Product Q&A

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

3021 (phenolic paperboard) is for high-volume, low-cost stamping in low-voltage environments without impact resistance. 3025 (phenolic resin fabric board) is for mechanical parts like gears and bearings that require impact, friction, or vibration resistance while meeting insulation needs.

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 the 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. Please provide specific requirements for confirmation.

Q:What is the lead time for orders?

Standard and in-stock items are shipped within 7-15 working days. Custom products (special sizes, colors, etc.) typically take 15-30 working days depending on order complexity.
