Five industries in West Bengal give the state its manufacturing weight: steel and engineering around Durgapur, Burnpur and Howrah; petrochemicals and chemicals at Haldia; jute and textiles in the Hooghly belt and Howrah; food processing built on the state's rice and vegetable output; and leather at Bantala in Kolkata. No official top-five list exists, so this one is our selection, made where big anchor plants, export strength and working clusters overlap.
For a first-time entrepreneur, the ranking matters less than the entry point. The anchors are large corporate or public-sector plants. The openings for a new unit sit around them: fabrication and castings beside the steel mills, plastic converting near Haldia, finished jute goods, packed foods, and leather goods or footwear. Choose the sector first, the belt second, and only then the incentive, because the state is rewriting its incentive rules this year.
Which are the main industries in West Bengal, and where do they sit?
The table pairs each industry with its belt, what is on record about its anchors, and the kind of unit a newcomer can realistically start.
| Industry | Main belt | On record | Entry point for a new unit |
|---|---|---|---|
| Steel and engineering | Durgapur, Burnpur-Asansol, Howrah | Steel Authority of India (SAIL) plants at Durgapur (2.2 million tonnes a year) and Burnpur (2.5 million); engineering goods are a leading export group, says the India Brand Equity Foundation (IBEF) | Fabrication, castings, machined parts |
| Petrochemicals and chemicals | Haldia, Purba Medinipur | Indian Oil refinery with 8.5 million tonnes a year of capacity | Plastic converting, chemical blending, packaging |
| Jute and textiles | Hooghly belt, Howrah | Most of India's composite jute mills; a hosiery park at Howrah | Finished jute goods, hosiery, knitwear |
| Food processing | Sankrail (Howrah), rice and vegetable districts | First in India for rice and vegetables | Rice and flour products, packed foods, cold chain |
| Leather | Bantala, Kolkata | Close to 400 tanneries in one complex | Footwear, leather goods, finishing |
What does each of the five industries offer a new unit?
Steel and engineering: the parts and maintenance route
Capacity is growing: SAIL's board has approved a 0.89 million tonne expansion at Durgapur (Rajya Sabha reply, 27 March 2026), and Jindal India commissioned a ₹1,500 crore downstream steel facility in October 2025. Big mills buy spares and fabrication from nearby shops, so a small unit that holds tolerances and delivers on time has a steadier first customer than the open market. Our steel and metal manufacturing ideas list unit-level options.
Petrochemicals and chemicals: building next to a port
Haldia sits near the mouth of the Hooghly and has a dock complex. The West Bengal Industrial Development Corporation (WBIDC) runs a 334-acre park there beside units such as Tata Chemicals and Mitsubishi Chemicals. The practical opening is downstream: buy polymer granules and make pipes, films or moulded goods, or blend chemicals for local buyers. The chemical business ideas page sorts options by investment.
Jute and textiles: finished goods over mill capacity
A Lok Sabha standing committee report of August 2025 records 82 of India's 111 composite jute mills in West Bengal. These mills are mature and capital-heavy, so a newcomer is better placed making bags, mats and décor than spinning yarn. For knitwear, the West Bengal Hosiery Association is developing a 125-acre park at Howrah with 2,00,000 sq ft standard factories for small and medium units. See textile manufacturing ideas.
Food processing: rice, vegetables and a full food park
IBEF reports West Bengal first in India for rice, at 171.36 lakh tonnes in 2025-26, and for vegetables. WBIDC's Sudha Ras Food Park at Sankrail, 28 km from Kolkata, covers 49.98 acres, but all 19 serviced plots show as allotted, so ask about later phases or rented space first. Food processing business ideas covers product choices.
Leather: footwear and goods rather than tanning
India's leather and footwear exports were US$4.75 billion in 2025-26, down 1.63% on the year, says the Council for Leather Exports, which lists Kolkata among the main production centres. At Bantala, close to 400 tanneries were running in 2019 when the state added 70 acres to the 202-acre complex for 187 more (Business Standard). Tanning is the pollution-sensitive step; footwear, bags and finishing units face lighter approvals, so most newcomers should start there.
Has West Bengal's factory share really slipped since 2011?
