Quick answer: HPD Open Standard v3.0 is the current version of the Health Product Declaration standard, maintained by the Health Product Declaration Collaborative (HPDC) and implemented in the HPD Builder in September 2025. It moves HPDs from static PDFs to digital, modular records and adds six main capabilities: a PFAS Attestation and PFAS Screening Tool, a structured Metal Alloy inventory, hazard screening by EC number, an EU HPD output aligned with REACH, an expanded product type taxonomy, and optional social equity reporting. The core reporting rules (inventory methods, thresholds, and Characterized/Screened/Identified) are unchanged.
Key Takeaways
- Most of v3.0 is additive. The fundamentals of content inventory and hazard screening stay the same, so existing HPD data carries forward.
- Metal products are affected most. Manufacturers can now report alloys element by element, with each alloying element screened for hazards.
- PFAS disclosure is now possible below the reporting threshold through a new attestation feature.
- Product type classification changed. Recategorizing products improves how easily project teams find your HPDs in the Repository.
- Social equity fields are optional, but they are visible in the Repository and filterable by project teams.
What Is the HPD Open Standard?
The HPD Open Standard is a voluntary technical specification for reporting a building product’s contents and associated health information. A Health Product Declaration (HPD) lists a product’s materials and substances as delivered to the job site, screens those substances against authoritative hazard lists, and summarizes the results in a consistent format.
An HPD is not a certification, a label, a life-cycle assessment, or an Environmental Product Declaration (EPD). It does not rate one product as better than another. It reports data that project teams use to document compliance with programs including LEED, WELL, Cradle to Cradle Certified, and the Living Building Challenge.
According to HPDC, more than 18,000 HPDs covering over 40,000 building products from 800+ manufacturers have been published since the standard launched in 2012.

What Changed in HPD v3.0?
1. HPDs Are Now Digital, Modular Records
Under v2.3, an HPD was essentially a static PDF. In v3.0, HPDs become modular digital records connected to the HPD Builder and HPD Public Repository. This allows faster updates, API data sharing with design and certification tools, and a clearer separation between the standard itself and the tools that implement it.
What it means for manufacturers: Your HPD data now travels further. It can flow to HPDC’s API data partners and support scoring for programs like LEED v5 and WELL. Accurate, current data matters more than before, because errors propagate across platforms.
2. PFAS Attestation and PFAS Screening Tool
PFAS (per- and polyfluoroalkyl substances) are under growing regulatory and market pressure. v3.0 adds two tools:
- PFAS Attestation: Manufacturers can declare whether intentionally added PFAS are present even when they fall below the HPD’s reporting threshold. The form includes fields for the type of PFAS, its function in the product, alternatives explored, and supporting documentation such as lab results or supplier declarations.
- PFAS Screening Tool: Built into the Builder’s hazard screening, it flags substances that match the Green Science Policy Institute’s PFAS class list based on CAS numbers.
What it means for manufacturers: Before v3.0, a PFAS present at 50 ppm in a product reported to a 100 ppm threshold was invisible in the HPD. Now there is a formal way to disclose it, and project teams can filter the Repository by PFAS declaration. Manufacturers who can credibly attest to no intentionally added PFAS gain a visible advantage.
3. Metal Alloy Special Condition with Element-Level Inventory
Previously, the Metal Alloy Special Condition could only be used with a trade association metal alloy HPD, so most manufacturers didn’t use it. v3.0 introduces a structured Alloying Element Inventory: you enter each alloying element (for example, chromium, nickel, or molybdenum), its weight percentage, and its role. Each element is screened for hazards individually, and inventories can be copied between HPDs. HPDC’s Manufacturer Guide notes this aligns alloy reporting with LEED v5.
What it means for manufacturers: If your products contain stainless steel, brass, aluminum alloys, or other metals, this is likely the most significant v3.0 update for you. Replace free-text alloy descriptions with structured element data.
