SOURCING TASK GUIDE · PRODUCT CHECKS
Check FBA label samples before batch application
Amazon FBA fulfillment centers enforce strict labeling and barcode rules. Barcodes with small quiet zones, low contrast, or placement over package seams risk intake rejections and inventory receiving delays.
Zhipact coordinates sample FBA label and barcode checks at an agreed partner facility, testing 1D/2D barcode scan response on handheld scanners, verifying label position against Amazon rules, and checking text contrast.
What you share for this task
- Amazon FNSKU label PDF files generated directly from Seller Central.
- Product packaging specifications, polybag dimensions, and carton dielines.
- Amazon marketplace destination guidelines (e.g., Amazon US, UK, or EU).
- Sample labeled product units or sample packaging mockups from your factory.
What we coordinate and deliver
- A sample label placement record with photos and the reference file used.
- Handheld scan attempts recording the device, decoded value and sample conditions.
- Observed clear space and placement compared with the applicable marketplace requirements.
- A record of supplied warning text and print-size checks within the agreed scope.
PRACTICAL RISK POINTS
Three critical issues to resolve before sample approval
Key physical checkpoints to verify against specifications before production.
1. Underlying manufacturer UPC or EAN barcodes visible through label
The situation: Semi-translucent label stock applied over factory barcodes, allowing warehouse scanners to read the wrong code.
How we check it in China: We inspect labeled samples under direct light for barcode bleed-through, and perform test scans over covered regions.
The record & next decision: Opacity photos and scan results indicate whether opaque block-out label stock or barcode removal is needed.
2. Barcodes lacking required quiet zones or placed too close to polybag seams
The situation: FNSKU barcodes printed without adequate quiet zones or placed too close to polybag seams and package edges.
How we check it in China: We compare left, right, top and bottom clear space with the approved label file and current destination requirements. Package-edge clearance is checked separately, and folds or seams that distort the barcode are recorded.
The record & next decision: A barcode placement log records measured border distances and edge clearances, allowing dieline corrections.
3. Low thermal print contrast causing handheld scanner decode failures
The situation: Low-contrast thermal printing or blurred bar edges causing scan failures on warehouse scanners.
How we check it in China: We record decode attempts with the agreed handheld device. Formal print-quality verification requires a suitable verifier, method and provider; a successful scan alone is not a quality grade.
The record & next decision: A scan log records decode speed, readability, and contrast photos, providing actionable feedback to adjust printer settings.
| Sample | Reference | Observed clear space | Placement | Handheld scan | Next step |
|---|---|---|---|---|---|
| Sample A | Approved FNSKU PDF, Rev A | Left/right 0.30 in; top/bottom 0.15 in | Flat face; package-edge gap 0.30 in | Decoded to expected value | Submit record for approval |
| Sample B | Approved FNSKU PDF, Rev A | Left/right 0.15 in; top/bottom 0.15 in | Flat face; package-edge gap 0.30 in | Decoded on test device | Widen side clear space; scan success does not override the requirement |
| Sample C | Approved FNSKU PDF, Rev A | Right side clipped by artwork | Code bends over a fold | Intermittent decode | Correct artwork and placement; review another sample |
Clear execution roles and agreed boundaries
Eddie leads checkpoint review and the next decision. Coordination colleagues align sample references, logistics and follow-up records. Before work starts, the scope identifies who performs each check, the location, suitable instruments and the reporting method.
Transparent fee structure: Sourcing coordination is quoted as an agreed service fee. Physical handling, kitting or checks follow agreed task rates via partner facilities. Reimbursable third-party expenses require written approval.
COMMON QUESTIONS
Frequently asked about this task
Can you verify whether our suffocation warning font size meets Amazon guidelines?
We compare the supplied warning text and print size with the applicable marketplace requirements and bag dimensions. Where a rule uses bag length plus width, we record that measurement rather than perimeter. The requirement, source and date are confirmed before batch approval.
Does a successful handheld scan test guarantee Amazon warehouse acceptance?
Handheld tests confirm decodability. Amazon intake also depends on print contrast, quiet zones, label placement on flat surfaces, and packaging rules.
