They retain their natural vesicular texture and are not subjected to any processing beyond cutting, aligning with the crude state requirement of Chapter 25. This tariff item covers pumice stone in its natural or minimally processed form.
Crude Pumice Stone Blocks
Crude pumice stone blocks are large, unprocessed blocks of natural pumice extracted directly from volcanic deposits, remaining in their crude form without further shaping or sizing. They are not heat-treated or subjected to any processing beyond extraction, and fall under this tariff item as crude pumice. The blocks are suitable for further abrasive processing.
Crushed Pumice Stone for Abrasive Cleaning
Crushed pumice stone is a naturally occurring volcanic rock processed by crushing and screening for use as an abrasive in cleaning applications. It is classified under tariff item 2513.10.00 as pumice stone, which includes natural abrasives whether or not heat-treated, provided no further processing beyond mechanical means has occurred.
Crushed Volcanic Pumice Chunks
