Nonferrous Mill Shapes: A Cost Scenario With an Explicit Pass-Through Assumption

Source identity correction: this page previously described aluminum mill shapes. The stored BLS series is WPU1025, Nonferrous Mill Shapes, covering the broad nonferrous mill-shapes commodity group. The historical readings and page address are preserved; the earlier narrower product interpretation was incorrect.

Nonferrous Mill Shapes stands at 399.03 index (1982=100) in the latest archived observation, Aug 2026, up about 23.3% from a year ago. These are index points with a 1982=100 base, not dollars per pound or per tonne.

The observation and the assumption are different inputs

The observed series is WPU1025, up about 23.3% from a year ago. Applying its percentage change to a component requires an additional assumption about which share of that component's price follows the index. This series does not establish pass-through for a vehicle panel, electrical winding, tube, extrusion or any other specific product. Use a matched transaction series or an agreed contract formula to justify that share.

Nonferrous Mill Shapes, Aug 2026: 399.03. WPU1025; broad producer price index, 1982=100.

An illustrative calculation

Assume a $100,000 budget, a 50% index-linked share and a hypothetical 10% increase in the selected benchmark. The modeled change is $100,000 × 50% × 10% = $5,000, making the scenario total $105,000. These are chosen example inputs, not measured pass-through or a forecast. Replace the assumptions with your own documented contract and pricing terms before using the result.

Check the scope of any comparison

Use this series as broad producer-price context. It does not isolate aluminum, copper, brass, an alloy, a finished component or your supplier's invoice. A movement in the aggregate cannot identify which metal moved or separate raw-material, energy, labor and fabrication contributions. For a product-specific decision, obtain the corresponding product series and supplier pricing on the same units and dates.
