Is photography equipment import tax free?

Hi, I would like to seek the advice from experienced ebay users in miri.

Will buying any photography equipment inccur import tax? There are those who mentioned that anything below RM500 will be import tax free? (Correct me if i am wrong). Is it safe to buy from ebay because I can see most of the sellers are using standard international flat rate posting method which is not trackable?

Please help!I am so confused
