§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

2917.11Oxalic acid, its salts and esters

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

A general plan that applies to any business. A plan for this business will be added after research.

  1. Days 1–30: Visit a working oxalic acid from tree bark unit, ask 10 buyers about price and quantity, and get quotations from 3 suppliers.
  2. Days 31–60: Udyam and the licences you need (Udyam registration, GST registration), a project report (DPR), and the scheme or loan file.
  3. Days 61–90: Space and machines, trial production, and first deliveries to 10 customers.
