Ten notions and no coverage
On this page10
The group has ten leaves
Bobbin storage, button storage, elastic scrap, hook and eye, needle storage, pin storage, seam ripper tip, snap storage, thread storage and zipper pull.
Four of them are a container problem by name
Bobbin storage, needle storage, pin storage and thread storage are already phrased as storage. The buyer arrives knowing the shape of the answer and is choosing a size and a lid.
Four more are small hardware
Hook and eye, snap, zipper pull and seam ripper tip. These are metal or plated metal, they are tiny, and they come loose in quantities that are awkward in anything with a wide mouth and a shallow floor.
Buttons are their own category and the reason is size spread
A button collection spans roughly four millimeters to forty in diameter and sorting is usually by size or by set rather than by material, which makes a set of small identical jars more useful than one large one.
Elastic scrap is the odd one and it is the only perishable
Rubber and spandex lose elasticity over time regardless of how they are stored, and heat and light accelerate it. It is the one leaf here where the container choice can slow a loss rather than merely organize a pile.
None of the ten is textile wearing apparel
And none is a piece good sold by the piece from a bolt or roll for the purpose of making home sewn apparel. Part 423 does not reach any of them, and nothing on these pages says it does.
Which is the normal situation for a components group
The federal label rules in this library attach to finished goods and to a few regulated substances. A notion is upstream of both.
The connection that does exist is one of sequence
These parts become part of a garment, and the garment then carries a permanent label that must state what regular care it needs. The notion is inside the thing the label describes.
That is a reading of the rule, and the next page labels it as one
The text says care labels must state what regular care is needed for the ordinary use of the product, singular. Whether that has consequences for a component is an argument from the words, not a determination by anybody.
