7325.10.00

Analysis

HTS 7325.10.00 covers of nonmalleable cast iron under heading 7325 (other cast articles of iron or steel). US Customs collects import statistics for it under 6 ten-digit suffixes, reported in kilograms.

This line's footnotes point to one additional provision in Chapter 99: 9903.90.09 (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.

Within this group the rate runs from duty-free to 2.9%. Compared with 7325.99.50 (other: other), which pays 2.9%, a misclassification either way moves the duty by 2.9 percentage points.

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.

The ten-digit suffixes separate manhole covers, rings and frames, catch basins, grates and frames, cleanout covers and frames, valve and service boxes and meter boxes. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
