Who performs the testing?

An independent laboratory unaffiliated with Himaal Pure. We do not present in-house numbers as third-party data.

How are heavy metals measured?

Via inductively coupled plasma mass spectrometry (ICP-MS), the industry-standard analytical technique for trace-metal detection. Lead, cadmium, arsenic and mercury are individually quantified.

What thresholds must a batch pass?

Fulvic acid ≥ 60%, humic acid ≥ 25%, and heavy metals within safe-consumption thresholds for mineral-based supplements. Failed batches do not become product.

Can I get the COA for my jar?

Yes. Email us with your order number or the batch ID printed on the label and we will share the corresponding Certificate of Analysis.

How long does testing take?

Standard turnaround is around 3–5 business days from sample submission, though it can extend if the lab is running additional confirmatory tests on a specific batch.

Are your test reports publicly published?

We share them on request rather than blanket-publishing them. Publication varies by batch (counterfeit prevention is part of the reason), but the data is always available to customers and partners.

Do you test for anything beyond fulvic, humic, minerals and heavy metals?

Additional tests — microbial, contaminant-specific, or solvent residue checks — are available on request, particularly for bulk and private-label partners.

Our lab testing protocol — what we measure, and why.

Every Himaal Pure batch is tested by an independent laboratory before it ever becomes packaged product. Here is the exact protocol.

Direct Answer

Our lab testing in one paragraph

Every batch of Himaal Pure Shilajit is sent to an independent laboratory for analysis on four fronts: fulvic acid content (target ≥ 60%), humic acid content (target ≥ 25%), a full mineral profile, and heavy-metal safety (lead, cadmium, arsenic, mercury). Only batches that pass become packaged product, and the Certificate of Analysis is available on request for the specific batch you received.

Tests run: fulvic acid, humic acid, mineral profile, heavy metals
Lab: independent (not in-house)
Frequency: per batch — not annual
Passing thresholds: fulvic ≥ 60%, humic ≥ 25%, heavy metals within safe limits
Output: batch-stamped COA

Step 1

Sample collection at the Kathmandu facility.

After raw Shilajit arrives in Kathmandu and is slow water-purified, a representative sample is drawn from each batch and sealed for transport to the testing laboratory. The sample never leaves our chain of custody until it reaches the lab.

Step 2

Fulvic & humic acid assay.

Fulvic acid is quantified using the standardised colourimetric protocol used in the supplement industry, calibrated against reference standards. Humic acid is quantified separately. We target ≥ 60% fulvic acid and ≥ 25% humic acid on every batch — numbers we will only publish because they are independently verified.

Step 3

Heavy-metal safety screen.

Lead, cadmium, arsenic and mercury are quantified using inductively coupled plasma mass spectrometry (ICP-MS), the standard analytical method for trace-metal detection. Each metal is checked against safe-consumption thresholds for mineral-based supplements. Any batch outside these thresholds is rejected — regardless of how strong its fulvic acid result was.

Step 4

Mineral profile.

The same ICP-MS workflow generates a full mineral profile: iron, magnesium, zinc, copper, selenium and other trace elements. This is not a marketing exercise — the mineral signature of high-altitude Nepalese Shilajit looks different from lowland or counterfeit material, and reviewing it is part of how we confirm the source.

Step 5

COA issued, batch labelled, jars sealed.

The independent laboratory issues a Certificate of Analysis for the batch, citing the lab name, batch ID, methodology and measured values. The batch ID is stamped on the jar label so a customer can request the specific COA tied to their product.

COA available on request for retail jars

You will need

· Slow water-purified Shilajit resin (batch sample)
· Sealed transport container
· Independent laboratory assay

Collect representative sample
After slow purification in Kathmandu, a representative sample is drawn from the batch and sealed.
Fulvic and humic acid assay
Independent laboratory assays fulvic acid (target ≥ 60%) and humic acid (target ≥ 25%) against reference standards.
ICP-MS heavy-metal screen
Lead, cadmium, arsenic and mercury quantified via ICP-MS against safe-consumption thresholds.
Full mineral profile
Iron, magnesium, zinc, copper, selenium and other trace elements quantified to verify the high-altitude mineral signature.
Issue COA, stamp batch, seal jars
Lab issues the Certificate of Analysis. Batch ID is printed on each jar. Tamper-evident jars are filled and dispatched.
