Effective from: 10 September 2026
This policy sets the standards for new content and substantive updates published by Longchang Chemical on longchangextracts.com. Our focus is chemical identity, material specifications, industrial applications, research interpretation and procurement information.
Publication responsibility and bylines
Shandong Longchang Chemical Co., Ltd. is responsible for publication. The Longchang Chemical byline identifies company-published content. A company byline does not identify an individual medical reviewer. When an individual author or reviewer is named, their role and relevant background must be accurate. See Authors & Editorial Responsibility.
Sources and evidence
Material factual claims should be supported by sources appropriate to the claim. We prioritize official substance records, current regulatory and product information, original research, standards and identifiable technical documentation. Citations should point to the specific record or study used, rather than only to a general website.
Content should distinguish public reference values from supplier specifications and batch measurements. Catalog data must not be presented as a current batch guarantee. Clinical claims require evidence relevant to the population, formulation and use described; laboratory findings must be identified as laboratory findings.
Review and use of tools
Editorial review should check chemical names, identifiers, units, evidence, intended-use boundaries and the accuracy of commercial statements. Drafting, translation and research tools may assist preparation. Tool output must be checked before publication and must not be treated as an independent source of evidence. Reviewers must not invent studies, qualifications, test results or approvals.
Original contribution and attribution
Research summaries must identify their sources, respect copyright and distinguish the cited researchers’ work from Longchang’s own contribution. Useful editorial contributions may include comparisons, explanations of limitations, specification checks, procurement questions or clearly identified practical experience. Republishing or lightly rewriting another publisher’s work without meaningful contribution does not meet this standard.
Health and regulatory claims
Articles should avoid unsupported disease-treatment claims, guarantees of safety, and instructions for self-medication. Product descriptions must not imply that database registration or a research finding is regulatory approval. See the Technical & Medical Disclaimer.
Commercial interests and sponsored content
Longchang Chemical is a commercial supplier. Product links and inquiries may support our business, and that interest should be clear to readers. Paid editorial placements must display a visible Sponsored Content disclosure near the title or byline. Sponsored material remains subject to editorial review; payment does not establish scientific validity or guarantee search performance.
Commercial links in paid placements should be appropriately qualified for search engines. Sponsorship terms and accepted topics are described on the Industry Partnerships page.
Updates and corrections
Readers can request a correction by emailing info@longchangchemical.com. Include the page URL, the statement in question and supporting evidence where available. Reports should be reviewed against relevant sources. Substantive corrections should identify the update and its date; minor formatting changes need not be described as a new factual review.
A publication date records when an article appeared. A review date should be used only when a factual review actually occurred. Older articles may predate this policy and require further source verification; the presence of this policy does not certify that every historical statement has been clinically reviewed.
Translations
Some language versions use automated translation. Scientific names, units and regulatory terms should be checked against the source record. Please report a translation that changes a technical meaning. The policies linked from this page are published in English; contact us if you need clarification.
