Reading a CNC quote, line by line.

A proper CNC quote — the kind that avoids surprises — should contain these 10 lines. If any are missing, ask before signing the PO:

The unit price is never a single number. It's a function of quantity. A good quote shows price breaks:

The unit price typically drops 20–50% from prototype quantity to production — reflecting amortized setup time and batch efficiency.

Red flags:

• Same price at all quantities — supplier hasn't actually priced for scale. Either they're a trader passing through to a factory, or they'll surprise you later.
• Dramatic drops at small quantities — e.g., $80 at qty 5, $25 at qty 10. Suggests $75 of pure setup is being amortized across the first few parts. Ask about setup charge explicitly.
• Missing price breaks entirely — if you're buying 500 parts, insist on seeing the 1,000 and 5,000 unit prices, even if you don't plan to order them. Tells you how much room there is in the unit price.

MOQ in CNC is different from MOQ in injection molding or castings. CNC has no tooling, so MOQ isn't about amortizing a mold. It's about the supplier's minimum economically viable batch.

Typical CNC MOQs:

• Prototype shops (Protolabs, Hubs-style): MOQ = 1
• Mid-volume shops: MOQ = 10–50
• Production-focused shops: MOQ = 100+

If a quote says "MOQ: 500" and you need 50, it doesn't mean the supplier won't make them — it means they'll charge a setup premium. Ask for the MOQ-waived price at your actual quantity.

Non-recurring engineering (NRE) and setup charges cover:

• CAM programming (converting your STEP into toolpath instructions)
• First-article inspection program creation
• Fixturing design if needed
• Initial material staging, tool changeouts, machine calibration

Typical NRE for CNC parts:

If NRE is hidden: some suppliers bury NRE in the unit price instead of listing it separately. At low quantities, the unit price looks high; at high quantities, it looks suspiciously cheap. Ask explicitly: "If I order this same part again in 6 months with no changes, what's the re-run price?" That price is the true marginal unit price minus NRE amortization.

CNC rarely needs dedicated tooling (that's what separates it from injection molding or stamping). But custom fixtures are sometimes required — especially for:

• Thin-walled or delicate parts needing custom holders
• Parts machined on multiple sides requiring indexing jigs
• Very small or awkward geometries needing vacuum or custom clamp plates
• High-volume production where soft-jaws save setup time per run

Typical fixture cost: $150–$1,200 depending on complexity. Usually one-time, amortized across first production run.

What to ask: Is this fixture specifically for my part, or does it become my property? If I reorder, is the fixture reused at no extra cost? Reputable shops say yes — the fixture is yours for future production.

"6061-T6 aluminum" isn't enough on its own. A complete material line includes:

• Alloy and temper: 6061-T6, not just 6061
• Source: from mill stock or certified to AMS/ASTM specification
• Documentation: Material Test Report (MTR) available at $5–25 per lot if requested
• Country of origin (matters for ITAR, aerospace, defense)

Cheap quotes sometimes cut corners on material. A "6061-T6" part made from unknown-origin Chinese stock is usually functionally equivalent to US-mill 6061-T6 for most applications — but for aerospace, medical, or specification-sensitive work, the origin matters and should be explicit on the quote.

"Anodize black" is vague. Real finish specs include:

• Type: Type II (decorative, 8–25 μm), Type III (hard anodize, 25–75 μm)
• Color: black is easy, custom colors add $0.50–$2 per part
• Masking: which features, if any, are masked (threads, mating surfaces, datums)
• Coverage: full part or specific surfaces only

A vague quote — "parts to be anodized black" — leaves room for the cheapest-possible Type II anodize, no masking, no seal. For appearance parts or sealed functional surfaces, insist on specifics.

Common finish costs (as % of base part price):

Most quotes include basic in-process inspection (not documented). Enhanced documentation is extra:

If your drawing has ±0.02 mm callouts with no inspection spec, the supplier will assume statistical sampling. Explicitly request 100% measurement if every part must hit tolerance.

Default packaging is "bulk in poly bags, boxed". That's fine for hardware. For anything else, specify:

• Individual poly-bagging (prevents scratches between parts): +$0.10–$0.30 per part
• Foam-cut trays (cosmetic/delicate parts): +$0.50–$2 per part
• Vacuum-sealed with desiccant (rust-prone steel, long transit): +$0.30–$0.80 per part
• Custom labeling per part or per box: +$0.05–$0.20 per part
• Shipping carton specifications (ESD bag? Anti-static foam?): +$5–25 per carton

For medical or regulated parts, packaging is often part of the validated process — specify exactly, including which boxes go into which outer shipper.

A complete quote gives two lead times:

• Prototype / first article: days from PO to samples shipped
• Production: days from PO (after first article approval) to full batch shipped

"Lead time: 3 weeks" without qualification is ambiguous. Does that include FAI approval wait? Does it start from PO or from approved drawing? Does it include shipping?

A clean answer looks like: "Prototype: 10 business days from PO. Production: 15 business days from FAI approval. Excludes shipping transit."

The Incoterm determines where the price quote ends. Four common levels in CNC export:

For the same part, the quotes look very different:

• EXW: $45 per part (freight & duties on you = roughly +$8–15 per part in typical US import)
• FOB: $45 per part + $500 ocean freight at qty 200 = +$2.50 per part, then +$5–10 per part in duties
• DAP: $58 per part (includes freight, no duties)
• DDP: $62 per part (fully landed, nothing else)

When comparing quotes across suppliers, normalize the Incoterms. A "cheaper" EXW quote from one supplier loses its edge once duties and freight are added, vs a DDP quote from another.

Two CNC suppliers quote the same 500-unit aluminum bracket order. Which is cheaper?

Apples to apples: Supplier B (fobproto) costs $7,260 less on this 500-unit order. The FOB-vs-DDP difference alone was $7,000+ because Supplier A looked cheaper per-unit but left out freight and finishing, while Supplier B bundled both.
