What FAA regulations and restrictions do I need to know when importing agricultural drones to the US?

When our engineering team in Xi’an finalizes the calibration of a new heavy-lift sprayer, we know the hardware is ready, but the paperwork journey for our US clients is just beginning. You invest heavily in advanced agricultural Agricultural Aircraft Operator Certificate ¹ technology to boost crop yields, yet the fear crop yields ² of having your equipment seized by Customs or grounded by the FAA is a constant source of anxiety.

To import and operate agricultural drones in the US, you must navigate two main regulatory bodies: CBP for tariffs and the FAA for flight authority. You generally need an FAA Part 137 certificate for dispensing chemicals, a Section 44807 exemption for drones over 55 pounds, and mandatory Remote ID compliance for all units.

Understanding these rules is critical to avoiding costly delays, so let’s examine the specific requirements for getting your fleet legal and airborne.

Do I need a Part 137 certificate to operate the agricultural drones I import?

We frequently assist our distributors in preparing the technical manuals required for their certification applications, as we know that simply buying a drone does not grant the legal right to spray. Nothing is more frustrating than having a high-performance machine sitting in a warehouse because the operational paperwork was underestimated.

Yes, you must obtain an Agricultural Aircraft Operator Certificate under 14 CFR Part 137 to dispense any economic poisons or chemicals. This applies regardless of the drone’s size. Additionally, you will likely need a Section 44807 exemption to operate legally if your drone weighs 55 pounds or more.

Understanding the Part 137 Requirement

The FAA makes a clear distinction between flying a drone and using a drone to dispense materials. While 14 CFR Part 107 covers general commercial drone flight, it does not automatically authorize the carriage and dispensing of hazardous agricultural chemicals. This is where Part 137 comes in. It is the same regulation that governs manned crop dusters, adapted for unmanned systems.

When you import our spray drones, you are importing "agricultural aircraft." To operate them commercially, you must hold an Agricultural Aircraft Operator Certificate (AAOC) Agricultural Aircraft Operator Certificate ³. This certificate ensures that your operations meet safety standards for handling dangerous goods. dangerous goods ⁴

The Role of Exemptions

Most modern agricultural drones, including the heavy-lift models we manufacture, cannot fully comply with every rule written for manned aircraft (like carrying a physical manual on board or having a seatbelt). Therefore, you need exemptions.

If your drone weighs less than 55 pounds, you operate under Part 107 but need a waiver for Section 107.36 (carriage of hazardous material) and several Part 137 exemptions.

If your drone weighs 55 pounds or more (which applies to most efficient agricultural sprayers), you operate under Part 91 and Part 137. This requires a Section 44807 Exemption. This exemption grants relief from specific regulations that large drones cannot meet.

The Certification Process

The FAA has streamlined this process recently. Previously, you had to submit documents to a local Flight Standards District Office (FSDO) Flight Standards District Office ⁵. Now, much of the process is centralized.

1. Petition for Exemption: You submit a petition for Section 44807 exemption.
2. Submit Manuals: You must provide the FAA with our proprietary Flight Operations Manual and Maintenance Manual.
3. Operator Certificate: You apply for the Part 137 certificate.

Key Differences in Certification

The following table outlines the differences in regulatory requirements based on the operation type.

The 44807 exemption is a critical document. Without it, operating a heavy spray drone is illegal. We recommend starting this paperwork immediately after placing your order, as approval can take several months.

How do FAA weight restrictions affect my heavy-lift agricultural drone operations?

When we design structural frames for our high-capacity SkyRover models, we constantly monitor the 55-pound threshold because we know it fundamentally changes the user experience. Moving from a light payload to a heavy payload increases your efficiency, but it also increases your regulatory burden.

Drones weighing 55 pounds or more at takeoff fall under stricter FAA scrutiny, requiring N-number registration via the Civil Aviation Registry rather than the simple online DroneZone process. You must also prove ownership history and ensure the aircraft is not registered in its country of manufacture.

The 55-Pound Threshold

In the eyes of the FAA, 55 pounds (approx. 25 kg) is the magic number. This weight includes everything: the drone, the battery, and the full payload of liquid.

Most effective agricultural drones easily exceed this weight. For example, a drone carrying 10 gallons of water carries over 80 pounds in payload alone. This places the aircraft firmly in the "large UAS" category.

N-Number Registration Process

For drones under 55 pounds, you can register online at the FAA DroneZone for a small fee FAA DroneZone ⁶, and you get a number instantly.

For drones over 55 pounds, the process is analog and rigorous:

• Paper Application: You must mail physical documents to the FAA Aircraft Registration Branch in Oklahoma City.
• Notarization: Signatures often require notarization.
• Wait Times: It can take weeks or months to receive your N-Number.

De-Registration is Critical

This is a specific pain point for importers. If a drone was tested in China and registered with the CAAC (Civil Aviation Administration of China) Civil Aviation Administration of China ⁷, it cannot be registered in the US until it is de-registered in China.

We ensure our export units are "clean" and not registered in China to prevent this administrative deadlock. However, if you buy second-hand or from less experienced suppliers, you might face a rejection because the drone is still listed in a foreign registry.

Dangerous Goods and Shipping

Weight also impacts how we ship these units to you. The large lithium-ion batteries required to lift 55+ lbs are classified as Classe 9 Marchandises dangereuses.

• UN38.3 Testing: Batteries must have passed UN38.3 safety testing.
• Air Freight Restrictions: Large batteries are heavily restricted on passenger aircraft and often must travel via cargo-only aircraft or sea freight.
• Documentation: The lack of proper MSDS (Material Safety Data Sheet) or UN testing reports can cause Customs to seize the batteries at the port of entry.

