How to negotiate price with a Chinese supplier
Which levers actually move a Chinese supplier's price, in what order to use them, and why asking for a discount with nothing to offer does not work.
The price of a Chinese supplier moves when you change one of four variables —quantity, specification, payment terms or a repeat-order commitment— and not when you ask for it. A discount requested without touching any of the four is a request for the factory to cut its margin in exchange for nothing, and the answer is a no or a silently different product. An illustrative example with round figures: a plastic product that sells at 0.95 USD at 3,000 units needs 1.46 USD at 500 units just to avoid losing money, 54% more.
The principle: four variables, and no others
Price is a function of quantity, specification, payment terms and commitment; the discount is the consequence of having moved one of the four. Faced with a discount request that changes nothing, the supplier has three ways out: say no, say yes by lowering the specification without telling you, or say yes by losing money. The third does not happen twice.
| Variable | What you change | What the factory changes |
|---|---|---|
| Quantity | More units of the same reference, or in the same order | Amortises setup and buys material at a better price |
| Specification | What the product contains and how it is packed | Less material, fewer components, less process |
| Payment terms | A larger deposit or earlier payment | Less need for working capital |
| Commitment | A second order with quantity and date | Plans the line and commits material |
The order matters: specification closed, quantity, what can be simplified, payment and finally commitment. Negotiating in any other order is negotiating on a base that is going to move.
Lever 1: quantity, and why you have to ask about the price tiers
“Can you improve the price?” gets a courtesy answer; “what are your price tiers?” gets a list with numbers. The first question asks for a favour; the second asks for information, and information is what lets you decide.
| What you ask | What you get | What you do not get |
|---|---|---|
| “Can you improve the price for me?” | A 2% to 3% gesture with no justification | The cost structure |
| “What are your price tiers?” | A ladder with quantities and prices | Nothing: it is what you need |
| “What quantity would get me to this price?” | A concrete target | A promise you will have to keep |
A factory’s cost is stepped, and that is why its price list is stepped too: machine setup, the printing plate and the minimum material are paid once and do not depend on volume. The price falls in jumps, and the jumps sit at specific quantities: going from 1,900 to 2,100 units when the tier is at 2,000 is worth more than going from 2,100 to 3,000.
Lever 2: specification, and what disappears when the discount is unconditional
When a supplier grants a discount without you having changed anything, the money comes from somewhere, and that somewhere is almost always the product. Specification is the only line item the factory can move without touching its margin.
| Cut | What changes | Where it is detected |
|---|---|---|
| Less material | Thickness, grammage, gauge | Weight and measurements on receipt |
| An inferior component | Cell, power supply, connector, module | Sealed sample or test |
| Cheaper packaging | Box and inner protection | Damage in transit |
| Less process | Per-unit testing, final inspection | Defects in the batch |
The right question is not “can you lower the price?” but “what would have to come out to reach this price?” The first produces a number; the second produces a list, and a list is decided point by point. There are cuts you want —the packaging you were going to replace anyway, an accessory nobody uses— and cuts you do not, starting with anything that covers a certification.
What makes all of the above verifiable is the sealed sample: with a sample signed by both parties, “the same product, cheaper” is checked by weighing and measuring the batch before the cargo leaves China.
Lever 3: payment terms, the lever almost nobody uses
Paying earlier and leaving a larger deposit has real value for a factory with working-capital constraints, and it is the lever almost no buyer uses. The factory buys the material for your order with its own money or with short credit from its supplier; a larger deposit funds that purchase, and that saving turns into price.
| Term you offer | What it gives the factory | What it costs you |
|---|---|---|
| A deposit of 30% to 50% | Buys the material without financing it | More capital paid in advance |
| A deposit on a fixed date | Plans the month’s purchasing | Nothing, if the date is met |
| Balance against inspection | Nothing: it is your protection | It is the limit you do not concede |
The limit is the same one that protects your money: the deposit can go up, but the balance is not released before inspection. That is the same logic we apply to every order, and it is set out in our quality inspection process.
