FAQ
1. What certifications should buyers look for when choosing china fabric manufacturers?
Buyers should check for certifications like ISO 9001, OEKO-TEX, and GRS. These show that the factory meets quality and safety standards. Certifications help buyers trust that the company follows good practices and delivers safe, reliable fabrics.
2. How can buyers ensure fabric quality before placing a large order?
Buyers can ask for fabric samples or swatches before ordering. Many companies offer small samples for testing. Checking samples helps buyers see the color, texture, and quality. Some buyers also use third-party inspection services for extra peace of mind.
3. What is the typical minimum order quantity (MOQ) for fabric manufacturers in China?
Most china fabric manufacturers set MOQs between 500 and 1,000 meters per design. Some companies offer lower MOQs for special projects or new customers. Always ask the supplier about their minimum order size before starting.
4. How long does it take to receive fabric orders from China?
Production times usually range from 2 to 6 weeks, depending on the fabric type and order size. Shipping adds extra time. Air freight is faster but costs more, while sea freight takes longer but saves money.
5. Can buyers request custom colors or patterns from Chinese fabric factories?
Yes, many fabric manufacturers in China offer custom colors, prints, and finishes. Buyers should share clear design files or color samples. Factories often provide digital proofs or strike-offs for approval before full production begins.
