What 3,000 m² and 50+ People Mean for Your Order
Every step — from cast PMMA sheet to finished, inspected mahjong set — stays under one roof.
Laser Engraving
Character and suit marks engraved into the tile face, then filled and sealed so the mark does not wear away with handling.
CNC Machining
Tile bodies machined to the approved size with a 0.3 mm chamfer on all four play edges; rack and pusher parts cut from the same released drawing.
Clear-Coat Seal
A clear top coat over the engraved or printed face, applied after the color check against your approved sample.
UV Printing
Full-color artwork printed directly on the tile face, Joker, or tile back.
4-Layer Lamination
Laminated tile construction for two-tone and backed designs, bonded without visible seams.
Assembly & Packing
Tile counting, rack and pusher fitting, insert placement, and case packout. Sets ship ready to play.

See our quality standards ›What Happens When Something Goes Wrong
100% visual inspection catches most issues before shipping. When something slips through:
You report the issue
Send photos and the affected quantity to inquiry@usmahjongcn.com so the review starts from evidence rather than a generic defect label.
We assess and take responsibility
We compare the evidence with your approved sample, the released drawing and the packing record, and state in writing what is confirmed.
We remake and reship
Affected pieces are remade to your approved specification and reshipped.
We fix the root cause
Each confirmed issue is traced back to the production step and the process is adjusted before the next run.
How we handle problems is what separates a vendor from a partner. More questions? See our FAQ.
Frequently Asked Questions
How long has USMJ been in business?
2012 is the year USMJ began manufacturing in Shenzhen. The operation runs from a 3,000 m² ISO 9001-certified facility with 50+ staff.
What certifications does USMJ hold?
3 compliance references are used across USMJ's factory and material documentation: ISO 9001 for quality management, plus SGS and RoHS material testing or compliance records where the order requires them. Every production set is inspected against the approved sample before shipment.
Does USMJ offer design services?
1 approved production drawing is the control point before sampling. USMJ provides design-for-manufacture review and production drawings, not full industrial design; send CAD, AI, PDF, a dimensioned sketch, or a reference tile with critical dimensions to start. Our mahjong case studies help identify the closest production route before the RFQ, and the mahjong custom tiles page lists the artwork, color and branding options.