The secondary sector, which covers construction and power as well as factories, fell from 25.13% of the state's gross value added in 2011-12 to 21.80% in 2025-26 (IBEF, April 2026 infographic). Recent numbers look better: industrial output grew 7.3% in 2024-25 against 6.2% nationally, and merchandise exports reached US$12.88 billion in FY26, up from US$9.49 billion in FY20.
The incentive side is in transition. A Press Trust of India (PTI) report of 7 August 2026 says the earlier incentive scheme was discontinued, ₹5,000 crore is set aside in the 2026-27 budget to revive support, and new payouts are to be linked to jobs created rather than money invested.
Which incentives can a new unit count on in 2026?
A manufacturing scheme for micro, small and medium enterprises (MSMEs), WBIS 2026, was reported approved on 20 July 2026. It covers Udyam-registered units that start commercial production on or after 1 October 2026 and runs to 30 September 2031. Zones are set by location, so confirm which one your site falls in.
| Support, for five years | Zone A | Zones B and C |
|---|---|---|
| Interest subsidy on term loans (micro and small units) | 25% of annual interest | 35% of annual interest |
| Electricity duty waiver | 50% | 75% |
Women-owned and SC or ST-owned micro and small units get a full duty waiver capped at ₹10 lakh a year, and certification costs (ISI, BIS, ISO, HACCP) are reimbursed at 50%, up to ₹5 lakh for micro and small units and ₹10 lakh for medium ones. A wider industrial policy is still pending: reports from 3 October 2026 say a group of ministers approved the draft and Cabinet approval is awaited. Central support is separate; see the central MSME schemes.
Where can a new factory find land: WBIDC parks or rented sheds?
WBIDC lists parks at Haldia, Haringhata, Kharagpur, Panagarh, Barjora, Garbeta, Purulia, Durgapur and Asansol-Burnpur. Its listing page does not tag a sector against each park, so ask which industries are permitted before you shortlist. Applications go online through the Silpasathi portal. The Haldia park is advertised with industrial sheds on rent for 10 years, a sensible route for a first unit that would rather not buy land.
What can go wrong with a West Bengal manufacturing plan?
- Start date: WBIS 2026 excludes units that began production on or before 30 September 2026, so commissioning dates can decide eligibility.
- Pollution consent: Chemicals and tanning take longest here. Apply early and cost the treatment plant into the project.
- One-customer risk: A parts supplier tied to a single mill inherits that mill's order cycle. Aim for at least two buyers.
What should you do before committing to a West Bengal site?
- Pick one sector and one unit type from the table above.
- Visit the belt, whether Haldia, Durgapur, Howrah, Sankrail or Bantala, and talk to two running units about buyers and input supply.
- Confirm your site's incentive zone and production start date against WBIS 2026, and register on Udyam.
- Prepare a bank-ready project report with machinery quotes, power load and pollution consent requirements before approaching a lender.

Frequently asked questions about industries in West Bengal
What are the top 5 industries in West Bengal?
No official ranking exists, but five stand out: steel and engineering, petrochemicals and chemicals, jute and textiles, food processing, and leather. They are chosen where anchor plants, export strength and clusters coincide.
Which are the top manufacturing companies in West Bengal?
WBIDC's list of major players includes ITC, SAIL, Usha Martin, Emami, Berger Paints, Birla Corporation, Century Plyboards and Hindustan Unilever. The list is unranked and also carries IT firms, so treat it as a directory, not a league table.
What is the biggest factory in West Bengal?
No official size ranking exists, and plants measured in different units cannot be compared. By capacity, Indian Oil's Haldia refinery (8.5 million tonnes a year, per a 2023 report), the IISCO steel plant (2.5 million) and Durgapur Steel Plant (2.2 million) are the largest named in the sources reviewed here.
How many manufacturing industries are there in West Bengal?
No single official count answers this, because it depends on the definition. The Annual Survey of Industries counts registered factories, Udyam registers micro, small and medium units, and district industrial profiles list sectors area by area.
Can a new entrepreneur get land in a WBIDC industrial park?
Applications are made online through the Silpasathi portal, but availability varies by park. Sudha Ras Food Park shows all plots allotted, while Haldia advertises industrial sheds on rent for 10 years.
