productivity, supplier, and subcontractor evidence.
How often should the source be checked?
Check the primary release before a major estimate update and record the release or access date in the estimate notes.
Why are reader context sources included?
They give readers a consistent path to broader official construction and labor series. They are not evidence for the headline statistic and do not replace or alter its primary source.
Conclusion
Building paper and board prices fell 2.8 percent in June 2026 and 2.7 percent over 12 months. Use the figure as a documented benchmark, preserve the source date and units, and require project-specific evidence before changing a bid assumption.
