Interstate purchase of taxable goods from registered dealer without charging IGST.

I have made interstate purchase of silk Saree. The supplier is registered under GST. However he has not charged IGST. Silk saree is subject to 5 % GST. Also RCM does not apply in case of interstate purchase.
What is my the tax implication?
