The **License to Operate (LTO)** is a **mandatory regulatory authorization** required for any **local manufacturer, importer, or distributor of medicinal products operating in Thailand**. Issued by the **Thai Food and Drug Administration**, the LTO ensures that pharmaceutical activities within the country meet Thailand’s legal, safety, and quality standards.

Without a valid LTO, companies are **not permitted to manufacture, import, store, or distribute drugs in Thailand**, regardless of whether the product itself has been approved.

## Purpose of the LTO

The LTO is designed to ensure that organizations involved in the pharmaceutical supply chain:

- Operate from approved and compliant premises
- Follow Good Manufacturing Practice (GMP) or Good Distribution Practice (GDP) standards
- Maintain proper quality management systems
- Protect patient safety and product integrity

It is a **prerequisite** for drug registration and ongoing market authorization in Thailand.

## Who Needs an LTO?

An LTO is required for:

- **Local drug manufacturers**
- **Importers of finished pharmaceutical products**
- **Distributors and wholesalers**
- **Companies acting as local legal entities for foreign manufacturers**

Foreign companies typically rely on a **locally licensed partner** holding a valid LTO to conduct regulatory and commercial activities in Thailand.

### LTO Application & Compliance Requirements

To obtain an LTO, applicants must submit documentation related to:

- Company registration and legal status
- Facility layout and storage conditions
- GMP/GDP compliance evidence
- Quality systems and personnel qualifications

The Thai FDA may conduct **facility inspections** prior to approval. LTOs must be **maintained, renewed, and updated** to reflect any operational changes.
