Every fabric inspection ends with the same question: is this roll first quality or second quality? The answer depends on which grading system the buyer uses and how consistently the inspector applies the point rules. Textile mills shipping fabric to multiple buyers must manage grade expectations across the 4-point system preferred by US apparel brands, the 10-point system used by military and industrial fabric buyers, and a growing number of buyer-specific grading variations that combine elements of both. The difference between a first-quality grade of A and a second-quality grade of B can be 15 to 40 cents per yard in selling price. Mills that rely on human inspectors for grading face 15 to 25 percent disagreement rates between inspectors grading the same roll, and up to 40 percent disagreement between the mill grade and the buyer audit grade on the same shipment. AI-powered fabric grading systems apply point rules consistently across every roll, every inspector, and every shift, and produce grades that match buyer audit results with 96 percent or higher agreement. Mills using AI grading reduce grade disputes with buyers by 70 to 85 percent and capture an additional 3 to 5 percent of production as first-quality fabric that human inspectors had incorrectly downgraded.
Automate Fabric Grading with AI-Powered Inspection
iFactory AI grading supports the 4-point system, 10-point system, and custom buyer grading standards. Consistent scoring across every roll, every shift. Deployed in 7 to 14 days.
4-Point versus 10-Point Grading Systems
Both grading systems assign penalty points based on defect size, but they differ in the maximum points per defect, the defect length thresholds, and the acceptable point limits per 100 square yards. The cards below compare the two systems side by side.
4-Point System
Preferred by US apparel and retail buyers10-Point System
Used by military, industrial, and technical fabric buyersPoint Accumulation Example
The table below shows how the same fabric roll with 6 defects would be scored under both the 4-point and 10-point systems. The final grade depends on the total points per 100 square yards after all defects are scored.
| Defect | Size | 4-Pt Pts | 10-Pt Pts |
|---|---|---|---|
| Warp break | 4 in | 2 | 2 |
| Weft slub | 2 in | 1 | 2 |
| Hole | 0.5 mm | 4 | 4 |
| Oil stain | 7 in | 3 | 10 |
| Warp float | 1.5 in | 1 | 2 |
| Weft bar | 12 in | 4 | 10 |
Grade Conversion Table
Total points per 100 square yards determine the fabric grade. The table below shows the standard grade boundaries for the 4-point system, the corresponding quality level, and the typical price impact for each grade.
| Grade | Points / 100 yd2 | Quality Level | Typical Price Impact | Buyer Acceptance |
|---|---|---|---|---|
| A | 0 – 20 | First quality | Full price | Accepted by all buyers |
| B | 21 – 40 | First quality (close-out) | 5–10% discount | Accepted by most buyers with allowance |
| C | 41 – 60 | Second quality | 15–30% discount | Limited buyer acceptance |
| D | 61 – 80 | Third quality | 40–50% discount | Close-out or salvage channels |
| Reject | 81+ | Waste | Salvage value only | Not shippable |
