CHINA has approved a new standard for compound rubber that reduces the amount of natural rubber allowed in the formula, a move that is expected hurt major producers in Thailand and Malaysia, analysts and traders said.

    Compound rubber, which includes small amounts of powdered carbon, has become popular in China as it can be imported tariff-free, compared to a 1,500 yuan (US$242) per ton tariff for natural rubber.

    The rule change by the world’s top rubber consumer, which was first proposed in August, will cap the natural rubber content in compound rubber at 88 percent, down from 95-99.5 percent previously.

    This will make the compound less stable and much less attractive to tire manufacturers, likely killing off demand for the product, traders and analysts said.

    The new standard will be implemented July 1, said a notice published on the Standardization Administration’s website.

    “From July, the use of compound rubber will dramatically decline,” said Quan Shuwen, senior analyst at Dongwu Futures.

    Producers are expected to ship large volumes of compound rubber into China ahead of the rule change but it is unclear whether they will produce the product after July.

    The remainder of the compound must be made up of carbon black, a fine powder that is difficult for rubber producers to handle without installing special equipment.

    Traders said the move would benefit Chinese rubber producers, such as Hainan Rubber Industry Group, although tire companies would still need to source large amounts of natural rubber from overseas to meet demand.

    China imported 2.3 million tons of natural rubber and 1.35 million tons of synthetic material in the first 11 months of 2014.
