regarding GST number for commission agents

Hello sir \ mam With due respect myself Bharat from Jodhpur .. i am a commission agent .. as per above messages .. GST number is required for above 20 lacs income on commission ... but as i read in google there is mandatory for Agent,broker, arthiya etc ..to have a GST number.. even if u have a income of rupees 1 bcoz government had ruled a compulsory 18% GST for any agent ... !!! GST on services provided by the commission agent will be applicable from the very beginning i.e. no threshold limit of Rs. 20 Lakh will be allowed in this case as compare to Rs. 10 lakh allowed in present tax laws. The recently introduced GST valuation rules specifically cover situations where goods are supplied by the Principal to an agent or vice versa. Such supplies are chargeable under GST. In simple words, any supply from Principal to an agent or otherwise will attract GST and thus either of the parties need to refer to these valuation rules to avoid a dispute with tax administrative authorities. So GST covers all the perspective widely as compare to present tax systems. so kindly make me acknowledge from this .. a big confusion for me
