URL: https://jjprojectsok.com/knowledge/how-to-write-an-rfq Español: https://jjprojectsok.com/es/knowledge/how-to-write-an-rfq Updated: 2026-10-15 What an RFQ for industrial materials must specify: item, size, schedule or class, grade, standard, quantity, MTRs, inspection, packing and Incoterm. **In short:** A request for quotation (RFQ) for industrial materials must let a supplier quote without guessing. State the item, size, schedule or class, material grade, governing standard, quantity, required documents such as EN 10204 3.1 material test reports, inspection, packing and marking, Incoterm with named place, delivery date and offer validity. Every missing field becomes a question, an assumption or a price difference. ## What is an RFQ and what is it for? **RFQ (request for quotation)**: A document sent to suppliers asking for a price, delivery time and commercial terms for a defined item to a defined specification. An RFQ has two jobs. It lets each supplier quote the same scope, and it gives the buyer offers that can be compared line by line. Both jobs fail when the item description is loose. Write the RFQ so that two suppliers reading it independently would quote the same product. ## What must you specify for each item? Use one line per item, with the same fields in the same order. For piping materials, the fields below cover most requests. **Item fields for an industrial materials RFQ** | Field | What to state | Example | | --- | --- | --- | | Item | Product type and form | Pipe, seamless; flange, weld neck; elbow, 90° long radius | | Size | NPS (nominal pipe size) or DN, plus length or dimensions | NPS 6; 6 m lengths | | Schedule or class | Wall thickness schedule or pressure class | SCH 40; Class 300 | | Material grade | Specification and grade | ASTM A106 Gr. B; ASTM A182 F316L | | Dimensional standard | The standard governing dimensions and tolerances | ASME B36.10M; ASME B16.5; ASME B16.9 | | Ends and facing | End preparation or flange face | Beveled ends; raised face (RF) | | Quantity and unit | Number, length or weight with its unit | 120 m; 20 pieces | | Special service | Sour service, low temperature, impact testing, supplementary requirements | NACE MR0175 / ISO 15156; impact tested | The examples show format only. Choose grade, schedule and class from your design basis. A complete line reads like this: **Pipe, seamless, NPS 6, SCH 40, ASTM A106 Gr. B, ASME B36.10M, beveled ends, 120 m.** Always name the edition of each standard, or state “latest edition at the date of this RFQ”. Standards change, and the edition can change a requirement. ## Which documents should the RFQ require? List the documents in the RFQ, not after the order. Suppliers price documentation and some cannot supply certain types. - **Material test reports (MTRs).** State the type under EN 10204, for example 3.1. Ask for one certificate traceable to each heat number. The guide [Material test reports explained](https://jjprojectsok.com/knowledge/material-test-reports) covers the types. - **Conformity statements.** For example a declaration of conformity to the product specification. - **Test records.** Hydrostatic, impact, hardness or NDT records when the specification requires them. - **Manufacturer data books.** For equipment, the drawings, procedures and records you need at handover. - **Certificate of origin**, if your import process needs it. If the material is for sour service, say so and name the governing standard (NACE MR0175 / ISO 15156). It limits hardness and affects grade choice. ## How do you specify inspection and testing? Say what will be inspected, by whom and where. A statement such as “third-party inspection at the manufacturer's works before shipment” is enough for the supplier to price it. - Inspection agency, if you name one, and the point of inspection - Positive material identification (PMI), with the percentage of items to be checked - Witnessed or non-witnessed tests - Release rule: no shipment without inspector release If you leave inspection out of the RFQ and add it to the PO, expect a price change and a schedule change. ## What do packing and marking requirements look like? State how the goods must be protected and identified for the route they will travel. Export packing for sea freight differs from domestic road delivery. - Packing type: wooden crates, pallets, bundles, end caps, flange-face protectors - Protection against corrosion for sea transport - Marking on each item or bundle: material grade, size, heat number, PO number - Packing list with item, quantity, weights and dimensions Marking that matches the