Amazon FBA Prep Checklist for New Sellers

An Amazon FBA Prep Checklist helps new sellers avoid the expensive mistakes that happen before inventory ever reaches an Amazon fulfillment center. A product can be profitable, well sourced and well marketed, but if it arrives with the wrong label, weak packaging, incorrect carton data or missing prep, the shipment can be delayed, rejected, relabeled, repacked or made unavailable for sale.

FBA is attractive because Amazon can store inventory, pick orders, pack products, ship to customers and handle many customer service and return tasks. Amazon's public FBA overview explains the basic model and the Send to Amazon workflow, including preparation, packing and labeling steps. Sellers should also review the current Seller Central help pages for preparing, packing and labeling inventory before every shipment because requirements can change by marketplace, product type and shipment workflow.

This guide gives new sellers a practical Amazon FBA prep checklist for products sourced in China. It explains what to confirm before production, what to inspect before shipping, how labeling should be planned, why carton rules matter and how Fyllhub can support Amazon FBA prep service from China.

Start Before Production

FBA prep should not begin after cartons are finished. The best time to reduce FBA risk is before the supplier prints packaging, applies barcodes or seals the first carton. New sellers often treat prep as a warehouse task, but many prep problems are manufacturing and data problems.

Before production, confirm:

• Product eligibility for FBA
• Marketplace and destination country
• Listing status and ASIN assignment
• SKU naming convention
• Barcode strategy
• Unit packaging requirements
• Bundle or multipack rules
• Carton size and weight limits
• Hazardous material or battery status
• Fragile, liquid, sharp or textile prep needs
• Country-of-origin marking needs
• Inspection criteria
• Target shipping method

If any of these items are unclear, the seller should pause and resolve them before mass production. A cheap fix before production can become an expensive relabeling or repacking job after production.

Check Product Eligibility

The first item on any Amazon FBA Prep Checklist is product eligibility. Not every product can be sent to FBA without extra approval, documentation or restrictions. Categories, brands, product types, dangerous goods status, batteries, liquids, cosmetics, food, supplements, toys and electronics can all involve additional rules.

Sellers should review Amazon's current FBA policies and product restrictions in Seller Central before buying inventory. They should also confirm marketplace-specific requirements. A product that can be sold in one marketplace may need different documentation in another.

For planning, sellers can use Amazon's official Fulfillment by Amazon overview as a starting point, then check the current Seller Central requirements for the specific ASIN and destination. Public pages are useful for orientation, but Seller Central is where product-level eligibility and workflow details are confirmed.

Prepare Listing and SKU Data

Accurate listing data makes the physical prep process easier. A warehouse cannot label and pack correctly if the seller's SKU data is messy.

Before sending products to a China prep warehouse, prepare:

• Seller SKU
• ASIN or listing status
• Product name
• Product photo
• Variation details
• Color, size and model
• Unit weight and dimensions
• Carton weight and dimensions
• Units per carton
• Barcode type
• FNSKU label file if required
• Bundle or multipack instructions
• Expiration date if relevant
• Prep category if known
• Supplier contact and purchase order details

The SKU code should be stable and unique. New sellers should avoid using supplier product names as warehouse identifiers because supplier names often change. Clean SKU data reduces wrong labels, mixed cartons and receiving confusion.

Choose the Right Barcode Plan

Barcode mistakes are one of the most common FBA problems. Each sellable unit needs to be identifiable in a way Amazon accepts for that product and marketplace. Depending on the listing and product, sellers may use manufacturer barcodes, Amazon barcodes such as FNSKU labels, or other approved identifiers.

Sellers should confirm the barcode requirement in Seller Central before printing packaging. If the product requires an Amazon barcode, the FNSKU must be printed clearly, applied to the correct unit and placed so it can be scanned. Any other visible barcode that could confuse scanning may need to be covered.

A barcode plan should answer:

• Is the product using manufacturer barcode or Amazon barcode?
• Does every variation have a unique identifier?
• Will the supplier print the barcode on packaging?
• Will the prep warehouse apply FNSKU labels?
• Are old barcodes covered?
• Is the barcode scannable after shrink wrap or poly bagging?
• Does the label fit the unit packaging?
• Are there multiple marketplaces with different labels?

