7302.10.50

Analysis

HTS 7302.10.50 covers rails: of alloy steel under heading 7302 (railway or tramway track construction material of iron or steel, the following: rails…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.

The normal trade relations rate here is zero, shared by about 77% of the 250 tariff lines in chapter 73, a useful check when a neighbouring dutiable line is a candidate. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.

Census statistics map these goods to NAICS 331110 (Iron and Steel Mills and Ferroalloy Manufacturing), an industry of 359 US establishments employing 78,532 people. That concordance is how imports of this line are compared with US output.

The ten-digit suffixes separate new and railway rails for rerolling. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.

Goods from countries without normal trade relations pay the column 2 rate of 9% instead of nothing, so origin decides between free entry and a 9% duty.
