Before you commit money or approve a production run, ask a contract manufacturer to prove it can make your product at your required volume, explain how quality and delivery will be controlled, and agree in writing who is responsible for costs, changes, defects, intellectual property, and exit. There is no universal checklist or standard lead time: the right questions depend on your product, sales markets, and the laws that apply.
Start with capability, capacity, and schedule
Can the manufacturer make your product at your required volume?
Ask for examples of the same or similar products, the processes and equipment involved, and references or other evidence that supports the supplier’s experience. Then ask what capacity it can commit to during your proposed production window—not simply its theoretical maximum. Find out how much capacity is already booked and whether particular materials, equipment, or processes could constrain your order.
The U.S. Department of Commerce’s Office of Textiles and Apparel (OTEXA) identifies recent production of the same or similar products, capacity, timetables, and supplier expertise as relevant capability information in its FTA Commercial Availability FAQ. That guidance concerns a specific trade process, so treat it as a useful diligence framework, not a rule for every buyer.
What happens between sample approval and delivery?
Request a written, product-specific schedule that separates development, samples, testing, your approval, material procurement, production, inspection, packing, and shipping. Ask what assumptions the dates rely on, which events could move them, and who must notify you if a milestone slips. OTEXA notes that development time varies with product complexity and testing needs; no generic lead time can reliably predict an unspecified product’s schedule.

Define quality and acceptance before production
How will you know the order meets specification?
Ask which product specifications and tolerances govern, what documented quality and inspection processes apply, who conducts in-process and final inspections, and what test records you will receive. Before production begins, agree on how approval samples relate to the production run, the inspection method, defect categories or thresholds, the time allowed to report problems, and the remedy for rejected units. Put the acceptance procedure in the order or agreement rather than relying on an informal understanding.
For U.S. federal procurement, first-article testing and approval can be one method of establishing that a contractor can furnish a conforming product. The Federal Acquisition Regulation (FAR) says decision-makers should consider the effect on cost and delivery, the risk of not using it, and less costly quality methods. This is not a general requirement for private buyers; federal quality requirements also vary by acquisition. See FAR Part 9 and FAR Part 46.
Does your product need a separate quality agreement?
For drugs subject to current good manufacturing practice (CGMP), FDA’s November 2016 guidance recommends a quality agreement that delineates each party’s manufacturing activities and responsibilities. Ask who owns specifications, component-supplier qualification, sampling and testing, equipment and process qualification, material status and inventory control, site operations, audit access, regulatory-inspection communications, and escalation of quality problems. The FDA guidance is specific to drug contract manufacturing; it is not a blanket rule for other industries. Read the FDA guidance.
Identify every production site and control changes
Which facilities and subcontractors will touch the order?
Ask for the legal name and location of every factory that will perform a production step, what each site will do, and the identity and role of any subcontractors or collaborating suppliers. Confirm whether the manufacturer may move production or add a subcontractor without telling you or obtaining approval. OTEXA’s capability review includes subcontractors and collaborators; the FDA’s drug quality guidance calls for agreements to identify sites and their contracted services.

Who approves materials and production changes?
Clarify who buys and approves materials, how substitutions are authorized, how lot identity and records are maintained, and how inventory is stored and reconciled. Set advance notice and approval requirements for changes to materials, processes, equipment, production locations, or subcontractors. Ask how shortages, nonconforming inputs, and quality events will be escalated and recorded. The FDA discusses supplier responsibilities, testing, inventory identification, and material handling for drug manufacturing; apply those details only when the regulated context fits.
Put ownership and confidentiality in writing
Who owns designs, tooling, and project-specific improvements?
Ask the manufacturer to identify any pre-existing technology it will use, then state who owns product designs, drawings, specifications, molds, dies, jigs, fixtures, process documentation, and project-specific improvements. For tooling, settle who pays, where it is stored, who can access or use it, how it is maintained, and how it will be returned or transferred if the relationship ends. Ownership is a contract point to negotiate; there is no universal tooling rule established for every transaction.

The U.S. Department of Commerce’s Pakistan intellectual-property guidance recommends due diligence and explicit contractual treatment of intellectual property and confidential business or trade-secret information. Its legal observations concern Pakistan and should not be generalized to other jurisdictions.
Understand the full cost and payment exposure
What exactly is included in the quote?
Request an itemized quote that separates sample and development charges, tooling or setup, unit prices at relevant quantities, minimum order quantity, packaging, testing, inspection, freight, applicable duties, and recurring fees. Ask which assumptions could change the price and how additional work must be approved.

Confirm the payment schedule, currency, deposit and balance triggers, and any late-payment or cancellation charges. Federal procurement materials recognize price, other costs, payment terms, quality, testing, and delivery as relevant contract or evaluation considerations, but they do not set standard prices or payment terms for private manufacturing orders.

Verify the manufacturer’s legal identity and, where appropriate, ownership, relevant history, references, financial ability, and the authority of the person making commitments. Ask how your order would be affected by a capacity disruption, loss of a key customer, or reliance on a sole-source component. The U.S. Department of Commerce’s New Zealand commercial guidance advises U.S. firms to confirm a partner’s identity, financial ability, and capability to deliver over the contract life. Its framing is country-specific, though those are broadly useful diligence questions. See the guidance.
Agree on remedies and an exit before a problem occurs
Write down what happens after late delivery, failed samples, out-of-spec production, or other defects. Specify how rework, replacement, credits or refunds, cancellation, and force majeure are handled, along with notice and cure periods and dispute resolution. Also agree on return of tooling and inventory, transfer of records, and the handling or destruction of confidential information when the relationship ends. Have counsel review the agreement for the governing law and markets involved; remedies and legal requirements depend on the transaction and jurisdiction.
Compare manufacturers on evidence, not assurances
Use the same questions for each supplier, then compare the answers and supporting documents. A practical scorecard should cover:

The FAR considers supplier financial and technical ability, quality, cost, and delivery in covered federal procurement. It does not govern every commercial order, but those dimensions can help organize a private buyer’s comparison.
