Top sources in the DRI said that some time back the Hyderabad unit of the agency had registered a case with regard to certain duty evasion by a firm which had trading links with the Chinese entity.
As part of its investigations into the actions of a particular firm, the Delhi zonal unit of DRI had recently carried out a raid at the Gurgaon office of Huawei.
Sources said that the investigating agency had seized at least three laptops along with certain documents from the firm which have now been sent to Hyderabad for further investigation.
"The case is registered against a different company and not against Huawei. But during the investigation, name of Huawei came up and hence we had to check certain transactions of the firm. The laptops and documents were seized in this regard," a senior DRI official said.
Officials of Huawei could not be reached immediately for comments.
Huawei has been operating in India since 1998 when it set up its first R&D centre here followed by its marketing and sales office in 2002.
The company claims to have been a preferred vendor of leading service providers like Reliance Communications, Vodafone-Essar, Bharti Airtel, BSNL and Idea.
