LIMESTONE

Abundant in many parts of the world, limestone is a sedimentary rock that comes in different shades, ranging from dark grey to white. A few places around the world lack easy access to limestone. In Chile, for example, limestone is often at high elevation in mountainous regions or is in river deltas, while in Bangladesh, limestone is scarce as most of the earth is clay- or mud-based rather than rock-based.

Shun Shing controls about 25% of Bangladesh’s limestone import market.
