What every comparable factory quote must include
Same specification line
Ask each plant to repeat capacity, lid diameter, resin, lid type and decoration process on one line. If a plant substitutes 16 oz for 8 oz or changes an 89 mm snap lid to a 110 mm tear-band lid, treat that as a new construction, not a silent equivalent. A deli sample tub and a 5 L industrial tub cannot share that line even when both are PP.
Costs outside the piece price
Mold or lid-ring tooling, in-mold label plates or screens, artwork revisions, inner partitions, pallets and freight stay outside the piece or carton price unless the reply lists them. A lower piece figure that hides tooling is not a cheaper total. This desk does not publish a savings percentage because the price comparison file on this site is empty.
Sample and document path
State whether you need a stock cavity, a decorated sample or a line-trial quantity. Request food-contact and migration testing files for the named resin, lid liner and ink pairing. Those documents belong to the supplier lot. They are not converted into a site-wide certification badge. Drawings follow after first contact; this form has no upload field.
Digital print versus flexographic printing or in-mold labels is a run-length trade-off, not a quality slogan. High SKU counts and frequent logo changes can reduce plate cost with digital print on a pressure-sensitive label; a frozen long run often keeps unit cost and spot-color control better in flexographic printing or IML. A die line for a wrap label should travel with the tub drawing so print buyers can quote colors on the same silhouette.
Small-capacity 8 oz / 250 ml programs change pack-out more than they change resin chemistry. Partition cell count, paperboard caliper of the inner carton and a 32 ECT or named burst-strength shipper belong on the RFQ because crush risk scales with more pieces per layer. Flexographic printing at four to six colors and an in-mold label film in the 80–140 μm range are different tooling lines. Write the rewind specification only if you also buy roll labels in the same brief; otherwise keep labels on a second line.
Limitations stay explicit: this desk does not promise US contract filling, does not hold inventory, and does not treat a supplier preference (high-end, mid-range, budget or undecided) as a verified rating. Read the RFQ checklist, then continue to inquiry options.
