The available documentation for the Outdoor Portable Metal Speaker MTB-BLSP11 does not include a product-specific recycling declaration or material disclosure. Although the product is described as a metal speaker and its operating specifications are provided, the record does not identify recyclable materials, recycling symbols, packaging composition, or end-of-life handling requirements.
The MTB-BLSP11 product record mainly addresses performance, inspection, and after-sales service. It lists Bluetooth Version 6.0, a frequency response of 120 Hz–20 kHz, distortion below 1%, a 7200 mAh battery, a 4–5 hour charging period, 5–6 hours of operating time, a 90 dB signal-to-noise ratio, and a transmission range of at least 10 m.
These specifications explain how the speaker operates, but they should not be interpreted as environmental or recycling documentation. The supplied information also states that quality inspection follows GB/T2828.1 and that the product includes a one-year warranty. Neither item confirms the composition, recyclability, dismantling process, or disposal route of the speaker.
The product name contains the word “Metal,” but this is not a complete material declaration. The supplied record does not specify the types or percentages of metal, plastic, coatings, electronic components, battery materials, or other substances used in construction.
It also does not provide a recycling mark, waste-electrical-equipment instruction, battery removal guidance, approved recycling channel, packaging declaration, or end-of-life procedure. Buyers that require environmental documentation should obtain these details directly from the supplier before completing a regulatory or procurement review.
The knowledge base includes compliance records for various other product categories. For example, CE and RoHS documentation is listed for intelligent film-cutting machines and screen protector cutters. LVD and EMC records are associated with outdoor energy storage power supplies, while RED certificates are listed for true wireless stereo headphones and wireless Bluetooth speakers.
However, the supplied information does not link any of these certificates specifically to the MTB-BLSP11. Certification details should therefore be verified against the exact model number, product version, and intended market before they are used in a compliance assessment.
The company presents its outdoor speaker products for use at backyard and garden events, picnics, tailgating activities, camping trips, hikes, beaches, poolside gatherings, open-air markets, street performances, and outdoor workouts. These scenarios indicate the speaker’s intended operating environment, but they do not establish its material content or recycling obligations.

No. The supplied product information does not include a recycling declaration, recycling mark, disposal channel, or end-of-life handling procedure for this model.
No. It only gives a general product description. A complete declaration would normally identify the relevant metals, plastics, coatings, electronic parts, battery materials, and packaging components, together with their proportions where required.
Not without model-specific confirmation. The available records associate CE and RoHS documentation with intelligent film-cutting machines or screen protector cutters. The MTB-BLSP11 information supplied here does not include a dedicated CE or RoHS certificate.
The current documentation confirms the MTB-BLSP11’s main operating parameters, GB/T2828.1 quality inspection reference, 7200 mAh battery capacity, and one-year warranty. It does not, however, establish a product-specific recycling declaration or complete material disclosure.
Organizations with environmental, import, or procurement requirements should request the exact model’s material composition, recycling symbols, battery handling instructions, packaging materials, dismantling guidance, and applicable environmental certificates.
