3917
Tubes, pipes and hoses and fittings therefor (for example, joints, elbows, flanges), of plastics
Analysis
Heading 3917 of the Harmonized Tariff Schedule covers tubes, pipes and hoses and fittings therefor (for example, joints, elbows, flanges), of plastics. It divides into 10 six-digit subheadings and 12 eight-digit tariff lines, with 23 ten-digit statistical suffixes below them.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 3917.10.10 (of cellulosic plastics materials).
1 of its 12 lines with a percentage rate are duty-free at the general rate (8%) and 11 are dutiable, from duty-free up to 6.5%. The median line pays 3.1%.
Its median rate of 3.1% sits at the 21st percentile of the headings in chapter 39.
The largest subheadings are 3917.10 (artificial guts (sausage casings) of hardened…, 3 lines), 3917.21 (unnamed, 1 line), 3917.22 (unnamed, 1 line) and 3917.23 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Rubber and Plastics Hoses and Belting Manufacturing (326220), Plastics Pipe and Pipe Fitting Manufacturing (326122) and Unlaminated Plastics Profile Shape Manufacturing (326121). Those are the NAICS industries a US producer of these goods would report under.
