The DJI Mini 4K, a new budget-friendly drone with a 4K camera weighing just 249 grams, leaves many people wondering whether it must be registered under Thai law.
Many people believe "drones weighing under 249 grams don't need to be registered" because the laws of many countries use a weight-based exemption, but Thai law uses the "camera" as the criterion — once there is a camera, registration is required immediately, no matter how light the aircraft is.

Does it require NBTC registration?
Answer: Yes, NBTC registration is required. Because Thai law clearly states that "every drone model with a camera must be registered," regardless of weight.
NBTC registration is the application for permission to use the drone's radio frequencies, which is required by law. Apply online at anyregis.nbtc.go.th, select the คท.30 form, fill in the brand, model and Serial Number (usually located under the battery or on the box), and upload a copy of your ID card, a full photo of the drone, photos of the Serial Number on the aircraft and the remote controller, and the receipt (each file no larger than 1 MB).Within 30 days from the purchase date
Once approved, pay the government fee of 214 baht (VAT included), then download the คท.30 certificate and keep it on your phone to show officers when you fly. The certificate is valid for the lifetime of that drone.

Do I also need a CAAT license?
Personal use: NBTC only required | Both NBTC + CAAT requiredCommercial use / foreigners:
"Commercial" as defined by CAAT covers flying for hire, generating income, or supporting a business — such as real estate photography, advertising, weddings or events. In this case you must obtain a pilot license and register the aircraft through uasportal.caat.or.th, attaching a third-party insurance policy of no less than 1,000,000 THB per incident. Document review takes approximately 15–20 business days. Foreigners must also complete registration with both agencies.

Common misconceptions among Mini 4K users
- "249 grams = exempt": Thai law exempts only toy drones that "have no camera and weigh no more than 2 kilograms" — the Mini 4K has a camera, so it does not qualify for the exemption.
- Fly first, register later: The law does not allow flying without registration even for a single day.
- Bought second-hand and still flying under the previous owner's name: You must always transfer ownership and arrange insurance in the new buyer's name before flying.
- Blurry Serial Number photo: Rejected documents waste time re-filing. Use adequate light and macro mode, and check that every character is readable before submitting.

Frequently Asked Questions (FAQ)
The DJI Mini 4K weighs only 249 g — does it really need to be registered?

Using a Mini 4K to shoot photos for a sales page — is NBTC registration alone enough?
Not enough. If the flying generates income or supports a business, it counts as commercial: you must register with the CAAT and carry third-party insurance of no less than 1,000,000 THB (5–10 million THB recommended for commercial use), and check the no-fly zones before every flight.
How severe is the penalty for not registering the Mini 4K?
