Selling custom sportswear, gym activewear, or athletic gloves on Amazon FBA represents one of the fastest avenues to scale an e-commerce brand. However, Amazon fulfillment centers enforce rigorous inbound packaging and labeling requirements. Failure to comply leads to inventory refusal, re-packaging fees, or account suspension.
1. Inbound Packaging & Polybag Standards
Amazon requires every individual garment or pair of gloves to be safely enclosed:
- Suffocation Warning Labels: Any polybag with an opening of 5 inches or larger must display a prominent legal suffocation warning in multiple languages printed in legible 10pt+ bold type.
- Frosted Zipper Polybags: For private label brands, frosted matte EVA zipper bags provide an elevated unboxing experience compared to flimsy peel-and-stick clear bags, while meeting Amazon’s puncture-resistance guidelines.
- Ventilation Holes: Micro-perforated air vent holes allow air to escape when bags are compressed, reducing dimensional weight calculation surcharges.
2. FNSKU Barcode Application
Every size and color variant must carry a scannable FNSKU (Fulfillment Network Stock Keeping Unit) barcode:
- The FNSKU must be printed on the exterior of the polybag or hangtag, fully visible without opening the packaging.
- Code 128 barcode format must scan cleanly using industrial optical warehouse scanners.
- Sapiro Sports prints and applies your exact Amazon FNSKU barcode stickers directly during final factory inspection.
3. Master Carton Packing & Drop-Test Verification
Cartons shipped directly into Amazon fulfillment centers must satisfy strict physical criteria:
- Carton Weight Limit: Must not exceed 50 lbs (22.6 kg) per carton unless containing a single oversize unit.
- Carton Dimensions: No side may exceed 25 inches (63.5 cm) for standard inventory.
- Double-Wall Corrugated Boxes: We use heavy-duty 5-ply kraft corrugated cartons capable of passing standard ISTA-1A drop tests without product crushing during international airfreight.
