Frequently Asked Questions by B2B Buyers
Get quick answers regarding minimum order requirements, custom dieline support, international freight options, and manufacturing timelines.
What is the minimum order quantity (MOQ) for custom mailer boxes?
Our minimum run starts at 250 units for custom printed mailer boxes. Ordering in larger tiers (1,000, 3,000, or 10,000+ units) significantly lowers unit cost due to setup optimization on offset and flexographic printing presses.
How do I determine the exact box dimensions for my product?
Provide us with your product length, width, and height, along with weight and fragility considerations. Our packaging engineers will calculate internal tolerances and suggest an ideal box dimension to ensure protection while preventing excess dimensional weight freight charges.
Can you print full CMYK color on the interior and exterior of the mailer?
Yes. We specialize in dual-sided high-definition printing. You can specify different artwork graphics, spot Pantone colors, soy-based inks, or custom thank-you messaging inside the lid for a premium unboxing presentation.
What files are required for pre-press artwork proofing?
We accept high-resolution vector files in Adobe Illustrator (.AI), layered PDF, or EPS format with fonts outlined and 3mm bleed included. We provide a 3D digital PDF proof for sign-off before outputting plate media.
What shipping terms (Incoterms) do you support for export?
We routinely ship under EXW, FOB, CIF, DDU, and DDP terms (Delivered Duty Paid to your door or 3PL warehouse), managing all export documentation, bill of lading (BOL), ISF filings, and customs clearance.
