Key consumer tech products have so far mostly escaped the heat of the ongoing trade war. But if U.S. President Donald Trump makes good on his threat to impose tariffs on the full range of Chinese imports into his country, it could hit that sector hard, experts said.

Rajiv Biswas, Asia Pacific chief economist at IHS Markit, said that products such as mobile phones and smart watches and other wearable devices could be targeted in the next round, while ANZ Greater China Chief Economist Raymond Yeung pointed to mobile phones as well as other consumer goods.

"If the US Administration imposes a third tranche of tariff measures on a further USD267 billion of Chinese exports, this will significantly ramp up the economic shock waves to Chinese exporters," Biswas told CNBC in an email.

Apple said earlier this month that the tariffs could affect the Apple Watch and AirPods as well as adapters and chargers for a host of products. But according to the latest list of tariffs that kicked in this week, they have been spared so far.

Autos is another sector that could continue to be targeted, said Carol Liao, a senior China economist at J.P. Morgan.

According to ANZ, key items at stake include consumer goods, which form 45 percent of China's exports to the U.S., and autos, which is at 4 percent.

The next round of tariffs, according to Biswas, would likely hit large multinational companies producing goods in China for export, as well as Chinese small and medium-sized enterprises that are part of the global supply chain.

Automakers are already feeling the heat, with Trump slapping a 25 percent levy on China-made autos, in July. Ford scrapped a plan to sell its new Chinese-made Focus Active crossover model in the U.S., while Volvo moved the production of its XC60 crossover from China to Sweden. General Motors, meanwhile, sought an exemption for its Buick Envision model, also made in China.
