Selling on Amazon USA as a UK-based FBA seller opens up access to one of the largest and most profitable e-commerce markets in the world. Amazon USA generates significantly higher revenue per seller than Amazon UK and many product categories on the US marketplace have stronger demand better margins and less competition than their UK equivalents. But approaching USA wholesale suppliers from the UK comes with a specific set of challenges that UK-only sellers never face — and understanding how to navigate each one is the difference between successfully building a cross-Atlantic wholesale business and giving up at the first hurdle.

We are Brandhunterz Ltd — a UK registered wholesale sourcing company (Company No: 15342697) — and in this complete guide we cover exactly how UK Amazon FBA sellers should approach USA wholesale suppliers what structural differences to be aware of how to handle the logistics of sourcing from the USA and the specific outreach strategy that gets UK sellers approved by American brands.

Why UK Sellers Should Consider Sourcing From USA Suppliers

Before covering how to approach USA suppliers it is worth understanding why the US market is worth the additional complexity. These are the key advantages that make Amazon USA a compelling opportunity for UK wholesale sellers who are ready to expand:

Amazon USA Advantage	What It Means for UK Wholesale Sellers
Significantly larger customer base	US Amazon has over 150 million Prime members — UK has approximately 15 million
Higher average selling prices	Many products sell at higher USD prices than their GBP equivalents on Amazon UK
Access to US-only brands	Thousands of strong US brands with no UK competition — untapped opportunity
Less seller competition on many ASINs	Some US listings have fewer FBA sellers than UK equivalents — better Buy Box share
Dollar-denominated revenue	USD revenue diversifies your currency exposure alongside GBP earnings

What You Need Before Approaching USA Suppliers

Before contacting any US wholesale supplier you must have the correct business and logistical infrastructure in place. Without these foundations US suppliers will not open a trade account for you — and even if they did you would have no way to receive or forward your stock to Amazon FBA USA warehouses.

Requirement	What It Is	Essential
Amazon USA Professional Seller account	Separate to your UK account — register at sellercentral.amazon.com	Yes
EIN — Employer Identification Number	US tax ID required by most suppliers and Amazon USA — apply free via IRS website	Yes
US prep centre or freight forwarder	US-based facility that receives your stock inspects and forwards it to FBA warehouses	Yes
US business mailing address	Your prep centre address — used as your delivery address on all supplier accounts	Yes
US business bank account or Wise account	For paying US suppliers in USD — Wise or Airwallex provide cost-effective USD accounts for UK businesses	Yes
UK Limited Company registration	Your UK registered company is your primary business entity — include Companies House number in all outreach	Yes

How to Get Your EIN Number

An EIN — Employer Identification Number — is the US equivalent of a company registration number. Most US wholesale suppliers require it before opening a trade account and Amazon USA requires it for tax reporting purposes. The good news is that UK companies can apply for an EIN for free directly through the IRS — the US tax authority — without needing to form a US company.

How to Find USA Wholesale Supplier Contact Details

Finding US wholesale supplier contacts follows the same fundamental process as finding UK contacts — with a few important differences in where the information is typically located and how US brands structure their trade programmes:

Source	How to Use It for US Brands
Brandhunterz Brands Directory	Filter by USA marketplace — verified trade contacts for US brands already confirmed
Brand website — Wholesale or Become a Dealer page	US brands often use “dealer” or “reseller” language rather than “stockist” — adjust your search terms
Google — [Brand] wholesale account USA	Surfaces US brand trade pages — add “Amazon seller” to filter for brands open to online resellers
SmartScout brand database	SmartScout covers Amazon USA data — filter US brands by revenue seller count and Amazon presence
LinkedIn	Search for Sales Representative National Account Manager or Wholesale Manager at US brands
US Trade Shows — ASD Las Vegas or Cosmoprof NA	The fastest way to open multiple US accounts — meet brands in person at major US trade events

How to Write Your Outreach Email to USA Suppliers

The outreach email to a US supplier follows the same structure as a UK supplier application — but you must address the international seller question proactively and confidently. US brands receive very few applications from international sellers and their first instinct is often to assume it is too complicated. Your job is to remove every logistical concern before they can raise it.

Why This Email Works for US Suppliers

Email Element	Why It Removes the Supplier’s Concern
EIN included alongside UK number	Proves you are properly structured for US trading — removes tax concern immediately
US prep centre address provided	Supplier ships to a standard US address — no international logistics complexity for them
USD payment confirmed	Removes any currency concern — supplier receives payment in their own currency
Amazon USA FBA stated specifically	Clear sales channel — supplier knows exactly where their products will appear

Understanding US Wholesale Supplier Differences

US wholesale suppliers operate slightly differently from their UK counterparts in several important ways. Understanding these differences helps you navigate the application process more effectively and avoid common misunderstandings that UK sellers encounter when approaching American brands for the first time:

US Supplier Characteristic	What to Expect and How to Handle It
Reseller Certificate requirement	Many US suppliers require a state reseller certificate for tax exemption — obtain one for the state where your prep centre is located
MAP pricing policies are strict	US brands enforce Minimum Advertised Price more aggressively than UK brands — never list below MAP
Higher minimum order quantities	US brands often have higher MOQs than UK equivalents — factor this into your starting capital
Authorised reseller agreements	Some US brands require a signed authorised reseller agreement before shipping — read carefully and sign professionally
Slower response times	US brands may take longer to respond due to time zone differences — factor 5 to 10 business days before following up
Credit card payment often preferred	Many US suppliers prefer USD credit card payment for first orders — use a business card with no foreign transaction fees

The US Prep Centre — Your Most Important Logistical Decision

A US prep centre is a third-party warehouse service based in the USA that acts as your receiving address for all supplier deliveries. When your wholesale order arrives at the prep centre the team inspects the stock labels each unit with FNSKU barcodes packs it according to Amazon FBA requirements and ships it directly to the Amazon fulfilment centre assigned in your Seller Central shipment plan.

What to Look For in a US Prep Centre	Why It Matters
Amazon FBA experience	Must understand FBA labelling packaging and shipment requirements precisely
Transparent per-unit pricing	Clear fee structure per unit received labelled and shipped — factor into your margin calculation
Fast turnaround time	Stock sitting in prep centre is stock not generating revenue — turnaround under 5 days is standard
Multiple state options	Choose a state with no sales tax where possible — reduces complexity of your reseller certificate
Inspection and damage reporting	Must check and photograph all incoming stock before processing — essential for supplier dispute resolution

Researching USA Products Before Approaching Suppliers

Product research for Amazon USA follows the same process as Amazon UK — but using US marketplace data. Always switch your Keepa settings to Amazon.com before researching any US product and use SmartScout filtered to the US marketplace to identify brands with strong revenue low seller counts and no Amazon presence on their listings.

Calculate your full landed margin — including prep centre fees and any import or shipping costs — using AMZScout before approaching any supplier. Your margin target for US products should still be a minimum of 30 percent ROI — accounting for the additional prep centre cost which typically adds $0.50 to $1.50 per unit depending on the service required.
