What to Prepare Before Contract Manufacturing

Why a brief comes first

Contract manufacturing is a partnership in which your brand and a production partner share one product. The partner can plan only what it understands. A vague request such as a liquid detergent produces a long list of questions. A clear brief produces a feasibility answer and a quotation.

UniPharma works on chemicals, detergents and feed additives, with services agreed per order. The process follows a simple route: brief, formulation and sample, batch production, filling and packing, then quality control and dispatch. See the manufacturing and filling page.

Product and formula

• What the product is: a chemical blend, a cleaning product or a feed additive premix.
• Your formula, if you have one: ingredients, grades and proportions. If you do not, describe the target performance and any reference product so a formula can be developed with you.
• Critical ingredients: any raw material that must come from a particular source or grade.
• Appearance and physical targets: colour, viscosity, pH range, form (liquid, powder, granule).

Pack, label and presentation

• Pack format: bottles, jerrycans, drums or sacks, and the size of each.
• Closure and material: cap type, tamper evidence, plastic type if you have a preference.
• Label and artwork: final label text, regulatory statements and barcodes. Private-label filling is available on request.
• Shipping carton: units per carton and any palletising rules.

Volumes and quality specifications

State your first batch size, your expected monthly or annual volume and how often you will reorder. Small trial runs and recurring orders are both welcome, but planning depends on the figures. Then list the parameters you want verified before dispatch, for example appearance, pH, density, assay or fill volume, together with the acceptance range for each. Batch records are kept per order, and the QC unit checks against the parameters agreed in advance.

Documents and the approval route

Agree early who approves the sample, who approves the final label and what paperwork travels with each shipment. If you need raw materials sourced as part of the project, review our cosmetic and cleaning raw materials so the formula is built on available items.

Common pitfalls and how to avoid them

Projects slow down in predictable places. The first is a formula that has only ever been made in the laboratory, where a small beaker behaves differently from a large blending tank. Allow time for a pilot batch and for adjusting mixing order, temperature and addition rates.

• Changing the label text after printing has started, which wastes materials and time.
• Not agreeing the acceptance range for each QC parameter before production.
• Leaving the pack closure and bottle choice until the end, even though they affect filling speed and leakage tests.
• Underestimating raw-material lead times, especially for items that must be imported.
• Forgetting storage: finished goods need space and conditions agreed with your logistics.

A good habit is to hold a short kick-off review once the brief is complete. Walk through the formula, the pack, the label and the quality checks, and write down every decision. Both sides then work from the same document, and any later change is visible and priced. Services are agreed per order, so the more you specify at the start, the more accurate the plan.

Lastly, decide who owns the formula and the artwork from day one, and write it into the agreement. Clear ownership avoids discussion later, protects your brand and gives both parties confidence to invest time in the product.

FAQ

Do I need a ready formula?

Not necessarily. You can bring your own formula or describe the target and develop one with us. The route is agreed per project.

Can I run a small trial first?

Small trial runs are welcome and are agreed per order.

Who supplies the packaging?

Packaging responsibility is agreed in the brief: either you supply it or it is sourced as part of the order.

How are quality checks defined?

You and the QC unit agree the parameters and acceptance ranges before production, and the batch is checked against them.
