Qatar's shift to a hybrid substrate for this series was a deliberate infrastructure decision — polymer notes had proven problematic in Gulf climates due to heat-related stacking issues, so the hybrid option offered improved durability over cotton paper without the full drawbacks of pure polymer. De La Rue's Safeguard substrate, used across several Gulf state reissues in this period, sits behind that choice.

The TBB#220 reference places this within Qatar Central Bank's most recent circulating family, replacing an older cotton-paper series that had been in use since the mid-2000s.
