Tariffs and duty rates change without warning, and the morning they do, some products quietly sell below your target margin. MarginGuard watches US and EU duty schedules (USITC HTS, Section 301/232/122, EU TARIC) and resolves the real import duty on each SKU from its HS code, origin, and unit cost. When a rate change pushes a product under your margin, you get the affected SKUs and the exact price to recover. It is advisory and read-only, and never edits your prices.

• Resolves each SKU's true duty: USITC HTS base plus Section 301, 232, and 122
• Flags any product whose margin falls below your target after a rate change
• Hands you the exact price to charge to restore your target margin per SKU
