Cosmetic Heavy Metals Test

Instrumental analysis of lead, arsenic, cadmium, mercury, and other heavy-metal impurities in finished cosmetics, assessed against FDA's points of attention on heavy-metal impurities to support safety substantiation and platform compliance.

What this service is

Heavy metals testing uses instrumental analysis to measure impurities such as lead, arsenic, cadmium, and mercury in cosmetics. These elements mainly arrive as trace impurities in raw materials and colorants, and FDA has published guidance addressing their levels in cosmetics.

Heavy metals data is a common supporting item in a MoCRA safety substantiation file and a frequent requirement in marketplace review and buyer audits.

FD&C Act §601MoCRA (2022)

Who needs it

Cosmetic companies exporting to the U.S. that need heavy metals data
Products heavy in mineral-derived ingredients or colorants (makeup, lip products, etc.)
Brands asked by platforms or buyers for heavy metals test reports

Prerequisites and sequence

  • Provide finished-product samples.
  • If the product contains specific colorants or mineral ingredients, the ingredient list helps define the test scope.

Who holds regulatory responsibility

Control of heavy-metal impurities rests with the manufacturer. We coordinate the laboratory test and interpret the results; impurity control at the raw-material level sits with you and your suppliers.

Materials we need from you

Sufficient finished-product samples
Complete formula or main ingredient list
Colorant usage details (for color cosmetics)
Preferred element scope, if specified

Process

  1. 01

    Define the element scope based on product type

  2. 02

    Ship samples to the partner laboratory

  3. 03

    Instrumental analysis at the laboratory

  4. 04

    Obtain the data

  5. 05

    Interpret results against reference limits and deliver the report

Deliverables

Heavy metals test report (with measured values per element)
Interpretation note against reference limits

Timeline

Instrumental analysis is relatively quick; the overall turnaround is typically within a few weeks, subject to laboratory scheduling.

Scope

What we provide

  • Test scope confirmation and shipping guidance
  • Laboratory coordination
  • Report delivery and result interpretation

What is not included

  • Raw-material investigation and product remediation after an out-of-spec result
  • Batch-level incoming inspection of raw materials
  • International sample shipping costs

Common pitfalls

Relying on raw-material COAs instead of finished-product testingA raw-material COA reflects a single batch of that ingredient; the actual level in the finished product depends on the full formula. Only finished-product testing confirms the real level.
Not tracing an out-of-spec result back to raw materialsHeavy metals mainly arrive as trace impurities in raw materials and colorants, especially mineral-derived ones. Repeatedly testing the finished product without tracing the source solves nothing.
Assuming no universal limit means no testing is neededFDA has issued guidance-level limits for lead in products such as lip cosmetics; other elements are managed under impurity-control principles. The absence of a single universal limit does not remove the expectation — platforms and buyers routinely ask for data.

FAQ

Does the U.S. set limits for heavy metals in cosmetics?

FDA has issued guidance-level limits for lead in products such as lip cosmetics; other elements are generally managed under impurity-control principles. Results are interpreted against the references applicable to your product type.

Where do heavy metals come from?

Mainly trace impurities carried in by raw materials and colorants, especially mineral-derived ingredients. An out-of-spec finished product usually requires tracing back to the raw materials.

If raw materials come with certificates, do we still test the finished product?

A raw-material COA reflects a single batch of that ingredient; only finished-product testing confirms the actual level in the final product. The two do not replace each other.
