From Prep to Profit Meeting Amazon FBA Requirements

Selling on Amazon using the FBA (Fulfillment by Amazon) model offers an incredible opportunity: you tap into Amazon’s logistics network, Prime-eligible shipping, customer trust and global reach.
However, success isn’t automatic. There are strict requirements, evolving policies, fees and risks. Without proper compliance and operational control, many sellers see their profits eroded, face inventory issues or even account suspensions.

That’s where a specialised 3PL partner like Max 3PL can make a big difference. By handling prep, warehousing, inbound logistics, and analysis of Amazon’s policies, Max 3PL helps you stay compliant and focused on the parts of the business you do best: product selection, marketing and growth.

In this guide we’ll walk you through all the major Amazon FBA requirements in 2025, highlight key pain‐points sellers face, and explain how Max 3PL can support you at each step.

Seller Account & Eligibility Requirements

Before you even send inventory to Amazon or your 3PL, you must ensure your seller account is properly set up, and you’re eligible for FBA.

1.1 Choosing the Right Seller Plan

When you register on Seller Central, Amazon offers different plan types (e.g., Individual vs Professional). Choosing the right plan depends on your expected volume.

1.2 Account Registration & Verification

Amazon requires sellers to provide accurate business information, identity verification, and banking/tax details. For example:

Valid government-issued photo ID.
Proof of address (usually within the last 180 days) matching business registration.
Bank account and routing information so Amazon can deposit sales proceeds.
Tax identification number (SSN/EIN for US, or applicable local tax ID for non-US sellers).

Failing to submit correct documentation can delay account approval.

1.3 FBA Enrollment & Product Eligibility

Once your account is live, you must enroll in FBA (or have inventory at Amazon’s fulfilment centres) and ensure your products meet Amazon’s eligibility requirements. Not all categories are open to FBA or to all sellers. Some require special approval.

Key things to consider:

Are your products allowed for FBA (size, weight, condition)?
Are you the brand owner, or do you have authorization?
Are there product restrictions (hazardous materials, regulated items, etc.)?

1.4 Account Health & Performance Metrics

Amazon closely monitors seller performance: order defect rate, late shipment rate, cancellation rate, inventory health, etc. Poor metrics can reduce your ability to send inventory or even lead to account suspension.

A 3PL partner like Max 3PL can help you manage these metrics by ensuring inventory flows smoothly, shipments arrive on time, and logistics errors are minimised.

Product, Compliance & Listing Requirements

With your account set up, the next layer is ensuring your products and listings comply with Amazon’s rules.

2.1 Listing Accuracy & Condition Guidelines

When you list on Amazon, you must correctly categorise product condition (“New”, “Used”, etc.), provide truthful descriptions, and avoid misleading claims. Amazon’s policies emphasise accuracy to protect customers.

2.2 Product Restrictions & Safety Requirements

Certain product types are restricted or require additional approval:

Regulated items e.g., hazardous materials, medical devices, etc.
Products must meet all local regulatory standards (e.g., CE marking for EU, FCC for US) as applicable.
Listings should specify correct compliance information, warnings, and instructions.

If you’re in categories requiring special prep or packaging, using a 3PL like Max 3PL ensures that your products meet Amazon’s requirements before they reach Amazon warehouses.

2.3 Packaging, Labelling & Preparation

One of the most frequent causes of delays or rejects is inbound shipping non-compliance: incorrect labels, improper packaging, missing information. Amazon provides detailed guidelines for FBA prep. For instance, from January 1, 2026 Amazon will no longer offer prep and item labelling services for US-based FBA shipments.

You should ensure:

Each unit has a valid barcode (UPC/EAN) or Amazon FNSKU label.
Packaging protects product integrity and shipping viability.
Pallets, boxes or shipping units meet Amazon’s size, weight and palletisation rules.
Items are organised so that Amazon can process them efficiently.

Max 3PL can prep, label, inspect, and forward your inventory correctly so you avoid Amazon inbound rejections or penalties.

Inbound Shipping, Warehousing & Fulfilment Requirements

The mechanics of shipping inventory to Amazon or to a staging 3PL facility are critical. Errors here can cost time, money and rank.

