When to contact a Korean K-beauty shop: THE CAST hours in UTC
A conversion of the retailer’s published support hours for international shoppers.
THE CAST is a Korea-based online shop for Korean beauty products. International shoppers with a question can use its published support information to understand when its customer service operates. The hours below were checked on November 12, 2026 and may change.
Convert Korea time to UTC
THE CAST lists customer service on weekdays from 10:00 to 17:00 Korea Standard Time (KST, UTC+9), with a lunch break from 12:00 to 13:00. Subtracting nine hours gives 01:00–03:00 and 04:00–08:00 UTC on the corresponding Korean weekday.
Check the Korean calendar
The published information says customer service is closed on weekends and public holidays. Because the schedule follows Korea time, check the Korean date and holidays when converting to your location. Local daylight-saving changes can affect your local equivalent even though KST is UTC+9.
Prepare your inquiry
THE CAST lists My Page > 1:1 Inquiries for questions and replies. Identify the product and option, or use the official order support channel for an existing order. Check the current support page before contacting the shop; published hours do not guarantee an immediate reply.
