Q: How long does zipper sampling take?
For stock colors and standard chain, samples are commonly ready in about 5 to 7 working days, excluding courier time. A custom dyed tape usually adds 7 to 10 days, because the laboratory must match the shade, run a pilot bath and confirm fastness before the sample is assembled. Custom sliders or new tooth profiles can add two to three weeks for tooling.
The clock should start when the specification is complete, not when the inquiry is sent. Missing information, such as a Pantone reference, a finished length, a tape width or a slider finish, is the most common reason a sample slips. Send a physical standard where possible, since a screen color and a dyed tape rarely agree.
Build the schedule backwards from the garment delivery date. Allow time for at least two sample rounds, one for concept and one for confirmation, plus shipping and internal approval. A sample that arrives two days before the production cut-off is effectively useless, so agree the sampling dates in writing at the same time as the bulk price.
