Short answer: A LEED Pre-Checked HPD and a third-party verified HPD are not the same thing, and they are not competing options. The LEED Pre-Check is a free, automated check inside the HPD Builder that flags whether required fields line up with LEED Material Ingredients criteria. Third-party verification is a separate, paid desk audit by an HPDC-approved verifier that confirms the HPD’s content inventory matches supporting documentation. Elixir Environmental, a consultancy that helps building product manufacturers develop Health Product Declarations (HPDs) for LEED, WELL, and CHPS, frames the decision around LEED value: the Pre-Check helps an HPD qualify, while verification increases how much the product counts toward credits. Elixir Environmental also helps manufacturers with HPD verification by working with HPDC Approved Third-Party Verifiers.
Key Takeaways
- The LEED Pre-Check has no separate fee and runs automatically in the HPD Builder, but it does not confirm that the data is accurate.
- Third-party verification adds a verifier fee and an extra review step, but under LEED v4.1 a verified HPD counts as 1.5 products instead of 1 toward Material Ingredients Option 1.
- Verification is required for most LEED v4.1 Material Ingredients Option 2 paths.
- Under LEED v5, verification, a 100 ppm inventory, and avoidance of specified hazards are required to reach Level 2 (2x value) in the Human Health criteria area.
- Most manufacturers should run the Pre-Check on every HPD and pursue verification for products that are frequently specified on LEED projects.

What Is a LEED Pre-Checked HPD?
According to the Health Product Declaration Collaborative (HPDC) Manufacturer Guide to the HPD Open Standard v3.0, the LEED Pre-Check Indicator was introduced in HPD v2.2 as an optional cross-check selected by the manufacturer. It checks whether required fields are complete and whether basic requirements of the LEED Material Ingredients credit are met, such as whether the correct threshold (100 ppm or 1,000 ppm) is indicated and whether all contents are Characterized, Screened, and Identified as required. The Pre-Check was later updated to reflect LEED v4.1 criteria.
The Guide is explicit about its limits. The Pre-Check does not assess data quality and does not verify that information is accurate. It is a preliminary scan. If an HPD does not pass, the manufacturer can correct the fields, or publish the HPD without disclosing the Pre-Check result.
For project teams, the Pre-Check is a sorting tool. HPDC’s support guidance explains that the only change to Material Ingredients Option 1 between LEED v4 and v4.1 is the 1.5x value for verification, so teams can use the LEED v4 Pre-Check to find Option 1 compliant HPDs, then filter the HPD Public Repository for verified HPDs that carry the added value.
What Is a Third-Party Verified HPD?
Third-party verification is an independent review of a completed HPD. Under the HPDC Third-Party Verification Program, verification is a separate process from preparation. The manufacturer starts it after the HPD is finished by contracting with an HPDC-approved verifier. Verifiers may also be HPDC Approved Preparers, but they cannot verify an HPD they helped prepare.
The review confirms that the HPD complies with the HPD Open Standard, that the product’s formulation reporting matches the documentation provided, and that any non-disclosed proprietary ingredients are accurately represented. The HPDC Manufacturer Guide notes that the program is consistent with ISO 17065 and that HPDC audits verifiers’ work to ensure quality.
It is equally important to understand what verification is not. It is a desk audit, not an on-site audit. Verifiers do not run laboratory tests or independently assess product contents or performance. Verification is not a product certification and does not declare a product to be safer.
Verified HPDs are visually distinct in the HPD format, carrying a third-party verified indicator that project teams and LEED reviewers look for, and verification status can be filtered in the HPD Public Repository.
Cost: What Each Option Adds
Pre-Check cost
The Pre-Check has no separate fee because it is a feature of the HPD Builder. The cost is Builder access itself. Unlimited Builder use is included with HPDC membership. Non-members can purchase a three-HPD token bundle, and HPDC will credit one bundle toward annual membership dues if the manufacturer upgrades within the allowed window.
Verification cost
HPDC does not publish a standard verification fee. Each approved verifier sets its own process and pricing. Common cost drivers include product complexity, the number of materials and substances, how many proprietary ingredients must be checked, and how well organized the supporting documentation is. Manufacturers should request quotes from approved verifiers directly or work through a preparer, such as Elixir Environmental, that coordinates with them.
The hidden cost of skipping verification
An unverified HPD can still be specified, but it earns less weight under LEED v4.1 and cannot reach Level 2 in the LEED v5 Human Health criteria area. That can reduce specification opportunities on LEED-driven projects.
Timeline: How Long Each Takes
Pre-Check: It runs inside the HPD Builder during drafting and publishing, so it adds essentially no time.
HPD preparation: Timelines depend mostly on the supply chain. The HPDC Manufacturer Guide notes that a simple product with a small, cooperative supply chain can be completed quickly, while complex products with multi-tiered supply chains take much longer because a Bill of Materials rarely reaches the substance level. Supplier requests, non-disclosure agreements, and residual and impurity research are the usual sources of delay.
