The numbers are all correct. Which is what makes them easy to misread.
Exactly 250 returns two rows of 238. The band 225 to 275 returns 57, of which 47 are eight fluid ounces expressed as 236.588. An exact search finds under four percent of the real answer.
Reading 236.588 as a specification
It is eight fluid ounces converted and rounded to three decimals. Nobody designed a 236.588 milliliter jar and nobody will ask for one.
Treating three decimals as three decimals of precision
Eight fluid ounces is 236.5882 milliliters. The stored figure carries the precision of the conversion, not of a measurement of the container, and no page here uses it as one.
Assuming the unit can be inferred from the material or the size
All 71 polypropylene rows are in ounces but PET splits 104 to 13 and glass 40 to 10, and the two systems overlap across nearly the whole capacity range. Only the recorded unit string answers it.
Counting rows as choice
238 containers resolve to 29 distinct capacities, and nine ounce values carry 201 of the rows. The size decision is between about nine options and everything else is a variant.
Storing collets with abrasive discs
A collet is a precision taper and a bore. Discs produce grit. The group separates by kind rather than by size, which is the one storage decision these eight leaves genuinely require.
Expecting a container here to be rated for a chemical or a dust
None is. These are dry storage containers and no page on this property claims a seal, a barrier or a rating of any kind for any of them.
And treating the hazard communication standard as something a jar satisfies
It governs the classification and labeling of hazardous chemicals in the workplace. Its article definition is the spine here because the deciding limb asks what an item releases under normal conditions of use, which is a question about a situation and not about an object. Nothing on these pages answers it for anything.

The Davis Pack Supply catalog, measured 19 October 2026. Searching this shelf at exactly 250 mL returns two rows. Widening to 225 through 275 returns 57, of which 47 are 236.588 mL, which is 8 fluid ounces and sits 5.4 percent below 250. Exactly 500 mL returns two rows and 450 through 500 returns 33. Exactly 100 mL returns two rows and 90 through 130 returns 48. The system a row was recorded in correlates with material but does not follow it: all 71 polypropylene rows are in ounces, while PET is 104 in ounces and 13 in milliliters, and glass is 40 and 10.
The Davis Pack Supply catalog, measured 19 October 2026. Of this group’s 238 containers, the recorded capacity string is in fluid ounces for 215, in milliliters for 21 and in cubic centimeters for 2. The milliliter figure stored alongside it is arithmetic performed on that string: 1 oz becomes 29.573 mL on 4 rows, 2 oz becomes 59.147 on 29, 3 oz becomes 88.721 on 8, 4 oz becomes 118.294 on 44, 6 oz becomes 177.441 on 17, 8 oz becomes 236.588 on 47, 9 oz becomes 266.161 on 6, 12 oz becomes 354.882 on 19 and 16 oz becomes 473.176 on 31, with single rows at 0.75, 1.25, 1.5, 2.2, 8.4, 8.9, 10, 14 and 14.5 ounces. The 23 rows recorded natively carry 15, 30, 50, 55, 75, 100, 125, 150, 200, 250 and 500 milliliters, one or two rows each. There are 29 distinct capacity values across the 238 containers.
29 CFR 1910.1200(c), which defines: "Article means a manufactured item other than a fluid or particle: (i) Which is formed to a specific shape or design during manufacture; (ii) Which has end use function(s) dependent in whole or in part upon its shape or design during end use; and (iii) Which under normal conditions of use does not release more than very small quantities, e.g., minute or trace amounts of a hazardous chemical (as determined under paragraph (d) of this section), and does not pose a physical hazard or health risk to employees." Paragraph (b)(6)(v) excludes articles from the section. Nothing on these pages determines whether any item is an article, because that turns on a particular use.
