Our standard MOQ is 1 kg for most extracts and 25 kg for bulk essential oils, depending on the product and specification. We support small trial orders so you can validate quality in your application before scaling up. For high-value or rare botanical actives, MOQ may be flexible — contact our sales team for a specific quotation.

Yes. We provide 20–50 g free samples for most products, shipped together with the complete COA. You only cover the courier cost (or provide your FedEx/DHL account number). Samples are dispatched within 48 hours of confirmation.

Send us your target products, specifications, and quantity via our contact form or email. We reply with a formal quotation including price, lead time, COA, and payment terms. Once the Proforma Invoice is confirmed and payment received, production and dispatch are scheduled immediately.

Every batch ships with a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS). Technical Data Sheets (TDS), HPLC/GC chromatograms, heavy-metal reports (ICP-MS), pesticide residue reports, and microbiological certificates are available on request — at no extra charge for confirmed orders.

All products are tested in our in-house laboratory equipped with HPLC, GC, UV-Vis, and ICP-MS instruments. For orders requiring independent verification, we can arrange testing through internationally accredited third-party labs (e.g., SGS, Eurofins) — the cost can be quoted separately or arranged under your account.

Our manufacturing operates under GMP guidelines and is certified to ISO 9001, ISO 22000, and HACCP. Kosher and Halal certifications are available for applicable product lines. Certificates can be downloaded or sent with any quotation.

Yes. We maintain a reference sample bank of 27,761 archived samples, and every raw material lot is fingerprinted (HPLC) before release. Production follows validated standard operating procedures, so each batch meets the same declared specification — typically within a tighter range than the label claims.

Samples ship within 48 hours. Standard bulk orders ship within 5–10 working days after payment confirmation. Custom specifications or large volumes (500 kg+) typically require 15–25 days. We confirm the exact schedule on every Proforma Invoice.

We ship worldwide via FedEx, DHL, UPS (air express, 5–8 days), air freight for larger volumes, and sea freight (LCL/FCL) for bulk orders. Hazardous-free botanical powders and oils are packed in fiber drums, aluminum foil bags, or as required. All exports include full customs documentation.

Yes. Our engineers can develop custom extract ratios, standardized marker levels, granulation, and blend formulations to your target specification. We also support private-label packaging with your branding. Share your requirements and we will return a development proposal with pricing and timeline.

Very likely. With direct access to cultivation bases across China’s botanical belt and a vetted supplier network, we routinely source and process herbs outside our standard 267+ product catalog. Send us the botanical name and target specification for a feasibility reply within one business day.

We accept T/T bank transfer (30% deposit + 70% against B/L copy for bulk orders; full prepayment for samples and small orders), PayPal for sample fees, and L/C at sight for established customers with orders above USD 20,000. Flexible terms can be discussed for long-term partners.

Absolutely. We regularly sign NDAs and supply agreements covering specifications, formulations, pricing, and private-label arrangements. Your commercial information stays strictly between us — it has been that way for every partner since 2008.
