| Fiber Composition | Common commercial constructions include cotton with approximately 3%–5% elastane, or polyester blends with elastane. | Match the fiber blend to the end use. Cotton-rich pique generally emphasizes comfort and breathability, while polyester-rich blends typically improve moisture management, durability, and dimensional stability. | High | Fiber-content test report and signed product specification |
| Fabric Weight | Approximately 180–240 g/m² is a common range for lightweight to midweight polo shirts. | Confirm the target GSM after washing, because finishing and laundering can affect the final weight. Select lighter weights for warm climates and heavier weights for structured uniforms or cooler markets. | High | Pre-production fabric swatch and GSM test result |
| Stretch and Recovery | The fabric should provide comfortable crosswise stretch and recover its shape after repeated extension and washing. | Ask for test conditions, stretch percentage, recovery percentage, and the number of wash cycles used. Evaluate the collar, placket, side seams, and body separately. | High | Stretch-recovery report and wash-test samples |
| Dimensional Stability | A commonly requested tolerance for finished knit garments is about ±3% length or width change after care testing, subject to the agreed specification. | Define the washing method, water temperature, drying method, and measurement points before bulk production. Check shrinkage in both the fabric and finished garment. | High | Dimensional-stability test report and approved size chart |
| Colorfastness | For mainstream export apparel, buyers commonly request at least Grade 4 for color change and crocking, with stricter requirements for dark or high-visibility colors. | Test washing, perspiration, water, light, and dry or wet rubbing. Confirm that the testing standard and rating scale are stated clearly on the report. | High | Independent colorfastness laboratory report |
| Pilling Resistance | A minimum of Grade 3–4 after an agreed number of rubs or washes is a practical commercial target for many polo programs. | Use the buyer's required method, such as Martindale or another recognized textile test method. Inspect high-friction areas including the underarm, side body, and seat. | Medium–High | Pilling report and post-wash inspection sample |
| Construction and Workmanship | Consistent stitch density, secure seam ends, even topstitching, balanced plackets, and a stable rib collar are expected for export-quality polos. | Review seam strength, skipped stitches, puckering, button attachment, bartacks, label placement, and tolerance control. Ask for an approved workmanship standard with photographs. | High | Pre-production sample, workmanship checklist, and inspection report |
| Sizing and Grading | Size grading should follow the buyer's measurement chart, with tolerances defined separately for chest, body length, shoulder, sleeve, and collar measurements. | Require a size-set sample before bulk cutting. Confirm whether measurements are taken relaxed or stretched, particularly for the chest, rib collar, and sleeve opening. | High | Size-set sample and approved measurement specification |
| Compliance and Restricted Substances | The supplier should demonstrate control of applicable chemical, product-safety, labor, and environmental requirements for the destination market. | Check compliance with destination-country rules, including fiber labeling, care labeling, restricted-substance requirements, and any buyer-specific code of conduct. Do not rely on certificates alone; verify scope and validity. | High | Current audit documents, test reports, and traceable transaction records |
| Minimum Order Quantity | MOQ varies by fabric color, yarn, trim, and production line. Custom colors and custom fabrics generally require higher quantities than stock materials. | Request separate MOQs for each color, size range, fabric construction, and decoration method. Confirm whether small trial orders carry development or setup charges. | Medium–High | Written quotation with MOQ and setup-fee schedule |
| Production Lead Time | A typical export program may require roughly 45–90 days from confirmed materials and approved samples, depending on fabric availability and order complexity. | Separate fabric booking, lab-dip, sample, cutting, sewing, finishing, inspection, and dispatch timelines. Obtain a critical-path schedule rather than a single delivery date. | High | Milestone schedule and written delivery commitment |
| Quality-Control System | A robust process includes incoming-material inspection, inline checks, final inspection, measurement control, and defect classification. | Confirm the inspection level, acceptable quality limit agreed in the purchase contract, inspection timing, corrective-action process, and retention of production records. | High | Quality manual, inspection forms, and independent final-inspection option |
| Packaging and Export Readiness | Packaging should protect stretch garments from moisture, abrasion, compression, color transfer, and incorrect assortment during international transport. | Specify folding method, carton dimensions, polybag requirements, carton markings, barcodes, assortment ratio, and packaging materials. Confirm export documentation capability. | Medium | Packing specification, carton test details, and sample shipping documents |
| Total Landed Cost | The relevant comparison is product cost plus development, testing, packaging, freight, duties, inspection, payment, and potential quality-loss costs. | Compare suppliers using the same fabric weight, composition, testing scope, Incoterm, packaging standard, and payment terms. The lowest unit price is not always the lowest landed cost. | High | Comparable quotation and landed-cost worksheet |
