As the spring promotion at the end of March has just ended, we haven't had time to catch our breath yet, and the new rules in April are already lining up to "harvest" your profits.

Killer One: Logistics Costs Add a "3.5%" Burden

The first and most direct impact on profits comes from logistics. Amazon has announced that due to the current international geopolitical conflicts, global supply chain costs have soared. Starting from April 17, 2026, Amazon will temporarily charge an additional "Fuel and Logistics Related Surcharge" of 3.5% for FBA delivery fees for US and Canada sites. A surcharge of 1.5% will also be levied on European sites.

How do we calculate this? Take a medium-sized standard product with a selling price of $30 and monthly sales of 1,000 units as an example. The average delivery fee per item was originally about $4. After the new rule takes effect, just this surcharge will cost you an additional $140 per month (1,000 units x $4 x 3.5%). And this is just the tip of the iceberg. As operating costs rise, you may have to raise prices to maintain profits, which will affect conversion rates and competitiveness in the Buy Box.

Response strategy: Amazon officially recommends that sellers log in to the backend immediately and use the "Revenue Calculator" and "Profit Analysis Dashboard" to view the specific cost structure. You need to recalculate the break-even point of your main ASIN, and consider whether you need to slightly raise prices before Prime Day or optimize your first-mile logistics channels.

Killer Two: Hidden Cost Increases in Advertising Settlement and Prime Day

The second hidden cost is hidden in your advertising settlement method and the upcoming promotion costs. Starting from April 15, Amazon will launch a new advertising settlement mode: advertising fees will be automatically deducted directly from your sales revenue, and third-party payment methods such as credit cards will only serve as backup deduction channels.

What's the implication behind this? In the past, sellers could use a credit card payment period of 30-60 days to flexibly manage cash flow. After the new rule, this buffer period disappears completely. With every order, the money is deducted to pay for advertising fees before it even warms up in your hands.

The third blow follows closely: Amazon has announced that the 2026 Prime Day promotion costs will be revised, canceling the previous fixed fee model and adjusting to "fixed prepaid + sales commission". On the US site, you need to pay a prepaid fee of $100, plus 1.5% of sales revenue. This means that once you have a surge in orders, your "toll" for the promotion on the platform will also soar.

Response strategy: Re-examine your cash flow reserves to avoid temporary shortage of funds due to advertising deductions. For Prime Day, calculate the marginal cost of promotion under high sales revenue, and combine the early bird discount of $50 reduction before April 30 to plan your pre-registration list in advance.

Killer Three: Price Manipulation "Bare Naked", Forcing You to Return to Reality

The last big move at the end of April falls on pricing strategy. In order to combat false discounts, Amazon has significantly tightened the display rules of "List Price". Starting from April 23, your arbitrarily filled inflated original prices will no longer be displayed. The system requires that your listed price must be a price that has been actually sold by other retailers or Amazon itself recently.

Subsequently, starting from May 18, large and frequent promotional prices will also be included in the product's "regular price" calculation system. For example, if a T-shirt of yours has been discounted at $15 for more than 45 days, when you want to raise it back to the original price of $30, the system will determine that your price fluctuation is abnormal, causing your Listing to no longer display the reference strike price, directly lowering the conversion rate. In the future, sellers can no longer arbitrarily use "inflated" prices to highlight discounts, and frequent price reductions can no longer easily beautify the historical prices of products.

Written at the end

Amazon in April is eliminating sellers with extensive operations through a "triple blow" of "hard logistics price increases, cash flow interception, and pricing transparency". For shrewd sellers, this is a time window to force themselves to finely calculate costs and return to product value. It is recommended that you take action immediately, check the above three new rules one by one, update your profit statement, and ensure that your cash flow and pricing strategy can land smoothly in April.
