A detailed breakdown of how import duties compound across your P&L and practical approaches to protect your margins.
A tariff is not simply a percentage off your margin—it compounds across your cost structure. A 25% tariff on a $10 FOB product increases COGS to $12.50. If you maintain your selling price, margin shrinks. If you raise prices to maintain margin, conversion rates typically drop 2-5% for every 10% price increase, reducing total revenue. Either path costs money.
Private label sellers absorb the full tariff impact since they control no part of the supply chain pricing. Resellers may negotiate with suppliers to share the burden, but factory margins are often already thin. Marketplace sellers face the tightest squeeze because platform fees and advertising costs are fixed percentages that do not shrink when tariffs rise.
Effective margin protection combines multiple strategies: diversifying sourcing away from high-tariff countries, leveraging tariff reduction programs like FTZs and drawback, reclassifying products for lower rates, negotiating with suppliers to share duty costs, and optimizing your pricing strategy to pass through costs where the market allows. No single approach is sufficient—the most resilient businesses use all of them.
Tariffs increase your cost of goods sold (COGS) by the duty percentage applied to the customs value. A 25% tariff on a $10 product adds $2.50 to your landed cost. If your selling price is $25, your margin drops from 60% to 50%—a significant erosion that compounds across your entire catalog.
It depends on your competitive position and price elasticity. Products with strong brand loyalty or few alternatives can absorb price increases. Commodity products in competitive markets may lose volume if prices rise. Many sellers use a blended approach—absorbing some cost and passing through the remainder.
Products sourced from China face the steepest tariffs at 25-35% under Section 301. Categories with the highest effective rates include electronics, furniture, auto parts, apparel, and industrial machinery. Products from USMCA-qualifying countries face the lowest rates.
Start with your customs value (typically FOB price), apply the effective tariff rate, add any additional Section 301 or Section 122 tariffs, include Merchandise Processing Fee and Harbor Maintenance Fee, then recalculate your margin against your selling price. Do not forget to factor in brokerage fees and compliance costs.
Yes. Import duties are a deductible business expense included in your cost of goods sold. They reduce your taxable income, which partially offsets the cash impact—but only by your effective tax rate, which is typically 21-37%.
