What this means for your order
- We quote uPVC and fibreglass windows by default. Aluminum-framed windows can pick up both surtax and anti-dumping duty, which can erase the savings.
- Factories that use steel must give us mill certificates showing where the metal was melted. We collect them before your order ships.
- Your quote marks each charge as fixed or estimated. The customs broker’s entry is the final word.
Who is the importer?
LUSSO is. We clear customs on our own account, through our licensed broker, and your order arrives at our warehouse with duty and GST already paid. You don’t need a business number, a CBSA account or any dealings with the border, whether you’re a homeowner or a builder.
Rules change
Surtaxes are reviewed and relief orders expire. If something changes between your quote and your shipment, we tell you before the balance is paid.
