OEM Hijab Development Calendar and Factory Handoff: Tech Packs, Sample Revisions, Approvals, MOQ, Capacity Booking, and Delivery Risk Control

Why the Development Calendar Decides Whether an OEM Hijab Program Ships

For an emerging DTC brand, a boutique adding its own label, or a private-label buyer building a hijab range, the distance between a good idea and a container-ready order is not creativity. It is development discipline. Every OEM hijab program moves through the same sequence of gates: tech pack, first sample, sample revisions, approval sign-off, MOQ commitment, capacity booking, bulk production, inspection, and delivery. Sequenced correctly, the program is predictable and financeable. Compressed or run out of order, cost and risk compound quietly until the delivery date becomes impossible and the only remaining lever is expensive air freight.

Most first-time buyers lose time in three predictable places: an incomplete tech pack that forces the factory to guess, an open-ended revision loop with no agreed revision limit, and a capacity booking that was never actually reserved because no deposit was paid. At QiuYan Factory we treat the development calendar as a shared, dated document owned by both the buyer and the factory. This guide walks that calendar gate by gate, with the technical and commercial parameters you can hold any OEM supplier to.

The OEM Development Calendar, Gate by Gate

Think of the calendar as ten gates. Each gate has an owner, a duration, and an output that must be signed before the next gate opens.

• Gate 0, brief and feasibility (2-4 business days): style, market, target price, quantity band, and delivery window. The factory confirms whether the brief is technically and commercially feasible.
• Gate 1, tech pack locked and quoted (3-5 business days): the buyer issues a complete tech pack, and the factory returns an itemized quotation covering fabric, cut-make-trim, trims, packing, and testing.
• Gate 2, first sample round (5-7 business days): the sampling room builds the first prototype in the specified fabric and color.
• Gate 3, sample revisions (5-7 business days per round, budget two rounds): fit, drape, hand-feel, and measurement corrections are made against the buyer's comments.
• Gate 4, lab dips and color approval (10-14 working days total): dyed swatches are measured instrumentally and a shade band is signed.
• Gate 5, pre-production (PP) sample sign-off (5-7 business days): the reference sample that bulk must match is sealed and retained by both parties.
• Gate 6, MOQ confirmation and capacity booking (deposit-triggered): the purchase order and deposit lock the production slot.
• Gate 7, bulk production (15-20 working days): cutting, sewing, finishing, and pressing.
• Gate 8, final inspection and packing: AQL 2.5 inspection and packing per the approved packing spec.
• Gate 9, dispatch and freight: documentation, booking, and shipment.

Run sequentially without overlap, a program from a clean tech pack to dispatch-ready goods sits in the 10-14 week range, before ocean transit. The mistake is treating these gates as a wish list rather than a schedule. Dated gates, with a named owner on each side, are what convert a calendar into a commitment.

The calendar is not a straight line, and two overlaps are legitimate. Color can run in parallel with construction sampling, because the dyehouse and the sampling room are independent, so a lab dip window and a first-sample window can share the same week. Fabric booking can begin once the tech pack is locked and the fabric is specified, even before the PP sample is signed, provided the buyer accepts the small risk of a specification change. Everything else should stay sequential, because approving a PP sample before the color is settled simply books a re-dye against your own delivery date.

A useful test for any calendar: every gate should end with a document. Gate 1 ends with a signed quotation. Gate 3 ends with comments on a specific round. Gate 4 ends with a signed shade band. Gate 5 ends with a sealed PP sample. Gate 6 ends with a purchase order and deposit receipt. If a gate ends only with a message saying it looks good, it has not really closed.

The Tech Pack: The Document That Sets Your Price and Your Date

A tech pack is the single document that determines whether a factory can quote accurately and sample quickly. When it is thin, the factory quotes a wide price band to protect itself, and sampling drifts into repeated clarification. A complete OEM hijab tech pack should contain:

• Style and silhouette: shape, length, width, edge finish (rolled hem, overlock, baby hem), and any layering or attachment points.
• Measurement spec: a full point-of-measure chart with a tolerance column. For hijab panels we work to plus or minus 0.5 cm on length and width and plus or minus 0.3 cm on trim placement, unless the buyer specifies tighter.
• Fabric specification: fiber content, exact GSM, construction, and finish. A shade approved on one substrate is not the same color on another, so the substrate must be declared.
• Color references: Pantone FHI TCX chips or physical swatches, plus the required color target and the acceptable color difference.
• Trims and labels: care labels, woven or printed branding, hangtags, and thread color.
• Packaging: polybag, header card, folding, and carton configuration.
• Size grading and assortment: how many colorways and sizes, and the split between them.
• Commercial fields: target quantity, delivery window, Incoterm, and destination.
• Compliance and labeling: the destination market's fiber-content and care-labeling requirements.

If a buyer cannot fill these fields, the honest next step is a paid development round, not a guessing game. A 3-5 business day quoting turnaround is realistic only against a complete pack.

Fabric, GSM, and Construction: Weaving and Knitting

Hijab fabric falls into two construction families, and the family you choose drives cost, drape, and how the article behaves after washing.

Woven constructions are built on a loom by interlacing warp and weft yarns. The modest-wear staples are chiffon (light, airy, slightly crisp), crepe (matte, fluid, forgiving of creasing), voile (soft and breathable), satin (lustrous and heavier-drape), and twill (structured). Knitted constructions are built by interlocking loops: single jersey, interlock, and rib, which give stretch and recovery that wovens cannot.

