| name | string | The name of the material | Steel |
| sku | string | The stock keeping unit | ST123 |
| unit | Unit | The unit of measure | kg |
| weight | Amount | The user-declared weight of the material | { quantity: 100, unit: "kg" } |
| packagingWeight | Amount | The user-declared weight of the material’s packaging | { quantity: 10, unit: "kg" } |
| modeledWeight | Amount | Read-only. Server-computed sum of the model’s A1–A3 product material input weights (Material group “Product”; excludes packaging and ancillary) | { quantity: 100, unit: "kg" } |
| modeledPackagingWeight | Amount | Read-only. Server-computed sum of the model’s A1–A3 packaging input weights (Material group “Packaging”); compare against the declared packagingWeight | { quantity: 12.5, unit: "kg" } |
| modeledTotalWeight | Amount | Read-only. Gross modeled weight: modeledWeight + modeledPackagingWeight, derived at read time (a missing addend contributes nothing); present when at least one of the two is present | { quantity: 112.5, unit: "kg" } |
| recycledPercent | number | The user-declared recycled content of the material as a percentage (0–100). A 0 is a declared zero; absent when undeclared | 30 |
| modeledRecycledPercent | number | Read-only. Server-computed weight-weighted average of the contributing inputs’ recycled content (0–100); compare against the declared recycledPercent | 27.5 |
