Products Description
Marine Collagen is Type I collagen powder extracted from fish skin and scales via enzymatic hydrolysis; free from BSE/TSE risks, it can obtain Halal and Kosher certificates without porcine enzymes.
Our food-grade marine collagen is white to pale yellow powder with protein ≥90.0g/100g and hydroxyproline ≥3.0g/100g, complying with GB 31645-2018, and specifications like molecular weight and mesh can be customized with batch COA provided.
Widely used in dietary supplements, functional drinks and beauty nutrition products, it suits multiple dosage forms; MOQ starts at 25kg for trial orders, with FOB/CIF shipment available from Qingdao.

Key Benefits of Marine Collagen
Water soluble and easy to formulate
Marine Collagen dissolves readily in water, so it drops into a beverage, a sachet blend or a liquid-filled softgel without a dispersion step. That keeps processing simple and avoids the grit and sediment that poorly soluble proteins leave behind.
Low odour and clean taste
The hydrolysis and filtration steps strip most of the fishy note, so the powder stays close to neutral. Formulators can hold the flavour profile of a drink, a gummy or a jelly while still carrying a collagen dose on the label.
Type I collagen, rich in the three key amino acids
It is mainly Type I collagen, the type found in skin, tendon and bone. Glycine, proline and hydroxyproline make up a large share of the peptides, and hydroxyproline is the marker an incoming goods lab uses to confirm the ingredient is genuine collagen peptide rather than a plain protein filler.
Marine source, no BSE or TSE concern
Fish are not susceptible to bovine spongiform encephalopathy, so marine collagen carries no BSE or TSE risk and no animal-slaughter documentation. For buyers who screen out bovine or porcine material, this removes a whole category of questions up front.
Certifications and Compliance
Halal, Kosher, ISO22000 and FSSC22000 available upon order. COA, TDS, MSDS, allergen and GMO statements are supplied on request, certificate samples attached. Tell us your market & application for document confirmation.
Packaging and Supply
Standard packaging
20 kg net bag with a food grade PE liner. Smaller pack sizes and palletised shipments are available.
Loading
the main port is Qingdao. Shanghai, Tianjin and Guangdong can be arranged depending on terms and logistics. A 20' FCL holds around 10-12 MT with pallets; the exact figure depends on the packaging and is confirmed per order.*
MOQ
25 kg. Send us your application, target molecular weight range, mesh, packaging and destination port.
Delivery time
stock items can often ship quickly.
Terms
EXW, FOB, CFR, CIF or other Incoterms, depending on the shipment.
Storage conditions: cool, dry, dark and clean. Keep it sealed and away from direct sunlight, humidity, heat and strong odours.
Customization
Molecular weight range, mesh and particle size, odour, solubility and dilute-protein level can be adjusted within the factory's process window. Custom packaging, private label and mixed container loads can be arranged. Tell us your target specification, the end product and the destination market, and we will confirm what is available and which documents come with it.
FAQ
Q: Can you provide a COA for Marine Collagen?
A: Yes. We issue batch-specific COAs for every shipment, on request. Each one covers protein, hydroxyproline, total nitrogen, ash, moisture, heavy metals and microbiology.
Q: Can I request a sample before placing an order?
A: Yes. Tell us the application, the quantity you need, your company name, shipping address and destination market. Sample supply and courier arrangements are confirmed separately.
Q: Is Marine Collagen the same as fish collagen peptide?
A: Yes. Marine Collagen, fish collagen peptide and fish collagen hydrolysate all describe the same ingredient: collagen from fish skin or scales, broken down by hydrolysis into short peptides. The CAS number is 9007-34-5.
Q: What is the difference between marine collagen and bovine collagen?
A: Marine collagen comes from fish and bovine collagen from cattle. Marine carries no BSE or TSE risk and is straightforward for Halal and Kosher; bovine needs halal or kosher slaughter documentation and BSE documentation. Marine is also generally lower in molecular weight and easier to dissolve.
Q: Is Marine Collagen an allergen?
A: Fish is one of the major allergens listed in EU Regulation 1169/2011 and under US FALCPA, and hydrolysed fish collagen is not exempt, so a finished product made with it must declare fish in the ingredient list. Please confirm the wording with your own regulatory advisor for your market.
Q: Is Marine Collagen Halal and Kosher?
A: Fish needs no ritual slaughter, so the ingredient itself is generally acceptable under both. The decisive factor is the enzyme used in hydrolysis: with a food-grade microbial protease and no porcine pepsin at any stage, the product is suitable for Halal and Kosher. We can confirm the enzyme route in writing on request.
Q: What molecular weight do you supply?
A: The material meets GB 31645-2018, which requires at least 90% of the peptides to be below 10,000 Da, and the typical commercial range is 1,000-3,000 Da. Tell us the range your product calls for and we will confirm what is available.
Q: Can I make skin, joint or anti-ageing claims on my label?
A: Not for the collagen itself in the EU or UK, where there is no authorised health claim for collagen. Vitamin C does hold an authorised claim for normal collagen formation, which is why it is often part of the same formula. Confirm all claims against the target market's rules before printing.
Q: How should Marine Collagen be stored after delivery?
A: Sealed, in a cool, dry, dark and well-ventilated place, away from direct sunlight, moisture, heat and strong odours. Reseal opened bags promptly.
Q: Can you supply customised specifications?
A: Yes. Molecular weight range, mesh, odour, packaging and documentation can be matched to your target, subject to production confirmation and order quantity.
