A product with a healthy margin at home can be wiped out the moment it enters Amazon’s US marketplace. The surface story is simple because Amazon now gives South African sellers a direct route into that market through Seller Central, with account setup, listing tools, fulfillment choices, and Brand Registry support. The harder story is the one most brands only meet after the first shipment leaves Durban or Cape Town: unit economics can turn ugly very fast.
A skincare brand, a food-safe kitchenware label, or an outdoor-accessory maker can sell a $40 item and still lose money once freight, customs, Amazon fees, storage, returns, ads, and currency conversion are all pulled into the same spreadsheet. Access is open, but profit is not guaranteed.
The market opens faster than the maths
Amazon’s local Seller Central setup removes some old friction. A business can create a US selling account, list products, manage inventory settings, and carry Brand Registry protections across stores without building a separate web stack from scratch. For a small manufacturer, this lowers the administrative barrier to selling into a market far larger than most local brands can reach on home soil.
Access and readiness are different things.
A seller still has to get the product across the ocean, clear it through US import rules, price it inside a marketplace where the platform takes a cut at almost every stage, and then keep enough cash in reserve to survive returns, advertising spend, and exchange-rate movement. A business that looks efficient in rand terms can become brittle once everything is priced in dollars.
That is the trap. A founder sees a $40 shelf price and assumes the margin can travel. The shipping invoice, the Amazon statement, and the ad dashboard usually disagree.
A $40 product can break on the way to checkout
Take a locally made skincare product that sells well at home. Imagine a manufacturing cost of R200 per unit, about $10.81 at R18.50 to the dollar. At first glance, a $40 US price looks generous. It is not.
Now add the cost stack:
- International freight from South Africa to the US, which can run from $5 to $15 per unit for smaller items if you are moving by air, or less per unit by sea if you are sending volume.
- Customs brokerage and import charges, which sit on top of the freight bill.
- US duties, depending on the tariff code, plus processing and port-related fees.
- Amazon referral fees, usually somewhere between 8% and 15% of the sale price, which on $40 is roughly $3.20 to $6.
- Fulfillment by Amazon charges for pick, pack, and dispatch, plus storage fees for inventory that does not move quickly.
- Returns and damaged stock, which hit harder in categories where customers are fussy or product fit is subjective.
- Advertising, because most new listings do not sell themselves on day one.
- Currency conversion fees when Amazon pays out in dollars and converts the money back to rand.
A clean local margin can disappear after only a few of those line items. A $40 sale is not $40 earned; it is a starting point for a long deduction chain.
For a new listing, advertising alone can eat a serious chunk of revenue. If the product needs paid search to get traction, an initial advertising cost of sale in the 20% to 40% range is not unusual. On a $40 item, that means $8 to $16 in ad spend per sale before the campaign has even settled.
A rough unit economics check
A basic model for one unit might look like this:
- Selling price: $40
- Product cost: about $10.81
- Freight and import handling: $6 to $12
- Amazon referral fee: $3.20 to $6
- FBA fulfillment and storage allocation: about $3.22 to $4.75 for a small standard-size item, plus storage
- Advertising: $8 to $16 at launch
- Returns and damage allowance: variable, but not zero
- Currency conversion fee: another 2% to 3% on the payout
That is already enough to push the unit into the red.
The product can still look healthy on a local spreadsheet. A seller may be used to a nice gross margin in rand terms, then discover that the same item behaves very differently once it is sold into a market where every link in the chain charges separately.
FBA and FBM are not the same game
Amazon gives sellers two broad ways to fulfill US orders, and the difference is not cosmetic.
Fulfilled by Merchant, or FBM, means the seller ships each order from South Africa after it is placed. That keeps stock control in-house and avoids Amazon storage costs, but it is usually a poor fit for competitiveness. Individual international parcels are slow, expensive, and awkward for the customer. For a $40 product, that model tends to punish conversion and invite bad reviews.
Fulfilled by Amazon, or FBA, changes the logic. The seller sends inventory in bulk to Amazon’s US fulfillment network, and Amazon handles storage, packing, shipping, customer service, and returns. The seller pays for that convenience through fulfillment fees, storage fees, and the upfront cost of holding stock in the US. The trade-off is faster delivery, Prime eligibility, and a better chance of showing up as a credible option in search.
For a small export brand, FBA is usually the only route that scales. It is also the route that forces the discipline of working capital. Inventory has to be paid for before it can be sold, freight has to be paid before it lands, and Amazon takes its cut after the sale. Cash flow gets tight quickly.
The checklist before you list anything
A seller who wants to test the US market needs more than a nice product photo and a price conversion. The product has to be ready for the market, not just visible in it.
Check demand first
- Look for real search demand in the category.
- Study competitor pricing, review volume, and saturation.
- Decide whether the product solves a problem Americans already pay to solve.
Check the legal basics
- Register the trademark in the US if brand protection and Brand Registry are important.
- Make sure the product name, design, and packaging do not clash with existing rights.
- Carry product liability insurance, often at levels between $1 million and $2 million.
Check labeling and compliance
- Skincare products need ingredient disclosure, net contents, warnings, and manufacturer information that comply with US rules.
- Food-safe kitchenware needs the right material and origin labeling.
- General consumer goods may fall under Consumer Product Safety Commission rules.
- Electronics and similar items may need specific certification before they can move properly.
Check fulfillment and cash
- Decide whether the product can survive FBM, or whether FBA is the only realistic option.
- Model the landed cost per unit in dollars, not rand.
- Include returns, storage, ads, and currency conversion in the model.
- Keep enough working capital to fund inventory cycles, not just the first shipment.
The point is not to ask whether the brand is good. The point is to ask whether the economics still work after the product leaves home soil.
The real opportunity is narrower than the headline suggests
Amazon has made exporting possible. For the right brand, it opens a much larger customer base and gives a local manufacturer access to a market that can absorb far more stock than the home market ever will.
Access is not the same as advantage. A South African seller can now reach US buyers through a familiar interface, transfer Brand Registry benefits, and plug into Amazon’s fulfillment machine. None of that removes export compliance, import charges, marketplace fees, or the cost of winning attention inside Amazon’s own search results.
The first question is not whether the product can be listed. It is whether a R40 or $40 item can survive the trip without the margin being eaten alive on the way there.
A business that can answer that honestly has a shot. A business that cannot is just sending expensive stock into a very efficient machine.
