8408.90.10

Analysis

HTS 8408.90.10 covers to be installed in agricultural or horticultural machinery or equipment under heading 8408 (compression-ignition internal combustion piston engines (diesel or semi-diesel engines)). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in number of items.

This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.

Rates on the nearby lines range from duty-free to 2.5%. The costliest confusion would be with 8408.20.90 (engines of a kind used for the propulsion of vehicles of chapter 87…) at 2.5%, a difference of 2.5 points on the customs value.

For statistics it divides in two: 8408.90.10.40 for not exceeding 37.3 kW and 8408.90.10.80 for exceeding 37.3 kW. Both pay the same duty; the suffix records which kind was imported.

There is no general-rate duty on this line, which puts it with roughly 61% of the 823 tariff lines in chapter 84 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
