These terms explain the scope and permitted use of longchangextracts.com, operated by Shandong Longchang Chemical Co., Ltd. Questions may be sent to info@longchangchemical.com.
Website purpose
The website provides chemical and ingredient information, research commentary, product records and a channel for business inquiries. Information is intended to support technical evaluation and procurement discussions. It does not replace professional medical, safety, engineering or regulatory judgment.
Product records and quotations
A website listing is an invitation to discuss a requirement. It is not a binding offer, confirmation of current stock, batch-release certificate or guarantee that a material is suitable for a particular purpose. Specifications, test methods, quantities, packaging, delivery, payment and document availability must be confirmed in the applicable written quotation or agreement.
Where a separate contract is agreed, that contract governs the transaction. A public CAS number, research reference, certification reference or regulatory identifier does not by itself establish approval of a supplier, batch or intended use.
Technical and medical information
Evaluate information against current primary sources and the documents for the actual material or finished product. Research involving cells, animals, modeling or preliminary human studies must be interpreted within its stated limits. The website does not provide individual diagnosis, prescribing or treatment instructions. See the Technical & Medical Disclaimer.
Content ownership and permitted use
Unless otherwise identified, website text, design and original materials belong to Longchang Chemical or are used with permission. Third-party names, marks, images and research remain subject to their owners’ rights and applicable licenses. You may link to our pages and use material to the extent permitted by applicable law. Obtain permission before republishing substantial portions of our original content or using our branding in a way that suggests endorsement.
When submitting text, images or other materials, provide only content that you have the right to share. A publication or sponsorship arrangement may include additional written terms.
Acceptable use
Use the website lawfully. Do not submit spam or malicious files, impersonate others, attempt unauthorized access, misuse personal information, interfere with normal service, or misrepresent our products, identity or statements. Automated access must respect applicable restrictions and must not impair service.
External links and commercial content
External websites are operated by their respective owners. A reference link identifies a source or relevant resource; it does not imply endorsement of all content on that website. Paid editorial placements are identified as sponsored content. See our Editorial Policy and Sponsored Content & Industry Partnerships information.
Accuracy, availability and responsibility
Information can change, and errors may occur. We may correct, update or withdraw content and may interrupt access for maintenance or security reasons. Please report a suspected error with the page URL and supporting details. To the extent permitted by applicable law, general website information is provided without a promise of uninterrupted availability or suitability for a specific purpose. Nothing in these terms excludes rights or responsibilities that cannot lawfully be excluded.
Privacy and contact
Our Privacy Policy explains information handling. For content, permissions or website questions, use our Contact page. We may revise these terms; the date above records the latest revision.
