Private Label Resource Hub for Supplement Brands

The plant runs separate lines for capsules, tablets, softgels, powders and gummies, with a combined output of 2.5 million units per day across two shifts. Capsule filling handles size 0 to 3, with fill weights from 250 mg to 800 mg. Tablet compression covers 500 mg to 1,500 mg, including coated and sustained-release options. Powder blending runs 100 kg to 1,000 kg batches, filled into jars, pouches or stick packs. Softgels suit oil-based actives and are produced on a 60,000-per-hour line.

For brands planning a range, the practical constraint is usually MOQ rather than capacity. Retail bottling starts at 1,000 units per SKU. Pilot runs of 1,000 units are possible on selected formats when the formula uses stock ingredients. Multi-SKU orders can share a production window, which shortens the total timeline and reduces changeover cost. A typical three-SKU launch moves from sample approval to shipped goods in 20-35 working days.

Formulation support covers standard blends and custom actives. The team works from a customer brief or a reference product, then adjusts for dosage, taste, flow and stability. Common inputs include vitamins, minerals, botanicals, amino acids, probiotics and omega-3 oils. Ingredient documentation follows EU and US expectations: certificates of analysis, allergen statements, non-GMO declarations and country-of-origin records. Where a branded ingredient is required, the plant can source it under a non-disclosure agreement.

Ingredient lead time varies. Stock vitamins and minerals add no delay. Specialty botanicals, probiotic strains and organic-certified inputs can add 5-15 working days to the sample stage. For or vegan claims, the full supply chain must be documented, so early confirmation matters. Excipient choices also affect the label: magnesium stearate, silicon dioxide and cellulose are common, and clean-label alternatives are available at a modest cost increase. Halal certification applies to both the formula and the capsule shell.

Quality control runs at three points: incoming raw material, in-process checks and finished goods. Each batch is tested for identity, potency, microbial limits and heavy metals. Retain samples are held for two years. The facility is GMP-certified, ISO 22000 and HACCP compliant, and registered with the FDA. Halal and vegan certifications are maintained where the product line requires them. Documentation packs include COA, MSDS, flow chart and shelf-life data.

Shipping terms are FOB Shenzhen or Yantian, with air and sea options. A 20-foot container holds roughly 12-15 pallets, depending on carton size. Standard retail cartons are 24 or 48 units. Labels can be applied in-house, or supplied by the brand for application on the line. For EU and UK buyers, the plant provides the technical file inputs needed for a responsible person. For Middle East buyers, halal certificates and Arabic labelling support are available. Typical door-to-door sea transit to Rotterdam is 28-35 days.

Every private label batch is tested against a written specification before release. Raw materials are sampled on receipt and screened for identity by FTIR or HPLC, with potency assayed against the certificate of analysis from the ingredient supplier. During production, in-process checks cover weight variation, hardness for tablets, and fill weight for capsules at intervals of no more than 30 minutes. Finished goods are then tested for potency, microbial limits (total aerobic count, yeast and mould, E. coli, Salmonella), heavy metals (lead, arsenic, cadmium, mercury) and disintegration time. Disintegration is typically 15 minutes or less for capsules and 30 minutes or less for tablets, depending on the monograph.

A certificate of analysis accompanies each batch and lists the product name, batch number, manufacturing date, expiry date, tests performed, specification limits and results. It also names the analytical methods used and carries a signed release by the quality control manager. Where a customer needs third-party verification, samples can be sent to an external laboratory and the report attached to the COA. Retention samples of every batch are kept for the full shelf life plus six months, stored under labelled conditions. Stability is monitored through accelerated studies at 40°C and 75% relative humidity for six months, with real-time data at 25°C and 60% relative humidity for products with a two-year claim.

Deviations are documented and investigated before release, and a batch is not shipped until the quality unit signs off. For private label customers, the batch record and COA are shared as part of the order documentation. If a customer requires a specific microbial limit or a narrower heavy-metal threshold, this is written into the specification before the first production run so that testing and release criteria match the target market.

Packaging options cover high-density polyethylene bottles from 30 ml to 500 ml, blister packs, stick packs, sachets and gusseted pouches. Bottles can be supplied with induction seals, child-resistant closures and desiccant sachets where required. For stick packs and sachets, fill weights range from 2 g to 30 g, with three-side or four-side seals. Labelling follows the destination market: for the US, the FDA dietary supplement label requires a statement of identity, net quantity of contents, supplement facts panel, ingredient list, allergen declaration where applicable, and the manufacturer or distributor name and address. We print lot numbers and expiry dates by inkjet or laser, with the format agreed at artwork approval.

Carton and pallet specifications are confirmed before production. Standard export cartons are double-wall corrugated, with a maximum gross weight of 20 kg, and pallets are 1,200 x 1,000 mm or 1,200 x 800 mm depending on the market, stretch-wrapped and labelled with batch, quantity and handling symbols. For Amazon sellers, we can apply FNSKU labels and poly-bag units according to the marketplace requirements, but the seller remains responsible for confirming the final label content with Amazon. Retail-ready packaging, such as shelf-ready trays or display cartons, is available on request and adds 5 to 10 working days to the schedule.

The sample process starts with a formula brief and target dosage form. Once the formula is agreed, a sample is produced in 7 to 10 working days, including a preliminary COA. Sample costs are quoted per project and are typically credited against the first mass-production order. After sample sign-off, mass production takes 20 to 35 working days depending on format and packaging complexity. Capsules and tablets are at the shorter end; gummies and liquids need additional set-up and hold time. A deposit of 30 to 50 per cent is required to schedule production, with the balance due before shipment.

Shipping terms are quoted as EXW, FOB Shenzhen or Hong Kong, or DDP to the destination address. Air freight takes 5 to 10 days door to door and suits pilot runs or urgent replenishment; sea freight takes 25 to 40 days depending on the port and is more economical for full containers. For LCL shipments, we consolidate at the forwarder's warehouse and provide a packing list with carton dimensions and weights. Documents provided with each shipment include the commercial invoice, packing list, certificate of analysis, material safety data sheet where relevant, and a free-sale certificate. Phytosanitary certificates are arranged when a product contains botanical ingredients that the destination country regulates.