Verification: Verification can only begin after the HPD is complete, so it adds a sequential review step. Its length depends on the verifier’s schedule and on how quickly the manufacturer can supply documentation such as Supplier HPDs, Safety Data Sheets, certificates of analysis, and formulation records. Organizing these records during preparation shortens the verification cycle considerably.
LEED Value: Where Verification Pays Off
LEED v4 and v4.1 Material Ingredients, Option 1
Option 1 rewards disclosure. Projects must use at least 20 different permanently installed products from at least five different manufacturers that demonstrate a chemical inventory to at least 0.1% (1,000 ppm). Most complete, published HPDs that pass the Pre-Check qualify. In LEED v4.1, third-party verified HPDs are worth 1.5 products each in the credit calculation instead of 1, which USGBC introduced to recognize the higher quality and effort behind verified reports.
LEED v4.1 Material Ingredients, Option 2
Option 2 rewards optimization, and here verification becomes a requirement rather than a bonus. Third-party verification is required for most Option 2 compliance paths. For example, the Advanced Inventory and Assessment path requires a chemical inventory to at least 0.01% (100 ppm), no GreenScreen LT-1 or GHS Category 1 hazards, and a third-party verified HPD or manufacturer inventory. A Pre-Checked but unverified HPD cannot satisfy this path.
LEED v5 Building Product Selection and Procurement
LEED v5 consolidates earlier material credits, including Material Ingredients, into one multi-attribute credit scored by achievement level. According to USGBC’s criteria resource for the credit, the Human Health criteria area works as follows:
- Level 1 (1x value): The product has a complete, published HPD with ingredients disclosed to at least 1,000 ppm and screened against authoritative hazard lists.
- Level 2 (2x value): The product is inventoried to 100 ppm, has third-party verification that includes the content inventory, and avoids specified hazardous ingredients.
- Level 3 (3x value): No qualifying Human Health documentation has been approved yet.
Scores from different criteria areas can be combined for multi-attribute products, up to a maximum of 5x per product. A verified HPD that reaches Level 2 therefore doubles a product’s Human Health contribution compared with an unverified HPD at Level 1.
Which Should a Manufacturer Choose?
Run the LEED Pre-Check on every HPD. It adds no fee, takes little time, and catches field-level problems that can lead to rejection by LEED reviewers.
Add third-party verification when any of the following apply:
- The product is regularly specified on LEED v4.1 or LEED v5 projects.
- The product can be inventoried to 100 ppm without GreenScreen LT-1 or GHS Category 1 hazards, making Option 2 or LEED v5 Level 2 realistic.
- Architects or owners on target projects prefer verified disclosure.
- The manufacturer also plans to pursue other programs, such as Declare, that can use verified HPD data.
A disclosure-only HPD with a passing Pre-Check remains a sensible first step when budgets are tight or the supply chain cannot yet support a 100 ppm inventory. As the HPDC Manufacturer Guide notes, a product that cannot meet Option 2 can still qualify under Option 1, which rewards disclosure rather than optimization.
What’s New in HPD v3.0 That Affects This Decision
HPD Open Standard v3.0 became the effective version in the HPD Builder on September 29, 2025, and all newly published HPDs now use it. HPDs created under earlier versions stay valid until their expiration dates and can be upgraded to v3.0 in the Builder. Changes relevant to LEED and verification include:
- A digitized, modular HPD format integrated with the HPD Builder and HPD Public Repository.
- Repository dashboards with verification status indicators and advanced filtering, which make verified HPDs easier for specifiers to find.
- A structured Alloying Element Inventory for metal alloys, replacing free-text reporting and aligning with LEED v5.
- Integrated PFAS tools, including a PFAS attestation for declaring PFAS below reporting thresholds and automated PFAS screening.
- Hazard screening support for European Community (EC) numbers and an expanded product type taxonomy.
Frequently Asked Questions
Does a LEED Pre-Check mean my HPD is LEED compliant?
Not definitively. It is a mechanical check of fields and thresholds. It does not verify data accuracy, and final compliance is determined during LEED review.
Is a third-party verified HPD a product certification?
No. Verification confirms that the HPD complies with the HPD Open Standard and matches supporting documentation. It does not certify the product as safer.
Can the same consultant prepare and verify my HPD?
No. An approved verifier cannot verify an HPD it helped prepare. Preparers such as Elixir Environmental coordinate with separate HPDC Approved Third-Party Verifiers.
How much is a verified HPD worth in LEED v4.1?
A verified HPD counts as 1.5 products toward Material Ingredients Option 1, compared with 1 product for an unverified HPD. Verification is also required for most Option 2 paths.
Do I need verification for LEED v5?
Not for Level 1 in the Human Health criteria area. Verification is required for Level 2, along with a 100 ppm inventory and avoidance of specified hazardous ingredients.
Where should verified HPDs be published?
In the HPD Public Repository, which the HPDC Manufacturer Guide identifies as the authoritative source for published HPDs. An HPD is not officially published unless it appears there.
How long is an HPD valid?
HPDs carry an expiration date shown on the report, and the HPD Open Standard explains how expiry and updates work. Manufacturers should plan to renew or update HPDs, and any verification, before they expire.
