Product Q&A
Q:What is the most fundamental difference between 3021 and 3025?
A:
3021 (phenolic paperboard) is for high-volume, low-cost stamping of simple parts in low-voltage environments. 3025 (phenolic resin fabric board) is for mechanical parts like gears and bearings that require higher impact and vibration resistance.
Q:Are these materials classified as dangerous goods for export?
A:
No, they are not classified as dangerous goods and can be transported as ordinary cargo without special certifications.
Q:What are the payment terms?
A:
We typically use Telegraphic Transfer (T/T) with 30% deposit and 70% balance against copy of Bill of Lading. More flexible terms can be discussed for long-term partners.
Q:What is the Minimum Order Quantity (MOQ)?
A:
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 for delivery?
A:
Standard and in-stock items ship within 7-15 working days. Custom products typically take 15-30 working days depending on order complexity.
