NS

A Non-Sortable (NS) item is any product that exceeds Amazon’s default size or weight thresholds for standard sortation at sortable fulfillment centers. These items require special handling, are stored in non-sortable FCs, and often have different prep and shipping requirements.

Amazon considers an item NONSORT if:

• It exceeds any of these dimensions:
  • 18 inches x 14 inches x 8 inches (45.5 cm x 34.0 cm x 26.5 cm)
• Or weighs more than:
  • 20 lbs (9.1 kg)

Key characteristics of NONSORT items:

• Sent to non-sortable fulfillment centers (e.g., LAX9, SMF3)
• May involve manual sorting, storage, and shipping
• Prone to higher fulfillment costs and longer processing times
• Require non-standard prep, like corner protection or palletization
• Often tied to Heavy Bulky (HB) classification for logistics

Why NONSORT status matters:

• Impacts FBA fees and shipping timelines
• Affects warehouse slotting and inventory turn rates
• Must be labeled and packaged properly to avoid receiving issues
• Sellers should review size/weight during NIS (New Item Setup) to avoid misclassification

💡 Example: A 22-pound air purifier measuring 20" x 15" x 12" is automatically classified as NONSORT and routed to a non-sortable FC for FBA.

In short:
NS / NONSORT means a product is too large or heavy for Amazon’s standard fulfillment systems - requiring special handling at non-sortable centers, often with higher fees and longer delivery timelines.
