Before Ordering
〇 About Import Consumption Tax At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout. 〇 Confirmation of Compatibility Our entire product database is based on North American vehicles (USDM). Please confirm whether or not the product can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.) If you order without confirming compatibility, we cannot accept returns due to incompatibility. Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model on the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification. All product descriptions have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions. ○ Regarding Shipping Shipping costs are paid at the time of checkout. Shipping cost estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual shipping cost. In such cases, we will contact you individually via email. In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for your order. If you are in a hurry, please inquire about delivery times in advance. All products are transported via air freight. They are not shipped by sea. ○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility Essentially all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk. ○ Regarding Warranty Please check the contents immediately upon arrival of your order. Since all products are shipped internationally from outside Japan, there is a possibility of damage to the packaging box or the product during transit. We will provide returns, refunds, or replacements for products with shipping damage, defects, or incorrect items only if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty support will be handled "exclusively through our company." Please note that we do not coordinate with other companies or agencies located within Japan.
