Frequently Asked Questions

Who is TDHX Minerals and where is the factory?

tdhxtrade.com is operated by Dalian Taiding Hengxin International Trade Co., Ltd. (established 2021), the export arm of Haicheng Taiding Huaxin Mineral Products Processing Co., Ltd. — a non-metallic mineral processing plant in Yingluo Industrial Park, Haicheng City, Liaoning, China, with roots dating back to 1990 and a 20,000 m² production site.

Which minerals do you produce and export?

Talc powder (200–3000 mesh), ground calcium carbonate powder and calcite sand (10 mesh–2500 mesh), dolomite powder (200–2500 mesh), magnesia products including caustic calcined, dead burnt and electro-fused magnesia plus magnesium sulphate, snow white sand, and coloured landscaping pebbles.

Can you produce to our own specification?

Yes. Whiteness, SiO₂ / CaCO₃ / MgO content, D50 and D97 particle size, pass rate, moisture and packaging are all adjustable against your specification. Send your target figures and we will confirm feasibility with a TDS and a free sample.

What is the minimum order quantity and lead time?

Trial orders from one 20 ft container (25–27 tonnes) are welcome. Samples are free of charge. Bulk production typically takes 7–15 days after the specification and artwork are confirmed.

Which ports do you ship from and what payment terms do you accept?

We ship from Dalian and Yingkou in Liaoning Province, or any Chinese port nominated by the buyer. Payment terms include T/T and L/C at sight; other terms can be discussed for repeat business.

Do you provide test reports?

Every batch is tested in-house and shipped with a batch certificate. We can also arrange SGS or equivalent third-party inspection before shipment at the buyer's request.
