International orders are subject to higher shipping fees. If you would like to review your shipping cost, email us at sales@jdmuscleusa.com with your full address and items you plan to purchase.

In some cases, shipping costs may be incorrectly calculated for international or oversized items. We reserve the right to adjust the shipping fee and will work with you to negotiate a fair cost if needed.

In such cases, we reserve the right to request the difference to ensure we cover our basic expenses.

Freight Shipping Guidelines

Freight shipments require you to be present at the time of delivery.

The delivery driver may provide a delivery receipt (Bill of Lading). It is crucial to inspect the shipment before signing.

Carefully check the packaging for any visible damage (dents, punctures, rips) and notate it on the Bill of Lading.

Open the package and inspect the product itself. If damage is found, document it in detail on the Bill of Lading, take photos, and contact the shipping company to initiate a damage claim.

Do not refuse the shipment. Contact us at sales@jdmuscleusa.com for guidance.

If the delivery driver is unable to wait for inspection, note this on the Bill of Lading.

Failure to document damages before signing the Bill of Lading will void any claims for refunds or replacements.

Pre-Installation Inspection Policy

We strongly recommend inspecting all parts or items upon arrival before installation. If you identify any damage, imperfections or missing components, report them immediately to sales@jdmuscleusa.com. Do not install the item. Please note that reports of damage, defects, imperfections or missing components after installation will NOT be honored.
