Shipping and Delivery
Shipping and Delivery
At JDMuscle, we understand that fast and reliable shipping is crucial. With multiple distribution centers across the nation, most in-stock items are shipped within 1-2 business days. On average, you can expect delivery within 1-5 business days for in-stock items. Please note, however, that some products may ship directly from vendors, which could result in additional delays. Products sourced from overseas may also take longer to arrive.
Free Shipping over $199 Policy
- Free shipping is available only for the 48 contiguous states in the U.S.
- Ground shipping applies to regular-sized items only.
- Oversized items such as lips, hoods, and trunks requiring freight shipping are not included in the free shipping program.
- Some manufacturers may impose a shipping surcharge, which will be excluded from the free shipping program.
- The most accurate shipping costs will be displayed at checkout. If you believe the shipping cost is incorrect, please contact us at sales@jdmuscleusa.com for further review.
Carriers
We ship via FedEx, UPS, USPS, and DHL. While we strive to use the most efficient option, we cannot guarantee which carrier will deliver your order. Your items may arrive in multiple packages through different carriers.
Processing Time and Shipping Cut-off
Orders typically take 24 hours to process, with shipping cut-off at 3:00 PM EST. Transit times vary based on location and carrier. Some items, especially those requiring freight shipping, may have extended processing and delivery times. For freight shipping inquiries, contact us at sales@jdmuscleusa.com.
International and Special Shipping Considerations
- 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.
- Customers can challenge and request a review of international shipping fees, and weβll do our best to find a lower rate where possible.
- Customs Fees & Import Taxes: The shipping charge you pay does not include customs fees or import taxes. These charges vary by country and are the customerβs responsibility. Please check with your local customs office for more details before placing an order.
- Shipping Cost Adjustments: Shipping rates fluctuate, and while we strive to provide the most competitive rates, there may be instances where the shipping cost you paid is significantly lower than the actual cost. In such cases, we reserve the right to request the difference to ensure we cover our basic expenses. We appreciate your understanding and will always aim to keep shipping costs as affordable as possible.
Address Modifications and Fees
- Any modifications to a shipping address after an order is placed may be subject to additional fees.
- For single, small packages, the flat fee is $20. For larger or multiple packages, the fee may be up to $60 or more.
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.
Package Protection
We do our best to ensure your items arrive to you safely but sometimes things happen. If you utilized our Checkout+ feature, rest assured that your package is protected! With package protection, in the event that your package is lost, stolen, or damaged while in transit, we will replace it free of charge. To start a shipping claim, please click here.
