Revised Amazon FBA Labeling Policy: 5 Key Changes for Sellers in 2026

Attention, all cross-border e-commerce sellers! Amazon FBA product labeling policies have recently undergone major updates, with multiple key changes directly affecting your warehousing efficiency and operational costs. We have sorted out the core key points to help you avoid potential risks.

Change 1: Standardization of FNSKU label sizes

New regulation requirement: Starting from March 2026, the FNSKU label size for all FBA products shall be unified at 30mm×20mm with a tolerance not exceeding ±2mm. The previously permitted 40mm×20mm specification will no longer be accepted.

Scope of Impact: Sellers of small items such as apparel, home goods, and electronic accessories need to pay close attention.

Response Suggestions: Immediately check the existing label templates and adjust printing settings. It is recommended to use a thermal transfer printer to ensure the barcode clarity is above 300dpi.

Change 2: Outer carton labels must be pasted on both sides

New regulation requirement: Each outer carton must be affixed with identical FBA outer box labels on two opposite sides. Shipments with labels pasted on only one side may be rejected or subject to additional handling fees (approximately $5 per carton).

Implementation Time: Strictly implemented from April 15, 2026

Response Suggestions: Optimize the packaging process, train warehouse staff to develop the habit of double-sided labeling. Automatic labeling machines can be purchased to improve efficiency.

Change 3: Strengthened labeling of expired goods

New regulation requirement: For products with a shelf life (such as cosmetics, food, and health supplements), "EXP + date" must be clearly marked on the front of the package with a font height of no less than 5mm. Marking only on the outer carton will no longer be compliant.

High-risk categories: Beauty & Personal Care, Maternity & Baby Products, Pet Food.

Response Recommendations: Communicate with suppliers to upgrade packaging, plan inventory turnover in advance, and avoid the overstocking of near-expiry products.

Change 4: Marking Requirements for Mixed Cargo Items

New regulation requirement: When multiple SKUs are contained in the same outer carton, the outer carton label must be affixed with the "Mixed SKU" mark, and the quantity of each SKU shall be listed on the packing list.

Penalty Measures: Mixed goods without marking may be required to be returned in full cartons, with double freight charges incurred.

Response Suggestions: Try to avoid mixed packaging and shipment. If mixed packaging is unavoidable, use the "Packing Slip Template" in the Amazon backend to generate compliant documents.

Change 5: Electronic labeling for dangerous goods

New regulation requirements: For dangerous goods including lithium batteries, liquids, powders and other hazardous items, in addition to physical labels, sellers must upload an electronic dangerous goods declaration form via the seller backend 48 hours prior to shipment.

Newly added categories: Bluetooth earphones, power banks, liquid skin care products, powdered supplements.

Response Suggestions: Complete the dangerous goods review in advance, establish the submission process for electronic forms, and avoid shipment detention.

Practical Suggestions

1. Conduct an immediate self-inspection: log in to the seller backend and check if there are non-compliant labels on shipments created in the last 30 days;

2. Update the SOP: Incorporate the new policies into the warehouse operation manual and organize relevant training;

3. Small-batch test: First ship 5-10 cartons to test the new label format, and arrange mass shipment after confirmation of no errors.

4. Attention Notice: Subscribe to Amazon seller news, as policies may continue to be fine-tuned.

Labeling may seem trivial, but it directly impacts warehousing efficiency and operational costs. According to seller feedback, shipment delays caused by labeling issues increased by an average of 3 to 5 days in 2025, with additional costs of approximately $200 per shipment.

Policy changes are the new normal, and adapting in advance allows you to take the initiative. If you encounter any issues in the labeling process, feel free to scan the code for consultation.
