Pesticide And Heavy Metals Testing for Chinese Herbs
Pesticide and heavy metals testing for Chinese herbs is the test most suppliers skip — or quietly outsource. We run it in-house, on every batch, screening for lead, cadmium, arsenic, mercury and pesticide residues, and we hand you the numbers.
What Our Pesticide And Heavy Metals Testing Covers
Every batch goes through the same panel before it’s released — 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.
Tell us your destination market and target spec, and we set the test scope before we quote.
Why Pesticide and Heavy Metals Testing Matters
The two risks come from different places, and you can’t see either one:
Tested In-House, Not Outsourced
Trading companies send samples to an outside lab and forward whatever comes back. We test in our own laboratory — Shimadzu HPLC, ICP-MS and GC-MS, staffed by 12 QC inspectors. For you that means three things: faster turnaround, because samples don’t wait in a queue; full test scope, because we’re not paying a third lab per test; and data we own and can explain, line by line, when your QA team asks.
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.
Source Herbs That Pass Inspection the First Time
A failed lab result means a held shipment, a rejected lot, and a customer who waits. Every batch leaves our factory only after it’s tested in-house — so the COA in your hands matches what arrives at your dock.
