Who to contact
This website presents Suzhou Hangda Advanced Materials Technology Co., Ltd.. For questions about information you share with the company, contact sales@hd-mag.com.
Cookies and privacy choices
On your first visit, a privacy dialog lets you accept optional cookies, reject them, or set category preferences. Optional categories start off. You can change your choice using in the footer or here. Access to the website and contact information does not depend on accepting optional categories.
The website stores your choice on your current browser in local storage under hangda_privacy_preferences. The record contains the notice version, category choices and the time of your choice. It is used only to remember these settings, is not sent to Hangda by this code, and is valid for 180 days. After that period, or after a relevant notice change, you will be asked again. Clearing browser storage also removes your saved choice. If storage is blocked, the choice applies to the current page and cannot be remembered for later visits.
No analytics scripts, marketing pixels or optional cookies are currently installed by this website. Accepting optional categories does not install any such service. If optional services are introduced, we will update this notice and request a new choice before activating them.
Search terms entered in the search panel and selected comparison grades are remembered in session storage for the current browser tab. This storage code does not send these choices to Hangda. Closing the tab clears the session; browser restore settings may retain it. Product and grade filters may also appear in the page URL so they can be restored when you return.
The Reduce motion control stores only your display preference under hangda_motion_reduced in local storage. It is not sent to Hangda. The setting remains until you change it or clear browser storage; your device’s reduced-motion and data-saving preferences also take priority.
Direct enquiries
This website provides Hangda’s email address, telephone number and factory address. It has no enquiry submission form, drawing upload or email-draft generator. Email links open your email application; they do not send a message automatically. Sending an email shares its content and any attachments you choose to add through your email provider.
Information you choose to send may include your name, business contact details, company, country, application requirements and drawings. These details support responding to your enquiry, technical review and quotation discussions. Contact the company to ask about information in an enquiry you have sent.
Website operation
Hosting and network providers may process technical request information to deliver and secure the website. The privacy choices described above cover the storage implemented by this website; they do not change your email provider or other separate services.
Downloads and external links
Downloads are company documents hosted with the website. The Chinese company website and your email application are separate services with their own operation and information handling.
Updates
This notice should be reviewed when email processing, analytics, website forms or hosting arrangements change. It describes the currently implemented website behaviour.
