When a container of sweetener or snack leaves our Xiamen warehouse, it carries more than product — it carries a paper trail. 🔍 For a B2B buyer, that trail is often the difference between a smooth landing and a customs headache.
One Batch, One COA, Zero Surprises
Every production lot is tested before it is released. Moisture, dry solids, colour band and microbiology are checked against the spec before the drums are sealed, and the COA follows the goods all the way to your port. 📄 No “we will send it later” — the certificate ships with the batch.
| Parameter | Frequency | Requirement |
|---|---|---|
| Moisture | Checked per batch | Within spec band |
| Dry solids / brix | Checked per batch | ±0.5% of target |
| Microbiology | Per production day | EU / FDA limits |
| Retained sample | Every batch | Kept 24 months |
Why Traceability Matters for Importers
Buyers who insist on batch-level COAs recover faster from port inspections and avoid the “sample vs container” mismatch that plagues the industry. 🧾 Our retained samples are kept for two years, so a question asked in month eleven can still be answered.
Consistency is not glamorous. It is a hundred small checks repeated every shift. ✅ But it is exactly what repeat buyers mean when they say a supplier “feels reliable.”
👉 Tip for buyers: ask for the last three batches’ COAs before your first PO. If the numbers drift, you will see it before you commit.
Frequently Asked Questions
What is tested before a Liangdu batch is released?

Why do importers insist on batch-level COAs?
