Pococo galaxy star projector

Hi everyone, I just ordered the pococo galaxy star projector yesterday, paid on their official website using PayPal and everything was fine and well, got a confirmation email immediately with my order number and up to that point everything standard about an online purchase. This morning I got this email from their support team:

Hello, Thank you for your order and for choosing POCOCO. To proceed with the shipment to <redacted>, we kindly need your Tax Identification Number as required by customs regulations. This information is necessary to ensure a smooth delivery process and to avoid delays or issues with clearance. Please be assured that your personal information will be kept strictly confidential and used only for shipping purposes. We appreciate your understanding and cooperation, and we look forward to your reply.

Anyone know if it's legit? standard practice? I've never gotten an email like this when ordering stuff even from websites that aren't Amazon\Aliexpress etc. I just don't like sending the ID number "freely" on a regular email like that.

The email came from this address: POCOCO Customer Care Team [email protected]

Thanks in advance!
