Start with the delivered cost in USD, not the yen listing price. Separate the purchase, proxy service, transport, payment costs and import charges so you can see which amounts are known and which still need checking.
Destination rules to check
Do not assume an order is duty-free merely because it is below US$800. CBP’s current low-value shipment guidance describes the suspension of that exemption. The applicable charge still depends on the entry date, classification, origin and shipping arrangement; a historical “Japan tariff” quoted in a forum is not enough to determine your bill.
Before buying
- Identify the exact product and manufacturing origin. Keep the listing and invoice.
- Search the USITC tariff for the product, then examine applicable additional-duty provisions and effective dates.
- Ask the carrier or proxy whether the quote includes duties, collection fees and clearance. Record what remains payable on arrival.
Worked budget in local currency
Assume US$200 goods, US$12 proxy/payment costs and US$40 transport: the pre-import budget is US$252. Against a US$300 local item, US$48 remains for duty and handling. If verified charges are US$35, the saving becomes US$13. If they are US$60, importing costs US$12 more. No tariff percentage is implied by this example.
Common mistakes for this destination
The calculator supports only the explicitly described planning classifications and origin assumptions. An unsupported item or known different manufacturing origin can leave duty unresolved. Read the item-duty guide, and enter a verified rate only when it represents the applicable combined treatment. A base tariff marked Free alone does not establish a zero total import bill.
Set up the calculator
Choose United States, the item type and marketplace. Enter the local checkout price for an equivalent item. If measurements are unknown, the supported packing assumption is a starting point; update it when the parcel is packed. Use Advanced options for the applicable destination choices and a verified duty rate when needed. Add carrier-specific quotes and extra charges on each route instead of assuming every proxy offers the same shipping price.
How to read estimated savings
Compare against a local price for the same condition, accessories and warranty, including local delivery and applicable tax. LandedCheck can show estimated savings with ordinary inputs when the model supports the destination and item. Read the assumptions beneath the result: an estimate is not a confirmed bill. If duty or another required cost is unresolved, a partial comparison shows the remaining budget before those excluded charges, not final savings. An unavailable shipping route needs a real quote; missing cost is never proof of free delivery.
Keep an evidence folder
Save the seller description, invoice, origin information, shipping quote and tax receipt. When an estimate and a final bill differ, these show whether the difference came from exchange rates, parcel size, valuation, tax collection or an extra service. Ask the operator about a disputed line before treating the difference as a calculator error.
