Durable/non-durable good industries How to define durable/non-durable good industries? For example, is the industry of  Wholesale and retail trades defined as durable good industry? Thanks in advance.
The US BEA defines durable goods as those lasting three years or more:


  PCE is classified by   type of product as follows. Goods consist
  primarily   of tangible commodities that can be stored or inventoried,
  but they also include certain intangible products, such as software.
  Durable goods are goods that have an average useful life of at least 3
  years. Nondurable goods are goods that have an average useful life of
  less than 3 years. Services are commodities that cannot be stored or
  inventoried and that are usually   consumed at the place and time of
  purchase. ... Durable goods [include]: motor vehicles and parts, furnishings and
  durable household equipment, recreational goods and vehicles, and
  other durable goods.
