Q: What information do I need to provide for a zipper quote?
A usable inquiry covers chain type and size, tape and tooth material, finished length, color reference, slider type and finish, end type, and quantity per size and color. Add the application, because a zipper for a puffer jacket and one for a tote bag may share a size but need different tape, slider and strength.
Specify the standards you will inspect against: length tolerance, shade tolerance, pull strength, cycle life, and any compliance requirement such as OEKO-TEX, REACH SVHC or GRS. State the packing format, the label and any barcode requirement, because packing changes the unit cost and the carton dimensions.
Finally, give the commercial frame: target ship date, destination, incoterm and whether samples are required before the order. A quote without these is only a price, not a plan. If some details are still open, say so explicitly and ask for the options with their cost and lead-time impact, rather than accepting a single figure that may be based on assumptions you did not intend.
