A tax-free price is not reduced again; an unknown basis stays pending.
The 1.5% default is an assumption; cash can be 0. If the rate already includes this fee, do not add it twice.
Default assumption 0; add any shipping, luggage or inbound tax you must pay.

- Same-item basis
- MUJI's Japan official product page's JSON-LD on 2026-09-12 showed ¥299, with the spec line 「ウレタンフォーム三層スポンジ ３個入 約幅６×奥行１２×厚さ３．５ｃｍ 商品番号 44316634」. An exact-JAN search on the Taiwan side (shop.muji.tw's V2/Search?q=4550344316634) matched a product page with the same barcode; the Taiwan page's JSON-LD barcode field is likewise 4550344316634, and the spec 「約寬6*深12*高3.5cm」matches the Japan page item for item. We already confirmed the Japan page is not a Taiwan-market-only listing (the product name has no "（台湾）" prefix, and the page has no "台湾内販" or "ネットストアお取り扱いなし"). US price 2026-09-18: muji.us products.json SKU/JAN 4550344316634 → "Urethane Foam 3-Layer Sponge (3 Pack)" variant "Default Title" $4.90; available=true