Operational Impact of Heavy Drones

Operating a heavy drone changes the requirements for the pilot in command (PIC) and the visual observers (VO).

While the pilot technically holds the same Part 107 license, the Section 44807 exemption will dictate strict operating parameters. It often requires a Visual Observer to be present for all operations, which increases your labor costs.

Is Remote ID compliance mandatory for every agricultural drone I purchase?

Our avionics team installs Remote ID modules directly into our flight controllers because flight controllers ⁸ we understand that non-compliance is a non-starter for US operations. Ignoring this digital requirement creates an immediate risk of grounding, rendering your investment useless from day one.

Yes, Remote ID is mandatory for all drones over 0.55 pounds operating in the US national airspace. Foreign-manufactured drones must either have Standard Remote ID built-in or be equipped with a separate broadcast module, and foreign operators must file a Notice of Identification.

What is Remote ID?

Think of Remote ID as a Remote ID ⁹ "digital license plate." It allows the FAA, law enforcement, and other agencies to identify control station information and the drone's location while it is in flight.

For agricultural operators, this is not optional. Since practically all agricultural drones weigh more than 0.55 pounds (250 grams), every single unit must broadcast this signal.

Methods of Compliance

There are two main ways to comply, and as an importer, you need to know which one your equipment uses:

1. Standard Remote ID: The manufacturer (us) builds the broadcasting capability into the drone's hardware. The drone automatically broadcasts the signal from takeoff to shutdown. This is the preferred method for new industrial equipment.
2. Remote ID Module: If you import an older model or a custom-built rig that lacks internal support, you must attach a third-party module. This module has its own battery or power source and must be turned on before every flight.

The "Foreign Registered" Complication

If you are a US company importing a drone to register it in the US (N-Number), the process is standard. The drone's serial number is linked to your registration.

However, if a foreign entity (like a visiting technician or a foreign service provider) brings a drone that is registered in another country, they face extra steps.

• Notice of Identification (NOI): If the drone is registered outside the US, the operator must submit an NOI to the FAA.
• Session ID: They cannot use a standard US registration number; they must broadcast a specific Session ID.

Choosing the Right Equipment

When sourcing from China, you must verify the Remote ID status.

• Ask for the DoC: Ask the supplier for the Declaration of Compliance (DoC) accepted by the FAA.
• Check the Serial: Ensure the Remote ID serial number is listed on the FAA's public database.

If a supplier ships you a drone without Remote ID capabilities, you will be forced to buy aftermarket modules (costing aftermarket modules ¹⁰ $200-$300 each) and mount them externally using velcro or tape. This is not ideal for agricultural drones that are exposed to water, pesticides, and dust. External modules are potential failure points in harsh farm environments.

Compliance Checklist for Buyers

What steps must I take to register foreign-manufactured drones with the FAA?

We work hard to ensure our invoices and bills of sale are precise because we have seen clients struggle with the strict “citizenship” rules of US aviation registry. Failing to establish clear ownership transfer can leave your imported assets in a legal limbo where they are physically in the US but legally grounded.

You must prove US citizenship or corporate status to register an aircraft. Foreign-manufactured drones require a Bill of Sale showing a clear transfer to a US entity, and heavy drones need proof of de-registration from the origin country to obtain an N-number.

The Citizenship Requirement

The FAA Aircraft Registry is legally reserved for "citizens of the United States." This includes:

• An individual who is a US citizen.
• A partnership where all partners are citizens.
• A corporation organized under US laws (with specific voting/director requirements).

If you are a foreign-owned company operating in the US, you generally cannot register the drone directly. You may need to form a US-based corporation or use a Voting Trust agreement to hold the title of the aircraft. This is a common legal structure for international companies operating assets in America.

The Import-to-Registration Workflow

The timeline for registering a foreign drone (especially one over 55 lbs) is specific.

1. Customs Clearance: The drone enters the US. You pay duties (including potential Section 301 tariffs).
2. Bill of Sale: You must possess an original Bill of Sale (AC Form 8050-2 or equivalent) from the manufacturer to you. It must be signed in ink (or a valid digital equivalent) and trace the chain of ownership.
3. De-Registration Proof: As mentioned earlier, if the drone was ever registered in China (even for testing), the FAA needs a letter from the CAAC stating the registration has been cancelled.
4. Affidavit of Ownership: For new drones that were never registered elsewhere, you may need to submit an affidavit stating that the aircraft was manufactured for export and was never registered in the foreign country.

FCC Compliance at the Border

While the FAA handles the "N-Number," US Customs and Border Protection (CBP) enforces Federal Communications Commission (FCC) rules.

Agricultural drones use radio links for control and video transmission. These radios must have FCC Equipment Authorization.

• Le risque : If your imported drone uses a radio frequency or power level that is not FCC certified, Customs can seize the shipment.
• Our Solution: We ensure our export radios are FCC certified and display the FCC ID clearly on the hardware. As a buyer, you should always request the FCC ID before shipment to verify it in the FCC database.

Manufacturer Support vs. Buyer Responsibility

It is vital to understand where our job ends and yours begins.

By preparing these documents in advance, you avoid the scenario where a drone sits in a hangar for three months waiting for a piece of paper from China.

Conclusion

Importing agricultural drones to the US requires balancing technical ambition with regulatory diligence. You must secure a Part 137 certificate, obtain a Section 44807 exemption for heavy lifting, and navigate the N-number registration process for foreign-made aircraft. By partnering with a manufacturer who understands these specific FAA and Customs hurdles, you can ensure your fleet transitions smoothly from the shipping container to the crop field.
