The container is an authorized substitute

The requirement
Every article of foreign origin, or its container as provided in a further subsection, must be marked to indicate to an ultimate purchaser in the United States the English name of the country of origin of the article.
And the parenthesis is the finding
Or its container. The statute offers the package as the place the mark may go, in the same breath as the requirement.
Which is unique in this library
Every other spine here requires the package to carry something of its own. This one says the package may stand in for the article.
And it is exactly right for this group
You cannot mark a resistor. Or a ferrule, a splice cap, a solder pellet, a crimp terminal or a wire nut.
Sixteen named articles and not one is markable
Butt connector, cable clip, crimp terminal, diode, ferrule, two kinds of fuse, heat shrink, LED, resistor, ring terminal, solder pellet, spade terminal, splice cap, toggle switch and wire nut.
The marking standard is demanding
As legibly, indelibly, and permanently as the nature of the article or container will permit. Three adverbs, all of them hard on a 2 mm component.
Which is why the proportionality clause matters
As the nature of the article or container will permit. The standard bends to the object, which is the opposite of a fixed type size.
The cannabis topicals property is the contrast
There, 21 CFR 740.2(a) sets a 1/16 inch minimum that does not bend for a small package, and the only relief is petitioning for a rulemaking.
Two schemes, two attitudes to a small article
One bends and one does not, which is worth knowing before assuming a marking rule is either flexible or rigid.
And there is a third tier
An exception where an article is incapable of being marked, which the Secretary of the Treasury may authorize.
So three tiers in one section
Mark the article, mark the container, or be excepted. A small part sits in the second or third and almost never the first.
Then our own position, and it is narrow
The 251 containers on this shelf are 117 PET, 78 polypropylene and 56 glass, and we publish no marking or printing service at all.
So the container is the authorized place and we supply the container only
The mark goes on by some process we do not provide, which is the honest division.
