March 2026 is destined to be a nerve-wracking month for Amazon sellers.

From mid-month to the end of the month, three major new policies took effect within just 20 days: on March 12, the new reserve fund policy extended the payment collection period; on March 25, the big spring promotion rules were overhauled and redefined the traffic allocation; on March 31, the FBA labeling policy completely changed the shipping process. This is not a sporadic adjustment, but a precise "triple strike".

Some people only focus on how to increase sales volume during the spring promotion, only to find that the labeling rules have changed when shipping at the end of the month; some people are only rushing to collect payments before the new fund rules take effect, but miss the traffic window of the big promotion. Understanding the internal logic of these three policies is the key to landing smoothly in this "policy superimposed strong cycle".

The first strike: On March 12, the new reserve fund policy extended the payment collection period

Starting from March 12, Amazon will implement a new reserve fund policy, requiring sellers' payment to wait for another 7 days after the logistics shows successful delivery before it can be transferred to the account.

This rule, known as "DD+7", means that the payment collection period is generally extended. The impact on sellers using the self-fulfilled (FBM) model is particularly significant - since its delivery time is relatively long, plus the 7-day reserve period, the overall payment collection period may be extended to 20 to 30 days.

Cash flow pressure is not unique to small sellers. Recent examples of some large home furnishing companies suspending work and production due to financial problems highlight the importance of maintaining operational flexibility in an uncertain environment.

Response strategy:

If you are an FBM seller, it is recommended to immediately calculate whether the existing capital reserve can support a 30-day turnover period. For those with tight capital chains, consider slowing down the stock preparation rhythm appropriately, or negotiating with suppliers to extend the payment period. At the same time, use Amazon's "Instant Transfer" function (if activated) to withdraw part of the funds in advance in case of emergency.

The second strike: On March 25, the spring promotion rules were overhauled

From March 25 to 31, Amazon's US site spring promotion officially started, but this year's promotion rules have undergone major adjustments.

The good news is: Lightning Deals (LD) and Best Deals (BD) are exempt from seller reporting fees, which is expected to significantly reduce seller costs and encourage more sellers to participate.

The bad news is: During the event, Prime member exclusive discounts will no longer display the exclusive Prime logo, and the visual recognition is greatly reduced, which may directly affect the click-through rate and conversion rate. It should be emphasized that this adjustment only applies to the US site, and the European site will still retain the logo.

Response strategy:

Officials suggest that sellers should not rely solely on a certain promotional tool, but should build a combined traffic matrix:

· Use LD/BD as the foundation: Use LD/BD with no reporting fees to obtain basic traffic and conversion

· Use Coupons for visual enhancement: Set coupons on product pages and use green labels to enhance visual appeal

· Use SBV videos to intercept traffic: Cooperate with brand promotion video ads to attract high-intention users on the search results page

· Differentiated discounts: Set differentiated discounts according to variants in different price ranges to improve overall conversion rate

The third strike: On March 31, the FBA labeling policy was completely revolutionized

On March 31, Amazon will officially implement the new FBA product labeling policy and terminate the long-standing "shared inventory" mechanism.

Core changes:

· Good for brand sellers: Sellers who have completed brand registration and have the "Brand Representative" sales role can directly use the manufacturer's barcode (such as UPC) for warehousing without additional labeling, and the inventory remains independent

· Dealers must label: All dealers (including authorized dealers), regardless of whether the product has a manufacturer's barcode, must label each product with an Amazon barcode (X00 label) before shipping and warehousing

Consequences of non-compliance: After March 31, inventory sent by dealers without an Amazon barcode will be considered defective products, which may affect the timeliness of warehousing and listing, and does not meet the compensation requirements.

Response strategy:

· Brand sellers: Log in to Amazon brand registration to confirm that you have the "Brand Representative" role, select "Manufacturer Barcode" when creating a shipment, and gradually transition to label-free warehousing

· Dealers: Immediately download the affected ASIN list, create new SKUs for each affected ASIN and use Amazon barcodes to ensure that all shipments created after March 31 are labeled with X00 labels

· Warm reminder: No action is required for unlabeled inventory that is already in transit or stored in the operation center and can continue to be sold

Written at the end

Looking at these three new policies together, Amazon's logic is actually very clear:

· Fund rules: Use a longer payment collection period to ensure the safety of platform funds and force sellers to establish healthy cash flow

· Spring promotion adjustment: Use traffic allocation rules to guide sellers to build a diversified promotional matrix and reduce dependence on a single tool

· Labeling new policy: Use differentiated treatment of inventory independence to encourage sellers to take the branded route

For sellers, March is a "stress test month", but it is not the "finish line". It is recommended that you circle these time nodes on your calendar and prepare in advance:

· Before March 12: Calculate cash flow to ensure the safety of the capital chain

· Before March 25: Plan the spring promotion promotional combination well, LD/BD+Coupon+SBV video

· Before March 31: Complete the switch of labeling method to avoid shipment rejection

Those who understand the rules layout in advance, and those who don't understand are passively beaten. In 2026, those who survive are the wise, and those who live well are those who understand the rules in advance.
