Portland Cement (Other Than White)

Gray Portland cement — the workhorse binder of the construction industry — is classified under tariff line 2523290000 when it is not the white variety. Demand for imports fluctuates with domestic construction cycles and regional capacity constraints, particularly in coastal markets where ocean freight from Canada, Turkey, and Vietnam is competitive. Canada is the top supplier, with Turkey and Vietnam also holding significant positions; Greece and Egypt round out the leading source countries. Importers should confirm whether specific origins carry antidumping or countervailing duty exposure, as gray Portland cement has been the subject of trade-remedy investigations.
