In the garment industry, time is very important. If you miss a shipment date, it can cause big problems. The buyer may get angry. You may lose the order.

That’s why every apparel merchandiser uses a tool called the TNA Calendar.

Let’s understand what it is, why it’s important, and how you can use it easily.

What is a TNA calendar?

TNA means Time and Action.

A TNA calendar is a simple chart or schedule. It shows all the important tasks from order confirmation to shipment. It also shows when each task should be done.

So, it is like a to-do list with dates.

For example:

• When to book fabric
• When to get samples approved
• When to start production
• When to finish sewing
• When to ship the goods

It helps merchandisers stay on time and avoid mistakes.

Why is the TNA calendar important?

The garment business has many steps.

If one step is late, the whole order can be late. So, you must plan everything clearly.

A TNA Calendar helps you:

• Know what to do and when
• Remind others to do their work
• Track progress
• Catch delays early
• Deliver on time

For an apparel merchandiser, the TNA is like a daily guide.

Example of a TNA calendar

Let’s say the buyer gives an order on 1st January. The shipment date is 5th April. MOQ-30000 pcs. Here’s how the TNA may look:

Task	Deadline
Order Confirmed	Jan 1
Fabric Booking	Jan 4
Trims & Accessories Booking	Jan 4
Fit Sample Submission	Jan 31
Fit Sample Approval	February 10
Lab-Dip Submission	Jan 26
Lab-Dip Approval	February 2
PP Sample Submission	February 15
PP Sample Approval	February 25
Fabric In-House	March 2
Trims & Accessories In-House	March 5
Production Start	March 12
Final Inspection	April 1
Shipment	April 4

This way, you can check every step clearly.

What is the job of a merchandiser in TNA?

The merchandiser is the planner and controller.

He or she must:

• Make the TNA Calendar
• Talk with the factory, supplier, and buyer
• Follow up on every task

• Solve any problem quickly

A good merchandiser keeps everything on track.
