What packaging options are available?

Typical options include 25kg bags, jumbo bags, palletized packaging and customized marks according to customer requirements.

How to choose particle size for plastic filler?

Choose by downstream process, dispersion requirement, mechanical property target and cost structure. D97 and mesh should be checked together.

What does D97 mean for calcium carbonate?

D97 means 97 percent of particles are below a specified size, often used to describe particle size distribution.

Why is whiteness important?

Whiteness affects product appearance, especially in artificial stone, paint, plastic products and other light-colored applications.

Why is moisture important?

High moisture can affect storage, feeding, dispersion and processing stability.

What information is needed for quotation?

Product type, mesh or D97, whiteness, quantity, packaging, destination port, trade terms and contact details help prepare quotation.

What is 1250 mesh calcium carbonate used for?

It is often used where finer particle size and better surface performance are required, depending on formulation.

What is 2000 mesh calcium carbonate used for?

It can be used in applications requiring finer particle size, but suitability depends on D97, whiteness and processing needs.

Is Vietnam GCC suitable for paint?

Vietnam GCC may be suitable for paint and coating when whiteness, particle size distribution and oil absorption meet formulation requirements.

Is calcium carbonate suitable for PVC pipe?

Yes, calcium carbonate is commonly used in PVC pipe, but grade selection should consider particle size, moisture and compatibility.

How does LONGANH support quality control?

We help customers confirm specification items such as particle size, whiteness, CaCO3 content, moisture and packaging inspection.

What ports can be discussed for China shipments?

Customers may discuss destination ports such as Tianjin, Nansha, Xiamen and other China ports depending on logistics plan.

Can trade terms and destination port quotation be discussed?

Quotation terms can be discussed when product grade, quantity, packaging and destination port are clear.

Do you support WeChat communication?

Yes. Contact details include WeChat and WhatsApp for China and overseas customer support.

Is LONGANH a factory or supply chain service provider?

LONGANH Minerals works as a Vietnam mineral powder supply chain service provider connecting factory resources, quality data and export coordination.

How is Vietnam calcium carbonate price calculated?

Price depends on product grade, mesh or D97, whiteness, surface treatment, packaging, order quantity, destination port and case-by-case trade terms.

Can you discuss Tianjin port quotation?

Tianjin port quotation can be discussed after confirming product type, mesh, whiteness, quantity, packaging and shipment schedule.

Can you discuss Nansha port quotation?

Nansha port quotation can be discussed when the buyer provides product specification, packaging requirement, quantity and target delivery schedule.

Can you discuss Xiamen port quotation?

Xiamen port quotation can be discussed after confirming grade, quantity, packaging type, destination port details and current freight conditions.

What is the difference between 325 mesh and 1250 mesh calcium carbonate?

325 mesh is coarser and often used in less demanding filler applications. 1250 mesh is finer and may be used where better dispersion or surface performance is needed.

What is the difference between 1250 mesh and 2000 mesh calcium carbonate?

2000 mesh is finer than 1250 mesh, but buyers should compare D97, application performance, whiteness and cost rather than choosing only by mesh name.

Can you supply 800 mesh calcium carbonate?

800 mesh calcium carbonate can be discussed depending on factory source, target application, whiteness and order quantity.

Can you supply high whiteness calcium carbonate powder?
