Folic Acid Tablet Manufacturer for Private Label Brands

Our rotary tablet presses run at 150,000-300,000 tablets per hour depending on size and tooling. That covers small launch runs and repeat orders without retooling delays. We compress folic acid alone or in combination with vitamins B6 and B12, iron, or choline. Tablet hardness and friability are checked every 30 minutes during compression.

Folic acid is light-sensitive and hygroscopic in some blends. We use low-humidity compression rooms at 30-40% RH and amber or opaque packaging options. Core tablet weights range from 100 mg to 500 mg. If your label calls for a smaller swallowable size, we can adjust filler ratios of microcrystalline cellulose and dicalcium phosphate.

We source folic acid USP/BP grade from audited suppliers in Europe and China, with certificates of analysis for each lot. Purity is typically 98-102% on assay. For organic or clean-label lines, we offer folate from organic spinach extract or 5-MTHF as an alternative. Vegan tablets use plant-based magnesium stearate and cellulose coatings.

Common excipients include microcrystalline cellulose, croscarmellose sodium, silicon dioxide and stearic acid. We can formulate sugar-free, gluten-free or non-GMO versions. If your market requires a specific dissolution profile, we run USP <711> tests during development. Flavour masking is available for chewable folic acid tablets, though most prenatal and adult lines use a standard film coat.

Each batch is tested for identity, assay, weight variation, hardness, disintegration and microbial limits. We retain samples for 24 months. Our facility is GMP-certified and holds ISO 22000 and HACCP. Halal and vegan certifications are available on request. We are an FDA-registered facility for US-bound shipments.

Export paperwork includes certificate of analysis, certificate of free sale, GMP certificate, halal certificates, and MSDS. We ship FOB Shenzhen or Yantian, with air freight for samples and urgent orders. Lead times are 20-35 working days for mass production after sample sign-off. DHL and FedEx accounts can be used for door-to-door delivery.

Every folic acid tablet batch is tested at three points: incoming raw material, in-process blend and finished tablets. Identity of folic acid is confirmed by HPLC against a reference standard, with potency assay typically 95.0-105.0% of label claim. Microbial testing covers total aerobic count, yeast and mould, E. coli and Salmonella. Heavy metals (lead, arsenic, cadmium, mercury) are screened against USP <232> limits. Disintegration testing follows USP <701> for immediate-release tablets, with a typical specification of not more than 15 minutes at 37°C.

A certificate of analysis (COA) is issued per batch and includes lot number, manufacturing date, expiry date, tests performed, specifications, results and pass/fail status. It also references the finished product specification and the analytical methods used. Where a buyer needs a customer-specific specification, we can add tests such as folic acid uniformity of content or dissolution profiling at additional cost and lead time. COAs are available in PDF and can be linked to a batch record summary on request.

Retention samples of each batch are kept for the shelf life plus 12 months, stored under labelled conditions. Stability protocols follow ICH Q1A(R2) guidance, with accelerated conditions at 40°C/75% RH for six months and long-term at 25°C/60% RH for up to 36 months. We test at 0, 3, 6, 9, 12, 18, 24 and 36 months for assay, disintegration, microbial limits and appearance. Stability data can be shared under confidentiality for buyers who need to support shelf-life claims in their market.

Folic acid tablets can be packed in HDPE bottles with induction seals and child-resistant or non-child-resistant closures, in PVC/PVDC blister packs, in stick packs or in sachets. Bottle sizes range from 30 to 500 counts, with desiccant options for humid markets. Blister cards are available in 10, 14, 21, 30 or 60 count formats. Stick packs and sachets are typically 1-5 g fill weights. We can also supply tablets in bulk for repackaging, with each drum labelled with lot number, quantity and expiry date.

For US-bound products, labels must include the statement of identity, net quantity of contents, supplement facts panel, list of ingredients, allergen declaration where applicable, and the name and place of business of the manufacturer, packer or distributor. We can print FDA-compliant labels from artwork you supply, and we review label proofs against the finished product specification before printing. Lot and expiry coding is applied by inkjet or laser on the bottle, blister or carton. Expiry dating is normally two years from the date of manufacture unless stability data supports a longer period.

Cartons are specified with dimensions, board grade and print process. Standard export cartons hold 12, 24 or 48 retail units, with gross weight typically under 15 kg for manual handling. Pallet specifications follow 1200 x 1000 mm or 1200 x 800 mm footprints, with stretch wrapping and edge boards. For Amazon sellers, we can apply FNSKU labels, poly-bag units and prepare cartons to Amazon's box and weight requirements. Retail compliance checks for EU and UK markets include allergen and nutrition declarations, address of the responsible person and the appropriate health claims wording.

Sampling for folic acid tablets takes 7-10 working days from receipt of your specification and artwork. Samples are supplied with a preliminary COA and a label proof. Once the sample is approved in writing, mass production runs 20-35 working days depending on tablet dosage, packaging format and whether new tooling is required. Orders above 500,000 tablets or with multi-SKU packaging may require an extended schedule, which is confirmed at order review. We provide a production schedule with milestone dates after deposit receipt.

Delivery can be arranged by air or sea. Air freight is typically 5-10 days door to door for small and mid-size orders, while sea freight takes 25-40 days depending on destination port. We quote EXW, FOB Shenzhen or Hong Kong, and DDP for selected markets. DDP pricing includes freight, insurance, duties and customs clearance, and is confirmed per shipment. For FOB terms, we handle export clearance and provide the bill of lading, packing list and commercial invoice.

Shipping documents include the COA per batch, material safety data sheet (MSDS), free-sale certificate, and certificate of origin where required. For plant-based or organic ranges, we can provide phytosanitary certificates or organic transaction certificates where the ingredient and process are certified. Documents are issued in English and can be legalised or attested for markets that require it, at additional cost and lead time. We recommend confirming document requirements before production starts so that any legalisation can run in parallel.
