FBA prep services: the 2026 taxonomy.
An Amazon FBA prep center offers some subset of 17 services grouped into 3 tiers: Core (5), Adjacent (7), Advanced (5). Per-unit pricing, decision rules, and named entities on each. Use this as a checklist when comparing centers.
Amazon discontinued its in-house FBA prep service for shipments after January 1, 2026 (Supply Chain Dive). Every service below is third-party only.
The 5 services every Amazon FBA shipment touches.
Core services are required by Amazon policy or by federal regulation. A prep center that does not offer these is not a prep center. Every center in our directory offers all 5.
01FNSKU labeling
Apply Amazon's Fulfillment Network Stock Keeping Unit barcode to every unit. Required for stickered (non-commingled) inventory. The FNSKU must cover any visible manufacturer barcode.
Do I need it? Required for every FBA shipment unless your inventory is commingled. Most sellers opt into stickered inventory to protect their listings, which means FNSKU on every unit.
02Polybagging
Bag soft goods (apparel, textiles) and any unit at leak risk in a 1.5 mil minimum, transparent polybag. Bags with an opening 5 inches or larger require a printed suffocation warning.
Do I need it? Required for apparel, textiles, plush, and any item that could leak, shed, or be contaminated. Skipping it triggers Amazon unplanned-service fees.
03Bubble wrap
Wrap fragile items in bubble wrap before boxing. Required by category policy for glass, ceramic, electronics, and any unit at impact risk. Not optional.
Do I need it? Required for fragile categories. Amazon may apply the wrap and bill you per unit if your shipment arrives without it.
04Expiration-date scanning
Scan and record expiration dates on every unit of consumable inventory. Required for food, supplements, cosmetics. Amazon requires a minimum 90 days remaining at receipt for most categories.
Do I need it? Required for consumables. Without it, Amazon flags units as stranded inventory if they arrive within the disqualifying window.
05Hazmat documentation
Prepare Safety Data Sheets and DOT PHMSA paperwork for batteries, aerosols, lithium-ion, and other hazardous materials. Required by federal regulation, not just Amazon policy.
Do I need it? Required for any product containing lithium-ion, alkaline at certain quantities, aerosols, pressurized containers, or DOT-regulated materials. Self-prep is legally risky without DOT training.
The 7 services where prep centers differentiate.
Adjacent services overlap with light 3PL work (kitting, returns, multi-channel) and value-added prep (inspection, photo logs). Most directory centers offer 4 to 6 of these.
01Bundling
Group multiple units into a single FBA-shippable bundle (multipack). Common for replenishment SKUs and category-specific bundles like 3-pack supplements or 2-pack accessories.
Do I need it? Useful if you sell multipacks as a distinct ASIN, run promotional bundles, or want to consolidate inventory units to reduce per-unit FBA fees.
02Kitting
Assemble a single SKU from multiple component parts. Different from bundling because the components are not separately sellable. Common for gift sets, starter kits, and component-based products.
Do I need it? Required if your product is sold as a kit but received from suppliers as separate components. Saves on FBA inbound fees vs shipping component-by-component.
03Inspection on receipt
Open and check every box on receipt for damage, count accuracy, and prep-fitness. Photographs flagged units. Mid-tier and premium centers do this as standard practice.
Do I need it? Strongly recommended above 1,000 units per shipment. Catches supplier errors (mislabeled, wrong-quantity, damaged) before Amazon does and charges you for it.
04Multi-channel fulfillment (MCF)
Pick, pack, and ship orders from non-Amazon channels (Walmart, Shopify, TikTok Shop, eBay) out of the same inventory pool. Crosses into 3PL territory.
Do I need it? Required if you sell on more than one channel and want one operator handling all of it. Pure prep centers usually do not offer this; full 3PLs do. See our 3PL recommendations page.
05Receiving
Accept inbound shipments from your supplier, sign the BOL, unload, and confirm count. Billed per pallet, per carton, or per unit depending on the prep center.
Do I need it? Required for any third-party prep workflow. The fee structure (pallet vs carton vs unit) is a major source of variability across prep centers.
06Photo damage logs
Photograph damaged units on receipt and provide time-stamped logs. Used for supplier claims and Amazon dispute resolution.
Do I need it? Recommended if you import from China or run a supplier audit program. Insurance claims and supplier disputes need documentary evidence; this is it.
07Returns processing
Receive FBA removal orders, FBM customer returns, or DTC returns from non-Amazon channels. Inspect, relabel, repackage, then re-FBA or dispose. Three distinct workflows at three different price points.
Do I need it? Required if you have an active returns recovery program. FBA returns alone justify it above 2% return rate; multi-channel sellers usually outsource it by default.
The 5 services that mark a high-end operator.
Advanced services are required at scale or for regulated categories. Few centers offer all 5. Required only for FDA-regulated categories, hazmat at volume, and operators above 5,000 units per month.
