The deadly coronavirus outbreak in China could start to disrupt India's production of smartphones if it continues to spread in February, industry executives said, as it could delay component shipments.
India is the world's biggest smartphone maker after China but is still largely dependent on China for supplies of parts such as cells, display panels, camera modules and printed circuit boards.
Taiwan's Foxconn and Wistron make iPhones in India for Apple, and Foxconn produces phones there for China's Xiaomi as well. Other smartphone makers in India include South Korea's Samsung and China's OnePlus.
So far smartphone makers in India have weathered the impact of the virus, which has already killed 170 people, partly because they had ramped up inventories of Chinese-made parts anyway to cover the Lunar New Year holiday period when China's factories close down.
"Those disruptions were already planned but if it (the virus' spread) gets prolonged then for March and April production we will have serious trouble," said S.N. Rai, the co-founder of homegrown smartphone maker Lava. "We're definitely worried about it."
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
Some components can be shipped in from markets such as South Korea, Vietnam or Taiwan, but smartphone makers will only make such purchases as a "last resort" as it would force companies to make changes including in design and software, Rai said.
China's OnePlus said its Indian operations could manage, in the short term at least.
"We are well covered because we have the entire production in India, we already have enough stock, and even going forward many of the components will anyway be coming directly from other markets," said Vikas Agarwal, the India head of OnePlus.
While Beijing has expressed confidence in defeating the "devil" virus, which is yet to be declared a global emergency by the World Health Organisation, major companies such as Alphabet Inc's Google and Sweden's IKEA have closed operations in China.
India's Tata Motors, which counts China as a major market for its luxury Jaguar Land Rover cars, said on Thursday it was worried about the coronavirus and warned that the outbreak could hit profits.
As several airlines suspend flights to China, the movement of technical staff from the country - such as on-site support executives, machine and automation specialists - will also be curtailed and that will hit India's smartphone sector, an executive at another foreign-owned smartphone maker, who did not wish to be named, said.
For now, the industry just hopes the outbreak can be contained within the next two weeks.
"If the problem persists beyond Feb. 10 then we have a real problem at hand," said Pankaj Mohindroo, head of the India Cellular & Electronics Association, an industry lobby group.
