The production of larger iPad tablet is facing delays.
It is not clear whether the delay could impact the sales plan of Apple in a big way.
The delay is because Apple suppliers have delayed the production of a larger iPad to early next year, the Wall Street Journal reported.
The suppliers had planned to start producing the larger screen tablet in mass volume beginning in December, but have been struggling to produce enough new iPhones to keep up with demand.
Foxconn Technology, which assembles iPhones and iPads, has 200,000 workers in China already putting together new iPhones and making items such as metal casings.
Apple is expected to launch the new iPads at an event on October 16.
Asian suppliers expect Apple’s larger tablet to have a 12.9-inch liquid-crystal-display screen with a resolution similar to the iPad Air launched in October last year.
Data research firm IDC said in August that it expected tablet sales to slow globally in 2014.
The company said it sold more than 10 million of its new iPhones in the first weekend they were available in September.
