From a Sourcing Yard to a Leading Custom Fabricator
Founded in 2011 by Syed Hasnain, a veteran in marine engineering and container logistics, Overseas Trading Corporation started as a used shipping container sourcing yard in Kolkata. Sourcing high-quality pre-owned ISO containers for local storage needs quickly laid the foundation for our next major milestone: customized container modifications.
Understanding the growing demand for rapid, relocatable site offices and modular spaces, we established our dedicated fabrication yard in Kolkata. Today, we stand as one of eastern India's primary designers and builders of premium portable office cabins, security booths, toilet units, and bespoke container homes.
We serve a diverse portfolio of over 500 active clients across West Bengal, Odisha, Bihar, and Jharkhand — ranging from infrastructure developers and construction companies to retail startups and resort owners.
