Indonesia has allowed the supply of granite, which it disrupted in January, to be exported to Singapore.

"Since early March, we have seen a steady resumption of granite supply from Indonesia," National Development Minister Khaw Boon Wan said in a blog post on Thursday.

"We have always required all importers to have a small supply from distant regional sources, even during normal times ... Supplies from other sources are coming in readily."

He also said that no one had applied to draw down from the national granite stockpile in March and the Government will accordingly "suspend the application for granite stockpile release" from March 14 onwards.

The Government will replenish its granite stockpile, he said, adding that the Building and Construction Authority will "continue to promote the use of steel, drywalls and recycled concrete aggregates, so as to reduce our reliance on imports of natural aggregates."

Granite is a key component in concrete.

The Government activated the release of granite supplies from the national stockpile at Pulau Punggol Timor in early February, after the sudden Indonesian supply disruption caused construction delays.

It also encouraged granite importers to ramp up supply from distant sources.
