What every comparable factory quote must include
Same specification line
Ask each plant to repeat capacity, glass color, stopper family and gasket compound on one line. If a plant substitutes a plastic stopper for ceramic, or a thinner wire for a heavier latch, treat that as a new construction, not a silent equivalent. Burst strength methods, when requested, belong to the corrugated shipper around the bottles rather than a marketing adjective on the glass wall. A 32 oz beverage bottle and a 250 ml oil bottle cannot share that line.
Costs outside the piece price
Moulds, change parts, wrap-label plates, 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 first-article bottle, a gasket lot letter or a line-trial quantity. Request food-contact and migration testing files for the named glass and gasket 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; a frozen long run often keeps unit cost and spot-color control better in flexographic printing. A die line for a wrap panel should travel with the bottle drawing so print buyers can quote colors on the same silhouette.
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.
