A structured, field-tested checklist that helps procurement engineers and supply chain managers prepare a complete RFQ — one that earns an accurate quote within 24 hours instead of a week of follow-up emails. Six information categories, a 15-item self-check table, quote timeline, lead-time factors, drawing specs, and a copy-ready RFQ template.
Every hour spent preparing the RFQ saves at least four hours in the quote cycle. The three causes below account for nearly all quote delays in fine blanking steel procurement.
When an RFQ omits the delivery condition, annual volume, or thickness tolerance, the supplier cannot price the order confidently. Each round of email follow-up adds one to two working days. A typical incomplete RFQ generates 3–5 clarification exchanges before a formal quote can be issued — turning a 72-hour process into a two-week wait.
Fine blanking is a geometry-sensitive process. Without a 2D drawing showing critical dimensions and tolerances, or a 3D STEP model, the engineer cannot evaluate whether the part is fine-blankable, what die clearance is needed, or whether the material thickness matches the part geometry. DFM feedback cannot be issued, and the quote is stuck at a budgetary estimate with a wide price range.
When the grade is written without a standard, the thickness without a tolerance, or the surface without a finish requirement, the supplier prices for the worst-case interpretation. A vague RFQ for "SAE1078 strip" may be quoted at a premium because the supplier assumes custom spheroidizing, tight tolerance, and special packaging — when the buyer actually wanted standard stock material. The result is a quote that is 15–30% higher than necessary, and a negotiation cycle that could have been avoided.
The fix is straightforward: prepare the RFQ once, completely, using the six-category checklist below. A complete RFQ reaches the engineering desk ready for immediate assessment. The supplier does not need to guess, follow up, or pad the price. The quote comes back faster, narrower, and closer to the final production price.
Work through all six categories before sending the RFQ. Each category is independent — missing any one of them will trigger a follow-up question and delay the quote.
For material grade selection, refer to the fine blanking material selection guide for a 5-step framework. For spheroidized annealing requirements, see the spheroidizing annealing complete guide. If you are unsure about MTC interpretation, the mill test certificate reading guide explains every field on an EN 10204 3.1 certificate.
Run through this table before you hit send. Each row tells you whether the item is mandatory, what happens if it is missing, and how to fill it in correctly. Score your RFQ at the bottom.

Understanding the quote timeline and the factors that drive production lead time helps you set realistic expectations and plan your procurement schedule.
| Stage | Time | Deliverable | Required input |
|---|---|---|---|
| RFQ receipt & triage | 0–4 h | Acknowledgment email; RFQ assigned to sales engineer | Complete RFQ with all six categories |
| Preliminary quote | ≤ 24 h | Budgetary price range, stock availability check, estimated lead time | Grade, dimensions, volume, delivery condition |
| DFM feedback | ≤ 48 h | Manufacturability assessment, die feasibility, material recommendation, risk flags | 2D drawing + 3D STEP, critical dimensions, tolerances |
| Formal quote | ≤ 72 h | Fixed unit price, MOQ, lead time, sample plan, payment terms, validity | All above + confirmed commercial terms |
| Sample submission | 7–21 days | Physical sample with MTC, dimensional report, surface inspection | Signed quote, sample PO, deposit if required |
Timeline assumes a complete RFQ received during working hours (China Standard Time, UTC+8). Incomplete RFQs add 1–2 working days per follow-up round. Holidays (Chinese New Year, National Day) may extend the timeline by 3–7 days.
| Factor | Impact level | How to optimize | Typical delay |
|---|---|---|---|
| Material stock availability | High | Order standard stock sizes; provide 2–3 grade alternatives; plan orders 4–6 weeks ahead | +10–20 days |
| Custom width slitting | Medium | Use standard slit widths (100, 125, 150, 200 mm); order full-width coil and slit in-house | +3–7 days |
| Spheroidizing annealing cycle | High | Plan for 12–18h furnace cycle + cooling; batch multiple orders; avoid peak season (Q4) | +7–12 days |
| Surface treatment | Medium | Use mill finish + oil for standard; polished/bright finish adds processing; avoid custom coatings | +3–10 days |
| Inspection & packaging | Low | Standard MTC 3.1 + coil packaging is fastest; 3.2 third-party inspection adds scheduling time | +1–5 days |
| Order type | Production | Logistics (sea) | Total lead time | Typical application |
|---|---|---|---|---|
| Stock size (standard grade & dimensions) | 1–3 days | 25–35 days | 3–7 days (EXW) / 30–40 days (CIF) | Prototypes, urgent spare parts, small batch trials |
| Custom slit width (stock grade) | 5–10 days | 25–35 days | 7–15 days (EXW) / 35–50 days (CIF) | Progressive die feed stock, medium volume production |
| Spheroidized annealed (custom) | 12–20 days | 25–35 days | 15–25 days (EXW) / 45–60 days (CIF) | Fine blanking production, high-carbon grades, clutch plates |
| Special grade (mill order) | 25–35 days | 25–35 days | 30–45 days (EXW) / 60–80 days (CIF) | Rare alloys, custom chemistry, large volume annual contracts |
All lead times are typical reference values, confirmed per order based on actual mill availability, order queue, and logistics conditions. Sea freight times are for Shanghai → Europe / US East Coast. Air freight reduces logistics to 5–7 days but costs 4–6x more.
Drawings are the single most important technical document in an RFQ. A well-annotated drawing eliminates 80% of follow-up questions. This section specifies exactly what to include.
For fine blanking applications, the drawing must also specify the shear face quality requirement. A fine blanked part typically requires 100% clean shear face with no fracture zone — this is different from conventional blanking where 10–30% fracture zone is acceptable. Mark the shear face requirement on the drawing with a note such as "Fine blanked surface: 100% shear, Ra ≤ 1.6 µm, no fracture zone." See the fine blanking seat recliner application page for real drawing examples.
Copy the template below into your email client, fill in the placeholders, and attach your drawings. The two worked examples show how a completed RFQ looks for real production parts.
This template is designed for plain-text email clients. Copy the entire block, replace bracketed placeholders, and attach drawings. Do not convert to HTML or rich text — plain text ensures the supplier's system parses every field correctly.

