Tablet Manufacturer for Dietary Supplements

Our tablet manufacturing lines handle both single-layer and bilayer compression. Standard round and caplet tooling is available in-house. For custom shapes or embossing, tooling lead time is 15–20 working days and we store it for repeat orders. Production capacity runs at 2–4 million tablets per day across multiple compression suites, which keeps 20–35 day lead times realistic even for multi-SKU launches.

We run hardness, thickness and weight checks every 30 minutes during compression. Weight variation is held to ±3% for uncoated tablets and ±5% for coated tablets. If your formula includes hygroscopic actives or volatile ingredients, we adjust granulation and compression parameters to protect stability. Batch sizes scale from 50 kg pilot runs to 500 kg commercial runs without changing the tooling.

Film coating improves swallowability and masks bitter actives. We offer aqueous film coating in clear, white or custom Pantone colours. Enteric coating is available for ingredients that need to survive stomach acid, such as probiotics or certain enzymes. For chewable tablets, we adjust binder and sweetener systems to reach a clean mouthfeel without chalkiness, using mannitol, sorbitol or sucralose as your label allows.

Effervescent tablets require low-humidity production and foil packaging. We run these on dedicated lines at 15–20% relative humidity. Bilayer tablets let you separate incompatible ingredients, for example a mineral in one layer and a vitamin in another. Our formulation team reviews your actives for compressibility, flow and potential interactions before we commit to a batch record.

Every batch is tested for identity, potency, uniformity of dosage units and microbial limits. We hold GMP, ISO 22000 and HACCP certifications. Our facility is FDA-registered. Certificates of analysis are issued per batch, and we retain samples for 12 months after the expiry date. Heavy metals, residual solvents and pesticide panels are available on request for EU and US market entry.

For export, we prepare halal and organic certificates where the ingredient list qualifies. Documentation includes commercial invoice, packing list, certificate of origin and health certificate. We ship FOB Shenzhen or Yantian, or arrange air freight for urgent pilot batches. Typical port-to-port transit is 18–28 days to US West Coast, 22–30 days to EU ports and 12–20 days to Middle East hubs.

Every tablet batch is tested against a written specification at three points: incoming raw materials, in-process compression, and finished goods. Identity and potency are confirmed by HPLC or UV-Vis against a reference standard. Microbial limits follow USP <2021> or <2022> as applicable, with total aerobic count, yeast and mould, E. coli and Salmonella screened. Heavy metals (lead, arsenic, cadmium, mercury) are tested by ICP-MS on the finished tablet, not just the raw material. Disintegration testing runs on six tablets per batch using the basket method at 37°C; film-coated tablets are also checked for appearance and weight variation across the compression run.

A certificate of analysis (COA) is issued per batch and includes the product name, batch number, manufacturing date, expiry date, specification limits, test methods, results and a pass/fail statement signed by the QC manager. Where a customer needs a specific marker compound, the COA reports the assay value against that marker. Retention samples of every batch are held for the shelf life plus 12 months, stored under labelled conditions. Stability testing follows a bracketed protocol: 0, 3, 6, 12, 24 and 36 months at 25°C/60% RH, with accelerated conditions at 40°C/75% RH for six months. Customers can request interim stability reports before committing to a full shelf-life claim.

In-process controls are recorded on the batch manufacturing record (BMR), which is reviewed and released by QA before packaging. The BMR captures granulation parameters, compression force, tablet hardness, friability (target under 1% after 100 drops), thickness and average weight. Any deviation is logged and investigated before release. For export orders, the COA is issued in English with the customer's product name and label claim, and can be legalised or apostilled if the destination market requires it. We do not issue COAs for products we did not manufacture, and we do not alter results to match a target label claim.

Tablets can be packed in HDPE bottles with induction seals and child-resistant or standard caps, in PVC/PVDC or alu-alu blisters, in single-dose sachets, or in stick packs for effervescent and chewable formats. Bottle sizes run from 30 cc to 500 cc, with desiccant or cotton options depending on the formulation's moisture sensitivity. Blister tooling is quoted per SKU; standard cavity counts are 10, 12 or 14 per card. Cartons are printed to the customer's artwork, with lot number and expiry date applied by inkjet or laser at the time of packing. We can also apply a tamper-evident shrink band and a QR code linking to a batch record if the brand requires it.

