Amazon FBA & Walmart WFS Prep for Indian Sellers - What Actually Happens to Your Inventory
Amazon rejects Indian sellers' shipments over labels, polybags and case-pack rules. What FBA and Walmart WFS prep actually involves, and how a US 3PL handles it.

Most Indian sellers who fail on Amazon US don't fail because of their product. They fail at the loading dock.
A shipment leaves Tiruppur or Jaipur or Coimbatore, clears customs, arrives at an Amazon fulfilment centre - and gets refused. Wrong barcode. No polybag. Suffocation warning missing. Case pack labelled as individual units. Amazon either charges an "unplanned prep" fee per unit, or bounces the whole shipment back to a US address you don't have.
We wrote earlier about why Indian businesses need a US 3PL at all - the strategic case for holding stock inside America. This article is the operational half: what prep actually means, why it is where first-time exporters lose money, and what happens to a carton between the port and the customer.
"Prep" is not packing. It is compliance.
Prep is the set of physical requirements a marketplace imposes before it will accept your inventory into its network. Amazon and Walmart both publish them, both enforce them automatically, and neither will make an exception because you're new.
The requirements that catch Indian sellers most often:
Barcodes. Every unit needs a scannable FNSKU (Amazon) or GTIN/UPC (Walmart). A barcode printed in India that smudges, sits under a seam, or duplicates an existing ASIN gets the unit quarantined. Manufacturer barcodes must often be covered entirely.
Polybagging. Any soft goods - apparel, textiles, home linen, which is a huge share of Indian exports - must be poly-bagged with a suffocation warning printed at a specified minimum size. Bags over a certain opening need the warning; bags without it are non-compliant even if the product is perfect.
Case-pack and box configuration. Amazon distinguishes between individual units and case packs, and mislabelling one as the other is one of the most common and most expensive errors. Box weight and dimension limits are hard limits.
Expiry and lot coding. Anything consumable - spices, ayurvedic products, cosmetics, food - needs date formatting exactly as specified, and often a minimum remaining shelf life on arrival.
Fragility and bundling. Multi-piece sets must be bundled so they cannot separate in the network. Glass and ceramics need specified protection.
None of this is difficult. All of it is unforgiving. And it is nearly impossible to get right from 13,000 km away, because the feedback loop is a rejected shipment three weeks later.
What a US prep partner actually does with your carton
This is the part sellers rarely see described concretely. Using Prijana Fulfillment - a Pennsylvania LLC running a 2,300 sq ft facility in Chester County, PA - as the worked example, here is the sequence:
1. Inbound receiving. Your sea or air shipment arrives as parcels or pallets. Every unit is counted against your packing list, inspected for transit damage, and logged into your dashboard the same day it lands. Discrepancies get flagged immediately - while you can still raise it with your manufacturer, not six weeks later when stock runs short.
2. Inspection and quarantine. Damaged, mislabelled, or short-shipped units are separated before they contaminate a marketplace shipment. One bad unit entering FBA can trigger a listing-level performance hit; catching it at receiving is enormously cheaper.
3. Prep proper. FNSKU labelling, polybagging with compliant suffocation warnings, bundling, relabeling, repackaging, and kitting - multi-packs, subscription boxes, custom sets - built to your written specification.
4. Forwarding to FBA or WFS. Prepped inventory ships to the fulfilment centres Amazon or Walmart assigns, in their required box configuration, with their shipment plan attached.
5. Or fulfil it yourself. Not everything should go to FBA. Orders from your own Shopify store, wholesale B2B orders, and slow-moving SKUs are often better shipped direct from the 3PL - picked, packed and dispatched same business day, to all 50 states, at whatever carrier rate is best that day. Shopify, Walmart and Easyship sync automatically, so there's no manual order entry.
6. Returns. US returns come back to the US warehouse, get inspected, then restocked or quarantined per your instructions. This matters more than sellers expect: return handling is a direct input to your Amazon and Walmart account health metrics.
The hybrid model most sellers should actually run
The instinct is to send everything to FBA. That is usually wrong for a new Indian seller, for one blunt reason: FBA storage fees punish slow movers, and you do not yet know which of your SKUs are slow movers.
A more sensible first year looks like this:
- Your proven SKUs go to FBA/WFS. Prime badge, marketplace-native conversion, Amazon handles delivery.
- Everything untested stays at the 3PL. You pay per order, not per cubic foot per month. If a SKU flops you have not paid long-term storage on it, and you can liquidate or re-kit it without an FBA removal order.
- Your own website and B2B orders ship from the 3PL. Better margin, your branding on the box, and no marketplace commission.
You need one inventory pool in the US to do this. That is the entire argument for a prep-and-fulfilment partner rather than sending containers straight to Amazon.
What it costs you to get this wrong
Concretely, the failure modes and their price:
| Mistake | What it costs |
|---|---|
| Missing/unscannable FNSKU | Per-unit unplanned prep fee, or shipment refused |
| No suffocation warning on soft goods | Non-compliant; units held |
| Case pack mislabelled as individual units | Receiving discrepancy, inventory lost in reconciliation |
| Shipping everything to FBA | Long-term storage fees on unproven SKUs |
| No US returns address | Returns abandoned; account health degrades |
Every one of these is avoidable with a US receiving point and someone checking the carton before Amazon does.
Getting started, realistically
The honest first step is a conversation, not a container. Prijana runs a free 15-minute call where you describe what you sell, your volumes, and your intended US channels, and get a written cost breakdown back within 24 hours. Onboarding runs about 48 hours. They currently waive the setup fee for their first cohort of sellers - worth asking whether that still applies when you call.
Practical things to have ready for that call:
- What you sell, and whether it is soft goods, consumable, fragile, or none of those
- Realistic monthly order volume, and your best guess at your top 3 SKUs
- Which channels you intend to sell on - Amazon, Walmart, your own Shopify store, or wholesale
- Whether you already have a US entity, or are exporting as an Indian company
- Your target launch month
Support is available in Tamil and English, which removes a genuine friction point for South Indian exporters.
Frequently asked questions
Q: Do I need a US company to use FBA prep?
Not always. Many Indian sellers operate as exporters selling into the US, though the answer depends on your channel and how you handle sales tax. Raise it on the first call - it changes your setup.
Q: Can I send stock straight from my factory to Amazon and skip the 3PL?
You can, and Amazon will apply unplanned-prep charges for anything non-compliant - assuming they accept the shipment at all. Sellers usually try this once.
Q: What is the difference between FBA prep and fulfilment?
Prep gets your inventory compliant and into Amazon's network. Fulfilment means the 3PL ships orders to your customers directly. Most sellers need both, for different SKUs.
Q: How fast do orders ship?
Same business day is the dispatch target for orders fulfilled from the warehouse, shipping to all 50 states.
Q: How do I get a quote?
