What Documents Do You Need to Start Clothing Production?

To start clothing production, you need a complete set of documents that define your product, materials, and order details.

At minimum, most manufacturers require a tech pack, size chart, fabric information, artwork files, and order details before sampling or production can begin.

Before working with a custom clothing manufacturer, preparing these documents helps reduce errors, speed up sampling, and ensure accurate production.

Quick Checklist: Documents Needed Before Clothing Production

This is the complete list of documents typically required:

Document	Required	Why It Matters	When to Prepare
Tech Pack	Required	Defines product specs	Before sampling
Size Chart	Required	Ensures fit accuracy	Before sampling
Fabric & Trim Info	Required	Controls materials	Before sampling
Artwork Files	Required	Ensures correct printing	Before sampling
Label & Packaging	Important	Branding consistency	Before bulk
Sample Approval Notes	Important	Final confirmation	Before bulk
Purchase Order	Required	Confirms order details	Before production
Shipping Info	Required	Ensures delivery	Before production

Tech Pack (Technical Specification Sheet)

The tech pack is the most important document in clothing production.

It tells the factory exactly what to make.

A complete tech pack includes:

Technical sketches (front and back)
Measurements and specifications
Fabric and trim details
Construction notes
Artwork placement
Label and packaging instructions
Measurement tolerance

Without a clear tech pack, factories must make assumptions, which often leads to errors and delays.

Size Chart and Measurement Tolerance

A size chart ensures your product fits correctly across all sizes.

It should define:

Base size
Grading rules
Measurement points
Tolerance range

Tolerance is critical because small measurement differences are normal in production.

Without it, even correct garments may be rejected or misunderstood.

Fabric and Trim Information

Fabric and trims determine product quality, cost, and production feasibility.

You should specify:

Fabric composition
GSM (fabric weight)
Color and dye method
Fabric finish
Trims (zipper, buttons, drawcord, elastic)
Lab dip or color approval

Providing clear fabric details helps avoid sourcing errors and delays.

When working with a custom clothing manufacturer, fabric clarity is essential for accurate sampling.

Artwork, Logo and Print Files

Artwork files control how your design appears on the final product.

You should provide:

Vector files (AI, PDF, SVG)
Logo placement
Print size
Embroidery position
Color reference

Low-resolution images or unclear placement instructions are one of the most common production issues.

Label and Packaging Details

Label and packaging details define your brand presentation.

This includes:

Main label
Care label
Hang tag
Poly bag
Carton mark
Barcode (if required)

These details are often confirmed after sampling but before bulk production.

Purchase Order and Quantity Details

The purchase order confirms your production requirements.

It should include:

Style number
Color options
Size breakdown
Total quantity
Unit price
Delivery date
Shipping address

This document ensures both you and the factory are aligned before production starts.

Sample Approval Notes

After receiving samples, you should document all feedback before bulk production.

This includes:

Fit adjustments
Fabric confirmation
Color approval
Print or embroidery changes
Packaging confirmation

Clear approval notes prevent repeated mistakes during bulk production.

If you need help refining samples, working with teams that offer sample development support can improve accuracy before final production.

Required vs Optional Documents

Not all documents are required at the same stage.

Here is a simplified breakdown:

Required Documents

Tech Pack
Size Chart
Fabric Details
Artwork Files
Quantity Breakdown

Optional but Useful

Brand Guide
Packaging Guide
Reference Samples
Color Cards
Testing Requirements

Understanding this helps you start production even if some details are not finalised.

Common Mistakes When Sending Production Documents

Many production issues come from incomplete or incorrect documents.

Common mistakes include:

Sending low-resolution artwork
Missing measurement tolerance
Unclear fabric details
Changing specifications after sample approval
Not confirming packaging before bulk production

Avoiding these issues can save both time and cost.
