Selenium Capsule Manufacturer for Custom Formulas

The plant runs automatic capsule filling lines with a combined output of 120,000 capsules per hour across two shifts. That covers mid-size retail launches without splitting your order across suppliers. We fill powder, granule and pellet blends, and can run low-dose selenium alongside a carrier such as microcrystalline cellulose or rice flour to keep the blend uniform.

For liquid-fill selenium, we use sealed capsule technology for oil-based formats. Changeover between SKUs is scheduled within the same week where volumes allow, which shortens the gap between your first SKU and your second. Every batch is weighed in-process at 15-minute intervals, and fill-weight data is retained for your batch record.

Selenium comes in several chemical forms, and the form drives your label, your stability data and your price. Selenomethionine is the most common organic choice for capsules, typically dosed at 100 mcg to 200 mcg. Selenium yeast is a food-grade option with naturally bound selenium. Sodium selenite and sodium selenate are inorganic and inexpensive, but they need tighter overage control because of their narrower tolerance.

We blend with common excipients: dicalcium phosphate, magnesium stearate at 0.5–1.5%, and silicon dioxide for flow. If you want a clean-label capsule, we can formulate without magnesium stearate. For combination products, selenium pairs well with vitamin E, zinc, iodine or vitamin C. We test blend uniformity on every batch before encapsulation.

Raw material arrives with a certificate of analysis and is quarantined until our own assay confirms identity and potency. We test selenium content by ICP-MS or AAS, depending on the form. Finished capsules are checked for weight variation, disintegration time and microbial limits. Heavy metals, including arsenic, cadmium, lead and mercury, are tested per batch.

The facility is GMP-certified and holds ISO 22000 and HACCP. We are FDA-registered for dietary supplement manufacturing. halal and vegan certifications are available where the formula and capsule shell allow. Documentation for your regulatory filing, including COA, MSDS and flow chart, is issued with each shipment.

Every selenium capsule batch is tested at three points: incoming raw material, in-process blend, and finished capsules. Identity and potency are confirmed by HPLC or ICP-MS depending on the selenium form. Microbials (total plate count, yeast and mould, E. coli, Salmonella) and heavy metals (lead, arsenic, cadmium, mercury) are run on each lot. Disintegration testing follows USP <701> or the relevant pharmacopoeial method, with a typical specification of complete disintegration within 30 minutes for gelatin and 45 minutes for HPMC.

A Certificate of Analysis (COA) is issued per batch and includes the product name, lot number, manufacturing date, expiry date, tests performed, specifications, results, and the analyst and QA sign-off. We retain samples from every batch for 24 months past expiry under controlled temperature and humidity. Stability protocols follow ICH Q1A(R2) conditions: 25°C/60% RH long-term and 40°C/75% RH accelerated for six months, with potency, microbials and disintegration checked at 0, 3, 6, 12, 18 and 24 months.

In-process checks cover blend uniformity (sampled at top, middle and bottom of the mixer), capsule fill weight (every 15 minutes during filling), and seal integrity for HPMC capsules. Any out-of-specification result triggers a documented investigation and batch hold. We do not release a selenium capsule batch without a completed COA and QA release signature. Documentation is provided in English as standard; other languages can be arranged on request.

We fill selenium capsules into HDPE bottles (30, 60, 90, 120, 180 or 250 count), blister packs, stick packs or sachets. Bottles can include induction seals, desiccant sachets and child-resistant closures. Labelling follows FDA dietary supplement requirements: statement of identity, net quantity, supplement facts panel, ingredient list, allergen declaration, and the manufacturer/distributor address. We also print lot number and expiry date in inkjet or laser coding on the bottle, carton and shipper.

For Amazon FNSKU and retail compliance, we apply FNSKU labels, poly-bag the bottles where required, and print carton markings to your specification. Carton dimensions and pallet configurations are agreed at artwork approval: typical 60-count bottles pack 48 per shipper, 24 shippers per pallet, with pallet height not exceeding 1.8 m for sea freight. We can provide dielines and artwork templates for your designer, and we check print-ready files for barcode scannability (UPC/EAN) before plates are made.

Stick packs and sachets are available in 2 g to 5 g fill weights, with 3-side seal or 4-side seal formats. Blister packs use PVC/PVDC or alu-alu for moisture-sensitive formulas. All packaging components are food-grade and supplied with migration test certificates where applicable. We do not print claims on your label without written substantiation, and we flag any claim that may require FDA notification or structure/function disclaimer.

Sample lead time for selenium capsules is 7–10 working days after formula and artwork approval, including courier dispatch. Mass production runs 20–35 working days after sample approval and receipt of deposit, depending on capsule size, packaging format and whether labels are supplied by you or printed by us. Pilot runs below 1,000 units are quoted separately and may add 5–7 working days because of manual line setup.

We ship by air or sea. Air freight typically takes 3–7 days door-to-door for 100–300 kg; sea freight takes 25–40 days port-to-port depending on destination. Incoterms offered are EXW (factory Guangdong), FOB (Shenzhen or Hong Kong), and DDP for select markets. We provide commercial invoice, packing list, COA, MSDS, free-sale certificate, and phytosanitary certificate where relevant (for example, if herbal excipients are present). Halal certificates are available on request and add 5–10 working days to the timeline.

For repeat orders, we hold your approved artwork and formula on file for 12 months, so reorders skip the sampling stage and move directly to production. Payment terms are 30% deposit with balance against copy of bill of lading, or as agreed for established accounts. We do not guarantee delivery dates until deposit is received and artwork is signed off.
