215 closures, and 13 containers with none.

The totals were read as coverage

215 closures against 74 containers looks like three options each. The distribution is nothing like that.

An 18DIN bottle was chosen

12 of them here and no 18DIN closure in the group. The most on-category neck on the shelf is the one with nothing to fit it.

Or a 43-485 bottle

One container, no closure. A single orphan is easy to miss in a list of 74.

A dropper and a child-resistant cap were both expected

41 droppers and 19 child-resistant closures, in separate families with no overlap. Both functions exist and the combined article does not.

Pipette length was not checked against bottle height

A dropper is specified by neck and a pipette has a length. Height is published on these containers, so the check is available and it is easy to skip.

Full case only was discovered at the end

71 of 74 containers here are full case only, which is the most extreme in the library. The right bottle at the wrong case size is still a problem.

Quote only was read as unavailable

20 of 74. The price is not published, which means a conversation rather than a dead end.

Clear glass was chosen for a full spectrum oil

20 clear containers here against 42 that offer real protection. This is the one cannabis shelf where the protective choice is the easy one, and clear is still available.

A liner was assumed because the field was blank

72 of 74 containers have no liner value and 2 read No Liner. A blank is an absence of data, so the answer is to ask.

Height was not read for the dropper

Which is a second version of the same skipped check. The 20-400 pairing is well stocked and a pipette still has to reach the bottom of a 120 mL bottle and not bottom out in a 10 mL one.

Check neck first, then case size

Those are the two that end a build, and both are published on the product page.

The Davis Pack Supply catalog, measured 19 October 2026. Twelve of the 74 containers in this group carry an 18DIN neck and there are no 18DIN closures on this shelf, so a sixth of it cannot be closed from it. One further container at 43-485 also has no matching closure. In the other direction, 38 closures fit the 3 containers at 38-400, 30 fit the single container at 33-400, and 21 fit the 2 at 24-410.

Written from 27 CFR 17.131 and 17.132 and from the catalog as it stood on 19 October 2026. Part 17 is a drawback provision, a mechanism for recovering federal excise tax on distilled spirits used in nonbeverage products. It is a tax rule rather than a safety or packaging rule, and nothing here states whether any particular product is within its scope. Availability, quote-only and full-case figures are a single snapshot rather than a trend. The twelve 18DIN containers on this shelf have no matching closure on it.
