Inner apparel

Prioritize fabrics with high breathability and moisture-wicking properties. For premium lines, look for Long-staple Cotton, Modal, or Bamboo fiber which offer superior softness and antibacterial qualities. Ensure the Spandex (Elastane) content is between 5% and 15% to maintain shape retention after multiple washes. For seamless technology, verify the use of high-frequency bonding or ultrasonic welding to prevent skin irritation.

Products must adhere to OEKO-TEX® Standard 100, ensuring the garment is free from harmful chemicals like formaldehyde and Azo dyes. For the US market, compliance with CPSIA is required if targeting children's sizes. For the EU, ensure the supplier follows REACH regulations. Additionally, verify ISO 9001 for manufacturing consistency and BSCI or Sedex audits to ensure ethical labor practices.

Request lab reports for Colorfastness to perspiration and washing (minimum Grade 4). Conduct a stretch recovery test to ensure the waistband and fabric return to their original dimensions. For functional innerwear, check for Anti-pilling ratings (ISO 12945-2) and Bursting strength for knitted fabrics. It is highly recommended to source from verified manufacturers on Made-in-China.com who provide third-party inspection videos.

A top-tier supplier should provide Private Labeling (heat-transfer tags) to avoid itchy physical labels. They should offer CAD pattern making for size grading (XS to Plus Sizes) and support low-MOQ trial orders for custom colors (Pantone matching). Ensure they can handle specialized packaging like FSC-certified paper boxes or biodegradable polybags for eco-conscious branding.

Always implement a Pre-Shipment Inspection (PSI). Since inner apparel is a high-volume category, a 2.5 AQL (Acceptable Quality Limit) standard should be applied. Use Escrow payment services or Trade Assurance through platforms like Made-in-China.com to ensure funds are only released upon confirmation of goods meeting the agreed specifications.

Negotiate based on fabric weight (GSM) and yarn count. If the MOQ is too high, suggest using stock colors for the fabric while customizing the waistband or packaging to reduce initial investment. Ask for tiered pricing (e.g., 1k, 5k, 10k units) to understand the supplier's scalability and aim for a 10-15% discount on repeat bulk orders.

Inner apparel is lightweight but high-volume; use vacuum packaging to reduce volumetric weight and save up to 30% on air freight costs. For large sea freight orders, ensure the use of desiccant silica gel packs in every carton to prevent mold growth during long transit times through humid tropical zones.

Sign a formal Non-Disclosure Agreement (NDA) before sharing custom tech packs or designs. Ensure all payments are made to verified corporate bank accounts rather than personal accounts. Utilize the Audit Reports available on Made-in-China.com to verify the supplier's legal status and production capacity before signing a long-term contract.
