FAQ
Q：
What payment methods are accepted for new clients during their initial transaction?
A：
For new clients engaging in their first collaboration with us, we recommend a payment structure consisting of a T/T prepayment followed by the balance paid upon presentation of a copy of the Bill of Lading, or payment via Sight L/C. For small-batch trial orders (typically under a few thousand US dollars), 100% prepayment may be negotiated.
Q：
What should I do if the products encounter quality issues?
A：
Our company places a high priority on customer satisfaction. Should any quality issues arise, please provide relevant evidence promptly (such as photos, videos, third-party inspection reports, warehousing records, etc.). We will actively consult with you—in accordance with the terms of our contract—to negotiate a suitable resolution, which may include returns, replacements, supplementary shipments, or appropriate compensation. For food additives and cosmetic raw materials, we can also assist in tracing the specific production batch.
Q：
Do you provide technical support?
A：
Yes, we do. Our business team possesses specialized expertise in chemistry and can assist clients in addressing inquiries regarding product applications, formulation recommendations, technical parameters, and processing techniques.

Q：
How are hazardous materials transported?
A：
We possess extensive experience in exporting hazardous materials (such as solvents, certain resins, liquid paraffin, etc.). Based on the product's hazard class, we provide compliant hazardous material packaging (UN packaging) and the necessary Hazardous Packaging Certificate, and assist in booking cargo space for hazardous goods to ensure full compliance during shipment.
