Same product, five Chinese factories, five quotes back: the lowest at $8, the highest at $24. Is your first instinct “jackpot” on the low one, or “they’re ripping me off” on the high one?
Our answer: hold off on both. A wide spread between quotes isn’t an anomaly — it’s normal in China’s supply chain. The real question is whether you can see where the differences come from — and how to turn a “quote” into a real price.
Drawing on ten years of sourcing-agent experience in Guangzhou, this guide breaks down why five factories quote five different prices, how to write an RFQ that doesn’t invite inflated numbers, and how to compare quotes without falling into low-price traps.
What are the five components inside a factory quote?
Start with one formula: factory quote ≈ material cost + processing cost + overhead + tax + profit. It looks the same on paper; every factory weighs the five parts differently:
| Component | Where the difference comes from | Impact |
|---|---|---|
| Material cost | Same “stainless steel”: 201 vs 304 costs nearly double. Same “plastic”: virgin vs recycled resin runs 30-50% apart | Largest |
| Processing cost | Labor rates, machine age, and yield rates all differ | Medium |
| Overhead | Small factories spread less, big factories manage more; certified factories carry higher overhead | Medium |
| Tax | Tax-inclusive vs tax-exclusive (VAT is usually 13%, refundable on export), whether they can issue special invoices | Medium |
| Profit | High-volume/low-margin vs low-volume/high-margin; direct from factory vs via a trading company | Small–medium |
So the lowest quote may simply mean cheaper materials, a leaner tax treatment, and thinner margins. The price isn’t wrong — what’s wrong is assuming every quote is for the same thing.
Six Real Sources of Quote Differences
1. Different material grades (the most common one)
The classic case in China trade: a customer inquires about “stainless steel.” A Zhejiang factory quotes 3 yuan, a Guangdong factory quotes 6. Neither is wrong — one quoted 201 stainless, the other 304. Writing the exact material grade into your spec is ten times more effective than bargaining.
2. Different readings of your spec
You say “a bit thicker.” One factory reads 1.5 mm, another reads 2.0 mm. Vague specs are a breeding ground for quote gaps. Drawings, dimensions, tolerances, color codes — the more precisely you specify, the closer the quotes get.
3. Different quantity bases
Unit price for 1,000 pcs vs 10,000 pcs can differ 20-30%. Some factories quote on your inquiry quantity, some on “expected order volume,” some at MOQ. Standardize the quantity before you compare.
4. Certification and testing costs — spread in or left out
For categories that need CE, FCC, or UL, factories amortize certification and testing fees differently: some spread them over the first batch, some fold them into unit cost, some leave them out entirely and add them before shipment.
5. Payment terms and lead time
30% deposit vs 100% prepayment. 30-day lead time vs 45 days. Both change the factory’s working-capital cost and production scheduling pressure — and both end up in the price. Factories run the cash-flow math more carefully than you do.
6. Trading company vs factory
Same product: a factory quotes its ex-works price; a trading company quotes a service-inclusive price — inspection, order follow-up, consolidated shipping, and financing are all real costs. A trading company quoting 5-15% above the factory is normal. It isn’t selling the same thing.
How do you write an RFQ that avoids inflated quotes?
Looking at the inquiries that cross our desks, 90% of the ineffective ones look like this: “How much for this?” — no photo, no spec, no quantity.
A factory facing that has two options: quote the highest configuration, or throw out a number to get rid of you. The vaguer your RFQ, the more distorted your quotes.
A proper RFQ contains at least these 8 elements:
- Clear product photos — multi-angle real shots or the manufacturer’s own images, not blurry screenshots
- Specifications — dimensions, material, color (code or Pantone), tolerances, and key metrics like load capacity or power
- Quantity and expected annual volume — long-term business or a one-off?
- Target market — US, EU, or Africa changes certification, packaging, and voltage requirements
- Packaging requirements — retail color box, plain box, or simple export packaging directly changes cost
- Certification requirements — CE/FCC/UL/UKCA must be stated up front
- Target lead time — different lead times mean different scheduling costs
- Quotation terms — FOB at which port / EXW / DDP to where; one Incoterm, or the quotes aren’t comparable
How should you compare quotes by comparing the same thing?
