What every comparable factory quote must include
Same specification line
Ask each plant to repeat capacity, neck finish, glass color, lid type and decoration process on one line. If a plant substitutes 1 oz for 2 oz or changes a 53-400 continuous thread to a 58-400, treat that as a new construction, not a silent equivalent. A 2 oz sample jar and a 1 L pantry jar cannot share that line even when both are flint.
Costs outside the piece price
Mould or neck-ring tooling, print plates or screens, lid machining, 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 blank, a decorated sample or a line-trial quantity. Request food-contact and migration testing files for the named glass, closure 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 screen 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. A die line for a wrap label should travel with the jar drawing so print buyers can quote colors on the same silhouette.
Small-capacity 2 oz programs change pack-out more than they change glass chemistry. Partition cell count, paperboard caliper of the inner carton and edge crush test of the shipper belong on the RFQ because breakage risk scales with more pieces per layer. 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.
