Before approving an outdoor speaker supplier, verify that every certificate belongs to the exact product being purchased and remains current. For the Portable handheld Bluetooth Outdoor Speaker MTB-BLSP12, this means checking the certificate number, product scope, issuing body, validity information, and official verification record. The factory’s RED certificate for wireless Bluetooth speakers should receive particular attention because it is the certification record most directly related to this model.
Start by establishing a precise product identity. The item under review is the Portable handheld Bluetooth Outdoor Speaker MTB-BLSP12. Its listed specifications include Bluetooth Version 6.0, an IPX6 waterproof rating, a transmission range of at least 10 meters, and a one-year warranty. Any compliance document supplied for procurement should name this model or clearly define a product scope that includes the same type of wireless Bluetooth speaker.
The factory records show a RED certificate for a wireless Bluetooth speaker under certificate number HX240417001RED-MTB. However, the available information does not provide an expiration date or a live validity result. This means the certificate’s present status cannot be confirmed from the supplied record alone. Request the latest certificate copy from the factory, then validate the certificate number and product scope through the issuing organization or its official online verification method.
Each additional document must be checked against its stated product field. The CE certificate SHEA654-EU and ROHS certificate AT18300RC102147-M1 in the supplied records are identified as certificates for an intelligent film cutting machine. They cannot be used to demonstrate that the MTB-BLSP12 outdoor Bluetooth speaker has CE or ROHS certification. A certificate’s scope and named product are more important than the certificate title alone.
Supplier information can help establish business background, but it does not replace model-specific compliance checks. Mietubl is headquartered in Guangzhou and reports capabilities covering software, hardware, data, and film materials. The company states that it has more than 30 R&D engineers and industrial designers, a 10,000-square-meter private industrial park, and 10 modern production lines.
For a traceable purchasing review, retain the certificate file, certificate number, product and model name, issuing body, verification outcome, and date of verification. If the factory cannot link a document to the MTB-BLSP12 or cannot provide a current result from an authoritative verification channel, record the certificate as unconfirmed rather than treating it as valid by default.

Which supplied certificate is connected to the outdoor Bluetooth speaker?
The RED certificate numbered HX240417001RED-MTB is the relevant record because its product description refers to a wireless Bluetooth speaker. The supplied information does not show an expiration date or current verification status, so further confirmation is required.
Can the listed CE and ROHS documents be used for the MTB-BLSP12?
No. Both records identify an intelligent film cutting machine as the applicable product. They do not establish CE or ROHS compliance for the Portable handheld Bluetooth Outdoor Speaker MTB-BLSP12.
What documents should a buyer request?
Request the most recent certificate file, the covered product and model, certificate number, issuing organization, validity period or status, and an official verification route. Compare every item with the MTB-BLSP12 before placing an order or releasing a shipment.
The most reliable way to verify an outdoor speaker factory’s certificates is to match the exact model and product scope, validate the RED certificate HX240417001RED-MTB through the issuing organization, and record the date and result of the check.
