Cotton panties

You should prioritize Combed Cotton or Pima Cotton with a weight of 140-180 GSM for the best balance of breathability and durability. Ensure the fabric blend includes 5-8% Spandex (Elastane) to maintain shape retention and elasticity after multiple washes. For the inner crotch lining, strictly require 100% unbleached cotton to ensure hygiene and skin-friendliness.

The most critical certification is OEKO-TEX® Standard 100, which guarantees the product is free from harmful chemicals. For organic claims, verify GOTS (Global Organic Textile Standard). If exporting to the US, ensure compliance with CPSIA (especially for children's sizes), and for the EU, ensure adherence to REACH regulations regarding azo dyes and heavy metals.

Request details on the Stitch Density, which should ideally be 10-12 stitches per inch to prevent seam unraveling. Check for Flatlock Seams to minimize skin irritation. You should also ask for Colorfastness Test Reports (Grade 4 or higher) to ensure dyes do not bleed during washing, and Shrinkage Control within a ±3% range.

Cotton panties are primarily targeted at the Daily Comfort and Maternity segments due to their moisture-wicking properties. Other high-growth areas include Period Panties (with leak-proof layers) and Seamless Cotton-blend versions for professional wear. Understanding your niche allows you to specify the correct waistband tension and leg opening finish (e.g., lace trim vs. folded edge).

Always use Secure Payment Terms such as Letters of Credit (L/C) or payment systems provided by reputable platforms like Made-in-China.com that offer escrow-like protection. Never pay 100% upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry norm for protecting buyer interests.

Negotiate based on Total Cost of Ownership (TCO) rather than just unit price. Ask for Tiered Pricing (e.g., 5,000 units vs. 20,000 units) and inquire if the supplier can offer Free Packaging Customization for larger volumes. Mentioning long-term partnership potential can often secure a 5-10% discount on initial quotes.

Since underwear is lightweight but high-volume, use Vacuum Packaging to reduce the cubic volume and save on Sea Freight costs. For the US and Europe, clarify the Incoterms (FOB is recommended for better control over shipping lines). Ensure the supplier provides a Certificate of Origin to help you benefit from potential Preferential Tariff Rates under trade agreements.

Implement a Pre-Shipment Inspection (PSI) by a third-party agency (like SGS or Intertek). Define a Golden Sample that both parties sign; this sample serves as the legal benchmark for quality. Include a Penalty Clause in the purchase contract for deviations in material composition or size specifications exceeding AQL 2.5 standards.
