Amazon FBA sellers find wholesale suppliers through four reliable channels: trade shows, direct brand outreach, authorized distributors, and curated B2B marketplaces. Each channel produces different supplier profiles, margin structures, and approval timelines. The seller who builds a sustainable FBA business treats supplier sourcing as ongoing relationship work, not a one-time directory search.
Wholesale arbitrage replaces the unpredictable hunt of retail clearance bins with repeatable purchase orders from real brands. The tradeoff is paperwork: you need a registered business, a resale certificate, and the patience to get approved as an authorized reseller. The payoff is a sourcing model you can actually scale.

Where Wholesale Suppliers Actually Live
The biggest mistake new FBA sellers make is searching “wholesale suppliers” on Google and signing up for the first directory that appears. Real suppliers exist in places retail buyers have used for decades.
Trade shows. Industry trade shows are where brands meet retail buyers. ASD Market Week in Las Vegas, NY NOW in New York, Expo West for natural products, Outdoor Retailer for outdoor gear, and Toy Fair for toys are the major U.S. shows. Most issue free or low-cost buyer badges if you can show a resale certificate. You walk the floor, collect line sheets, and meet brand reps face to face. A single show can produce a year’s worth of supplier leads.
Brand websites. Many consumer brands list a “Wholesale Inquiries” or “Become a Retailer” link in the footer. Submit applications with your EIN, resale certificate, and a short pitch about your sales channels. Some brands restrict Amazon. Many do not, especially smaller brands trying to grow distribution.
Distributor networks. Distributors aggregate hundreds of brands under one account. Examples include UNFI for natural and grocery, KeHE for specialty food, Mizco for consumer electronics accessories, and McLane for general merchandise. Distributor minimums are higher than direct brand orders, but you get catalog breadth in exchange.
Curated B2B marketplaces. Platforms like Catalist, Faire, and Abound let you create one account and order from many brands. The catch with most of these platforms is that they were built for brick-and-mortar boutiques, and many brands block Amazon resellers in their terms. Read the reseller policies before ordering. Catalist’s marketplace, by contrast, is built for emerging brands actively seeking Amazon and ecommerce partners.

How to Get Approved as a Reseller
Finding a supplier is the easy part. Getting approved is where most new sellers stall. Wholesale suppliers want resellers who protect the brand and pay invoices on time, not anonymous Amazon accounts that race to the bottom on price.
Before you contact a single supplier, prepare a reseller packet:
- Business entity documents. LLC or corporation paperwork, EIN letter from the IRS.
- Resale certificate. Issued by your state’s department of revenue. Required for tax-exempt wholesale purchasing.
- Business address. Some suppliers require a commercial address, not a residential one. A coworking space or warehouse lease usually satisfies this.
- Sales channel summary. A short document listing your Amazon storefront, any other marketplaces, and your monthly volume.
- Bank or trade references. Useful for opening net-30 terms after your first few orders.
When you email a brand, lead with what you bring to the table. “I’m an authorized reseller on Amazon doing $X per month in your category. I’d like to discuss adding your line.” Avoid the phrase “Amazon arbitrage” entirely. Use “retail partner” or “authorized reseller.”
Expect rejections. Some brands have exclusive Amazon distribution deals. Some restrict third-party sellers entirely. Some require MAP (Minimum Advertised Price) agreements. Read every reseller agreement before signing, because MAP violations get accounts terminated.
For ungating restricted categories like grocery, beauty, or specific brands, you’ll need three invoices from a single supplier totaling at least ten units, dated within 180 days, with your business name and address matching your Seller Central account exactly. Wholesale suppliers produce invoices that pass ungating. Retail receipts from Target or Costco do not.
Vetting Suppliers and Avoiding Scams
The wholesale supplier search is full of fake middlemen, dropship aggregators charging 30% markups, and outright scams. A few rules separate real suppliers from time-wasters.
Real suppliers have real catalogs. They send line sheets with UPC codes, case packs, MSRP, wholesale cost, and MAP pricing. If a “supplier” sends you a spreadsheet of Amazon links with a 5% discount, walk away. That’s a reseller, not a supplier.
Real suppliers have minimum order quantities. A first order of $300 to $2,000 is normal for emerging brands. $5,000 to $25,000 is normal for established brands and distributors. “No minimum” is usually a sign of a dropship arbitrage scheme that won’t produce ungating invoices.
Real suppliers have phone numbers and warehouses. Call before you order. Ask about lead times, return policy, damaged-goods replacement, and whether they sell on Amazon themselves. If the brand sells on Amazon as a first-party vendor, you’ll be competing against the brand’s own listings on price.
Run the numbers before you order. Pull the ASIN into a Keepa chart. Check the number of FBA sellers on the listing, the Buy Box rotation, the 90-day average price, and the sales rank trend. A great wholesale cost on a product with 47 other FBA sellers is not a great deal. Aim for listings with three to eight competing sellers, stable pricing history, and a sales rank that signals real velocity.
Watch for tactical red flags. Wire transfers to overseas accounts on a first order, suppliers who “happen to be” in the middle of a closeout liquidation, brand reps using free email addresses, missing physical addresses, and reluctance to provide references. Any one of these is a reason to pause.
The sellers who build durable FBA businesses do the boring work: they go to trade shows, send 200 outreach emails, get told no by 180 brands, and turn the remaining 20 into accounts they reorder from for years. There’s no shortcut, but there is a clear playbook.