New sellers should not let a supplier print barcodes until the listing and barcode plan are confirmed. Reprinting packaging is expensive. Applying labels at a China prep center is often safer when product data may still change.

Unit Packaging Checklist

Unit packaging protects the product and helps Amazon receive, store and ship it properly. The right packaging depends on the product, but the goal is always the same: each sellable unit should arrive ready to be received and fulfilled.

Check each unit for:

• Correct SKU
• Correct variation
• Clean outer packaging
• No loose pieces
• No exposed sharp edges
• No leaking liquid
• No crushed boxes
• Clear barcode
• Correct warning label if needed
• Secure closure
• Proper bundle or set assembly
• Product insert only if allowed by Amazon policies
• No unauthorized marketing claims
• No supplier invoice or factory paperwork inside

The product should not rely on Amazon staff to understand special instructions. The unit should be obvious, scannable and ready for the fulfillment center process.

Poly Bags, Bubble Wrap and Extra Prep

Some products need extra prep before they can be sent to FBA. Examples may include apparel, textiles, plush products, liquids, fragile goods, sharp items, baby products, loose accessories, multi-piece sets and products that need dust protection.

Common prep types include:

• Poly bagging
• Bubble wrap
• Opaque bagging
• Suffocation warning labels
• Set labels
• Fragile labels
• Expiration date labels
• Tamper seals
• Carton reinforcement
• Inner box protection

Sellers should confirm the required prep category in Seller Central and in Amazon's current preparing inventory guidance. Some Seller Central help pages require JavaScript or login, but the rule for sellers is simple: check the current official workflow before every shipment.

If a supplier handles prep, the seller should still inspect samples. Supplier packaging may look acceptable in photos but fail scanning, protection or labeling requirements when checked unit by unit.

FBA Labeling Checklist

FBA labeling connects the product, carton and shipment plan. A label mistake can cause stranded inventory, receiving delays, extra fees or incorrect sales data.

Check labels for:

• Correct FNSKU or barcode for each unit
• Correct label size
• High contrast print
• No smudging
• No scaling distortion
• Scannable placement
• No label over a corner or seam
• No old barcode left uncovered
• Correct marketplace
• Correct variation
• Correct carton labels
• Shipment labels matched to the shipment plan

If the seller uses a China prep partner, the warehouse should scan or spot-check labels before cartons are sealed. For high-volume shipments, the seller may request a photo report showing label placement by SKU.

Fyllhub also has a dedicated guide to Amazon FBA labeling requirements for sellers who want a deeper labeling workflow.

Bundle and Kitting Checklist

Bundles and kits create more room for mistakes because several items become one sellable unit. A kit may include a main product, accessory, instruction card, cable, spare part or branded insert. If one component is missing, the entire unit can create customer complaints or returns.

Before shipping bundles to FBA, confirm:

• Bundle ASIN and SKU are correct
• Every component is listed in the assembly rule
• Quantity per component is correct
• Packaging keeps the bundle together
• Unit is clearly marked as a set if required
• Barcode represents the bundle, not an individual component
• Old component barcodes are covered if necessary
• Weight and dimensions are updated after assembly
• A sample kit has been inspected

Kitting should be handled with a written packing standard. Photos help, but they are not enough. The warehouse should know the exact component list, placement and final packaging requirement.

Sellers that need this workflow can review Fyllhub's FBA kitting guide and use a China warehouse to assemble kits before FBA shipment.

Carton Checklist

Carton preparation matters because Amazon receives inventory by shipment and carton. A product can be labeled correctly at the unit level but still create problems if carton labels, box contents or weights are wrong.

Check cartons for:

• Correct units per carton
• Carton weight within marketplace limits
• Carton dimensions within shipment rules
• Strong outer carton
• No damaged or wet cartons
• No mixed SKUs unless the shipment plan allows it
• Correct carton label
• Shipment label applied flat
• Old shipping labels removed or covered
• Carton number matches the packing list
• Box contents are accurate
• Carton photos are saved before dispatch

New sellers should pay attention to box contents. If the workflow requires box content information, inaccurate data can slow receiving and create avoidable fees. The prep warehouse should be able to provide carton-level data clearly.

Master Cartons and Mixed SKUs

Mixed SKU cartons can be convenient for small test shipments, but they add risk. If Amazon expects a single SKU carton and receives mixed inventory, receiving can become messy. If a China prep warehouse mixes SKUs without accurate carton data, the shipment may be delayed.

