Product Q&A

Q:How do you handle transportation?

Chemical products are generally transported by sea via full containers. For quantities below full container requirements or special products, we combine them with other goods or pack them separately. Packing methods are confirmed after placing the order.

Q:Is the product quality stable?

Yes. We cooperate with large-scale Chinese factories, inspecting them and purchasing samples before cooperation. Only products complying with national regulations are accepted. Exported goods undergo additional inspection, and non-compliant items are rejected.

Q:Are there discounts for large quantity purchases?

Yes, large customers receive more favorable prices. However, specific quotations vary by chemical type, so you need to consult customer service for the latest pricing.

Q:What is the Minimum Order Quantity (MOQ)?

The minimum order quantity is 1 ton. Orders are shipped via LCL (Less than Container Load) combined with other goods, except for special chemicals.

Q:Do you provide free samples?

We do not provide free samples currently. However, we provide quality testing reports and other certifications to ensure our quality matches high-quality market products.
