Is this for you at all

What this covers
Herbal, mineral, probiotic and vitamin capsules, softgels and tablets. Six leaves, one archetype, and the archetype gets it right: packer bottle, induction seal, desiccant and cotton.
The rule that reaches this format
A dietary supplement containing the equivalent of 250 mg or more of elemental iron from any source in a single package, at 0.05 percent or more weight-to-weight for a solid, needs child-resistant packaging meeting 16 CFR 1700.15.
Two tests, and both have to be met
A mass per package and a concentration. Missing either one takes you out of the requirement, which is why the calculation has to be done properly rather than estimated from the dose on the label.
The mass test is the surprising one
An 18 mg iron dose is ordinary. Sixty capsules of it is 1,080 mg in the package, more than four times the threshold. Even a 14-capsule sample pack is 252 mg, which is over.
So the bottle count is a regulatory decision
Offering a 180-count for better value, or a small trial size, changes the mass in a single package. That is a merchandising choice with a packaging consequence, and it is the specific thing that gets missed.
And our shelf has a gap you should know about
The derived shelf for this format is 157 containers and 211 closures, and none of the 211 is child-resistant. The containers section gives the measured position and what to do about it.
What this property does not cover
The Supplement Facts panel, the structure and function disclaimer, the notification requirement and cGMP are covered in the written sites on Supplements and on Powders. This one is the packaging half.
Why the packaging half deserves its own site
The label and claims side of supplements is well covered elsewhere in this library, and it is where most published advice stops. The count, the seal, the desiccant and the closure are where the money and the recalls are, and they get far less attention.
