JAKARTA, July 16 (Xinhua) -- Indonesia logged a steep shipment of products offshore in June year-over-year as some commodities prices hike lingered, the national statistics bureau said Monday.

The bureau announced that export ratcheted up 11.47 percent to 13 billion U.S. dollars in June from a year ago.

Head of the bureau Kecuk Suhariyanto said some prices of commodities shot higher in the global market which in part drove up value of Indonesia's export during the month.

"From May to June, there were some prices of commodities crept up, including the prices of coal, nickel and aluminum," he said at the bureau headquarters.

The cumulative of export by in the first half also set a 10.03 percent growth to 88.02 billion U.S. dollars on yearly basis, Suhariyanto noted.

The Southeast Asia's biggest economy is the world's largest exporter and producer of crude palm oil and thermal coal, and the world's biggest exporter of rubber and cocoa, as well as home to the world's second largest copper mine.

For import, the official revealed that it drifted up 12.66 percent to 11.26 billion U.S. dollars in June.

The huge differential of export and import in June led to a trade surplus of 1.74 billion U.S. dollars, he cited.

China, followed by Japan and Thailand is the largest supplier of imported non-oil and gas products into Indonesia in the first six months with values respectively 20.57 billion U.S. dollars, 8.63 billion U.S. dollars and 5.32 billion U.S. dollars, Suhariyanto noted.

Export along with consumption and investment contributed the most to the country's gross domestic product growth.

The government has scrambled to stave off the termination of special low import tariffs applied by the U.S. government on Indonesia's products by way of lobbying the U.S. government.
