In 2026, Bluetooth SIG pushed the core specification to 6.0, and LE Audio-related Profiles keep expanding. If your product has a BQB certificate under version 5.4, can the old certificate still be used after 6.0 becomes widespread? Do you need to redo the Declaration? How do you determine whether a product change triggers recertification? These are the questions that actually matter in practice.

I. BQB Certificates Have No Fixed Validity Period

Bluetooth SIG has never specified a BQB certificate validity period of three or five years. As long as your product's hardware design hasn't changed and the applicable Bluetooth standard version remains currently valid, the certificate stays effective. SIG's official position is that certificates are permanently valid with no expiration date.

But Bluetooth standards do iterate. Each time SIG releases a new generation core specification, older versions gradually get phased out by the market. When a product's claimed Bluetooth version is rarely used by devices in the market, the designer typically proactively upgrades certification. This isn't SIG mandating it — market demand drives it. Customers seeing a Bluetooth 4.2 product will almost always ask if it can do 5.4, even if the 4.2 certificate is still valid.

Once a DN (Declaration Number) is issued, it's permanently valid and won't automatically lapse. Even if your company later stops paying SIG membership fees, already-issued DNs can still be found in the SIG database. Anyone can verify authenticity on the public web at any time. But during the non-payment period, you can't create new Declarations or modify product information on existing Declarations. One difference from the Wi-Fi Alliance: Wi-Fi Alliance suspends trademark usage rights immediately upon non-payment.

On September 9, 2025, SIG issued a new rule — mandatory across the platform starting 2026. RN (Reference Number, essentially the application number) now has an expiration date. Paid members (Associate/Contributor/Promoter) get a 12-month RN validity period. Free Adopter members only get 6 months. An RN is a certification quota — it can only be used for the initial DN application. Once expired, it's directly voided with no refund. Any EPL (End Product Listing) hanging under it also becomes invalid. This is completely separate from DN permanent validity.

When an Associate downgrades to free Adopter, historical DNs remain permanently valid and normal shipping can continue. Only two restrictions apply: no new Declarations can be created, and no existing Declaration information can be modified. There's no such thing as "advanced features being restricted." Profile protocol validity has nothing to do with membership tier.

  II. When Do You Need to Redo the Declaration?

1.Product hardware changes are a hard recertification trigger. Swapping the Bluetooth chip model, changing antenna design, or adjusting RF matching circuits — all trigger a new Declaration plus full RF testing.

2.RF matching circuits — a point that's easy to get backwards. Before swapping matching components, the company must first conduct its own change evaluation. If you're swapping to the same spec from the same supplier and the complete device RF test results are completely unchanged, just submit a change document. But if RF parameters have changed, that's a Class-3 major change requiring a full retest. You can't privately change components and wait for SIG to audit afterward — the evaluation responsibility sits with the company, not SIG.

3.Adding new Bluetooth Profile functionality also requires a new Declaration. If the product previously only supported A2DP and HFP, and now adds LE Audio-related BAP and PACS Profiles — these aren't in the original Declaration scope. A new Declaration must be created.

But here's the distinction: as long as the RF hardware, antenna, and Bluetooth chip are completely unchanged, RF test data can be reused from the original data. You only need to supplement protocol conformance testing for the newly added Profiles. Only a chip swap requires a full RF retest. LE Audio test facilities differ from Classic Bluetooth — confirm lab qualifications first.

  III. Derivative Declaration Rules

1.Derivative certification is the cost-saving, time-saving path. If Product B is a minor modification of Product A, you can use A's test data for a Derivative Declaration — no need to test from scratch. Self-developed products going through Derivative cost only a few hundred USD, much cheaper than full certification.

2.Derivatives have conditional limits. Changes must fall within SIG-permitted ranges — for example, enclosure size changes, color changes, memory expansion with unchanged Bluetooth protocol stack. Any RF performance-related change — whether it qualifies for Derivative isn't based on a fixed number. An SIG-accredited lab must evaluate it against the Change Evaluation Matrix holistically. Minor antenna gain fluctuation, if the complete device's actual transmit power, spurious emissions, and frequency deviation still match the parent version, can still go through Derivative.

3.Derivative Declaration validity is tied to the parent Declaration. If the parent Declaration needs to be rebuilt due to hardware changes, and the derivative product's hardware parameters are completely identical to the new parent version, the lab can re-do the Derivative based on the new parent version after evaluation — it's not necessarily a full retest from scratch.

  IV. Renewal Is Essentially Membership Renewal

1.BQB renewal isn't renewing the certificate itself — it's renewing SIG membership. Associate membership fee cycles don't follow the calendar year (January to December). They run twelve months from the joining date. Only Promoter founding members are billed on a calendar year basis. Mid-year joiners have their own independent fee start and end dates. Many people get this confused.

If fees go unpaid for more than six months, SIG suspends Bluetooth trademark usage rights and blocks new Declarations. But existing DNs remain valid. One critical caveat: after non-payment, product hardware absolutely cannot be changed. And packaging and manuals must no longer carry the Bluetooth logo. Continuing to print it constitutes trademark violation. Non-payment doesn't mean you can ship carefree.

2.Membership fees vary by membership type and company annual revenue. Adopter pays no annual fee but can only do Derivatives. Associate pays several thousand USD annually for full-process certification. Principal pays over ten thousand USD with larger quotas. SIG's IIP (Innovation Incentive Program) is for small businesses with annual revenue under one million USD that have never applied for BQB before — not ten million USD.

SIG conducts random audits of certified products. After receiving an audit notice, you have 45 days to submit compliance proof materials. Failure to produce may result in Declaration revocation. After a product is discontinued, it's recommended to proactively submit an EOL (End of Life) declaration. Once SIG's system marks the product as discontinued, market compliance audits for that product cease — but DN validity isn't deleted and existing inventory shipping isn't affected. This isn't the same as reducing audit probability. The logic needs to be clear.
