Berberine: Compliance Issues for B-End Purchasers

Table of Content [Hide]

Berberine Compliance Summary: Dual Supervision by Pharmaceutical and Food Regulations

It is divided into plant extract (dietary supplement) and hydrochloride (pharmaceutical grade). The key compliance points are distinguishing product forms and avoiding medical efficacy claims. Internationally, dietary supplements shall meet GRAS (US) and THR (EU) requirements; pharmaceutical grade requires GMP and DMF/CEP certification. In China, berberine hydrochloride is defined as a pharmaceutical product requiring drug production qualifications, while berberine plant extract can be used as dietary supplement raw material. Suppliers shall provide grade-specific qualifications as well as pesticide residue and heavy metal test reports. Labels shall bear compliance reminders with medical claims strictly prohibited. Contracts shall specify product form, claim restrictions and liability for non-compliance.

1. International Regulatory Access

EU: As dietary supplement raw material, no explicit EFSA approval required but compliant under Traditional Herbal Registration (THR); pharmaceutical grade requires CEP/GMP.
US FDA: Regulated as dietary supplement under DSHEA with GRAS recognition (Generally Recognized As Safe); medical treatment claims are prohibited; pharmaceutical API requires DMF/GMP.
China: Berberine hydrochloride is a pharmaceutical product (Berberine Tablet), and its API is regulated under pharmaceutical supervision (GMP, Production License); non-hydrochloride berberine plant extract can be used as dietary supplement raw material.
Promotion Red Line: Global prohibition of claiming as pharmaceutical products; dietary supplements can only be labeled with supporting metabolism / blood sugar health.

2. Mandatory Supplier Qualification Verification

Plant Extract Grade (Dietary Supplement): Business License (plant extract / food raw material), ISO 22000, FSSC 22000, HALAL/KOSHER, pesticide residue / heavy metal test report.
Pharmaceutical Grade (Berberine Hydrochloride): Drug Production License, GMP, Chinese Pharmacopoeia/USP/EP grade COA (≥97%), DMF/CEP.
General Documents: COA (purity, related substances, pesticide residues, heavy metals, microorganisms), MSDS, botanical origin identification report.

3. Packaging, Labeling and Transportation

Packaging: 25kg cardboard drum / 1kg aluminum foil bag, sealed, light-proof and moisture-proof, stored at room temperature.
Labeling: Bilingual labeling including product name, CAS number, batch number, purity, botanical origin, production date, validity period and storage conditions; pharmaceutical grade marked with API, not for direct use; dietary supplement grade marked with Non-pharmaceutical, no therapeutic effect.
Transportation: General chemical/food raw materials, light-proof, moisture-proof and high-temperature avoidance; cold chain is not required.

4. Restriction & Risk Control

Ingredient Classification: Berberine hydrochloride = pharmaceutical product; free berberine extract = dietary supplement; mixed declaration is strictly prohibited.
Pesticide Residue / Heavy Metal: Pesticide residue ＜0.05mg/kg, Pb＜10ppm, As＜2ppm, Hg＜1ppm.
Microorganisms: Total bacterial count ＜1000cfu/g, mold ＜100cfu/g, no pathogenic bacteria detected.
Claim Compliance: Medical claims such as treating diarrhea/enteritis/lowering blood sugar are absolutely prohibited.

5. Contract and Traceability

Clarify product form (extract/hydrochloride), purity standard, botanical origin, claim restrictions and batch traceability.
Agree on liability division, recall and compensation for violations confirmed by customs or drug regulatory authorities.
