Riddhi Siddhi Impex started in Mumbai as an importer and exporter of stainless steel flat products. Supplying standard mill material brought us up against the same problem again and again. Manufacturers were buying stock coil widths, then paying for extra machining, scrapping the offcut, waiting longer for delivery, and absorbing the cost of all three.
About Riddhi Siddhi Impex
Precision Stainless Steel Strip, Foil & Shim Solutions Since 2002
Riddhi Siddhi Impex has manufactured stainless steel strips, foils and shims from Mumbai, India since 2002. We also supply stainless steel coils, sheets and plates from stock. Our high nickel alloy range covers the same flat product forms, and the material moves to buyers in India as well as overseas markets.
Our manufacturing unit and warehouse together help us hold a monthly supply capacity of 400 to 500 tonnes. Backing that output is an inventory of close to 1,000 tonnes across stainless steel and high nickel alloy products. On the slitting side, our lines take widths from 3 mm upwards. Width tolerance stays inside ±0.1 mm, and that margin is what lets us serve applications where accuracy decides whether a part is usable.
We operate under ISO 9001, ISO 14001 and ISO 45001 certified management systems. Four things have built our long-term customer relationships: manufacturing capability, ready stock, consistent quality, and dependable service that customers can plan their schedules around. Our guiding philosophy sums it up:
Our Journey Since 2002
Our solution was precision slitting and custom manufacturing. Customers could now order strips, foils and shims in the exact width, thickness and temper their application called for. The shift turned a trading company into a specialised manufacturing partner, with customised flat products and tighter consistency as the output.
A team of around 30 people runs the business today. They cover manufacturing, warehouse operations, quality inspection and customer support, and every order passes through all four. One customised width or a full production quantity: the attention given to dimensional accuracy, product quality and delivery commitments doesn't change with order size.

How an order runs
How We Process Every Order
Our sales and technical team handles every enquiry directly, so the material a customer receives matches the application it was ordered for.
Enquiry
Requirements reach us by phone, WhatsApp, email or the website enquiry form.
Technical review
We review grade, thickness, width, temper, finish and quantity, then confirm stock availability with pricing. Some suppliers respond by recommending the nearest available size. We quote against the dimensions actually requested wherever it is possible to do so.
Precision slitting
Confirmed orders move to our precision slitting facility, followed by edge conditioning to the customer's specification.
Inspection
Every batch goes through quality inspection before packing. We verify dimensional accuracy and product quality at that stage.
Documentation & dispatch
We issue Mill Test Certificates and can supply EN 10204 Type 3.1 or Type 3.2 certification on request. Material is packed in export-quality packaging that protects slit edges through transit.
