Sourcing fasteners out of India?The bolt is the easy part.
Finding a mill that holds the grade, meets the shipment date and hands over documents that clear customs — that is the work. Chakraborty Overseas is a merchant exporter in Kolkata. We source from verified Indian manufacturing partners, check the goods against your specification, and ship them properly packed and papered.

What we ship
Every line is sourced from an Indian manufacturing partner we have vetted, then checked against the grade and standard on your purchase order before it is packed.
Where we sit
We are not a mill. That is the point.
A factory sells you what it makes. A merchant exporter finds the factory that already makes exactly what you specified — at the grade, in the finish, in the quantity, on the date. Our work sits between your purchase order and the factory gate.
- Verified partnersUnits we have visited and bought from before, holding ISO 9001 and issuing mill test certificates.
- One point of contactOne order, one invoice, one packing list — even when three factories are involved.
- Documents that clearPrepared to match your bank's requirement, not ours.

How an order runs
We are a merchant exporter, so our work sits between your purchase order and the factory gate. This is the sequence every order follows.
- Step 01
Specification
You send size, grade, standard, finish and quantity. We come back with anything that needs pinning down before we go to a mill.
- Step 02
Sourcing
We place the enquiry with manufacturing partners who already make that item at that grade, and quote with lead time and packing.
- Step 03
Inspection
Goods are checked before dispatch — dimensions, grade markings, plating and count. Third-party inspection on request.
- Step 04
Export packing
Packed for sea freight: moisture protection, marked cartons, palletised and strapped for the container.
- Step 05
Documents
Invoice, packing list, certificate of origin, mill test certificates and shipping documents, matched to your bank's requirement.
- Step 06
Freight & delivery
Booked with our freight forwarding partners — sea or air — cleared through customs at the port of loading and delivered to your destination.
Export packaging
Packed for the sea, not the shelf
Fasteners travel for weeks in a steel box that sweats. Packing is where a good consignment is quietly lost, so we treat it as part of the specification rather than an afterthought.
- Oiled or VCI-protected goods in moisture-resistant liners against condensation
- Export-grade cartons, then palletised, strapped and stretch-wrapped
- Wooden cases with ISPM-15 heat treatment where the destination requires it
- Cartons marked with item, size, grade, batch, net and gross weight
- Packing list matched carton by carton to the invoice
- Bulk and small-pack options — loose kegs, boxes or retail bags to your count

Size, grade, standard, finish and quantity is enough to start. If something is missing we will ask rather than assume.
