FAQ
Frequently Asked Questions
Helpful answers for your next packaging project.
Are you a U.S. company, and if so, where are your mailing bags manufactured?
Seldravinpack is operated by a U.S.-registered company, with packaging production in China. This allows you direct access to manufacturing capabilities for various materials, colors, sizes, and custom printing. Your order documents will clearly identify the company responsible for your purchase.
How can I assess the quality before placing a large order?
You can request samples to evaluate the material, thickness, color, seal strength, and print quality. Please contact us with the specific products you require, and we will confirm sample availability, costs, and shipping details. For custom orders, all specifications and acceptable tolerances must be agreed upon in writing before production begins.
Can I place a small order to test out a larger purchase?
Yes. You can begin with a small order of our existing stock items to assess their suitability before placing a larger order. Minimum quantities for custom sizes, colors, and printing vary depending on the design. Please let us know your requirements, and we will confirm the minimum order quantity and pricing.
Where will my order be shipped from, and what is the estimated delivery date?
Orders may ship from either the United States or China, depending on product availability and stock. We will confirm the shipping origin, estimated dispatch time, and estimated delivery window for your order. Custom orders also require production time, which will be confirmed separately from the transit time.
Will I be required to pay additional shipping charges or import duties?
Before you make a payment, please review the checkout total or written quotation to confirm shipping charges and applicable taxes. For international orders, we will clarify whether import duties and customs charges are included or are your responsibility. If anything is unclear, please contact us for a complete cost breakdown.
Who receives my payment, and which payment methods do you accept?
Payments are primarily received by our U.S. company. We accept PayPal and direct bank transfers. If you prefer to arrange a personal transfer, please contact us before paying so we can confirm the recipient details and payment instructions. The total amount and payment details will be provided at checkout or on your invoice.
What happens if my bags arrive damaged, faulty, or different from what I ordered?
Please contact us with your order number, the quantity affected, and clear photos of the bags and packaging.
