What the line items on a Chinese supplier quotation actually mean, the red flags that signal a bad quote, and how to compare multiple quotes fairly.
A quote from a Chinese electronics factory looks nothing like a quote from a Western contract manufacturer. The line items are different, the terminology is different, and the things that matter are buried or missing entirely. Here's how to read one without getting surprised later.
Why Chinese factory quotes look the way they do
Most Chinese electronics factories built their quoting process around domestic buyers who already understand the conventions. When they quote international buyers, they often use the same format — which means a Western buyer gets a document that assumes knowledge they don't have.
The other factor is that many quotes are produced by salespeople, not engineers. The sales contact knows the price they're supposed to hit; they may not fully understand the cost structure behind it. That gap creates quotes that are internally inconsistent in ways that only become visible when you ask the right questions.
The standard line items, and what they actually mean
Unit price is the per-piece cost at the stated quantity. This number is almost always quantity-dependent — a factory should be showing you price breaks at different volumes (e.g., 500 pcs / 1,000 pcs / 3,000 pcs). If you receive a quote with a single unit price and no quantity breakpoints, that's either an oversight or a signal that the factory doesn't want to show you how much their margins drop at volume.
Tooling fee (sometimes listed as "mold fee" or "NRE — non-recurring engineering") covers one-time costs to produce tooling specific to your product: injection molds for plastic enclosures, die-cast parts, custom metal stampings, or sometimes PCB stencils. This cost is not amortized into the unit price by default — it's a separate up-front charge. A typical single-cavity plastic enclosure mold runs $3,000–8,000. A more complex multi-cavity mold is $10,000–25,000. These numbers should be itemized, not bundled into a vague "setup fee."
Sample fee is what you pay before production to receive prototype or pre-production samples. Sample fees are often waived or credited against the first production order — but not always, and the terms should be explicit. If a quote says "samples free" with no context, ask whether that's free-of-charge or credited toward the order.
Shipping term tells you where the factory's financial and legal responsibility ends. The three you'll encounter most:
- EXW (Ex Works): factory packs the goods and your responsibility starts at the factory gate. You arrange freight, insurance, export customs clearance, and everything after. This gives you the lowest quoted price but also the most responsibility.
- FOB (Free On Board): factory delivers goods to the named port and loads them onto the vessel. This is the most common term for China export, and it's the right baseline for most comparisons.
- CIF (Cost, Insurance, Freight): factory arranges and pays for freight to your destination port. Sounds convenient, but you lose visibility into freight costs, and factories often mark up the logistics.
Payment terms specify how and when you pay. The standard for first-time orders is 30% deposit, 70% balance before shipment (sometimes written as "30/70 T/T"). Established relationships sometimes move to Net 30 or 30% / 70% after Bill of Lading. Payment terms that skip the balance-before-shipment step are a risk you shouldn't take until the relationship is well established.
Red flags in quotes
A single unit price with no quantity breakpoints. Every factory has a cost structure that changes with volume. If they won't show you the curve, they're either withholding information or they don't know it — neither is good.
"Approx." or "TBD" on tooling costs. Mold and tooling costs should be quotable before production starts. "Approximately $5,000" on a mold that turns out to cost $9,000 is a common source of disputes. If the factory genuinely doesn't know yet, they need to tell you why and when they will — not give you a placeholder.
No shipping term stated. A unit price without a stated shipping term is meaningless for comparison purposes. EXW $12.50 and FOB Shenzhen $13.20 are not directly comparable — the FOB price includes export clearance and port handling that EXW doesn't. Always ask for the term to be explicit.
No payment terms stated. A quote that specifies price but not payment terms is incomplete. You should know before you negotiate whether they expect 50% upfront or 30/70.
Bundled "other fees." Watch for a line that says something like "packaging, inspection, and documentation: $XX." Each of those should be itemized. Inspection fees in particular vary enormously — a factory doing a basic visual check is very different from one using AOI and functional test fixtures.
How to compare multiple quotes fairly
When you have quotes from three factories, they're almost never directly comparable out of the box. Here's how to normalize them:
Separate NRE costs from unit cost. Tooling, mold fees, and sample fees are one-time costs that don't repeat on subsequent orders. Calculate a total-cost-of-ownership for your first order (unit cost × qty + NRE), and a recurring cost for reorders (unit cost × qty only). A factory with higher unit cost but lower mold fees may be cheaper over two or three orders.
Normalize to the same shipping term. Convert everything to EXW or FOB from the same port. Ask each factory for their EXW price if some quoted FOB, or vice versa. Don't compare an FOB Shenzhen price directly to an EXW Dongguan price without adjusting.
Verify quantity assumptions. Make sure all quotes are priced at the same quantity. A quote at 1,000 units from one factory and 500 units from another isn't a price comparison — it's two different numbers.
Check what's included in unit price. Some factories include packaging; others quote packaging separately. Some include a basic function test; others don't. These differences need to be equalized before you compare the numbers.
What to do when you don't understand a line item
Ask the factory to explain it. The explanation is often as informative as the number itself.
A factory that can clearly explain why their tooling fee is $6,500 — "single-cavity mold for your enclosure in P20 steel, 50,000-shot lifespan, includes two rounds of revision" — is one that knows what they're doing. A factory that responds with "standard charge" or a vague explanation of the item you asked about has a cost structure their sales team doesn't fully understand.
Ambiguity in quotes tends to become expensive disputes after you've committed to an order. The questions you ask before signing a PO are free. The questions you ask when there's a dispute over tooling costs are not.
What good quotes look like in practice
A well-structured quote will show unit prices at 2–3 quantity tiers, line-item NRE costs with brief descriptions, a clearly stated shipping term, payment terms, lead time, and a validity period (typically 30 days for component pricing). If any of those are missing, ask before negotiating on price — you may be comparing incomplete information.
For help evaluating suppliers before you're committed to an order, see our Sourcing & Supplier Matching service. For what to verify once you've selected a factory, our Factory Audit Checklist covers the on-the-ground verification process. A realistic example of how quote evaluation feeds into supplier selection is documented in the EU startup Bluetooth speaker case, where three factory quotes were normalized and compared before the audit and sample phases. For consumer electronics products specifically, understanding what's included in unit pricing is especially important given the range of certification and packaging requirements in that category.
