The one rule where the package is in the way
On this page10
Most of this library is about a package that carries a rule
A volume statement, a net weight, a hazard class, an ingredient panel. The container is where the information lives and the rule describes how to put it there.
Part 423 starts from the other side
Care labels must be attached so they can be seen or easily found when the product is offered for sale. The label is on the garment, and the package is a thing that might come between the label and the customer.
And the rule anticipates exactly that
If the product is packaged, displayed, or folded so that customers cannot see or easily find the label, the care information must also appear on the outside of the package or on a hang tag fastened to the product.
Folded is the detail that shows what the rule is worried about
A fold is not packaging. It is a way of presenting a garment that can bury a neck label as effectively as a sealed bag. The rule lists it alongside packaging because the test is whether the customer can find the label, not what kind of enclosure caused the problem.
So the package becomes a remedy for itself
Having obstructed the label, the package is ordered to carry the same information. Which is a sixth distinct relationship between a container and a rule in this library, after the container as the carrier, as the unit, as the labeled element, as irrelevant, and as the regulated article itself.
The alternative remedy keeps the information on the garment
A hang tag fastened to the product. Not permanent, because a hang tag is removed at first wearing, but attached, which means it travels with the garment through the store.
Also means seen or easily found is a two part test
Seen, which is a question about visibility, and easily found, which is a question about where a customer would look. A label that is visible only after unfolding a garment satisfies neither.
And it is the manufacturer and importer who must attach it
The obligation sits upstream of the retailer. A shop that folds a garment badly has not violated this paragraph; the party who packaged or displayed it in a way that hides the label has the duty to duplicate the information.
For a notions shelf this is all context and nothing more
No container in this group is subject to that paragraph. The paragraph is here because it is the only place in this library where a federal rule treats a package as an obstacle rather than as a surface.
