Tantech Secures 'TANHOME' Trademark in Bid for U.S. Green Building Market

LISHUI, China – January 30, 2026 – Tantech Holdings Ltd. (Nasdaq: TANH), a company historically known for its bamboo charcoal products, has signaled a major strategic pivot by securing a critical intellectual property foothold for its expansion into the North American green building materials sector. The company announced today that its U.S. subsidiary, Tanhome Group Inc., received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for the “TANHOME” trademark. This move is a cornerstone of its ambitious 'Green Home Ecosystem' strategy, aimed at capturing a slice of the rapidly growing market for sustainable construction products.

A Blueprint for a 'Green Home Ecosystem'

The trademark allowance is more than a legal formality; it represents the formal branding foundation for Tantech’s multi-faceted entry into the U.S. market. The 'TANHOME' brand is slated to cover a comprehensive range of products and services designed to create a one-stop-shop for eco-conscious builders and homeowners. Upon completion of the registration process, the trademark will grant Tantech exclusive commercial rights in several key categories:

• Flooring Products (Class 019): A core component of any home, this category includes ceramic tiles, hardwood, and laminate flooring, all intended to be marketed under the company's eco-friendly banner.
• Cabinets and Storage (Class 020): The trademark will also protect the 'TANHOME' brand for cabinets and various cabinet storage solutions, another essential element of home construction and renovation.
• Business and Retail Services (Class 035): Crucially, the protection extends beyond physical goods to the business model itself. This includes business management assistance for franchising, as well as wholesale and retail store services featuring the company's branded cabinets, furniture, and flooring products.

This three-pronged approach indicates a strategy that encompasses manufacturing, distribution, and a branded retail experience. Zheyuan Liu, CEO of Tantech, highlighted the significance of this milestone in a public statement. "Receiving the Notice of Allowance from the USPTO is an important step forward for our 'Tanhome' brand globalization strategy," he commented. "As we implement our growth strategies in North America, possessing intellectual property assets under strict legal protection is paramount. This not only safeguards our brand credibility as a one-stop provider of eco-friendly building materials solutions, but also lays a solid compliance foundation for our future operational expansion in the U.S. market."

Targeting a Burgeoning Multi-Billion Dollar Sector

Tantech's strategic move is aimed squarely at the lucrative and expanding North American green building materials market. Industry analysis reveals a sector ripe with opportunity, driven by heightened environmental awareness, supportive government initiatives, and increasing consumer demand for sustainable living. The global green building materials market was valued at over $422 billion in 2023 and is projected to grow at a compound annual growth rate (CAGR) of over 12%, potentially reaching nearly $1.2 trillion by 2032.

North America currently represents the largest piece of this pie, accounting for over 32% of the global market in 2023. The U.S. market alone is forecasted to swell to an estimated $289.5 billion by 2032. This growth is fueled by a fundamental shift in the construction industry, where materials are increasingly chosen for their ability to reduce the environmental impact associated with their entire lifecycle, from extraction and fabrication to transportation and eventual disposal. By positioning 'TANHOME' as an eco-friendly brand, Tantech is attempting to align itself directly with these powerful market trends.

An Evolution from Bamboo Roots to Building Blocks

This ambitious foray into the U.S. building materials industry marks a significant evolution for Tantech. Founded in 2002, the company built its reputation as a high-tech enterprise specializing in the research, development, and production of bamboo charcoal-based products. With a range of home goods and an established sales network, Tantech became a recognized name in its niche, earning ISO 90000 and ISO 14000 certifications for its quality and environmental management systems.

However, the company began a strategic diversification in recent years. In 2024, Tantech officially entered the home building materials industry, a move preceded by the establishment of its U.S. subsidiary, Tanhome Group Inc., in 2022. The company further solidified its North American commitment in late 2024 by forming two additional U.S. subsidiaries, Gohomeway Inc. and Gohomeway Group Inc., also tasked with expanding its footprint in the green building sector through wholesale distribution and franchising. This pattern of strategic investments demonstrates a deliberate, multi-year plan to transform from a specialized product manufacturer into a global provider of diversified green home solutions.

A High-Stakes Play Amidst Market Volatility

While the strategic vision is clear, Tantech's expansion is a high-stakes bet for a company that has faced significant market headwinds. The company's stock (TANH) has experienced extreme volatility, with its share price declining by more than 80% over the past year. Tantech has also previously navigated compliance issues with Nasdaq regarding its minimum bid price, undertaking share consolidations to regain compliance. This financial backdrop paints a picture of a small-cap company making a bold, potentially transformative leap.

Despite the stock's performance, the company's underlying financials show a more complex story. Tantech reported revenues of nearly $42 million and profits of almost $5 million over the last twelve months, with earnings having grown at a strong average annual rate. This suggests an operational core that the company hopes to leverage for its new venture. The success of the 'TANHOME' brand will be a critical test of this strategy. The Notice of Allowance is a key approval, but it is not the final step. To complete the trademark registration, Tantech must file a 'Statement of Use' with the USPTO within the next six months, providing evidence that the brand is actively being used in U.S. commerce. This next milestone will be a crucial indicator of whether Tantech's blueprint for a 'Green Home Ecosystem' can be successfully built into a market reality.
