“The contracts we’ve had have protected us up to this point, but certainly at some point in time they start to run out and then renegotiations take place.”
The White Home has not launched particulars of the tariffs, together with whether or not they’ll apply to semi-finished copper merchandise equivalent to wires and rods, and whether or not restrictions on exports of copper scrap may additionally be put in place.
Along with long-term contracts, there was a rush of copper into the US this 12 months on expectations of upper tariffs. Consequently, analysts say finish customers of copper are unlikely to be hit with the total influence till the producers’ personal warehouses run out of their provides.

Barclays estimated {that a} 50 per cent tariff may add as much as $110 to the price of a petroleum car and as a lot as $700 to an electrical automobile for the reason that steel is utilized in wiring harnesses in addition to batteries, motors and inverters.
Nonetheless, the influence is more likely to filter by way of not directly for carmakers, since it’s suppliers that always buy the steel. Trump has additionally promised that the auto business, which faces a 25 per cent tariff on imports of foreign-made automobiles, won’t be stacked with extra levies on the metals.

Nonetheless, copper costs are handed by way of on to clients, primarily based on benchmark costs, and Bifulco acknowledged that increased copper costs may hit demand.
“In our case, we pass through to the customers the raw material prices. So the real impact of the tariff is not on us, it is on the final customers. The raw material price trends tend to influence the demand behaviour.”
