IPPI: Petroleum and chemical products are the major factors in the 12-month change - On a 12-month basis, the IPPI was up 0.6 percent in September, following decreases of 0.3 percent in July and August.
Prices for petroleum and coal products rose 36.1 percent from September 2004, up from August's increase of 27.9 percent. If petroleum and coal product prices had been excluded, the IPPI would have decreased 2.4 percent, rather than increasing 0.6 percent from a year ago.
Chemical products increased 5.5 percent, due to higher prices for organic industrial chemicals and synthetic resins. Prices were also higher than one year ago for rubber, leather and plastic fabricated products, tobacco products, non-metallic mineral products, as well as furniture and fixtures.