3.1 Shipment Planning & “Send to Amazon” Process

When you want to send inventory to Amazon’s fulfilment centres, you must create a shipment plan in Seller Central, designate the sending fulfilment centres, and provide all required details. Some recent capacity changes impact this process (more below).

Key steps:

Create a shipment in Seller Central (select products, quantity, warehouse).
Prep and label inventory appropriately.
Choose carrier and shipping mode.
Track shipment and ensure it arrives within expected time.

If you leverage Max 3PL, the inbound shipping coordination can be outsourced: Max 3PL receives inventory from your supplier, preps it, and then either forwards to Amazon or warehoused for you.

3.2 Amazon FBA Capacity & Storage Limits

An important requirement for FBA is understanding how much inventory Amazon will accept and store. For June–July 2025, Amazon capped FBA capacity to about 5 months of expected sales volume, down from approximately 6 months previously.

Important implications:

If you send too much inventory, Amazon may reject new shipments.
Space is allocated based on your performance metrics (for example, Inventory Performance Index, IPI) and sales velocity.
Slow-moving inventory can reduce your capacity allocation.

A 3PL partner like Max 3PL allows you to store “overflow” inventory off-site (not in Amazon’s fulfilment centres) and then replenish Amazon stock in smaller, controlled shipments — reducing risk of capacity-based rejection and high storage fees.

3.3 Storage Fees, Long-Term Storage Risk & Removal Orders

Even when Amazon accepts your inventory, you must pay storage fees, and risks of long-term storage assessments exist. If inventory remains unsold for a long time, Amazon may charge higher fees or require removal. Proper inventory planning is essential.

With Max 3PL you can monitor stock-age, decide when to remove, redeploy, or liquidate inventory more flexibly and avoid Amazon’s penalties.

3.4 Multi-Channel Fulfilment & Hybrid Models

Many sellers adopt a hybrid model: keep best-selling SKUs in Amazon FBA, store slower-moving or large items at a 3PL. They may fulfil orders from other channels (own website, Walmart, Shopify) via the 3PL rather than relying entirely on Amazon. This diversification helps manage risk and control costs.

Max 3PL supports multi-channel fulfilment, enabling you to send inventory where it’s needed, maintain faster shipping, and avoid being locked solely into Amazon’s ecosystem.

Cost, Fee Structure & Profitability Requirements

Running FBA isn’t just about sending inventory and watching sales. You must understand and manage the cost side thoroughly. Many sellers overlook hidden costs and reduce profitability.

4.1 Amazon Fees & Changes in 2025

Amazon updates its fee structures periodically. For example: as of January 15, 2025, FBA fulfilment fees reverted to non-peak-period rates (unchanged from 2024).

Important cost components:

Fulfilment fees per unit (based on size/weight tiers)
Monthly storage fees (based on cubic volume)
Long-term storage fees (for inventory older than specified thresholds)
Inbound fees or prep fees (if you use Amazon’s optional services)
Removal fees or disposal fees (if you remove inventory)

4.2 Profitability Considerations

To remain profitable, you must factor in:

Product cost (manufacturing or purchase)
Shipping cost to 3PL or Amazon
Prep/labeling cost
Storage fees
Amazon fulfilment fees
Returns cost and potential disposal cost

Without careful planning, fees can erode margins. Recent commentary from sellers highlights this:

“Yes, but it’s not nearly as easy or cheap to sell.”

4.3 How Max 3PL Helps Control Costs

Optimised warehousing: By storing excess inventory in a 3PL (rather than Amazon), you often get lower storage fees and more flexibility.
Just-in-time forwarding: By forwarding only the inventory Amazon needs, you minimise storage age and reduce long-term storage penalties.
Prep & labelling efficiency: Max 3PL ensures inbound shipments are correct in one go — fewer rejections means fewer extra costs.
Multi-channel fulfilment: Use Amazon for fast-moving SKUs, 3PL for slower or bulk — diversify cost structure.
Data & forecasting support: With accurate inventory and performance data, you avoid over-stocking or under-stocking, thereby protecting margins.

Best Practices & Compliance Checklist for Sellers

Here’s a practical checklist and set of best practices to ensure you meet Amazon FBA requirements and keep your business operating smoothly.

