Chinese Sourcing and the Yuan. Harrison Equipment of Denver, Colorado, purchases all of its hydraulic tubing from manufacturers in mainland China. The company has recently completed a corporate-wide initiative in six sigma/lean manufacturing. Completed oil field hydraulic system costs were reduced 3.9% over a one-year period, from $875,000 to $840,875. The company is now worried that all of the hydraulic tubing that goes into the systems (making up 21% of their total costs) will be hit by the potential revaluation of the Chinese yuan-if some in Washington get their way. How would a 11.8% revaluation of the yuan against the dollar impact total system costs? Chinese Sourcing and the Yuan.
