Product Q&A

Q:What is the most fundamental difference between 3021 and 3025?

3021 (phenolic paperboard) is for high-volume, low-voltage stamping of simple parts like gaskets. 3025 (phenolic resin fabric board) is for mechanical parts like gears and bearings that need to withstand impact, friction, or vibration.

Q:Are these materials classified as dangerous goods for export?

No, they are not classified as dangerous goods and can be transported as ordinary cargo without special transportation certifications.

Q:What are the payment terms?

We typically use Telegraphic Transfer (T/T), such as 30% deposit and 70% balance against the copy of Bill of Lading. More flexible terms can be discussed for long-term partners.

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

We offer a flexible MOQ policy. Standard products have a very low MOQ, while custom sizes and thicknesses require a higher MOQ based on specific requirements.

Q:What is the lead time?

Standard and in-stock items ship within 7-15 working days. Custom products with special sizes or colors take approximately 15-30 working days depending on order complexity.
