2513.10.00

Analysis

HTS 2513.10.00 covers pumice; emery; natural corundum, natural garnet and other natural abrasives, whether or not heat-treated: pumice stone under heading 2513 (pumice; emery; natural corundum, natural garnet and other natural abrasives, whether or…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.

For statistics it divides in two: 2513.10.00.10 for crude or in irregular pieces, including crushed pumice and 2513.10.00.80 for other. Both pay the same duty; the suffix records which kind was imported.

The normal trade relations rate here is zero, shared by about 91% of the 78 tariff lines in chapter 25, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.

The other lines in the same group are 2513.20.10 (crude or in irregular pieces, duty-free) and 2513.20.90 (emery, natural corundum, natural garnet and other natural…, duty-free).

Census statistics map these goods to NAICS 21239 (Other Nonmetallic Mineral Mining and Quarrying), an industry of 236 US establishments employing 10,238 people. That concordance is how imports of this line are compared with US output.
