Imagine a buyer with a shortlist of suppliers found through an online marketplace. A quote comes in lower than the rest, the salesperson responds fast, and the product photos look exactly like what the buyer wants to sell. The deposit is paid. A few weeks later, the buyer discovers the price did not include the mold, the inner packaging, or the truck ride from the factory to the port. Or the company that received the deposit turns out to be a trading office that has never controlled a production line and cannot explain why the batch is delayed.
That example is hypothetical, but the shape of it is common. The supplier did not necessarily lie. The buyer never asked what the price covered, who was receiving the money, or who would answer if the goods came out wrong. Most of the cost of a first order comes from assumptions nobody wrote down. So start by breaking the price open.
1. Start with the price, then break it open
A unit price is a claim, not a fact. It means nothing until you know the quantity it is based on, the costs it includes, the incoterm it assumes, and how long the number is guaranteed to hold.
The first questions are mechanical, but they sort suppliers quickly:
- Does the price include tooling or mold costs? Many products require an initial mold before the first unit is made. Some suppliers quote product and mold separately; some fold the mold into the unit price. Both can be legitimate. The problem is discovering which approach you agreed to after the deposit.
- Does the price include packaging? Inner boxes, poly bags, inserts, cartons, and labels are often quoted separately. A supplier with a higher unit price may simply be the one that remembered the packaging.
- Does the price include inland transport to the export port? A factory farther from the coast may quote less per unit but charge more to truck the goods to port. The total landed cost is what matters.
- What incoterm is the quote based on? EXW puts responsibility on you from the factory door. FOB keeps it with the supplier until the goods are on the ship. CIF and DDP push more onto the supplier, and the price should reflect that.
- How long is the quote valid? Material prices move. A quote that is valid only ‘for now’ is not a quote you can plan against a month later.
A transparent quote may look more expensive line by line, but it lets you compare suppliers on the same basis. A cheap per-unit price with exclusions is often the expensive total price once the mold, the packaging, and the inland freight are added by surprise. The question is not which supplier has the lowest number. The question is which supplier’s number describes the whole job.
2. Verify the entity, not just the website
The company that quotes you is the company you will pay, and the company you will hold responsible if the order fails. So you need its exact legal identity.
Ask for the full name on the business license. Then ask for the name on the bank account you will be asked to wire to. If those two names do not match, the money is going somewhere other than the entity that quoted you. Sometimes this is legitimate, a parent company may collect payments for an export subsidiary, but you need to understand the structure before you pay, not when you try to claim compensation.
Ask whether the supplier is a manufacturer or a trading company. If it is a trading company, ask which factory produces the goods, whether that factory is under contract with the trader, and whether you can speak to the factory directly. A trading company is not automatically a problem. Many traders manage several factories, handle quality control across categories, and communicate more clearly than a factory with little export experience. In some product categories, a good trading company is the more practical partner. The red flag is a trading company that claims to be a factory, because then your questions about production capacity, lead time, and defect responsibility are being answered by someone who does not control those things.
Ask whether they accept a video walkthrough of the production facility or a third-party audit. A supplier that refuses has a reason, and the reason is usually not that they are too busy. The audit does not need to be elaborate. Someone standing on the production floor, showing the machines, the line, and the materials, answers more than a page of claims.
The entity you contract is the entity you can hold accountable. If that entity does not make the goods, your contract is with a coordinator, not a maker, and your remedies shrink accordingly.
3. Put the customs trail on the table
Your shipment will cross a border, and someone has to declare it under a tariff code. The World Customs Organization maintains the international standards that customs authorities use to classify traded goods under the Harmonized System, covering classification, origin, and valuation.
Ask the supplier what HS code they plan to declare for your product, and who determined it. If the answer is ‘our forwarder handles that,’ ask for the forwarder’s name and get the code in writing. If the supplier chose the code themselves, ask whether they have shipped this exact product under that code before.
Ask which export documents you will receive, commercial invoice, packing list, bill of lading, certificate of origin, and ask for the format and when you can expect them. In a first order, these documents are not paperwork. They are the evidence your customs broker, your bank, and your own records will rely on.
If the quote is DDP, the supplier is responsible for delivery and duty, which means they own the import side. Ask who bears the cost if the declared code is wrong and the shipment is held: the extra duty, the storage, the delay. A supplier who says ‘it will be fine’ is not taking responsibility. A supplier who says ‘we will fix it and cover the cost’ has put the risk in the right place.
A wrong declaration can mean delay, extra duty, and customs queries. Even if the supplier eventually resolves it, the delay is your delay. Your stock sits at a port while your customers wait. That is why the HS code is not a technical detail. It is a business term.
4. Make the sample prove the spec
A furniture-sourcing buyer’s guide puts the pre-order checks in plain terms: check the customization scope, check the sample, and check the supplier’s material control process before placing an order. The same logic applies across most product categories.
Start with the sample’s origin. Was it made to your specification, or was it pulled from existing stock? A supplier that already makes a near-identical product can send you that product as a sample and call it custom. It proves they can make something. It does not prove they can make yours. Ask what changed in the sample compared to the supplier’s standard product, and get the changes written down.
