Frequently Asked Questions

Key information on custom branding MOQ, material selection, international shipping, and quality assurance.

What is the minimum order quantity (MOQ) for custom logo badminton rackets?
For in-stock factory standard models, we support low MOQ starting from just 1 pc (ready stock) to easily test your local market; for full custom branding including water decals, custom colorways, and bespoke packaging, we support OEM mass production starting from 300 pairs.
Do the rackets come pre-strung and ready to play?
Yes! All wholesale orders include factory pre-stringing with durable multi-filament nylon strings at standard factory tension (18-22 lbs). All models arrive completely ready for immediate retail display or play.
How do I choose between Steel Two-Piece, Steel Jointless, and Carbon-Aluminum models?
Steel Two-Piece models offer unmatched impact resistance at entry-level wholesale costs, ideal for schools and outdoor leisure. Steel Jointless models provide smoother aerodynamics and enhanced durability for club practice. Carbon-Aluminum composite models deliver lightweight flexibility and higher string tension (up to 26 lbs) for intermediate club players and custom brand projects. Detailed tiered factory quotes are provided upon RFQ request.
