Finding a Clothing Supplier for Amazon FBA: The Complete Seller's Guide

Amazon FBA is one of the most attractive channels for private label clothing sellers. You handle product and brand; Amazon handles storage, picking, packing, and shipping to millions of customers. But the clothing category has specific complexities — sizing, returns, and saturation — that require a thoughtful sourcing strategy.

This guide covers everything an Amazon clothing seller needs to know about finding and working with a private label apparel manufacturer.

Why Private Label Clothing Wins on Amazon

The generic reselling problem: If you buy wholesale branded garments and list them on Amazon, you're competing on price in a race to the bottom. Anyone can undercut you.

Private label solves this: Your own branded product has a unique ASIN. No one can win your Buy Box. Your review accumulates to you. Your brand equity grows with every sale.

The category opportunity: Clothing and accessories is Amazon's largest category by number of listings and continues to grow. But most listings are commodity products. A well-photographed, clearly differentiated private label product with consistent quality and good reviews can dominate a niche.

What Amazon Clothing Sellers Actually Need from a Supplier

Compliance with Amazon FBA prep requirements

Amazon is strict about how inventory arrives at their warehouses. A supplier who understands these requirements saves you from costly errors:

• FNSKU barcode labels on every unit (either the manufacturer applies them, or you do before sending to Amazon)
• Polybag requirements — clothing must be in a sealed polybag with a suffocation warning if the opening is larger than 5 inches
• Suffocation warning — "Warning: To avoid danger of suffocation, keep this plastic bag away from babies and children."
• Carton labels — must include shipment ID, box dimensions, and weight
• Box size limits — standard boxes up to 25" × 25" × 25"

At Potato Apparel, we're experienced with FBA prep. We handle FNSKU labelling, polybag sealing, suffocation warnings, and carton labelling directly at our factory before shipment. Just provide your FBA shipment details during the order process.

Consistency across reorders

Amazon ranking is built on sales velocity, reviews, and conversion. If your product quality fluctuates between reorders, your review score suffers. You need a manufacturer who uses the same fabrics, specs, and processes on reorder #10 as they did on reorder #1.

Ability to scale

Most Amazon clothing businesses grow fast once they find a winning product. Your supplier needs to be able to scale production with you — from 100 units to 500 to 2,000 without compromising quality or lead time.

Private label branding

Amazon sellers need their own brand on the garment for Brand Registry and A+ content eligibility. Confirm your supplier does:

• Woven neck label with your brand
• Custom hang tag
• Care label with country of origin
• Branded polybag if required

Sizing, Fit, and Returns: The Biggest Challenges

Clothing has the highest return rate of any Amazon category (20–40% vs. 5–8% for electronics). Most returns are size-related. Here's how to minimise them:

Create a clear, accurate size chart — Based on measurements, not just S/M/L. Amazon customers in the US measure in inches; provide both.

Request a full size set sample — Before approving bulk production, get one unit in every size. Measure every piece against your spec. Size grading errors are common and devastating to reviews.

Lean toward generous sizing — American and European customers have complained about Chinese sizing being too small for decades. If your product is described as "relaxed fit," make sure it genuinely is.

Add clear fit notes in your listing — "Runs true to size," "Size up if between sizes," etc. Customers appreciate clarity.

Consider selling sets — One-size-fits-most products (oversized tees, robes, loungewear) have dramatically lower return rates than fitted items.

Finding a Supplier: What to Look For

Low MOQ for testing

Amazon is a testing environment. Until you know a product converts and sustains rank, you shouldn't order 500 units. Look for suppliers with 50–100 piece MOQ so you can test without over-investing.

Fast sampling

Amazon trends move fast. If a keyword is gaining momentum, you need to be able to source, sample, and launch within 60–90 days. Suppliers with 7–10 day sample turnaround are preferable.

Quality documentation

Returns kill Amazon businesses. Invest in suppliers who provide AQL inspection reports, pre-production samples, and measurement verification. Every defective unit that reaches a customer is a 1-star review waiting to happen.

In-stock fabrics

Suppliers with inventory of common fabrics (basic cotton jersey, standard fleece) can move faster on your reorders. Suppliers who source fabric for every order add 2–3 weeks to production time.

References from other Amazon sellers

The best validation is a reference from another seller who's been reordering from the same factory for 12+ months. Ask in seller communities.

The Amazon FBA Apparel Sourcing Process

Step 1: Product research
Use tools like Helium 10 or Jungle Scout to identify niches with demand but limited quality competition. Look for keywords with 3,000+ monthly searches and fewer than 50 competing ASINs with 100+ reviews.

Step 2: Brief your manufacturer
Send 3–5 reference products you want to replicate or improve upon. Request pricing at your target quantity (start with 100 units).

Step 3: Sample
Order 2–3 samples at different price/quality points. Wash them, try them on, photograph them. Compare against your reference products.

Step 4: Launch preparation
While bulk production runs (20–30 days), create your listing, take professional photos (hire a photographer with a model), and set up your A+ content if Brand Registered.

Step 5: FBA shipment creation
Create your FBA shipment in Seller Central before the goods ship. Provide the shipment ID to your manufacturer for carton labelling.

Step 6: Launch and review gathering
Soft launch with PPC to gather initial reviews. Use Vine if you're Brand Registered.

Step 7: Reorder planning
Reorder when you have 60–90 days of inventory remaining (accounting for 30–45 day manufacturing and shipping time).

Cost Calculation: Full Landed Cost to FBA

Most Amazon sellers focus on manufacturing cost and miss the full picture. Your true cost is:

Manufacturing cost: $8–$18 per unit (varies by garment and quantity)
Branding/packaging: $0.50–$2.00 per unit
QC inspection: $0.10–$0.30 per unit
Shipping to FBA (sea): $1.50–$3.00 per unit
US import duty (apparel): $1.50–$4.00 per unit
FBA storage + fulfillment: $3.50–$6.00 per unit (depending on size tier)
Amazon referral fee (15%): Varies by price

Example for a $39.99 hoodie:

• Manufacturing: $16.00
• Branding + packaging: $1.00
• Shipping + duties: $3.50
• FBA fees: $5.50
• Amazon referral fee: $6.00
• Total cost: $32.00
• Profit per unit: $7.99 (20% margin)

This improves significantly at higher quantities and as you grow reviews (enabling higher prices).
