4805.93.40

Analysis

HTS 4805.93.40 covers weighing 225 g/m² or more: other under heading 4805 (other uncoated paper and paperboard, in rolls or sheets, not further worked or processed…). US Customs collects import statistics for it under 6 ten-digit suffixes, reported in kilograms.

The normal trade relations rate here is zero, shared by about 100% of the 225 tariff lines in chapter 48, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

Goods from countries without normal trade relations pay the column 2 rate of 30% instead of nothing, so origin decides between free entry and a 30% duty.

The ten-digit suffixes separate folding carton board, wet machine board, construction paper, linerboard containing by weight less… and tube and core board. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.

Census statistics map these goods to NAICS 322130 (Paperboard Mills), an industry of 179 US establishments employing 38,290 people. That concordance is how imports of this line are compared with US output.
