represent products whose manufacturers are likely to require lathe machines. To get a full picture of
all six-digit NAICS industries that might use lathes, the company can (1) determine past customers’
NAICS codes; (2) go through the NAICS manual and check off all the six-digit industries
that might have an interest in lathes; (3) mail questionnaires to a wide range of companies inquiring
about their interest in wood lathes.
