FBA Prep for Oversize Items: What You Need to Know

<p>Oversize items on Amazon mean bigger profits — but also bigger headaches if prep goes wrong. Here's what you need to know.</p><h2>What Counts as Oversize?</h2><p>Amazon defines oversize as any single unit exceeding: 16x12x8 inches or weighing more than 3.5 lbs. There are four sub-categories: small, large, standard, and special oversize.</p><h2>Prep Requirements Are Stricter</h2><ul><li><strong>Extra bubble wrap</strong> — corners and edges must have 2+ inches of cushioning</li><li><strong>Heavy-duty boxes</strong> — no flimsy packaging. Amazon's automated systems drop boxes</li><li><strong>Label placement</strong> — FNSKU on all sides? Not required, but smart. If one label gets damaged during transit, we apply extras</li></ul><h2>Cost Considerations</h2><p>Oversize prep at SNS Prep Center: a flat per-unit rate (up to 7 lbs and 24 inches). Heavier items — custom quote.</p><p>Compare that to the alternative — shipping an incorrectly prepped oversize item to Amazon, having it rejected, and paying return shipping on a 30-lb box. The math is simple.</p><p><a href=/prices>See our full oversize pricing</a>.</p>
