Where the declaration goes

The principal display panel
The label shall bear the net quantity declaration separately and accurately stated on the principal display panel. That is the face the customer sees in normal retail display, and on a small round jar it is not very much space.
Separated, by a measured amount
From text above or below, by at least a space equal to the height of the lettering used in the declaration. From text left or right, by at least twice the width of the letter N in the type used. Those are real measurements, not a layout suggestion.
A distinct item
It cannot be folded into a sentence of marketing copy or run together with the fragrance name. The point is that a shopper comparing two jars can find the quantity on each without reading the label.
No qualifying words
The section names the kind it means: jumbo quart, giant liter, full gallon, when packed, minimum, or words of similar import. A melt label saying "approx" or "minimum net weight" has used exactly the construction the rule forbids.
Conspicuous and contrasting
500.20 requires boldface type or print in distinct contrast to other matter on the package, by typography, layout, color, embossing or molding. Low-contrast small type on a textured label is the usual way this is missed.
And the identity statement sits alongside it
500.4 requires the principal display panel to specify what the commodity is, as a principal feature, in the common or usual name. "Wax melt" is that name; a fragrance name on its own is not.
Small round jars make this genuinely tight
On a 60 ml jar the principal display panel is a few square inches and the declaration needs its own space with measured clearance around it. That is a real constraint on the artwork, and it is easier to design for than to retrofit.
