Finding manufacturers in China starts by describing the type of factory the product needs. Searching only the product name can produce many sellers; fit with the required material, process, trial volume and destination market determines whether a lead is useful. This guide focuses on discovery and shortlist construction. Use the separate supplier verification guide for evidence after the shortlist exists.
Write a target-factory profile
Describe intended use, non-negotiable construction and materials, critical processes, trial and annual volumes, packing, destination markets, timing and acceptable alternatives. Separate processes that must be performed in-house from those that may be subcontracted if disclosed. Two businesses selling similar metal-housing products may specialize in different operations such as stamping, die casting or final assembly. A similar catalog photograph does not establish process fit.
Build a longlist from different sources
Use product images, industry vocabulary, process terms, exhibition material, public company pages, manufacturing-cluster clues and reliable referrals. For every lead, save the source URL, date, legal company name and evidence of product or process relevance. A storefront or product photograph begins as a seller lead, not a confirmed manufacturer. If an image is the starting point, read the image-to-manufacturer guide first.
Run a low-cost fit screen
Ask each candidate the same short questions: Is there a current comparable model? Where are critical processes performed? Can the requested trial volume be sampled or produced? What development stages would be needed? What evidence can be supplied and when? Defer candidates that cannot meet a hard process, volume or market condition. For ambiguous replies with potential, record a precise follow-up rather than instantly approving or rejecting.
Reduce the longlist to comparable candidates
Give each lead an identifier and classify it as an existing similar item, a modified existing item or a new development. Record product evidence, key process, sample availability, main differences, communication status and next owner. Prefer a few businesses that can respond to the same brief, explain deviations and offer a sample path. A shortlist is useful because its entries can be compared, not because it is long.
Use one RFQ, then verify
Only a reasonably stable product revision makes prices and lead times comparable; the RFQ guide explains the document. Before committing to a purchase, check company identity, samples, critical processes, contracting party and payee. A directory listing, platform badge or factory video cannot independently prove production capability for the target item. The buyer should separately arrange a qualified provider if on-site verification is needed.
Shortlist handoff fields
Candidate ID | legal name | source and date | product or process fit | existing or development route | trial-volume response | main deviation | sample plan | open checks | next owner. Mark unsupported fields pending. This document supports the next inquiry and sample round; it is not a list of audited approved factories.
