Thank you Dreamworkz, already went to declare and claim the item by myself at Kompleks Kargo Udara Kedua Pulau Pinang.

Just to share with others, the custom officer who entertained me in the office is quite a decent guy and one DHL rep in the custom office helped me to correct the declaration form. The code is as Dreamworkz stated, 420292900 and tax is only 10% from item price+freight+insurance which came up to RM 62.++ from a total of RM626.++. No other fee is charged on me, no agent fee, no processing fee except those 10% tax.

Need to wait about 2 hour though before another DHL guy come to hand me a letter to claim a pass before entering the Cargo Complex. After paying the tax, went to claim entry pass and straight to DHL warehouse.
(note: Need to leave IC or license to get your pass. You'll claim it back once you exit the complex after letting the custom check your stuff at exit point.)

However one Custom Officer at the exit checkpoint is quite disrespectful. Without answering my greeting straight away ask me to open my package when I hand him my declaration form.
After showing him my bags, he talked loudly to the other officer like I'm not standing there hearing him, "Wei hang mau beg tak? Aku ambik kaler Biru, hang ambik kaler Hijau." His friend however doesn't  really sound like he want to entertain him saying he didn't want it, probably he's busy with the forms on his hand.

I showed him my tax reciept and let him check it. The other guy did inquire though whether the bags is expensive or not. The officer asked the brand, I just pointed at the tags, and then take my receipt back from him and gone straight away without saying anything. Most likely he mistook me as one of the runner boys they usually deal with since I went there by motorbike and wearing a jacket at that time.
