Three are price misreadings. Two are match misreadings.
Reading the case price as a case total
It is a per-unit price that applies when a full case is bought. Treated as a case total it would imply a jar costs a fraction of a cent, which is the sort of error that survives a long way into a spreadsheet.
Pricing a container without its closure
A jar without a lid holds nothing. The complete unit at single prices runs 42 to 803 cents with a median of 108, against a container median of 90.5 on its own.
Budgeting on single prices for an order that will be a full case
The median discount is 28 percent and the median container case is 288. Most orders on this shelf will see the case price, so the single price is the wrong figure to plan against.
Treating thirty six unmatched containers as thirty six gaps
Nineteen of them record no neck finish at all, so the match fails on an empty field. The genuine count is seventeen containers with a recorded finish and no closure listed here.
Treating a shared neck finish as a tested fit
Two rows sharing a nominal finish are recorded as compatible in the catalog. That is a record, not a test, and no page in this library claims any specific pair has been fitted together.
Expecting a container record to carry a production identity
There is a catalog number and a supplier reference and nothing else. No lot, no batch, no date, no certification reference. Five properties in this library now report the same absence independently.
Reading a price as current
Every figure here is a snapshot of 19 October 2026. A price is not a durable property of a container, and 93 of the 251 containers are quote only and carry no published price in the ordinary way at all.
And reading part 770 as a rule about any of this
It sets formaldehyde emission standards for composite wood products at 0.05 to 0.13 parts per million by product class. It is the spine of this property because it is the only rule in this library that attaches to an ingredient and follows it into a finished good, not because it reaches a hinge or a shelf pin.

The Davis Pack Supply catalog, measured 19 October 2026, and a snapshot of that day rather than a current price. Single-unit prices: 250 containers from 21 to 705 cents with a median of 90.5; 286 closures from 5 to 445 cents with a median of 39. The recorded case price is a per-unit price rather than a case total. The ratio of case-unit price to single price runs 0.667 to 0.887 for containers with a median of 0.720, and 0.625 to 0.929 for closures with a median of 0.722, so a median discount of 28 percent in a band of roughly 11 to 37. Not one row of 536 has a case-unit price at or above its single price; 7 of 250 containers and 45 of 286 closures beat a 30 percent discount, and nothing on the shelf reaches 40. Case-unit prices run 14 to 507 cents for containers, median 66, and 4 to 320 for closures, median 29.
The Davis Pack Supply catalog, measured 19 October 2026. 215 of the 251 containers on this shelf share a nominal neck finish with at least one closure on the same shelf, which is a catalog match and not a test of fit. 36 do not, and 19 of those record no neck finish at all, so 17 containers carry a recorded finish for which no closure here is listed. The number of matching closures per container runs from 1 to 66 with a median of 61. Taking each container with its cheapest matching closure at single-unit prices, a complete unit runs 42 to 803 cents with a median of 108, and the closure accounts for 2.8 to 48.1 percent of that with a median of 15.4 percent: 10 of 215 at 30 percent or more, 3 at 40 or more, and none above half. 93 of the 251 containers are quote only.
40 CFR 770.10. Paragraph (a): "Except as otherwise provided in this part, the emission standards in this section apply to composite wood products sold, supplied, offered for sale, or manufactured (including imported) on or after June 1, 2018 in the United States. These emission standards apply regardless of whether the composite wood product is in the form of a panel, a component part, or incorporated into a finished good." Paragraph (b), based on test method ASTM E1333-14: "(1) For hardwood plywood made with a veneer core or a composite core, 0.05 parts per million (ppm) of formaldehyde. (2) For medium-density fiberboard, 0.11 ppm of formaldehyde. (3) For thin medium-density fiberboard, 0.13 ppm of formaldehyde. (4) For particleboard, 0.09 ppm of formaldehyde."
