Compression stockings

When selecting compression stockings, the most critical factor is the compression level (measured in mmHg). Common grades include Class I (15-20 mmHg) for daily wear, Class II (20-30 mmHg) for medical recovery, and Class III (30-40 mmHg) for severe conditions. You must also evaluate the material composition, typically a blend of Nylon and Spandex (Lycra); a higher Spandex percentage usually ensures better elasticity and shape retention. Additionally, check for graduated compression technology, where pressure is highest at the ankle and decreases up the leg to effectively promote blood flow.

As these are often classified as medical devices, they must meet strict regulatory requirements. For the US market, FDA registration is essential. For the EU, products must have CE marking and comply with Medical Device Regulation (MDR). Furthermore, ensure the textiles are OEKO-TEX Standard 100 certified to guarantee they are free from harmful substances, and look for manufacturers with ISO 13485 certification, which specifically covers quality management systems for medical devices.

Request a pressure distribution test report from the supplier to confirm the graduated pressure is accurate. You should also evaluate the denier (D) count, which indicates thread thickness; higher denier often correlates with better opacity and durability. Perform a wash-and-wear test on samples to check for pilling resistance and to ensure the stockings do not lose their compression strength after 50+ wash cycles.

A top-tier supplier should offer custom sizing charts to fit specific regional demographics and private labeling for branding. Technical customizations include open-toe vs. closed-toe designs, silicone anti-slip top bands, and the integration of functional yarns like antibacterial copper infusion or moisture-wicking bamboo fibers. Ensure the supplier can provide CAD mockups and physical samples for approval before mass production.

The primary risk is non-compliance with local health authorities, which can lead to customs seizures. Always verify the supplier's export qualifications on Made-in-China.com and request valid, verifiable certificates. Another risk is batch inconsistency; mitigate this by hiring a third-party inspection service (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) focusing on tension strength and pressure accuracy.

Negotiate based on Total Cost of Ownership (TCO) rather than just unit price. For initial orders, aim for a flexible MOQ (e.g., 500-1000 pairs per size/color) to test the market. Request tiered pricing where the unit cost drops by 10-20% as volume increases. If you are a long-term buyer, negotiate for free replacement of defective units (usually a 1-3% defect allowance is standard in textiles).

Compression stockings are sensitive to moisture and extreme heat, which can degrade the elastic fibers. Ensure the supplier uses moisture-proof PE bags for individual packaging and double-walled corrugated master cartons. For shipping to the US or Europe, compare FOB (Free On Board) and DDP (Delivered Duty Paid) terms; DDP is often preferred for e-commerce sellers as it simplifies customs clearance and import duties.

Always use secure payment methods provided by reputable platforms. On Made-in-China.com, utilize the Secured Trading Service to ensure your payment is only released to the supplier once you confirm receipt and inspection of the goods. Avoid direct wire transfers to private accounts; always pay to the verified company bank account listed on the platform.
