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 (tonnes), 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.
- 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.
