Here's the dirty secret of domestic sourcing: finding US manufacturers is the easy part. Directories like ThomasNet list tens of thousands of them. The hard part — the part nobody warns you about — is getting them to actually quote your job. It's common to email 40 or 50 US factories about a project and hear back from a handful, and get real quotes from fewer still. If you've had that experience and assumed you were doing something wrong, you probably weren't. The system is just built that way.
Understanding why the response rate is so low tells you how to beat it.
They're busy with existing accounts. A US contract manufacturer running near capacity has no incentive to chase a new, small, unproven customer. Quoting your job costs them engineering time they'd rather spend on the accounts already paying them. You are, from their side, speculative work.
You look small and risky. A cold inquiry from an unknown company, for a modest volume, reads as high-effort and low-reward. They can't tell if you're a serious buyer or someone who'll vanish after they spend two hours on a quote.
Your inquiry is hard to quote. Vague RFQs ("can you make this? what's the price?") without a real spec force the manufacturer to either chase you for details or pass. Most pass. An incomplete inquiry is easier to ignore than to answer.
You contacted the wrong shops. Many directory listings are for companies that don't actually do your process at your volume, or are trading/distribution outfits, not manufacturers. A chunk of your non-responses are simply mismatches.
Send a complete, quotable RFQ. This is the highest-leverage fix. A manufacturer can quote a real product spec — material, dimensions, tolerances, quantities, timeline — in minutes. Give them everything they need to say yes without a follow-up email. The easier you make it to quote, the more quotes you get. Attach a drawing or a reference sample if you have one.
Signal that you're a serious, repeat buyer. Manufacturers prioritize customers with a future. State your volume, your reorder cadence, and your timeline concretely: "Initial run of 5,000, expected quarterly reorders, PO ready this month." Specifics change how worthwhile you look, the same way they move a factory's MOQ.
Qualify the shop before you send. Don't blast 50 listings. Spend the time up front to confirm each one actually runs your process at your volume — check their capabilities, their typical customer size, their equipment. Twenty well-matched inquiries beat fifty scattershot ones, and your response rate on matched shops is dramatically higher.
Make the first contact easy to answer. A short, specific first message ("Do you run [process] for runs of [volume]? If so, I have a complete spec ready to send.") gets a yes/no faster than dumping everything in a cold email. Then send the full RFQ to the ones who bite.
Follow up once, professionally. A single polite follow-up a few days later meaningfully lifts response rates — inquiries get buried, not always rejected. One follow-up, not five.
Even doing everything right, domestic quoting is a numbers game with a lot of drop-off: qualified shops → responses → actual quotes → competitive quotes. To end up with three or four comparable US quotes, you often need to start with a couple dozen well-matched, well-briefed inquiries. That's a real time cost, and it's the main reason importers default to overseas sourcing even when domestic might win on total cost — not because China is always cheaper, but because Alibaba compresses the find-and-quote loop into days while the US process takes weeks of chasing.
The entire reason quote-aggregation services exist is this response-rate problem. Instead of you personally emailing 50 shops and chasing quotes for weeks, the service maintains supplier relationships and sends your RFQ to matched, responsive manufacturers — so quotes come back because there's an existing relationship and a professional, complete brief on the other end. That's the core of what JustSpec does: turn "I need this made" into a set of comparable quotes from manufacturers who actually respond, US and China both.
Whether you do it yourself or use a service, the principles are the same: send a complete spec, look like a real buyer, target matched shops, and follow up once. For where this fits in the full process, see the complete guide to product sourcing and how to find US manufacturers.
