Electrolytes Liquid Manufacturer for Private Label Brands

EUPHM operates four liquid filling lines for electrolyte products. Two lines handle 30ml and 50ml PET bottles with induction sealing and shrink sleeves. One line runs 15ml stick packs at 400,000 units per day. The fourth line fills 250ml to 750ml HDPE or PET bottles with sport caps. We use hot-fill at 85°C for shelf-stable formulas and aseptic filling for heat-sensitive ingredients like vitamin C and B-complex.

Changeover between SKUs takes 4-6 hours, which keeps small batch runs economical. Nitrogen flushing is available on all lines to protect oxidation-prone electrolytes and flavours. For carbonated electrolyte drinks, we have a separate filler with 2.5 volumes CO2. Every line runs inline metal detection and checkweighing. Typical fill accuracy is ±1.5% for bottles and ±2% for stick packs. We can also run shaped sachets and 1L pouches for bulk or food service.

A standard oral rehydration formula uses 500-700mg sodium, 300-500mg potassium and 50-100mg magnesium per 500ml. For sports drinks, sodium can reach 1,000mg per bottle. EUPHM keeps a library of 40+ electrolyte base blends using sodium citrate, potassium chloride, magnesium citrate and sea salt. We adjust osmolality to 200-280 mOsm/kg for faster gastric emptying. Sweetener systems include cane sugar, allulose, stevia, monk fruit and sucralose.

Flavour matching is done in-house with 12 natural and 20 nature-identical options. Common profiles are lemon-lime, berry, orange, watermelon and coconut. We can match a competitor sample within 3-5 iterations. pH is controlled between 3.2 and 4.0 for microbial stability. Preservative-free options use hot-fill or aseptic processing. For keto and zero-sugar claims, we test final sugar content below 0.5g per serving. All formulas are locked with a signed specification sheet before production.

EUPHM is a GMP-certified facility with ISO 22000 and HACCP. We are FDA-registered for US export. Each batch has a certificate of analysis covering sodium, potassium, magnesium, pH, Brix, total plate count and yeast/mould. Heavy metal testing (lead, arsenic, cadmium, mercury) is done per finished lot. We retain samples for 24 months. For halal claims, we source certified raw materials and run dedicated cleaning between runs.

Shipping from Guangdong covers FOB Shenzhen or Hong Kong. A 20ft container holds about 22,000 bottles of 500ml or 180,000 stick packs. We prepare export documents including commercial invoice, packing list, health certificate and certificate of origin. For EU clients, we can provide a statement of compliance with EC 178/2002. Lead time from deposit to port is 25-40 days depending on format and order size. Air freight for samples or urgent runs takes 5-7 days.

Every electrolyte liquid batch is tested against a written specification before release. Incoming raw materials are checked for identity and potency: sodium chloride, potassium citrate and magnesium gluconate are assayed by titration or HPLC, and water is tested for conductivity and microbial count. During production, fill weight is verified every 30 minutes on a calibrated checkweigher, with a tolerance of ±2% for bottles and ±3% for stick packs. Brix and pH are monitored at the start, middle and end of each run to confirm the formula remains within the approved range.

Finished product testing covers microbials (total plate count, yeast and mould, E. coli, Salmonella), heavy metals (lead, arsenic, cadmium, mercury) and potency of the declared electrolytes. For liquid formats, we also test seal integrity and, where applicable, preservative efficacy against a standard challenge test. Results are recorded on a certificate of analysis (COA) that lists the batch number, production date, expiry date, test methods and specification limits. A COA is issued with every shipment, and a retained sample from each batch is kept for 24 months.

Stability follows an accelerated protocol at 40°C and 75% relative humidity for three months, plus real-time testing at ambient conditions for the declared shelf life. We test at 0, 1, 2, 3, 6, 12 and 24 months for pH, colour, flavour, microbial count and electrolyte potency. If a formula contains heat-sensitive vitamins or botanicals, we recommend aseptic filling and nitrogen flushing to reduce degradation. Stability data is available to brand owners under a confidentiality agreement, and we can run a custom stability study for new formulations at a fee that is credited against the first production order.

