Cod Liver Oil Liquid Manufacturer for Private Label Brands

EUPHM runs two dedicated liquid lines for oils and water-soluble liquids. Bottle sizes from 50 ml to 1,000 ml are handled on the same platform, with changeover under four hours. Filling accuracy is ±1% by weight, checked every 30 minutes. Nitrogen flushing is standard for cod liver oil to displace headspace oxygen; residual oxygen is held below 2% where the formula requires it. Caps range from standard screw caps to child-resistant and tamper-evident closures for US and EU retail.

Capacity is up to 60,000 bottles per day across two shifts. That covers a 1,000-unit pilot and a 250,000-unit seasonal run without moving to a second supplier. Amber PET, clear PET and flint glass are stocked; dropper inserts, metered pumps and dosage cups are available as secondary packaging components. Cartoning, shrink-wrapping and export palletising are done in-house, which shortens the gap between bulk fill and a shippable finished good.

Cod liver oil is not a single ingredient. It varies by species, season and refinery. EUPHM works with Norwegian and Icelandic cod liver oil, typically 1,000 mg or 1,100 mg per 5 ml serving, and documents vitamin A and D3 levels per batch. Natural vitamin E (mixed tocopherols) is added at 0.05–0.2% to slow oxidation. Lemon, mint and orange oils mask the marine note without synthetic flavour systems. For vegan-positioned lines, algal D3 and flaxseed or algal oil bases are available, though these are not cod liver oil and are labelled separately.

Every formula is built to the target market. EU and UK labels need vitamin A and D per 100 ml and per serving; US labels need % Daily Value based on the current FDA reference amounts. Middle East buyers often ask for halal-certified gelatine-free capsules alongside the liquid, and EUPHM can supply both from the same batch record. Stability testing runs at 25°C/60% RH and 40°C/75% RH for 6 months, with peroxide value and anisidine value checked at 0, 3 and 6 months.

The facility is GMP-certified and holds ISO 22000 and HACCP. It is an FDA-registered facility, which supports US import filing but is not an FDA approval. Halal and organic certificates are available on request; organic cod liver oil requires a certified supply chain from the fishery, and EUPHM will confirm availability per project. Heavy metals, PCBs and dioxins are tested per batch against EU and US limits. COAs are issued in English and can be matched to your specification before release.

Shipping runs from Shenzhen and Hong Kong ports, with air freight for samples and small pilot batches. Typical sea transit is 25–35 days to US West Coast, 28–40 days to EU ports, and 18–28 days to Jebel Ali. EUPHM prepares commercial invoices, packing lists, health certificates and, where needed, certificates of origin. For first orders, a 30% deposit and 70% against bill of lading is standard; repeat orders can move to 30/70 against copy documents.

Every cod liver oil liquid batch is sampled at three points: raw oil intake, post-blending before filling, and finished bottles from the line. Identity is confirmed by fatty acid profile (EPA, DHA, and the characteristic C16:1 and C18:1 ratios for Gadus species), vitamin A and D3 by HPLC, peroxide value and anisidine value to track oxidation, and microbials by total plate count, yeast and mould, E. coli and Salmonella. Heavy metals (lead, cadmium, mercury, arsenic) are tested per batch against EU and US limits, and PCB and dioxin testing is available on request for EU-bound lots.

A certificate of analysis is issued per batch and includes the batch number, production date, best-before date, fill volume, vitamin A and D3 potency in IU or µg, peroxide value, microbial results, heavy metals, and a statement of conformity to the agreed specification. Where a customer supplies a target potency, the COA reports the measured value against that target with the analytical method named. Retained samples of every batch are stored at 5 °C and 25 °C for the full shelf life plus six months, so any post-market query can be checked against the original oil.

Stability follows a bracketed protocol: real-time data at 25 °C and 30 °C over 24 months, with accelerated conditions at 40 °C and 75% relative humidity for six months. Vitamin A and D3 retention, peroxide value and sensory attributes are checked at 0, 3, 6, 12, 18 and 24 months. For a 24-month shelf life claim, the real-time data set must cover the full period before the claim is printed, or the label carries a shorter date until the data matures. Customers receive the stability summary with the first production batch.

The liquid line fills amber and clear PET, amber glass and food-grade HDPE in 100 ml, 120 ml, 240 ml, 250 ml and 500 ml. Closures include tamper-evident screw caps, dropper inserts and measured-dose cups. For markets that prefer single-serve formats, the same oil can be filled into 10 ml stick sachets or 5 ml monodose bottles, though these run on a separate line and carry a higher unit cost. Bottle and carton dimensions are confirmed at sample stage so retail shelf-fit and shipper calculations are fixed before mass production.

Labels are checked against the destination market before printing. For US dietary supplements, the panel includes the Supplement Facts box with vitamin A and D IU or µg per serving, other ingredients, net quantity, and the mandatory allergen and 'keep out of reach of children' statements. EU labels carry nutrition declaration per 100 ml and per serving, the food business operator address, batch and best-before, and storage instructions. Lot and expiry are inkjet-coded on the bottle shoulder and the carton, with the same code on both so retail receiving can match unit to case.

Cartons are specified with the customer's dieline, board grade and print process, typically 300–350 gsm FBB with matt or gloss lamination. Shipper cases hold 12, 24 or 48 units, and pallet patterns are calculated to maximise container fill: a 20 ft container typically holds 8–10 pallets of 500 ml bottles at 1,200–1,400 cases per pallet depending on case count. For Amazon sellers, EUPHM applies FNSKU labels, polybags where required, and carton weight and dimension data formatted for FBA inbound, provided the seller supplies the FNSKU file before packing.

Sampling starts with a 7–10 working day turnaround from approved artwork and specification, covering a 100–250 ml filled bottle with a printed mock label. Sample cost is quoted per project and credited against the first mass production order above 1,000 units. Mass production runs 20–35 working days after sample approval, depending on bottle and carton lead times. Pilot runs from 1,000 units are available on the same line, with a fixed setup charge, so a brand can test a market before committing to a full container.

Shipping is quoted by air or sea. Air freight suits pilot and replenishment orders of 100–500 kg and moves in 5–8 days door to door. Sea freight is used from 1 pallet upward, with transit of 25–35 days to EU and UK ports and 18–28 days to US west coast ports, plus customs clearance. Incoterms offered are EXW, FOB Shenzhen or Hong Kong, and DDP for selected destinations where the customer prefers a landed-cost price. DDP quotes include duty and clearance but exclude destination storage beyond the agreed free days.

Each shipment is accompanied by a batch COA, a material safety data sheet, and a free-sale certificate where the destination requires one. For plant-based ingredients a phytosanitary certificate is issued; cod liver oil is an animal-derived product, so the relevant document is a health certificate for fishery products where the importing country asks for it, together with the halal certificate if that claim is on the label. Commercial invoice, packing list and bill of lading are issued in the customer's name, and documents are shared as PDFs within 48 hours of shipment.