When the quotes come back, do one thing first: lay all five on a single table, line by line — the logic we use for every internal comparison:
| Comparison item | Factory A | Factory B | Factory C |
|---|---|---|---|
| Unit price (uniform FOB basis) | |||
| Tax-inclusive / tax-exclusive | |||
| Material grade / specification | |||
| Certifications included in price | |||
| Packaging | |||
| Lead time | |||
| Payment terms | |||
| Tooling / sampling fees included |
Go through it and you’ll find that most “3x gaps” shrink to 10-20% once the specs line up — the remainder is the genuine market spread.
Also watch for three low-price traps:
- Material switching — quoted on good material, sampled with cheap material, discovered only at mass-production inspection. After comparing, always seal the sample (keep the approved sample on file) and check every production run against it.
- Cut processes — no surface treatment, no inner packaging, no accessories. The quote is 15% lower; fixing it after arrival costs more than you saved. The total cost of importing = unit price + freight + duties + inspection + rework risk + after-sales risk. Unit price is just one line.
- Low price = low accountability — cheap factories often have no after-sales, no QC process, and go silent after shipment.
How do you negotiate a real price in three steps?
Step 1: Probe the floor before you bargain. Using A’s price against B, and B’s against A, is the most common tactic in China trade — but reference only “another supplier’s spec,” never a name, so factories can’t compare notes and raise prices together.
Step 2: Trade volume for price. “If the price gets to X, I can add two more containers this year.” A real volume commitment beats any scripted pitch. But don’t write checks you can’t cash — if a factory discovers your quantity was fiction, every future quote will carry padding.
Step 3: Negotiate a package, not a single number. When the price won’t move, negotiate payment terms (deposit ratio), lead-time flexibility, free samples, or spare parts. A package of concessions closes deals more easily than squeezing one number — and is fairer for both sides.
A realistic expectation: with specs aligned, normal negotiation room is usually 3-8%. If someone quotes 30% below, suspect the spec interpretation first — don’t celebrate.
What does a sourcing agent check at the quoting stage?
You might think: I can send RFQs and compare quotes myself — why pay an agent?
We do all of the above every day, but two things are genuinely hard for an overseas buyer to do alone:
- On-site verification. However clean a quote looks on paper, nothing beats walking the factory — new machines or old, workshop busy or idle, 304 or 201 in the material pile. Ten minutes on site tells you more than ten days of online chat.
- Local negotiating leverage. We have long-standing relationships with Pearl River Delta factories, so we get the local market price — your first inquiry often gets the “tourist price.” A decade of factory database tells us which factory genuinely has the capability in which category, and whose prices are inflated.
So our quoting process is: receive your spec sheet → contact 3-5 matching factories → align specs and compare on a uniform basis → verify factory capability on site → hand you a comparison with real prices and factory profiles. You don’t get five numbers; you get complete profiles of five factories.
FAQ
Q: Tax-inclusive or tax-exclusive price — which should I take?
It depends on your clearance needs. For formal export with customs declaration and VAT refund, take the tax-inclusive price (VAT is usually 13%, refundable on export). For small batches, personal purchases, or courier direct shipment, the tax-exclusive price is more common. Note: if you buy tax-exclusive and your goods hit problems at customs, you handle it yourself.
Q: Why does a trading company quote more than the factory?
Its price includes inspection, order follow-up, communication, consolidated shipping, and after-sales support — the premium buys the time and risk of not dealing with the factory yourself. Don’t compare who’s cheaper — compare whose total cost is lower.
Q: How much is the difference between FOB and ex-works?
FOB = ex-works price + domestic transport + customs clearance + port charges — usually a few tens to a couple of hundred dollars per cubic meter, depending on the port and volume. Ask every factory to quote in the same Incoterm, or the numbers can’t be compared.
Q: How long are quotes usually valid?
In industries with volatile raw materials (hardware, chemicals), quotes typically hold for 7-15 days; stable categories usually 30 days. Reconfirm the price after it expires before you place the order — don’t pay against a three-month-old quote.
Q: How do I tell a real price from an inflated one?
Three checks: ① compare 3+ factories with fully aligned specs; ② ask each factory to itemize “tax-inclusive/exclusive, material grade, packaging, certification, lead time” in the quote; ③ ask for samples or a factory visit — a factory willing to let you verify details usually quotes honestly.
