Compliance of R7 with regulations
Compliance and Regulatory Status
The R7 fuel-saving device is a passive, non-powered technology designed for use with gasoline and diesel engines. The device is manufactured using aluminum and PET — polyethylene terephthalate.
R7 does not contain radioactive materials, batteries, microchips, amplifiers, transmitters, signal generators, Bluetooth modules, Wi-Fi modules, cellular modules, or any other active electronic components. It does not intentionally generate, amplify, process, or transmit radio-frequency signals.
The device is a passive conductor-based structure. From the perspective of its physical operating principle, R7 may be classified as a passive antenna-type device. From the perspective of its manufacturing method, it may also be described as a printed multilayer conductor structure.
R7 is intended to operate as a passive accessory. It is not a telecommunications device, not a radio transmitter, not a wireless module, not a jammer, and not an active electromagnetic-emission device.
Technical Classification
R7 has no independent electrical power source and no active radio-frequency functionality. It does not operate as a transmitter, receiver, telecommunications device, wireless communication device, amplifier, or active radio equipment.
The European Commission’s guidance on the Radio Equipment Directive 2014/53/EU — RED distinguishes between active and passive antennas. According to this guidance, active antennas contain active electronic components interacting with the RF signal, while all other antennas are generally considered passive. The same guidance states that passive antennas placed on the market as a single commercial unit are not covered by RED. (European Commission)
Accordingly, R7 should be assessed as a passive, non-transmitting product. If R7 is supplied and installed as a standalone passive device and is not integrated with any active radio-transmitting equipment, no radio-equipment certification is expected solely on the basis of radio regulations.
If R7 is combined with any active transmitter, powered RF module, wireless communication unit, electronic controller, or other active radio equipment, the complete system should be assessed separately under the applicable regulations of the destination country.
Customs Classification
R7 is manufactured as a printed multilayer conductor structure, consisting of conductor elements and contact areas arranged in several layers.
Depending on the interpretation applied by the customs authority in the destination country, two HS-code approaches may be considered.
HS Code 8534.00 / 8534.00.11 may be considered when R7 is classified according to its method of production as a printed circuit or printed multilayer conductor structure. This approach is based on the fact that the device consists of printed conductor elements and contacts without active electronic components.
HS Code 8517.71 may be considered when R7 is classified according to its physical operating principle as an aerial, antenna-type device, aerial reflector, or part suitable for use therewith. The WCO Harmonized System includes subheading 8517.71 for aerials and aerial reflectors of all kinds and parts suitable for use therewith. (World Customs Organization)
The final HS code should always be confirmed by the importer, customs broker, or the relevant customs authority in the destination country.
Regulatory Position by Jurisdiction
European Union
In the European Union, radio equipment is regulated under the Radio Equipment Directive 2014/53/EU — RED.
The European Commission’s RED Guide explains that antennas may be divided into active and passive types:
https://ec.europa.eu/docsroom/documents/33162/attachments/1/translations/en/renditions/native
Active antennas include active electronic components interacting with the RF signal, while other antennas are generally considered passive. The same guidance states that passive antennas placed on the market as a single commercial unit are not covered by RED. (European Commission)
R7 is a passive device without a transmitter, receiver, battery, amplifier, microchip, or powered RF component. Therefore, when supplied as a standalone passive device, R7 should not be treated as radio equipment under RED.
If R7 is ever integrated into or supplied together with active radio equipment, the complete product or system would need to be assessed separately under the applicable EU requirements.
United States
In the United States, radio-frequency devices and radio transmitters are regulated by the Federal Communications Commission — FCC.
FCC Part 15 applies to radio-frequency devices, including intentional, unintentional, and incidental radiators. R7 is not an intentional radiator, not a transmitter, and not a powered RF device. (eCFR)
R7 is not supplied as part of an active radio-transmitting system. Therefore, no FCC equipment authorization is expected solely for R7 as a standalone passive device.
If R7 is combined with any active transmitter, wireless module, electronic control system, or powered RF equipment, the complete system should be reviewed separately for FCC compliance.
For vehicle installation, R7 should be installed only as a passive accessory and should not interfere with the vehicle’s electrical control systems, safety systems, emissions-control systems, onboard communication networks, or manufacturer-certified configuration.
FCC ( Federal Communications Commission) gives the following explanation on passive antennas:
https://apps.fcc.gov/kdb/GetAttachment.html?id=5qBZ5Zw0y5gQlfkLm6z6Uw%3D%3D&desc=353028%20D01%20Antennas%20Part%2015%20Transmitters%20v01r01&tracking_number=39060
Question: What are the equipment authorization requirements for marketing and selling passive
antennas.
