Key sourcing tips
Always order a pre-production sample first to inspect welding, paint finish, bulb brightness and transformer quality.
Confirm voltage and plug standards matching your target country to avoid customs or safety recall issues.
Ask whether the factory can supply custom design drawings and 3D renderings.
Clarify if the quoted price already includes bulbs, transformers, cables and crate packing, as these are often charged as extra surcharges.
Verify the factory’s prior export experience to your target market, such as the US, EU, Middle East or Australia.
