How Long Does Sampling and Bulk Production Take?
Short, direct answer
For custom down jackets, sampling usually takes 7–14 days, and bulk production takes around 30 days after sample approval. At Ginwen, timelines are managed in-house with real-time production tracking to ensure on-time delivery.
Sampling Timeline for Custom Down Jackets
Standard Sampling Lead Time
Direct answer:
The standard sampling lead time for custom down jackets is 7–14 days.
This timeline applies to:
OEM custom designs
Private label branded samples
Fit samples, size samples, and pre-production samples
What Happens During the Sampling Stage?
Sampling is a critical step to validate design, fit, and quality before bulk production.
Sampling workflow:
Design & tech pack review
CAD pattern development & grading
Material confirmation (fabric, down filling, trims)
Cutting, sewing, and filling
Initial quality inspection
Sample delivery for approval
Because Ginwen has in-house CAD, cutting, sewing, and QC, we avoid delays caused by outsourcing.
Factors That May Affect Sampling Time
Sampling may take slightly longer if:
The design is highly complex
New fabrics or trims need sourcing
Multiple revisions are required
Special performance features are added (e.g. waterproof coating, bonded seams)
Even in these cases, we aim to keep sampling within 14 days.
Bulk Production Timeline for Custom Down Jackets
Standard Bulk Production Lead Time
Direct answer:
Bulk production for custom down jackets typically takes about 30 days after sample approval.
This timeline applies to:
OEM bulk orders
Private label bulk orders
Reorders of confirmed styles
Bulk Production Process (Step-by-Step)
Final sample approval
Material preparation & inspection
Bulk cutting & sewing
Down filling & construction
In-line quality checks
Final inspection
Packing & shipment preparation
Ginwen's monthly capacity of 500,000 pieces allows us to maintain stable timelines even during peak seasons.
What Can Affect Bulk Production Time?
Bulk lead time may vary depending on:
Order quantity
Fabric availability
Design complexity
Peak production seasons
Special packaging or labeling requirements
Our team provides real-time production updates so you always know the status of your order.
Why Ginwen Can Maintain Stable Lead Times
