Verify a certificate

Lookup

Check a lot number, a certificate number or a product code against the register. One query returns one record — what it was certified against, on which analyte panel, in which basis, and whether that certificate is in force today.

Look up a certificate

Three routes into the same record. A lot number is the one printed on the pack; a certificate number appears on the license and in brand communications; a product code is the GTIN or UPC.

Lot number

Printed on the pack, usually near the best-before date.

L2604-118A
Certificate number

On the license and in the brand’s permissions letter.

HMTC-IF-0001
Product code

The GTIN or UPC as sold at retail.

The register is not browsable. A query must identify a single product or certificate; there is no wildcard search and no multi-brand listing, which is a deliberate constraint on membership enumeration rather than a limitation of the interface.

The record

Specimen — no certificates issued yet

The register opens with the first certificate issued against a published subcategory standard. The record below shows the shape a real result takes, with a placeholder holder name. It is a specimen, not a certified product.

Threshold values are deliberately absent here. The certificate asserts conformity to a named, versioned standard; the numbers live on that standard so a single source governs them.

What this record asserts: that the named product was tested at or below every value in the named standard, on the stated analyte panel, in the stated basis, by an accredited laboratory, within the stated period. What it does not assert: that the product is safe, that analytes outside the panel were controlled, or anything at all about a product form other than the one named.

Lot surveillance

Certification is continuous, not a single pass. Each lot tested under the program appears here with its date, its laboratory and the panel run — the contemporaneous, independent record that makes a certificate defensible years later.

Specimen rows. Outcome is stated as conformity to the standard in force at the sampling date, never as a measured concentration — per-lot values are the brand’s confidential data and are not published.

For regulators

A regulator or a state attorney general needs three things from a certifier: the standard a product was held to, the evidence that standard rests on, and the ability to check both without asking permission. All three are public here.

The standard, in full

Every threshold, its pooled value before rounding, the rationale tag, the contributing source count and the sensitivity band. Published, versioned and dated.

The evidence beneath it

Each limit traces to source records on the Heavy Metal Index, which is operated separately and does not depend on this program.

The gap, named

Where a limit sits tighter or looser than the literature strictly supports, the standard says so and says why. Nothing is asserted as settled that is not.

The conformity record

Lot-level laboratory reports and chain of custody are produced to a regulator on request, without a subpoena.

Requests for the full lot-level record behind a certificate — including laboratory reports and chain of custody — are handled directly. The program does not require a subpoena to produce its own conformity evidence to a regulator.
