What the supplier called "perfect" — we flagged 23 packaging violations in 90 minutes.
Poly bag thickness wrong. Suffocation warning missing. Overboxing on 8 ASINs.
You're about to send your first (or fiftieth) FBA container from China. The products are ready. The supplier says everything is packed correctly. But Amazon's inbound team sees things differently — and they don't do warnings. They reject, return, or charge you extra.
Amazon FBA packaging inspection China is the safety net most sellers only get after their first rejection. Let's make sure you're not one of them.
Why FBA Packaging Inspection Matters
In 2025, Amazon updated its inbound packaging requirements. The changes weren't small. Carton weight limits got stricter. Poly bag rules expanded. Label placement requirements became more specific.
Here's what's at stake:
| Issue | Cost |
|---|---|
| ❌ Shipment rejected at inbound | $500–$2,000 return freight |
| ❌ Disposal fee per rejected unit | $0.15–$1.50 per unit |
| ❌ Lost sales (2–4 weeks delay) | $3,000–$15,000 in missed revenue |
| ❌ Suppression of ASIN for policy violations | Unknown — weeks to reinstate |
| ✅ FBA packaging inspection (1 man-day) | $169 |
💰 $169 vs. $500+ in return shipping alone. The math isn't complicated.
Amazon FBA Packaging Requirements You Must Know
Amazon's FBA packaging requirements cover every layer of your shipment. From the outer carton down to the individual poly bag. Here are the non-negotiable rules:
| Requirement | What Amazon Expects |
|---|---|
| Carton strength | Corrugated boxes only. No damaged, crushed, or water-stained cartons. Must survive 2+ meter drops. |
| Carton weight | Max 50 lbs (22.7 kg) per carton. Overweight = rejected, no exceptions. |
| Poly bag thickness | Minimum 1.5 mils. Bags must be sealed with no tears. |
| Suffocation warning | Required for any bag with opening ≥5 inches. Must be printed on the bag (not a sticker). |
| FNSKU label | Scannable, not covered by tape or other labels. Must be on the outside of the poly bag or product packaging. |
| Country of origin | "Made in China" clearly printed on each unit or its packaging. |
| Bundle/set integrity | Items sold as a set must be bagged together, sealed, and labeled as a single unit. |
| Overboxing | Each ASIN in its own master carton. No mixing unless Amazon approves commingled FBA. |
⚠️ Important: These are Amazon's requirements as of Q2 2026. The Amazon FBA inspection China page has the full updated policy list.
What We Check During FBA Packaging Inspection
When CloudSpects sends an inspector for Amazon inbound compliance inspection, here's the exact checklist we follow:
📦 Carton strength and condition
We check every carton for structural integrity. Crushed corners. Water damage. Tape that's peeling off. Cartons that look like they've been stacked in a damp warehouse for three months. If a carton won't survive the journey to an Amazon FC, we flag it.
🛍️ Poly bag thickness and suffocation warning labels
This is the #1 failure point we see. Suppliers buy cheap poly bags that measure 1.2 mils instead of the required 1.5. Or they order bags with the suffocation warning printed — but it's so faded you can't read it. The poly bag suffocation warning inspection is quick, but it catches violations that would get your entire ASIN rejected.
🔗 Bundle / set integrity
You sell a 3-piece set. The factory packs all 3 pieces in one poly bag — good. But one piece falls out during transit because the seal isn't strong enough. Amazon treats it as a missing item. We check that every bundle is properly sealed and labeled as a set.
🏷️ FNSKU and barcode placement
Scannable from 6 inches. Not covered by tape. Not placed where another label covers it. Not wrinkled or peeling. Our dedicated FNSKU inspection China service goes further — testing every barcode with handheld scanners to ensure 99.5%+ first-pass read rate at Amazon. This is the single most common FBA rejection reason, and it is completely preventable with proper pre-shipment verification.
🌏 Country of origin labels
"Made in China" must be on the product or its immediate packaging — permanently. Not on the master carton. Not on a sticker that falls off. This is a US Customs requirement, not just an Amazon rule. Missing COO labels = customs hold.
