Why is drone-use permission required?

Many assume that spraying drones are merely agricultural tools, but in fact, their operation is governed by strict aviation laws similar to those for civilian aircraft. Operating without permission can lead to administrative fines of tens of millions of VND and pose risks to flight safety and the environment. Therefore, applying for permission to use crop-spraying drones is compulsory to ensure safety, legality, and regulatory compliance.

Risks of operating without authorization:

  • Fines from 20–40 million VND under Decree 162/2018 for violating flight regulations.
  • Drones may be confiscated or permanently banned if flown over restricted zones.
  • Complaints from residents due to low-altitude flights or chemical drift.
  • Ineligibility for insurance or compensation in case of accidents or malfunctions.

Practical benefits of obtaining permission:

  • Protects your legitimate rights in large-scale agricultural operations.
  • Enables collaboration with cooperatives and agri-businesses requiring legal documents.
  • Demonstrates professionalism, improving access to financing and insurance.

Anyone planning to use agricultural drones should complete the licensing process proactively to avoid penalties during random inspections or accidents.


What to prepare when applying for drone-use permission

The application dossier requires more than just a form; it includes several supporting documents, especially if the drone has long-range or wide-area capabilities. Proper preparation saves time and increases approval chances.

For modern agricultural drones like DJI Agras series, preparing accurate technical specifications is crucial, as the model, payload, and spraying system directly affect your permit review. Many applications are delayed because owners cannot provide complete documentation for imported DJI drones or fail to include the technical manual.

Documents required by the Operations Department – General Staff (Ministry of National Defense):

  • Application form for permission to use UAVs (official template).
  • Proof of drone ownership or lease/import contract.
  • Technical specifications (manufacturer, tank capacity, flight range, etc.).
  • Certificate of chemical safety.
  • Flight schedule and map indicating flight area and time.
  • Commitment not to fly over restricted or military zones.

Technical and legal requirements:

  • Drone must have a functioning, interference-free GPS system.
  • Spraying chemicals must meet safety standards, non-flammable, non-toxic.
  • Flight area must be at least 5 km away from airports, radar stations, or military zones.
  • The operator must be trained or certified, especially for large-scale operations.

If the drone is imported, include customs declarations and certificates of origin. Prepare both hard copies and scanned files for faster processing if additional submissions are requested online.


Step-by-step process for obtaining flight permission

Since the process involves coordination among agricultural, aviation, and defense authorities, follow these six steps to ensure approval without rejection or delay.

Step 1: Identify the drone type and flight zone

Specify your UAV’s model, control type, chemical capacity, and operating range. Define the spraying area clearly (commune, district, province, acreage, and schedule).

→ Avoid restricted areas near airports, radar stations, military bases, or defense factories.

Step 2: Prepare a complete application

Include 6–8 required documents:

  • Official application form
  • Technical specifications
  • Ownership/import documents
  • Flight map
  • Safety commitment
  • Pesticide documentation

→ Prepare scanned copies for online submission when needed.

Step 3: Submit to the Operations Department – General Staff

This is the only authority authorized to issue flight permits. Submit in person, by post, or via the official online portal.

→ Do not send applications to the Department of Agriculture or People’s Committee, as they lack authority.

Step 4: Track processing progress

After submission, you’ll receive a reference number. Processing takes 10–15 working days. Officials may inspect your equipment and request supplementary documents.

→ Stay in contact with the assigned officer to avoid delays.

Step 5: Receive approval and flight license

If approved, you’ll get an official document specifying validity period, authorized area, and conditions. This must be shown during inspections.

→ The document must bear the red seal of the General Staff and an official reference number. → Never copy another unit’s permit-this is a criminal offense.

Step 6: Operate according to the approved plan

Fly only within permitted zones and schedules. Assign a safety observer to monitor for chemical drift or unexpected risks.

→ Attach the permit number on the drone body for verification during field checks.


Common mistakes when applying

Even though the procedure is well-defined, many individuals and companies still make errors that lead to rejection or delays:

  • Vague flight area or time (“fields in Commune A”) without attached map.
  • Missing import/customs documents.
  • Incomplete technical specifications (flight altitude, tank size, battery type, safety features).
  • Unverified or unsafe pesticide usage.
  • Wrong submission agency (only the Ministry of National Defense can approve).
  • Flying before receiving the official permit.

Tip: Double-check your 8-item checklist and contact the Operations Department beforehand for clarification.


How to confirm your application was approved

You receive an official approval document

  • Title: “Approval for the use of unmanned aerial vehicles in agriculture.”
  • Includes reference number, signature, and red seal of the General Staff.
  • States permit holder, device type, flight time, and area.

Response within the standard timeframe

  • Normally 10–15 working days.
  • Supplement requests are sent formally via post or email.

No repeated correction requests

  • Approval on first submission indicates accurate documentation.
  • More than two correction rounds suggest checklist errors.

Permit verification during inspection

  • Inspectors will allow continued operation if your document matches the drone in use.

→ Flying before receiving the official permit is considered illegal even if pending approval.


Five ways to avoid penalties when operating spraying drones

Even with a valid permit, violations can still occur. Follow these five practices to remain compliant:

  1. Always carry the original permit: Inspections require the original document with red seal-not photocopies.
  2. Fly only within approved dates and zones: Operating outside the permitted window is deemed illegal.
  3. Label your drone with serial number and owner name: Helps trace responsibility in case of incidents.
  4. Use only approved chemicals: Any change in pesticide type must be reported in advance.
  5. Set up safety barriers and warning signs: Mark the area with “SPRAYING IN PROGRESS” signs and assign safety personnel.

Compliance during operation is as important as obtaining the license-it ensures legal safety and builds long-term credibility in agricultural drone services.


FAQs about crop-spraying drone permission

Is permission required if I spray only on my own farm?

Yes. Even for personal use, crop-spraying drones are classified as controlled flying devices under the Ministry of National Defense.

How long does it take to obtain permission?

Usually 10–15 working days for complete applications; longer if additional documents are needed.

Do imported drones require proof of origin?

Yes. Customs declarations or invoices must be included in the dossier.

Can I apply for multiple areas at once?

Yes, if you specify each zone and flight schedule. However, separate applications per phase are easier to manage.

What should I do if I lose the permit?

Submit a written request for re-issuance with loss confirmation. Do not operate until the replacement is issued.
