Bill of materials

A bill of materials (BOM) is the structured list of components, parts, and assemblies required to build a finished product, along with their unit costs and supplier sources. In humanoid manufacturing, BOM cost is the single most-cited metric for cost-down trajectory and unit-economics framing.

The distinction matters because BOM-cost claims routinely conflate marginal-unit cost with fully-loaded production cost. Figure's reported "BOM cost" target for Figure 03 is the component-cost-at-scale assumption — it excludes assembly labor, rework cost from first-pass yield gaps, supplier minimums, freight, and amortized tooling. The published BOM number is what the company is targeting at long-run volume; the actual current production cost is meaningfully higher. Below 80% first-pass yield, published BOM doesn't capture the rework that happens before each unit ships.
