§1What this business is
The alloy is melted, poured into moulds with a central hole that is filled with rosin flux, then rolled from bar to rod to fine wire, coiled and packed. Grades run from 60/40 to 5/95 tin/lead; more lead means a lower price. Electrical, electronics and telephone industries buy it. The report makes 100 kg a day and sells at ₹400 a kg; quality to IS 1921.
Capacity: 100 kg a day, 30 MT a year; 60% in year 1.
§2Is it right for you?
Who it is for
Someone from the metals or electronics trade who can manage metal prices and buyers.
Who it is not for
Someone not ready to control lead exposure and fumes.
Advantages
- Very low machinery cost (₹1.78 L)
- Steady demand from electrical and electronics work
- The report sees export potential to the Middle East
- Several grades from one set of machines
Drawbacks
- Tin is imported and its price moves a lot
- Lead fumes are a health and pollution risk
- Electronics is moving to lead-free solder
- Large working capital locked in metal stock
Skills you need
- Alloy melting and composition control
- Rolling and wire drawing
- Testing to IS 1921
- Metal buying and hedging prices
Why difficulty 3/5: Simple machines, but metal-price risk and lead safety need care.

§7Money
How the investment is worked out: Samadhan report: plant & machinery ₹1.78 L, furniture ₹0.50 L, pre-operative ₹0.30 L, working capital ₹11.72 L = ₹14.30 L (term loan ₹2.32 L, working capital ₹10.54 L, own money ₹1.43 L). Building (3,000 sq ft) rented — rent ₹3.60 L a year in the profit statement.
Working capital: Working capital ₹11.72 L (bank ₹10.54 L) — most of the project, because tin is costly; 30 days of raw material and 15 days of finished stock.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: EEPC India
- Get an Import Export Code (IEC) from DGFT before exporting.
- Many markets restrict lead in electronics (RoHS-type rules); check before quoting.
§9Risks — where people fail
- Tin price spikes
- Lead exposure and pollution action
- Shift to lead-free solder
- Composition errors leading to rejection