MTR lets the receiving party trace each item to its certificate. ## Which commercial terms belong in the RFQ? Commercial terms make offers comparable. Without them, one supplier quotes ex works and another quotes delivered, and the price gap means nothing. **Commercial fields** | Field | What to state | | --- | --- | | Incoterm and named place | Incoterms 2020 rule plus the exact place, for example “FCA Houston, Texas” or “DAP [your plant], city, country” | | Delivery date | Required date at the named place, and whether partial shipments are accepted | | Offer validity | How long the price must remain open, stated in days | | Currency and payment terms | Quotation currency and your standard payment terms | | Response date | Date and time offers are due, and the contact for questions | | Exceptions | Ask suppliers to list every deviation from the RFQ in a separate section | The guide [Incoterms 2020 explained](https://jjprojectsok.com/knowledge/incoterms-2020) shows how each rule changes who pays and who carries risk. ## What are the most common RFQ mistakes? - Naming the NPS and omitting the schedule or class - Naming a specification without a grade (ASTM A106 covers Grades A, B and C) - Asking for “certificates” without saying which type - Leaving the delivery basis open - Mixing metric and imperial dimensions in one line - Not saying whether alternates are acceptable Decide in advance whether equivalent grades are allowed. If they are, list which ones. If they are not, say “no alternates”. ## How can JJ Projects help?

One: the requirement. Scope, specification and quantities are defined and approved. Two: the request for quotation goes to qualified vendors with a clear deadline. Three: vendors return priced quotations against the same scope. Four: evaluation compares technical and commercial compliance side by side. Five: the award selects the compliant offer and records the decision. Six: the purchase order commits scope, terms and delivery in writing. Seven: expediting checks progress against the delivery schedule. Eight: inspection verifies the material against the order before it ships. Nine: shipment, with documents and logistics following the agreed Incoterm. Ten: delivery to site, where the goods are received and checked against the order. The illustrations are generic pictograms of the process. ## Questions ### What information is mandatory in an RFQ? At minimum: the item, size, schedule or class, material grade, governing standard and edition, quantity, required documents, Incoterm with named place, delivery date and offer validity. Suppliers can quote without guessing only when all of these are present. ### Should an RFQ include a target price? No. An RFQ asks for the supplier's price against your specification. A target price can reduce the information you get and has no place in a technical description. ### What is the difference between NPS and DN in an RFQ? NPS is the North American nominal pipe size in inches; DN is the metric equivalent. NPS 4 corresponds to DN 100. State one system and keep it throughout the RFQ. ### How long should offer validity be? Set it to cover your evaluation and approval time, and state it in days. Metal prices and manufacturer capacity can change, so suppliers often quote shorter validity than buyers expect. ### Can I send the RFQ as a spreadsheet? Yes. A spreadsheet with one row per item and one column per field is the easiest format to quote and to compare. Attach the referenced specifications and send the same file to every supplier. ## Sources - [ICC, Incoterms 2020 rules](https://iccwbo.org/business-solutions/incoterms-rules/incoterms-2020/) - BS EN 10204:2004, Metallic products: types of inspection documents - ASME B36.10M and B36.19M, pipe dimensions and schedules - ASME B16.5, Pipe Flanges and Flanged Fittings - NACE MR0175 / ISO 15156, materials for use in H2S-containing environments in oil and gas production ## Related - [Procurement](https://jjprojectsok.com/services/procurement): Sourcing from manufacturers and authorized distributors, technical and commercial evaluation, purchase-order follow-up, inspection and delivery coordination. - [Steel and structural](https://jjprojectsok.com/products/steel-structural): Carbon, alloy, stainless and copper plate, sheet, line pipe, process tubing, forgings, flanges, fittings, bolting, gaskets and structural steel for industrial projects. - [Request a quote](https://jjprojectsok.com/request-a-quote): Request a quotation for steel, valves, refractory, electrical, safety or IT supply, or for engineering and project management.
