The Six-Stage Cooperation Process at a Glance

The whole process is designed so that no money changes hands for bulk production before the design, materials, and sample are approved. Each stage produces a document or physical item that becomes the reference for the next stage: the requirement brief, the quotation, the approved sample, the production plan, the inspection report, and the packing list.

The durations are typical ranges for custom down jackets and puffer jackets. They change with design complexity, material availability, season, and order quantity. What does not change is the order of the stages, because each one depends on the confirmation produced by the previous one.

For a first-time buyer, the most important thing to understand is that the cooperation process is a sequence of small, reversible commitments followed by one large, irreversible commitment. Sampling is the small commitment that validates the design; the deposit and bulk production are the large commitment that follows written approval.

Stage 1: Consultation and Requirement Confirmation

The cooperation process starts with a consultation, usually by email or video call. The purpose is not to get a price on the first call; it is to define the project well enough that the quotation you receive later is meaningful. Ginwen asks about the brand stage, the target market, the product type, and the expected launch date, because these four factors drive most of the decisions that follow.

• Brand stage: launch, market test, or scale-up, which affects MOQ expectations and payment flexibility
• Target market: US, EU, or other regions, which affects sizing, labeling, and compliance requirements
• Product scope: styles, colorways, sizes, and whether the first order is a pilot or a full program
• Launch date: the retail or e-commerce launch date, which drives the production calendar
• Cooperation mode: OEM based on your design, or private label with Ginwen's in-house design support

During this stage the factory also confirms the cooperation mode. In an OEM project, you provide the design, tech pack, or reference sample, and the factory executes production. In a private label or full-package project, Ginwen can handle design development, pattern making, material sourcing, production, and packaging under your brand name. Many first-time buyers start with a reference sample and let the factory translate it into a production-ready specification.

By the end of the consultation, both sides should have a written requirement brief covering the product, the quantity, the timeline, and the budget direction. The brief does not need to be perfect, but it needs to exist, because every later stage is checked against it.

Stage 2: Design, Material Sourcing, and Quotation

Once the requirement brief is confirmed, the factory develops a production plan and a quotation. For a down jacket, the quotation is built from identifiable components: shell fabric, lining, down fill, zippers and hardware, trims, labels, labor, and packing. An itemized quote lets you see exactly what you are paying for and makes it possible to adjust the specification to hit a target price.

The quotation states what is excluded as well as what is included. Freight, duties, and third-party inspection fees are normally quoted separately, because they depend on your destination and your chosen forwarder. The standard factory price is ex-factory or FOB, meaning all production costs are included but shipping is not.

This is also the stage to confirm the MOQ. Ginwen's standard minimum is 50 pieces per style. Pilot quantities below 50 can be discussed case by case when the design is simple, materials are in stock, and there is a clear path to repeat orders. The quotation should state the MOQ, the unit price at that MOQ, the sample fee, and the lead time in writing.

Do not skip the question of what happens if the specification changes after the quote. A written rule that changes are quoted before production begins protects both sides and prevents cost disputes later in the process.

Stage 3: Sampling and Approval

Sampling is the stage where the design becomes a physical jacket. Ginwen develops the pattern in-house, sources the materials, sews a development sample, and sends it for your review. A typical sampling round takes 7–14 days, depending on complexity and whether materials need to be sourced or are already in stock.

1. Submit your tech pack, sketch, or reference sample, plus target fabric, fill power, sizing, and branding notes
2. The factory reviews the brief, develops the pattern, and confirms material direction with you
3. The development sample is sewn and sent for fit and detail evaluation
4. You review measurements, stitching, zippers, fill, and branding, and request revisions
5. The revised sample is approved in writing, and it becomes the production benchmark

Sample fees range from $50 to $200 per development round depending on complexity, and the fee is deductible from the first bulk order. This means the sample stage is not a separate cost for a brand that proceeds to bulk; it is a prepayment that is credited back. Confirm this deduction in writing, because it directly affects the real cost of validation.

Never skip the pre-production (PP) sample on a first order. The PP sample is produced with the same materials and on the same production line as bulk, so it is the last true preview before your deposit goes into production. Written approval of the PP sample locks the specification that the bulk order must follow.

Stage 4: Bulk Production and Payment

Bulk production starts only after the sample is approved in writing. The factory procures the bulk materials, inspects them on arrival, and then runs cutting, sewing, filling, and assembly on the production line. Bulk production for custom down jackets typically takes 25–40 days, depending on quantity, style complexity, and season.

Payment terms are 30% deposit before production starts and 70% balance before shipment. The deposit funds materials and reserves production capacity; the balance is paid against the packing list before the goods leave the factory. This structure is standard in apparel manufacturing and applies to startup orders as well as established brands.

During production, the factory shares milestone updates, including photos of cutting, sewing, and filling. You should agree in advance on the update cadence, so you know what to expect and when. For most programs, a weekly update plus photos at key milestones is the practical minimum.

