SIPP and SIOC: Designing a Box for Amazon Tests

What SIPP and SIOC mean for a box project

SIPP is Amazon's Fulfillment by Amazon program that enables eligible products to ship in their own custom packaging without Amazon-added material. Customers can still choose additional Amazon packaging at checkout. SIOC means ships in own container. Consult Amazon's current enrollment instructions, packaging guidelines, applicable testing procedures, and seller terms for program requirements. Treat this article as a planning framework for design and evidence, not as a substitute for those instructions or your converter's production specifications.

Amazon's SIPP page describes eligibility review, product grouping, and testing steps. It also notes that enrollment is free, while updating packaging may carry costs, and that products with liquids or sharp items may need third-party lab testing. Those statements frame the work: you are designing a shipper, a product holder, and a printable brand surface at the same time.

Confirm eligibility and grouping first

Before you draw a box, confirm that the product is eligible and has a buyable offer fulfilled through FBA. Then decide how you will group products for testing, because a sensible group can reduce the number of certifications you submit.

• Check current eligibility and program terms in your seller account.
• Group by size, weight, material, packaging, and product-to-packaging ratio.
• Test the largest or heaviest product in each group.
• Confirm whether self-test is allowed for your product; Amazon's page describes self-test for products under 50 lb that do not contain liquids or sharp items.
• Ask whether sensitive items need opaque or discreet packaging and plan labels accordingly.

Design inputs that affect test outcomes

A box that looks strong can still perform poorly if the product shifts inside it. Design for the product's center of mass, not just its footprint. Use inserts, partitions, or retention features to limit movement, and check that the closure stays secure after repeated handling. Surface protection matters too: a printed shipper should not scuff the product or hide damage behind graphics.

For flexible packaging, follow Amazon's flexible packaging guidelines rather than forcing a rigid box approach. For rigid packaging, consider board grade, corner crush, print coverage, and how the pack will be opened. The goal is a pack that protects the product, presents the brand, and gives a reviewer clear evidence of how it was tested.

A simplified geometry exercise

Suppose a hypothetical rigid box holds a 1.2 kg folded textile product measuring 240 mm by 160 mm by 80 mm. You plan 5 mm clearance on each side, part of which a paperboard insert will occupy. The internal box dimensions become 250 mm by 170 mm by 90 mm: add 10 mm to each product dimension. With a hypothetical 2 mm board thickness on each wall, a simplified external estimate is 254 mm by 174 mm by 94 mm: add 4 mm to each internal dimension. This estimate ignores flaps, glue overlaps, and caliper tolerances. The internal volume is 250 times 170 times 90, which equals 3,825,000 cubic mm, or 3.825 liters. The product volume is 240 times 160 times 80, which equals 3,072,000 cubic mm, or 3.072 liters. The difference is 3.825 minus 3.072, or 0.753 liters, which is about 19.7 percent of internal volume. That figure is gross clearance before the insert, not empty air. The actual unfilled space will be smaller once the insert is added.

These numbers are a geometry check only. They are not a usable capacity, a dieline, or a test result. The insert, board grade, and closure design still need prototyping. Use the exercise to compare concepts, not to certify a box. If you reduce clearance, you may improve retention but make loading harder. If you increase board thickness, external dimensions grow and the product-to-packaging ratio changes. Record the assumptions so a converter and a test lab can review them.

Prototype, test, and keep evidence

Use early mockups to explore fit, then plan test samples that represent the intended production materials, inserts, closures, and relevant printing or finishing. Confirm sample preparation requirements with Amazon's current instructions or the test provider. Amazon's page says a third-party lab can perform an ISTA 6 lab test and provide an ISTA-6A lab report for certification. It also says self-testers should evaluate results and take the required photos. We recommend keeping a test log that a reviewer can follow.

• Record product weight, dimensions, packaging materials, and insert type.
• Photograph the pack before and after handling, including closure and product condition.
• Test the largest or heaviest item in each group, as the page directs.
• Keep any lab report, corrective action log, and revised sample notes together.
• After a material, insert, or artwork change that could affect protection, assess the need for retesting with Amazon's current instructions or your test provider.
• Report test results according to the applicable procedure, and distinguish a passing test result from Amazon's certification or enrollment decision.

Artwork and prepress checks for a printable shipper

Packaging artwork has two jobs: it must print correctly and it must not hide the dieline or finishing instructions. Ask your converter which PDF standard, page boxes, marks, layer structure, and proof type they require. Adobe's documentation explains that printer marks show document boundaries such as trim and bleed, and that marks can be embedded in a separate layer. It also explains that page boxes define media, trim, bleed, and art boundaries. Those are useful controls, but the converter's instructions decide which marks and boxes belong in the file.

Use output preview to inspect separations and color warnings before handoff. Adobe notes that onscreen separation preview does not verify trapping, printer marks, halftone screens, or resolution; those are better checked with the print provider using integral or overlay proofs. PDF/X-4 can carry color-managed RGB, and the printer's agreed workflow determines conversion, so do not assume every RGB element must be converted by you. Registration black is distinct from rich black; use the converter's specification for which black belongs on which element. Named spot colors may be simulated in digital workflows, while workflows that use plates can build actual spot plates. Confirm the proof type and approval route.

Practical checklist

This checklist is Teal's editorial planning framework. It does not replace Amazon's current program instructions or a lab's test procedure.

• Confirm SIPP eligibility and current program terms in your seller account.
• Confirm whether your product can self-test or needs a third-party lab.
• Group SKUs by the factors Amazon lists and document the grouping.
• Choose the largest or heaviest item in each group as the test representative.
• Build samples with production-intent materials and inserts.
• Record product weight, dimensions, and center of mass assumptions.
• Check product retention, closure security, and surface protection.
• Review the dieline, page boxes, printer marks, and layer structure with the converter.
• Approve a proof type that the converter specifies; do not rely on a screen preview for trapping or marks.
• Keep test photos, lab reports, artwork approvals, and corrective actions together.
• Review material, insert, or artwork changes with the test provider and confirm whether Amazon's current instructions call for retesting.

Scope limits

This guide does not determine Amazon eligibility, does not set test pass criteria, does not certify a package, and does not replace ISTA 6 procedures or lab judgment. It does not provide a manufacturable dieline or promise a fulfillment discount. Discount amounts and program terms can change; the Amazon page states a range of $0.04 to $1.32 per certified item, but confirm current terms in your account. Teal does not certify SIPP or SIOC performance, and a sample or prototype is not a certification. For legal, tax, food safety, hazardous, cold shipping, or restricted product questions, use a review workflow with the responsible experts and your channel agreement.
