A 473 mL jar is not a 473 gram jar.
Our capacity was read as a fill weight
It is a volume in millilitres. A powder is declared in grams and the two are connected only by a bulk density we do not publish.
And a density was assumed
Which produces a label quantity that is wrong by whatever the assumption was wrong by. One filled jar on a scale settles it exactly.
A light botanical adaptogen and a dense colostrum are different masses in the same jar. The conversion is per product.
The settled volume was not measured
A powder packs down in transit, so the fill at the filler and the level a consumer sees are different numbers.
And the scoop was left out of the arithmetic
It occupies headspace and is not product. Whether that space is functional depends on which slack fill definition reaches the product.
The ounce sizes were read as metric
237, 473 and 946 mL are 8, 16 and 32 fluid ounces. Treating them as round metric figures produces odd declared quantities.
A tall jar was chosen for a scooped product
Diameter runs 1.8 to 5.7 inches and height 1.48 to 9.99. A 9.99 inch jar at 1.8 inches across is not a scoopable container.
The mouth was not checked against the scoop
108 of 171 are 70 mm or wider and 63 are not. The scoop is a physical object with a width.
And the liner was left unspecified
35 of the 290 closures are recorded as No Liner and 27 have nothing recorded. A hygroscopic powder in an unlined jar cakes.
And the gummies property was read as covering this shelf
389 of these 461 rows are shared with it, and that property is written on the Supplement Facts surface-area thresholds rather than on mass and volume. Both apply and neither replaces the other.
Weigh, then settle, then choose
Three steps, and the container is the least reversible of them.

The Davis Pack Supply catalog, measured 19 October 2026. Our capacity field is a volume in millilitres, published on 169 of the 171 containers in this group and running 100 to 3,000 mL with a median of 355. A powder supplement is declared by weight. We publish no bulk density and no fill weight, so a volume cannot be converted to a mass from our data. Bulk density is a property of the powder, and the five leaves in this group differ widely in it.

15 U.S.C. 1454(c)(4), requiring regulations effective to "prevent the nonfunctional-slack-fill of packages containing consumer commodities", with the statutory definition: "a package shall be deemed to be nonfunctionally slack-filled if it is filled to substantially less than its capacity for reasons other than (A) protection of the contents of such package or (B) the requirements of machines used for enclosing the contents in such package." The FDA regulation at 21 CFR 100.100(a) gives six functional reasons rather than two; the pet food and treats property quotes all six.
