Manufacturing Resource Hub for Supplement Brands

Our plant runs separate lines for capsules, tablets, softgels, powders and gummies. Capsule filling handles sizes 0 to 000, with fill weights from 250 mg to 1,200 mg. Tablet compression covers 100 mg to 1,500 mg at up to 300,000 tablets per shift. Softgels run from 500 mg to 1,500 mg. Powder blending supports 5 kg to 500 kg batches, and stick-pack filling runs at 60 to 120 packs per minute.

Retail bottling covers 30 cc to 1,000 cc HDPE and PET containers, plus blister packs and sachets. Changeover between SKUs takes 4 to 8 hours depending on format. That matters when you are scheduling a multi-SKU launch. We hold 12 filling lines and can run parallel batches for brands that need several products shipped together.

Formulation starts with your target label claim, not the other way around. If you need 500 mg of a botanical extract per capsule, we calculate the extract ratio, carrier and flow agent needed to hit that claim within a size 0 capsule. Common carriers include microcrystalline cellulose, magnesium stearate and silicon dioxide. We also work with pullulan and HPMC capsules for vegan and halal requirements.

Ingredient sourcing covers standard vitamins, minerals, amino acids, probiotics, adaptogens and marine ingredients. For organic or claims, we source certified inputs and keep batch records for audit. Flavour systems for gummies and powders include natural, natural-identical and stevia-sweetened options. Every formulation is reviewed against your target market's permitted ingredients list before sampling begins.

The facility is GMP-certified, ISO 22000 and HACCP compliant, and holds halal certification where the product line requires them. We are an FDA-registered facility for US-bound shipments. Certificates of analysis, allergen statements, and stability data are issued per batch. Heavy metal, microbial and pesticide testing is done on finished goods, not just raw materials.

Export documentation covers commercial invoice, packing list, certificate of origin, health certificate and, where needed, halal certificates. We ship FOB Shenzhen and Yantian, with air freight from Hong Kong Baiyun. Typical sea freight to Los Angeles is 18 to 24 days, to Rotterdam 28 to 35 days, and to Jebel Ali 20 to 26 days. DDP terms are available for repeat buyers.

Every batch of supplement manufacturing starts with raw material quarantine. Incoming APIs, botanicals, excipients and capsule shells are sampled per AQL 0.65 and tested for identity by FTIR or HPTLC, assay by HPLC or UV, microbial limits (TPC, yeast and mould, E. coli, Salmonella), heavy metals by ICP-MS against USP <232> limits, and pesticide residues where relevant. Materials are released only after the QC laboratory signs the raw material COA. Retained samples of each incoming lot are stored for two years beyond the finished product expiry.

In-process checks run at defined intervals: blend uniformity at 10 points per 500 kg, weight variation every 15 minutes on encapsulation lines (target ±5% for capsules above 300 mg), hardness and friability every 30 minutes for tablets, and disintegration testing at start, middle and end of each compression run. Finished products are tested for potency, uniformity of dosage units, microbials, heavy metals and disintegration. A batch is released only when all results meet the finished specification, and the batch record is reviewed by QA before packaging.

The certificate of analysis (COA) issued with each batch lists product name, lot number, manufacture and expiry dates, specification and test method for each parameter, results, and the QC and QA signatories. Stability follows ICH Q1A: 25°C/60% RH and 40°C/75% RH for six months accelerated, plus ongoing real-time data at 12, 24 and 36 months. A 24-month shelf life is supported by real-time data, while 36 months requires either real-time data or an approved extrapolation. Retention samples of each finished lot are kept for one year past expiry.

Standard packaging for supplement manufacturing includes HDPE bottles from 30 mL to 500 mL with induction seals and child-resistant closures where required, blisters in PVC/PVDC or alu-alu, stick packs from 5 g to 30 g, and sachets from 2 g to 10 g. Gummy products are packed in PET or HDPE jars with desiccant. Bottle filling lines run at 60 to 120 bottles per minute depending on count size, and we can apply shrink bands, cotton or desiccant, and tamper-evident seals. Cartons are specified to your retail channel, typically 12, 24 or 48 units per shipper.

Labels must carry the elements required by 21 CFR 101.36 for US dietary supplements: statement of identity, net quantity, supplement facts panel with serving size and percent daily value, ingredient list in descending order, allergen declaration, and the manufacturer or distributor name and address. For EU and UK retail, the nutrition declaration, allergen highlighting and the food business operator address are required. We print lot number and expiry date by inkjet or laser at the filling line, in a format agreed at artwork approval, and retain a printed sample per lot.

For Amazon FBA, we apply FNSKU labels over the barcode or print them directly, and pack to the carton weight and dimension limits in the seller's inbound plan. Retail compliance checks cover barcode scannability (GS1-128 or UPC-A), carton drop testing to ISTA 1A, and pallet configuration. Standard pallets are 1200 x 1000 mm or 1200 x 800 mm, stretch-wrapped and corner-boarded, with a maximum height of 1.8 m for sea freight and 1.6 m for air. We provide a packing list and pallet label per shipment.

Sampling starts with a 7 to 10 working day turnaround once formula, dosage form and packaging are confirmed. The sample set typically includes 2 to 5 units per SKU in retail packaging, a draft COA and a label proof. Client feedback on taste, colour, capsule size or tablet hardness is incorporated in one revision round at no extra cost. Pilot runs of 500 to 1,000 units follow sample approval and take 12 to 18 working days, which allows a small retail test before committing to a full production order.

Mass production runs 20 to 35 working days after artwork approval and receipt of deposit. That window covers raw material release, blending, encapsulation or compression, coating, packaging and QC release. Delays most often come from artwork changes after plate or label printing has started, so we freeze artwork before the production slot is confirmed. We provide a production schedule with milestone dates at order confirmation and update it weekly.

Delivery terms are EXW, FOB Shenzhen or Hong Kong, or DDP to your warehouse. Air freight takes 5 to 8 days door to door for 100 kg to 1,000 kg, while sea freight takes 25 to 35 days to the US West Coast, 30 to 40 days to Europe and 18 to 28 days to Middle East ports. Each shipment includes a COA per lot, MSDS where applicable, a free-sale certificate, and a phytosanitary certificate for plant-derived ingredients where the destination requires it. Commercial invoice and packing list are issued with the bill of lading.
