Common Questions About Quality Control
How quickly will you respond to my inquiry?
We typically respond to all inquiries within 2 business hours during our operating hours (Monday–Friday, 8 AM – 6 PM HKT). For urgent requests submitted outside of business hours, our team aims to reply by the start of the next working day.
Can I get a same-day inspection quote?
Yes. If you submit your request with complete product and factory details before noon HKT, we can usually provide a quote the same day. For standard requests, quotes are delivered within 24 hours.
What information do I need to provide for a quote?
To provide an accurate quote, we need: the type of inspection or audit required, product details (type, quantity, specifications), factory name and address, your preferred inspection date, and any specific standards or requirements your products must meet.
Do you offer rush inspection services?
Yes, we offer rush inspections that can be arranged within 24 hours in most major manufacturing regions. Rush services are subject to inspector availability and may carry a surcharge. Contact us directly for urgent scheduling.
