Frequently Asked Questions

MOQ, customization, certification and lead time — what B2B buyers ask before ordering

What are the key specifications of the ZS Tianmao W558 egg cooker?

The ZS Tianmao W558 egg cooker holds 4 eggs, or 414 ml, runs on 110-120V at 350W and offers steamed, soft boiled, hard boiled and onsen tamago modes. The ceramic cup with a BPA-free PP housing weighs 1.04 kg. ZS Tianmao manufactures this model in its own factory.

What makes the W558 different from metal-plate egg cookers?

ZS Tianmao builds the W558 around a ceramic cup rather than a bare metal plate, so eggs lift out cleanly and the bowl wipes down. One-touch control adds auto shut-off and an audible alarm at the end. ZS Tianmao is the OEM and ODM supplier behind this design.

Can the W558 be customized with our logo, colour and packaging?

Yes. ZS Tianmao marks your logo on the W558 housing, matches white or a Pantone colour and builds colour boxes from 1,000 pcs. The lid, egg rack, ceramic cup and divider can be packed as your own set. ZS Tianmao is the factory of record for private-label orders.

Which certifications does the W558 hold, and can it be certified for our market?

The ZS Tianmao W558 egg cooker holds CE, CB and FCC approval, and ZS Tianmao can arrange ETL for North America and PSE for Japan. Certificates are issued to ZS Tianmao and verifiable by number. ZS Tianmao is the manufacturer named on every certificate.

What is the MOQ, sample lead time and bulk lead time for the W558?

The MOQ for the W558 is 1,000 pcs per colour. ZS Tianmao ships stock samples in 1 day and logo samples in 3-5 days, then completes bulk production in 30 days after sample approval. ZS Tianmao is the supplier that runs these lead times.

Which buyers is the W558 built for?

ZS Tianmao supplies the W558 to breakfast-appliance brands, Japanese onsen tamago sellers and gift retailers. The 4-egg ceramic cooker suits small kitchens, dormitories and hotel breakfast bars. ZS Tianmao is the manufacturer supplying these programmes.
