About Calowv – B2B Mobile Phone Parts & Accessories Supplier
Calowv supplies mobile phone parts and consumer electronics to wholesalers, distributors, importers and professional repair businesses. Our own brand, Calowv, covers screens, batteries, phone cases, cables, smart watches and 3C repair accessories – supported by a 5,000 m² facility and export experience in 56+ countries.
Nine product lines, one order, one shipment: we work as a single point of supply for buyers who need mixed models and categories. Requirements are confirmed item by item, goods are inspected and packed before dispatch, and every shipment leaves with a commercial invoice, packing list and HS code information for your broker.
Who We Are
Established in 2017, we operate from Shenzhen with a 5,000 m² facility in Shenzhen. We serve more than 100,000 customers worldwide, from single-store repair shops to regional distributors and importers.
Our range covers nine product lines: phone screen assemblies, batteries, phone cases, data cables, kids smart watches, phone holders, travel adapters, game consoles and 3C repair parts.
We focus on practical order execution: confirming the exact model and version, checking goods before shipment, keeping communication clear, and supporting buyers after delivery.
Because we buy and ship across the same nine lines, buyers can consolidate a mixed-model, mixed-category order into one purchase plan instead of managing several suppliers. MOQ is confirmed per item, OEM/ODM is supported on the same lines, and wholesale pricing is confirmed before you commit.

Our Journey

- 2017 · Founded
Calowv was established, starting with mobile phone parts and accessory trade for overseas buyers. The first orders were screen assemblies, batteries and cases for repair shops and small distributors.
- Facility Expansion
We grew our operations into a 5,000 m² facility in Shenzhen, adding warehouse capacity, inspection areas and packing lines. Model-based shelving, a dedicated inspection bench and separate packing stations let us handle mixed orders without splitting them across locations.
- Global Reach
Our customer base expanded across 56+ countries and regions, serving more than 100,000 customers and repeat wholesale accounts. Export documents, HS code information and destination-specific packing are prepared in-house for every shipment.
- Today · Calowv Brand
The Calowv brand covers nine product lines with OEM/ODM support, flexible MOQ and export packing for mixed-model wholesale orders. Our ordering, shipping, duties and returns terms are published openly, so buyers know how an order will run before they place it.
Our Operations Facility
Five working areas keep orders accurate – from inquiry and model confirmation to inspection, packing and after-sales support. Each order moves through these areas in sequence, and the same team follows it from the first message to delivery.

Office & Customer Service
The office team handles inquiries, quotations, model confirmation and order coordination, keeping every order documented from the first message to delivery. Quote requests are usually answered within one business day, and nothing goes into production until you approve the Proforma Invoice.
Inspection & Testing
Appearance checks, model verification and product-specific functional testing are carried out before shipment. Screen and touch response are checked on assemblies, and batteries and charging accessories are tested before packing; inspection photos or videos of the packed goods can be provided on request.


Warehouse & Model Management
Products are organised by category, brand and model so that picking is accurate and order-matching errors are reduced. Stock is held across a broad SKU range covering all nine product lines, and incoming goods are sampled on arrival before they are put away.
Packing & Dispatch
Orders are checked, packed and prepared for express, air or sea shipment according to product type and delivery plan. Cartons are reinforced for export transport, and the shipping method and documents are confirmed on your invoice.


After-Sales Support
Our team handles warranty inquiries, product verification and issue assessment to provide timely support after delivery. Wholesale claims for defective, damaged or incorrect items are handled within 7 days of delivery with photos, and resolved by replacement or credit.
Certifications & Compliance
Certificates and compliance documents can be provided or obtained depending on the product and destination. CE, RoHS, UN38.3 and MSDS documentation is available for relevant items, and every shipment is issued with a commercial invoice, packing list and HS code information. Other certificates or declarations are confirmed per order on request.
Unless your invoice states DDP, the buyer is the importer of record. Certificates are issued for the items and destination confirmed on your order.
