Raw material suppliers chahiye for starting this business? Instagram pe seedha DM karo → — reply milega.


Seedhe sawaal, seedhe jawab

₹80L-₹3.5Cr. Machinery alone ₹25-50L (CNC, lathe, measuring tools). Rent first year ₹25-30L. Quality certification ₹4-6L. Working capital ₹20-30L. Start with one product, one customer.
Haan, mechanical or production engineering background bahut zaroori hai. Ya toh 5+ years shop floor experience ya engineering degree. Supply chain, quality, machinery troubleshooting sikhne mein 6 months time chahega. Agar zero background ho toh hire an experienced production manager (₹40-50K/month), par apni knowledge building zaroori hai.
PMEGP se ₹5-10L subsidy mil sakti hai (general category). MUDRA Yojana se ₹10L working capital at 8-9% interest. Tamil Nadu Udyam Sakti Fund se ₹20-30L machinery finance at 0% interest. MSME Cluster Development se common facility access. Total potential: ₹35-50L help. IEC code, Udyam, ISO certification se tax benefits.
ACMA trade shows aur Chennai Auto Expo se direct buyer meetings. LinkedIn outreach to Tier-1 suppliers (Bosch, Motherson, Caparo, Sundram). Tradeindia, IndiaMART par profile banao premium listing ke saath. Tum bhi Thiruvallur cluster ka part ho, toh existing players se supplier contact list mil sakta hai. First 3-4 months cold outreach, sample making, quality proof dikhane ke baad first PO ayega.
Bilkul. Tesla, Bosch Germany, Valeo France ko India se import karte hain. IEC code, Udyam, ISO9001, TS16949 zaroor chahiye. Export ke liye Thiruvallur ka advantage: Chennai Port 35km, established shipping lines, SEZ exemption paisa bachata hai. First order ₹10-20L FOB value se start karte ho, margin 35-50% export mein milti hai vs 18-28% domestic.
Machinery ka second-hand value 40-50% recover kar sakte ho, 2-3 saal mein. Rent ka agreement 11 months ka rakho flexible exit ke liye. Biggest risk: customer concentration (1 buyer par dependent na raho) aur quality rejection. Initial 12 months mein cost control aur margin 25%+ rakna padta hai, nahi toh cash crunch sure. Exit option: larger supplier ko sale karo ya pivot to job work (subcontracting) jisme margin low hota par stable rehta hai.
