Work overalls

When sourcing work overalls, prioritize fabric weight (GSM) and composition. For heavy-duty industrial use, a polycotton blend (65% polyester, 35% cotton) with a weight of 240-300 GSM is ideal for balancing durability and breathability. Ensure the fabric features triple-stitched seams at stress points (crotch, underarms) and reinforced knee pad pockets using high-abrasion materials like Cordura® to extend the garment's lifespan.

Compliance depends on the specific work environment. For general safety, look for ISO 13688:2013. If the overalls are for specialized fields, verify EN ISO 20471 for high-visibility, EN 1149 for anti-static properties, and EN ISO 11612 for flame retardancy. Always request OEKO-TEX® Standard 100 certification to ensure the textiles are free from harmful substances, especially for skin-contact garments.

Evaluate the utility features based on the end-user's needs. For mechanics, look for scratch-free designs (covered zippers and buttons) to protect vehicle paint. For construction, prioritize multi-functional tool pockets, hammer loops, and D-rings. Ensure the inclusion of elasticated waistbands and action backs to provide a full range of motion, which is critical for worker productivity and comfort.

Request a sample to perform a wash-and-wear test. Check for colorfastness (Grade 4 or higher) to ensure the dye doesn't bleed, and verify a shrinkage rate of less than 3% after multiple industrial washes. Inspect the zipper quality—reputable brands like YKK or SBS are preferred for heavy-duty applications to prevent hardware failure in the field.

Utilize third-party inspection services (such as SGS or Intertek) to conduct a During Production Check (DUPRO) and a Final Random Inspection (FRI). On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their manufacturing capabilities and quality management systems.

Negotiate based on Total Cost of Ownership (TCO) rather than just the unit price. For large volumes (e.g., >2,000 units), aim for a 15-25% discount compared to sample pricing. If you have a diverse size run, negotiate a flexible size breakdown within the Minimum Order Quantity (MOQ) to avoid excess inventory of less common sizes.

Always use secure payment channels provided by reputable sourcing platforms. Avoid direct wire transfers to private accounts. Utilize Escrow-based payment services where the funds are only released to the supplier after you have confirmed receipt and inspected the goods. Ensure all technical specifications and delivery timelines are clearly documented in a Proforma Invoice (PI) or a formal contract.

Confirm the HS Code (typically 6203.42 for cotton overalls) to accurately calculate import duties and taxes. For large shipments, FOB (Free On Board) is recommended as it allows the buyer to control freight costs and choose a preferred forwarder. Ensure the supplier provides a Certificate of Origin to potentially benefit from preferential tariff rates under bilateral trade agreements.
