What the HTS is
The Harmonized Tariff Schedule of the United States classifies every product imported into the US. It is law, and the US International Trade Commission maintains it. Each code has 10 digits: the first six are the international HS code, the next two set the US duty rate, and the last two are for statistics.
Where these codes come from
The lookup searches the same copy of USITC’s schedule that the Ebbrate shipment form uses, with each code’s full description path. The date the copy was taken is shown above the results. USITC revises the schedule many times a year, so confirm the code on USITC before you rely on it.
Why the lookup shows no duty rate
The schedule’s general rate is only part of what most imports pay. Goods from many origins carry additional duties under Section 301 or other measures, listed in chapter 99 rather than beside the code. Rather than show a rate that looks exact and is not, each result links to the code on USITC, where the rate and its footnotes are.
Checking how a code is used
CBP publishes its rulings on how goods were classified. Each result links to the rulings that mention its code, so you can compare your goods with ones CBP has already decided. For certainty on a new product, ask CBP for a binding ruling.
Goods that need extra care
When a code falls in a sector US customs has named a priority under the Uyghur Forced Labor Prevention Act, the result says so. Goods outside those codes are still covered if any input comes from Xinjiang.
From the HTS code to a price
The HS code field on the Ebbrate shipment form searches the same schedule. Carriers use the code to price duty on duty paid bids, and every such bid shows the duty on its own line.
