    Sealock manufactures waterproof bags for OEM and wholesale buyers from factories in Dongguan, China and Ho Chi Minh City, Vietnam, with either origin available on any model in the range. For importers, the origin decision changed twice in 2026 and most sourcing advice online is now out of date — including the widely repeated claim that Vietnam is duty-free. This sets out what actually applies, how to calculate it for bags, and what determines origin when a supplier operates in both countries.

  • Waterproof Bag Packaging and Retail Presentation for OEM Buyers

    Sealock produces waterproof bags for OEM and wholesale buyers with packaging specified to the sales channel, from plain export cartons through to retail-ready and marketplace-compliant presentation.

This covers what to specify, what each channel requires, and what changed in 2026.

  • Dry Bag MOQ Explained: Minimum Order Quantities for OEM Projects

    Sealock is a dry bag manufacturer running OEM and wholesale projects at an MOQ of 300 pieces, and the minimum order quantity is the number that surprises the most first-time buyers. MOQ is not a barrier a factory invents to exclude small brands — it is a calculation tied to material sourcing and production economics, and understanding what drives it is exactly what lets a buyer negotiate it intelligently rather than just asking for a lower number. This explains why dry bag MOQs land where they do, what moves them, and how to work with them on an OEM project.

  • Waterproof Bike Bag Supplier from China

    Sealock is a waterproof bike bag supplier and OEM manufacturer serving cycling brands, bikepacking labels, and distributors from factories in China and Vietnam. Sourcing bike luggage carries a risk no other bag category has: a bag can be flawlessly manufactured — perfect welds, clean stitching, correct materials — and still be a total loss, because it does not fit the bike. Fit is the failure mode here, and it is what supplier vetting in this category has to be built around.
