FAQ

Common buyer questions

Do you ship to the United States?

Yes. The US is our primary export market. We ship by sea, air or courier depending on order size, and quote freight together with the product price so you see the landed cost before committing.

What is your MOQ?

MOQ varies by product, material, production process, packaging and customization. We confirm it after reviewing your RFQ instead of applying one number to every project.

How long does sample and bulk production take?

Timing depends on the product, tooling, material availability and inspection requirements. The quotation should separate sample timing, approval time and production timing.

Can you support OEM and ODM orders?

Yes. SINAWATTS supports logo, color, size, packaging and material customization for overseas wholesalers, importers, distributors and contractors.

Which certifications are available?

Required certificates and test reports must be checked against the exact model, specification and destination market. We confirm document availability for each project before order approval.
