The other comes back a day later, in short Chinese messages, and is noticeably lower. The second is usually the one closer to the machines. When a client asks me how to get the lowest price out of China, I start with a rule I've come to rely on. I call it Brian's Law: > **"If the factory can deal with you in English, you can find a lower price."** It's a rule of thumb, not a physical law. There are exceptions, and I'll get to them. But in my experience it holds often enough that I check it on almost every project. ## Why the Law works Think about what it takes for a factory to talk to a foreign buyer comfortably. Someone has to speak fluent English, answer email in your time zone, send polished quotes, and often travel to trade shows. That is a sales team, and a sales team is overhead. Somebody pays for it, and it's the buyer, built into the price. Often the English-speaking company isn't the maker at all. It's a trading company, or a factory that has grown a trading arm, sitting between you and the people running the machines. Each layer can add its own margin. I've seen jobs pass through more than one before they reach the shop floor. None of that is dishonest. Those companies do real work: they simplify communication and take on some risk. But if your goal is the lowest cost, you are paying for convenience, and the real maker is often one or two tiers further down, in a smaller factory that doesn't have an English-speaking front office. ## Big factories quietly outsource Even when you've found a real factory with real machines, your order may not be made there. Larger factories often subcontract work to smaller shops. They do it when they are at capacity, when a process isn't their strength (plating, certain machining, tooling, finishing), or when a smaller shop can simply do the job cheaper. Signs that it may be happening: - **The quote is fast for a process the line doesn't show.** If they can't show you the machine that makes your part, someone else probably does. - **Different parts, different lead times that don't fit one building.** A part arriving from outside for plating or secondary operations is normal. Your whole part arriving from outside is a different matter. - **Vague answers about who does what.** Good factories are usually proud of their process and happy to explain it. - **Unmarked or oddly packed parts at the dock**, or parts that show up with a different finish or tool marks than the sample. - **A refusal to let you see the process step by step.** Not always a red flag, but worth asking about. This is why the first rule of my factory vetting is to see the line that makes your kind of product. If the big factory is subcontracting, you want to know, and often you'll want to go meet the subcontractor. ![A small Chinese electronics workshop with benches, tools and blue parts bins.](/work/article-workbench.jpg "A small workshop: modest premises, direct access to the person who sets the price.") ## Small factories: the upside and the risk The smaller shops one or two tiers down often have only a handful of clients, and they depend heavily on them. That cuts both ways. **The upside** - **Price.** Less overhead, no sales team, often lower margins accepted to keep the machines busy. - **Attention.** A new client can matter a lot to a small shop. The owner may answer the phone. - **Flexibility.** Fewer layers means faster decisions: a change to a drawing or a small batch can happen without a committee. **The risk** - **Financial fragility.** A small factory with thin cash reserves may struggle if a customer pays late or a material price jumps. - **A client loss can sink them.** If one large client is most of the business and leaves, the whole shop is in trouble, and so is your order. - **Capacity gets squeezed.** When the big client calls with a rush, your job can be bumped. You're the small customer now, and the shop's loyalty goes to whoever pays the bills. Neither side is automatically better. A dependent small factory can be an excellent partner or a ticking clock, and you only find out by looking closely. ![Interior of a small assembly and test workshop with green floor, benches and a laser cutter.](/work/article-lab.jpg) ## How to find and vet them This is the recipe I actually follow. It is harder than it sounds, which is why most buyers stop at the English-speaking layer, but every step is doable. **1. Search in Chinese, on Chinese platforms.** On 1688, the domestic wholesale and sourcing platform, search the product by its Chinese name plus the process, not the English listing title. Useful patterns are the product name with 厂家 (factory), 源头工厂 (source factory) or 定制 (custom made), and the process words such as 注塑 (injection molding), 冲压 (stamping), 数控加工 (CNC machining) or 压铸 (die casting). Read the shop page: a real maker shows machines, workshop photos and a business licence, and describes processes. A trader shows a catalogue of unrelated categories. **2. Tell the factory from the front.