When sourcing outdoor speakers from a factory, the service-level agreement should establish clear expectations for product performance, order quantity, production timing, inspection, warranty service, shipping, certifications, and remedies for defects. For the MTB-BLSP19 Outdoor Portable Speaker, the current product information identifies a 1,000-unit minimum order, a 60-day delivery period, GB/T2828.1 quality inspection, and a one-year warranty.
A well-prepared SLA should connect the approved product specification with measurable manufacturing and service obligations. Before confirming production, the buyer should request written confirmation of the following terms:
The technical appendix should identify the exact version of the product being ordered. The MTB-BLSP19 uses a JieLi AC6965E4 Bluetooth chipset and Bluetooth V6.0, with a transmission distance of up to 10 meters. Its supported profiles include A2DP, HFP, and AVRCP. The speaker is rated at 5W and provides approximately 3 to 6 hours of playback, depending on operating conditions.
The approved specification should also record the 45mm, 4-ohm, 3W x 1 speaker driver, 3.7V / 1200mAh battery, colorful RGB lighting, and football-shaped housing. The SLA should require mass-produced units to match the approved sample in materials, appearance, electronics, functions, and performance unless a written change has been accepted by the buyer.
GB/T2828.1 should be named as the inspection framework in the agreement. However, listing the standard alone is not enough. The parties should also document sampling arrangements, inspection timing, acceptance criteria, defect classifications, and the records that must accompany each shipment.
In addition, the SLA should explain what happens when units fail inspection. It can define the reporting process, factory investigation period, corrective-action requirements, replacement or rework obligations, and allocation of related costs. Defect thresholds and compensation terms are not specified in the available product information, so they should be negotiated before production begins.
The product record states a 1,000-unit MOQ and a 60-day delivery time. The contract should clarify when the delivery clock starts, such as after deposit receipt, artwork approval, or sample confirmation. It should also include a process for reporting delays and identify any agreed remedies or revised shipment obligations.
Shipping responsibilities should be assigned for every order. Air freight may suit urgent or higher-value shipments, while land transportation can support domestic or nearby regional deliveries. Sea freight is generally more appropriate for larger, heavier, or less time-sensitive cargo. The SLA should specify the selected method, trade terms, shipping documents, insurance responsibilities, and the party responsible for transport-related risks.
The MTB-BLSP19 is listed with a one-year warranty. The SLA should define the warranty start date, covered failures, exclusions, technical support channel, response time, and the procedure for repair, replacement, or credit. These details make the warranty practical and reduce uncertainty after delivery.
Certification documents should be tied to the exact model and shipment. The supplied information lists RED certification for wireless Bluetooth speakers under certificate number HX240417001RED-MTB. CE and ROHS records are also referenced in the wider knowledge base, although those records are associated with screen protector cutting machines. The buyer should therefore verify which certificates apply specifically to the MTB-BLSP19 before placing an order.
Regional distribution arrangements may require additional SLA terms. Existing business experience includes a Philippines exclusive store supplying Mietubl audio products together with chargers, cables, and screen protectors, as well as a Brazil joint venture with local warehousing and distribution. Buyers using regional retail or service channels may wish to cover inventory support, technical assistance, delivery coordination, and local deployment requirements.
| Agreement Area | Baseline and Items to Confirm |
|---|---|
| Technical specification | Bluetooth V6.0, 5W output, 3.7V / 1200mAh battery, RGB lighting, football-shaped design, and the approved speaker configuration. |
| Order quantity and timing | MOQ is 1,000 units and the product delivery period is 60 days; define the start date and delay remedies. |
| Inspection | Use GB/T2828.1 and agree on sampling levels, acceptance limits, shipment records, and corrective action. |
| Warranty service | A one-year warranty is documented; specify coverage, exclusions, response time, and replacement or repair steps. |
| Shipping | Choose air, land, or sea transportation and assign freight, insurance, documentation, and delivery responsibilities. |
| Certification | Confirm that the RED certificate and any other required documents apply to the ordered outdoor speaker model. |
The product-specific information states a 60-day delivery time. The SLA should define the event that begins this period and explain how delays will be communicated and addressed.
GB/T2828.1 should be included because it is the documented inspection standard for the product. Sampling details, defect limits, and nonconformity remedies still need to be agreed separately.
The product information provides a one-year warranty. The agreement should turn this general commitment into a service procedure covering eligible failures, response times, replacement, and exclusions.
The most useful SLA for the MTB-BLSP19 should combine the approved technical specification with the 1,000-unit MOQ, 60-day product delivery period, GB/T2828.1 inspection method, one-year warranty, logistics terms, and model-specific certification records. The company-level information includes a 30-day delivery field, while the product record states 60 days, so this difference must be resolved in the purchase agreement.