For the US market, the label must carry a Supplement Facts panel with serving size, amount per serving, % Daily Value where established, and a list of other ingredients in descending order of weight. The principal display panel needs the product name, net quantity and, for tablets, the count. Allergen declarations follow FALCPA. For the EU, Regulation 1169/2011 applies, with nutrition declaration and allergen highlighting. We review artwork against the destination market's rules before printing, but final legal responsibility for the label rests with the brand owner. We do not write health claims or structure/function claims on the customer's behalf.

Lot coding is alphanumeric and unique per batch, with the expiry date calculated from the stability protocol agreed at order confirmation. Cartons are packed to a standard count per shipper, typically 12, 24 or 48 units, and palletised to a maximum height of 1.8 m with stretch wrap and edge protectors. For Amazon FBA, we can apply FNSKU labels and poly-bag units with the required suffocation warning, and pack to Amazon's carton weight and dimension limits. Retail compliance for major chains may require a GS1 barcode on the carton and a specific pallet configuration; both are quoted at the packaging specification stage, not after production.

Sample requests are quoted at 1,000 units for pilot runs and are typically dispatched within 7–10 working days of formula and artwork approval. Sample costs are credited against the first mass-production order. Mass production runs 20–35 working days after sample approval, depending on coating requirements, packaging complexity and whether stability testing is required before release. Orders above 100,000 units per SKU are scheduled in campaigns and may extend the window by 5–10 working days. We confirm the production slot in writing once the deposit is received and the artwork is signed off.

Air freight is used for samples and urgent retail replenishment, with transit from Guangdong to major EU and US hubs typically 5–8 days door to door. Sea freight is the default for full-container orders: 25–35 days to European ports and 18–28 days to US west coast ports, depending on routing. We quote EXW, FOB Shenzhen or Hong Kong, and DDP for customers who want a landed-cost price. DDP includes duties and customs clearance but excludes any destination-market registration fees, such as FDA facility registration or EU responsible-person fees, which remain with the brand owner.

Every shipment is accompanied by a commercial invoice, packing list, bill of lading or air waybill, certificate of analysis, material safety data sheet where applicable, and a free-sale certificate. For plant-derived ingredients, a phytosanitary certificate can be arranged where the destination requires it. Halal certificates are issued per batch by the relevant certifying body. Documents are sent electronically before dispatch so the customer can pre-clear customs. We do not under-declare value or misclassify goods on shipping documents, and we do not ship without a signed purchase order and deposit.

At volume, nothing beats a tablet on cost per unit or on dose ceiling: 1,000 mg and above is routine, and a scored tablet gives you two doses in one piece. That is why multivitamins, minerals and high-dose botanicals live here. Coating solves the two things people complain about — taste and stomach upset — with film, sugar or enteric coats.

What compression costs you is heat and force. Some actives, especially enzymes, probiotics and certain plant extracts, do not survive the die; those belong in a capsule or a stick pack. Chewables need a completely different binder system and a sweetness profile that masks the actives, and effervescent chemistry cannot be compressed on the same platform at all.

Every formula has a hardness window — typically 6–12 kp — where the tablet is strong enough to survive bottling and shipping but still dissolves inside the spec. Run too hard and dissolution fails; too soft and friability climbs above 1% and you ship dust. We control weight to ±3%, measure thickness and hardness hourly, and use pre-compression to deaerate the fill so the main compression does not laminate.

Granulation is where most tablet problems are decided: moisture at 1–3% before compression, particle size distribution stable batch to batch, and a lubricant blend time that is long enough to prevent sticking but short enough not to destroy hardness. Coated tablets add pan inlet temperature and spray rate to the batch record. Dissolution and uniformity of content are run on every batch, not on a sample of batches.
