Tariff-Smart Shipping — Only at Tuner Depot
NEW! Tariff Protection Plan
During checkout, you’ll have an option to add an additional 10% tariff protection to your order. This will ensure that IF you do receive a tariff or duty charge upon your delivery, we will cover the cost of that bill. You shouldn’t get any extra charges, but if you do, simply reach out to Tuner Depot and supply us with proof of the additional charge and we’ll cover 100% of the charges.
Here’s how it works:
You add the plan.
Customs charges show up? Unlikely, but if they do, send us the bill.
We pay it—every cent.
That means no surprise costs, ever. Customs might flag a package now and then, but with Tariff Protection you’ll never be the one footing the bill. Upgrade with confidence while we handle the paperwork.
