Zero child-resistant closures on either shelf, and the catalog holds 71.

The measured position

The main shelf is 443 containers and 206 closures and the dropper shelf is 60 containers and 186 closures. Not one closure on either is child-resistant, and these are products kept in kitchens and bathrooms.

The catalog does hold them

Seventy-one child-resistant closures across ten neck finishes, including 24-410 with 15 and 38-400 with 11. Those are the two largest finishes on the main shelf, which carries 196 containers on 24-410 and 70 on 38-400.

Why they do not appear

Our closure fit data does not carry the pairing for the child-resistant family, so the shelf builder has nothing to show. It is a derivation gap rather than a stock gap and it is recorded as an open task.

Whether one is required is a separate question

The child-resistant packaging rules work by named substance and threshold, and a given veterinary product may or may not be caught. The absence of a requirement is not an argument against a closure here.

Because the use case argues for one anyway

A concentrated topical kept where a child or another animal can reach it is a sensible place for a child-resistant closure whether or not a rule compels it. That is a product decision rather than a compliance one.

And a closure is not a package

The standard tests an assembled package against an effectiveness protocol. We sell a component that can be part of a compliant package and we will not describe one as compliant on its own.

So shop them directly and match by full notation

Not by diameter. 24-410 and 24-400 are a digit apart and not interchangeable, which is the ordinary trap and it applies here as everywhere else.

Worth having even where not required

A concentrated topical in a home is a sensible place for a child- resistant closure on its own merits. Treating the rules as the only reason to fit one is the wrong frame for a product used around children and animals.
