What is your after-sales and warranty policy?

Every order carries a quality warranty: product meets COA spec at delivery, or we replace or credit it. Beyond that, after-sales means partnership — technical support, market documentation and supply continuity.

We treat after-sales as the beginning of the relationship — most of our export customers are repeat buyers. A dedicated account manager stays with you after delivery.
