How to write an RFQ for a food processing or packaging line

Step 1: Define products and saleable output

Start with what customers will buy: product composition, incoming condition, finished specification, pack format and storage requirements. Attach representative product data and drawings. For variable products, describe the difficult operating cases, such as sticky ingredients, fragile pieces or inconsistent dimensions.

Document the product mix and identify which products need contractually defined performance criteria. Separate mandatory capabilities from future options. A common mistake is requesting a versatile line without defining its limits; suppliers then price different interpretations of flexibility.

Step 2: Establish a capacity basis

State required saleable output with units, shift patterns and production schedules. Distinguish incoming mass from finished output and gross machine speed from sustained line performance. Include yield assumptions, reject handling, cleaning time, changeovers and expected upstream supply interruptions.

Attach a simple mass balance and operating scenario for each representative product. Ask suppliers to identify bottlenecks and proposed buffers. Do not equate a filler’s maximum speed with line capacity: inspection, sealing, cooling or downstream handling may constrain output.

Choose the quotation basis before issuing your RFQ

Step 3: Document hygiene and packaging requirements

Describe hygiene zones, allergen changeovers, cleaning methods and product-contact material requirements. Identify applicable destination-market rules and customer standards for supplier confirmation. State who validates cleaning and food safety controls; an equipment declaration does not establish compliance for the whole process.

For packaging, attach material specifications, dimensions, tolerances and seal requirements. Define coding, traceability, inspection and reject verification. Request trials with representative materials where performance is uncertain. Avoid specifying only a pack photograph: appearance does not establish machinability or barrier performance.

Step 4: Fix site conditions and scope boundaries

Provide a dimensioned layout showing access, hygiene flows, elevations, floor constraints and maintenance space. List available utility capacities and conditions, including electrical supply, water quality, compressed air, heating, refrigeration and drainage. Mark unverified data explicitly rather than presenting assumptions as facts.

Create an interface register assigning responsibility for conveyors, controls, pipework, civil works and commissioning. Require utility consumption and peak demand from each supplier. Replace vague exclusions such as ‘installation by others’ with named work packages and clearly defined connection points.

Step 5: Specify acceptance and handover

Define factory acceptance testing and site acceptance testing before requesting a quotation. State trial products, packaging materials, operating conditions, duration, measurement methods and pass criteria. Cover sustained throughput, product quality, rejects, changeovers and relevant consumption guarantees rather than relying on demonstration videos.

Allocate responsibility for test materials, operators, laboratory checks and repeat trials. Document the remedy process for failed tests and link contractual milestones to agreed evidence. Require manuals, training, maintenance schedules, spare-parts lists and controls backups as part of handover.

Step 6: Standardise commercial responses

Issue a pricing template separating equipment, tooling, freight, installation, commissioning, training and recommended spares. Request currency, quotation validity, payment milestones, delivery basis, taxes and exclusions. Ask what triggers the delivery schedule, including drawing approval, deposit and receipt of samples.

Compare total installed cost and operating cost, not headline price alone. Collect labour, utilities, consumables, maintenance and service assumptions on a common basis. Ask suppliers to state warranty conditions and local support arrangements. Keep optional upgrades separate from the compliant base offer.

Step 7: Issue, clarify and evaluate

Send a controlled RFQ package with a document index, revision number, response deadline and clarification process. Require a compliance matrix marking each requirement as compliant, qualified or excluded. Share material clarifications with all bidders so quotations remain comparable.

Evaluate technical fit before commercial ranking, then close deviations in writing. Record unresolved risks, responsible parties and required evidence. Do not select solely on the lowest quotation or accept substitutions without review; freeze the agreed scope before purchase approval.
