Products are named differently in the market, but their underlying RCM regulatory pathways are essentially identical. To illustrate this regulatory principle, let us examine a specific case study ;

Electric Toothbrush - Australian RCM Certification

Based on AusRCM Compliance's long-term expertise and deep cultivation in Australia-New Zealand RCM certification, this product must go through complete testing and compliance procedures to be legally placed on the market for sale.

Step 1: EMC Testing Standards

According to the electromagnetic compatibility regulatory arrangements of the Australian Communications and Media Authority (ACMA), electric toothbrushes—as typical personal care small appliances containing switching circuits, digital controls, or wireless modules—fall within the scope of mandatory electromagnetic compatibility and radio regulation, and must comply with the following corresponding test standards:

• AS/NZS CISPR 14.1: Electromagnetic compatibility requirements for household appliances, electric tools, and similar apparatus, applicable to motor-driven rotating/vibrating products such as electric toothbrushes.

• AS/NZS 4268: Short-range radio equipment standard. If the electric toothbrush is smart-enabled and contains internal Bluetooth or Wi-Fi wireless transmission modules to connect to a smartphone app, it must pass this radio frequency technology standard test and obtain the corresponding RF/EMF evaluation reports.

• ETSI EN 300 328: Applicable to wideband transmission systems operating in the 2.4 GHz ISM band (such as Bluetooth in smart toothbrushes). This standard mainly evaluates radio frequency indicators such as frequency occupancy, transmission power, and spurious emissions. It is the core European wireless standard directly corresponding to Australia's AS/NZS 4268. Of course, other European standards such as EN 55014-1, EN 55014-2, EN IEC 61000-3-2, EN 61000-3-3, EN 301 489-1, and EN 301 489-17 are also acceptable, depending on the specific technical characteristics of the product.

Step 2: Safety Testing Exemption (Completely Exempt from Safety Certification and Registration)

Within the electrical safety system (EESS) of Australia and New Zealand, the mandatory scope for low-voltage electrical equipment generally refers to devices with a rated voltage greater than 50V AC (alternating current) or greater than 120V DC (direct current). Therefore, for parts powered by low-voltage DC (such as a built-in 3.7V lithium battery or 5V USB DC input) like the electric toothbrush body itself, legally it does not need to apply for any electrical safety certificate (such as an SAA certificate), nor does it need any product registration in the EESS national database.

⚠️ Special Considerations (Charging Docks & Amazon Compliance Red Lines)

• Wireless Charging Docks / Direct-Plug Adapters: If the electric toothbrush comes with an inductive charging dock or power adapter that plugs directly into the 240V mains electricity, this charging dock belongs to Level 3 (high-risk) mandatory certification products (Battery Chargers) under the EESS framework. It must individually pass the AS/NZS 60335.2.29 standard test, obtain a safety certificate issued by a local Australian RECS body (such as SAA Approvals), and complete registration in the EESS database.

• Amazon Marketplace Additional Interceptions: According to Amazon Australia's lithium battery household appliance compliance policy, personal care appliances with built-in lithium batteries sold on the platform generally require a full-unit safety test report (referencing IEC/EN 60335-2-52 for electric toothbrushes), even if the main body is exempt from EESS registration. Furthermore, the built-in lithium battery pack/cell must mandatorily provide an IEC/EN 62133-2 test report; otherwise, it will face listing removal risks.

Step 3: Issue ACMA-SDoC

As long as the product contains internal chips, switching circuits, electronic control boards (such as PCBs controlling vibration modes), or Bluetooth wireless modules, an ACMA-SDoC (Supplier's Declaration of Conformity) must be issued by a local Australian Responsible Supplier. Otherwise, the product will still be considered as having an incomplete compliance chain.

Step 4: Affix the Statutory Regulatory Mark (RCM Label)

Only when the product meets the applicable electromagnetic compatibility and radio frequency standards, and its accompanying 240V charging dock has completed the relevant SAA safety certification and database binding, can the compliance mark be legally affixed:

• At this point, the unique RCM mark must be legally affixed on the surface of the electric toothbrush body (usually on the bottom of the handle or the back rating label), outer packaging, and user manual. The height of the mark must not be less than 3mm.
