The U.S. trademark for Caiqinlen was filed on 14 January 2021 by Shenzhen Yibai Network Technology Co., Ltd. and subsequently registered on 10 August 2021.1

The primary evidence establishing Caiqinlen’s corporate ownership is its intellectual property registration. Trademark databases record CAIQINLEN (serial number 90467364) as belonging to Shenzhen Yibai Network Technology Co., Ltd. of China, with a filing date of 14 January 2021 and a registration date of 10 August 2021.2 Independent trademark records further list CAIQINLEN among a portfolio of brands associated with Shenzhen Yibai Network Technology.3

This association suggests that Caiqinlen operates as part of a multi-brand e-commerce strategy managed by a single organisation, rather than as an independent traditional manufacturer. However, available public sources do not confirm that Shenzhen Yibai physically manufactures every product sold under the Caiqinlen name. The extensive variety of product categories makes a single-factory manufacturing model improbable.

Caiqinlen lacks the documented corporate history typical of established consumer electronics or appliance manufacturers. The brand’s publicly verifiable timeline begins with its intellectual property filings:

• 14 January 2021: The CAIQINLEN trademark was filed by Shenzhen Yibai Network Technology Co., Ltd. for goods in International Class 7, covering machinery and machine-related products.4
• 10 August 2021: The trademark was officially registered in the United States.2

Following registration, products bearing the Caiqinlen name began appearing across various international e-commerce platforms. While 2021 marks the earliest clearly documented point in the brand’s visible history, this does not necessarily indicate the precise moment of the brand’s creation or first commercial use.

A defining characteristic of Caiqinlen is the breadth of its product catalogue, which extends far beyond its original trademark classification.

Machinery and Tools

The brand’s U.S. trademark registration specifically covers machinery and tools, including:

• Electric mixers and egg beaters
• Electric hammers and power tools
• Vacuum cleaners
• Woodworking and sanding machines
• Laser engraving machines
• Mowing and reaping machinery
• Sausage-making machines and milking-machine components
• Machine components

Consumer and Household Goods

Marketplace listings indicate that the brand is not restricted to industrial equipment. Documented products include:

• Home & Kitchen: Tortilla presses, mini refrigerators, dehumidifiers, and kitchen tools. For instance, retailers have listed Caiqinlen aluminium tortilla presses intended for flatbreads and pastries.4
• Electronics & Cooling: Thermoelectric Peltier cooling plates, compact refrigerators, and electronic accessories. Listings describe Caiqinlen Peltier cooling plates as 240 W thermoelectric products with aluminium construction and 12 V power input.7
• Automotive & Mechanical: Small-engine components, pocket-bike parts, and workshop equipment. Aggregator sites have listed Caiqinlen-branded clutches for 43cc, 47cc, and 49cc engines.21
• Pet Products: Dog boots, animal accessories, and milking equipment. European marketplaces have stocked Caiqinlen dog boots featuring Velcro closures, plush lining, and non-slip rubber soles.51118
• Gardening: Manual garden tools, digging implements, and grafting tools.13
• Toys & Hobbies: Miniature cameras, RC equipment, craft supplies, and dart accessories. Listings have included Caiqinlen RC servos and miniature dollhouse cameras.6151619

Other miscellaneous items found in marketplace listings include metal detectors,8 scooter accessories,17 motorcycle frame sliders,21 spark plug testers,22 and DIY wood crafts.16

Caiqinlen’s market positioning differs significantly from that of a specialist manufacturer. Evidence points to a private-label e-commerce model characterised by four key elements:

1. Broad Product Coverage: The brand encompasses machinery, home goods, electronics, pet supplies, and niche hobbyist items rather than focusing on a single vertical.
2. Marketplace-Centric Distribution: Products are primarily distributed through Amazon-associated marketplaces and regional e-commerce platforms in Europe and Asia.620
3. Functional Value Proposition: The catalogue consists mainly of practical utility items, replacement parts, and specialised equipment rather than luxury or lifestyle goods.
4. Long-Tail Inventory: The brand includes obscure or highly specific products, such as niche agricultural equipment or specialised mechanical components, which are characteristic of cross-border e-commerce strategies targeting specific search queries.

While some product pages identify Caiqinlen as the manufacturer, this designation likely reflects the brand owner rather than the physical factory. Given the diversity of the catalogue, it is more accurate to describe Caiqinlen as a private-label brand under which varied products are marketed internationally, potentially sourced from multiple third-party manufacturers.

Product quality and customer experiences vary significantly due to the heterogeneous nature of the catalogue. Manufacturing standards for a tortilla press differ fundamentally from those for electronic cooling modules or textile pet accessories. Marketplace reviews reflect this variance; for example, listings for portable dehumidifiers have shown mixed feedback regarding performance and durability.8 Consequently, assessment of Caiqinlen products requires evaluation of individual specifications, safety certifications, and seller reputations rather than reliance on the brand name alone.

Shenzhen Yibai Network Technology Co., Ltd. maintains a portfolio of numerous marketplace brands. Trademark records associate CAIQINLEN with other labels such as GUPBES, GOSHYDA, YOIDESU, PISSENTE, WAKECTS, GERMERSE, YCTZE, and COCOSITY.3 This pattern supports the conclusion that Caiqinlen is one asset within a broader multi-brand e-commerce operation designed to capture demand across different product categories on international platforms.

Caiqinlen does not operate a network of branded physical stores. Distribution is conducted exclusively through online channels, including:

• Amazon Marketplace
• European e-commerce platforms (e.g., Galaxus, bol.com, Cdiscount)451520
• Price comparison websites7
• Specialist online retailers822
• Regional marketplaces in Asia and Africa1718

Availability, pricing, and product selection vary substantially between countries and platforms. There is no centralised direct-to-consumer website for the brand.

Caiqinlen is best classified as a Chinese-associated brand with an international focus. The trademark owner is based in Shenzhen, China,1 but there is little public evidence of significant presence in China’s domestic retail market. The brand’s visibility is almost entirely tied to cross-border e-commerce exports.

Caiqinlen should not be confused with Jiangsu Caiqin Technology Co., Ltd., a separate Chinese entity established in 2004 that specialises in electronic ceramics, microwave dielectric ceramics, filters, and antennas. There is no evidence linking Jiangsu Caiqin Technology to the Caiqinlen trademark or its associated product catalogue. The similarity in naming appears to be coincidental.

Caiqinlen is a verified registered trademark associated with Shenzhen Yibai Network Technology Co., Ltd., with U.S. registration dating to August 2021.29 It functions as a private-label vehicle for a wide assortment of practical goods distributed internationally via online marketplaces.1012 While firmly linked to machinery and tools through its trademark classification, its actual commercial application spans household, automotive, pet, and hobbyist categories.14 Public information regarding the brand’s internal operations, financial performance, and specific manufacturing facilities remains limited.
