Your China Quote Went Up Between the Sample and the Order. Here's What Actually Happened

You agreed a price. The sample arrived and it was right. You confirmed the order, and the number came back higher.

The instinct is that you are being worked — that the low quote was bait and the real price was always going to arrive later. Sometimes that is exactly what happened. More often the increase is arithmetic, and the arithmetic was always there; nobody showed it to you.

The difference matters, because a buyer who understands the mechanisms can push back accurately — on the specific line that does not hold up, rather than on the total. Suppliers respond very differently to the two. "This is too expensive" invites a shrug. "Your tooling amortisation implies 40,000 units and I am ordering 5,000" invites an answer.

Here are the four mechanisms that actually move a price, what each looks like when it is legitimate, and the one test that covers all of them.

Tooling was never in the sample price

Tooling is the mould, die, or custom plate your product needs before a factory can make it at volume — a one-off cost, separate from the per-unit price. Someone has to pay for it. At sample stage you paid for a sample — often one cavity, sometimes hand-finished, occasionally made on a mould that will not survive a production run. The production tooling is a separate cost, and it appears in one of three places: billed to you upfront, amortised into the unit price over an agreed volume, or absorbed by the factory in exchange for a volume commitment you have not yet made.

Only the first is visible. The other two are why a "cheap sample" becomes an expensive order.

Why factories prefer to bury it: an upfront tooling invoice is a conversation about ownership, and ownership is a conversation many factories would rather not have. Harris Sliwoski, a US law firm that litigates these disputes, describes the pattern plainly: it is increasingly common for manufacturers to bundle mould and tooling costs into the per-unit price, and when those costs are not itemised, ownership is never designated.

What that costs in practice: the firm documents a client who was quoted $8,000 for a mould, declined the upfront charge, and accepted a 25-cent-per-unit surcharge instead. Over nearly two decades that surcharge came to roughly $850,000 — about 106 times the original quote. Nobody defrauded them. They simply never asked what the surcharge was amortising against, and the amortisation never ended.

There is a second, less obvious cost. When tooling is folded into unit price rather than invoiced separately, it becomes part of your declared customs value, and you pay duty on it on every shipment. The same firm’s example: a $500,000 order carrying $15,000 of unsegregated tooling attracts roughly $7,500 to $8,000 in avoidable duty per shipment at current rates. We checked that arithmetic — it implies a duty rate just above 50%, which is consistent with where China-origin rates sit for many categories today.

What this means for you: ask whether tooling is included, what it costs, over how many units it is amortised, and who owns it when amortisation completes. Get it before you pay, while you still have leverage. The answer being "it’s included, don’t worry" is not an answer — it is the $850,000 answer.

If your category needs no custom tooling, this mechanism does not apply to you at all, and a supplier invoking it should be able to say what the tooling is.

You are not on the tier you were quoted

Tier pricing is the practice of quoting a different unit price at each volume band, and the bands are steeper at the bottom than most buyers expect. Fixed costs — machine setup, line changeover, material purchasing lots, QC — are spread across the run. At 500 units those fixed costs dominate the unit price. At 50,000 they nearly vanish.

So the number you were given at sample stage was a price at a volume. If you quoted 10,000 and ordered 3,000, you are on a different tier and the price genuinely is different. That is not a bait and switch; that is the same pricing model applied to a different order.

The tell: a legitimate tier change is arithmetically consistent. If the volume halved and fixed costs are a third of the unit price, you would expect the unit price to rise by something in the range of a third — not to double. An increase that outruns the volume change is not a tier change, whatever it is being called.

What this means for you: ask for the tier table. Most factories have one and few volunteer it, because a buyer who can see the tiers can see where the breakpoints are — and a breakpoint is a negotiating position. It is also the fastest way to find out whether ordering 20% more takes you across a threshold that pays for itself.

This is closely related to why the minimum order quantity exists in the first place, which we covered in what you actually pay under each sourcing model. MOQs are set for factory economics, not for yours.

The material lock expired

Quote validity is the window during which a quoted price still stands. A quote holds a set of assumptions about input costs, and those assumptions have a shelf life. For most physical products, raw materials are the largest single component of factory cost — commonly cited in the range of 40% to 70%, though it varies enough by category that you should treat any single figure with suspicion. When the input moves, the quote moves.

Most China factory quotes are valid for 15 to 30 days. Some categories with volatile inputs run shorter. If you sampled in March, deliberated through spring, and confirmed in July, you are not being re-quoted out of bad faith. You are being re-quoted because the quote expired months ago and everyone was too polite to say so.

The tell: a legitimate material re-quote names the material. "Resin went up" is checkable — resin prices are public, and commodity moves flow into factory input costs on a lag of roughly a month or two. "Costs have gone up" is not checkable, and the vagueness is itself information.

