What a lookup can return
Every tariff line has a base rate, not every line runs deep
All 13,855 tariff lines in the live HTS extract carry a general (MFN) rate. The deeper layers below, a column 2 rate, HTSUS footnotes, a special preferential rate, exist for a smaller share, so a lookup returns more for some lines than others.
- General (MFN) rate 100% 13,855
The standard duty rate applied to imports from normal-trade-relations countries -- every tariff line carries one.
- Column 2 (non-NTR) rate 97.3% 13,484
The statutory rate applied to imports from a handful of non-normal-trade-relations countries.
- HTSUS footnotes 93% 12,883
Chapter/heading-level notes on scope, exclusions, or special statutory treatment.
- Special (FTA/preferential) rate 65.3% 9,054
A reduced or duty-free rate under a free-trade agreement or preference program, when the line qualifies.