A discount that arrives by changing the invoice is not a discount: it is another transaction. The general VAT rate on goods in China is 13%, and sellers quote with or without an invoice. Without an invoice there is no export declaration in the seller’s name, so the goods leave covered by another company’s document, a practice the State Taxation Administration of China placed under formal supervision with announcement 2025 no. 17. And the counterparty changes: the document you present to your tax authority no longer corresponds to what you paid. Always ask for the price with an invoice. MeliPrep, the China sourcing agent behind this guide, buys in yuan, pays into the supplier company’s account and withholds the balance against inspection.
Lever 4: commitment, a second order with a date is worth more than a promise
A verbal promise of volume is worth nothing; a second order in writing, with quantity and date, has a value the factory can calculate. Setup is amortised across the relationship and not across a single order: “if this goes well, I’ll buy more” gets you nothing, and “3,000 units in March, in writing” gets you a price that is not the price of a one-off purchase. What makes the commitment credible is the date, not the quantity.
The three things that destroy your position
The three mistakes that cannot be fixed later are made before the first offer.
| Mistake | Why it destroys your position | What to do instead |
|---|---|---|
| Asking for the lowest price before closing the specification | The price is not comparable with anything, and if you add a requirement later it goes up while you have nothing to offer | Close the specification and negotiate on that document |
| Revealing your market’s selling price | The price stops being cost plus margin and becomes the maximum you can pay | Talk about your target purchase price, not your selling price |
| Playing two suppliers against each other badly | Both parties learn that you will leak their quote; if you push both to the floor, both walk away | Use the other quote as a reference, without a name and without a figure to beat |
What is not negotiable: safety
If a specification exists because a certification requires it, the answer to “can it be cheaper?” is no, and the supplier who says yes is telling you something about themselves. Certification is practised on the finished product as tested: changing the material or the component means the certificate no longer covers what you are shipping.
| Country | What governs it | Consequence |
|---|---|---|
| Mexico | The NOM for the category: the certificate is registered with customs before the first shipment, and the importer with an RFC appears on it and on the pedimento | A specification cut puts the clearance at risk, not only the product |
| Brazil | ANATEL homologation is a precondition for import for products on the reference list, and it is not transferable | The holder must be an entity with a CNPJ; without homologation there is no document covering the import |
| Argentina | Electrical Safety Technical Regulation; Resolution 16/2025 accepts safety certificates issued abroad | The regime differs from Mexico’s and Brazil’s, and depends on the category |
In Brazil, Inmetro certification also requires the holder to be legally established in the country in the product families covered by that requirement. It is a structural requirement, not a price one. And in all three cases it is worth stating which certificate the product needs before the quote, because discovering it afterwards turns a saving of cents per unit into a batch stopped at customs.
The conversation script
The negotiation is done in five messages, and the first one does not mention price. It is short enough to follow without improvising, and it fits the order of steps described in how it works.
| Step | What you write | What you get |
|---|---|---|
| 1. Close the specification | “Before we talk about price, let us confirm what it includes: material, measurements, packaging, accessories and certificate.” | The base against which everything is compared |
| 2. Ask for the ladder | “What are your price tiers, and what quantity does each one correspond to?” | The list of jumps and the tier that suits you |
| 3. Ask what can come out | “To reach X USD, tell me what can be simplified and how much each point saves.” | A list that you decide, point by point |
| 4. Put the levers together | “I will go up to N units, leave a 50% deposit and confirm a second order in March in writing. Which tier do we land on?” | The four variables on the table |
| 5. Close in writing | “I confirm: agreed specification, N units, price with invoice, 50% deposit, balance against approved inspection, delivery on [date].” | A document you can hold them to |
The most common mistake is starting at step 4: without the specification closed, the ladder in step 2 means nothing.
The honest part: the best negotiation is the one on the fourth order
The buyer with the most leverage is not the one who negotiates best: it is the one who has already paid on time three times. By the fourth order the factory knows that payment arrives on the date, that the specification does not change halfway through the run and that the order is not cancelled: that reliability gets you the price that is not on the ladder.
Track record also changes what you pay for the service: in MeliPrep’s published pricing tiers —8% up to 5,000 USD a month, 7% between 5,000 and 25,000, 6% between 25,000 and 100,000 and 5% above that— the percentage falls because recurring volume changes the economics of the work. The negotiation that matters is not the one on the first order: it is the one you no longer need by the fourth.