What this means for you: get the expiry date in writing at the point of quoting, not at the point of ordering. Then either order inside it or accept that you are asking for a fresh price. If your timeline is long by nature — because you are working around the Chinese New Year shutdown, for instance — agree the re-quote rules upfront: what proof is required, how much notice you get, and whether it touches only future orders.

The currency moved

This one is nobody’s fault, and in 2026 it has been unusually large.

Currency exposure is the gap between the currency you pay in and the currency your factory spends in. Your price is in dollars. Your factory’s costs — labour, materials, rent, electricity — are in yuan. When the yuan strengthens against the dollar, an unchanged dollar price converts to less yuan, and the factory’s margin compresses without anyone changing anything.

The arithmetic, as of September 2026: USD/CNY started the year around 7.01 and sits near 6.71 today, the yuan’s strongest level since early 2023. A factory holding an unchanged dollar price has therefore lost about 4.2% of its revenue in the currency it actually spends. To hold its yuan revenue flat, it would need to raise the dollar price about 4.4%.

That is worth sitting with, because it reframes a category of price increase that reads as opportunistic. A supplier asking for 4% this year may be asking to stand still.

The tell: direction and magnitude. If the yuan strengthened and your supplier wants more dollars, the direction is right. If they want 15% and the currency moved 4%, currency is not what is happening. And if your quote was denominated in yuan all along, currency movement is your gain or loss, not theirs — they have no claim to make.

What this means for you: check the rate yourself before accepting or rejecting a currency-based increase. It takes ten seconds and it is the most objectively verifiable item on this list.

A caveat on this section specifically: these are September 2026 figures. Currency moves, and if you are reading this a year from now the numbers above are history — the mechanism holds, the percentages do not. Check the current rate, not this paragraph.

The sample was not the product

The mechanism: the least discussed reason, and the most common source of genuine misunderstanding. The sample you approved and the product you ordered are not always the same thing. Material grade, thickness, finish, packaging, accessories, certification — any of these can differ between a sample built to impress and a production run built to a spec.

Sometimes the factory upgraded the sample to win the order. Sometimes your own spec changed in ways that felt minor and were not. Sometimes the sample was made on different equipment entirely.

The tell: a legitimate spec-driven increase can be shown as a delta. The supplier should be able to put the sample spec and the order spec side by side and point at what moved. If the two specs are identical and the price is not, spec is not the reason.

What this means for you: get the approved sample documented as a spec, not as an object. A physical sample sitting on a shelf in Shenzhen is not a specification, and it is not something you can hold anyone to. This is also where knowing whether you are dealing with a real factory matters — an intermediary who does not control the line has far less visibility into what actually changed, and less ability to fix it.

How to tell a legitimate re-quote from being worked

Here is the whole thing in one table.

The rule underneath all five rows: every legitimate reason produces a document. A tier table, a dated quote, a named commodity, an exchange rate, a spec delta. None of these are hard for a factory to produce, because all of them already exist internally.

A supplier who cannot produce one may simply be disorganised — plenty of good factories run on WeChat messages and habit. But a supplier who will not produce one, after you have asked plainly, is telling you something about how the rest of the relationship will go.

Ask for the increase itemised against the original quote, line by line. The itemisation is the test, not the number. A factory that hands it over has just given you something to negotiate against. A factory that refuses has answered a different and more important question.

What a China-side partner changes

If you have been through this cycle a few times, you have probably noticed that the increase usually arrives at the worst possible moment — after you have committed to a launch date, told a customer, or booked freight. That timing is not a coincidence. It is when your leverage is lowest, and it is often the first point at which anyone actually does the arithmetic.

The mechanism is that the questions get asked earlier. Tooling ownership, tier table, quote expiry, spec documentation — none of this is exotic, and none of it requires being in China. What being in China changes is when it happens: at quoting, in Mandarin, with someone who has seen the factory’s other quotes and knows which line is unusual. Asked at that point the questions are routine. Asked after a deposit clears, they are a dispute.

The second thing it changes is comparison. A single quote in isolation is very hard to judge — you cannot tell an aggressive price from a normal one without something to compare it against. Running orders across a set of factories in the same categories means the reference points already exist, which is the same reason we consolidate everything one business runs on into one relationship rather than many.

Where this does not win. If you have one established supplier you have visited and trust, and your product has no custom tooling, most of this is overhead you do not need — the relationship is already doing the work. If your orders are small enough that a few percent either way does not change the economics, the fee will cost more than the errors. And no partner can retroactively fix a tooling arrangement you agreed to three years ago; at that point the honest options are to buy the mould out or design around it.

What we do help with is the part before the deposit, which is the only part where any of this is cheap to fix.

If it is useful, here is who we are and how we work with our factories. Or tell us your product and order size and we will tell you what the quote should look like before you get one.
