9006603_lUSA: The US Department of Commerce has initiated anti-dumping and anti-subsidy investigations into imports of R134a from China. 

The news follows a petition by Mexichem at the end of October accusing China of dumping cheap subsidised R134a onto the US market. A preliminary determination is expected around the end of next week.
