U.S. imports of Uncoated Paper & Paperboard, 225 g/m² or More, Rolls or Sheets (NESOI) (HS 480593) totaled $13.6M in August 2026, imported from 26 countries.
Importers of Uncoated Paper & Paperboard, 225 g/m² or More, Rolls or Sheets (NESOI) paid $461K in duties in August 2026, an average duty rate of 3.39% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Uncoated Paper & Paperboard, 225 g/m² or More, Rolls or Sheets (NESOI) imports of $13.6M in August 2026 ran 12% above the year-to-date monthly average of $12.2M.
Last updated: August 2026 dataAt 225 g/m² and above, uncoated paperboard transitions into heavier structural grades used in packaging cores, wet-process board, and heavy-duty linerboard applications. Eight 10-digit tariff lines subdivide this heading, including wet machine board (4805934015), tube and core board (4805934050), and linerboard with less than 80% chemical sulfate wood pulp (4805934030), alongside folding carton board, construction paper, pressboard ex-kraft, and two NESOI catch-all lines. Canada is the leading import source, with Germany and France also supplying meaningful volumes. The heavier basis weight of these grades means freight economics and mill-specific specifications often drive sourcing decisions as much as duty rates.

Wet machine board is produced by a wet-forming process that bonds multiple plies on the paper machine itself, rather than by laminating pre-formed sheets with adhesive. This structural distinction separates it from composite paperboard under heading 4807 and from pressboard, and it is specifically called out at the 10-digit level precisely because the manufacturing method affects end-use performance in packaging and industrial applications.
The linerboard line (4805934030) applies specifically to board with less than 80% chemical sulfate (kraft) wood pulp. If the pulp composition meets or exceeds that threshold, the product would classify under a different heading entirely. For boards that do not meet any named grade description, the NESOI lines 4805934055 or 4805934060 apply, with the correct choice depending on whether the product falls under a relevant chapter note. A licensed customs broker can help verify pulp-composition documentation and select the correct statistical suffix.
