How to find a US manufacturer for your product
Start from what the product is made of and how it is made, find the industry code for that process, then shortlist factories in the states where that code clusters.
1. Name the process, not just the product
A phone case can be injection-molded plastic, machined aluminum or sewn leather. Each process belongs to a different part of the industry. Write down the main material and the main process first; that tells you which kind of factory to look for.
2. Find the industry code
US factories report a NAICS industry code to federal programs. Plastic parts are mostly NAICS 3261, machined parts 332710, printed circuit boards 334412 and 334418. Our product directories group the codes for 62 common products so you don't need to look them up.
3. Shortlist by state
Each product directory shows how many facilities report that code in each state and which cities they cluster in. A cluster means more suppliers, more tooling shops and more people who know the process, which usually means faster quotes.
4. Check the factory's records
For larger facilities, the factory page shows EPA program records: whether it reports to the Toxics Release Inventory, its air and water permits, and its inspection history. These are compliance records, not quality ratings, but they confirm the site exists and is active.
5. Ask for quotes
Send the same short brief to several shops: the part or product, material, quantity per order and per year, target date and delivery ZIP code. Every product page here has a quote form; requests go to manufacturers that have claimed their listing.
