Most supplement brands talk about testing. Very few show you exactly what that testing involves, who does it, and what the results actually confirm.
Eurofins Scientific is one of the most recognised independent testing laboratories in the world. When a Shilajit brand says their product is Eurofins tested, that claim carries real weight — but only if you understand what Eurofins actually does and what their reports confirm.
This article breaks down the Eurofins testing process for Shilajit, explains what each test category covers, and shows you how to use that information to make a genuinely informed purchase decision.
Who Is Eurofins Scientific?
Eurofins Scientific is a Luxembourg-based international group of laboratories operating in over 60 countries. They employ more than 62,000 people and run over 900 laboratories worldwide.
They are not a supplement marketing company. They are an analytical testing organisation. Their business is producing accurate, defensible laboratory results for food, pharmaceuticals, environmental samples, and consumer products — including dietary supplements.
Eurofins holds ISO/IEC 17025 accreditation, which is the international standard for testing and calibration laboratories. This accreditation means their methods are validated, their equipment is calibrated, and their results are reproducible. It is the benchmark that regulators, courts, and industry bodies rely on when they need results they can trust.
When a Shilajit brand publishes a COA from Eurofins, they are publishing results from one of the most credible testing networks on earth. That is meaningfully different from a brand that tests in-house or uses an unaccredited third party.
Why Shilajit Specifically Needs Independent Testing
Shilajit is a complex natural substance. It forms over millions of years as organic matter decomposes under mountain rock, absorbing minerals from the surrounding geology. That process produces a resin rich in fulvic acid, humic acid, and over 80 trace minerals.
It also means raw Shilajit can absorb contaminants from its environment — including heavy metals, microbial organisms, and environmental pollutants depending on where and how it was collected.
The supplement market for Shilajit is largely unregulated in most countries. A brand can source raw material from almost anywhere, process it minimally, and sell it with bold claims. Without independent testing, there is no way for a buyer to verify what is actually in the product.
This is why Eurofins testing matters. It removes the brand from the equation and replaces their claims with independently verified data.
What Eurofins Tests for in Shilajit
Heavy Metal Analysis
This is the most critical test category for Shilajit. Because the resin forms in geological environments, it can naturally accumulate lead, arsenic, mercury, and cadmium from surrounding rock strata.
Eurofins uses Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to detect heavy metals. ICP-MS is one of the most sensitive analytical techniques available, capable of detecting metals at parts per billion (ppb) concentrations. It is the method of choice for regulatory agencies and pharmaceutical manufacturers.
The test reports detected levels for each metal alongside the applicable regulatory limit. A passing result means the detected level falls below the threshold set by the relevant standard — whether that is California Prop 65, USP, or EU Maximum Levels.
For a well-purified Himalayan Shilajit resin, you should expect to see:
- Lead: Below 0.5 µg per daily serving
- Arsenic: Below 10 µg per daily serving
- Mercury: Below 0.3 µg per daily serving
- Cadmium: Below 4.1 µg per daily serving
Microbial Testing
Raw Shilajit collected from mountain rock faces is exposed to environmental microorganisms. Without proper purification and microbial testing, a finished product could carry bacterial contamination.
Eurofins tests for:
- Total Aerobic Plate Count (TAPC) — the overall bacterial load
- Yeast and mould — fungal contamination
- Coliforms and E. coli — indicators of faecal contamination
- Salmonella — a key pathogen in food and supplement safety
Pesticide Residue Screening
Although Shilajit is not an agricultural product, it can be exposed to pesticides through environmental runoff, particularly if collected from lower altitudes near farming activity.
Eurofins screens for hundreds of pesticide compounds using Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS). These are the same techniques used by food safety regulators globally.
Solvent Residues
Some Shilajit processing methods use solvents to extract or purify the resin. Eurofins can test for residual solvents to confirm that the finished product does not carry processing chemical carry-over above safe limits.
Identity and Authenticity Verification
Eurofins can also perform identity testing to confirm that a product is what it claims to be. For Shilajit, this can include:
- Fulvic acid content — measured by spectrophotometric or HPLC methods
- Humic acid content — a secondary marker of Shilajit authenticity
- Mineral profile — confirming the characteristic trace mineral composition
A verified fulvic acid content of 40–55% by dry weight is consistent with high-quality purified Shilajit resin. Claims significantly above this range — 70%, 80%, or higher — are not supported by verified testing of authentic resin and should be treated with scepticism.
How to Read a Eurofins COA for Shilajit
Laboratory identification. The COA should clearly identify Eurofins as the issuing laboratory, including the specific Eurofins entity and their accreditation number.
Sample identification. The COA should reference the specific product batch or lot number.
Test date. Check when the analysis was performed. A COA from more than 12–18 months ago may not reflect the current batch.
Analyte, result, and limit columns. For each substance tested, the COA will show the detected level and the applicable limit. Results should be clearly marked as passing.
Authorised signatory. A legitimate Eurofins COA will be signed or stamped by an authorised laboratory representative.

Eurofins Testing vs BSCG Certification: How They Work Together
Eurofins is the laboratory. They perform the analytical work — running the instruments, producing the data, and issuing the COA.
BSCG (Banned Substances Control Group) is a certification programme. BSCG requires brands to test every batch against a panel of over 500 substances and to maintain that testing on an ongoing basis. BSCG audits the process, not just a single result.
Golden Shilajit Official maintains both. Every batch of purified Himalayan Shilajit resin and drops is tested through Eurofins and the product holds BSCG certification. The results are published openly on the Lab Reports page.
What Eurofins Testing Cannot Tell You
Testing is batch-specific. A COA confirms the results for the batch that was tested.
Testing confirms what was tested. Check what was actually tested, not just whether a COA exists.
Sample integrity matters. The sample submitted to Eurofins must accurately represent the finished product.
How Golden Shilajit Official Uses Eurofins Testing
Golden Shilajit Official sources purified Shilajit resin and drops from the Pakistan Himalayas. Every production batch is submitted to Eurofins for independent analysis covering heavy metals, microbial safety, and identity verification.
The COAs are published on the Lab Reports page without restriction.

FAQ: How Eurofins Tests Shilajit
Is Eurofins an accredited laboratory?
Yes. Eurofins holds ISO/IEC 17025 accreditation across its laboratory network, recognised by regulators, courts, and industry bodies globally.
What does ICP-MS mean on a Shilajit COA?
ICP-MS stands for Inductively Coupled Plasma Mass Spectrometry. It is one of the most sensitive analytical techniques for detecting heavy metals at parts per billion concentrations.
How often should a Shilajit brand test with Eurofins?
Ideally every production batch. BSCG certification requires ongoing batch-level testing, which is why it adds meaningful assurance beyond a one-time COA.
Can I verify a Eurofins COA is genuine?
Yes. Eurofins COAs include the laboratory’s accreditation number and contact details. You can contact Eurofins directly to verify.
What is the difference between Eurofins testing and BSCG certification?
Eurofins is the laboratory that performs the analytical testing. BSCG is a certification programme that audits the testing process independently.
Does a Eurofins COA guarantee a Shilajit product is safe?
A Eurofins COA confirms the tested batch met specified limits. It is the strongest form of independent verification available for supplements.
Why do some Shilajit brands not publish their COAs?
They may not test at all, test in-house only, or their results may not be favourable. A brand that tests with Eurofins and passes has every reason to publish openly.
Conclusion
Eurofins testing is not a marketing badge. It is a specific, rigorous analytical process carried out by one of the world’s most credible independent laboratories.
