Small Batch Supplement Manufacturer for Growing Brands

Small batch runs use the same GMP-certified equipment as large orders. Capsule filling, tablet compression, powder blending and liquid filling all run on lines that handle 1,000 to 500,000 units. The difference is scheduling: we reserve weekly slots for small batches so they do not wait behind million-unit contracts. Changeover between SKUs takes 2-4 hours, including full cleaning and line clearance. That means a 1,000-unit run is economically viable, not a favour.

Tooling is the main cost driver at low volumes. If your capsule size or tablet shape matches existing tooling, there is no tooling fee. Custom tablet shapes or unusual bottle sizes may add a one-time charge of USD 300-1,200 and 5-10 days. For pilot runs under 1,000 units, we can often use stock bottles and labels to keep setup minimal. You get the same batch record, the same QC release, and the same certificate of analysis as a full-scale order.

Ingredient minimums from suppliers are often the hidden barrier. A raw material supplier may require 25 kg of a specialty botanical, enough for 50,000 capsules. We hold over 200 active ingredients in stock at small-batch quantities, from vitamin D3 and magnesium glycinate to ashwagandha extract and probiotics. If your formula needs a custom ingredient, we can source 1-5 kg from our qualified supplier network, though lead time may extend by 10-15 days.

Formulation support is included for small batch projects. Our team checks ingredient compatibility, flowability for encapsulation, and taste masking for powders. We can adjust excipients to fit your target fill weight without changing the active dose. For liquids, we test pH and preservative efficacy at bench scale before committing to a 1,000-unit run. You receive a formulation sheet and a pilot sample before production starts.

Every batch, regardless of size, goes through the same quality gates. Incoming ingredients are tested for identity, potency and heavy metals. During production, we check weight variation every 30 minutes, plus disintegration and hardness for tablets. Finished goods are tested for microbial safety, label claim and stability. You receive a certificate of analysis with actual results, not just a pass/fail statement. Documentation includes batch records, MSDS and allergen statements.

Certifications apply to small batches too. Our facility is GMP-certified, ISO 22000 and HACCP compliant. If you need halal or vegan certification, we produce those runs on dedicated or cleaned lines with the required documentation. FDA-registered facility status is maintained for US-bound products. For EU and UK clients, we provide compliance files for novel food and health claims review. Middle East clients typically require halal certificates, which we arrange per batch.

Every small batch at our plant is tested against a written specification before release. Incoming raw materials are sampled at 100% of containers for identity by FTIR or HPLC, and a composite sample is tested for potency, microbials (total aerobic count, yeast and mould, E. coli, Salmonella), heavy metals (lead, arsenic, cadmium, mercury) and, where relevant, residual solvents. In-process checks cover weight variation every 30 minutes, hardness for tablets and capsule fill weight. Finished batches are tested for potency, disintegration and microbials before packaging. No batch is released without a signed certificate of analysis.

The COA we issue lists the product name, batch number, manufacturing date, expiry date, specification limits and measured results for each test, plus the method used. It is signed by the QC manager and references the retained sample. We keep retention samples from every batch for the full shelf life plus six months, stored under labelled conditions. Stability testing follows a standard protocol: 0, 3, 6, 12, 18 and 24 months at 25°C/60% RH and 30°C/65% RH, with accelerated conditions at 40°C/75% RH for three months. For small batches under 5,000 units, the stability programme can be shared across three consecutive batches of the same formula to keep the cost proportionate.

Documentation for a small batch includes the batch manufacturing record, the batch packaging record, line clearance records, environmental monitoring for the filling room and deviation reports if any parameter fell outside range. These are retained for five years. If you need a technical data sheet or a specification sheet for your retailer, we prepare it from the same batch record. The QC file is available for review during a factory audit, and we can provide redacted copies of the testing methods on request.

Small batches can run in high-density polyethylene bottles from 30 mL to 500 mL, with induction seals and child-resistant or standard caps. Blister packs are available in PVC/PVDC or alu-alu for 10 to 30 units per card. Stick packs run from 5 g to 30 g, and sachets from 2 g to 10 g. For liquids, we fill 15 mL to 60 mL in PET or glass with dropper or pump closures. Minimum packaging quantities follow the component supplier MOQ, so for a 1,000-unit batch we can often use stock bottles and print labels digitally, which avoids a custom bottle tooling cost of around USD 3,000 to 8,000.

Labels are checked against the US FDA dietary supplement labelling requirements: statement of identity, net quantity of contents, supplement facts panel with serving size and percent daily value, ingredient list in descending order of predominance, and the name and place of business of the manufacturer or distributor. We also add allergen statements where applicable, storage conditions, and the recommended use. Lot number and expiry date are inkjet coded on the bottle and the carton, with a format agreed in the artwork approval. We do not print health claims that are not supported by your formulation documentation.

Cartons are specified to your retail or e-commerce requirement. A standard shipping carton holds 12, 24 or 48 bottles, with dimensions and gross weight confirmed at artwork stage. Pallet configuration is typically 48 cartons per layer and 4 to 6 layers high, stretch-wrapped and labelled with pallet ID. For Amazon FNSKU and retail compliance, we can apply the FNSKU label over the barcode, print the carton in the retail-ready format, and provide the carton dimensions and weight in the format your freight forwarder needs. We do not apply retail security tags, but we can leave space for them.

The sample timeline starts with a formulation brief and a target dosage form. We send a quotation within three working days, then produce a sample batch of 100 to 500 units in 7 to 10 working days after the formula and packaging are agreed. Sample cost is quoted separately and is credited against the first production order above 1,000 units. If the sample needs a revision, one round of adjustment is included at no extra formulation fee; further rounds are quoted per change.

Production for a small batch runs 20 to 35 working days after sample approval and receipt of the deposit. This window covers raw material release, blending, encapsulation or tableting, packaging and QC release. If you need a faster slot, we reserve small batch capacity weekly and can confirm a 15-working-day window for stock formulas and stock packaging, subject to raw material availability. We do not promise a date until the purchase order and artwork approval are both in place.

Delivery terms are EXW, FOB Shenzhen or Hong Kong, or DDP to your warehouse. Air freight is typically 5 to 8 days door to door for 100 to 500 kg, while sea freight is 25 to 40 days depending on destination port. For a 1,000-unit batch of 60-capsule bottles, the shipped volume is usually 1.5 to 2.5 cubic metres and 300 to 500 kg gross. Documents provided with each shipment are the commercial invoice, packing list, COA per batch, MSDS where the product contains a hazardous ingredient, free-sale certificate and, for plant-based ingredients, a phytosanitary certificate where the destination country requires it.
