HPD 2.2 Standard
HPD v2.2: The most advanced HPD Open Standard yet
The Health Product Declaration Collaborative (HPDC) released HPD Open Standard v2.2, including revisions to the standard’s instructions and format, on May 7, 2019. This release includes the publication of revisions to the standards instructions and format, which can be downloaded on this page.
HPD v2.2 was implemented in the HPD Builder, becoming the current “Effective” version of the HPD Open Standard, on May 18, 2020.
New in HPD v2.2: Supplier HPD and parts inventory
The signature features of HPD v2.2 are new tools for incorporating supply chain information more directly into the HPD reporting process.
- In a new innovation, HPD v2.2 distinguishes between two different forms of HPD: the Product HPD and the Supplier HPD. The Product HPD is the format that you have been familiar with if you have seen an HPD before. It reports on the contents of a complete product.
- The Supplier HPD contains some but not all of the data elements of a complete Product HPD. The Supplier HPD is a tool for ingredient suppliers to provide complete and accurate content inventory and associated health information data directly to product manufacturers for reporting in Product HPDs. As with the Product HPD, the Supplier HPD may provide hazard screening information while withholding proprietary substance identification, and be considered compliant with the HPD Open Standard if all other reporting requirements are met.
- HPD v2.2 also offers new view on all this data. The Part inventory enables the entry of information from suppliers using the Supplier HPD to display as a “Part” of the complete product described by the Product HPD. Thus the HPD facilitates integration of electronic data entry with existing supply chain tools, which utilize a Bill of Materials structure. The part inventory is an optional display that can be shown at the end of the existing Section 2 content inventory of the Product HPD (download the sample format to the right of this page and view Section 2b).
With these new HPD v2.2 capabilities the maker of the caster of an office chair could provide the manufacturer with a full inventory of that part of the chair using the Supplier HPD. At the option of the chair manufacturer, this part inventory can now also be displayed in the Product HPD report, so that a designer using the HPD can see which materials are in the caster. Consistent with the approach of the HPD Open Standard, these tools allow for optional withholding of confidential business information.
More consistent and transparent reporting of substance data
The 4,600+ HPDs published to date provide a treasure trove of data about materials and substances used in building products and materials. Several innovations with HPD v2.2 make that data more consistent, easy to understand, and useful for research.
- The previous “Role” field on the HPD has been renamed “Substance Role,” and manufacturers will select from a drop-down list with dozens of possible terms such as binder, flame retardant, surfactant, biocide, etc. More consistent use of this field is important to understanding how a substance is being used. As collective use of HPDs continues to grow, researchers can use that data to identify which substances are less hazardous for a given role.
- A new “Material Type” field will provide a broad classification of a material based on chemical makeup and molecular structure. Manufacturers will select from a list of options the most accurate classification describing a material. Typical entries may include Metal, Ceramic, Polymeric Material, Glass, etc. The purpose of this field is to help HPD users read an HPD and to gain a picture of what kinds of materials they are working with and how the product fits together.
- In another new requirement, when manufacturers provide notes in the HPD with qualifications related to context, e.g., chemical exposure or risk assessment, the manufacturer will now be directed to provide specific citations to relevant published reports. This will support HPD users in researching and verifying Notes statements.
Continued compliance with LEED v4
All versions of the HPD are recognized for contribution to the LEED v4 and now LEED v4.1 material ingredients credits. HPD v2.2 remains consistent with LEED requirements, and HPDC regularly updates LEED guidance on its website to support updates in the HPD and in LEED.
HPD v2.2 continues to provide an automated LEED Pre-Check to review compliance of HPDs with LEED v4 requirements. In a procedural revision, the pre-check has been published separately as part of HPDC’s Emerging Best Practices. This allows HPDC to update the pre-check to align with LEED’s revision cycles, and to more readily add pre-checks for other programs when there is demand. For example, HPDC is now building a LEED v4.1 Pre-Check.
Support for product variations and reformulations
In response to manufacturer feedback, HPD v2.2 better recognizes the typical variation that occurs in products through a number of revisions.
- Most significantly, HPDC’s Technical Committee has provided specific instructions to allow manufacturers of modular components or products with consistent composition but widely varying ingredient proportion to report these variations using a single HPD. Think of a company making cables that can vary from 1 to 50 meters long. Under previous versions of the HPD Open Standard, each incremental change would require its own HPD, even though it is basically the same product.

Implemented with Errata
When initially released, HPD v2.2 included a new system for multiple “Issuances” of an HPD for the same product. That aspect of HPD v2.2 has been removed as of the implementation of HPD v2.2 in the HPD Builder. HPDC plans a new approach to this same issue in HPD v3. HPD v3 is planned with a new structure which will better accommodate this and other related features.
