How Long Does Bluetooth NCC Certification Take?

According to the requirements of Taiwan’s National Communications Commission (NCC) for Bluetooth product certification, the duration mainly depends on the completeness of documentation, test and rectification results, and product complexity. The typical timeline and key processes are as follows:

Standard Certification Timeline

1. Regular duration: A full process typically takes 3–4 weeks (about 20–28 working days).

2. Expedited cases: If documents are complete and tests pass on the first attempt, some agencies can shorten it to 2–3 weeks.

Certification Process & Time Allocation

The certification process proceeds in stages, with reference timelines as follows:

1. Document review & project initiation (1–3 days): Submit product specifications, circuit diagrams, etc., confirm quotation, and make payment.

2. Pre-testing & rectification (1–2 weeks):

 - Laboratory conducts pre-tests (RF performance, EMC, etc.).

 - If issues are found (e.g., RF exceeding limits), rectification and retesting are required, possibly extending this phase by 1–2 weeks.

3. Witness testing & reporting (1 week):

 - Local certification body in Taiwan conducts witness testing to ensure compliance.

4. Review & certification issuance (1 week):

 - NCC reviews the test report and issues the certificate.

Key Factors Affecting Duration

- Missing documents: Incomplete circuit diagrams, antenna specifications, or ISO9001 certificates delay project initiation.

- Prototype requirements: Four samples are required (2 normal units + 2 fixed-frequency units). Fixed-frequency units need SMA RF connectors soldered. Poor preparation may slow down testing.

- Product complexity: Multi-band or high-power designs may increase testing difficulty.

Certificate Validity & Maintenance

- No fixed validity period: Certificates remain valid indefinitely, provided product design, antenna specs, and test standards remain unchanged.

- Renewal conditions: If Taiwan revises RF standards (e.g., LP0002), retesting is required to maintain validity.

Summary & Recommendations

To shorten certification time, ensure:

1. Complete documentation: Circuit diagrams, BOM, antenna specifications, etc.

2. Compliant prototypes: Fixed-frequency samples must meet test requirements.

3. Experienced certification body: Assist with pre-checks and rectifications to avoid repeated testing.

For an accurate timeline estimate, it is recommended to submit product specifications to the certification body for pre-assessment.
