The Chinese tech giant announced a live launch event for the next series of smartphones will take place in Munich, Germany on the above date.
They tweeted: "Did you get it right? The countdown to #HuaweiMate30 starts now!
We're going full circle in Munich on 19.09.2019.

It's not yet known what operating system the phones will use.
Although Android were believed to power the Mate and Pro, after Donald Trump recently confirmed that the Huawei P30 Pro, P30 and Mate 20 Pro will get the Android Q update, Google recently stated that they won't be allowed to sell their services to Huawei following the trade war ban.
However, Huawei's Richard Yu insisted their new operating system, Harmony OS, isn't to replace Android.
Despite reports that the company created the system to be less reliant on Google's, the CEO stated they are still planning to work with Android.
He said: "The phones which are currently on sale can continue to use Google.
"That's why we have HarmonyOS for backup, in case we can't use Google in the future.
"Then you can use HarmonyOS, which will have better performance."
Yu also stated that they are hoping HarmonyOS can be used on smartphones.
He said: "It will be minor, minor work to transfer apps from the other ecosystems to HarmonyOS: transferring this ecosystem will be very easy to do."
On what the future holds after the company was added to a list of companies that US firms cannot trade with unless they have a license, amid the fears of national security concerns, and being knocked off the number one spot by Samsung, Yu said: "We are heading for the best products, the best innovations, the best user experience.
"That's what we are looking for and you can see that if this trade war had not happened then this year we had a very big possibility to be number one.
"So, this year maybe our market share cannot be number one but we consolidate the top two position. For us the market share is not the most important. The innovation, the user experience, customer satisfaction are the most important."