Answer: Passive replacement antennas by themself do not require an FCC equipment authorization
and thus, by themselves do not require certification (no associated FCC ID number) nor are they
subject to SDoC.
A passive antenna is entirely comprised of passive components(no electronics). An active antenna uses electrically powered components for amplifiers, directivity,low-noise amplifiers (LNAs), power amplifiers (PAs), active filtering (tunable filters or switched filter banks), or switched antenna radiator elements and requires an FCC equipment authorization as part of a system
The installation of consumer-owned antennas is regulated by the FCC in the USA.
On the website of FCC, it is said no permissions are necessary for such installation

India
In India, wireless and radio-related equipment is regulated under the Telecommunications Act, 2023, the Indian wireless regulatory framework, and the WPC/DoT equipment-approval procedures.
The Telecommunications Act, 2023 defines “radio equipment” as telecommunication equipment used or capable of being used for telecommunication by means of Hertzian or radio waves. The Act also provides that authorization may be required for possessing radio equipment.
India’s WPC ETA process is generally relevant to products operating in de-licensed frequency bands and to products containing one or more RF modules. The official WPC ETA FAQ refers to products having inbuilt RF modules and requires RF test reports for such modules or products.
R7 has no RF module, no wireless transmitter, no telecom function, no SIM module, no Bluetooth, no Wi-Fi, no cellular function, and no active radio-frequency electronics. On this basis, R7 should not require WPC ETA, radio-equipment authorization, or a separate radio license when installed as a standalone passive accessory on a vehicle.
For installation on vehicles in India, the key compliance point is that the device should not alter the vehicle’s registered or manufacturer-certified characteristics. Section 52 of the Motor Vehicles Act, 1988 concerns alteration of motor vehicles and restricts changes that make the vehicle particulars differ from those originally specified by the manufacturer or reflected in the registration certificate. (India Code)
Therefore, R7 should be installed only in a way that does not modify the vehicle structure, engine parameters, fuel system, safety systems, emissions system, registration data, or manufacturer-certified specifications. If an installation changes any registered technical characteristic of the vehicle, local RTO confirmation may be required.
China
In China, radio-transmission equipment is regulated under the national radio regulatory framework and the rules administered by the Ministry of Industry and Information Technology — MIIT.
China’s Radio Transmission Equipment Management Provisions define radio transmission equipment as equipment that transmits radio waves for radio services. The same provisions state that production or import of radio transmission equipment for sale and use in China generally requires radio transmission equipment type approval. (dcj.mofcom.gov.cn)
R7 does not transmit radio waves, does not contain an RF transmitter, does not operate as radio transmission equipment, and does not perform wireless communication. Therefore, when supplied and installed as a standalone passive device, R7 should not require China SRRC radio type approval solely on the basis of radio-transmission regulations.
If R7 is combined with any active wireless module, transmitter, connected electronics, powered RF system, communication device, or electronic controller, the complete product should be reviewed separately for SRRC, CCC, network access, or other applicable Chinese requirements.
For vehicle installation in China, R7 should be installed only as a non-structural passive accessory. It should not change the vehicle’s registered technical characteristics, exterior configuration, safety systems, emissions systems, engine control systems, or manufacturer-approved vehicle specifications. If installation affects any registered vehicle parameter, local vehicle-registration or approval requirements should be checked before use.
Canada
In Canada, certification of radio apparatus and broadcasting equipment is administered by ISED — Innovation, Science and Economic Development Canada. RSP-100 sets out the certification procedure for radio apparatus and broadcasting equipment that fall under applicable radio and broadcasting standards. (ised-isde.canada.ca)
Because R7 is passive, non-powered, and does not function as radio transmitting equipment, it should be reviewed as a passive accessory rather than active radio apparatus.
If R7 is supplied or integrated with active RF equipment, the complete system should be assessed separately under Canadian radio-equipment requirements.
Installation and Use
R7 is intended to be installed as a passive accessory device. It should not be connected to the vehicle’s ECU, fuel injection system, ignition control system, safety systems, emissions-control systems, onboard diagnostics, or onboard communication networks unless such installation is specifically approved by qualified technical personnel.
The device should be installed in a manner that:
- does not change the vehicle structure;
- does not affect registered vehicle specifications;
- does not interfere with safety systems;
- does not modify the engine, fuel system, emissions system, or electrical control systems;
- does not create active electromagnetic emissions;
- does not include any radio transmitter or wireless communication function;
- does not require electrical power for operation.
R7 is designed as a passive device for improving fuel-efficiency performance in systems using gasoline and diesel engines, while keeping installation simple and non-invasive.
