Best Source International Co., Ltd. (BSI) is a prominent China-based manufacturer, distributor and international business solutions provider established in 1999. With more than 25 years of industry experience and a workforce of over 100 employees, the company has evolved from a professional sourcing firm into a comprehensive enterprise. BSI operates 20 production lines and 12 high-speed SMT lines, maintaining ISO 9001 and ISO 14001 certifications.
Computing and mining hardware forms the core of our business. Our range covers graphics cards and AI GPUs, servers and server-related hardware, ASIC miners, CPUs, memory, SSDs and hard drives. As a major supplier of cryptocurrency mining hardware from leading brands such as Bitmain, MicroBT and Innosilicon, alongside high-performance GPU mining rigs and graphics cards from NVIDIA, AMD and MSI, we work with distributors, resellers, system integrators and business buyers to review exact models, configurations, compatibility and quantities. Product condition, availability, warranty terms and delivery schedules are confirmed for each order.
Alongside our core hardware business, BSI supplies smart locks for homes, rental apartments, offices and hospitality projects. We help customers review door compatibility, lock body specifications, access methods and connectivity requirements. Fingerprint access, passcodes, cards, mobile apps and other functions vary by model. Software compatibility, gateway requirements and customization options are discussed according to the selected product and project scope.
BSI also offers logistics and palletizing robotics for factory and warehouse applications, including AMR/AGV transport robots, automated forklifts and palletizing equipment. These projects follow a separate requirements review covering payload, site layout, operating conditions, workflow and system integration. Equipment selection, customization, installation support and acceptance criteria are defined according to the agreed project scope.
Reliable supply starts with clear specifications. We work with customers and supply partners to confirm product requirements and coordinate the checks agreed for each order, which may include model and configuration verification, condition checks, functional testing and packaging inspection. Relevant certifications and supporting documents are reviewed for the specific model and destination market. For robotics projects, inspection and acceptance requirements are defined separately to reflect the equipment, operating environment and integration scope.
Whether you are sourcing computing hardware, ASIC miners, smart locks or robotics equipment, our team works with you to define specifications and supply requirements. For selected products, we can discuss configuration, branding, packaging and other customization requests with the relevant teams or supply partners. Feasibility, minimum order quantities, costs and lead times are confirmed before an order is placed.
BSI supports product inquiries, quotations, order follow-up, shipping arrangements and after-sales communication. Based on the agreed order terms, we coordinate packing, shipping documentation and delivery requirements with customers and logistics partners. Shipping methods, customs responsibilities and destination services are confirmed for each shipment.
As a verified supplier with annual revenue exceeding 250 million USD, BSI serves over 10,000 active customers across North America, Europe, the Middle East and Africa. Since 2011, the company has held a leadership role as the President Company of Council for the Shenzhen E-Commerce Chamber.
