About Zhuhai Suny Technology Co., Ltd. - Electronic Shelf Label Supplier in China

Zhuhai Suny Technology Co., Ltd. is a China-based supplier located in Zhuhai, Guangdong Province, operating with an active catalogue of 5 products concentrated in a single category: electronic shelf labels (ESL) and digital shelf-edge signage. The supplier's listings span five distinct ESL display sizes, covering compact 2.13-inch and 2.9-inch tags through mid-range 4.2-inch units up to large-format 7.5-inch and 154-inch electronic labels, giving buyers a size ladder suited to retail shelf-edge, promotional signage and warehouse picking applications. ESL systems fall within the broader retail technology and electronic labelling industry, where Zhuhai sits within the Pearl River Delta manufacturing cluster that also covers Shenzhen, Dongguan and Guangzhou. This region hosts a large share of China's e-paper display module assembly, low-power wireless PCB production and lithium-polymer battery packaging lines. The supplier's product family maps to retail automation buyers who replace paper price tickets with battery-powered, wirelessly updated e-paper displays managed through a central gateway and cloud or on-premise software.

Product Range and Specialties of Zhuhai Suny Technology Co., Ltd.

Zhuhai Suny Technology Co., Ltd.'s catalogue covers five electronic shelf label form factors: a 2.13-inch ESL, a 2.9-inch ESL, a 4.2-inch ESL, a 7.5-inch ESL and a 154-inch ESL. E-paper ESL tags in these sizes are typically built around active-matrix electrophoretic (E Ink or compatible) displays with pixel densities in the 100-130 dpi range for the 2.13-inch and 2.9-inch formats, and lower-dpi matrix layouts for the larger 7.5-inch and 154-inch signage panels. Common display colours in this category are black/white, black/white/red and black/white/yellow tri-colour variants, with refresh times generally between 0.5 and 3 seconds per image update. Wireless connectivity in ESL systems of this type is typically delivered through 2.4 GHz proprietary RF protocols operating in the 2400-2483.5 MHz ISM band, with some product lines adding sub-GHz 433 MHz or 868/915 MHz options for longer-range warehouse use. Power is supplied by coin-cell lithium batteries (commonly CR2450, CR2477 or CR3032) for the smaller tags and by lithium-polymer rechargeable packs for the 7.5-inch and 154-inch formats, with typical battery life quoted at 5-7 years under 2-3 updates per day. Buyers in this category should expect to verify display resolution, operating temperature range (usually 0 to 40 degrees Celsius for retail, -10 to 50 degrees Celsius for industrial/cold-chain), IP rating of the housing, and the SDK/API documentation supplied for integration with the retailer's existing POS or ERP system.

Trade and Export Information - Zhuhai Suny Technology Co., Ltd.

Electronic shelf labels and digital signage panels are classified under HS code 8528 (monitors and projectors, including those capable of receiving and displaying data from automatic data processing machines) and HS code 8531 (electric sound or visual signalling apparatus, including indicator panels), with associated wireless gateways and base stations typically declared under HS code 8517 (telephone sets and apparatus for the transmission of data). China is the world's largest manufacturing base for ESL hardware, with the Pearl River Delta cluster in Guangdong accounting for a significant share of global e-paper module assembly and finished ESL unit shipments. Typical importing regions for ESL hardware include Western Europe (Germany, France, the Netherlands, the Nordics), North America, Japan, South Korea, Australia, and the Gulf states, where large supermarket chains, DIY retailers, pharmacies and warehouse operators are replacing paper labels. Industry-standard certifications commonly required for ESL exports into the EU include CE marking under the Radio Equipment Directive (RED, 2014/53/EU) covering the 2.4 GHz RF module, EMC Directive 2014/30/EU, and RoHS 2 (2011/65/EU) compliance for restricted substances; for North America, FCC Part 15 certification for unintentional radiators and intentional radiators is typically required, and for Japan, MIC (formerly TELEC) certification under the Radio Act. Buyers should also expect UN 38.3 test summaries for the lithium coin-cell or lithium-polymer batteries shipped with or inside the ESL units, and the relevant MSDS documentation for air and sea freight. Standard export packaging is inner foam-lined cartons with master cartons of 50-200 units depending on size, shipped on pallets via FCL 20 ft or 40 ft containers, with Incoterms typically quoted as FOB Shenzhen/Guangzhou or CIF destination port.

Sourcing from Zhuhai Suny Technology Co., Ltd. - Buyer Guidance

Sourcing electronic shelf labels from a China-based supplier requires verification of several technical and regulatory points before order commitment. Buyers should request the FCC ID and CE RED test report numbers for the specific model being ordered, confirm RoHS test reports against the EU 2011/65/EU list of restricted substances, and ask for the UN 38.3 battery transport test summary covering the lithium cells fitted inside each ESL. A pre-shipment inspection (PSI) covering display uniformity, pixel defect rate (typically defined per supplier as a maximum number of dead pixels per panel), battery voltage under load, and RF communication range against a reference gateway is standard practice in this category. Before placing volume orders, buyers should request working samples of each display size (2.13-inch, 2.9-inch, 4.2-inch, 7.5-inch and 154-inch) and confirm the SDK/API documentation, firmware update mechanism, and compatibility with the buyer's chosen ESL management software or POS middleware. Lead times for finished ESL units from Guangdong factories typically run 25-40 days after sample approval for orders in the 1,000-5,000 unit range, and 45-75 days for full container loads. MOQ varies by size, with the 154-inch large-format panels usually carrying the highest minimum order quantity and the longest lead time due to the lower-volume e-paper film supply chain. Confirming warranty terms (commonly 1-2 years on the display module and battery), RMA procedure, and the supplier's ability to supply replacement PCBs and battery holders is also advisable for long-term deployment.

What wireless protocol do these ESL systems use?

Most ESL systems of this type use a proprietary 2.4 GHz RF protocol operating in the 2400-2483.5 MHz ISM band, with some product lines offering sub-GHz 433 MHz or 868/915 MHz variants for longer-range warehouse deployments. Buyers should confirm the exact frequency band against the destination market's radio regulations.

Which certifications should I request before importing these ESLs into the EU or North America?

For the EU, request CE marking under the Radio Equipment Directive 2014/53/EU, the EMC Directive 2014/30/EU, and RoHS 2 (2011/65/EU) compliance documentation. For the US and Canada, FCC Part 15 certification is required for the RF module, and for Japan, MIC (formerly TELEC) certification under the Radio Act applies.

What battery and shipping documents are needed for the lithium cells inside the ESL units?

Each ESL contains either a coin-cell lithium battery (commonly CR2450, CR2477 or CR3032) or a lithium-polymer pack for the larger 7.5-inch and 154-inch formats. Buyers should request the UN 38.3 test summary and the MSDS for the specific battery model, both of which are required for air and sea freight under IATA and IMDG rules.

What is the typical MOQ and lead time for ESL orders from a Guangdong manufacturer?

MOQ varies by display size, with the 154-inch large-format panel usually requiring the highest minimum quantity due to lower-volume e-paper film supply. Typical lead times are 25-40 days for orders of 1,000-5,000 units after sample approval, and 45-75 days for full container loads.

How are ESL units typically packaged for export?
