Markets abroad

Each country's own import figures for this product, from UN Comtrade: the 8 biggest importers outside the US in the latest year each has reported, what they bought from the US, and the change from the year before. Values usually include freight and insurance to the importer's border, so they run a little above US export figures. Countries report a year or more late; 57 have reported 2025 so far. Where a country's figure for imports from the US is under half or over double what the US recorded exporting there that year, the US figure is shown under it.

About these figures
  • Source: US Census Bureau international trade data, not seasonally adjusted, in US dollars. Retrieved November 3, 2026.
  • US imports are general imports at customs value, which excludes freight and insurance. Exports are at free-alongside-ship value.
  • Average price is customs value divided by quantity (kilograms), across all of the product's 10-digit lines.
  • Duty paid is the duty Census calculates on each country's imports for consumption, as a share of their value. It moves with tariff changes, exemptions and the mix of goods within the product.
  • Landed cost adds Census's import charges (freight, insurance and other costs of bringing the goods to the first US port) and calculated duty to the customs value, per unit, across the product's 10-digit lines. It leaves out antidumping and countervailing duties, customs fees and transport inland. Prices are averages across the goods within the code, so a lower one can mean cheaper goods, not the same goods for less.
  • Markets abroad are each country's imports as it reports them to UN Comtrade, in US dollars, usually including freight and insurance. Countries report a year or more late and in their own edition of the HS codes, so one still on an older edition is missing for codes that changed in 2022.
  • Tariff notices are from the Federal Register, matched to this product by the HTS numbers in their text.
  • Census revises recent months, so figures can change slightly. These are estimates for research and planning, not customs or legal advice.
