Clean room garment

Clean room garments must be made from lint-free, non-shedding synthetic fibers, typically 100% continuous filament polyester. For ESD (Electrostatic Discharge) protection, the fabric must incorporate conductive carbon-core yarns woven in a grid or stripe pattern (usually 5mm spacing). The material should also offer high filtration efficiency to prevent human particles from contaminating the environment while maintaining breathability for wearer comfort.

Selection depends on the ISO 14644-1 standard. For ISO 4-5 (Class 10-100) environments, a full coverall (bunny suit) with integrated hoods and boots is mandatory. For ISO 7-8 (Class 10,000-100,000), lab coats or two-piece suits may suffice. Ensure the supplier provides Particle Shedding Test reports (Helmke Drum Test) to verify the garment meets the specific cleanliness class of your facility.

Prioritize suppliers who comply with IEST-RP-CC003.4 for garment considerations in cleanrooms. For safety and quality management, look for ISO 9001:2015 certification. If the garments are used in medical or pharmaceutical sectors, ensure they meet CE marking requirements and EN 1149 for antistatic properties. Always request a Certificate of Conformance (CoC) with every batch.

Look for tunnelized elastic in wrists and ankles to prevent particle leakage. Seams should be bound or felled (not raw) to eliminate fraying. Zippers should be made of synthetic materials and covered by a protective flap. Avoid pockets or hook-and-loop fasteners (Velcro) in high-grade clean rooms as they harbor particles; instead, use stainless steel snaps or high-quality plastic studs.

If your facility requires sterile garments (e.g., in biotech or pharmacy), ensure the material is Gamma-compatible. The fabric must withstand repeated sterilization cycles (Autoclaving or Gamma Irradiation) without losing its structural integrity or antistatic properties. Ask the supplier for the maximum number of validated wash/sterilization cycles the garment can endure before it must be decommissioned.

Request a pre-shipment inspection (PSI) by a third-party agency to verify fabric weight, ESD resistivity, and stitching quality. Utilize Made-in-China.com's Secured Trading services to ensure payment is only released after the goods pass quality verification. Always order a production sample before committing to a bulk order to test the fit and fabric feel.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate based on durability (number of washes); a slightly more expensive garment that lasts 100 washes is more cost-effective than a cheap one that fails after 30. Discuss MOQ flexibility for different sizes (S-4XL) to ensure you don't overstock unpopular sizes while maintaining a volume-based discount on the total order.

Clean room garments are sensitive to environmental contamination. Ensure the contract specifies double-vacuum packaging in a clean environment before shipping. Use HS Code 6210.10 (Garments made of felt or nonwovens) or 6211.33 (Industrial coveralls) to check for specific import duties and anti-dumping regulations in your country. For urgent needs, Air Freight is recommended to avoid the humidity risks associated with long-term Sea Freight.

Verify the supplier's Business License and Export Qualification on the Made-in-China.com platform. Look for 'Audited Suppliers' who have undergone on-site inspections by independent bodies like SGS or Bureau Veritas. Use Escrow-based payment methods to protect your capital against non-delivery or sub-standard products.
