To find a manufacturer in China, start with a written product brief, search by the industrial cluster that specializes in your category rather than by keyword alone, and then prove that each candidate is a real factory before you pay anything. Most bad supplier relationships do not fail at production. They fail at the first step, when a buyer picks whoever replied fastest on a marketplace and never checked who actually owns the machines.
This guide walks through the process the way a US Amazon seller, DTC brand or wholesale importer would actually run it, from brief to signed purchase order.
Step 1: Write the brief before you search
Factories quote what you ask for. If you send "a silicone kitchen spatula, how much?", you will get ten prices for ten different products. Before contacting anyone, write a one or two page brief that covers:
- Materials and grade, for example food-grade platinum-cured silicone versus a cheaper peroxide-cured grade.
- Dimensions and tolerances, with a drawing or a reference product if you have one.
- Packaging, including retail box, polybag, carton size and any Amazon FBA labeling you need applied at the factory.
- US compliance requirements: FDA food-contact rules for kitchenware, CPSIA and ASTM F963 for children's products, FCC for electronics that emit radio frequency, California Prop 65 if you sell into California.
- Target unit cost, first order quantity and annual volume. Factories prioritize buyers who can describe a realistic run rate.
A brief does two jobs. It makes quotes comparable, and it filters out suppliers who cannot answer basic questions about your product.
Step 2: Search by cluster, not just by keyword
Chinese manufacturing is heavily regional. Whole towns specialize in one product family, and the strongest factories for your category are usually concentrated in a few places. Some well-known examples:
- Shenzhen and Dongguan for consumer electronics, accessories and electronic components.
- Guangzhou for apparel, leather goods, beauty and personal care, and packaging.
- Yiwu for small commodities, seasonal goods and low-MOQ general merchandise.
- Shantou (Chenghai district) for toys.
- Yangjiang for knives and kitchen tools, and Chaozhou for ceramics.
- Xiamen and the wider Fujian coast for footwear, sportswear and outdoor goods.
Knowing the cluster lets you ask better questions. A spatula supplier based in an inland city with no kitchenware industry nearby is more likely to be a trading company than a moulder.
Step 3: Use the right channels for the job
There is no single best place to search. Each channel has a different strength:
- B2B marketplaces such as Alibaba.com, Made-in-China.com and Global Sources are the fastest way to build a long list. They are also where trading companies are most common, so treat every listing as unverified.
- 1688.com, Alibaba's domestic platform, often shows the price Chinese wholesalers pay. It is in Chinese, most sellers do not export directly, and payment needs a Chinese account, but it is a useful price benchmark.
- Trade fairs, above all the Canton Fair in Guangzhou, which runs in spring and fall. You meet many suppliers in a few days and can handle samples in person.
- Referrals and existing networks, including other sellers, freight forwarders and sourcing agents who already work with factories in your category.
Aim for a long list of 10 to 15 candidates, then cut hard.
Step 4: Separate factories from trading companies
Trading companies are not automatically bad. For low-volume orders or mixed containers they can be the right choice. The problem is not knowing which one you are dealing with, because a hidden middleman adds margin, slows communication and can switch the producing factory without telling you.
Checks you can run yourself:
- Business license. Ask for it. Every Chinese company has an 18-character Unified Social Credit Code. Look the company up on China's National Enterprise Credit Information Publicity System and compare the registered name, address, legal representative and business scope with what the supplier told you. A manufacturer's scope normally includes production, not only "sales" or "import and export".
- Address. Does the registered address sit in an industrial zone or in an office tower? Satellite imagery is free.
- Product range. A factory makes a narrow family of products well. A catalog that jumps from silicone spatulas to LED strips to yoga mats is a trading catalog.
- Live video call. Ask for a walk-through of the production line making something similar to your product, not a showroom tour.
- Certificates. Check that ISO 9001, BSCI or product test reports are issued in the supplier's own name and are still valid. Test reports from an accredited lab such as SGS, Intertek or TÜV can be verified with the lab.
Desk checks will not catch everything. An on-site visit is the only way to confirm that equipment, workforce and capacity match the claim. Our supplier verification service combines the records check, a desk audit and a physical site visit with photo and video evidence, and it works on suppliers you found yourself.
Step 5: Compare quotes like for like
Quotes from Chinese suppliers come back in different formats, currencies and Incoterms. One will be EXW with tooling separate, another FOB Shenzhen with tooling amortized into the unit price, a third will skip packaging entirely. Before you compare, put every quote into one table with:
- Unit price at your first order quantity and at your expected reorder quantity
- Tooling or mould cost, and who owns the tooling once it is paid for
- MOQ and whether it is per SKU, per color or per order
- Production lead time and sample lead time
- Incoterm and port (EXW, FOB Ningbo, FOB Shenzhen and so on)
- Payment terms, typically a deposit with the balance due before shipment
Then calculate landed cost into the US, including freight, customs duty under the correct HTS code, any Section 301 tariff that applies to Chinese-origin goods, the Merchandise Processing Fee, and inland delivery to your warehouse or Amazon FBA. Tariff rates on Chinese goods have changed repeatedly, so check the current rate for your HTS code at the time you order rather than relying on last year's number. The cheapest unit price is often not the cheapest landed cost.
Step 6: Sample before you commit
Narrow the list to two or three suppliers and order samples from each. Pay for them. Free samples tend to come from stock, not from the line that will make your order. Once you choose, ask for a golden sample: a signed-off reference unit that both sides keep and that later inspections are measured against.
Check the sample against your brief, not against your memory of the listing photos. Measure it, test it, and if it needs US lab testing for CPSIA or FCC, start that now rather than after production.
Step 7: Put the terms in writing
Before the deposit leaves your account, agree in writing on price, MOQ, lead time, payment schedule, tooling ownership, defect liability and what happens if goods fail inspection. Book a pre-shipment inspection against an agreed AQL level before the balance payment is released. That timing matters: once the balance is paid, the factory has much less reason to fix problems.
When to get help
You can run every step above yourself, and many US sellers do for their first product. The cost is time, and the risk is concentrated in Steps 4 and 6, where you are relying on what a supplier tells you from the other side of the world. If you would rather start with a vetted shortlist, our product sourcing team turns your spec or reference photo into a brief, matches it against factories by capability, and returns three vetted factories with a normalized quote comparison. The initial search and quote comparison are free, and you can see the full timeline on our order process page.
Still deciding whether to run this yourself or hand it over? Our comparison of using a China sourcing agent versus doing it yourself sets out where each approach makes sense.
If you have a product in mind, send us the spec or a photo and we will tell you where it is made and what it should cost.
