Privacy Policy

Last updated: July 16, 2026

Business responsible for this website

Henan Dingxinda Import & Export Co., Ltd. operates the DXD Carbon website and handles international sales inquiries. Ningxia Yongruida Carbon Co., Ltd. may support manufacturing, technical and quality review when an inquiry requires factory input.

Information collected

We may collect your name, business email, phone or WhatsApp number, company, country, product interest, application, quantity, destination, message and uploaded specification files. Technical records may also include the source page, browser information, IP address, form-security data and campaign parameters such as UTM values or Google click identifiers.

How information is used

Information is used to review activated carbon requirements, identify a possible grade direction, prepare quotations, coordinate samples and documents, discuss packing and shipping, prevent form abuse, measure inquiry sources and follow up on a business request. Information may also be retained to administer an order, maintain commercial records and resolve a dispute.

Specification files

Files submitted through an inquiry form are attached to the sales inquiry so authorized staff can review specifications, test requirements, packing notes or project images. They are not intentionally published on the website.

Internal and manufacturing support

Inquiry information may be shared with relevant sales, technical, quality, production, packing, logistics or inspection personnel, including Ningxia Yongruida Carbon Co., Ltd., when needed to evaluate or fulfill the request. Information is not sold.

Cookies, analytics and advertising measurement

This website may use necessary browser storage for security or form continuity and optional analytics or advertising measurement tools to understand visits and inquiry conversions. These services may receive device, browser, page, campaign and interaction data. Where required, consent controls will be used before optional advertising storage or personalization is enabled. Browser settings can also be used to restrict or delete cookies.

Service providers and international handling

Website hosting, email, file delivery, analytics, advertising measurement, logistics, inspection or communication providers may process limited information for the requested service. Because DXD Carbon supports international inquiries, information may be handled in China and in the countries where relevant service providers operate.

Security

Reasonable technical and organizational measures are used to limit unauthorized access, disclosure or misuse. Internet and email transmission cannot be guaranteed completely secure, so confidential formulas, passwords, payment credentials or unnecessary personal information should not be submitted through a general inquiry form.

Retention and requests

Business inquiry records are retained as needed for quotation follow-up, order administration, repeat-order context, dispute prevention and applicable legal obligations. You may request access, correction or deletion, or object to marketing follow-up, subject to contractual, security and legal retention requirements.

Policy changes

This policy may be updated when website tools, inquiry processes or legal requirements change. The date above identifies the current published version.
