Shein launches new products every day — literally. More than 1,000 new designs are added to the catalog each week, and a portion of these arrive at the Pruebas Center as products available for free evaluation.
The new collection products are exactly the ones that need to be evaluated: there are no reviews yet, and the first reviews determine whether the product will sell well or be discontinued.
How to launch new collections
Unlike traditional brands that launch seasonal collections (spring/summer, autumn/winter), Shein operates with a continuous model:
- Daily: 200-500 new products are added to the catalog
- Weekly: complete categories are renewed
- Monthly: themed mini-collections appear (collaborations, special editions)
- Seasonally: major catalog changes focusing on the following season
This constant flow means that there are always new products arriving at the testing program. You don't need to wait for a “collection launch” like conventional brands.
New products in the tester program
The newly published products — with 0-5 reviews — are the ones that Shein most prioritizes for the testing program. The logic is direct: a product without reviews does not generate confidence among buyers. The first 3-5 reviews with photos are critical for initial sales.
This creates a clear opportunity:
| Product | Existing Reviews | Shein priority for tester | Your probability |
|---|---|---|---|
| Recently published | 0 | Maximum | Very high |
| Published 1 week ago | 1-5 | High | High |
| Published 2 weeks ago | 5-20 | Average | Average |
| 1+ month published | 20-100+ | Baja | Baja |
Applying for products with 0 reviews is the most effective strategy for maximizing approvals.
Strategy: apply early
The timing within the week matters:
- Monday and Thursday morning: the days with the highest number of new products published
- Primeras 24 horas: the window with the lowest competence per product
- Weekend: less activity from other testers, which can benefit requests sent later
Reviewing the program every month and every morning — before the majority of users do it — is the most impactful action you can take.
Difference between “new season” and “new collection”
On the Shein app, these terms appear in different contexts:
New season: wide stationary exchange rate. When spring arrives, the entire section of spring clothes is renewed. Affects thousands of products simultaneously.
New collection: it could be a thematic mini-collection (collaboration with influencer, limited edition, capsule collection). They are more specific and appear irregularly.
New products (in the program): any newly published product, regardless of whether it belongs to a specific “collection”. These are the most relevant for the tester.
New most recurring items in the program
The types of products that appear most frequently as novelties:
- T-shirts with new designs: the category with the most rotation of new releases
- Seasonal dresses: each seasonal transition brings decades of new designs
- Trendy accessories: jewelry and glasses that replicate social media trends
- Sportswear: expansion category with frequent launches
- Home products: seasonal decoration and organizers with updated designs
How to track releases
To avoid losing recently published products:
1. Activate notifications from the app: Shein can notify about news on program 2. Review Monday and Thursday: main update days 3. Save categories of interest: identifies which categories are renewed most frequently 4. Follow Shein on social media: collection launches are announced beforehand on Instagram and TikTok