If a specification change is requested after production starts, it is evaluated for cost and schedule impact before it is accepted. This is why the sample approval is so important: the more precisely the sample is approved, the fewer changes are needed during bulk, and the more predictable the schedule becomes.

Stage 5: Quality Inspection

Quality control runs through the whole production stage, not just at the end. Incoming materials are checked when they arrive, in-line checks happen during cutting, sewing, and filling, and a final inspection is performed before packing. For down jackets specifically, the factory verifies fill power and fill weight rather than trusting supplier claims, because fill is the most expensive material in the garment.

• Incoming QC: fabric weight, tear strength, down fill power, trims and zippers
• In-process QC: baffle and seam construction, fill weight per garment, stitch quality
• Final inspection: AQL 2.5 sampling for visual defects, measurement verification, zipper function
• Pre-shipment check: random batch inspection and packing review
• Documentation: inspection reports and photos shared before shipment

AQL 2.5 is the common industry standard for acceptable quality level in apparel. If you want an independent check, third-party inspection by SGS, Bureau Veritas, or Intertek can be arranged at your request and cost. The factory's quality management is covered by ISO 9001, and the production environment follows BSCI social compliance standards.

Agree in advance on how defects found at final inspection are handled: rework at the factory's cost, replacement pieces, or a price adjustment. Written rules for this scenario protect both sides and keep one bad batch from derailing the whole cooperation.

Stage 6: Packing and Shipment

The final stage is packing and shipment. Standard export packing includes polybags, cartons, and the shipping marks you specify, with neck labels, size labels, care labels, and hangtags applied during production. The factory prepares the packing list, and the 70% balance is paid against it before the goods are released.

Freight is arranged either by the buyer or by the factory on the buyer's behalf, depending on the trade terms agreed in the quotation. Sea freight from southern China to the US or EU typically takes 3–5 weeks; air freight is faster but substantially more expensive. For seasonal programs, plan the whole calendar backward from the launch date, adding buffer for sample revisions and freight variability.

1. Confirm the packing standard: polybag, carton quantity, and shipping marks
2. Receive the packing list and pay the 70% balance
3. Book freight with your forwarder or through the factory
4. Track the shipment and receive the bill of lading and export documents
5. Receive the goods and check them against the packing list on arrival

The shipment stage closes the first order, but it also opens the next one. Brands that run a clean first program typically reorder with a shorter process, because the pattern, materials, and quality standard are already established. Reorders can often skip the development sample and go straight to production with a PP sample check.

What to Prepare Before Your First Inquiry

The speed and quality of the whole cooperation process depend heavily on the information provided in the first inquiry. A complete brief lets the factory quote accurately and identify risks early; a vague brief produces a generic response and a longer clarification loop.

• Product details: style type, silhouette, target fabric, fill power, and features
• Quantity plan: number of styles, colorways, sizes, and expected order volume
• Design assets: tech pack, sketches, reference photos, or a physical sample
• Branding requirements: logo application, labels, hangtags, and packaging
• Market and compliance: target region, sizing, and any certification requirements
• Timeline: launch date and any hard deadlines, so capacity can be checked
• Budget direction: target price range, so the specification can be adjusted

Brands that send a complete brief receive a structured proposal with a clear MOQ, unit price, sample fee, and lead time, which shortens the whole process by days. The brief does not need to be professionally formatted, but it should be complete enough that the factory does not have to guess.

If you do not have a tech pack, say so explicitly. Ginwen offers in-house design support that translates reference images, sketches, or descriptions into production-ready patterns and specifications, so a missing tech pack does not block the process.

Common Mistakes to Avoid in the Cooperation Process

Most delays in custom jacket projects come from a small set of repeatable mistakes. Knowing them in advance helps you avoid the most common causes of missed launch dates.

1. Skipping written sample approval: verbal approval is not a production instruction, and it creates disputes about the specification later
2. Changing materials after the quote: a fabric or zipper change after quotation affects price and schedule, so decide materials before the sample is approved
3. Not confirming the sample fee deduction: the $50–$200 sample fee is deductible from the first bulk order only if the terms are confirmed in writing
4. Starting too late for the season: planning the calendar backward from the launch date avoids air-freight bills and missed retail windows
5. Withholding market information: the target market drives sizing, labeling, and compliance, so sharing it early produces a more accurate quote
6. Ordering multiple untested styles at once: testing one style through the full process is cheaper than discovering a fit problem across five styles

The pattern behind these mistakes is the same: skipping a checkpoint to save time, and then paying for it later. The cooperation process exists precisely to catch problems at the stage where they are cheapest to fix, which is why each stage ends with a written confirmation.

If you are not sure where to start, send the factory a description of your project and your launch date, and ask which information is missing. A professional manufacturer will tell you exactly what it needs rather than guessing.
