Our own factory.
Source control.
From trader to our own production line — Bolin self-manufactures bitter melon peptide and 200+ plant extracts, so the auditability, consistency and compliance overseas buyers demand stay in our hands, not a middleman's.
The difference between buying from a trader and buying from the maker.
Most overseas buyers of plant extracts get a trader between them and the plant — which means no audit access, no batch traceability, and a margin stacked on top. Bolin closed that gap by building its own factory.
- No access to the production floor
- Batch source changes silently
- COA you can't trace to a line
- Middleman margin on every kg
- "We'll check with the factory"
- On-site & remote audits welcome
- Batch-level traceability to the line
- COA tied to our own production
- No middleman markup
- Fast technical answers
What the factory gives your supply chain.
In-house extraction
Our own extraction and refining lines for peptides, sterols, botanical monomers and powders — patented, water-based where possible, no outsourced production.
On-site QC lab
Identity, purity and contaminant testing in-house — each lot released against spec before it ships, with COA tied to the batch.
Audit-ready records
Traceable raw-material sourcing and batch records, built for buyer audits, third-party certification and regulatory dossiers.
Export-compliant
HALAL / KOSHER certified, FDA registration, SC license + export-food-producer filing (SGS inspection reports available) — shipping to the US, EU, Middle East and SE-Asia.
Standardized actives
Patented processes hold actives lot-to-lot (e.g. bitter melon peptide at 75% / 85%), so your formulation behaves the same every order.
R&D & custom specs
National High-Tech Enterprise with 50+ patents — custom purities, particle sizes and documentation on request.
Five controlled steps, all under one roof.
Raw material
Traceable botanical sourcing with incoming identity checks.
Extraction
Patented, mostly water-based extraction of the target active.
Standardize
Refined and standardized to spec (e.g. 75% / 85%).
QC release
In-house lab tests purity & contaminants; COA issued per lot.
Pack & ship
Food-grade packaging, export docs, dispatch worldwide.
