The Complete Guide to Circular Knitting Machine RFQs: How to Request, Compare & Negotiate Quotations (2026)

A circular knitting machine costs anywhere from $18,000 to $70,000 depending on configuration. That’s a capital decision most textile factory owners make once every 5-10 years. Getting the RFQ (Request for Quotation) process right — or wrong — directly impacts what you pay, what you get, and how long it takes to arrive.

This guide covers the entire RFQ workflow for circular knitting machines: what to include in your request, how to compare competing quotes, common traps that inflate costs, and how to negotiate terms that protect your investment.

What an RFQ Must Include for Circular Knitting Machines

A vague RFQ gets vague quotes. Suppliers will fill in the blanks with their most profitable configuration, not the one that fits your production needs. Every RFQ for circular knitting machines should specify these parameters:

Technical Specifications

Machine type and configuration:

Single jersey, double jersey, or jacquard
Asian style (open cam) vs. European style (closed cam)
Open-width or tubular output

Gauge and diameter:

Gauge: measured in needles per inch (e.g., 24G, 28G). Higher gauge = finer fabric
Diameter: measured in inches (e.g., 30″, 34″, 38″). Determines maximum fabric width
Number of feeders: directly impacts production speed. A 30″ diameter single jersey typically has 72-96 feeders

Speed and output:

Cylinder speed (RPM): standard is 25-35 RPM for single jersey
Daily output target (kg/day): helps suppliers size the machine correctly

Control system:

Display panel type (touch screen vs. button control)
Brand preference for key components: servo motors (Yaskawa, Mitsubishi, Delta), electronic yarn feeders, take-down systems

Power requirements:

Voltage and phase (220V/380V, single or three-phase)
Total power consumption (kW)

Commercial Terms to Specify

Beyond technical specs, your RFQ should clearly state:

Delivery terms: FOB Shanghai, CIF [your port], or EXW factory
Payment terms: 30% deposit + 70% before shipment is standard. Some suppliers accept LC at sight for orders above $50,000
Lead time: Expected delivery date from order confirmation
Warranty period: 12 months is standard; negotiate 18-24 months for critical components
After-sales support: Installation supervision, training, spare parts availability
Inspection requirements: Pre-shipment inspection by third party (SGS, Bureau Veritas) or buyer’s own team

How to Structure Your RFQ for Accurate Quotes

Send your RFQ to at least 3-5 suppliers simultaneously. Fewer than three means you have no basis for comparison. More than five creates noise — suppliers spend less time on RFQs when they know they’re one of many.

RFQ Format That Works

Use a structured table format for technical specifications. This forces suppliers to respond point-by-point instead of sending a generic brochure with a price slapped on top.

Example RFQ structure:

Parameter	Requirement
Machine type	Single jersey, Asian style
Diameter	30 inch
Gauge	24G
Number of feeders	96
Cylinder speed	30 RPM max
Control system	Touch screen, Chinese or Japanese servo
Output	150-200 kg/day (single jersey plain)
Delivery terms	CIF Nhava Sheva, India
Payment	30% T/T advance, 70% before shipment
Warranty	12 months
Lead time	≤90 days from deposit

Attach a separate page for commercial terms and any special requirements (custom color, specific component brands, packaging for sea freight).

What to Request Alongside the Price

Ask suppliers to break down their quote into:

Base machine price
Optional extras: Additional feeders, upgraded servo motors, jacquard attachment
Standard spare parts kit: Needles (1 set), sinkers (1 set), cams (1 set), yarn feeder spare parts
Installation and commissioning: On-site supervision (usually 5-10 days, buyer covers travel)
Documentation: Operation manual, electrical diagrams, spare parts list — all in English

Without this breakdown, you’ll get a single number that looks competitive until you realize the spare parts kit, installation, and upgraded components are all extra.

Comparing Quotes: What Actually Differs

When quotes arrive, most buyers sort by price and start negotiating with the cheapest. That approach misses the real differences between suppliers.

Key Comparison Dimensions

Component sourcing:

The same “single jersey 30-inch 24G” machine can vary by $8,000-$15,000 based on component quality. Ask each supplier to list the origin of:

Servo motors (Japan vs. China: $500-800 difference per motor)
Bearings (SKF/FAG vs. Chinese brands: affects lifespan by 2-3 years)
Needle brand (Groz-Beckert, Starlight, or generic)
Control system (proprietary vs. standard PLC)

Production capacity and backlog:

A supplier quoting 30-day delivery with a 6-month backlog is actually quoting 6+ months. Ask for current production schedule and confirm the lead time in writing with a penalty clause for delays.

Testing and quality control:

Reputable suppliers run each machine for 24-72 hours before shipping, producing test fabric. Ask for:

Test fabric photos/videos
Noise level readings (should be below 80 dB for standard machines)
Vibration measurements
Electrical safety test reports

After-sales track record:

Request contact information for 3 recent buyers in your region. Call them. Ask about spare parts delivery speed, technical support responsiveness, and any issues in the first year.

