Tariff = Trade Value x Tariff Rate
Currency Impact = Trade Value x FX Depreciation %

Understanding Brexit Trade Costs

Since January 2021, UK-EU trade operates under the Trade and Cooperation Agreement (TCA). While tariffs are zero for qualifying goods, businesses face new customs declarations, rules of origin requirements, and regulatory checks.

Key Cost Areas

  • Tariffs: 0% under TCA for goods meeting rules of origin; WTO rates (avg 4-5%) otherwise
  • Customs declarations: Estimated £20-50 per declaration for imports and exports
  • Rules of origin: Proving goods qualify for zero tariffs adds admin costs
  • Currency fluctuation: GBP volatility increases cost uncertainty
  • Regulatory divergence: CE/UKCA marking, product standards, food safety checks
