4. Ignoring Market Volatility: Copper prices fluctuate. Failing to monitor market trends, secure long-term contracts when advantageous, or build inventory buffers can leave businesses vulnerable to sudden price spikes or shortages.
5. Overlooking Ethical and Environmental Standards: With increasing scrutiny on supply chains, ignoring a supplier’s ethical sourcing practices or environmental record can lead to significant reputational damage and potential regulatory issues. Ensure partners align with your company’s values and compliance requirements.

By proactively addressing these potential mistakes, businesses in Iowa City and throughout the United States can build more robust, reliable, and cost-effective copper supply chains for 2026 and beyond.
