Copper – Exported from South Africa to Cathay Metals Trading Co. (China)

Challenge

Chinese customs introduced strict new heavy metal thresholds weeks before shipment: arsenic ≤0.45%, lead ≤0.3%. Initial assays from two producers showed arsenic at 0.62% above limit. Rejection would trigger costly reprocessing or demurrage at Durban Port, with $18M/day exposure.

Solution

CM MINING coordinated with three additional certified producers in Rustenburg to source a low-arsenic batch (0.28% As). We blended and homogenized the material on-site under SGS supervision, achieving a final composite of 0.44% arsenic and 27.8% Cu. An independent Intertek report was commissioned and submitted to Chinese import agents 10 days pre-shipment, alongside full chain-of-custody logs and EUDR-aligned origin documentation.

Outcome:
The cargo cleared Shanghai Customs within 22 hours of arrival. Cathay Metals accepted the shipment without adjustment and signed a 12-month off-take agreement for 650,000 MT annually locking in CM MINING as its primary Southern African copper partner.
