A tech pack is the backbone of apparel production. When it is complete, production moves seamlessly; when details are missing, delays and incorrect samples quickly erode your margins. Many brands, especially startups, underestimate how small omissions in documentation can derail an entire collection. This guide breaks down the most commonly forgotten garment details and explains how to close these gaps to ensure factory-ready accuracy.

Why Incomplete Tech Packs Are a Business Risk

An incomplete tech pack is more than an inconvenience—it is a financial risk. Professional factories operate on a “no guessing” rule. If a detail is missing, the assembly line stops. Each pause costs time, potentially missing seasonal launch windows. A thorough document protects your timeline and allows the Mekong Garment team to work continuously toward your deadline.

6 Details Often Missing from Tech Packs

1. Specific Stitch Types and SPI

Simply writing “sew seam” is insufficient. Factories need to know the exact Stitch Type (e.g., Lockstitch, Overlock, Flatlock) and the SPI (Stitches Per Inch). SPI directly affects garment strength and aesthetic; higher SPI looks premium but takes longer to sew. Without this, the factory will default to their standard, which may not match your brand’s durability goals.

2. Seam Allowance and Seam Finishes

If not specified, factories will use their default seam allowance (usually 1 cm). This becomes a major issue if the garment needs future alterations or a specific high-end finish like Flat-felled seams or French seams. The internal finish defines the comfort and “luxury feel” of the garment from the inside out.

3. Comprehensive Fabric Descriptions

Fiber content (e.g., “100% Cotton”) is only the beginning. A production-ready tech pack must include:

  • Weight: GSM or OZ ranges.
  • Construction: Jersey, Rib, Interlock, or Twill.
  • Finish: Enzyme-treated, brushed, or silicon-washed.
  • Performance: Target shrinkage % and colorfastness grades.

4. Trim and Hardware Definitions

Every button, zipper, and label must be fully defined by: Material, Size, Finish (e.g., Matte Black vs. Shiny Brass), and exact placement. Care labels are frequently forgotten, yet they are a legal requirement in most global markets.

5. Precise Packaging Instructions

How a garment is folded and bagged affects its arrival quality. Specify polybag thickness, hangtag placement (which seam?), and carton markings. Skipping this step leads to wrinkled stock and potential rejections at fulfillment centers like Amazon FBA.

6. Quality Standards (AQL) and Compliance

Quality is not subjective. Your tech pack should state the Acceptable Quality Limit (AQL 2.5/4.0), major vs. minor defect limits, and any required third-party certifications. Defining these upfront prevents disputes during the final inspection.

Conclusion

A well-prepared tech pack is a production strategy, not just paperwork. Every line you add reduces a potential risk; every detail you define saves a dollar in rework. By investing effort into these often-missed details, you ensure a smoother sampling process and a final product that truly reflects your brand’s vision. At Mekong Garment, we help you refine these technical points to guarantee world-class results from the very first sample.
