The closure measures. Which makes it a component rather than a lid.
What a dropper assembly is
A closure with a pipette through it, usually graduated. 41 of the 215 closures in this group are one, with 3 euro droppers, 1 dropper tip cap and 2 orifice reducers alongside.
And it is the measuring device
Which is unusual. On almost every other shelf in this catalog the closure seals and the contents are measured some other way.
So the fill volume is not the dose
A 30 mL bottle is 30 mL of product and some number of pipette draws, and the second number depends on the pipette rather than the bottle.
Which puts the neck finish at the center
A dropper is specified by neck, and the droppers here sit at 23 on 20-400, 9 on 18-400, 5 on 24-400, 3 on 18MM and 3 on 22-400.
And the containers concentrate at 20-400
31 of 74, which is the dominant neck on this shelf and the one with 23 droppers available. That pairing is genuinely well stocked.
Pipette length matters as much as neck
A pipette too short for the bottle cannot reach the last of the product and one too long bottoms out. Height is published on these containers, which makes the check possible.
Glass pipette or plastic
A glass pipette suits an alcohol extract and resists a terpene load. The bulb is the part that perishes and it is the part to ask about.
Orifice reducers are the alternative
2 of 215. A reducer turns a narrow-neck bottle into a drop dispenser without a pipette, which suits a product dosed by count rather than by volume.
Graduation is a label question as well
A graduated pipette implies a measurement the user is expected to read, and whatever is printed on it has to agree with whatever is printed on the carton.
None of which touches the beverage standard
A measured dose from a graduated pipette does not make a formula unfit for beverage purposes. Formulas are examined.

The droppers sit at 23 on 20-400, 9 on 18-400, 5 on 24-400, 3 on 18MM and 3 on 22-400; the child-resistant closures at 8 on 20-400, 5 on 24-400, 4 on 33-400 and 1 each on 38-400 and 28-400.

27 CFR 17.131: "formulas on TTB Form 5154.1 shall be examined and, if found to be medicines, medicinal preparations, food products, flavors, flavoring extracts, or perfume which are unfit for beverage purposes and which otherwise meet the requirements of law and this part, they shall be approved for drawback." Part 17 is a drawback provision 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 a particular product is within its scope.
