# How to Add Required Product Fields for TikTok Shop


## Overview

TikTok Shop, has its **own requirements** for uploading products and listing them for customers. 
Currently, TikTok Shop **requires every product to include**:
* **Weight**    
* **Length**    
* **Width**    
* **Height**

These requirements help guarantee a **better customer experience**. Additionally:

* **Size chart** is required for **clothing products**    
* **Product certification files** are required for **certain categories** like electronics

If these required fields are missing, the product **cannot be synced** automatically to your TikTok Shop store. (For example, uploading manually in TikTok Seller Center without required fields would also prevent product submission.)
## 1. Add Required Fields via Product Syncing Dashboard

In **Product Syncing**, you select which products to sync to TikTok Shop. The app will **automatically detect missing required fields** before allowing sync.

### Steps:

1. Go to **Product > shopify product ** in TikTok Shop Connector by SPL.

If your product is **exempt from barcodes**, you can leave it empty. However, adding barcodes is recommended for a **better product health score** on TikTok Shop.

## Why Are Required Fields Important?

TikTok Shop uses **product dimensions and weight** to:

* Accurately calculate **shipping fees**
