§1What this business is
Bark containing oxalates is bought from the forest department or the local panchayat and stored. It is chipped, sieved and fed by screw conveyor into a reactor with hot caustic soda solution (warmed to about 60 °C); steam keeps the temperature steady. The acid is then recovered, crystallised and dried. Oxalic acid is used for cleaning and bleaching, in leather, textiles and metal polishing; the profile says demand is good at home and abroad.
Capacity: 130 tonnes of oxalic acid crystals a year at ₹20,000 a tonne (₹26.00 lakh) at full capacity.
§2Is it right for you?
Who it is for
A chemistry graduate or chemical trader in a forest district with assured bark supply.
Who it is not for
Anyone without chemical-safety training.
Advantages
- Uses a forest by-product (bark)
- Industrial chemical with steady buyers
- Good net surplus in the profile (₹5,85,000)
- Export demand, as the profile notes
Drawbacks
- Chemical process with caustic soda and steam — needs trained staff
- Bark supply depends on forest-department permission
- Large-scale synthetic plants and imports set the price
- Effluent and pollution-control costs
Skills you need
- Chemical process control
- Boiler and reactor operation
- Lab testing of purity
- Effluent handling
Why difficulty 4/5: A real chemical plant: permits, safety, effluent and bark supply all need managing.
§3Market
Who buys
- Leather tanneries
- Textile and bleaching units
- Metal polishing and cleaning-product makers
- Chemical traders
How it sells
- Chemical dealers and distributors
- Direct supply to industrial users
- Export through merchant exporters
Good to know
- The profile says there is good demand in both domestic and international markets.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: Basic Chemicals, Cosmetics & Dyes Export Promotion Council (CHEMEXCIL)
- HS codes are from the WCO HS 2022 list; confirm the 8-digit ITC(HS) line with DGFT or your customs broker.
- You need an Import Export Code (IEC) from DGFT before the first shipment.
§9Risks — where people fail
- Chemical burns and toxic exposure (oxalic acid is poisonous)
- Bark supply cut
- Pollution-control action
- Price pressure from imports
§1030 / 60 / 90-day plan