Use single-SKU cartons when possible for cleaner receiving. If mixed cartons are necessary, the packing list should be exact. It should show which SKUs and quantities are inside each carton.

New sellers should avoid asking suppliers to combine random leftovers into cartons without a packing map. That may save a little time at the factory but create expensive confusion at the fulfillment center.

Inspection Before FBA Prep

Inspection is not the same as prep, but it belongs in the same workflow. Amazon customers judge the final product, not the supplier's promise. If defective units enter FBA, the seller may face returns, bad reviews, account health issues and removal costs.

Before labeling and packing, inspect:

• Carton count
• Unit count
• Product appearance
• Color and size
• Function
• Accessories
• Packaging condition
• Barcode or label area
• Obvious defects
• Sample weight and dimensions
• Bundle components
• Instructions and inserts

For higher-risk products, sellers can request FBA inspection in China before prep. Inspection should happen before final labeling when possible, because defective units should not receive labels or be shipped to FBA.

Create the Shipment Plan Carefully

The Send to Amazon workflow creates the shipment instructions that connect products, box contents, labels and destination. Amazon's public FBA page describes the general process and links to the official Send to Amazon preparing, packing and labeling guidance.

Before final dispatch, confirm:

• Correct marketplace
• Correct ship-from address
• Correct SKUs and quantities
• Correct case pack or individual units
• Accurate unit dimensions and weight
• Accurate carton dimensions and weight
• Correct shipment labels
• Correct carrier or freight method
• Correct delivery appointment process if needed
• Box contents submitted correctly

Do not create the shipment plan before inventory details are known. If quantities, cartons or dimensions change after the plan is created, labels and box contents may need to be updated.

Freight and Delivery Checklist

FBA prep does not end when cartons leave the warehouse. The shipment still needs to reach the assigned Amazon fulfillment center or receiving point.

Check freight details:

• Shipping method: courier, air, sea, express or truck
• Destination fulfillment center
• Carrier requirements
• Customs documents
• Commercial invoice
• Packing list
• Export documents
• Duty and tax handling
• Delivery appointment if required
• Tracking number
• Proof of pickup
• Estimated arrival date
• Exception monitoring

For products sourced in China, sellers often combine prep with Amazon FBA shipping from China. This reduces handoff risk because the prep partner understands the cartons, labels and shipment plan before arranging freight.

Amazon Prep Service vs China Prep Service

Some sellers use Amazon's available prep or labeling services where offered. Others use a China prep service before inventory leaves the origin country. Both can be useful, but they solve different problems.

Amazon prep services may help when inventory arrives unprepared and the product is eligible for the service. However, relying on after-arrival correction can add cost, delay and uncertainty. A China prep service lets sellers inspect, label, bundle, repack and correct issues before international shipping.

China prep is especially useful when:

• Suppliers are in China
• Products need inspection before export
• Packaging needs to be corrected
• Bundles need assembly
• FNSKU labels need to be applied
• Multiple suppliers need consolidation
• Carton data must be organized
• Freight from China needs coordination

For many new sellers, the best approach is to prep correctly before shipment and treat Amazon receiving as the final destination, not the place where basic errors should be fixed.

Common FBA Prep Mistakes

Sending inventory before listing data is final

If the listing, ASIN, SKU or barcode plan changes after products are labeled, the seller may need to relabel everything. Confirm listing data first.

Letting suppliers choose labels

Suppliers may not understand Amazon requirements. The seller should provide label files and written instructions or use a prep partner that specializes in FBA.

Forgetting to cover old barcodes

If multiple barcodes are visible, scanning confusion can happen. Confirm which barcode should be scannable.

Using weak cartons

International shipping can crush weak cartons. Damaged cartons can lead to receiving issues and product damage.

Skipping inspection

Prep makes products compliant, but it does not make bad products good. Inspect before sending units to Amazon.

Mixing SKUs without a carton map

Mixed cartons need accurate box contents. Without carton-level data, receiving can become slower and more expensive.

Ignoring dimensions and weight

Wrong dimensions can affect fees, shipping cost and shipment planning. Measure after final packaging, not before.

Treating one marketplace rule as universal

Amazon requirements vary by marketplace and product. Sellers should verify current rules for the exact destination.
