8407.90.10

Analysis

HTS 8407.90.10 covers to be installed in agricultural or horticultural machinery or equipment under heading 8407 (spark-ignition reciprocating or rotary internal combustion piston engines). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in number of items.

Within this group the rate runs from duty-free to 2.5%. Compared with 8407.34.48 (to be installed in vehicles of subheading 8701.21, 8701.22, 8701.23…), which pays 2.5%, a misclassification either way moves the duty by 2.5 percentage points.

The normal trade relations rate here is zero, shared by about 61% of the 823 tariff lines in chapter 84, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

Census statistics map these goods to NAICS 333618 (Other Engine Equipment Manufacturing), an industry of 263 US establishments employing 42,686 people. That concordance is how imports of this line are compared with US output.

The ten-digit suffixes separate less than 4,476 W and air-cooled. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
