For EV charger importers, CPO operators, Amazon sellers and energy solution partners, your sourcing model directly determines landed cost, import duty, time-to-market, certification workload and profit margin. Many Zopoise customers ask the same question: should they buy finished white-label wallboxes, SKD semi-knocked-down kits, or CKD components for local assembly?
There is no one-size-fits-all solution. Your best option depends on local regulations, in-house assembly capacity, order volume, branding plan and tariff structure. Based in Zhuzhou, Zopoise is a direct EV charger manufacturer with in-house SMT lines and a CNAS testing laboratory. We specialise in residential AC wallboxes and portable EV chargers, offering white-label, SKD and CKD cooperation models. Read on to understand each option and make your sourcing decision.
What is a White-Label EV Charger?
A white-label EV charger is a fully assembled and fully tested finished unit built on our proven hardware platform. We print your brand logo, customise the screen UI, and supply custom user manuals and packaging ready for resale. Our products hold ETL, FCC, TÜV and CE certifications, and we can issue secondary certificates for qualified partners.
Best for:
· D2C sellers, Amazon vendors and new market entrants with limited technical teams
· Small batch orders requiring fast launch without local assembly lines
· Partners focused on sales, branding and after-sales support rather than manufacturing
Pros:
· Short lead time: standard home charger models ship in 4–6 weeks
· No assembly required on your side; ready for sale upon arrival
· Zopoise provides complete test reports and compliance documents
· Supports mainstream home features including APP connectivity, scheduled charging and load balancing
Cons:
· Higher import duty in regions that classify finished EVSE as electronic goods
· Limited flexibility to adjust the BOM locally
· Higher shipping cost per unit compared to component kits
White-label AC wallbox OEM is our most popular entry package for customers in North America, Europe, India, Australia and the Middle East. It targets private residential charging and helps you launch your own charging brand quickly.
What is an SKD EV Charger Kit?
SKD stands for Semi-Knocked-Down. We pre-assemble core modules including the main control board, driver board, communication module and power circuit. Your team completes simple assembly: fit the enclosure, cable, charging connector and cover, then run basic function tests locally.
SKD sits between finished white-label units and full CKD kits. High-risk core electronics such as mainboards and power supplies are manufactured, aged and tested inside the Zopoise factory. You do not need to handle PCB assembly or firmware flashing.
Best for:
· Distributors and regional partners with a small local workshop
· Markets with preferential tariff rates for electrical components
· Existing white-label buyers looking to improve gross margin
Pros:
· Lower import duty than finished wallboxes in most countries
· Better container utilisation to reduce ocean freight cost
· Zopoise controls core circuit board quality and safety performance
· Moderate MOQ between white-label and CKD programmes
Cons:
· Requires basic assembly staff and simple testing tools
· Final inspection and packaging become your responsibility
Many of our EU and Southeast Asia customers switch to SKD after validating quality with white-label pilot orders. SKD home charger kits support localisation requirements while keeping technical risk under control, ideal for mass distribution of residential chargers.
What is a CKD EV Charger Kit?
CKD means Completely Knocked-Down. We supply separate individual parts: circuit boards, housing, cables, relays, RFID readers, displays, sealing parts, fasteners and more. All components are packed separately. Your team carries out full assembly, wiring, functional testing and ageing in your own facility.
CKD delivers the strongest tariff advantage but demands the highest technical capability. It is designed for established EV charger manufacturers, large energy groups and licensed assembly partners.
Best for:
· Large CPO operators and local manufacturers with certified assembly workshops
· Markets with high duties on finished goods and incentives for local assembly
· Long-term, high-volume residential charger projects
Pros:
· Optimised tariff classification as electrical components for lowest landed cost
· Full control over local supply chain and spare parts
· Lowest per-unit cost at high order volumes
Cons:
· Steep learning curve and assembly team training required
· Higher quality risk if local testing procedures are not properly managed
· Longer project ramp-up timeline
How Zopoise Supports Your Selected Sourcing Model
As a Zhuzhou-based home EV charger manufacturer, we keep core electronic production in-house. Our SMT workshop, CNAS lab and TÜV / UL witness test facility guarantee consistent quality for white-label, SKD and CKD projects:
1. Customisable functions: RFID & APP control, scheduled charging, residential load balancing, over-temperature protection for home use, plus OCPP1.6J for commercial pay-to-charge applications
2. Certification package: test reports, Declaration of Conformity (DoC), and secondary certificate support for white-label partners
3. Assembly documentation: BOM, wiring diagrams and test videos for SKD & CKD clients
4. Broad product portfolio: residential wallboxes, Mode 3 portable chargers and load-balancing variants
Important Sourcing Tip
Tariff rules and EV charger standards are updated frequently. Before committing to SKD or CKD, confirm how your local customs classify charger kits versus finished wallboxes. Working with a local customs and compliance consultant helps you calculate accurate total landed cost.
If you are unsure which model matches your target country, forecast volume and existing assembly capacity, contact us. Zopoise engineering and sales teams can prepare a custom white-label / SKD / CKD proposal and quotation for your home EV charger project.
