"sell by" implies there is some shelf life after the sale . . .
"best by / use by" is the manufacturer's determination of when the product quality declines due to age;
those dates are determined at the sole discretion of the manufacturer -
except for shell eggs(*) -
and in many states, local/state laws for dairy products - which are especially prone to spoilage . . .
"expires" is rarely seen in USA except for baby formula - where it is a legal requirement.
if you need a good laugh, check the boxes of salt in the grocery store.
a box of salt - which has been mined from deposits millions of years old . . .
shows up with a "best by" date ~2 years out . . .
(*) eggs:
#1 - only the packing date is required by law - which is typically in Julian date for i.e. last year digit + day of year 'count'
USDA Grade 'regs&stuff' do not require egg cartons to show in plain text a "sell by" or "use by" date.
#2 - however comma and all that . . . IF "sell by" or "use by" dates are printed in plain format on the carton:
the "sell by" date may not be more than 30 days from the "pack date"
the "use by" date may not be more than 42 days from the "pack date"
sailors, who pack fresh eggs in water glass, to be consumed months and month and months later in their voyage . . .
