-we can also force amount ecotaxe on account move line by classification.
+       .. code-block:: python
+
+          result = quantity and product.fixed_ecotax * quantity or 0.0
+
+     - For the weight-based ecotax:
+
+       .. code-block:: python
+
+          result = quantity and product.weight_based_ecotax * quantity or 0.0
+
