Import B4 Compatible Toner — Buy in Bulk from Supplier in China

The B4 Compatible Toner from Guangzhou Shuangyi Sci-Technology Corporation is formulated for use in OCE TDS300 series printers and related wide-format systems. It delivers sharp, dense black output with a particle size distribution engineered for consistent electrostatic transfer. The toner is supplied as a dry powder in sealed cartridges or bulk containers, with a yield profile that matches or exceeds standard OEM page counts under ISO/IEC 19752 test conditions. Guangzhou Shuangyi operates from Huashi Sci-Technology Building in Tianhe District, Guangdong Province, a hub for southern China's electronics and printing consumables manufacturing cluster.

The toner base comprises polymerised styrene-acrylate resin with embedded carbon black pigment, magnetite charge-control agents, and surface-treated silica flow aids. Standard particle diameter ranges from 6 to 8 micrometres, with a median volume diameter (Dv50) of 7.0 micrometres typical for this class of monochrome toner. The formulation includes a wax component to provide oilless fusing at standard OCE fuser temperatures. The cartridge housing is moulded from recycled ABS with a separate waste-toner compartment, consistent with common circular-economy practices in the compatible consumables sector. Guangzhou Shuangyi specifies that the product meets OEM-equivalent density and fixative performance, though buyers should request batch-specific test reports.

Primary buyers include corporate reprographics departments, architectural and engineering print shops, and educational institutions operating mid-volume wide-format fleets. The toner suits technical drawings, CAD renderings, and text-heavy documentation on uncoated and lightly coated papers. Trade terms are not specified in the source data, so importers should confirm Incoterms, minimum order quantities, and cartridge shelf-life guarantees directly with Guangzhou Shuangyi. The supplier's response rate is currently logged at zero percent, which suggests enquiry turnaround may be slow, buyers may benefit from following up through multiple channels.

The listing presents Guangzhou Shuangyi as a source of B4 compatible toner for OCE wide-format printers, emphasising page yield, installation ease, and environmental credentials through recyclable materials. The source does not state ISO 9001, ISO 14001, or any other certification held by this supplier, nor does it list specific export markets, reference clients, or years in operation.
