(a) Except as otherwise provided in this chapter, a commodity in package form introduced or delivered for introduction into or received in intrastate commerce, kept for the purpose of sale, or offered or exposed for sale in intrastate commerce shall bear on the outside of the package a definite, plain, and conspicuous declaration of

1. (1) the net quantity of the contents in terms of weight, measure, or count;
2. (2) in the case of a package kept, offered, or exposed for sale, or sold in a place other than on the premises where packed, the name and place of business of the manufacturer, packer, or distributor; and
3. (3) the identity of the commodity in the package unless it can easily be identified through the wrapper.

(c) Under (a)(1) of this section the director shall, by regulation, establish

1. (1) reasonable variations or tolerances to be allowed, which may include variations below the declared weight or measure caused by ordinary and customary exposure, only after the commodity is introduced into intrastate commerce, to conditions that normally occur in good distribution practice and that unavoidably result in decreased weight or measure;
2. (2) exemption as to small packages; and
3. (3) exemptions as to commodities put up in variable weights or sizes for sale to the consumer intact and either customarily not sold as individual units or customarily weighed or measured at the time of sale to the consumer.