📦 Overboxing and bubble wrap requirements per ASIN
Each ASIN must be in its own carton unless Amazon has approved mixed-box FBA. We also check that fragile ASINs have proper bubble wrap — not just a few scraps of paper thrown in for "padding" (yes, suppliers do this).
Common FBA Packaging Rejection Reasons
Based on our inspection records from 200+ FBA shipments in 2025-2026, here are the top reasons shipments get rejected at Amazon inbound:
- Poly bag thickness below 1.5 mils — 34% of our failed inspections had this issue
- Missing suffocation warning — 28% of poly bags sent from Chinese factories lack the required warning
- FNSKU label unreadable — labels printed on thermal paper that fades in 2 weeks, or labels covered by clear packing tape
- Carton over 50 lbs — suppliers overpack to save on shipping, not realizing Amazon will reject anything over the limit
- Mixed ASINs in one carton — supplier thinks it's fine because "they're all going to the same warehouse"
- Missing country of origin — the label was on the master carton, not the individual unit
🔥 The worst part? All six of these are preventable with a 90-minute Amazon packaging compliance check before the container leaves.
FBA Packaging Inspection Step by Step
Step 1: Review shipment documentation
We get your packing list and ASIN breakdown. This tells us what goes into which carton, so we know exactly what to look for.
Step 2: Visual carton inspection
Every carton gets a visual check. 100% of them. If we find damage or weakness, we flag the carton and note why.
Step 3: Open and inspect packaging per ASIN
Sample cartons opened. Poly bags measured with a mil gauge. Barcodes scanned with a verifier. Suffocation warnings confirmed readable. Bundles checked for seal integrity.
Step 4: Label verification
Every FNSKU label must scannable. Every "Made in China" label present. Every suffocation warning visible.
Step 5: Report and remediation
Same-day report with photos. Every violation documented with a photo. If the factory can fix it before the container loads, we tell you exactly what needs to change.
Real inspection: FBA electronics shipment, Shenzhen
An FBA seller from Texas ordered 850 Bluetooth earbuds from a Shenzhen factory. The factory claimed the packaging was "Amazon-ready." Our inspector found:
- ❌ 14 cartons over 50 lbs — the heaviest was 68 lbs
- ❌ Poly bags at 1.1 mils — factory ordered cheap stock without checking
- ❌ FNSKU labels on 32 units unreadable — thermal transfer printer was running low on ribbon
- ✅ The factory fixed everything in 6 hours. The container shipped on time.
💰 The seller paid $169 for the inspection. Without it, those 14 overweight cartons would have been rejected at Amazon inbound — triggering a $680 return shipping fee plus restocking delays that would have killed a Prime Day launch.

FAQ
What is Amazon FBA packaging inspection China?
It's a pre-shipment check at your Chinese supplier's factory that ensures every carton, poly bag, and label meets Amazon FBA inbound rules. Inspectors verify carton strength, suffocation warnings, FNSKU labels, and more before your goods leave.
How much does FBA packaging inspection in China cost?
CloudSpects charges $169 per man-day for standard FBA packaging inspection (AQL 2.0-4.0 sampling). Most FBA shipments of 200-800 units need just one day. Full 100% inspection pricing available per project.
What happens if my FBA shipment fails packaging inspection?
Amazon can reject the entire inbound shipment. You pay return shipping, disposal fees, and lose selling time. A FBA packaging inspection China before shipment costs a fraction of a single rejection.
What poly bag requirements does Amazon have for FBA?
Poly bags must be at least 1.5 mils thick. Bags with openings 5 inches or wider need a suffocation warning label — printed on the bag, not a sticker. No exceptions.
Do I need FBA packaging inspection if my supplier has QC?
Supplier QC checks product defects — not Amazon packaging compliance. Factory QC teams rarely know FBA's specific carton weight limits, label placement rules, or poly bag thickness requirements. You need a separate check focused on Amazon inbound compliance inspection.
🔍 First time with a new supplier? Don't skip the factory audit China step. A factory audit verifies the supplier's production capacity, quality management, and compliance systems before you place your order — catching issues before they become packaging defects.