Part function: Circular saw blade body for wood cutting. The blank is fine blanked to a 250 mm OD disc with 40 teeth, then quenched and tempered to 45–50 HRC, then ground and Teflon-coated. Flatness after heat treat is critical — the blade must run true without wobble.
Drawings: 2D PDF Rev. B attached. Critical: OD 250.0 ±0.05 mm, ID 25.4 H8, flatness 0.08 mm, tooth profile per DIN 1837 B. 3D STEP: SB-2024-003_RevB.stp. Edge condition: rounded (deburred) slit edge, burr ≤ 0.02 mm. Shear face: 100% clean shear on tooth profile.
Quality: ISO 9001 certified. MTC EN 10204 3.1 per coil. Additional: 100% flatness inspection per coil, surface inspection per AQL 1.0. Packaging: 2,000–3,000 kg coils, ID 508 mm, interleaved with anti-scratch paper, wooden pallet with corner protectors.
Logistics: CIF Los Angeles, USA. Required delivery: first batch by 2026-12-15. Sea freight FCL 20ft. Split delivery: no — full annual volume in 10 batches over 12 months, call-off 4 weeks ahead.
Commercial: 30% T/T deposit, 70% L/C at sight. USD. Quote validity 90 days. Target price: ≤ USD 1.85/kg (CIF LA). NDA: not required — standard saw blade geometry.
Why this RFQ works: The bright polished surface and dry (no oil) requirement are explicitly stated — these are non-standard and affect price by 10–15%. The flatness requirement in I-units is measurable and specific. The rounded edge condition is specified (standard slit edge would be unsuitable for a saw blade body). The target price gives the supplier a clear budget. The call-off schedule allows the mill to plan production efficiently.

These five mistakes account for the majority of follow-up emails and quote delays. Each is shown as a wrong entry followed by the corrected version.
A grade name without a standard is ambiguous. SAE1078 can be supplied under ASTM A109 (cold-rolled), ASTM A568 (hot-rolled), or GB/T 711 (Chinese standard) — each has different chemistry ranges and tolerance classes. Always cite the standard and key chemistry limits.
Without a tolerance, the supplier assumes the tightest available (±0.02 mm), which costs 15–25% more than standard tolerance (±0.05 mm). If your process can accept standard tolerance, say so — it directly reduces the price.
"Soft" is subjective. A supplier may quote cold-rolled strip at ~220 HB (cheaper) when you need spheroidized at ~180 HB (essential for fine blanking). The result: material arrives, tears in the die, and the dispute takes weeks. Always specify the condition and a measurable hardness band.
A one-time 1,000 kg order is quoted at MOQ / small-batch pricing (premium 20–40%). If this is a recurring annual volume, the supplier can offer a volume-tier price and reserve mill capacity. Always state both the first batch and the annual forecast.
A drawing without critical dimension flags forces the supplier to assume every dimension is critical — which drives up the process cost and the quote. Mark only the truly critical dimensions (usually 3–5 per part) and let the rest fall under general tolerance. This gives you the lowest price that still meets functional requirements.
Your drawings and product specifications are valuable IP. This section explains how we protect them and what you can do to keep them secure during the RFQ process.
For initial budgetary quoting, you do not need to send drawings. Send the material specification (grade, dimensions, volume, delivery condition) and we can provide a price range within 24 hours. Once you are ready to move to formal quoting and DFM, execute the NDA and send the full drawing package. This two-stage approach protects your IP while still giving you fast pricing information.
