Collagen Powder Manufacturer for Bulk and Private Label

Collagen peptide powders are hygroscopic and prone to clumping when humidity rises above 45% RH. The plant runs two V-blenders at 500 kg and 1,000 kg batch sizes with humidity-controlled rooms at 40–45% RH. That range keeps flowability stable through the filler without adding anti-caking agents beyond the 1–2% typically needed for retail bottles.

Filling runs on three lines: a 6-head auger filler for 150 g–1 kg bottles, a stick-pack line for 2 g–10 g sachets, and a bulk line for 10 kg and 25 kg drums. Changeover between SKUs takes 2–4 hours including cleaning verification. A 1,000-unit launch run and a 30,000-unit reorder use the same equipment settings, so dose weight stays within ±3% across batches.

Most retail collagen powders use hydrolysed bovine or marine peptide with a molecular weight between 2,000 and 5,000 Da. Bovine type I and III suits joint and skin claims; marine type I is common in beauty SKUs. Vegan alternatives include fermented collagen-like peptides or amino acid blends, though label claims differ by market and should be checked against local rules before printing.

Standard doses run 5 g, 10 g and 20 g per serving. Flavour systems are built around natural flavours, stevia or monk fruit, and citric or malic acid for tartness. Vitamin C at 40–80 mg per serving is a common addition because it supports normal collagen formation. We can also add hyaluronic acid, biotin or elastin, but each addition raises the MOQ to 5,000 units per SKU.

Every batch is tested for identity, heavy metals, microbial limits and moisture before release. Third-party lab reports from SGS or Intertek are available on request. The facility is GMP-certified, ISO 22000 and HACCP compliant, and holds halal certificates for markets that require them. For EU shipments, we provide the necessary documentation for customs clearance, though the importer remains responsible for final market compliance.

Export packing uses food-grade liners inside fibre drums or corrugated cartons. Shelf life is typically 24 months in sealed bottles and 18 months in stick packs. Shipping from Shenzhen or Hong Kong ports takes 18–35 days to the US or EU depending on the route. Air freight for samples or urgent launches takes 3–7 days. We handle FOB, CIF and DDP terms depending on your freight setup.

Every collagen powder batch is tested against a written specification before release. Identity is confirmed by FTIR or HPLC against a reference standard, and potency (protein content and collagen peptide profile) is assayed by Kjeldahl or HPLC. Microbial testing covers total aerobic count, yeast and mould, E. coli, Salmonella and Staphylococcus aureus. Heavy metals (lead, arsenic, cadmium, mercury) are tested by ICP-MS. Moisture is checked to confirm the below 5% target. Tests run on incoming raw material, on the blended bulk before filling, and on the finished packed lot.

The certificate of analysis (COA) issued with each lot lists the product name, lot number, manufacturing date, expiry date, tests performed, specification limits and results. It also names the testing laboratory and the release signature. Where a customer needs a specific method, such as a particular HPLC column or a third-party lab, that is written into the specification before the first batch. We do not issue a COA until all results are within specification.

Retention samples are kept for every batch: at least two finished units per lot, stored under label conditions, for the full shelf life plus six months. Stability follows a bracketed protocol with time points at 0, 3, 6, 12, 18 and 24 months, testing moisture, appearance, microbials and potency. Accelerated data at 40°C/75% RH supports the initial shelf-life claim, and real-time data confirms it. Customers can request the stability summary for their formula before signing off artwork.

Deviation handling is documented. If a batch fails a specification, it is placed on hold, investigated and either reworked within the approved process or rejected. Retained records include batch records, equipment logs, cleaning records and deviation reports, and are available for customer audit. This is the documentation a brand needs when a retailer or importer asks how the collagen powder was made and released.

Collagen powder fills into several pack formats. Wide-mouth HDPE or PET jars suit 200 g to 1 kg with a 5 g to 20 g scoop, and stick packs run from 2 g to 10 g for single-serve use. Sachets and pouches are available for larger single doses or sample packs. We can also fill into composite cans or doypacks with a zipper. Closure, liner and scoop options are confirmed at sample stage. Bottle and stick-pack filling lines run at up to 60,000 bottles or 400,000 stick packs per day, so packaging choice affects scheduling more than capacity.

For the US market, the label must carry the statement of identity, net quantity, ingredient list, allergen declaration where applicable and the supplement facts panel with serving size and percent daily value. We check that the label artwork matches the approved formula and fill weight before printing. Lot number and expiry date are inkjet-coded on the base or crimp of each unit, and the same code appears on the carton. Cartons are specified with gross weight, dimensions and units per carton, and pallets are built to a stated carton count and height for container loading.

Retail and e-commerce compliance is handled at packing. For Amazon, we can apply FNSKU labels and poly-bag units where required, and build cartons to the marketplace's weight and size limits. For retail, we check barcode placement and can add a peggable or shelf-ready carton. We do not print regulated claims on your behalf; the brand owner approves final artwork. What we do is confirm that the printed lot, expiry and net content match the batch record so the packed goods are ready for the importer or fulfilment centre.

Sampling starts with a formulation brief and a target dose. Stock collagen base samples are available in 7 to 10 working days; a custom flavour or a new blend adds 5 to 7 days for bench work and sensory approval. The sample you sign off becomes the reference standard for the production batch, so flavour, colour and fill weight are matched to it. MOQ is 1,000 units per SKU when a brand needs market feedback before a full order.

Mass production runs 20 to 35 working days after sample sign-off and receipt of packaging components. That window covers blending, filling, coding, cartoning and release testing. If packaging is supplied by the brand, add transit time to the plant. We schedule around Chinese New Year and other peak periods, so a confirmed order placed before the holiday avoids a four to six week gap. Repeat orders on the same formula and pack move faster because artwork and specification are already approved.

Delivery is quoted EXW, FOB or DDP. Sea freight suits full containers and larger reorders; air freight suits launches and sample quantities. We provide a commercial invoice, packing list, COA, MSDS, free-sale certificate and, where the destination requires it, a phytosanitary certificate or non-GMO statement. Incoterms and documents are agreed before production, not after, so the importer knows exactly what arrives with the container.
