Why Prep FBA Inventory in China?

Most Amazon sellers source products from Chinese factories. Once goods leave the factory, there are two options: ship directly to a destination-country prep center, or prep in China before exporting. The second option almost always wins on cost and speed.

Labor cost advantage. Prep work — labeling, poly bagging, bundling — is labor-intensive. Labor costs in South China are a fraction of what you'd pay in the US, UK, or Germany. The same prep job that costs $0.50–$1.50 per unit in a US fulfillment center can be done for significantly less in China.

Eliminate the double-shipping leg. When you prep in China, goods flow in one direction: factory → Rayfill warehouse → Amazon FC. If you ship unprepped goods to a destination prep center first, you're paying for an extra freight leg and adding 1–3 weeks to your restock timeline.

Catch factory defects before export. When Rayfill receives your goods from the factory, we count and inspect as part of our intake process. Quality issues identified at this stage cost almost nothing to fix. The same issues identified at an Amazon FC cost significantly more — or result in the shipment being returned.

What's Included in Rayfill FBA Prep

Every prep task done to Amazon's current requirements for the target marketplace.

FNSKU Labeling

We print FNSKU barcodes from your Amazon shipment plan and apply them to each unit. Correct placement, correct size, no obscuring of manufacturer barcodes unless required. Supports all FNSKU formats across US, UK, EU, CA, AU marketplaces.

Poly Bagging

Products that require poly bagging per Amazon's category rules are sealed in clear poly bags with a suffocation warning label (text printed directly on bag or as a separate label). Bags are sealed airtight. Correct bag thickness per Amazon requirements.

Bundle & Multi-Pack Creation

We create multi-packs (e.g., 3-pack, 6-pack) or product bundles from individual units. Each bundle is shrink-wrapped or poly-bagged with a single FNSKU label covering the combined SKU. Counts are verified per bundle against your shipment plan.

Carton Marking & Box Content Labels

Every shipping carton is labeled with the correct Amazon box content label (including ASIN, FNSKU, quantity, and box weight). Carton dimensions and weights are recorded for your shipment plan. Palletizing available for large volume shipments.

Barcode Removal / Cover

When Amazon requires removal or covering of manufacturer barcodes (e.g., EAN/UPC that conflict with FNSKU), we handle this in-house. Manufacturer barcodes are covered with opaque labels to prevent FC scanner confusion.

Pre-Shipment Verification

Before dispatch, we cross-check quantities against your Amazon shipment plan, verify unit counts per carton, and confirm all labels are correctly applied and scannable. Discrepancies are reported to you before the shipment is sealed and released.

FBA Prep FAQ

What is Amazon FBA prep and why does it matter?
Amazon FBA prep refers to all the preparation work required before sending inventory to an Amazon Fulfillment Center (FC). This includes FNSKU barcode labeling, poly bagging, suffocation warning labels, bundle creation, and carton marking. If these requirements are not met exactly, Amazon will either refuse the shipment at the FC, charge you a prep fee on-site, or return the goods — all of which cause delays and added costs.
Why prep FBA inventory in China rather than at a US or UK warehouse?
Prepping in China is significantly cheaper. Labor costs for labeling and packaging in South China are a fraction of what you'd pay in the US or UK. More importantly, prepping at the origin eliminates a double-shipping leg — goods go directly from your supplier to our warehouse, get prepped, and ship straight to the Amazon FC. This saves both time and cost compared to shipping unprepped goods to a destination-country prep center first.
What does Rayfill's FBA prep service include?
Rayfill FBA prep includes: FNSKU barcode printing and application, poly bagging with suffocation warning labels, multi-pack bundle creation, carton content labeling, box weight and dimension compliance, and a pre-shipment check against your Amazon shipment plan. We also handle removal of manufacturer barcodes when required.
Can Rayfill prep products that come directly from my factory?
Yes — this is our most common workflow. Your factory ships goods directly to our Shenzhen or Dongguan warehouse. We receive, count, inspect, and prep to Amazon FC requirements before forwarding the shipment. You do not need a separate quality check or logistics step in between.
How long does FBA prep take at Rayfill?
Standard FBA prep turnaround is 2–5 business days from the time goods arrive at our warehouse, depending on volume and complexity. Poly bagging and bundle creation take longer than labeling-only orders. Rush turnaround can be arranged for time-sensitive restocks.
Does Rayfill prep for Amazon marketplaces outside the US?
Yes. We prep for Amazon US, UK, Germany, France, Italy, Spain, Canada, Australia, and Japan. Requirements differ slightly by marketplace — particularly for EU shipments post-Brexit — and we stay current with Amazon's prep requirements for each region.
What shipping options are available after FBA prep?
After prep, your inventory can be shipped via sea freight (FCL or LCL) for bulk shipments, air freight for time-sensitive restocks, or our hybrid shipping option which combines sea freight pricing with last-mile delivery. We handle all freight forwarding to the destination Amazon FC.
How does Rayfill stay current with Amazon's prep requirements?
We actively monitor Amazon's seller central announcements and prep requirement updates across all active marketplaces. When requirements change, we update our internal prep SOPs immediately. We also communicate relevant changes directly to affected clients to avoid any compliance gaps.
