Supply chain cost explosion from sudden tariff implementation with no negotiation pathway

Importers and manufacturers sourcing from Canada face immediate 50% tariff increases with no clear resolution timeline, forcing them to absorb massive cost increases, renegotiate supplier contracts, or find alternative sourcing—all while retaliatory tariffs create cascading price pressures. Current solutions (tariff consultants, supply chain software) are reactive and don't address the core problem of sudden policy-driven margin compression with no predictability.
