Hydrocarbon Oils Strategy

Registered Dealers in Controlled Oils (RDCO): preparation

Take some time to read the trader’s folder and understand how the trader operates. Look on Departmental Trader Register (DTR) (using the trader’s RDCO number) and Electronic Folder to check on the trader’s performance in other regimes. Lack of compliance in one scheme may indicate an inherent compliance problem with the trader. This compliance can be in the areas of both submission of returns and payment of money due.

Check RDCO Monitor, which may reveal errors on the returns prior to the visit.
