Analysis
HTS 8442.40.00 covers parts of the foregoing machinery, apparatus or equipment under heading 8442 (machinery, apparatus and equipment (other than the machines of headings 8456 to 8465)…).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 61% of the 823 tariff lines in chapter 84. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other lines in the same group are 8442.30.01 (machinery, apparatus and equipment, duty-free), 8442.50.10 (plates, cylinders and other printing components; plates…, duty-free) and 8442.50.90 (plates, cylinders and other printing components; plates…, duty-free).
Census statistics map these goods to NAICS 33324 (Industrial Machinery Manufacturing), an industry of 2,836 US establishments employing 111,497 people. That is the industry code a US manufacturer of the same product would normally use.
All 3 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