** Ask for the 营业执照 (business licence) and read the registered business scope: 生产 (production) points to a maker, 贸易 or 销售 (trade, sales) to a trading company. Treat it as a clue, not proof, since some traders list production and many real factories also list sales. Then test it. Ask who owns the tooling and which machines make your part. A maker answers in specifics. A trading company answers in generalities. Also check that the address on the licence is a place that has a workshop. **3. Go to the cluster.** Most product types concentrate in a few towns, with moulds, plating, packaging and materials within a short drive. Search by town and process, then visit the cluster rather than ordering from far away. Suppliers there also know their neighbours, which is how you find the shop one tier down. **4. Send a clear package.** Drawings, material, finish, tolerances, target quantity and the date you need parts. Ask for a quote broken down by material, processing, tooling and packing, so you can compare like with like. **5. Ask the questions that expose the truth.** Which processes are done in-house, and which does the factory outsource? Which machine will run my part? How many clients do you have, and how much does your largest one matter? What happens to my tooling if we stop working together? Can I see the line running? **6. Visit in person.** I won't recommend a shop I haven't walked. Look at the machines and their condition, the QC station, the stock of material, whether the workers are busy, and what other clients' parts are on the floor. Trust the floor over the brochure. Agree a reference sample before any production run, keep it, and compare the first production parts against it. A good sample proves they can make one part; it does not prove the thousandth will match. **7. Start small, pay carefully.** Run a trial order. Chinese suppliers expect a deposit before production, and setting up a way to pay safely from outside China is its own project. Pay only into a company bank account whose name matches the supplier on the contract and the invoice. A request to pay a personal account, or a different company, is a reason to stop. Pay the tooling and the deposit only against what you have verified, and keep balances tied to inspection. **8. Settle the invoice question.** Ask whether the quote includes a 增值税发票 (VAT invoice, the fapiao) and which kind. A price with a proper invoice and a price without one are not the same price, so compare quotes on the same basis. An invoice from the same company you are paying also helps confirm who you are really dealing with. A factory that won't issue one at all is a flag. **9. Cross-check the English quote.** Find the same or a similar part on 1688 and compare the price and the process. If the English quote is several times the domestic one, you know how much layer is in it. Have someone on the ground confirm what the listing says. **10. Build the relationship.** The best prices and the best attention come after years of paying on time, giving honest forecasts and showing up. A factory's owner will bend a schedule for a customer they trust. No search term finds that. Be honest about what is hard here. Most of this assumes you can read and speak Chinese, be in the country for visits, and take weeks over something that looks like a quick search. Skip any of it and you are back to guessing. ## When not to chase the lowest price The cheapest quote is not always the lowest cost. I'd think twice when: - **The product is safety-critical or regulated**, and a failure costs far more than the savings. - **The volumes are small.** Savings per unit may not justify the extra travel, vetting, and management time. - **The design isn't stable.** Frequent changes need a responsive partner, and sometimes that is the English-speaking one. - **Your timeline is tight.** Finding and qualifying a new shop takes time. - **You need the factory to be stable.** If you can't tolerate the risk of a fragile supplier, paying for a bigger, steadier one is a fair trade. - **You can't have someone on the ground.** A lower price without oversight can turn into rework and delay. Also remember that unit price is only part of the story. See my piece on what landed cost includes before comparing quotes. ## A short checklist 1. Can the factory deal with you easily in English? If yes, ask who actually makes the part. 2. Ask to see the line that makes your product, running. 3. Ask which processes are done in-house and which are subcontracted. 4. Look for the smaller shop one or two tiers down: 1688, the local cluster, referrals. Cross-check the English quote against what the domestic listing suggests. 5. Visit in person, or send someone who speaks the language. 6. Ask honestly how many clients they have and how much one client matters. 7. Check capacity during your production window. 8. Agree on a reference sample before the run, and check production against it. 9. Check the licence scope, pay only a company account matching the contract and invoice, and ask about the VAT invoice. 10. Decide whether the savings are worth the risk for this product. ## Closing thought Brian's Law isn't a promise of a cheaper price. It's a prompt to keep digging when everything is too easy. Sometimes the easy path is right, but you should choose it knowingly, not because it's the only one you could see. Working on something like this? [Get in touch](/contact/).
