Richie Richardson of the Emirates ICC Elite Panel of Match Referees imposed the sanction after the West Indies were ruled to be one over short of the target after time allowances were taken into consideration.
Captain Nicholas Pooran plead guilty to the offence and accepted the proposed sanction, so there was no need for a formal hearing.
On-field umpires Leslie Reifer and Nigel Duguid, third umpire Gregory Brathwaite and fourth umpire Patrick Gustard leveled the charge.
