Non-trade cement" typically refers to cement that is not sold through regular commercial channels or to end-users directly. Instead, it is often used for specific projects or purposes where there might be special requirements or arrangements.

Non-trade cement may include bulk orders directly from manufacturers for large-scale construction projects, government projects, or infrastructure developments. It could also involve cement used for research or testing purposes, such as in laboratories or academic institutions. Additionally, non-trade cement might be used for specialized applications like in the production of precast concrete elements or for industrial processes.

The distinction between trade and non-trade cement is primarily based on the distribution channels and the nature of the transactions rather than any inherent difference in the cement itself.
