Duty is the duty Census calculated on this month's imports for consumption from each country, as a share of their customs value. It applies the rates in force, additional duties such as Section 301, 232 and IEEPA included and claimed trade-agreement preferences netted out, so it is an observed rate rather than a statutory one. It is an estimate, not duty collected: antidumping and countervailing duties, fees and later refunds are not in it. YoY compares year-to-date value with the same months last year.
