The stock slid as much as 9.8% to RM2.03 in the local bourse here today to the lowest level since May last year.

Trading volume was almost 17 times the 20-day average for this time of day. Shares of other glove makers Top Glove Corp and Hartalega Holdings Bhd also declined.

The US CBP said today that it issued the withhold release order against Supermax and units based on information that “reasonably indicates” the use of forced labour.

The company makes up to 24 billion pieces of gloves annually, meeting about 12% of the world demand for gloves.

Malaysia’s palm oil and rubber glove producers have grappled with intense scrutiny from US authorities over poor labour practices.

The CBP previously banned imports from FGV Holdings Bhd and Sime Darby Plantation Bhd and last month allowed Top Glove Corp, the world’s largest rubber glover maker, to resume shipments to the US after a year-long ban on its products.

The CBP identified 10 of the 11 International Labour Organization’s indicators of forced labour while investigating Supermax, the agency said in a statement.
