Baisifu Weight Management

Quality & Compliance

Q: Do you support OEM and private-label documentation?

Yes. For finished formulas such as stick packs, capsules and gummies, we supply the documentation set under your brand.

Every batch of Baisifu plant extracts and finished formulas is released with an active-component assay performed by HPLC or UV spectrophotometry, full CAS-number traceability, and a complete documentation dossier: Certificate of Analysis (COA), Material Safety Data Sheet (MSDS) and Technical Data Sheet (TDS). Quality control does not stop at the marker compound — identity, purity and safety are verified on every single lot, before it leaves our facility.

What Every Batch Is Tested For

Production at our Xi’an facility runs under GMP and HACCP food-safety management. Each lot passes a four-panel release program before a COA can be issued:

Active-Component Assay (HPLC / UV)

Marker compounds are quantified by high-performance liquid chromatography or UV spectrophotometry against reference standards, guaranteeing the fixed active-content grade stated on the label — batch after batch.

Heavy Metals (Pb, As, Cd, Hg)

Lead, arsenic, cadmium and mercury are controlled on every lot against food-supplement and food-additive limits, with numerical results reported on the COA.

Solvent Residues

Residual solvents are screened per lot. Purified water and food-grade ethanol are our default extraction media; no unapproved class-1 solvents are used anywhere in the process.

Microbiological Control

Total plate count (TVC), yeast and mold, Escherichia coli, Salmonella, and Staphylococcus aureus are tested on every lot, with results stated directly on the COA.

Standardized Extract Grades, Backed by HPLC Certificates

Baisifu specializes in standardized botanical extracts with fixed active-content grades. Because every production run is assayed, the grade you qualify with is the grade you receive — sample and production lots are never blended to hit a specification. Typical fixed grades include:

Extract	Marker / Active	Fixed Grade	Assay Method
Garcinia Cambogia Extract	Hydroxycitric acid (HCA)	60%	HPLC
Green Coffee Bean Extract	Chlorogenic acid	50%	HPLC
L-Carnitine	L-Carnitine base / L-tartrate	98% / 99%	HPLC
Green Tea Extract	EGCG	50%	HPLC
Synephrine (Citrus aurantium)	Synephrine HCl	6% or 30%	HPLC
Grape Seed / Pine Bark	Proanthocyanidins (OPC)	95%	UV
Haematococcus Pluvialis	Astaxanthin	5%	HPLC
White Kidney Bean Extract	Phaseolamin	1–3% / custom	UV
5-HTP (Griffonia seed)	L-5-Hydroxytryptophan	98%	HPLC
Fucoxanthin (Undaria)	Fucoxanthin	10% / custom	HPLC

Grades outside this list are developed on request — tell us the marker compound and target content, and our application lab will quote a standardized grade with the matching assay method.

The Documentation Dossier You Receive

Every shipment travels with a lot-specific document set, so your QA team can complete supplier qualification and regulatory filing without follow-up requests:

Document	Content	Issued
Certificate of Analysis (COA)	Lot number, assay result, heavy metals, solvent residues, microbiology, appearance, loss on drying, particle size	Per lot
Material Safety Data Sheet (MSDS)	GHS-aligned classification, handling, storage and transport information	Per product
Technical Data Sheet (TDS)	Specification table, recommended applications, dosage, shelf life, packaging	Per product
Traceability Statement	Botanical source, plant part, extraction medium and full CAS-number traceability	Per lot
Additional Statements	Allergen, GMO, BSE/TSE, non-irradiation and other compliance declarations	On request

From Botanical Identity to Released Powder

Raw-material identity. Incoming botanicals are verified for species, plant part and origin; marker fingerprints are confirmed before the material enters the extraction line.
In-process control. Extraction, concentration and drying parameters are logged under HACCP critical control points; intermediates are checked for moisture and marker content.
Finished-goods QC. The full four-panel program (assay, heavy metals, solvents, microbiology) is executed on the finished powder or liquid.
Release & retention. A COA is issued only after all results conform; retained samples from every lot are kept so any future question can be answered against the exact batch you received.

Frequently Asked Questions

Is the COA lot-specific or generic?

Every COA reports results for your exact lot number — assay, heavy metals, solvent residues and microbiology are measured on the batch you receive, not copied from a template.

Can you provide third-party test reports?

Yes. In addition to in-house QC, we can arrange re-testing of your lot at an independent laboratory and share the report before shipment, so you can verify results from a second source.

Do you support OEM and private-label documentation?

Yes. For finished formulas (stick packs, capsules, gummies), we supply the documentation set under your brand, including formula disclosure levels agreed in the supply agreement.

Which markets do your specifications target?

Specifications are written for dietary-supplement and functional-food use, with limit tables that can be aligned to EU, US or your local regulatory requirements on request.

How fast can documents be issued for an order?

The COA accompanies the shipment; pre-shipment copies of assay results can be shared with your QA team before goods leave the factory, and standing customers receive the full dossier electronically with each invoice.

Need a COA Sample Before You Qualify Us?

Tell us the extract, the grade and your target market — we will send a documentation pack with a recent lot-specific COA for your QA review.
