Standards & Compliance
The ETENWOLF HB3 air pump was tested against the following regulatory standards and measurement procedures to confirm electromagnetic compatibility and radio frequency emissions compliance for sale in the United States.
- 47 CFR Part 15, Subpart B (October 2020) — The primary FCC rule governing unintentional radiators. Subpart B sets the limits for conducted and radiated emissions from digital devices to prevent harmful interference with authorised radio communications.
- ANSI C63.4:2014 + A1:2017 — The American National Standard measurement procedure for radiated and conducted emissions from unlicensed intentional, unintentional, and exempted digital devices. This standard defines the test site requirements, instrumentation, and measurement methodology used during evaluation.
- FCC Section 15.19(a) — Labeling requirement mandating that devices subject to Part 15 carry the prescribed compliance statement or FCC identifier on the product label.
- FCC Section 2.906 — The rule governing the SDoC process, requiring that a declaration be on file with the responsible party before the device may be marketed in the USA.
Compliance with these standards demonstrates that the HB3 air pump does not cause harmful radio frequency interference under normal operating conditions at its rated input of DC 5V / 2A.
Validity & Certification Body
The Verification of Conformity (VoC) bearing Reference No. WTH25H09260769E was issued on October 16, 2025 and is valid subject to the following conditions:
- The responsible party (Guangdong Bestek Technology Co., Ltd.) must retain the underlying test report and all supporting compliance documentation.
- Documentation must be made available to the Federal Communications Commission (FCC) upon request.
- The VoC is based on a single sample test and does not constitute an assessment of the entire production run. Ongoing production must maintain compliance.
- The FCC SDoC logo may be applied to the product label on a voluntary basis, provided the device fully complies with all SDoC procedures.

Frequently Asked Questions
- What does FCC SDoC mean for the ETENWOLF HB3 air pump?
-
FCC SDoC stands for Supplier’s Declaration of Conformity. It means that Guangdong Bestek Technology Co., Ltd., as the responsible party, has tested the ETENWOLF HB3 air pump against FCC Part 15 Subpart B requirements and declares — without requiring FCC pre-approval — that the device meets the applicable radio frequency emission limits. This authorisation pathway allows the product to be legally marketed and sold in the United States.
- Which test standard was used to evaluate the HB3 air pump?
-
The HB3 was evaluated using 47 CFR Part 15 Subpart B (October 2020) as the regulatory requirement, and the measurement procedure followed was ANSI C63.4:2014 + A1:2017. Testing was carried out by Waltek Testing Group HCT (Shenzhen) Co., Ltd., and the device was found fully compliant.
- Does the FCC SDoC certificate cover all units produced?
-
No. As stated in the certificate, the VoC (Reference No. WTH25H09260769E) is based on a single test of one sample of the device. It does not imply an assessment of the entire production. The manufacturer is responsible for ensuring that all production units maintain the same level of compliance as the tested sample.
- Is the FCC logo required on the ETENWOLF HB3 product label?
-
The FCC logo is optional for SDoC-authorised products. Its use is voluntary but permitted only on products that fully comply with the SDoC procedures. However, the product label must comply with the mandatory labeling requirements set out in FCC Section 15.19(a), which typically requires a compliance statement identifying the device as subject to Part 15 rules.
Related Documents
The following certification and compliance documents are relevant to the ETENWOLF HB3 air pump and are recommended to provide a complete compliance profile for global markets:
- CE Declaration of Conformity — Required for marketing the HB3 in the European Union, covering applicable directives such as the Radio Equipment Directive (RED) or Low Voltage Directive (LVD) and relevant IEC / ISO harmonised standards.
- RoHS Compliance Report — Confirms that the HB3 meets RoHS restrictions on hazardous substances in electrical and electronic equipment, required for EU and UK market access.
- REACH Substance Declaration — Documents conformity with REACH regulations regarding substances of very high concern (SVHCs) present in the product.
- KC Certification — Required for the South Korean market under the KC Mark scheme, covering electromagnetic compatibility and safety requirements.
- UN 38.3 Test Report — If the HB3 contains or is shipped with a lithium battery, a UN 38.3 transport test report is required for international air and sea freight compliance.
- FCC ID Grant of Equipment Authorization — If a future HB3 variant incorporates intentional radio transmitters (e.g., Bluetooth), a full FCC ID certification would be required in addition to the current SDoC.
