Yes, we provide free samples of our HSCA (soundless cracking agent) for testing and evaluation.

The sample quantity is usually 1–2 kg, which is sufficient for small-scale testing on your local stone, rock, or concrete materials.

Customers only need to cover the international courier cost (typically via DHL, FedEx, or UPS). This allows engineers and contractors to verify the performance of the expansive mortar / non-explosive demolition agent under real project conditions before placing bulk orders.

Technical documents such as TDS (Technical Data Sheet) and MSDS are also provided with the sample to assist with proper application and safety evaluation.

We accept several international payment methods to make transactions convenient for global customers.

The most commonly used payment terms are T/T (Telegraphic Transfer) and L/C (Letter of Credit) at sight.

For standard orders, we usually require a 30% deposit to start production, with the remaining 70% balance paid before shipment or against the Bill of Lading.

For large orders, long-term distributors, or special projects, payment terms can be discussed based on cooperation history and order volume.

The typical delivery time depends on stock availability and order quantity.

For standard orders of HSCA (soundless cracking agent) or expansive mortar that are in stock, the delivery time is usually 5–10 working days after order confirmation.

If the products need to be produced or for larger bulk orders, the lead time is typically 15–20 days, depending on the order volume and production schedule.
