Mar 30, 2026 253 views
Starting in April 2026, we’re making updates to Multi-Channel Fulfillment (MCF) and Buy with Prime, including how orders are packaged and shipped in the United States, to help reduce packaging waste and align MCF and Buy with Prime more closely with existing Fulfillment by Amazon (FBA) packaging practices.
Updates include the following:
- Packing slips will no longer be included by default.
- Items already certified for the Ships in Product Packaging (SIPP) program on Amazon.com will ship without an Amazon overbox by default.
- Eligible MCF and Buy with Prime SIPP shipments will receive a discount.
These updates will roll out gradually from April 1-30, 2026. SIPP discounts will begin applying as soon as your SIPP-certified items start shipping.
Check whether your ASINs are eligible or certified for SIPP in Seller Central . Starting in April, these settings will apply to FBA, MCF, and Buy with Prime orders.
If you would like to opt out of SIPP or include a packing slip with all MCF and Buy with Prime orders, go to Multi-Channel Fulfillment Settings . These settings will take effect in April, but you can update them now and change them at any time.
If you use the Fulfillment Outbound API to send MCF orders, you can configure overbox and packing slip settings at the order level.
If no action is taken by the time these updates take effect, MCF and Buy with Prime orders will ship without packing slips, and SIPP-certified items will begin shipping without Amazon overboxes.
To learn more, go to Ships in Product Packaging (SIPP) and review the MCF SIPP help page .
