Step-by-Step Guide to Checking Pesticide Registration in Thailand (Updated 2025)

Previously, the Thai pesticide registration system required users to search by registration number through the Ministry of Agriculture’s database.

Now, there’s a faster and more direct way — you can download the entire official pesticide registration list with just a few clicks!

Let us walk you through the updated method.

Step 1: Visit the DOA’s Agricultural Regulatory Division Website

Go to the official DOA (Department of Agriculture) Agricultural Regulatory Division site:
👉 https://www.doa.go.th/ard/

You will enter the site as a guest. The homepage is in Thai.

📌 For easier navigation, you can use your browser’s auto-translate feature to view the page in English.

Step 2: Navigate to “STATISTICAL DATA”

Scroll the homepage and click on the section titled “STATISTICAL DATA” (or the Thai equivalent).

Then, select “Hazardous Substances Act”.

This section leads to pesticide data managed under Thailand’s hazardous substances regulatory framework.

Step 3: Access the Registration List

You will now reach the data table interface, where the latest pesticide registration list is available.

Here, you can:

• View the updated registration records
• Download the full list directly as an Excel or PDF file

This method is much more convenient than searching by registration number!
