§ 01

What we do, and how we go about it

Sphere Chem Resources is a trusted supplier and trader of a wide range of industrial and specialty chemicals. We cater to diverse industries across India and to international markets, with a commitment to quality, reliability and customer satisfaction that we would rather demonstrate than advertise.

A trading house earns its place by being useful in the unglamorous parts of the transaction — holding the right grade, quoting honestly, packing correctly, and telling a customer early when something has moved. Our customers reorder because those things hold, consignment after consignment.

Our quality management system is certified to ISO 9001:2015, with the scope recorded as the trading of chemicals. Material is supplied against manufacturer documentation, and we will confirm grade, concentration and packing in writing before despatch.

Five things we hold ourselves to

  1. i

    Quality

    Uncompromised quality in every product we deliver.

  2. ii

    Integrity

    Honest, transparent and ethical business practices.

  3. iii

    Reliability

    Consistent supply and timely delivery.

  4. iv

    Innovation

    Continuously improving to meet evolving industry needs.

  5. v

    Customer focus

    Building long-term relationships through trust and support.

    Grade, concentration, mesh and packing worked to your specification.

Across India, and out of it

We supply quality chemicals across India and to international markets. Kolkata puts us close to the eastern ports and to the mineral belt, which is a practical advantage for anything moving in drums, bags or containers.

Export enquiries are welcome from a single consignment upward. Send the specification, quantity, packing preference and destination port, and we will come back with a landed proposal and the documentation you will need at your end.
