Payment to non resident indian

tds will be deducted at normal rates i.e.10% since you have got trc as well as pan 

Refer Article 14 of India UAE DTAA. If the web design services are provided remotely from UAE with no physical presence of self/employees in India (resulting in no Permanent Establishment in India), the amount paid is not taxable in India. In such a case, there is no TDS required to be deducted on that payment. A CA can certify in Form 15CB regarding this to allow remittance to UAE. No PE undertaking and Form 10F will need to be obtained from payee.

Specific fact evaluation is needed to arrive at a proper solution.
