Four of the five are extracts. The fifth is a carrier oil and behaves differently.

CBD and CBN tinctures

Named for a single cannabinoid, which implies a characterized extract rather than a whole-plant one. From a container point of view they are the same problem: a small volume, dosed by dropper, kept out of light.

THC tincture

Same packaging problem and a different regulatory world, governed by state cannabis programs this property does not describe.

Full spectrum oil

A whole-plant preparation carrying the terpene fraction, which makes it the most light-sensitive and most volatile of the five. Amber or blue glass and a tight closure.

MCT blend

A carrier oil rather than an alcohol extract, which changes the questions. No spirits, so no drawback question, and a different interaction with the closure liner.

Alcohol and oil behave differently in a bottle

Alcohol wets a thread and creeps, and it attacks some liner materials. An oil does neither and instead leaves a film that makes a cap feel loose.

Which is why the liner matters and is barely recorded

Only 2 of the 74 containers in this group carry a liner value and both read No Liner. The other 72 are blank, which is an absence of data rather than a claim.

All 74 containers are glass

Which is the right answer for all five leaves. An alcohol extract in polypropylene is a chemistry question nobody needs to have.

Boston rounds dominate

60 of the 69 bottles. A narrow neck, a thick shoulder and a shape every dropper in the world was designed around.

Capacity is small and clusters low

10 to 120 mL with a median of 30, and 30 containers over an ounce. Which is the right window for a dosed product.

The shelf is genuinely good here

Unlike three of the four other cannabis groups, this archetype and this shelf match. The problems are fit and case size rather than suitability.

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. law.cornell.edu

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.
