A rule that waits to be triggered
On this page11
The part creates no obligation to say anything
There is no requirement to state an origin, no panel, no type size and no prescribed words. A product that says nothing about where it came from never engages this rule.
Which puts it in a small group among the spines described here
Almost every other rule in this library compels a disclosure. A net weight, a fiber content, a hazard statement, a care instruction, two words on a drum. The obligation arrives whether or not anybody wanted to speak.
Four postures are now collected and they are genuinely different
A rule can compel a disclosure, suppress a true one, rule a particular word inadequate, or govern a claim somebody volunteered.
Suppression is the textile fiber rules
A fiber present in less than five percent of the total fiber weight may not be designated by its generic name and must be called other fiber. An accurate statement, prohibited.
Ruling a word inadequate is the jewelry guides
The use of faux to describe a laboratory-created or imitation stone is not an adequate disclosure. Nobody is forbidden to write it and writing it accomplishes nothing.
And governing a voluntary claim is this rule and one other
This part, and the Lacey Act false labeling offense. Both are silent until somebody says something, and both then test what was said.
Which has a consequence worth stating for anybody writing copy
The safest position under this rule is silence, and the rule is comfortable with that. It is not trying to get origin information to a buyer; it is trying to make sure that what is said is supportable.
The prohibition is framed through the Federal Trade Commission Act
An unfair or deceptive act or practice within the meaning of section 5(a)(1). So the part is a specification of when a particular claim becomes a section 5 violation rather than a freestanding labeling regime.
And it applies in connection with promoting or offering for sale
Which is wider than labeling. Promoting or offering for sale reaches advertising and solicitation, not only what is printed on a product, and the mail order section makes that explicit.
That wider reach is why this part is the right one to close this library on
Because the definition it gives of a mail order catalog is a definition of what this whole library is, and the containers section is about what that implies.
