TIC companies have typically maintained pricing power due to the low number of suppliers compared with the
large number of clients, who tend to place greater importance on reputation, brand and quality of service, and are
fairly indifferent on pricing, particularly where TIC costs are relatively insignificant. It is estimated that external
testing services for sectors other than the resources industry costs approximately 0.5–1.0% of total revenues, and
is generally lower for the minerals and oil and gas sectors.
