Berberine Capsule Manufacturer for Retail-Ready SKUs

The plant runs two encapsulating lines with a combined capacity of 120,000 capsules per hour, plus a third line reserved for small batches. Berberine blends are processed in a 300 kg ribbon mixer under 35% relative humidity to limit caking. Standard fill weights are 250 mg, 300 mg, 500 mg, 600 mg and 1,000 mg, with a fill tolerance of ±3% for 500 mg and above. Larger capsules use size 00; smaller doses use size 0.

Batch sizes start at 1,000 units for pilot runs and scale to 500,000 units per SKU. Changeover between berberine and other botanical actives follows a validated cleaning protocol with swab testing for cross-contamination. If you need a second SKU — for example 500 mg plus a 1,000 mg version — both can run in the same production window to reduce lead time.

Berberine HCl is bitter and hygroscopic. Most retail formats use 97% berberine HCl, but we also handle 5:1, 10:1 and 20:1 extracts, and berberine sulfate where a lower chloride load is preferred. Excipients are kept minimal: magnesium stearate at 1–2%, silicon dioxide at 0.5–1% as a flow agent, and microcrystalline cellulose for fill weight adjustment. No titanium dioxide is used in HPMC shells.

Opaque shells are standard because berberine degrades under UV light. We can also add a cellulose-based enteric coating for release profiles, though this increases lead time by 5–7 days. Common co-ingredients include chromium picolinate, cinnamon extract, bitter melon and alpha-lipoic acid. Blends are tested for uniformity at three points in the batch, and assay results are provided before encapsulation.

Every batch is tested for assay, heavy metals, microbial limits and residual solvents. Certificates of analysis are issued per batch, and stability data is available for 24 months at 25°C/60% RH and 6 months at 40°C/75% RH. The facility is GMP-certified, ISO 22000 and HACCP compliant. Halal and certifications are held for relevant materials, and vegan HPMC shells are available.

For US-bound orders, we provide FDA-registered facility documentation and prior notice support. EU orders include a food safety declaration and allergen statement. Middle East shipments can be halal-certified with Arabic labelling. Shipping is by air or sea from Shenzhen or Hong Kong; air freight for 10,000 units takes 5–8 days to the US East Coast, sea freight 18–25 days. Labelling can be printed and applied in-house.

Each berberine capsule batch is tested at three stages: incoming raw material, in-process blend, and finished capsules. Raw berberine HCl or extract is sampled per lot for identity by HPLC or TLC, potency assay, microbial limits (total aerobic count, yeast and mould, E. coli, Salmonella), heavy metals (lead, arsenic, cadmium, mercury) and residual solvents where applicable. In-process checks cover blend uniformity and moisture content. Finished capsules are tested for disintegration, weight variation and potency to confirm label claim.

The certificate of analysis (COA) issued with each batch lists the product name, lot number, manufacture and expiry dates, specifications, test methods and results. It is signed by the QC manager and references the retained sample. Retention samples of every batch are stored under labelled conditions for at least two years beyond expiry, allowing re-testing if a customer query arises. Stability testing follows an accelerated protocol at 40°C/75% RH for six months, with real-time data at 25°C/60% RH for up to 24 months to support the assigned shelf life.

Berberine capsules can be packed in HDPE bottles with induction seals, blister packs (PVC/PVDC or alu-alu), stick packs or sachets. Bottle sizes typically range from 60 to 180 counts, with desiccant options for hygroscopic fills. Blister and stick formats suit unit-dose or travel retail. Cartons are specified with lot number, expiry date and, where required, a GTIN. We can apply FDA dietary-supplement label elements including the supplement facts panel, ingredient list, allergen statement and 'Keep out of reach of children' warning, subject to your approved artwork.

Lot and expiry coding is applied by inkjet or laser on the primary container and outer carton. Cartons are packed in corrugated shippers with a maximum gross weight of 20 kg for manual handling, or 25 kg where palletised. Standard pallet footprints are 1200 x 1000 mm or 1200 x 800 mm, stretch-wrapped and labelled with SSCC if needed. For Amazon FNSKU and retail compliance, we can print and apply FNSKU labels, poly-bag units with suffocation warnings, and prepare cartons to your marketplace's inbound requirements.

Sampling starts with a 7–10 working day turnaround for a pilot batch of 1,000 units, which allows you to confirm fill weight, shell type and packaging. Mass production runs 20–35 working days after sample approval, depending on capsule size, fill weight and packaging format. MOQ is 1,000 units per SKU, with lower pilot quantities available for market testing. Scheduling is confirmed once artwork and specifications are signed off.

Delivery can be arranged by air or sea. Air freight typically takes 5–8 days door to door for urgent launches, while sea freight takes 25–40 days depending on destination port. We quote EXW, FOB or DDP terms; DDP is available for selected markets and includes customs clearance and duty. Shipping documents provided include COA, MSDS, free-sale certificate and, where relevant, phytosanitary certificate for plant-derived ingredients. Commercial invoice, packing list and bill of lading or airway bill are issued per shipment.
