Who we are
Konjac Bio Limited is a sourcing and trading company based in Shanghai, China (Reception, Floor 3, Building 5, 657 Guangzhong Road). We do not operate a factory. We work with vetted producing factories in China's konjac-growing regions — Yunnan, Hubei, Sichuan, Guizhou and Shaanxi — and manage sourcing, quality checks and export paperwork on the buyer's behalf. We visit and vet each producing factory before adding it to our supplier base, and we re-check factories periodically as orders continue.
For a wholesale buyer, this means one point of contact instead of negotiating separately with several factories, one consolidated shipment across multiple product categories, and factory-issued documents (specification sheets, COAs, and certificates on request) passed through to you exactly as the producing factory issues them.

How ordering works
Most wholesale orders move through the same six steps, whether you are buying a single product or several from the range at once.
- 1. Inquiry — you tell us the product, grade or format, volume and destination.
- 2. Spec confirmation — we confirm specification, packaging and pricing with the producing factory.
- 3. Sample — a sample is prepared and shipped by courier; timing is confirmed when the sample is arranged.
- 4. Proforma invoice — once the sample is approved, we issue a proforma invoice (PI) for deposit, with lead time confirmed on the PI.
- 5. Production and consolidation — the producing factory manufactures the order; if you are ordering more than one product, we consolidate shipments at a single point before export.
- 6. Export — pre-shipment documents are issued and the order ships FOB Shanghai or CIF to your port.
Documents we provide per shipment
Every shipment is issued with the following documents from the producing factory: specification sheet, Certificate of Analysis (COA), packing list, commercial invoice, and bill of lading.
Konjac Bio Limited holds no certificates of its own. Certificates such as food safety system certification, Kosher, Halal or similar are available on request from the producing factory, per lot, where the factory holds them — confirm which certificates you need before placing an order so we can check with the relevant factory.

Samples, payment and shipping
Small samples are available before you commit to an order — powder samples or a few units of finished goods. The buyer pays courier cost.
Payment is by T/T; terms are stated on the proforma invoice. Shipping terms are FOB Shanghai or CIF to your destination port as standard, with EXW and DAP available on request.
If you order more than one product from the range above, we can consolidate them into a single container to reduce freight cost per unit.
