# Optional Fields

> Optional durability fields that refine the French Eco-Score calculation for a product.

When [creating](/api-reference/pic/products/create) or [updating](/api-reference/pic/products/update) a product, you can include the `frenchLabelOptionalFields` object to provide additional durability and business context. These fields are not required to generate a score, but supplying them can improve its accuracy.
