India is said to be considering new duties on the import of a key smartphone component in a bid to promote domestic manufacturing in the world\u2019s fastest-growing smartphone market. India\u2019s Ministry of Electronics and Information Technology has mooted a proposal to impose a 10 percent duty on imports of populated printed circuit boards, Reuters reports, citing two unidentified government officials. A PCB is a bed for key components such as processors, memory and wireless chip sets that are the heart of an electronic device. The duty could be imposed in days if the finance ministry clears the recommendation, making populated PCB imports expensive and forcing companies to assemble components locally, according to the report. Bloomberg News could not reach senior officials at the electronics & information technology, commerce or finance ministries for comment on Sunday. Prime Minister Narendra Modi has been pushing companies to establish more manufacturing operations through his \u201cMake in India\u201d program. Higher duties may push Apple Inc. to expand its manufacturing and assembly capabilities in the country and give it an edge over its rivals such as Samsung Electronics Co. and Xiaomi Corp. In February, India\u2019s government raised custom duties on imported mobile phones to boost local production of components. Apple has been seeking to expand its presence in India and has negotiated with the government for lower tariffs on certain components.