01API and SFTP integration
Programmatic access to inventory, inbound, and order data via REST API or SFTP. Direct integrations with ShipStation, Veeqo, SellerCloud, ShipHero, or Linnworks.
Do I need it? Required above 5,000 units per month. Email-and-spreadsheet workflows do not scale. A prep center that cannot expose inventory data programmatically cannot serve a 7-figure FBA operation.
02Real-time visibility dashboard
Live dashboard for inbound status, shipment progress, damage logs, and per-shipment notifications via Slack, email, or webhook. Visibility lag over 24 hours is a red flag at scale.
Do I need it? Required for any operation where inventory visibility drives buying decisions. Cooperative replenishment models and JIT-style ops cannot function with weekly spreadsheet updates.
03FDA-registered facility
Prep center operates a facility registered with the US Food and Drug Administration. Required for handling food, dietary supplements, cosmetics, and medical devices.
Do I need it? Required if your category falls under FDA jurisdiction. Self-prep is generally not allowed for FDA-regulated products at scale; use a registered facility.
04DOT-certified hazmat handling
Prep center holds Department of Transportation hazmat handling certification (DOT 49 CFR 172.704). Required for shipping lithium-ion, aerosols, and other regulated hazardous materials.
Do I need it? Required for any battery, aerosol, or pressurized product. Non-certified centers refuse hazmat. Verify certification at booking.
05Scan-and-verify QA
QA step where the prep center scans the FNSKU barcode and the unit's inner barcode and flags any mismatch. Detects mis-labeled inventory before shipment.
Do I need it? Strongly recommended on every shipment over 500 units. Mis-applied FNSKU at scale is the single most expensive prep failure; scan-and-verify is the only reliable defense.
How many services do real prep centers offer?
Most prep centers in our directory offer between 5 and 12 of the 17 services on this page. Specialists run lean (5 to 7 services, deep on quality). Platform-style centers offer 10 plus services but with more variability in execution.
When evaluating, count the services that match your product needs, not the total. A center that offers all 17 but is weak on hazmat is the wrong choice for a battery SKU. A center that offers only 7 but does FDA-registered supplements correctly is the right choice for a vitamin line.
Common FBA prep service questions.
- What services do FBA prep centers offer?
- Most third-party prep centers offer 5 to 12 services from a 17-item taxonomy. The 5 core services (FNSKU labeling, polybagging, bubble wrap, expiration scanning, hazmat docs) are table stakes. The 7 adjacent services (bundling, kitting, inspection, multi-channel fulfillment, receiving, photo logs, returns) are where centers differentiate. The 5 advanced services (API, real-time visibility, FDA, DOT, scan-and-verify QA) signal a high-end operator. Verified 2026-05-14.
- Does Amazon still offer its own FBA prep service?
- No. Amazon discontinued its in-house FBA Prep & Item Labeling service for shipments after January 1, 2026 (source: Supply Chain Dive, October 2024). All prep services on this page are third-party only.
- How much do FBA prep services cost per unit?
- Budget tier (FNSKU plus polybag) runs $0.65 to $2.50 per unit. Mid tier (with bundling, inspection, expiration scan) runs $2.50 to $5.00 per unit. Premium tier (with hazmat, FDA, photography, fast SLAs) runs $5.00 to $15.00 per unit. See per-service price bands on this page and the full pricing page for tier breakdowns.
- What is the difference between FBA prep and 3PL fulfillment?
- A prep center receives, preps, and forwards inbound shipments to Amazon. A 3PL holds inventory long-term, fulfills multi-channel orders (Shopify, Walmart, eBay), processes returns, and integrates via API. Prep-only is cheaper per unit; 3PL is broader. The line is operational scope, not a strict taxonomy.
- Do I need hazmat prep for my product?
- Required if your product contains lithium-ion batteries, alkaline batteries in regulated quantities, aerosols, pressurized containers, or DOT-regulated materials. Self-prep is legally risky without DOT 49 CFR 172.704 training. Use a DOT-certified prep center.
- What is kitting? When do I need it?
- Kitting assembles a single sellable SKU from multiple component parts (e.g., a gift set with 3 components). Different from bundling, where each component is independently sellable. Required if your supplier ships components separately but you sell them as one ASIN.
- Can a prep center do multi-channel fulfillment for Walmart and Shopify?
- Some can; many cannot. Pure prep centers forward to Amazon FCs and do not fulfill orders to end customers. 3PLs do. If you sell on Walmart WFS, Shopify DTC, or eBay alongside FBA, look for a prep center that explicitly offers multi-channel fulfillment, or use a 3PL.
- What is FNSKU labeling and why is it required?
- FNSKU is Amazon's Fulfillment Network Stock Keeping Unit barcode, unique to each seller-ASIN pair. Required on every unit of stickered (non-commingled) inventory so Amazon's FCs can track your specific inventory separately from other sellers' identical ASINs. Without it, your inventory could be commingled or trigger unplanned-service fees.
