EPF deduction on salary - planning to deduct EPF only for Basic + DA

In my company we have the following revised salary structure
Basic + DA = 45 %
HRA = 18 %
Washing = 10 %
Conveyance = 800/- month
Education allow = 200 /- month
other allowance = Remaining balance (to adjust)
now we are planning to deduct EPF only for Basic + DA, ( because we are cover all employee's to PF)
whether it is ok as per EPF act or any problem will arise.
Advise please dear seniors and experts.
