An RFQ, or Request for Quotation, is a formal request sent to suppliers to obtain price, availability, delivery time, and technical details for required spare parts.
In industrial maintenance, a good RFQ helps procurement and maintenance teams receive accurate quotations and avoid wrong material supply.
A clear RFQ saves time, reduces supplier clarification, and improves purchasing quality.
What Is an RFQ?
RFQ stands for Request for Quotation.
It is a document or email sent to one or more suppliers asking them to provide a quotation for specific items.
An RFQ usually includes:
- Item description
- Quantity
- Technical specification
- Brand or part number
- Required delivery date
- Delivery location
- Required documents
- Commercial terms
- Contact person
- Deadline for quotation
The more clear the RFQ is, the better the supplier response will be.
Why RFQ Is Important for Spare Parts
Industrial spare parts can be technical and sensitive.
If the RFQ is unclear, the supplier may quote the wrong item.
This can cause:
- Wrong spare parts delivery
- Maintenance delay
- Equipment downtime
- Extra clarification emails
- Rejected materials
- Higher cost
- Emergency purchases
- Production loss
A professional RFQ reduces these problems.
RFQ vs PO
An RFQ is not the same as a PO.
An RFQ is used to request quotation from suppliers.
A PO, or Purchase Order, is issued after the supplier is selected and the purchase is approved.
| Item | RFQ | PO |
|---|---|---|
| Purpose | Request price and offer | Confirm purchase |
| Sent To | Suppliers | Selected supplier |
| Timing | Before purchase approval | After approval |
| Includes | Requirement and quotation request | Final order details |
| Legal/Commercial Status | Request only | Purchase commitment |
Main Information Required in an RFQ
A professional RFQ should include:
- Company name
- RFQ number if available
- Date
- Supplier name
- Contact person
- Item list
- Technical description
- Quantity
- Unit of measure
- Brand or equivalent requirement
- Required delivery time
- Delivery location
- Required documents
- Quotation deadline
- Payment or commercial terms if applicable
- Contact details for clarification
Step 1: Define the Requirement Clearly
Before sending an RFQ, make sure the requirement is clear.
Check:
- What item is needed?
- Why is it needed?
- Is it for replacement, stock, or project?
- Is the exact part number available?
- Is equivalent acceptable?
- Is the item critical?
- Is there a required delivery date?
- Are photos or datasheets available?
Do not send vague requirements to suppliers.
Step 2: Prepare a Technical Description
The technical description is the most important part of the RFQ.
It should include all necessary details.
For electrical items, include:
- Voltage
- Current
- Power rating
- Number of poles
- Coil voltage
- Frequency
- Breaking capacity
- Part number
- Brand
- Accessories
- Application
For mechanical items, include:
- Size
- Material
- Part number
- Pressure rating
- Connection type
- Temperature rating
- Bearing number
- Seal material
- Fluid service
- Equipment model
Step 3: Add Quantity and Unit
Always mention the required quantity and unit.
Examples:
- 2 EA
- 10 MTR
- 1 SET
- 4 PCS
- 20 LTR
- 5 ROLL
Make sure the unit is clear.
For example, “1 SET” should define what is included in the set.
Step 4: Mention Brand or Equivalent
If exact brand is required, mention it clearly.
Example:
“Brand: Siemens only”
If equivalent is acceptable, write:
“Siemens or approved equivalent”
For critical OEM spare parts, equivalent may not be acceptable.
Examples where exact part may be required:
- PLC modules
- VFD control boards
- Soft starter cards
- Compressor OEM kits
- Protection relays
- Special mechanical seals
- Machine-specific sensors
Step 5: Attach Supporting Documents
Supporting documents help suppliers quote accurately.
Attach if available:
- Nameplate photo
- Old part photo
- Datasheet
- Manual page
- Drawing
- Wiring diagram
- Equipment tag details
- Dimension sketch
- Previous PO
- Material code
Photos are very useful when part details are unclear.
