To assess Full Material Disclosure with ranges, 3E Exchange will follow certain properties to determine the overall compliance of the product. For products with materials and substances that use ranges, 3E Exchange will add together the ranges completely additively using the lower bound numbers and the upper bound numbers, respectively.

In the image below, we have a very simple product bill of material. We can see the product has two substances that have the following ranges for weight data: 1) 50%-75% and 2) 0%-25%. 3E Exchange will perform the following actions: 50% + 0% and 75% + 25% and the final range will be calculated as 50%-100%. In this case, the resulting lower bound is 50% and the upper bound is 100%. We can see that the example below has Full Material Disclosure, as the Compliance determinations are completed. The product/material has Full Material Disclosure if the final upper bound is 100% or greater.

To assess Full Material Disclosure with ranges in products or materials with alternatives, 3E Exchange will follow certain properties to determine the overall compliance of the product. When calculating Full Material Disclosure with alternatives, 3E Exchange will take the minimum of the lower bound and the maximum of the upper bound.

If a product or material has two substances that are alternatives have the following ranges for weight data: 1) 50%-75% and 2) 0%-25%. 3E Exchange will find the lesser of 50% and 0% and the greater of 75% and 25% and create the resulting range of 0%-75%.
