U.S. Paper Packaging Producer Prices: 2026 BLS PPI Signals
JAN–JUL 2026 · PRELIMINARY
Validated U.S. Bureau of Labor Statistics Producer Price Index data show that U.S. paper-packaging price signals diverged in the January–July 2026 matched-period comparison. Folding Paperboard Box Manufacturing was down 4.01%, while the setup (rigid) paperboard-box product series was up 6.86%. The comparison uses the average of January–July 2026 against the same seven months of 2025; it is not a January-to-July change.
Corrugated and Solid Fiber Box Manufacturing was up 3.91%, Other Paperboard Container Manufacturing up 5.61%, Paper Bag and Coated and Treated Paper Manufacturing up 6.22%, and Paperboard Mills up 1.39%. These are producer-price index movements, not supplier quotations, price-per-box changes, raw-material costs, or landed-cost estimates. BLS PPI source.
PPI measures average movement in producer selling-price indexes for exact published series. It does not provide a representative box price, buyer invoice, supplier quote, margin, forecast, or cost breakdown.
Key findings

The dark vertical line is the zero axis. Bar direction and length show the matched-period index signal, not a change in unit box cost.
Paper-packaging producer prices did not move as one market
The six validated series span a range from −4.01% to +6.86% under one matched-period method. That spread is the central finding. A single claim that “paper packaging prices rose” would hide the negative folding-paperboard-box signal and flatten meaningful differences among industry and product classifications.
The result does not show that every producer in a positive series changed its selling prices by the displayed percentage, or that every buyer experienced the same direction. PPI is an aggregate index for the exact series. Package dimensions, board grade, structure, printing, finishing, order quantity, contract timing, and supplier mix remain outside the statistic.
Folding paperboard boxes moved in the opposite direction
The BLS PPI industry series for Folding Paperboard Box Manufacturing recorded a −4.01% matched-period metric. It was the only negative observation in this six-series comparison. That makes it analytically important: broad “paper packaging inflation” language would not describe all selected categories accurately.
The negative index signal does not establish supplier discounting, weaker demand, excess capacity, lower margins, or a reduction in what any buyer paid. Those explanations would require separate evidence. The supported statement is narrower: the average January–July 2026 index was 4.01% below the average for the same 2025 months in this exact BLS industry series.
Setup boxes, paper bags and other paperboard series rose more strongly
The setup (rigid) paperboard-box industry-product series showed the largest positive metric, +6.86%. Paper Bag and Coated and Treated Paper Manufacturing followed at +6.22%, and Other Paperboard Container Manufacturing at +5.61%. These categories are not interchangeable. The setup-box observation is a product subseries within other paperboard container manufacturing, while the other two observations are broader industry series.
The percentages should be described as PPI movements. They are not evidence that all rigid boxes, paper bags, or other containers cost buyers the displayed percentage more. They also do not isolate print, board, labor, energy, freight, or any other cause.
Corrugated was positive but below several other series
Corrugated and Solid Fiber Box Manufacturing recorded a +3.91% matched-period PPI signal. The direction was positive, but the magnitude was below the setup-box product, paper bag/coated-treated paper industry, and other paperboard container industry observations.
DN-01 separately reports a customs-value movement for a corrugated trade classification. The two evidence streams should not be combined to claim that imports, demand, or capacity caused the corrugated PPI result. Trade statistics describe recorded import activity under an HTS category; PPI describes producer-price index movement for a domestic industry series.
Upstream paperboard mills showed a different signal
Paperboard Mills recorded a +1.39% matched-period PPI signal, below each positive finished-packaging series in this comparison. It provides upstream producer-price context, but it is not a direct measure of paperboard input cost for a particular converter or package.
No pass-through calculation is supported. Finished-package indexes and the mill industry index have different series scopes and can reflect different product mixes. Subtracting one percentage from another would not reveal conversion cost, margin, material contribution, or a supplier’s expected quote.
PPI is not a supplier quote
BLS Producer Price Indexes measure average changes over time in selling prices received by domestic producers for their output. An index is suited to direction and matched-period comparison; it is not a currency price for a physical package.
A current packaging quotation depends on a controlled specification and commercial terms. Dimensions, tolerance, substrate, flute or caliper, print process and coverage, coating, lamination, finishing, inserts, closure, testing, tooling, plates, packing state, quantity, delivery schedule, freight, tariffs, and Incoterms can all affect transaction economics. PPI does not supply those inputs or replace comparable quotes.
Why classification matters
Five observations correspond to BLS industry series. The setup (rigid) paperboard-box observation is an industry-product subseries. The series are useful together as a transparent comparison set, but they are not statistically identical product universes. Exact titles and classification levels must remain visible so a commercial nickname does not silently broaden the evidence.
| Series / category | Jan–Jul 2026 matched-period signal |
|---|---|
| Setup (rigid) paperboard boxes | +6.86% |
| Paper Bag and Coated and Treated Paper Manufacturing | +6.22% |
| Other Paperboard Container Manufacturing | +5.61% |
| Corrugated and Solid Fiber Box Manufacturing | +3.91% |
| Paperboard Mills | +1.39% |
| Folding Paperboard Box Manufacturing | −4.01% |
What packaging buyers can take from the data
- Match the series to the category. Use the closest valid BLS scope rather than one broad paper-packaging assumption.
- Keep categories separate. Corrugated, folding, setup-box, other-paperboard and paper-bag industry signals moved differently.
- Use PPI as context. It can frame a quote discussion, but it cannot establish the correct project price.
- Separate transaction inputs. Review specification, quantity, tooling, freight, tariffs and commercial terms independently.
Methodology and sources
This Data Note uses six validated, not-seasonally-adjusted BLS Producer Price Index series. Corrugated and Solid Fiber Box Manufacturing, Folding Paperboard Box Manufacturing, Other Paperboard Container Manufacturing, Paper Bag and Coated and Treated Paper Manufacturing, and Paperboard Mills are industry series. Setup (rigid) paperboard boxes is an industry-product subseries under Other Paperboard Container Manufacturing.
For each series, the arithmetic compares the average of the seven monthly index observations from January through July 2026 with the average of January through July 2025: ((2026 matched-period average ÷ 2025 matched-period average) − 1) × 100. Display values are rounded to two decimal places. The method is a matched-period average-index comparison. It is not a January-to-July change, a July-only year-over-year result, an annual rate, or a forecast.
Index levels themselves are not compared because individual series can use different reference bases. Converting each observation to a matched-period percentage change supports a consistent directional comparison, but it does not make the underlying product universes identical. The chart therefore ranks calculated index signals rather than price levels.
Recent 2026 PPI observations are preliminary or revisable. The evidence cutoff is August 21, 2026, and no later BLS observation is introduced. PPI measures index movement at the producer level; it does not measure unit box prices, buyer costs, supplier quotations, material input costs, margins, or landed cost. The analysis makes no causal attribution.
