Fabric costing for Bangladesh apparel exporters is not only about comparing fabric price per kilogram. In real garment production, the final cost depends on GSM, usable width, shrinkage, cutting wastage, dyeing stability, and finishing performance.
A fabric that looks cheaper at the sourcing stage may become more expensive during bulk production if it causes higher consumption, lower marker efficiency, shade problems, reprocessing, or delivery delays. For factories, buying houses, and apparel exporters working with tight margins, understanding these cost factors is essential before confirming bulk fabric.
The goal is not always to choose the lowest fabric price. The real goal is to choose fabric that gives stable garment cost, smooth production, acceptable quality, and reliable delivery.
Why Price per KG Is Not Enough
Fabric is often quoted in USD/kg, especially for knitted fabrics. This makes supplier comparison simple, but garments are not sold by kg. They are sold by piece, dozen, or carton.
So the real costing question is not only “How much is the fabric per kg?” but “How much fabric cost is required for each finished garment?”
Two fabrics may have the same kg price but create different garment costs because of GSM, width, shrinkage, cutting loss, and process stability. This is why exporters should calculate fabric cost based on actual garment consumption, not only supplier quotation.
Key Fabric Factors That Affect Real Garment Cost
GSM
GSM directly affects fabric weight and garment consumption. If bulk GSM is higher than quoted, fabric cost per garment increases. If GSM is too low, the fabric may fail buyer expectations for handfeel, coverage, or structure.
Exporters should confirm quoted GSM, approved GSM, acceptable tolerance, and bulk testing method before production.
Usable Width
Factories should check usable cutting width, not only full fabric width. Selvedge, edge shade variation, holes, curling, or uneven edges can reduce the width available for marker planning.
Lower usable width can reduce marker efficiency and increase actual fabric consumption.
Shrinkage and Spirality
Shrinkage affects measurement stability and pattern adjustment. Spirality is especially important for knitted garments, as twisting after wash can cause visible garment defects.
Before bulk cutting, fabric should be tested according to the buyer’s wash method and care label requirement.
Cutting Wastage
Theoretical consumption is useful for quotation, but actual production depends on marker efficiency and cutting performance.
Stripe, check, directional fabric, placement print, brushed fabric, pile fabric, and defective rolls may all increase wastage. Costing should include realistic cutting loss based on fabric type and style.
Dyeing Stability
Dyeing consistency affects both quality and production cost. Shade variation, poor color fastness, or lab dip mismatch can lead to sorting, reprocessing, replacement, or buyer rejection.
For export orders, dyeing stability should be treated as a cost-control factor, not only a quality-control issue.
Finishing Performance
Finishing affects handfeel, appearance, shrinkage, spirality, pilling, and buyer approval. A lower fabric price may not be useful if extra finishing is needed to meet buyer expectations.
Fabric costing should include the full finishing requirement, not only greige or dyed fabric price.
Practical Fabric Costing Checklist
Before confirming fabric price, exporters should review the full cost picture. The following checklist can help reduce costing mistakes.
| Cost Factor | What to Check | Why It Matters |
|---|---|---|
| Price per KG | Supplier quotation and payment terms | Starting point of fabric cost |
| GSM | Quoted GSM vs actual GSM | Affects fabric weight and cost per garment |
| Width | Usable cutting width | Impacts marker efficiency |
| Shrinkage | Wash test and dimensional stability | Affects measurement and pattern adjustment |
| Spirality | Twisting after wash | Important for knitted garments |
| Wastage | Cutting loss and defect allowance | Changes actual fabric requirement |
| Shade | Roll-to-roll and lot-to-lot consistency | Reduces rejection and sorting cost |
| Fastness | Washing, rubbing, perspiration tests | Required for buyer approval |
| Finishing | Handfeel and appearance | Helps meet buyer expectations |
| Delivery | Lead time and production reliability | Protects shipment schedule |
How Exporters Can Reduce Fabric Cost Risk
To improve costing accuracy, factories and buying houses should build a more complete fabric evaluation process.
First, do not compare suppliers by kg price alone. Always calculate estimated fabric cost per garment.
Second, request technical details before confirming the order. GSM, width, shrinkage, color fastness, and finishing method should be clear from the beginning.
Third, test fabric before bulk production. Lab tests and wash tests are small costs compared with shipment delay or buyer rejection.
Fourth, communicate clearly with the cutting and production teams. Costing should not be separated from actual factory performance.
Finally, keep records from previous orders. Historical data on fabric consumption, wastage, shrinkage, and supplier performance can make future costing much more accurate.
Conclusion
For Bangladesh apparel exporters, fabric costing is more than negotiating the lowest price per kg. The real cost depends on how the fabric performs in production and how well it meets buyer expectations.
GSM, usable width, shrinkage, cutting wastage, dyeing stability, and finishing performance can all change the final garment cost. When these factors are ignored, a cheap fabric can become expensive very quickly.
A better approach is to evaluate fabric based on total cost, production reliability, and quality consistency. This helps exporters protect their margins, reduce buyer claims, and deliver orders with more confidence.
In today’s competitive apparel market, accurate fabric costing is not just a purchasing skill. It is a key part of successful garment export management.
