Wholesale T-Shirt Supplier — Bulk Custom T-Shirts for Retailers and Brand Distributors
SDF Clothing is a wholesale t-shirt supplier in Bangladesh providing bulk custom t-shirts for retailers, distributors, and buying houses in USA, UK, Australia, Canada, and EU markets. FOB Dhaka pricing from 500 pieces minimum with guaranteed GSM consistency, controlled shrinkage rates, and batch-to-batch color fastness. All fabric weights available: 140-220 GSM cotton, polyester blends, organic cotton, and recycled materials.
GSM Consistency — Wholesale T-Shirt Fabric Weight Standards
GSM (grams per square meter) consistency is critical for wholesale t-shirt buyers because fabric weight directly impacts perceived quality, hand feel, and customer satisfaction. Retail customers expect consistent weight across all t-shirts in a product line — variation between batches causes customer complaints and returns. SDF guarantees GSM consistency within ±5% of specified weight across all wholesale orders. This tolerance is tighter than many suppliers who allow ±10% variation, and our actual performance typically exceeds this guarantee with variation under ±3%.
We achieve GSM consistency through standardized fabric sourcing from the same mills for each fabric specification, retained fabric samples for every order to match future production, and in-house GSM testing before cutting. Every wholesale shipment includes a fabric testing report documenting actual GSM measurements from multiple points across the fabric roll. If GSM falls outside tolerance, the fabric is rejected before production begins. This strict quality control prevents weight variation from reaching retail shelves.
| Fabric Type | Target GSM | Tolerance | Testing Method | Documentation |
|---|---|---|---|---|
| Lightweight Cotton | 140-160 GSM | ±5% | ASTM D3776 | Fabric test report |
| Midweight Cotton | 160-180 GSM | ±5% | ASTM D3776 | Fabric test report |
| Heavyweight Cotton | 200-220 GSM | ±5% | ASTM D3776 | Fabric test report |
| Polyester Blend | 150-180 GSM | ±5% | ASTM D3776 | Fabric test report |
| Tri-Blend | 140-160 GSM | ±5% | ASTM D3776 | Fabric test report |
| Organic Cotton (GOTS) | 160-180 GSM | ±5% | ASTM D3776 | Fabric test report + GOTS cert |
Shrinkage Rates — Dimensional Stability Standards
Shrinkage control is essential for wholesale t-shirts because dimensional stability affects fit and sizing consistency after customer washing. Excessive shrinkage causes t-shirts to become too small, leading to returns and negative reviews. SDF controls shrinkage through pre-shrunk fabric options, optimized cotton sourcing, and controlled washing during production. Our shrinkage rates are maximum 5% lengthwise and 3% widthwise after washing, compliant with major retailer standards including Walmart, Target, and Amazon requirements.
We test shrinkage according to AATCC 135 standards (dimensional changes after laundering) and include shrinkage test reports with every wholesale shipment. For buyers requiring tighter shrinkage control, we offer pre-shrunk fabric options that undergo additional compacting during fabric production, reducing shrinkage to maximum 3% lengthwise and 2% widthwise. Pre-shrunk fabric adds approximately 3-5% to fabric cost but significantly reduces customer returns due to sizing issues.
| Fabric Type | Lengthwise Shrinkage | Widthwise Shrinkage | Test Standard | Pre-Shrunk Option |
|---|---|---|---|---|
| Standard Cotton | Maximum 5% | Maximum 3% | AATCC 135 | Available (+3-5% cost) |
| Combed Ring Spun | Maximum 4% | Maximum 3% | AATCC 135 | Available (+3-5% cost) |
| Heavyweight Cotton | Maximum 5% | Maximum 3% | AATCC 135 | Available (+3-5% cost) |
| Polyester Blend | Maximum 3% | Maximum 2% | AATCC 135 | Standard (no extra cost) |
| Tri-Blend | Maximum 4% | Maximum 3% | AATCC 135 | Available (+3-5% cost) |
| Organic Cotton | Maximum 5% | Maximum 3% | AATCC 135 | Available (+3-5% cost) |
Color Fastness — Batch-to-Batch Color Consistency
Color fastness and batch-to-batch color consistency are critical for wholesale t-shirt buyers because color variation between orders damages brand perception and causes customer returns. SDF maintains color consistency through standardized dye houses with long-term partnerships, retained color lab dips for every order to match future production, and spectrophotometer color measurement for objective color matching. We test for wash fastness (AATCC 61), rub fastness (AATCC 8), and light fastness (AATCC 16) on every production batch.
Color lab dips are physical fabric samples showing the exact color achieved in dyeing. We retain lab dips for every wholesale order and use them as reference when re-dyeing fabric for re-orders. This ensures that color on re-orders matches color on initial orders within acceptable tolerances. For buyers requiring precise color matching, we offer spectrophotometer color measurement with ΔE values reported, enabling objective color evaluation and acceptance criteria. Color fastness reports are included with every shipment, documenting test results against industry standards.
Wholesale T-Shirt Pricing — Volume Tiers
Wholesale t-shirt pricing follows volume-based tier structures with FOB Bangladesh pricing. Unit costs decrease as order volume increases due to fabric sourcing efficiency, production setup optimization, and decoration economies of scale. Pricing below reflects basic cotton t-shirts (160-180 GSM) with single-color screen print. Pricing varies by fabric weight, decoration complexity, and order volume. We provide detailed quotes with itemized pricing for all wholesale inquiries.
| Volume | Price/Unit | Total FOB (1000 pcs) | Discount vs Standard | Best For |

Getting Started with SDF Clothing — What to Expect
Starting a new manufacturing relationship requires trust, clear communication, and a structured process. SDF Clothing has worked with hundreds of brands across the USA, UK, Australia, and Europe, and we've refined our onboarding process to make it as simple and transparent as possible for new clients.
The first step is always a design brief or tech pack submission. You don't need a finished tech pack to get started — even a rough sketch, a reference garment, or a detailed description is enough for us to provide a ballpark quote and confirm whether your project is a good fit for our factory. From there, we move to formal costing, which includes fabric sourcing, trim selection, and lead time confirmation.
Sampling is the most important phase of any manufacturing project. We produce a pre-production sample for your approval before any bulk fabric is cut. This sample lets you verify fit, construction, fabric quality, and color accuracy before committing to full production. Most clients approve samples within two rounds of revisions. We never proceed to bulk without your written approval.
Bulk production follows a structured quality control process. Our QC team conducts in-line checks during production and a final AQL inspection before packing. You receive a pre-shipment inspection report with photographs and measurements before we release your order for shipping. If anything falls outside the agreed specifications, we address it before the goods leave our factory.
Shipping from Bangladesh to the USA, UK, or Australia takes between 22 and 35 days by sea freight. We prepare all export documentation including commercial invoice, packing list, certificate of origin, and bill of lading. For EU shipments, we include the necessary documentation to support duty-free entry under the GSP scheme. Air freight is available for urgent orders and samples.
What Brands Say About Working with SDF Clothing
Our clients value three things above everything else: reliability, communication, and quality consistency. We respond to all enquiries within one business day. We provide weekly production updates during bulk manufacturing. And we back every shipment with our quality guarantee — if a garment doesn't meet the agreed specifications, we make it right.
Whether you're launching your first clothing brand with 300 pieces or scaling an established label with thousands of units per season, SDF Clothing provides the same level of attention and professionalism. Our minimum order quantity of 300 pieces reflects our commitment to supporting brands at every stage of growth, not just large buyers with the leverage to demand low prices.
