How to Send a Tech Pack to Your Clothing Manufacturer?

🧠 What Is a Tech Pack (And Why It Matters)?

A tech pack (technical package) is a detailed document that explains how your garment should be made. It includes specs, sketches, materials, sizing, trims, and more.

From a manufacturer’s perspective, it’s your blueprint. Without one, they’re left to guess—and that leads to errors, delays, and misaligned expectations.

📢 Buyer quote: “We sent reference photos, but the hoodie sample came back completely wrong. Now we know why factories insist on a tech pack.”

📄 Core Components of a Professional Tech Pack

A complete tech pack should include the following:

1. Cover Page with Style Info

Start with your brand name, style code, product name, and target season. Include a clear image of the product (line art or reference photo).

2. Technical Flats or Sketches

Show front and back views of the garment. These drawings should be detailed but easy to interpret by a pattern maker. Use arrows, labels, and color markers.

3. Measurement Specs & Size Chart

List key measurements for each size (S, M, L, etc.) with tolerances. Use a consistent measurement unit (inches/cm) and highlight points of measurement (POMs).

4. BOM (Bill of Materials)

Break down all materials needed:

Main fabric (weight, composition)
Lining
Zippers, buttons, cords
Labels, hangtags, patches

5. Labeling & Branding Details

Include artwork for woven labels, neck prints, care tags, and brand logos. Clarify placements with images or layout guides.

6. Construction & Stitching Notes

Explain how parts are assembled: seam types, hem finishes, topstitching, etc. Factories will refer to this during pattern cutting and sewing.

💻 File Format, Versioning & Best Practices

Format	Use Case	Pros	Cons
PDF	Final files	Easy to print, secure	Not editable
Excel	Measurements / BOM	Editable, structured	Less visual
Cloud tools	Collaborating	Version control	Requires setup

✅ Best Practice:

Name files clearly: Hoodie_V1_2025_Q1.pdf
Keep a changelog: V1 = initial sample, V2 = feedback revisions, etc.
Avoid sending 10+ image attachments—use one compiled doc whenever possible.

📤 How to Submit Your Tech Pack to the Factory

There’s no single correct way—but the goal is clarity and confirmation.

✅ Email your factory contact with the full tech pack attached

✅ Include a short message: order quantity, target lead time, questions

✅ Follow up with WhatsApp if needed (but keep approvals in writing)

✅ Confirm receipt and agreement on specs before sampling starts

❌ Common Mistakes to Avoid (and How to Fix Them)

Mistake Problem: It Causes a Better Approach

Only sending photos	Leads to guessing/spec errors	Use structured drawings + specs
Missing BOM or trims	Incomplete cost quotes or wrong materials	Always include the BOM page
Feedback is scattered in the email	Hard to track changes	Annotate PDF + use versioning
