Standard lead time is 10-15 days for production after deposit confirmation, plus shipping time. Sea freight to most major ports is 20-35 days depending on destination. Air freight is 5-7 days. We also offer expedited production for urgent orders.

Do you provide free samples?

Yes, we provide free samples (1-2 kg) for quality evaluation. Customer is responsible for courier charges (DHL/FedEx/TNT), which can be deducted from your first formal order. Sample lead time is 3-5 days.

Can you match custom colors?

Yes, we offer full custom color matching service. Please provide a color sample, RAL/Pantone code, or detailed description. Our lab will match the color and provide a sample for approval within 5-7 working days. Custom colors typically require MOQ of 500 kg.

How do water-based coatings compare to solvent-based?
