Employment in marketing, storing, distributing, and packing for
shipment of the aquatic commodities described in section 13(b)(4) is, as
such, exempted from the overtime pay provisions of the Act. This means
that the employees actually employed in such operations on the named
commodities are within the exemption without regard to the intimacy or
remoteness of the relationship between their work and processing
operations also performed on the commodities, so long as any prior
processing has not rendered the commodity nonperishable (as in the case
of a canned product) and therefore removed it from the category of
marine products referred to by section 13(b)(4). If the commodity has
previously been rendered nonperishable, the marketing, storing,
distributing, or packing for shipment of it by an employee can come
within the exemption only if the activity is one performed by his
employer as an integrated part of a series of the named operations which
commenced with operations on the perishable marine products to which
section 13(b)(4) refers. Some examples of this situation are given in
Secs. 784.146 and 784.151.
