An <strong>audit<\/strong> examines a system or site. <strong>Certification<\/strong> is a formal statement issued by a certifying body. A <strong>scope certificate<\/strong> confirms that a supplier\u2019s system, site, or product range is eligible to make a claim. A <strong>transaction certificate<\/strong> confirms that a specific shipment, lot, or order qualifies. <strong>Substantiation<\/strong> is the evidence base that supports a claim before it is made. <strong>Chain of custody<\/strong> is the documented trail linking a material from origin through each transfer to the final product. A <strong>change notification<\/strong> is a supplier\u2019s formal notice that something affecting a verified claim has changed.<\/p>\n<p>One constraint shapes the rest of this guide. Evidence quality varies by claim type, and some absolute absence claims cannot be fully substantiated with current methods.<\/p>\n<h2>What Is Required for Verification of a Supplier Claim? The Minimum Supplier Evidence Package<\/h2>\n<p>A complete supplier evidence package follows the same structure for every claim type. If any required item is missing, the claim remains unsubstantiated, regardless of how credible the supplier appears.<\/p>\n<ol>\n<li>\n<p>The claim in its exact wording, as it will appear on packaging, marketing, or a specification sheet.<\/p>\n<\/li>\n<li>\n<p>The product scope the claim covers, such as a specific SKU, model, or product line, rather than a vague \u201cour products.\u201d<\/p>\n<\/li>\n<li>\n<p>The legal entity and manufacturing site responsible for the claim.<\/p>\n<\/li>\n<li>\n<p>The basis of the claim, meaning the standard, method, or regulation used to measure it.<\/p>\n<\/li>\n<li>\n<p>The issuing body, laboratory, or certifier, including its accreditation reference.<\/p>\n<\/li>\n<li>\n<p>The analytical or assessment method used, along with its validated range or scope.<\/p>\n<\/li>\n<li>\n<p>The results, reporting limits, and the acceptance criteria applied.<\/p>\n<\/li>\n<li>\n<p>The validity dates, including issue date and expiration or re-verification date.<\/p>\n<\/li>\n<li>\n<p>The traceability link from the certificate or report to the specific order, lot, or shipment.<\/p>\n<\/li>\n<li>\n<p>A signed supplier declaration of accuracy and completeness.<\/p>\n<\/li>\n<li>\n<p>A change-control commitment that defines what the supplier must notify the buyer about and when.<\/p>\n<\/li>\n<li>\n<p>The current verification status, such as active, suspended, expired, or withdrawn.<\/p>\n<\/li>\n<\/ol>\n<p>Under FDA food safety regulations (21 CFR 117.430), supplier verification activities must occur before first use and then periodically. This model works well even outside the food sector, because it treats verification as an ongoing control rather than a one-time approval.<\/p>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\">Get a plastic-free certification pathway for your company.<\/a><\/p>\n<p>One distinction inside that evidence package causes more verification failures than almost any other: the difference between a scope certificate and a transaction certificate.<\/p>\n<h2>Scope Certificate vs. Transaction Certificate: What Each Actually Covers<\/h2>\n<p>A scope certificate (SC) confirms that a supplier\u2019s system, site, or product range is eligible to make a claim. A transaction certificate (TC) confirms that a specific shipment, lot, or order qualifies under that claim. These documents serve different purposes and buyers need both types in the right situations.<\/p>\n<p>The operational rule stays simple. A scope certificate alone never covers a specific shipment. Buyers who accept a scope certificate as proof of an order-level claim rely on eligibility evidence instead of shipment evidence. That gap often survives routine document review and appears only when a claim faces a challenge.<\/p>\n<p>For any order-level claim, require the transaction certificate or equivalent lot-specific evidence. Confirm that the certificate number, issuing body, validity window, and scope match the purchase order. A GRS scope certificate proves a company is certified to produce GRS-compliant products, while a GRS transaction certificate ties a specific shipment to the standard. The GRS scope certificate itself states that it provides no proof that delivered goods are GRS-certified. Transaction certificates carry that proof. <\/p>\n<p>The same pattern applies to recycled content, organic, chain-of-custody, and plastic-related claims. A practical check starts with the issuing body\u2019s public registry. Verify the certificate number and holder name there, because a certificate that cannot be independently verified should not be accepted at face value. Then confirm that the scope covers the exact product category ordered and match the validity window against the shipment date. A certificate that is real but out of scope or expired still fails the order-level test.<\/p>\n<h2>Claim-Type Evidence Matrix: How To Use Evidence by Claim Category<\/h2>\n<p>The same three questions apply to every claim type: what counts as adequate evidence, what falls short, and what should trigger escalation. The table below shows how those answers change by category so you can compare what you have against what you actually need.<\/p>\n<figure style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/cdn.aigrowthmarketer.co\/1784829410323-fb401fc7b1e4.webp\" alt=\"Colorful plastic fragments in water inside a laboratory petri dish.\" style=\"max-height: 500px\" loading=\"lazy\"><figcaption><em>Microplastics are particles smaller than five millimeters.

