An oil tanker, also known as a petroleum tanker, is a merchant ship designed for the bulk transport of oil. There are two basic types of oil tankers: the crude tanker and the product tanker. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move petrochemicals from refineries to points near consuming markets.

The Agricultural Commissioner/Weights & Measures Department routinely conducts price verification inspections at retail locations to confirm that prices charged to consumers are the same as those posted or advertised. On a typical visit to a store, the inspector will select up to 15 items and then take them to the check stand for payment. When the items’ bar codes are scanned at the register, the price showing at the register must match what is posted on the shelf or advertised. If the prices do not match, the store will receive a notice of violation and the case may be turned over to the District Attorney’s Office or local city attorney for prosecution.
