How a Product Earns the Heavy Metal Certified Mark

Abstract

The Heavy Metal Certified mark is voluntary, and a brand has to ask for it one product at a time. The product is tested through an independent laboratory accredited to ISO/IEC 17025, compared with a published standard covering eight metals, and retested every year to keep the mark. This guide walks through each step so parents know what the mark reflects and brands know what to expect.

A product can only carry the Heavy Metal Certified mark after the brand asks for it, the product is tested through an independent laboratory, and the results meet a published standard. The mark then has to be renewed with retesting every year. Knowing those steps helps parents read the mark accurately, and it helps brands understand what they are signing up for.

Step 1: The brand chooses to apply

Certification is voluntary. No government agency requires it, and many good products carry no mark simply because the brand has never applied. The process usually starts with a conversation about which products are in scope, because certification is granted one product at a time, not to a whole brand.

Step 2: The product is tested through an independent lab

Testing is done through a qualified independent laboratory accredited to ISO/IEC 17025, the international standard for testing labs. The brand does not grade its own results. The Paleo Foundation runs the Heavy Metal Tested program as a certification organization. It is not a lab and not a government agency.

Step 3: Results are compared with a published standard

The standard covers eight metals: lead, arsenic, cadmium, mercury, chromium, nickel, tin, and aluminum. The limits are public, so anyone can read them on Heavy Metal Certified. A product that meets the standard can be licensed to use the mark. A product that does not meet it does not get the mark. When a product does not meet the standard.

Step 4: The mark is licensed for that product

The mark applies to the exact product that was tested. A certified pouch does not mean the rest of the brand's catalog is certified, and a certified adult supplement does not cover a children's version.

Step 5: The product is retested every year

Certification lasts one year. To keep the mark, the product has to be retested and meet the standard again. If it does not, the mark is not renewed. Annual recertification.

What this means for parents

When you see the mark, you know that specific product was tested by an independent lab within the last year and met a published standard. You do not know that the food has zero metals, because trace amounts are in almost all food. The mark is also not a medical judgment or a safety guarantee. If you have questions about a specific product, ask the brand when it was last certified. What the mark means.

A product without the mark has not failed anything. Most products have never been submitted for certification. Posted lot results, such as the QR codes California requires on many baby food packages, are another useful source. QR batch data vs a certification mark.

What this means for brands

Before applying, it helps to have a short list of the products you want certified, their formats (pouches, cereals, snacks, drinks, or supplements), any lot testing you already run, and who in your company owns on-pack claims. Be ready for the possibility that a product will not meet the standard at first testing or at a yearly retest. Certification does not replace any legal testing or disclosure duty your products already have. Lot testing vs certification.