Step 6: Define Required Delivery Time
Mention the required delivery time clearly.
Examples:
- Required delivery: urgent
- Required delivery: within 2 weeks
- Required delivery: before 30 March 2026
- Supplier to confirm best delivery time
For critical breakdown items, ask the supplier to mention stock availability.
Step 7: Mention Delivery Location
The RFQ should mention delivery location or site.
Example:
Delivery location:
Eastern Pipes Integrated Company
Dammam, Saudi Arabia
Or simply:
Delivery to buyer warehouse / plant store as per purchase order.
This helps suppliers estimate logistics if required.
Step 8: Request Technical and Commercial Offer
Ask the supplier to submit both technical and commercial details.
The quotation should include:
- Item description
- Brand
- Model or part number
- Quantity
- Unit price
- Total price
- Delivery time
- Warranty
- Country of origin
- Datasheet
- Validity of quotation
- Payment terms if applicable
- Exclusions if any
This makes quotation comparison easier.
Step 9: Set Quotation Deadline
Mention the deadline for quotation submission.
Example:
“Please submit your quotation on or before 15 March 2026.”
This helps control procurement timing.
For urgent items, mention:
“Your urgent quotation is required.”
Step 10: Review Before Sending
Before sending the RFQ, review:
- Item description
- Quantity
- Part number
- Brand
- Attachments
- Delivery requirement
- Supplier list
- Contact details
- Quotation deadline
A short review can prevent many mistakes.

Technical Bid Evaluation
After receiving quotations, maintenance or engineering should review technical compliance.
Check:
- Item description matches requirement
- Part number correct
- Brand acceptable
- Datasheet acceptable
- Ratings suitable
- Dimensions suitable
- Accessories included
- Equivalent technically acceptable
- Warranty acceptable
- Delivery time acceptable
Do not approve a quotation only because it is cheaper.
Commercial Comparison
Procurement may compare:
- Unit price
- Total price
- Delivery time
- Payment terms
- Warranty
- Supplier reliability
- Availability
- Freight charges
- Quotation validity
The best offer is not always the lowest price. It should meet technical and commercial requirements.
Common RFQ Mistakes
Common mistakes include:
- Sending unclear item descriptions
- Missing part numbers
- Missing quantity
- Missing voltage or size
- Not attaching photos
- Not saying if equivalent is acceptable
- No quotation deadline
- No delivery requirement
- Sending RFQ to unsuitable suppliers
- Not reviewing technical compliance
- Selecting wrong item due to price only
Practical Field Example
A maintenance engineer needs a replacement overload relay for a motor starter.
Poor RFQ:
“Please quote overload relay.”
Better RFQ:
“Please quote OVERLOAD RELAY, THERMAL, ADJUSTABLE RANGE 18-25A, SUITABLE FOR SCHNEIDER LC1D CONTACTOR SERIES, MANUAL/AUTO RESET, 1NO+1NC AUX CONTACT, QTY 2 EA, SCHNEIDER OR APPROVED EQUIVALENT.”
This RFQ gives the supplier enough details to quote the correct item.
Tips for Better RFQs
To prepare better RFQs:
- Use clear technical descriptions
- Include part number if available
- Attach photos or datasheets
- Mention application
- Mention quantity and unit
- Define equivalent acceptance
- Ask for delivery time
- Ask for datasheet
- Set quotation deadline
- Review supplier offers technically
Safety and Quality Notes
Wrong spare parts can create safety and reliability risks.
For critical equipment, engineering approval should be required before accepting alternatives.
Always check compatibility before purchasing substitute items.
Conclusion
A professional RFQ helps maintenance and procurement teams obtain accurate quotations for industrial spare parts.
A good RFQ should include clear item descriptions, technical specifications, quantity, brand, part number, equivalent requirement, delivery time, attachments, and quotation deadline.
Clear RFQs reduce wrong deliveries, save time, improve supplier communication, and support reliable maintenance work.
