Pesticide and Heavy Metals Testing for Chinese Herbs
Every outgoing Chinese herbal batch is tested before release, with the applicable pesticide-residue and heavy-metal results recorded in the batch-specific COA. Acceptance limits are confirmed according to the product and destination market.
What Pesticide and Heavy Metals Testing for Chinese Herbs Covers
Every outgoing batch undergoes the applicable pesticide-residue and heavy-metal release testing before approval — nothing ships on a spot-check.
Heavy Metals — by ICP-MS
Lead (Pb) · Cadmium (Cd) · Arsenic (As) · Mercury (Hg), measured down to trace levels.
Pesticide Residues — by GC-MS / LC-MS
Organochlorine, organophosphate and pyrethroid screens.
Safety & Routine Tests
Aflatoxins · Microbial limits · Sulfur dioxide residue · Moisture · Ash · Purity.
Tested Against Your Market’s Limits
| Market | We Align To |
| United States | FDA / USP contaminant limits |
| European Union | EU pesticide MRLs & heavy-metal limits |
| Japan | Positive List system |
“Tested” means nothing if it’s not tested against the limit you actually ship to.

Why Pesticide and Heavy Metals Testing Matters
The two risks come from different places, and you can’t see either one:
Facility Laboratory and Third-Party Testing Options
Yes. Every outgoing Chinese herbal batch is tested before release, with the applicable pesticide-residue and heavy-metal results recorded in the batch-specific Certificate of Analysis
A Report for Every Batch
Every batch ships with a Certificate of Analysis covering its pesticide and heavy-metal results, tied to that specific lot and traceable to its source. Need a sample report before you order? Just ask.
Pesticide and Heavy Metals Testing — FAQ
Q: Are Chinese herbs tested for pesticides and heavy metals before export?
A: At Aile Herb, every batch is screened for pesticide residues by GC-MS and LC-MS and for heavy metals by ICP-MS before release, with the results recorded on the batch’s Certificate of Analysis.
Q: Which heavy metals do you test for?
A: We test for lead, cadmium, arsenic and mercury using ICP-MS, which detects these metals down to trace levels, and we check each batch against the limits for your destination market.
Q: Why does this testing matter for Chinese herbs?
A: Herbs absorb metals from soil and water as they grow, and pesticides can remain from cultivation — neither is visible. Testing every batch is the only way to confirm a lot is within safe limits before it reaches your facility.
Q: Do you test every batch?
A: Yes. Every outgoing Chinese herbal batch is tested before release, with the applicable pesticide-residue and heavy-metal results recorded in the batch-specific Certificate of Analysis.
Source Herbs That Pass Inspection the First Time
Each confirmed batch is reviewed before it leaves the production facility. The pesticide and heavy metals testing scope, COA parameters and destination-market requirements should be agreed before the order enters production.
