Who We Are
IG Petrochemicals Ltd. operates India's largest single-location phthalic anhydride complex -- 270,000 MTPA across five plants at Taloja, Maharashtra -- anchoring the country's coatings, plasticiser, and specialty chemical supply chain.
Our Story
Founded in 1992, IG Petrochemicals has grown into India's largest single-location phthalic anhydride complex with 270,000 MTPA capacity across five plants. What began as a single production line has become the backbone of India's PA supply, built through disciplined expansion over three decades.
The entire complex operates at Taloja, Maharashtra -- inside the Maharashtra chemical corridor, just 50 km from JNPT/Nhava Sheva, India's largest container port. This location gives IGPL direct access to imported feedstock and export channels while staying close to the country's largest concentration of downstream customers.
The business is structured around phthalic anhydride as the core product, with byproduct recovery of maleic anhydride and benzoic acid, and downstream integration into diethyl phthalate. This model maximises value per tonne of feedstock, turning process chemistry into commercial advantage.
Our Role
Phthalic anhydride is one of the most critical chemical intermediates in Indian industry. It enables the production of alkyd resins for paints and coatings, plasticisers for flexible PVC, unsaturated polyester resins for construction, and key agricultural chemical intermediates.
Without PA, there are no alkyd resins, no flexible PVC pipes or cables, no key plasticiser intermediates like DOP and DOTP, and no UPR for fibreglass and construction panels. IGPL's output anchors the domestic supply chain, providing the scale and consistency that downstream manufacturers depend on.
With approximately 50% of India's PA market share, IGPL's operational decisions directly affect product availability across multiple downstream industries. This is not just manufacturing -- it is industrial infrastructure.

Strategic Position
IGPL's manufacturing base is not just a plant — it is industrial infrastructure that anchors a significant portion of India's downstream chemical economy. Understanding why scale matters in this category is central to understanding the business.
Value Chain Role
Phthalic anhydride sits at a critical junction in India's industrial value chain. It is the primary raw material for plasticisers used in PVC, the foundation of alkyd resins used in architectural and industrial coatings, and the basis for unsaturated polyester resins used in construction and automotive composites.
Domestic manufacturing scale matters in this category. PA is a heavy, bulk chemical that does not travel well — freight costs, handling risks, and delivery continuity all favour local production. Indian downstream manufacturers depend on reliable, consistent domestic supply to run their own operations.
IGPL's five-plant complex at Taloja provides this reliability. With approximately 50% of India's domestic capacity operating from a single integrated campus, the company's scale creates meaningful operational and logistical efficiencies that benefit both IGPL and its customers.
Integrated Operations
The catalytic oxidation of ortho-xylene produces phthalic anhydride as the primary product. But the process also generates valuable byproducts — maleic anhydride from the gas phase and benzoic acid from the liquid residue. IGPL recovers both, along with diethyl phthalate produced downstream from PA.
This integration means every tonne of ortho-xylene yields more economic value than PA alone. The byproduct streams carry high incremental margins because their feedstock cost is effectively zero — they are captured from waste streams that would otherwise require treatment.

Purpose
To be the most reliable large-scale chemical manufacturer in India's industrial supply chain -- combining scale, process excellence, and downstream integration to deliver consistent value.
To produce phthalic anhydride and downstream products with the highest standards of process discipline, operational safety, and commercial reliability -- anchoring India's coatings, plasticiser, and specialty chemical industries.
Our Strengths
Five PA plants on a single campus at Taloja. India's largest single-location PA complex -- a scale advantage that took three decades to build and cannot be replicated quickly.
Wacker Chemie Von-Heyden Low Energy Process. PA purity of 99.8% or above. Lowest energy consumption per tonne in its class -- proven technology operating at scale.
PA as the core, maleic anhydride and benzoic acid from byproduct recovery, diethyl phthalate from downstream integration. Multiple value streams from one feedstock cycle.
Location
Maharashtra's major industrial zone with well-established chemical infrastructure, reliable utilities, and strong transport connectivity.
Direct access to India's largest container port for OX imports and PA exports. Proximity to Nhava Sheva reduces logistics costs and transit times for international trade.
Proximity to India's largest concentration of downstream customers and suppliers. Paint, plasticiser, and specialty chemical manufacturers are within trucking distance.