A simple three-tier model helps buyers match their review depth to actual risk.<\/p>\n<p><strong>Document review<\/strong> works for low-exposure claims when the certificate is independently verifiable and the scope matches the order. This tier fits routine reorders from established, qualified suppliers with current, scope-matched certificates.<\/p>\n<p><strong>Independent verification<\/strong> is appropriate when the claim is market-facing, the evidence is self-reported, or the claim type has no shared standard. As noted earlier, plastic and microplastic claims lack a US federal standard, so self-reported results carry less weight and need independent review. A raw lab report alone does not create a defensible market claim.<\/p>\n<figure style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/cdn.aigrowthmarketer.co\/1784829453151-0debb98043a6.webp\" alt=\"A single water droplet creating concentric ripples on a blue surface.\" style=\"max-height: 500px\" loading=\"lazy\"><figcaption><em>A credible conversation about plastics in water depends on measurement and standards that don&#8217;t yet exist for the category.

Absolute absence claims such as \u201ccontains no X\u201d sit in this category, because no current method can confirm complete absence across every particle size, polymer type, and production lot.<\/p>\n<figure style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/cdn.aigrowthmarketer.co\/1784829388732-c6255482b477.webp\" alt=\"Fragments of plastic suspended in blue water below the surface.\" style=\"max-height: 500px\" loading=\"lazy\"><figcaption><em>Plastic doesn&#8217;t disappear \u2014 it fragments.

These include mismatched legal names across bank accounts, invoices, and certificates, expired or out-of-scope certificates, scope certificates presented as order-level proof, and benchmark claims with no comparative data.<\/p>\n<h2>Change Notification and Re-Verification Triggers<\/h2>\n<p>A claim remains valid only for the scope, period, and inputs used during verification. Any change to those inputs suspends the claim until a new review confirms it again. The following changes should trigger supplier notification and buyer re-verification.<\/p>\n<ul>\n<li>\n<p>Raw material or feedstock change<\/p>\n<\/li>\n<li>\n<p>Formulation change<\/p>\n<\/li>\n<li>\n<p>Manufacturing site change<\/p>\n<\/li>\n<li>\n<p>Process change<\/p>\n<\/li>\n<li>\n<p>Certification status change, including suspension, withdrawal, or expiration<\/p>\n<\/li>\n<li>\n<p>Country-of-origin change<\/p>\n<\/li>\n<\/ul>\n<p>Supplier agreements should define re-verification cadence and notification timelines in advance. A common industry practice is 30 days\u2019 advance notice for major changes and immediate notice for safety or regulatory events. Treat expired evidence as absent evidence. Supplier quality frameworks consistently stress that qualification without ongoing monitoring functions as a credential rather than a control.<\/p>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\">See how a plastic-free certification pathway fits your supplier verification process.<\/a><\/p>\n<h2>Supplier Declaration vs. Independent Verification<\/h2>\n<p>A supplier declaration is a signed statement of accuracy and completeness. It forms a necessary part of the minimum evidence package, yet it carries no independent review and the market treats self-reported results as marketing, even when the underlying work is rigorous.<\/p>\n<p>Independent verification reviews the supplier\u2019s evidence against published criteria by a party with no stake in the outcome. For most claim types, an accredited certification body or recognized scheme fills this role. As noted earlier, plastic and microplastic claims lack a US federal standard, so no shared independent review pathway exists by default and self-reported results carry reduced weight.<\/p>\n<p>The Wellness Quality Institute\u2019s Plastic-Free Pathway Verification provides an independent review pathway for plastic-related claims. The Wellness Quality Institute reviews a company\u2019s existing independent laboratory dataset, testing methodology, product scope, and supporting controls against WQI-CS-01, which aligns with the California State Water Board\u2019s drinking-water microplastics reference framework. The Wellness Quality Institute does not run laboratory tests and does not certify that any product is free of plastic.