Frequently Asked Questions

Who manufactures the mono ethylene glycol (MEG) that SPC supplies in India?

Our MEG is manufactured by Reliance Industries Limited at its Nagothane Mfg. Division (ISI CM/L 7800096721). We are distributors, not manufacturers — we supply against the Reliance batch CoA, tested to IS 5295:2023 methods, and dispatch from our Redhills, Chennai warehouse across South India.

What is the CAS number and HSN code of mono ethylene glycol?

The CAS number of mono ethylene glycol (MEG) is 107-21-1. Its HSN code is 2905 31 00.

What is the full form of MEG? Is it the same as ethylene glycol?

MEG stands for Mono Ethylene Glycol. It is the same chemical commonly called ethylene glycol — the IUPAC name is ethane-1,2-diol (1,2-ethanediol), CAS 107-21-1.

What is mono ethylene glycol used for?

MEG is the primary raw material for PET resin and polyester fibre. It is also used in antifreeze and coolant formulations, heat-transfer fluids, unsaturated polyester resins, and as an industrial humectant.

What grades of mono ethylene glycol are available?

MEG is commonly traded as fibre grade (assay 99.9% min), industrial grade, and antifreeze grade. Our on-file TDS (doc no. SPC-TDS-GLY-002) covers General Grade MEG to IS 5295:2023 — purity 99.50 wt% min per the Reliance batch CoA. Tell us your application and we will match the grade.

Can I buy mono ethylene glycol from a supplier in Chennai?

Yes. We stock MEG at our Redhills, Chennai warehouse and dispatch across South India in drums, IBCs, and bulk tankers. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote; lead time is ex-stock to 3 working days.
