Analysis
HTS 4001.21.00 covers natural rubber in other forms: smoked sheets under heading 4001 (natural rubber, balata, gutta-percha, guayule, chicle and similar natural gums, in…). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.
The normal trade relations rate here is zero, shared by about 39% of the 142 tariff lines in chapter 40, 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 other lines in the same group are 4001.10.00 (natural rubber latex, whether or not pre-vulcanized, duty-free), 4001.22.00 (technically specified natural rubber (TSNR), duty-free), 4001.29.00 (natural rubber in other forms: other, duty-free) and 4001.30.00 (balata, gutta-percha, guayule, chicle and similar natural…, duty-free).
Census statistics map these goods to NAICS 113210 (Forest Nurseries and Gathering of Forest Products), an industry of 185 US establishments employing 932 people. That concordance is how imports of this line are compared with US output.
