| `weight` | Product weight |
| `weightMeasureUnit` | Unit of measure (kilograms, grams, milligrams, pounds, ounces) |
| `weightIsPrimaryData` | This field must be set to `true` in order to generate a score |
| `frenchLabelFabricCountry` | Geographical Location of *Textile Formation*. Include both the `code` and the `name` of the location: see [recipe](/recipes/french-eco-score-update) |
