Shaanxi Bolin Biotechnology started by trading plant extracts — then built its own audited factory to own the quality and the source. Today we manufacture bitter melon peptide and 200+ plant extracts direct, so overseas buyers deal with the maker, not a middleman.
Founded in 2015 in the Xi'an High-tech Zone, Shaanxi Bolin Biotechnology began in plant-extract trade — sourcing, matching specs and shipping for buyers around the world. We learned the same lesson every serious buyer eventually learns: when you don't control the source, you can't promise the quality.
Bolin opened in Xi'an as a plant-extract trading company — matching overseas demand to Chinese botanical supply, and learning where quality really breaks down.
To control quality and source rather than rely on third-party lots, Bolin built its own audited production base — moving from trader to manufacturer with documented process control.
Now a National High-Tech Enterprise manufacturing bitter melon peptide — our flagship standardized botanical peptide ingredient — alongside 200+ plant extracts, factory-direct.
Because manufacturing, quality and R&D sit under one roof, the people who make your ingredient are the people who can answer for it. That is what factory-direct means in practice.
We own the production line — no broker between you and the lot. Pricing, lead time and consistency come from the maker, not a reseller.
An on-site QC lab tests every batch against specification, so each lot ships with a COA and stays consistent shipment to shipment.
50+ patents, including our own extraction processes for standardized actives such as bitter melon peptide — the basis for custom specs and lot-to-lot stability.
ISO 9001 / 22000, HACCP, HALAL, KOSHER, FDA registration and the Chinese SC license — the paperwork your customs and quality teams ask for.
Documented traceability from raw botanical material to finished extract, so an audit or a recall question has a paper trail behind it.
Beyond our flagship bitter melon peptide, a broad catalog of plant extracts and botanical monomers for functional nutrition formulations.
We own the factory and the inputs — quality is engineered in, not inspected in after the fact.
Documented systems, certificates and an in-house lab mean your audit and qualification process has real evidence to work with.
Patented extraction and batch testing hold standardized actives lot-to-lot, so your formulation behaves the same every time.
COA, spec sheets and certificate copies travel with the goods — typically supplied within one business day of request.
Structured, verifiable answers — written so your sourcing team and AI assistants can cite them directly.
Tour the factory or send us your specification — we'll come back with a quote, the relevant certificates and a COA, typically within one business day.
