Saying so is the honest move. The alternative is borrowing an authority that does not apply.

What is not regulated here

Reed storage, rosin storage, string storage and mouthpiece storage. No federal rule governs any of them, and there is no model code or consensus standard doing the job either.

Which is unusual in this library

Most properties here open with a quoted regulation because most crafts have one. A property that pretended to would be inventing the thing this catalog exists not to invent.

So the content is physics and measurement

How cane behaves when it is wetted and dried, what oxidises a string, where rosin dust goes, and what the shelf actually holds. All of it checkable, none of it quoted from a rulebook.

The one exception is the oil

White mineral oil has a federal definition and a set of tests behind it, and it is the difference between a specified grade and whatever oil was to hand.

Which matters because of where it ends up

A brass player blows air through the instrument the valve oil is in, and cork grease goes on a joint that meets a mouthpiece. The contact is incidental and it is real.

We do not claim a food rule applies

21 CFR 172.878 is a food additive provision and an instrument lubricant is not a food. What the section gives is a published specification for the grade, which a manufacturer can meet or not.

That is a question to ask, not an answer to assert

Does this oil meet the white mineral oil specification. A maker who knows will say; one who does not has told you something.

Six leaves, two halves

Four dry storage problems and two lubricants. The archetype describes the four and the oil section covers the two.

The shelf has one specific absence

No tins and no steel at all. The traditional rosin and cork grease container is a small tin, and there is not one in this group.

Read the physics section for what actually matters

Because in the absence of a rule, the material behaviour is the whole of the subject, and it is more useful than a borrowed regulation would have been.

References

No federal regulation governs reed storage, rosin storage, string storage or mouthpiece storage as such. This property states that rather than borrowing an authority from a neighbouring craft, and the content for those four leaves is material behaviour and measured catalog facts rather than quoted law.

21 CFR 172.878: "White mineral oil is a mixture of liquid hydrocarbons, essentially paraffinic and naphthenic in nature obtained from petroleum." It must meet the United States Pharmacopeia test for readily carbonizable substances, the U.S.P. requirement for sulfur compounds, and the specification published in the Journal of the Association of Official Analytical Chemists. This section is a food additive provision; it is cited here as the published definition of the grade, not as a rule applying to instrument lubricants. law.cornell.edu

Written from 21 CFR 172.878 and from the catalog as it stood on 19 October 2026. Nothing here says a food-contact regulation applies to an instrument lubricant; 172.878 is cited as the published specification for white mineral oil, which is the benchmark a manufacturer can either meet or not. The other four leaves have no governing regulation and this property says so rather than borrowing one.
