Iron Gummy Manufacturer for Custom Dosing and Private Label

Our Guangdong plant runs depositing lines for pectin and gelatin gummies with a daily output of 1.2 to 1.8 million units depending on gummy weight and shape. Iron gummies are produced on dedicated runs to limit cross-contact with other actives. We control starch moulding, curing, demoulding and oiling in one continuous flow.

Each batch is weighed on calibrated scales, and iron premix is verified against the certificate of analysis before blending. We can produce two-piece or single-piece gummies, sugar-sanded or oil-coated, and fill into HDPE bottles, PET jars or blister packs. Bottle sizes range from 30 to 120 counts, with induction sealing and child-resistant caps for US and EU markets.

Iron salts carry metallic notes, and ferrous bisglycinate is often easier to mask than ferrous sulfate. We test each iron source at the target dose in a pectin base first, because pectin gels at lower temperatures and reduces degradation during depositing. Typical elemental iron doses are 5 mg, 10 mg, 14 mg and 18 mg per gummy, aligned with EU NRV and US label requirements.

Flavour systems use natural or nature-identical options. Common pairings are strawberry, orange, blackcurrant and mixed berry. We add vitamin C at 20-40 mg per gummy to support iron absorption and to act as an antioxidant. Colour matching uses fruit and vegetable concentrates or approved synthetic lakes. Each formula is stability-tested at 25°C/60% RH and 40°C/75% RH for 3 and 6 months.

Every iron gummy batch is tested for elemental iron content by ICP-MS or AAS, plus micro, heavy metals, and disintegration. We retain samples for 24 months. The facility is GMP-certified and holds ISO 22000 and HACCP. For halal claims, we source gelatin and processing aids from certified suppliers and schedule dedicated runs.

Export paperwork includes certificate of analysis, certificate of free sale, GMP certificate, halal certificates where applicable, and MSDS. We ship FOB Shenzhen or Yantian, with air freight for samples. Lead times for mass production are 20-35 working days after sample sign-off, and we provide a production schedule with weekly updates.

Every iron gummy batch is sampled at three points: after syrup preparation, at the depositor, and from the packed finished goods. The in-process sample confirms the iron salt has dispersed evenly before gelling, since ferrous salts settle faster than the pectin or gelatin matrix can hold them. Finished-goods testing then covers iron identity and potency by ICP-OES or titration, total plate count, yeast and mould, E. coli and Salmonella, lead, arsenic, cadmium and mercury, and disintegration time against the pharmacopoeial method your market requires. Potency results are reported as elemental iron, not as the salt weight, so your label claim can be set without conversion guesswork.

Batch records are compiled before release and include the master formula, actual weighed quantities, depositing temperature and humidity logs, curing room conditions, and the operator and line used. A certificate of analysis is issued per batch and states the specification, the test method, the result and the pass or fail decision for each parameter, plus the batch number, production date and expiry date. Where a customer needs a specific method, such as a client-supplied HPLC or ICP method, we run it alongside our in-house method and report both.

Retention samples of every batch are held for the full shelf life plus six months, stored in the same bottle and closure as the commercial pack. These are pulled at the stability checkpoints and at any complaint investigation. The stability protocol typically runs at 25°C and 60% relative humidity for 24 months, with accelerated conditions at 40°C and 75% relative humidity for six months, checking potency, colour, texture, moisture and microbial status. Iron oxidation shows first as colour shift and off-note, so sensory checks sit alongside the analytical ones.

Deviation handling is documented rather than verbal. If a batch falls outside the potency window, the record shows the root cause, the disposition decision and any corrective action on the depositing or curing step. Customers receive the deviation report with the certificate of analysis when a batch is affected, so the brand owner is never surprised by a result after goods have shipped. This is the level of traceability a contract iron gummy manufacturer needs to provide for retail and marketplace audits.

Standard retail formats are HDPE or PET bottles from 60 to 180 count with induction seal and child-resistant or standard closure, single-serve stick packs, and aluminium sachets. Gummies are hygroscopic and iron salts can promote moisture uptake, so we specify a desiccant where the stability data supports it and confirm the closure torque on the filling line. Blister is possible for gummies but less common because of the pack depth. Bottle fill is checked by count and by weight, and the label panel is applied after the lot code is printed, not before.

For the US market the label must carry the supplement facts panel with the iron amount per serving as a percentage of daily value, the serving size in gummies, the complete ingredient list in descending order, allergen statements where applicable, and the manufacturer or distributor address with a contact. Structure-function claims are the brand owner's responsibility and must comply with FDA rules. We print the lot number and best-by date in a legible format on the bottle and the carton, and we can apply Amazon FNSKU labels, retail shelf labels or a customer-supplied barcode at the line.

Carton and pallet specifications are agreed before production. A typical export carton holds 12 to 24 bottles with a gross weight under 15 kg for manual handling, and pallets are built to a 1,200 by 1,000 mm or 1,200 by 800 mm footprint with a stated tier count and stretch wrap. We provide carton dimensions, net and gross weight, and pallet quantity so your freight forwarder can calculate volume before booking. Amazon FBA shipments need the carton label and pallet label formats confirmed in advance, and we check them against the shipment plan before the goods leave the factory.

Artwork proofing is a formal step. You supply the print-ready file, we return a proof showing dieline, colour separation and code placement, and production does not start until the signed proof is on file. This catches label errors such as a missing allergen statement or a serving size that does not match the formula. For private-label iron gummies the label carries your brand and your responsible-person details, and we remain the identified manufacturer where your market requires it.

The sample stage runs 7 to 10 working days for a formula and flavour sample, longer if a new shape tool is needed, which adds roughly 15 to 20 working days for tooling. Samples are sent by courier at the customer's account and include a draft specification and a preliminary label for reference. Once you approve the sample and pay the deposit, mass production takes 20 to 35 working days depending on flavour count, packaging format and whether the line is already running your gummy size. Pilot runs from 1,000 units are available before you commit to the 1,000 unit retail MOQ.

Shipping is quoted on your chosen Incoterm. EXW means you collect from the Guangdong factory, FOB covers delivery to the named port, and DDP places the goods at your warehouse with duty and clearance handled. Air freight suits pilot and launch volumes and typically takes 5 to 10 days door to door, while sea freight takes around 25 to 40 days depending on the destination port and whether it is a full container or LCL. We book on your forwarder or quote through ours, and we share the packing list and commercial invoice before dispatch.

The document pack issued with each shipment includes the certificate of analysis per batch, a material safety data sheet, a free-sale certificate, and a certificate of origin. Where the destination requires it, we arrange a health certificate or phytosanitary certificate through the relevant authority, and halal certificates are provided when the run is certified. Documents are checked against the commercial invoice and packing list so that the consignee, description and quantity match at customs.

Lead times are counted from deposit receipt and approved artwork, not from the enquiry date, and they assume the iron salt and packaging are in stock. If a specific ferrous salt or a custom bottle has a longer inbound lead time, we flag it at quotation so the schedule is realistic. For repeat orders we hold the approved formula, artwork and specification on file, which shortens the next run because sampling and proofing are already closed out.
