COA status
PublicView document
View COACOA document review notes
COA from Shenzhen ZTS Testing Service Co., Ltd (not a recognized accredited lab). Heavy metals (Lead/Arsenic/Mercury/Cadmium) are all reported as '0%', which is not a standard or credible way to report heavy metal test results (expected: ppm or ND/<LOQ). Left as PUBLIC since a document exists, but flagged as low-confidence.
Not disclosed
The testing laboratory is not publicly named for this product. Without a named lab, it is not possible to verify the independence or accreditation of any testing performed.
Status
Claimed — brand states testing was done; specific values not publicly available
The brand states that heavy metals have been tested, but the specific numeric results are not publicly available. This cannot be independently verified without seeing the actual COA values.
Heavy metals to look for in a shilajit COA: lead (Pb), arsenic (As), mercury (Hg), cadmium (Cd). A rigorous COA shows parts-per-million (ppm) values for each, not just a pass/fail stamp. Learn more about shilajit and heavy metals →

About this data
COA status is assessed based on publicly available documentation as of the last verified date shown on the product page. A certificate is marked “Public” only when it is directly accessible without needing to request it. Heavy metals are marked “Confirmed” only when the COA includes actual numeric concentrations. We do not independently audit laboratory accreditation for every entry.
