Requirements every comparable factory quote should include
Packhelp-style public quote pages show a brief-first path. That observation is a process reference from 2026-09-15, not this site's factory network or a lead-time promise.
Same construction assumption
Ask each plant to quote the same gallon or litre capacity, wall thickness in mil or mm, and lid pairing. A 5 gal / 18.9 L open-head and a 20 L tight-head are different jobs even when both search as plastic pail manufacturers. If one supplier answers IML and another answers a pressure sensitive adhesive wrap, keep those replies on two comparison rows.
Costs outside the piece price
Lid tooling, IML tools, plates, freight and document copies stay as their own lines. ISO ICS 55.020 supplies packing-unit vocabulary for quantity, not a certificate this service owns. A reply that only returns a unit number without those extras cannot be ranked against a reply that itemizes them.
Sample and decoration path
Write whether a physical sample pail is required before the production lot, and whether a later artwork change restarts plates. Digital short runs can reduce plate cost when SKU counts are high; conventional flexographic printing often keeps unit cost and spot-color control tighter on a stable long run. That trade-off is a buying choice, not a rating we assign to factories.
Limits we will not paper over
This service does not mould pails, store lid tools, or approve food-contact resins. Migration testing, if the fill requires it, is requested against a named resin and lid lot. We will not invent a savings percentage, a standing inventory figure, or an appointed-brand badge. If a destination needs pallet pattern or a UN 1H2 note, those notes belong in the same requirement box as quantity.
When the buyer still has an open die line or an undecided color count, the brief should say so. Factories can quote a range or decline. Forcing a fake complete spec to start a tender usually produces replies that cannot be lined up later. Read the RFQ checklist before opening inquiry options.