Common RFQ Mistakes That Cost Buyers Money

1. Not Specifying Fabric Type and Yarn

A machine quoted for producing single jersey plain fabric may struggle with single jersey lycra if the yarn feeder and take-down system aren’t designed for elastic yarns. Always state:

Primary fabric types you’ll produce
Yarn types (cotton, polyester, lycra, blends)
GSM range of target fabrics

2. Ignoring the Spare Parts Ecosystem

Some manufacturers use proprietary needle and sinker profiles. If the supplier goes out of business or discontinues the model, you’re locked into a single source for consumables. Ask:

Are needles/sinkers compatible with standard profiles (Groz-Beckert, Starlight)?
What’s the typical lead time for spare parts orders?
Do you maintain spare parts inventory for machines 10+ years old?

3. Accepting the First Quote as Baseline

Suppliers in China typically have 15-25% margin built into initial quotes. The first number is rarely the best number. Use competing quotes as leverage — share the lowest price (anonymized) and ask if they can match or beat it.

4. Skipping the Pre-Shipment Inspection

Approximately 15-20% of machinery shipments from China have some form of specification deviation — wrong gauge needles installed, different servo motor brand, missing accessories. A pre-shipment inspection ($300-500 for a third-party inspector) catches these before the machine leaves the factory.

Negotiation Levers That Actually Work

Volume and Repeat Orders

If you’re buying multiple machines (even across different orders), mention it. Suppliers offer 5-10% discounts for orders of 3+ machines, and better payment terms for repeat buyers.

Payment Terms as Leverage

Offering 50% upfront instead of 30% gives suppliers better cash flow. Some will discount 2-3% for higher advance payments. Conversely, if you can provide an irrevocable LC at sight, that’s also valuable to suppliers and can be negotiated for better pricing.

Off-Season Ordering

Chinese manufacturers have slower periods around Chinese New Year (January-February) and the summer months (July-August). Placing orders during these windows can shave 5-10% off the price and reduce lead times since factory capacity is available.

Component Substitution

If a supplier quotes Japanese servo motors but you’re open to high-quality Chinese servos (Delta, Inovance), the savings can be $2,000-$4,000 per machine with minimal performance difference for standard fabrics.

From RFQ to Delivery: The Full Timeline

Understanding the end-to-end process helps you plan production and avoid costly delays.

Week 1-2: Send RFQ to 3-5 suppliers. Follow up within 3 business days if no acknowledgment received.

Week 2-4: Receive and compare quotes. Request clarifications. Negotiate terms. Visit top 2 suppliers if possible (or hire a local inspection company for a factory audit).

Week 4-5: Select supplier and sign purchase contract. Pay deposit (typically 30%).

Week 5-14: Manufacturing period. Request progress photos at the 50% and 80% completion marks.

Week 14-15: Pre-shipment inspection. Pay balance (70%). Arrange shipping.

Week 15-19: Sea freight (varies by destination: 15-30 days to most ports). Customs clearance.

Week 19-20: Delivery to your factory. Installation and commissioning (5-10 days).

Total timeline from deposit to production: approximately 4-5 months for standard configurations. Add 1-2 months for custom specifications or during peak season (September-December).

Frequently Asked Questions

Q: How many suppliers should I send my RFQ to?

A: 3-5 is the sweet spot. Fewer than three gives you no comparison basis. More than five means suppliers invest less effort per response, knowing the odds are against them.

Q: Should I visit the factory before placing an order?

A: If the order value exceeds $50,000, yes. Factory visits reveal production capacity, quality control processes, and workforce stability that no brochure can. If you can’t visit, hire a third-party inspection company ($500-1,000) to audit the factory and send you a report with photos.

Q: What’s the standard warranty for circular knitting machines?

A: 12 months from shipment date is standard across Chinese manufacturers. Some European-origin components (servo motors, bearings) carry their own manufacturer warranties (typically 18-24 months). Negotiate to extend the overall warranty to 18 months for critical mechanical components.

Q: Can I negotiate after receiving quotes?

A: Absolutely. Initial quotes typically include 15-25% margin. Share competing prices (without naming suppliers) and ask for best and final offers. Most suppliers expect at least two rounds of negotiation.

Q: What payment method is safest for large machinery orders?

A: 30% T/T advance + 70% against copy of B/L (Bill of Lading) is the most common and balanced approach. For orders above $100,000, consider an irrevocable Letter of Credit at sight, which protects both buyer and supplier.

Q: How do I verify a supplier’s claimed production capacity?

A: Ask for their export license records, VAT invoices from the past 12 months, and contact details for recent buyers. Cross-reference with Alibaba transaction records if available. A factory claiming 500 machines/year should be able to show evidence of at least 300+ units shipped.