Checklist:

Choose the correct Amazon selling plan (individual vs professional).
Register your Seller Central account with accurate, verified info.
Provide all required documents (ID, address, bank, tax ID).
Enroll in FBA and verify product category eligibility.
Ensure product compliance (safety, regulations, category restrictions).
Build accurate, high-quality product listings (title, images, description).
Prep products with correct packaging, labelling, barcodes (FNSKU/UPC).
Create shipment plans and coordinate inbound logistics.
Monitor Amazon’s capacity limits, storage fees and restock policies.
Monitor account metrics (IPI, defect rate, cancellations, returns).
Analyze cost structure (product cost + shipping + fees) and maintain margin.
Use a 3PL (like Max 3PL) for overflow inventory, prep services, multi-channel fulfilment.
Periodically review performance, remove/redirect slow stock, optimise SKUs.

Best Practices:

Forecast demand realistically: Avoid sending large volumes into Amazon unless you’re confident in sell-through rate and capacity allowance.
Rotate inventory proactively: Slow-moving items should be removed or redirected early to avoid long-term storage fees.
Keep UPC/FNSKU and listing details consistent: Mismatches lead to stranded inventory and fulfilment delays.
Maintain high account health: Customer experience matters — Amazon will penalise poor performance.
Diversify your fulfilment model: Don’t rely solely on FBA. Use 3PL and other channels to reduce risk.
Track your true cost per unit: Regularly update your margin calculations and factor in all hidden fees.
Stay up-to-date on policy changes: Amazon frequently updates rules, capacity limits and fee structures. For example: restock limits introduced in 2025.
Partner with a capable 3PL: Choose one with Amazon prep experience, multi-channel capability, reporting dashboards and good communication (Max 3PL offers these).

How Max 3PL Specifically Supports Amazon Sellers

Let’s dive into how Max 3PL supports your Amazon FBA business at each stage.

6.1 Receiving & Warehousing

Max 3PL receives inventory from your supplier/manufacturer, checks for quality, counts units, and stores them in a climate-controlled facility. This helps you hold bulk inventory without paying high Amazon long-term storage fees.

6.2 Amazon FBA Prep & Labelling

Max 3PL performs all required prep work: labelling units with Amazon FNSKU, ensuring packaging meets Amazon’s requirements, bundling or kitting if needed. Given that Amazon stops offering prep & labelling services for US FBA shipments from Jan 1 2026, this service becomes even more critical.

6.3 Inbound Logistics to Amazon

Max 3PL coordinates shipments to Amazon fulfilment centres: creating shipping plans, managing carrier coordination, ensuring correct documentation and labelling to avoid Amazon inbound rejections.

6.4 Inventory Age & Rotation Management

By storing bulk inventory off-site, Max 3PL allows you to release to Amazon only when needed, controlling inventory age and avoiding costly long-term storage fees or capacity blocks.

6.5 Multi-Channel Fulfilment

If you sell via other channels (your website, Shopify, Walmart, etc.), Max 3PL can fulfil those orders too. You maintain control of your brand, reduce reliance on Amazon, and optimise shipping cost.

6.6 Reporting & Data

Max 3PL provides dashboards with inventory levels, age, shipment status, cost breakdowns and forecasting support. This gives you the data to make better decisions and maintain compliance and profitability.

6.7 Cost Optimisation

Through proper prep, packaging optimisation, smart inbound scheduling and inventory rotation, Max 3PL helps you minimise unnecessary fees and make your Amazon FBA operations more efficient.

Case Study & Example Workflow

Imagine you’re launching a private-label product (say a compact home accessory) and you’re using Amazon FBA plus Max 3PL.

You source the product, decide on SKU, packaging, etc.
You register your Amazon seller account, submit all documents and enrol in FBA.
You send a large batch of inventory to Max 3PL’s warehouse rather than directly to Amazon.
At Max 3PL: inventory is checked, labelled with FNSKU, packed in Amazon-compliant packaging.
You instruct Max 3PL to generate smaller shipments to Amazon’s fulfilment centres timed for when you expect demand spikes (avoiding storage from sitting too long).
Your listing is live on Amazon, you monitor metrics (sell-through, IPI, capacity), and ensure you aren’t sending too much or getting restricted.
Slow-moving stock stays at Max 3PL’s warehouse until you decide to move it elsewhere (e.g., fulfil via your website) or run inventory liquidation.
You carefully monitor costs: product cost + inbound to Max 3PL + prep + shipping to Amazon + Amazon’s fees + storage + removal. Margins are calculated and kept healthy.
Based on Max 3PL’s data, you adjust your inventory strategy, scale successful SKUs, drop weak ones, and utilize the multi-channel fulfilment to diversify revenue streams.
Over time your brand grows, you control fulfilment risk, minimise over-storage fees, maintain high Amazon account health and scale profitably.

