You find genuine mills by verifying them, not by searching harder. Online directories, trade fairs and export promotion bodies will give you names, but the same lists are full of traders, agents and brokers who describe themselves as manufacturers, so the real work is confirming that the unit you are talking to owns the machines and the process it claims. The first half of the checks below can be done from your desk and the second half on the factory floor.
Start with the right cluster
Choose the city by product before you choose a mill. Cotton, denim, home textiles and technical fabrics point you to Ahmedabad and its industrial belt. Polyester, viscose, printed fabrics and sarees point you to Surat, and PP woven sacks and craft textiles point you to Kutch. A supplier who offers all of these from one office is almost certainly a trader.
Within the cluster, work out which stage you actually need. A spinning mill, a weaving unit, a process house and a composite mill are different businesses with different owners, and a genuine weaver will openly tell you that dyeing happens elsewhere.
Desk checks before you travel
- Ask for the GST registration and the Importer Exporter Code, and check that the registered address is an industrial address rather than an office or a market stall.
- Ask for the factory licence or the pollution control consent. A process house that dyes or prints must hold one, and a trader cannot produce it.
- Ask which machines they run, with make, number and width, and compare the answer with the capacity they quote.
- Ask for the names of their yarn or greige suppliers. A genuine mill answers quickly, while a trader is evasive.
- Request a video call from the shop floor during a working shift, with the camera on the machine nameplates.
- Check certifications such as OEKO-TEX, GOTS or ISO directly with the issuing body's public database, using the certificate number rather than the PDF.
What to check on the visit
Walk the whole process, from raw material store to finished goods, and look for continuity. Yarn in the godown should match what is on the looms, fabric on the looms should match what is in the inspection room, and the packing marks should match the orders they say they are running. Gaps in that chain usually mean part of the work is subcontracted.
Count machines and compare against the quoted capacity. A unit that claims a large monthly output but has a handful of looms is booking capacity elsewhere. Look at the inspection tables, the greige stock and the lab, and ask to see recent test reports they issued for other buyers with the names removed.
Take samples yourself from running production, seal them, and send them to an NABL-accredited lab for composition, GSM, shrinkage and colour fastness. A sample handed to you in the office proves nothing about what the mill can repeat.
How we do this for buyers
We make these visits on the buyer's behalf, because most of the checks only work in person and in Gujarati. We audit the unit, photograph nameplates and licences, send sealed samples to an NABL-accredited lab, and then supervise loading when the order ships, with weekly updates in between. Buyers end up with one approved mill plus one backup. If you already have a shortlist, a free 20-minute sourcing review is a quick way to find out which names on it are real.
