SIPP is Ship in Product Packaging. The name is accurate: when a product is enrolled in SIPP, Amazon ships it to customers directly in the product's own retail packaging, without adding any additional protective materials or an outer shipping box.
For some products, this is fine. A rigid plastic container with clean geometry that can survive the stresses of Amazon's fulfillment process without damage — SIPP makes sense. The problem is that Amazon makes the SIPP enrollment decision unilaterally, based on its own packaging assessment criteria, and it does not notify you when it enrolls your ASINs.
For food products, especially fragile ones — anything with glass packaging, brittle seals, easily crushed cartons, or pressure-sensitive closures — SIPP enrollment is consistently the wrong call. Amazon's own fulfillment process is rough on packages. Products move through sorting systems, get stacked in totes, and land on conveyor belts. Retail packaging designed to sit on a store shelf is not designed for that.
What happens when SIPP meets fragile food packaging
Damage rates go up. The most common failure modes are crushed corners, broken seals, and product arriving with visible deformation that makes it look used or compromised even when the food inside is fine. Customers who receive damaged-looking packages have two responses: they return the product, or they leave a review about the packaging. Often both.
Returns increase your return rate, which Amazon tracks at the ASIN level. Reviews about damaged packaging suppress conversion rate by adding social proof of a negative experience. Both of these degrade your IDQ score — Inventory Data Quality — which is Amazon's measure of how well your listing and product perform against their standards.
Here is the sequence the brand sees: customer complaint volume goes up, returns go up, one-star reviews start mentioning packaging, conversion rate drops. The team's diagnosis is usually "we have a quality problem" or "customers don't like the product." Both of those explanations lead to the wrong response — reformulation, new photography, listing copy rewrites.
None of that fixes the problem. The problem is that Amazon changed how it fulfills the product without telling you and the fulfillment method is not compatible with the packaging.
Who gets hit by this
Any food or CPG brand with packaging that was not explicitly designed for direct-to-consumer shipping stress. Specifically:
Glass jars and bottles. Glass is inherently fragile, and SIPP provides no cushioning against impact. A glass jar that survives normal shelf handling has no protection against dropping in a fulfillment center sort system.
Flexible pouches with zipper closures. The closure mechanism can fail under pressure, and damaged closures look like tampered product even when they are structurally intact.
Products in cartons with printed finishes. High-gloss packaging that shows every dent and scuff arrives looking visibly damaged even if the product inside is fine. Customers will return it.
Multi-unit sets with multiple loose components. SIPP means those components have no outer packaging to prevent them from shifting against each other in transit.
Fresh and refrigerated products are a separate category with different fulfillment rules, but the principle is the same: Amazon's default program assumptions were not built around your specific packaging requirements.
How to check your enrollment status
Log into Seller Central. Go to Inventory, then Manage FBA Inventory. For each ASIN, there is a column for fulfillment information. You can also check under the FBA settings for each product where packaging configuration is shown.
The faster method is to go to Seller Central's FBA program preferences and check the Ships in Product Packaging section under Packaging Support. This shows your current SIPP enrollment status at the account and ASIN level. If products are enrolled that you did not intentionally enroll, that is the issue.
How to disenroll
Disenrollment requests are submitted through Seller Central. Navigate to the ASIN's inventory page and look for the fulfillment program settings. For SIPP specifically, there is an option to request standard packaging, which means Amazon adds an outer box or poly-bag before shipping.
The disenrollment processes within a few days to a few weeks depending on Amazon's review queue. In some cases, Amazon will ask for packaging certification documentation — test results showing that the product packaging does not meet their own direct-ship standards. This is the route to permanent disenrollment: if your packaging is certified as not meeting ISTA 3E or SIOC standards (Amazon's direct-shipping packaging tests), Amazon cannot re-enroll it without a new submission.
Once disenrollment processes, units already held in FBA will be fulfilled with standard Amazon packaging going forward. You do not need to recall and re-ship inventory.
The reason this matters beyond damage rates
SIPP enrollment suppresses IDQ, which suppresses discoverability. Below 90% IDQ, Amazon begins restricting certain traffic channels to your listings. A brand can be losing organic search visibility and attributing the decline to algorithmic changes, seasonal shifts, or competitor activity — when the actual root cause is a packaging setting that was changed without notification six weeks ago.
Fix the SIPP enrollment. Review IDQ. Then reassess the organic traffic situation. The order matters.
