Why does Namibia import bulk sulphur instead of finished sulphuric acid?

Elemental sulphur contains roughly three times the acid equivalent per unit of shipping weight (1 tonne of sulphur produces approximately 3 tonnes of pure sulphuric acid). Shipping solid granular sulphur in bulk dry bulkers to Walvis Bay and burning it on-site at the mines is vastly safer, cheaper and more efficient than shipping liquid sulphuric acid in chemical tankers.

What vessel sizes can discharge sulphur at Walvis Bay?

Namport's commercial harbor at Walvis Bay can handle bulk carriers up to 14.0 m draft at the new container/bulk terminals, though sulphur is typically received in geared Handysize and Handymax vessels (20,000 to 35,000 DWT) utilizing 4 x 30 MT ship cranes and grabs.

What environmental and safety controls apply to sulphur at Walvis Bay?

Because sulphur can generate dust during grab discharge, port regulations require low-dust granular form (such as KazMunayGas, ADNOC, or North American formed granules). Water misting and environmental dust screens are deployed during hopper transfer to prevent windblown loss and fire hazards.

Can CBIL arrange the ocean freight and delivery terms to Namibia?

Yes. CBIL provides CIF or CFR Walvis Bay quotations with chartering managed through LaycanDesk, coordinating load laycans, voyage speed, and demurrage/despatch agreements aligned with Namport terminal working hours.

Bulk granular sulphur through the Port of Walvis Bay for Namibia's major uranium leach acid plants

Namibia's uranium mining sector in the Namib desert is one of the world's most consistent consumers of sea-borne elemental sulphur under HS 2503.00, importing approximately 200,000 to 250,000 tonnes annually. Large-scale open-pit and processing operations, including the Rössing and Husab uranium mines, operate dedicated on-site sulphur burning sulphuric acid plants. Sulphuric acid is the primary leaching reagent used to extract uranium oxide (U3O8) from alaskite granite ore, creating sustained demand for high-purity granular sulphur.

All sulphur imports enter through the Port of Walvis Bay, managed by the Namibian Ports Authority (Namport). Cargo discharges at dedicated bulk berths equipped with automated bagging or bulk road/rail transfer corridors that haul the material 65 to 90 km inland to the mine sites in the Erongo region. Under Namibian Customs (NamRA), industrial sulphur for mining operations clears with a 0% MFN customs duty. CBIL supplies bright yellow granular sulphur (99.5% purity minimum, mechanical granular form, moisture < 0.5%, ash < 0.05%) in 20,000 to 35,000 MT Handysize and Supramax shipments, backed by SGS or Intertek certificates of sampling and analysis at the loading port.
