COSYU is a B2B manufacturer of phone cases and mobile device accessories, operated by COSYU Technology Co., Ltd. and based in Shenzhen. Its website highlights one-stop OEM/ODM services covering design, mold making, injection molding, UV printing, epoxy doming, packaging, and customs export. Core products include resin/epoxy phone cases, aramid fiber cases, mother-of-pearl cases, transparent TPU cases, leather cases, AirPod protective cases, screen protectors, lanyards, and laptop skins.
From an e-commerce supply chain perspective, COSYU’s main value lies in its factory-based customization capabilities. It claims to have clean workshops, automated production lines, 3 automated epoxy doming lines, an in-house testing lab, and certifications including ISO9001, BSCI, RoHS, and REACH. Its service models are divided into ODM, OEM, and One-Stop Solution: ODM MOQ is 500 pieces, OEM MOQ is 300 pieces, and the one-stop solution MOQ is 200 pieces. The customization process includes 1–2 days for inquiry response, 3–7 days for design, 7–10 days for sampling, 15–25 days for production, and 3–7 days for QC and shipping. This makes it suitable for sellers that need new product development and branded packaging.
The website does not disclose mold fees, sample fees, shipping costs, payment terms, or payment methods. It only provides reference prices for some products, such as transparent TPU cases at $9.99, aramid fiber cases at $12.99, epoxy resin cases at $15.99, and leather cases at $18.99. Overall, it operates more like a quotation-based supplier than an online transaction platform. Sellers will need to confirm tiered pricing, lead times, and customization costs via email, WhatsApp, or inquiry form.
The advantages are that its product categories are fairly focused, forming a complete supply chain around phone cases and 3C protective accessories; it supports customization of logos, colors, materials, and packaging; and its MOQ information is relatively clear, making it somewhat friendly to cross-border sellers testing products in small batches. The drawbacks are also obvious: the official website contains inconsistent statements about founding year, factory size, and employee count, such as 2005/2013, 5000㎡/10000㎡, and 150+/200+, so an on-site or video factory audit is recommended. Payment terms, after-sales support, logistics costs, and wholesale pricing are also not transparent.
COSYU is better suited for Amazon sellers, independent online stores, offline distributors, and mid-to-high-end phone case brands looking for an OEM/ODM supplier. It does not look like an e-commerce platform where orders can be placed directly. The available text does not indicate whether access from China is stable. For price comparison, sellers can also check Alibaba.com, Made-in-China.com, Global Sources, or local 3C accessories factories in Shenzhen.