<\/p>\n<figure style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/cdn.aigrowthmarketer.co\/1784829434095-0fc8fbcf29fa.webp\" alt=\"Scientists in white coats working with samples and microscopes in a laboratory.\" style=\"max-height: 500px\" loading=\"lazy\"><figcaption><em>Only a small number of laboratories can genuinely test for microplastics, and capability varies by instrument and method. WQI reviews a company&#8217;s existing third-party laboratory data against a defined standard \u2014 it does not run the tests itself.<\/em><\/figcaption><\/figure>\n<p>Every review produces one of two outcomes. Standard Met carries a verification decision, a scope-locked license to use the WQI logo, a public registry listing, and approved claim language. Standard Not Met is a private outcome that is never described as a failed product and can be resubmitted. Verification is locked to the reviewed product, dataset, tested particle-size range, polymer panel, and production period. A single assessment fee covers review, verification decision, and registry listing, while independent laboratory testing is arranged and billed separately by a qualified independent laboratory.<\/p>\n<p><em>The Wellness Quality Institute Plastic-Free Pathway Verification does not certify that a product contains zero plastic, microplastics, or nanoplastics. It shows that the company is on a verified pathway toward plastic-free standards. Verification applies only to the reviewed products, submitted datasets, tested ranges, polymer panels, production or sampling periods, and supporting controls. The Wellness Quality Institute verification is not a California approval, government certification, or health or safety certification.<\/em><\/p>\n<h2>Red Flags and Common Failure Points<\/h2>\n<p>Certain failure patterns appear repeatedly in supplier claim reviews and deserve immediate escalation.<\/p>\n<ul>\n<li>\n<p><strong>Mismatched legal names across bank accounts, invoices, and certificates.<\/strong> Early warning: the supplier name on the certificate differs from the invoicing entity. Likely cause: a trading name used in place of the registered legal name. Correction: require the registered legal name on all documents and verify it against a public registry.<\/p>\n<\/li>\n<li>\n<p><strong>Expired or out-of-scope certificates.<\/strong> Early warning: the validity date has passed or the scope does not cover the product ordered. Likely cause: the certificate was not renewed or the scope was not updated after a product change. Correction: require a current certificate with scope that explicitly covers the ordered product before release.<\/p>\n<\/li>\n<li>\n<p><strong>Scope certificates presented as order-level proof.<\/strong> Early warning: the supplier provides only a scope certificate when a transaction certificate is required. Likely cause: the buyer has not specified the requirement. Correction: state in the purchase order that a transaction certificate is required for every shipment.<\/p>\n<\/li>\n<li>\n<p><strong>Benchmark claims with no comparative data.<\/strong> Early warning: the claim uses language such as \u201clower than,\u201d \u201creduced,\u201d or \u201cbetter than\u201d with no named comparator or dataset. Likely cause: marketing language adopted without substantiation review. Correction: require the named comparator, the method, and the result before approving the claim.<\/p>\n<\/li>\n<li>\n<p><strong>\u201cNone detected\u201d results presented without tested range, polymer panel, or reporting limits.<\/strong> Early warning: a plastic or microplastic claim rests on a single \u201cnone detected\u201d statement with no method context. Likely cause: a lab report treated as a market claim without independent review. Correction: require the tested particle-size range, polymer panel, reporting limits, and an independently reviewed dataset before accepting the claim.