Defining HPD Scope

Defining HPD Scope

The first step for manufacturers to start creating Health Product Declarations is to define the reporting scope of the HPD. The HPD Scope is defined by two main parameters: the Content Inventory Display Method and the Reporting Threshold. 

Inventory display method

The Health Product Declaration (HPD) offers two overall ways to organize and display the content inventory: Basic and Nested. The Nested inventory is preferred by HPD users because it provides more granular data on a product, and it is the method manufacturers must use when importing suppliers’ data from the Supplier HPD Builder Extension tool.

Reporting Threshold

Thresholds — such as 100 ppm or 1,000 ppm— establish reporting requirements for substances on the HPD. 

There are two possible approaches the manufacturer can take when creating Nested Inventory HPDs:

  • Nested Materials Inventory with Material-level threshold: Thresholds are established for each listed material. Substances within each material are reported if they are above the established threshold for the material.
  • Nested Materials Inventory with Product-level threshold: A single threshold is established for the entire product. Substances within each material are reported if they are above the product threshold.
A material-level threshold means that the manufacturer must report all ingredients above that concentration in each material within the overall product. Choosing a product-level threshold means that the manufacturer must report all ingredients above that concentration in the entire product.

As an example, if a 1,000 ppm material thresholds is selected, manufacturers must report all ingredients present in the final product that weight at least 0.1% of the material total weight. 

Unless the manufacturer specifies the opposite, all data requests in the Supplier HPD Builder Extension are completed on a material level threshold.
