Product Detail Page Rules

Customers will first learn about your offers on a product detail page. The policies below ensure each product detail page covers a single unique item. This helps give customers a clear and consistent buying experience. In general::

  • Comply with any relevant style guides and refrain from using HTML, JavaScript, or other code.
  • Exclude inappropriate content such as obscene or offensive materials, links or contact information, plot spoilers, reviews or requests for reviews, and advertising.
  • Accurately categorize and describe your products. Products cannot be classified incorrectly. Make sure to specify the leaf node for the specified browse node ID during Add Products via Upload. However, if you are unable to provide the corresponding leaf node, you may specify a branch node one level above the leaf node. If it is determined that an item is categorized inappropriately or inaccurately (including unspecified nodes), measures may be taken to temporarily suspend the account.
  • Refrain from creating duplicate pages for a product that already has a detail page.
  • Create new detail pages for new products or versions.
  • Only create valid “variations” that relate to the primary product. For more details, please see the Variations Policy.
  • Understand and comply with Amazon's policies on product safety and compliance. For more information visit the Product Safety and Compliance page.
  • If you wish to sell a product under a different trademark (i.e., brand or manufacturer name) to that of an existing ASIN (or where an existing ASIN has been created without a brand or manufacturer), do not change the existing ASIN. Instead, create a new ASIN for that trademarked product.
  • Detail page information must be added in the local language of the specific marketplace (i.e., Japanese for, German for, Portuguese for, etc.). Foreign Books are the only category where listings in foreign languages are allowed; in this case, the language of the detail pages' content shall be either the local language of the specific marketplace or the same language of the book being sold.

Policies for writing listings

  • Using page-creation tools for any purpose other than creating product details pages is prohibited.
  • Comply with the relevant style guide for the product you're listing. .
  • Don’t use HTML, JavaScript, or other types of code in your product detail pages.

    • Information that is grossly harmful, harassing, blasphemous, defamatory, pedophilic, libelous, invasive of another's privacy, hateful or racially/ethnically objectionable, disparaging, relating to or encouraging money laundering or gambling, pornographic, obscene or offensive content or otherwise unlawful in any manner whatever.
    • Details of availability, price, or condition.When listing a product for sale, sellers must follow the Amazon offer listing process. Within the offer listing process, sellers are given an opportunity to note their item's condition, quantity, price, and other details that are relevant to a specific listing.
    • External contact information such as but not limited to: Phone numbers, physical mail addresses, e-mail addresses, social media handles, or website URLs.
    • Links or references to alternative ordering information (such as links to other websites for placing orders), or alternative shipping offers (such as free shipping)
    • Detail pages may not feature or contain prohibited content or Restricted Products.
    • Spoilers on Books, Music, and Video or DVD (BMVD) listings. This includes giving away plot details crucial to the suspense or surprise ending of a story.
    • Reviews, quotes, or testimonials.
    • Requests for positive customer reviews.
    • Adverts, promotional material, or watermarks on images, photos, or videos.
    • Time-sensitive information, such as dates of tours, seminars, or lectures.
    • Display of trademarks on generic products
    • Information containing software viruses or any other computer code, files or programs designed to interrupt, destroy or limit the functionality of any computer resource.
    • Information violating any law of the marketplace country for the time any such law is being in force.
    • Generic products may not be listed under ASINs of trademarked products, even if the products are similar or identical.
  • Product title length must be within 50 double-byte characters including spaces in all categories. Some of the categories may have a different maximum title length than 50 double-byte characters. To know the accurate maximum title length for your respective category, please refer to your category specific style guide.
  • Comply with Amazon listing standards for any product sold on Amazon. Failure to do so creates a negative customer experience and may result in your selling privileges being temporarily or permanently removed. This includes but is not limited to the following:
    • All products must be accurately categorized. To learn more about classifying your products correctly, see our help pages on Browse Tree Guide, and ASIN Creation Policy.
    • Product titles, product descriptions, and bullets must be clearly written and help customers understand the product.
    • Product images must meet Amazon image standards, as well as any category-specific image guidelines. To learn more, see the Product image requirements.

Policies for adding detail pages

  • You must not use Add a Product, inventory files, and Amazon Marketplace Web Services (Amazon MWS) listing APIs for any purpose other than listing products on Amazon.
  • You must not use false product identification information in product detail pages. This includes UPC codes and publication dates.
  • You must not create a product detail page for a product already in Amazon's catalog, including products listed on other Amazon marketplace websites (i.e.,,, etc.)
  • You must not use product detail pages to cross-merchandise or cross-promote a product.
  • For Books, Music, Videos, and DVDs (BMVD), you must not use a single product detail page to advertise more than one product. BMVD-only product bundles must be defined by the publisher or manufacturer and have a single ISBN, UPC, or EAN that is different from the product identifier of any single item in the bundle.
  • You cannot add details with infringing upon the IP rights of other parties or individuals. For more details, check the Intellectual Property Rights for Sellers page.

Policies for editing detail pages

  • You must not use an existing listing for a new version of a product. Changes to a product’s packaging color, design, or material do not require creating a new ASIN. Only when the product being sold is either materially different or changed in brand value is it necessary to create a new ASIN. This includes changes in color, size, material, features, and product name. For example, a manufacturer updates its streaming media player by adding a new remote control with four buttons instead of two. This product is materially different from the older version and it must be listed as a new ASIN.
  • You may only update detail pages to better or more accurately describe the product as originally listed. You may not change/add the ASIN title, brand, or manufacturer name in the respective data fields (even if one does not exist, i.e. where the ASIN was created without a brand or manufacturer as a ‘no-name’ or generic product) unless the updates include additional details, clarifications, grammatical fixes, or removal of content that violates Amazon policy.
  • If you choose to re-brand a product you must create a new ASIN rather than update an existing ASIN. This is true even if the product is unbranded and does not change materially after the brand change. This includes adding a brand to a previously unbranded product.
  • If you believe that the brand or manufacturer name on an existing ASIN is incorrect, please contact Seller Support and provide all available evidence to support your position. This includes if you are unable to list a product with the correct UPC because that UPC is already in use for another ASIN. Do not make changes to the original ASIN. Instead contact Seller Support with proof of UPC ownership and request that they cleave a new ASIN for the same UPC.