This workflow illustrates how the FBA requirements combine with a 3PL strategy to keep you compliant and scalable.

Challenges & How To Overcome Them

Even with a good partner and knowledge, sellers face challenges. Here are common ones and how to mitigate them.

8.1 Inventory Capacity Restrictions

As discussed, Amazon has tightened capacity limits (5 months of sales volume for June–July 2025) and re-introduced restock limits per ASIN.
Solution: Use 3PL warehousing for overflow inventory. Ship to Amazon in smaller increments. Focus on fast-moving SKUs first.

8.2 Rising Fees & Fee Complexity

Many sellers report FBA fees are higher or harder to control than before.
Solution: Build a full cost model including every fee line. Use 3PL for storage or fulfilment of high-cost items. Optimize packaging and shipping to reduce weight/size.

8.3 Compliance Errors & Rejections

Wrong labelling, incomplete prep, or non-compliance with Amazon packaging rules cause inbound issues.
Solution: Use a 3PL that specialises in Amazon prep (Max 3PL). Maintain checklists, audit shipments before sending.

8.4 Slow-Moving Inventory & Storage Fees

Inventory that sits too long in Amazon fulfilment centres triggers long-term storage fees or gets stranded.
Solution: Monitor inventory age, run promotions or use removal/redistribution. Use 3PL storage as buffer.

8.5 Increased Competition & Saturation

While FBA is still viable, many sellers note increased competition and reduced margins.
Solution: Focus on differentiation, niche branding, higher-margin products. Use analytics (via 3PL dashboards) to scale wisely rather than blasting low-margin commodities.

Future Trends & What Sellers Should Watch

As you plan ahead, be mindful of evolving requirements and strategic shifts.

Amazon may further limit capacity or increase fees for slow-moving stock.
Amazon’s policies around prep, labelling and third-party partners will continue to tighten (e.g., Amazon ceasing its own prep services in US in 2026).
Sellers will increasingly adopt hybrid fulfilment models (FBA + 3PL + FBM) to manage cost and risk.
Data and technology (dashboards, forecasting, automation) will differentiate winners.
International selling and cross-border logistics require compliance with local regulations (e.g., for sellers outside US shipping in)

By aligning with a 3PL partner that stays ahead of these changes (Max 3PL for example), you’re more likely to stay compliant, agile and profitable.

Summary & Action Plan

To wrap up:

Amazon FBA offers major benefits but brings major requirements (account setup, product compliance, listing accuracy, prep/label rules, shipping logistics, storage/fee control).
In 2025, the environment is tougher: tighter capacity limits, higher fees, increased competition.
A strong 3PL partner like Max 3PL provides critical support: warehousing, Amazon‐compliant prep, flexible stock storage, multi-channel fulfilment and data analytics.
To succeed you must actively manage: your costs, inventory age, Amazon metrics, compliance and growth strategy.
Use a hybrid fulfilment model (FBA + 3PL + other channels) to gain flexibility, reduce risk and improve profitability.

Action plan for you today:

Review your current Amazon seller account: Are all documents verified? Are you enrolled in FBA properly?
Audit your product listings: Are they accurate? Are they eligible for FBA? Are there compliance or category risks?
Analyse your inventory: Which SKUs sell fast? Which are slow? How many months of inventory do you have at Amazon?
Build your cost model: Product cost + shipping + 3PL or Amazon fees + storage + removal. What is your margin?
Evaluate your fulfilment strategy: Could you benefit from using Max 3PL for overflow, prep or multi-channel fulfilment?
Set tracker metrics: monthly sell-through, IPI score, inventory age, inbound shipping accuracy, return rate.
Plan your next shipment: How much to send to Amazon? How much to store at your 3PL? What packaging/labelling steps are needed?

By proactively following these steps, you’ll be better positioned to meet Amazon FBA requirements, avoid costly mistakes and scale sustainably.
