Amazon is tightening its bundle policy while critical Q4 inventory and import deadlines arrive. At the same time, Amazon Ads is expanding into ChatGPT as AI reshapes how shoppers discover products.

In this September fifteenth episode of Selling on Giants, Mr. Will breaks down the marketplace changes that require immediate attention and what they mean for brands responsible for profitability, inventory, and execution.

What is changing with Amazon product bundles?

Beginning January eleventh, twenty twenty-seven, most bundles sold under a single ASIN must be packaged by the original manufacturer or brand. Seller-assembled bundles may require authorization, while virtual bundles and certain categories remain exempt.

Sellers need to audit existing bundle ASINs, secure authorization, calculate inventory sell-through, and identify listings that may become violations. A bundle is not a defensible product strategy simply because Amazon previously allowed it.

Which Q4 deadlines matter now?

Amazon Canada inventory must arrive at fulfillment centers by September sixteenth to guarantee Prime eligibility for Prime Big Deal Days. The Black Friday and Cyber Monday arrival deadline is October twenty-eighth.

Deal sourcing closes September twenty-ninth for Prime Big Deal Days and November thirteenth for Black Friday and Cyber Monday. Eligible price discounts require at least fifteen percent off the validated reference price.

U.S. importers also face a September eighteenth enforcement deadline. Customs and Border Protection may immediately void an Importer of Record number when Form 5106 contains inaccurate or incomplete information. Brands need to verify their physical address, contact information, tax identification details, and customs broker power of attorney.

How are Amazon Ads and ChatGPT working together?

Amazon Ads and OpenAI have launched a U.S. pilot that allows select advertisers to extend campaigns into conversational advertising experiences within ChatGPT.

The timing matters. Deloitte expects holiday eCommerce sales to grow between seven point five percent and eight point four percent, reaching as much as three hundred eighteen point nine billion dollars. Bain also reports that twenty-four percent of holiday shoppers plan to begin product discovery through generative AI platforms.

Amazon is now taking its advertising capabilities beyond Amazon-owned properties and into the conversations where shoppers research, compare, and make decisions.

Why are product images, reviews, and attributes becoming more valuable?

Target now supports AI-powered photo search and summarized review insights. Instacart and Shipt can build grocery carts from conversations, recipes, and uploaded photos.

Product discovery is expanding beyond traditional keyword searches. Images, ingredients, materials, pack quantities, use cases, reviews, pricing, and availability are becoming inputs that AI systems use to recommend products and assemble carts.

How are Amazon and Walmart tightening delivery standards?

Starting September thirtieth, Amazon requires a Business Hour Delivery Rate of at least ninety percent for seller-fulfilled Amazon Business orders. Sellers that remain below the requirement may lose access to Business customers beginning October thirtieth.

Walmart is also evaluating Walmart Plus badge eligibility over a fourteen-day performance window. Sellers need strong on-time delivery, low cancellations, sufficient order volume, and delivery promises of two calendar days or less.

Speed now affects marketplace eligibility, visibility, conversion, and profitability. Sellers need to evaluate fulfillment performance at the SKU and regional level before making faster promises that increase sales but eliminate margin.
