Key dates for managing your articles
This article provides an overview of the key timelines for managing your assortment on Zalando. Use this guide to plan ahead for season switches, retagging submissions and assortment quality measures.
Upcoming season switch
The next season switch is scheduled for July/August 2026. This switch will establish Autumn/Winter 2026 (AW26) as the main season, and move articles from the following seasons into sale:
Spring/Summer 2025 (SS25)
Autumn/Winter 2025 (AW25)
Spring/Summer 2026 (SS26)
To remain online, these past season articles require a minimum discount of 10% across all markets, and will stay online for a maximum of one year from the switch date. Exact dates and market-specific rates will be announced closer to the time.
Season switch dates and discount rates per market
Here are the season switch dates per market and the minimum discount rate required for old season articles.
Take full advantage of the season switch by adapting your prices to the minimum discount before the official switch date listed on the above table per market.
What is the Assortment relevance review?
The Assortment relevance process evaluates your articles using signals from observed customer behaviour. When signals show an article isn't relevant enough compared to similar ones in the same market, we take action.
If performance is low in a specific market, low visibility might be applied locally.
If performance is very low, we'll deactivate the article globally across all markets to ensure customers' shopping experience.
Please find more information about our assortment relevance process below:
What is retagging?
Retagging is the process of updating an article’s designated season (e.g. a SS25 article can be retagged to SS26). This lets you market and sell your articles for an additional season at full price.

New: More retagging flexibility
Important
These changes are effective from 1 October.
We've removed two previous limitations from the article classification process to give you greater flexibility when managing seasonal articles:
No conversion to Year-Round Basics: You're no longer required to convert older seasonal articles to Year-Round Basic (YRB) articles.
Unlimited retagging: We've removed the rule limiting article retagging to twice. You can now retag seasonal carryover articles from season to season without limits, provided they meet our quality requirements.
Automated category blocks
To maintain a fresh store assortment, automated retagging blocks apply to specific sports categories with high seasonal sensitivity:
Running Shoes (CG3): Articles older than two initial seasons are automatically blocked from retagging.
Football Jerseys (CG5): Season-to-season transitions (e.g. Spring/Summer to Autumn/Winter) are automatically blocked.
Faster retagging results
By automating core steps in our retagging review process, we've cut processing timelines significantly. You'll now receive your retagging results 5 days earlier, giving you an extended buffer to review decisions before the next submission period opens.
The updated timeline applies automatically with no further action on your side required.

What is the Basics review?
Basics (or Year-Round Basic (YRB)) articles undergo a monthly review process where they must meet specific criteria. This review ensures that these articles have consistent stock replenishment to meet ongoing customer needs. If an article doesn't meet the requirements, it is converted into a seasonal article.
The Basics review requirements
To remain classified as a basic article, an article must meet all of the following:
A Size Availability Rate (SAR) of over 85%.
gross merchandise volume (GMV) of over €1,000.
Fulfil the current image requirements.
The review checks if the article meets either the SAR or GMV threshold, as well as our image requirements. If these requirements are not met, the article will be converted to a seasonal article.
