Product Q&A
Q:What is the most fundamental difference between 3021 and 3025?
A:
If your needs are: high-volume, high-efficiency stamping of uniformly shaped parts (such as gaskets, label holders, simple frames).The product is primarily used for electrical insulation in low-voltage environments. If you are extremely cost-sensitive and do not require parts to withstand impact or bending forces, you should choose 3021 (phenolic paperboard). If your needs involve turning or milling materials into mechanical parts such as gears, bearings, bushings, and handles, and these parts n
Q:Are these materials classified as dangerous goods for export?
A:
It is not classified as dangerous goods and can be transported as ordinary cargo.
Q:What are the payment terms?
A:
We typically use Telegraphic Transfer (T/T), e.g., 30% deposit, 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. For standard products, the MOQ can be very low. For custom sizes and thicknesses, the MOQ will be higher accordingly. Please provide your specific requirements for confirmation.
Q:What is the lead time?
A:
For standard and in-stock items, shipment is typically within 7-15 working days. For custom products (special sizes, colors,etc.), the lead time is approximately 15-30 working days, depending on the order complexity.