Practical GSM bands we run: chiffon 55-75 GSM, voile 60-85 GSM, crepe 90-120 GSM, single jersey 150-190 GSM, interlock 180-220 GSM, and heavy-weight knits above 220 GSM. Always specify a weight tolerance of plus or minus 5% and a usable-width tolerance of plus or minus 2%, because unchecked GSM drift changes drape, opacity, and the finished hand-feel. Also specify shrinkage: no more than 3% in either direction after the agreed wash cycle, tested on the production fabric, not a lab substitute.

For woven articles, state yarn count and density, for example a 50D by 75D warp and weft with a defined picks-per-inch. For knits, state the stitch and the fabric's stretch and recovery at a defined load. These are the numbers that make a fabric order reproducible rather than a lucky match.

Sample Revisions and Approval Gates

Sampling is not one event; it is a controlled loop with an explicit exit. The first sample proves the concept. The pre-production sample proves that the concept can be manufactured exactly, at the specified construction and color, and becomes the sealed reference for bulk.

Two rules keep the loop from running forever. First, cap the revisions: agree in the purchase order that the price includes two revision rounds, with additional rounds quoted separately at a stated fee. Second, approve against data, not impressions. Each round should be assessed on measurement against the point-of-measure chart, hand-feel and drape against the sealed reference, and color against an instrumental reading.

Color is where most revisions stall. We hold bulk color to Delta E at or below 1.0 as an internal target, at or below 1.5 as the normal commercial acceptance band, and at or below 2.0 only where cross-substrate matching cannot be tightened; any lot above 2.0 is rejected and re-dyed. Specify the equation in the purchase order, Delta E 2000 preferred, and read the DL*, Da*, and Db* components separately so you can see whether a lot is running light, red, or blue rather than merely how far off it is.

At the end of sampling, both parties sign the PP sample. From that moment, bulk quality is measured against a physical reference, and a final AQL 2.5 inspection at the factory confirms that what shipped matches what was approved. AQL 2.5 is the standard commercial sampling plan for major defects: it accepts a defined number of defectives and rejects the lot when the count exceeds the limit, which is exactly the discipline an OEM program needs before goods leave the floor.

The Handoff Package: What Must Move From Development to Bulk

The factory handoff is the moment development stops being a series of samples and becomes a production order. It fails most often because the buyer believes the file is complete and the factory believes it is not. A clean handoff package removes that argument. It contains the sealed PP sample, the approved shade band, the final measurement chart, the approved fabric and trim cards, the packing specification, and the labeled cartons from the last sample round. It also contains the commercial documents that make the order executable: the signed purchase order, the deposit receipt, the delivery window, and the Incoterm.

Two items are commonly missing. The first is the trim card for labeling, so bulk starts without the care labels that carry the destination market's required fiber and care information, and the line stalls while labels are reprinted. The second is the packing specification, so goods are finished but not packed to the buyer's carton plan and cannot be shipped without repacking. Both are inexpensive to lock at the handoff gate and expensive to fix during bulk.

We recommend a single handoff meeting, or a single handoff document, that lists every approved reference and every outstanding item with a named owner and a due date. When the factory can see, in one place, that the shading is signed, the labels are on order, and the packing spec is final, the 15-20 working day bulk clock starts cleanly instead of stalling on the first day.

MOQ and Capacity Booking

MOQ is not a single number. It is a ladder tied to fabric sourcing and dyeing, and understanding the ladder lets you plan colorways without surprise surcharges.

• Stock fabric, existing color: from 300 pieces per colorway.
• Stock fabric, custom dye: from 500 pieces per colorway.
• Custom-developed fabric: 1,000-1,500 pieces per colorway, because the mill runs a minimum greige batch.
• Printed programs: 500-1,000 pieces per design, depending on the print method and repeat.

Capacity, not price, is the real constraint in a peak season. A quotation is not a reservation. To actually book a production slot, you need a signed purchase order and a deposit, typically 30% of order value, which triggers fabric booking and line allocation; the balance is due against the shipping documents. During peak windows we recommend booking capacity six to eight weeks ahead of the required bulk start. Once booked, bulk runs 15-20 working days, but that clock only starts when the PP sample and shade band are approved and the fabric is in-house. A program that books capacity before its approvals are closed is buying a suit before it has been measured.

Delivery Risk Control

Every late hijab order traces back to one of six risks. Each has a control.

• Fabric delay: buy against a dated fabric-in-house milestone, keep a 10-15% buffer, and dual-source critical qualities.
• Dye re-dye: lock the shade band early, and budget the 10-14 working day color window rather than discovering it late.
• Revision loop: cap revisions and approve against measurement and Delta E.
• Capacity bump: reserve the slot with a deposit and confirm the line allocation in writing.
• Inspection failure: run AQL 2.5 before dispatch, not after arrival, so defects are fixed at the source.
• Freight and customs: match the Incoterm to your capability, build in clearance time, and hold an air-freight contingency for the top sellers only.

The single most effective control is a shared, dated gate calendar with the buffer stated openly. A supplier that will show you its line plan and its fabric commitments is a supplier you can plan around. A supplier that will not should be treated as a delivery risk regardless of price.
