Apparel Production Process: From Tech Pack to Bulk Shipment

The Three Stages of Garment Manufacturing

The apparel production process is not a single event but a carefully orchestrated sequence of operations. It is generally divided into three major stages: Pre-Production (planning, sourcing, and sampling), Production (cutting, sewing, and assembly), and Post-Production (finishing, inspection, packing, and shipment).

Knowing what happens at each stage—and what you, as the buyer, are required to provide—can drastically reduce delays, eliminate miscommunications, and ensure that your final product meets your quality expectations.

Stage	Buyer Input	Factory Output	Common Delays
Pre-Production Spec review, sampling, material sourcing	Tech pack, reference samples, size chart, fabric preference	Quote, fabric swatches, Proto sample, Fit sample, PP sample	Indecision on fabric, unclear fit feedback, missing trim approvals
Production Cutting, sewing, inline QC	Final approval of PP sample, bulk deposit payment	Cut panels, sewn garments, inline inspection reports	Late approval of PP sample, sudden changes to grading rules after cutting
Post-Production Finishing, AQL inspection, packing	Balance payment, freight forwarder details, packing requirements	Cleaned, pressed, packed cartons ready for dispatch	Delayed balance payment, lack of clear shipping instructions

Pre-Production: Planning and Sourcing

Inquiry and Spec Review

The process begins when you submit an inquiry. To provide an accurate quote, a factory needs a comprehensive Tech Pack. This document should include flat sketches, a Bill of Materials (BOM), specific construction details, and a size chart with grading rules. If you do not have a formal tech pack, clear reference images combined with a physical reference sample and target size chart are acceptable starting points. We also need to know your target fabric requests.

Quote and MOQ Logic

Once we review your inputs, we provide a quotation. Cost and Minimum Order Quantities (MOQ) are heavily intertwined. A factory's MOQ is usually driven by the fabric mill's MOQ. If you choose an in-stock fabric from the Guangzhou market, the MOQ can be as low as 100 pieces per style. If you require custom dyeing, specific fabric weights, or custom prints, the MOQ will naturally increase. Other factors that affect cost include the number of colorways, the size range (inclusive sizing requires more fabric per unit and complex grading), construction complexity, and custom trims or packaging.

Fabric and Trim Sourcing & Testing

Before bulk production begins, all materials must be finalized. We source fabric swatches or produce lab dips for custom colors for your approval. We also rigorously test materials for fabric weight (GSM), shrinkage after washing, colorfastness, and potential color variation across different dye lots. Trims like custom zippers, buttons, and woven labels must also be approved at this stage.

Sample Development

Sampling is a multi-step process:

• Proto Sample: The first draft to review the basic design and silhouette.
• Fit Sample: Made in the correct fabric to evaluate how the material drapes and stretches on a fit model.
• Size Set: Samples in extreme sizes (e.g., XS and XXL) to verify the grading rules.
• PP Sample (Pre-Production Sample): The final, sealed sample made with bulk fabric and trims. This is the absolute standard for bulk production.

Production: Cutting and Sewing

Production Planning

After the PP sample is approved, we hold a pre-production meeting with the cutting and sewing teams. We create detailed operation sheets and execute line planning to optimize the workflow and prevent bottlenecks.

Cutting and Bundling

Before cutting, fabric rolls must be relaxed to prevent garments from shrinking after assembly. We use CAD software to create a highly efficient "marker" (the layout of pattern pieces on the fabric) to minimize waste. Once cut, the fabric panels are carefully bundled and numbered to ensure that parts from different dye lots or sizes are not mixed during sewing.

Sewing and Inline Inspection

The bundles move to the sewing lines. Here, garments are assembled step-by-step. During this phase, inline inspection is critical. QC personnel patrol the lines hourly, checking stitch density, seam strength, and crucial measurements. If an operator is consistently making an error, it is caught immediately, allowing for immediate rework before the entire batch is flawed.

Post-Production: Finishing and Logistics

Finishing, Final Inspection, and AQL Sampling

Once sewn, garments are trimmed of loose threads, ironed or steamed, and sent for final inspection. Mostnica operates under the internationally recognized AQL 2.5 (Acceptable Quality Limit) standard for major defects. This statistical sampling method ensures a high, consistent standard of quality across the entire order. We also welcome third-party inspection agencies.

Quality Gate Checklist
Fabric Gate	Check for color shading, fabric flaws, correct weight (GSM), and shrinkage testing results.
Cutting Gate	Verify marker accuracy, check panel dimensions against patterns, ensure proper bundle ticketing.
Sewing Gate (Inline)	Check stitch tension, seam puckering, alignment of pockets/collars, and adherence to the PP sample.
Finishing Gate	Verify thread trimming, pressing quality, label placement, and overall garment cleanliness.
Packing Gate	Check barcode accuracy, verify polybag warnings, confirm folding methods, and ensure correct carton assortments.

EXW, FOB, and the Logistics Boundary

After packing, the goods are ready for dispatch. It is vital to understand shipping terms. EXW (Ex Works) means the buyer takes responsibility the moment the goods leave our factory floor. FOB (Free On Board) means we cover the costs and risks to transport the goods to the nearest port (e.g., Shenzhen or Guangzhou) and load them onto the vessel. For international shipping, DDP, and navigating destination-side customs, we strongly recommend that buyers partner with an experienced freight forwarder.

The Mostnica Fit

At Mostnica, our expertise lies in fast-response womenswear and everyday apparel. Located in Panyu, Guangzhou, we leverage the vast Zhongda fabric market ecosystem to offer agile production. Whether you need a 100-piece trial order to test a new style or a 50,000-piece bulk run, our facility operates strictly under AQL 2.5 standards, ensuring that speed never compromises quality.