<\/p>\n<\/li>\n<\/ul>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\">Talk to WQI about verifying your plastic-related claims before you approve them.<\/a><\/p>\n<p>The following questions address the issues buyers raise most often when they apply these verification requirements in real purchasing decisions.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>What Is Required for Verification of a Supplier Claim?<\/h3>\n<p>The minimum package is the twelve-item list covered earlier in this guide. Use that list as your standard checklist before approving any supplier claim.<\/p>\n<h3>What Is the Difference Between Verification and Validation?<\/h3>\n<p>Verification confirms that a claim is supported by evidence against defined criteria and answers \u201cdoes the evidence support this claim?\u201d Validation confirms that a method or process performs as intended and answers \u201cdoes this method work correctly for this purpose?\u201d In supplier quality work, these terms describe different activities.<\/p>\n<h3>What Are the Common Methods of Supplier Claim Verification?<\/h3>\n<p>Four methods appear most often, in increasing order of assurance. Document review examines certificates, test reports, and declarations against defined acceptance criteria. Supplier questionnaires or self-assessments gather structured information and help with initial screening. Remote or desk audits review a supplier\u2019s quality system documentation without a site visit. On-site audits involve direct observation of processes, records, and controls at the supplier\u2019s facility. The appropriate method depends on the claim type, exposure level, and the buyer\u2019s ability to confirm performance through other means.<\/p>\n<h3>When Must a Supplier Claim Be Re-Verified?<\/h3>\n<p>Re-verification is required whenever any of the six change triggers listed earlier occurs or when the verification period expires. Treat expired evidence as absent evidence and pause claim use until re-verification is complete.<\/p>\n<h3>Does a Scope Certificate Cover a Specific Shipment?<\/h3>\n<p>A scope certificate confirms that a supplier\u2019s system or site is eligible to make a claim. It does not confirm that any specific shipment, lot, or order qualifies. For order-level claims, buyers need a transaction certificate or equivalent lot-specific evidence. As noted earlier, treating a scope certificate as shipment-level proof creates a common and serious verification gap.<\/p>\n<h3>How Do Plastic and Microplastic Claims Differ from Other Claim Types?<\/h3>\n<p>Plastic and microplastic claims lack a US federal standard, so no shared independent review pathway or agreed evidence definition exists by default. Adequate evidence for this claim type requires an independently reviewed dataset with a defined tested particle-size range, polymer panel, reporting limits, and scope lock. A \u201cnone detected\u201d result without those elements only shows that nothing was found above a specific size threshold using a specific method on a specific lot, rather than proving that no plastic is present.<\/p>\n<h2>Read Next<\/h2>\n<ul>\n<li>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\/articles\/require-verified-plastic-claims-suppliers\">How to Require Verified Plastic Claims from Suppliers<\/a><\/p>\n<\/li>\n<li>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\/articles\/supplier-verification-requirements-plastic-claims\">Supplier Verification Checklist for Plastic Claims<\/a><\/p>\n<\/li>\n<li>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\/articles\/supplier-sustainability-claim-verification-standards\">Supplier Sustainability Claim Verification Audit Guide<\/a><\/p>\n<\/li>\n<li>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\/articles\/supplier-sustainability-verification-programs\">Supplier Sustainability Verification: A Stronger Program<\/a><\/p>\n<\/li>\n<li>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.wellnessqualityinstitute.com\/articles\/third-party-claim-validation-standards\">Third-Party Claim Validation Standards for Product Claims<\/a><\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The Wellness Quality Institute explains what evidence you need to verify supplier claims and approve them with confidence.
