Selling through Amazon FBA (Fulfillment by Amazon) is one of the fastest ways to build a successful eCommerce business. By allowing Amazon to store, pack, and ship your products, you can focus on growing your brand and increasing sales. However, before your products reach an Amazon fulfillment center, they must be properly prepared according to Amazon’s strict packaging, labeling, and quality requirements.
If your products are incorrectly labeled, poorly packaged, or fail to meet Amazon FBA standards, you may face shipment delays, additional preparation fees, inventory rejection, or even account performance issues. That’s why preparing products correctly before they leave China is one of the most important steps in the sourcing process.
In this guide, you’ll learn how to prepare products for Amazon FBA in China, avoid common mistakes, and discover how Auronix Sourcing helps Amazon sellers ship inventory to FBA warehouses with confidence in 2026.

Why Prepare Products Before Shipping?
Amazon has strict requirements for products entering its fulfillment centers. Proper preparation helps ensure your inventory is received quickly, stored correctly, and delivered safely to customers.
Benefits of proper Amazon FBA preparation include:
- Faster inventory check-in
- Fewer shipment delays
- Lower risk of damaged products
- Reduced Amazon prep fees
- Better customer experience
- Fewer returns and complaints
- Improved seller performance
Preparing products correctly also protects your brand reputation and saves money in the long run.
Step 1: Conduct a Product Quality Inspection
Before packaging begins, inspect your products to ensure they meet your quality standards.
A professional inspection should verify:
- Product appearance
- Dimensions and weight
- Material quality
- Functionality
- Color consistency
- Accessories included
- Workmanship
Catching defects before shipment prevents costly returns and negative customer reviews.
Step 2: Apply Amazon FNSKU Labels
Every product sent to Amazon FBA requires a unique FNSKU (Fulfillment Network Stock Keeping Unit) label unless you are using the manufacturer barcode option.
Ensure:
- One FNSKU label per unit
- Labels are easy to scan
- Old barcodes are covered
- Labels are placed on a flat surface
- No wrinkles or damage
Incorrect labeling can delay receiving or cause inventory mix-ups.
Step 3: Follow Amazon Packaging Requirements
Amazon requires products to be packaged securely to withstand shipping and warehouse handling.
Packaging should:
- Protect the product from damage
- Be clean and professional
- Use durable materials
- Prevent leakage or contamination
- Meet Amazon size requirements
Products that are fragile, sharp, or liquid require additional protective packaging.
Step 4: Use Poly Bags or Bubble Wrap When Needed
Some products need extra protection before shipping.
Common protective materials include:
- Poly bags
- Bubble wrap
- Foam inserts
- Protective sleeves
- Shrink wrap
For products packed in poly bags, ensure they include suffocation warning labels when required by Amazon.
Step 5: Bundle Products Correctly
If you’re selling multipacks or product bundles, ensure each set is packaged together securely.
Bundles should:
- Stay together during shipping
- Include all components
- Display a single FNSKU label
- Be clearly marked as a set
Incorrect bundling may cause inventory errors or customer complaints.
Step 6: Verify Product Weight and Dimensions
Accurate measurements are important because Amazon uses product dimensions to calculate storage and fulfillment fees.
Confirm:
- Product weight
- Package dimensions
- Carton dimensions
- Carton weight
Incorrect measurements may result in unexpected FBA charges.
Step 7: Prepare Shipping Cartons
Outer cartons must protect products during international shipping.
Inspect each carton for:
- Strong corrugated cardboard
- Secure sealing
- Proper weight distribution
- No visible damage
- Correct carton size
Avoid overfilling cartons, as this increases the risk of shipping damage.
Step 8: Apply Carton Labels
Every shipping carton should include the correct Amazon shipping labels.
Verify:
- Amazon shipment ID labels
- Carrier labels
- Carton numbering
- Destination warehouse information
- Barcode readability
Incorrect carton labels can delay receiving at Amazon fulfillment centers.
Step 9: Perform a Final Pre-Shipment Inspection
Before your shipment leaves China, conduct one final inspection.
Inspectors should verify:
- Product quality
- Quantity
- Packaging
- Labels
- Cartons
- Shipping documents
- FNSKU placement
A final inspection provides peace of mind before inventory is shipped.
Step 10: Arrange Shipping to Amazon FBA
Once products are prepared and approved, choose the best shipping method.
Air Freight
Ideal for:
- Urgent inventory
- Small shipments
- High-value products
Sea Freight
Best for:
- Bulk orders
- Lower shipping costs
- Large inventory shipments
Working with an experienced logistics partner ensures smoother customs clearance and timely delivery to Amazon warehouses.
Common Amazon FBA Preparation Mistakes
Many sellers experience delays because they:
- Forget FNSKU labels
- Use poor-quality packaging
- Skip quality inspections
- Ship damaged products
- Apply incorrect carton labels
- Ignore Amazon packaging guidelines
- Use weak shipping cartons
Avoiding these mistakes reduces costs and improves operational efficiency.
