OEM Thermal Underwear Sourcing Q&A

Get answers to the most common questions regarding materials, customization options, and wholesale supply chain logistics.

What is the minimum order quantity (MOQ) for custom OEM thermal underwear?

Our standard MOQ for custom dyed and styled thermal underwear sets typically starts at 1,000 units per color/style. However, for standard stock colors or fabric compositions, we can accommodate smaller trial runs starting at 500 units. Contact our sourcing team for details.

Which fabric weights (GSM) are recommended for different temperature zones?

For mild cold environments (5°C to 15°C), we recommend lightweight fabrics of 150-180 GSM (modal/polyester blends). For colder temperatures (-5°C to 5°C), midweight fabrics around 200-250 GSM are optimal. For extreme sub-zero weather, heavy thermal fleece materials spanning 280-350 GSM provide the best heat retention.

How does Nanjing VEIL ensure compliance with global environmental standards?

We work exclusively with certified raw material suppliers who carry OEKO-TEX Standard 100 and Global Recycled Standard (GRS) certifications. We perform strict chemical and dye safety testing to ensure our garments are safe for retail export and skin-contact use globally.

What is your typical turnaround time from design approval to delivery?

Sampling usually takes 7-10 working days. Once the pre-production sample (PPS) is approved and the deposit is settled, bulk production takes roughly 35-45 days, depending on the order volume and fabric customization requirements. Freight times depend on the destination country and chosen transit method.

Can you support custom stitching like flatlock seams and compression panels?

Yes, we specialize in high-end athletic base layers using 4-needle 6-thread flatlock stitching, which creates clean, flat seams that prevent chafing. We also integrate localized elastane panels for ergonomic muscle compression and zoned thermal performance.
