1. At a Glance
Tanfac Industries is that quiet batchmate you ignored in school, who shows up at the reunion driving a supercar. Once a sleepy joint venture between Aditya Birla and TIDCO, this fluorine chemist has turned into a ₹4,000 crore market-cap juggernaut, compounding profits faster than you can spell “hydrofluoric acid.”
At ₹4,004 per share, it’s up 105% in the past year — and the market’s still drooling. The stock trades at a P/E of 42.5, book value ₹340, ROE 32%, ROCE 42%, and negligible debt (₹31 crore).
Latest quarter? Revenue ₹169 crore, PAT ₹17.2 crore, down 11% QoQ but still sizzling after a 51% YoY sales jump.
In FY25, Tanfac clocked ₹695 crore in revenue and ₹94 crore in PAT, with margins around 20%. All this with just one main plant sitting calmly in Cuddalore, Tamil Nadu — proving you don’t need 12 factories if one can spit gold.
2. Introduction – The Revenge of a Boring Chemical Company
Picture this: It’s 2019. Tanfac is a forgotten smallcap selling acids to fertilizer companies. Cut to 2025 — it’s doubling capacity, signing Japanese contracts, and making fluorine sexy again.
You know a company’s arrived when retail investors start Googling “what does hydrofluoric acid do?”
What started as an inorganic chemicals factory is now a precision fluorine house, with customers spanning aluminum smelters, glass makers, steel rerollers, and specialty chem players. Its partnership with Anupam Rasayan lit the fuse — ARIL bought Birla’s stake in 2022 and turned Tanfac into its captive fluorine arm.
Since then, capex after capex, and suddenly, the company’s EBITDA looks like it’s been on creatine. From ₹72 crore in FY24 to ₹142 crore in FY25, it’s been a chemical transformation worthy of Breaking Bad — minus the crime, plus dividends.
3. Business Model – WTF Do They Even Do?
Tanfac makes fluorine-based chemicals, but saying that undersells how dangerous and critical their products are. Their breadwinner, Hydrofluoric Acid (HF), is an ingredient that can etch glass, clean semiconductors, refine petroleum, and dissolve rust (and, uh, humans — not recommended).
Here’s the fun lineup:
- Core Acids: Hydrofluoric, Sulphuric, and Oleum.
- Derivatives: Aluminum Fluoride, Potassium Fluoride, Potassium Bifluoride.
- Specialties: Boron Trifluoride complexes, Poly Aluminum Chloride, and Peracetic Acid.
- By-products: Calcium Sulphate (Gypsum).
They’re now upgrading from bulk to high-value chemicals like solar-grade difluoride and refrigerant gases — exactly where margins hide.