Retention samples are stored in the original packaging at 25°C and 60% relative humidity. For each batch, we keep at least 12 units for bottles and 30 units for stick packs. These samples are used for complaint investigations and annual product reviews. If a deviation is found during testing, the batch is placed on hold and an investigation report is issued within five working days. We do not release a batch without a signed quality release from the QA manager.

Liquid electrolytes are filled into PET bottles, glass bottles, stick packs and sachets. Standard bottle sizes are 250ml, 500ml and 750ml, with 30ml shots and 15ml stick packs for single-serve formats. Caps can be screw-top, sports cap or tamper-evident. For stick packs, we use a three-layer laminate with a tear notch and a registered print area of up to six colours. We can apply shrink sleeves, pressure-sensitive labels or direct print. Carton specifications are agreed per SKU: typical is a 12-bottle shelf-ready carton with a corrugated board grade of 32 ECT, and pallet configuration of 48 cartons per layer, 6 layers high, stretch-wrapped and edge-protected.

For the US market, we prepare FDA dietary-supplement labels with the required statement of identity, net quantity, supplement facts panel, ingredient list, allergen declaration and the address of the distributor. We do not write the supplement facts panel for you, but we check that the values match the formula and that the label includes the mandatory 'Distributed by' or 'Manufactured for' line. Lot and expiry coding is applied by inkjet or laser on the bottle shoulder or the stick pack seal, in a format agreed with your quality team. We can also add a QR code for batch traceability.

For Amazon and retail compliance, we can print and apply FNSKU labels, poly-bag units with a suffocation warning where required, and pack to Amazon's carton weight and dimension limits. We do not register your brand on Amazon or handle FBA shipments, but we can prepare cartons with the correct FBA box labels and provide a packing list that matches your shipment plan. Retail-ready packaging such as display trays and shelf-ready cases is available on request, with a minimum of 1,000 units per SKU.

Before mass production, we provide a digital label proof and a physical pre-production sample for your approval. Any change to label artwork, bottle type or cap after approval may add 5-7 working days to the lead time. We keep a labelled retention sample of each batch for 24 months, which helps if a retailer or marketplace asks for evidence of the label as shipped.

The sample timeline starts with a formulation brief and a target specification. We can supply a stock electrolyte base for tasting within 7-10 working days, or develop a custom formula in 10-15 working days. Sample costs are quoted per SKU and include courier delivery; the cost is credited against the first mass production order above 1,000 units. For pilot runs, the MOQ is 1,000 units per SKU, and for retail bottling it is 1,000 units per SKU. Stick packs have a lower MOQ of 5,000 units per SKU because of set-up waste on the filling line.

Mass production takes 20-35 working days after sample approval and receipt of the deposit. This window includes raw material procurement, filling, labelling, QC testing and packing. If your formula requires a new flavour or a custom bottle, add 10-15 working days for tooling and stability checks. We provide a production schedule at order confirmation and update it weekly. For repeat orders with the same specification, the lead time is typically 20-25 working days.

We ship under EXW, FOB Shenzhen or Hong Kong, and DDP for selected destinations. Air freight is used for samples and urgent orders up to 500kg, with a transit time of 5-8 days to the US or EU. Sea freight is standard for full containers: a 20ft container holds approximately 1,200 cartons of 12 bottles, and transit to the US West Coast is 18-25 days. We provide a commercial invoice, packing list, bill of lading, COA, MSDS, free-sale certificate and, where relevant, a phytosanitary certificate for botanical ingredients. We do not provide a certificate of origin unless requested, which adds 2-3 working days.

For DDP shipments, we handle customs clearance and duty payment, and deliver to your door. We recommend DDP for first orders to reduce customs risk, and FOB for repeat orders where you have a freight forwarder. All documents are sent electronically before shipment, and the original set is couriered with the goods or released against payment, as agreed in the sales contract.
