Chinese Herbs Quality Control Process
The Chinese herbs quality control process covers incoming inspection, in-process checks, finished-product review, release testing and pre-shipment inspection. Every outgoing Chinese herbal batch is tested before release and issued with a batch-specific Certificate of Analysis.
Chinese Herbs Quality Control Process at Every Stage
For products supplied through Aile Herb, the Chinese herbs quality control process begins with incoming materials and continues through processing, finished-product testing, batch release and shipment review.
The result is simple: every batch is sampled, tested, documented and released against defined acceptance criteria, and every shipment carries its own Certificate of Analysis.

Five-Stage Chinese Herbs Quality Control Process
1
Incoming Raw Herb Inspection
Every batch of raw herbs is sampled and inspected on arrival — checked for identity, origin documentation, moisture, foreign matter, and visual quality before it is accepted into production.
2
In-Process Quality Control
During cutting, sorting, drying, and processing, our QC team monitors critical control points in line with GMP and HACCP requirements to keep every step within specification.
3
Finished Product Inspection
Finished herbal slices are tested against Chinese Pharmacopoeia (Ch.P. 2020) standards — including identity, active marker content by HPLC, moisture, ash, and appearance.
4
Release Testing & Documentation
Each outgoing Chinese herbal batch undergoes release testing before QA approval. The applicable test items and acceptance limits are confirmed according to the product and destination market.
5
Pre-Shipment Inspection
Before shipment, every batch is reviewed against acceptance criteria and released by QA. Export documentation and COA travel with the goods — and remote or third-party pre-shipment inspection can be arranged on request.
Inspection Standards & Acceptance Criteria
| Test Item | Method / Standard | Stage |
| Identity verification | Ch.P. 2020 / organoleptic + HPLC | Incoming + Finished |
| Active marker content | HPLC (Shimadzu) | Finished |
| Heavy metals (Pb, Cd, As, Hg) | ICP-MS | Release |
| Pesticide residues | GC-MS / LC-MS | Release |
| Microbial limits | Ch.P. / USP method | Release |
| Sulfur dioxide residue | Titration (sulfur-free standard) | Release |
| Moisture & ash | Gravimetric | Finished + Release |
Every outgoing batch undergoes release testing. The applicable test items, acceptance limits and any additional requirements are confirmed according to the product and destination market. to your destination market — US, EU, Japan, and others.
A Quality Management System You Can Audit
The Chinese herbs quality control process operates within the applicable quality-management and food-safety systems of the production facility. Relevant certificates, procedures and records can be reviewed during qualified-buyer verification.
Every Batch, Fully Traceable
Quality control and traceability work together. Each batch carries a unique code linked to its source warehouse, processing record and test results — so any finished product traces back to origin. If a question ever comes up about a lot, we don’t guess; we pull the code and follow it back. Complete batch documentation, including COA, ships with every order.
