What is NRE or tooling on a CNC quote?

NRE (non-recurring engineering) covers one-time costs: CAD/CAM programming, custom fixtures or soft jaws, and sometimes special cutting tools. Pure CNC machining usually has low or no hard tooling, unlike injection molding or casting. It's charged once, not per part.

What do EXW, FOB and DDP mean on a quote?

They are Incoterms defining who pays and is responsible for shipping at each stage. EXW (Ex Works) means you arrange everything from the factory door; FOB means the seller gets goods onto the vessel; DDP (Delivered Duty Paid) means the seller delivers to you with duties paid. A low EXW price plus shipping and duties can exceed a higher DDP price, so compare on the same basis.

What should I check before accepting a CNC quote?

Confirm the material grade, the tolerances quoted, the surface finish, the Incoterm and what it includes, the lead time, the inspection provided, and the payment terms. Make sure two quotes you compare cover the same scope before judging on price.

Q: Why does the unit price drop so much at higher quantities?

Most of a CNC part's cost is one-time setup: programming, fixturing and first-article checks. That fixed cost is spread across the batch, so 100 pieces cost far less each than 1. This is why a single prototype can look expensive per piece while production volumes look cheap.

Why the Headline Price Lies

A CNC quote is rarely one number. The "cheap" quote often hides setup costs in a high minimum quantity, or quotes EXW so shipping and duties land on you later. The "expensive" one might be DDP with inspection included. You can only compare quotes line by line — so here's what each line means.

Batch of CNC machined aluminium brackets showing how unit cost drops with quantity — EKINSUN — The quantity effect in practice: this batch of aluminium brackets — 20 pieces — cost 40% less per unit than a 1-piece run. The setup time is the same; it spreads over more parts.

The Line Items, Explained

Line	What it is	Negotiable?
Unit price	Per-piece machining cost; drops sharply with quantity	Yes, via quantity / design tweaks
Setup / NRE	One-time programming, fixturing, first-article	Amortised over the batch
Tooling	Custom jaws or special cutters (often low for CNC)	Sometimes waived at volume
Material	Stock cost; varies a lot by grade	Yes — grade choice matters
Finish / coating	Anodize, plate, blast, etc.	Yes — drop if not needed
Inspection	CMM / dimensional report	Worth keeping
Incoterm	EXW / FOB / DDP — who pays freight & duty	Compare on the same basis
Lead time	Working days to ship	Express often available for a fee
MOQ	Minimum order quantity	See MOQ explained
Payment terms	Deposit %, balance trigger	Staged terms are normal & safer

The Quantity Trick — and Why It's Real Physics, Not a Scam

If one piece costs $90 and a hundred cost $12 each, that's not price gouging — it's the setup being spread across the batch. Programming, fixturing and the first-article check are paid once whether you make 1 or 100. Understanding this lets you ask the right question: "what quantity gets the unit price I want?" rather than assuming the prototype price is the production price.

Compare on the Same Basis

Same Incoterm — an EXW price plus freight and duty can beat or lose to a DDP price; normalise them.
Same tolerances and finish — a cheaper quote machining to looser tolerances isn't the same part.
Same inspection — "with CMM report" vs "no inspection" is a real cost difference.
Same quantity and MOQ — make sure both quotes are for the order you'll actually place.

Red flag: a quote with no breakdown, 100% payment up front to a personal account, and no inspection offered. Before you commit, it's worth knowing how to vet the shop behind the number.

Parts That Illustrate Common Quote Line Items

Parts where setup cost, material cost and surface finish each played a significant role in the quote breakdown:

CNC machined custom fasteners bolts and spacers — material choice affects quote price — Fastener assortment: same geometry in steel vs. stainless vs. brass — three very different quotes. Material is often the biggest cost variable.

Brass fittings in blister tray — packaging cost added to quote for export shipment — Blister-tray packaging is a quote line item: added for export orders requiring retail-ready presentation.

EKINSUN QC room — inspection cost sometimes quoted separately for precise parts — QC inspection: CMM report, FAI, and AQL sampling each add to quoted cost. Ask which level applies to your order.

Frequently Asked Questions

Most cost is one-time setup — programming, fixturing, first-article — spread across the batch. So 100 pieces cost far less each than 1.

NRE covers one-time programming, custom fixtures and special tools. CNC usually has low or no hard tooling, charged once, not per part.

Incoterms defining who pays freight and duty. EXW = you arrange everything from the door; FOB = seller loads the vessel; DDP = seller delivers with duties paid. Compare quotes on the same Incoterm.

Material grade, tolerances, finish, Incoterm and inclusions, lead time, inspection and payment terms — and that two compared quotes cover the same scope.