4. Hazard Screening by EC Number
The HPD Builder now accepts European Community (EC) numbers as well as CAS Registry Numbers for hazard screening through the Pharos Chemical and Materials Library.
What it means for manufacturers: If your EU-based suppliers only provide EC numbers, you can screen without tracking down CAS RNs. Remember that using the wrong identifier still produces inaccurate screening, so confirm the identifier matches the exact substance in your product.
5. The EU HPD
v3.0 introduces the first regional adaptation of the HPD. The EU HPD uses the same underlying data but presents it for European specifiers, highlighting Substances of Very High Concern (SVHCs), REACH compliance status, and certifications recognized in the EU.
What it means for manufacturers: Companies selling into Europe can use one dataset for both North American and European procurement, rather than maintaining separate disclosure documents.
6. Expanded Product Type Taxonomy
Product type categories are now more granular and harmonized with the Athena Sustainable Materials Institute’s classifications. The Repository’s search filters reflect the new taxonomy.
What it means for manufacturers: Product type drives discoverability. A miscategorized product is harder for project teams to find. Review your product type selection when you update each HPD.
7. Social Equity Certifications and Survey (Optional)
Section 3 now includes optional fields for social equity certifications such as the JUST label, B Corp, and Fair Trade, with space to upload or link to supporting evidence. A new Social Equity Survey tab collects voluntary, self-reported information on workplace equity, supply chain labor practices, and community investment.
What it means for manufacturers: These fields aren’t required for a compliant HPD. But Repository dashboards let project teams filter by social equity participation, so leaving them blank may reduce visibility for ESG-focused buyers.
8. Upgraded Repository Dashboards
Repository dashboards now include visual hazard displays, inventory completeness views, and clear status labels showing whether an HPD is Third-Party Prepared, Third-Party Verified, or includes Special Conditions.
What it means for manufacturers: Verification status is now visible at a glance. If you’ve been considering HPDC’s Third-Party Verification program, v3.0 makes the benefit more obvious to project teams.
What Didn’t Change in HPD v3.0
The core methodology in HPDC’s Manufacturer Guide still applies:
- Three inventory methods: Nested Materials Inventory with material-level thresholds, Nested Materials Inventory with a product-level threshold, and Basic Inventory with a product-level threshold. Choose early, because switching methods in the Builder means redoing work.
- Thresholds: 100 ppm (0.01%) is more stringent than 1,000 ppm (0.1%). LEED Option 2 requires reporting to 100 ppm with no GreenScreen Benchmark-1 or List Translator-1 substances.
- Characterized, Screened, Identified: You can still withhold a proprietary substance’s name and CAS RN, as long as its amount and role are reported and it is screened for hazards.
- Ranges: Quantities can be reported as ranges up to 20% to protect formulations. Wider ranges require an explanation in the Notes.
- Publishing: An HPD is only officially “published” when it appears in the HPD Public Repository.
- SDS limits: Safety Data Sheets alone don’t meet LEED thresholds and omit many substances an HPD requires.
HPD v3.0 Update Checklist for Manufacturers
Use this list when updating existing HPDs or creating new ones in the HPD Builder:
- Review product type against the expanded taxonomy and reclassify if needed.
- Rebuild metal alloy reporting using the Alloying Element Inventory (element, weight %, role) for any metal materials.
- Collect PFAS documentation from suppliers (declarations or lab test results) and decide whether to complete the PFAS Attestation.
- Check PFAS Screening results for any flagged substances and add context in Substance Notes.
- Confirm identifiers (CAS RN or EC number) are correct for the exact substance used.
- Update supplier requests to ask for PFAS status, alloy composition, and EC numbers where relevant. The Supplier HPD remains the most efficient way to collect this.
- Add social equity certifications in Section 3 if you hold any, and consider completing the survey tab.
- Evaluate EU HPD output if you sell in Europe.
- Consider Third-Party Verification, since verification status now appears prominently in Repository dashboards and earns extra credit in LEED v4.1.
- Run the Builder’s completeness check and LEED Pre-Check before publishing to the Repository.
