A label that must outlive the product
On this page10
The definition does the work here
A care label means a permanent label or tag containing regular care information and instructions, attached or affixed so that it will not become separated from the product and will remain legible during the useful life of the product.
Three requirements are packed into that
Permanent. Will not separate. Will stay legible. The third is the one that is easiest to fail quietly, because a printed label can survive forty wash cycles structurally and still be unreadable.
And the measuring stick is the product, not a period of time
Useful life of the product. Not two years, not a stated number of washes. The durability requirement is relative to the thing it is attached to, so a heavier garment demands a longer lasting label.
This is the only permanent label requirement across this library
Every other federal label rule here governs a container, and a container is discarded. A food panel, a hazard label, a volume statement: they need to last until the package is empty.
Which makes the care label a different kind of object
It is not communication about a transaction. It is a set of instructions that has to be available at every future washing, including the ones that happen after the garment has changed hands.
Regular care is also a defined term and it excludes one thing
Regular care means customary and routine care, not spot care. So the label is about the washing that will happen repeatedly, not about what to do with a stain.
And the two cleaning processes have definitions with numbers in them
Machine wash is a process using water, detergent or soap and agitation. Dryclean is a commercial process using a common organic solvent, and the definition includes adding moisture to the solvent up to 75 percent relative humidity and hot tumble drying up to 160 degrees F.
A federal definition of a cleaning process that specifies humidity
That is unusual enough to note. The number exists because a drycleaner adds moisture deliberately, and a garment that is harmed by it needs a warning rather than a different solvent.
Which is why the warnings provision reaches the drycleaner too
If any part of the drycleaning procedure that consumers or drycleaners can reasonably be expected to use would harm the product, the label must warn, using do not, no, only or other clear wording.
