Amazon FBA Prep

Amazon FBA prep done right. From a warehouse minutes from the port.

FNSKU labeling, polybagging, bundling, palletization, ASN transmission. Inbound from Asia clears the Port of Long Beach and arrives at our dock the same day — meaningfully faster than East Coast prep services.

What's included

FBA prep workflow.

Amazon's prep requirements are strict and Amazon's penalties for violations are expensive. Here's exactly what we do for every inbound unit destined for FBA.

Receive inbound

Containers clear the Port of Long Beach and arrive at our dock within hours. Floor-loaded or palletized containers are unloaded and staged for prep within 24 hours.

Inspect & verify

Every shipment is verified against your PO. SKUs counted, condition inspected, expiry dates checked, lot codes recorded. Damaged units flagged before they enter Amazon's network and trigger compliance penalties.

FNSKU labeling

Every unit gets an FNSKU barcode label printed at our facility. Labels are properly positioned to be scannable at Amazon's receiving stations. Critical for FBA receiving accuracy.

Prep services per Amazon requirements

Polybagging for soft goods, suffocation warnings, bubble wrap for fragile, double-boxing for sets, bundling for multipacks, expiry labels for consumables, hazmat documentation for regulated categories.

Palletization & shipment building

Units organized by SKU, palletized to Amazon spec, stretch-wrapped, labeled with shipment IDs. SPD (small parcel) or LTL pallets routed by your strategy.

ASN & shipment tender

ASN transmitted to Amazon Seller Central. Pallets tendered to your designated carrier or Amazon Partnered Carrier (UPS LTL). Tracking confirmation emailed.

Why Matrix

Why LA-based FBA prep wins for most brands.

If your inventory comes from Asia, every day saved in inbound transit is a day earlier you start selling on Amazon. LA-based prep is structurally faster than East Coast or Midwest prep.

Port of Long Beach in minutes

Our facility is within drayage range of the Port of Long Beach and Port of Los Angeles. Containers can clear customs and arrive at our dock the same day. East Coast prep services need 5-7 days of cross-country drayage first.

Multi-format prep capability

Polybag, suffocation labels, bubble wrap, fragile labels, multi-packs, kit assembly, hazmat documentation, expiry dating, lot tracking — every requirement Amazon imposes is supported.

Hazmat-trained team

Lithium batteries, aerosols, magnetized items, regulated supplements — all handled by trained staff with proper UN-rated packaging on-site.

Per-unit transparent pricing

Standard prep services have fixed per-unit pricing. No hidden fees, no surprise charges, no "premium prep" tier markup. Every line item appears on the invoice.

ASN compliance built in

Amazon penalizes shipments without proper ASN transmission. Our WMS generates and transmits ASN to Seller Central automatically, in the correct format, with correct timing.

Mixed FBA + FBM workflow

Same inventory pool serves both FBA prep (shipped to Amazon warehouses) and FBM (shipped direct to Amazon customers from our dock). One operation, both channels.

Who it's for

Who FBA prep at Matrix is built for.

Brands importing from Asia for sale on Amazon

The default high-conviction case. LA port proximity is a structural advantage for Asia-sourced FBA inventory.

Brands launching new SKUs on Amazon

First-time FBA inbound needs to be perfect — Amazon's penalties for non-compliance get expensive fast. We handle first-launch inbound with extra inspection rigor.

Brands switching from in-house FBA prep

If you've been polybagging and FNSKU-labeling in a garage, switching to a prep service typically frees 20-40 hours per week of founder time.

Brands running FBA + FBM in parallel

Some SKUs go to FBA (high velocity, FBA-economic), others go FBM (oversize, hazmat, low velocity). One inventory pool, two channel workflows.

Brands with hazmat or restricted SKUs

Lithium battery products, aerosols, magnetized items, certain supplements — all categories with restrictions. We have the compliance experience and the certified packaging.

Brands selling on Amazon plus other channels

Most modern brands don't sell only on Amazon. Multi-channel operation with FBA as one of many — fully supported, same inventory.

FAQ
What does FBA prep actually cost?
Pricing depends on which prep services you need. Simple FNSKU labeling is around $0.50/unit. Polybagging adds $0.15-$0.25/unit. Bundling or kit assembly ranges $0.40-$1.00/unit depending on complexity. We send an itemized quote based on your specific SKU mix.
How do FBA prep services differ from FBA itself?
FBA prep happens before your inventory enters Amazon's warehouses. We prep your units (label, polybag, bundle, etc.) and ship them to Amazon. FBA itself is Amazon picking, packing, and shipping orders to customers from their network. Both can be needed.
Can you handle hazmat SKUs?
Yes. Lithium batteries, aerosols, magnetized items, regulated supplements, and most other hazmat categories are handled with proper documentation, packaging, and labeling. Hazmat carries additional per-unit fees.
How fast can you turn around an FBA inbound shipment?
Standard turnaround is 48-72 hours from container arrival to shipment building completion. Urgent prep can be expedited for an additional fee.
Do you handle Amazon SFP (Seller-Fulfilled Prime)?
Yes. SFP requires same-day pick-pack-ship under Amazon's Prime SLAs. Our 2 PM Pacific cutoff and same-day shipping operation supports SFP.
Can you do FBA prep for products I don't sell on Amazon yet?
Yes. We frequently prep inventory for brand launches before the listing is live. SKU data needs to be confirmed before we can label.