Ask what the sample costs, how long it takes, and whether the charge is credited against the first production order. A supplier that charges a fair sample fee and credits it later is behaving like a business. One that ships free samples to everyone is spending that cost somewhere, usually in your price or in the quality of the goods.
Ask who keeps the approved reference sample, often called the golden sample, and how it will be used during production. If the golden sample stays with the supplier, ask for photo and measurement evidence against it during the run. If you keep it, ask whether the factory has its own copy for the production line. A golden sample with no written spec is just an object. A golden sample with a spec that covers materials, dimensions, color, weight, and function is a contract.
Ask what happens if the bulk goods deviate from the approved sample. Rejection, rework, and negotiated discount are all possible outcomes. The right outcome depends on the product and the deviation. What matters is that the supplier answers before production, not after.
And ask who controls material sourcing. If the supplier buys raw materials on the open market for each order, material quality can drift between the sample and the bulk run. Ask how they keep that from happening.
5. Ask who holds the certificates
Certificates are only useful if they cover the right product, the right materials, and the right legal entity. Ask:
- What material specifications and test reports can you provide with the order?
- Which legal entity holds them, the seller, the factory, or a brand that is not involved in this transaction?
- Do the certificates cover the exact factory that makes your goods, or a group company with a different name?
- Do they cover the materials you are buying, or a similar product from the same material family?
The last two questions catch the most disappointing discoveries. A factory group may hold a certification under a parent company name while the subsidiary that makes your product has no coverage. A supplier may present a test report for a product that looks like yours but uses different materials. At customs or in market surveillance, an inspector may ask for a document that names the producing factory and the materials in your shipment. A brochure from a related company does not clear that bar.
If your product contains food substances, this matters even more. In August 2026, the U.S. Food and Drug Administration published a proposal that would require the submission of generally recognized as safe (GRAS) notices. If your product contains substances that are supposed to be GRAS, ask whether the manufacturer or supplier holds the GRAS documentation. A vague answer is a risk to resolve before the order, not after.
6. Fix your rights before you pay the balance
The payment structure of a first order is where the relationship becomes real. Before you send the deposit, agree on what happens at the end.
Ask what the production lead time is and how progress will be reported. A written update every few days, with photos or video at defined milestones, costs the supplier little and gives you early warning. If the supplier says ‘we will send photos when it’s ready,’ you will not know about a problem until it is too late to fix.
Ask whether they accept a third-party pre-shipment inspection. If they do, ask what happens if the goods fail it. The answer you want is a plan: the supplier fixes the defects, the inspector rechecks, and the shipment goes when the goods pass. The answer you do not want is a vague ‘we will discuss it when we get there.’
Ask what deposit is required and when exactly the balance is due. If the balance is due before inspection, the supplier has no financial reason to make the inspection pass. If the balance is due after inspection, the supplier has a strong reason to fix what the inspector finds. In a first order, the inspection milestone is your main leverage. Do not trade it away.
Ask what happens if the shipment is late. Some delays are reasonable, such as raw material delays or port congestion. But ‘late’ needs to have a consequence, a written revised date, a discount, or at minimum a commitment to tell you early. A supplier that treats the lead time as an estimate and the delay as your problem is telling you how future orders will go.
Ask which law applies if there is a dispute, because the answer affects whether you can actually use your contract. You may not want to litigate in a foreign jurisdiction, but you should know what you agreed to.
Finally, fold packaging and labeling into the same conversation. Ask for the carton details, the label layout, and who approves the artwork before production begins. If you approve the artwork after the boxes are printed, you will own the mistake.
Before the deposit, record each supplier’s answers side by side so the differences are visible. A blank row is itself an answer.
| Checkpoint | Supplier A | Supplier B | Supplier C |
|---|---|---|---|
| Unit price and what it includes (materials, tooling, packaging, inland freight) | |||
| MOQ and whether it applies per SKU, color, or size | |||
| Sample policy: cost, quantity, timeline, and whether it is produced to spec | |||
| Material specification and who controls material sourcing | |||
| Certifications and test reports, and which legal entity holds them | |||
| HS code the supplier plans to declare on export documents | |||
| Incoterm quoted and who pays duties | |||
| Payment terms: deposit, balance trigger, refund or credit conditions | |||
| Production lead time and how progress is reported | |||
| Inspection rights: in-process and pre-shipment, including third-party access | |||
| Packaging, labeling, carton details, and artwork approval | |||
| Late delivery and defect remedies |
What a supplier says in conversation is useful. How willing they are to put it in writing is decisive. A supplier who hedges on written answers has already shown you what the relationship will be like after the deposit: you will be chasing them for documents, updates, and corrections, with less leverage than you have now.
The questions cost nothing. The surprises cost the order. And the supplier who will not answer in writing has given you the most useful answer of all: this is the wrong partner for a first order.
If the written answers check out but you still cannot verify them from abroad, the factory floor, the sample, the pre-shipment inspection, that is the part a China sourcing agent covers. SourcingAll handles supplier vetting, factory audits, sample coordination, and pre-shipment inspection on your behalf.
