Shipping
Order processing
Orders placed before 12 PM ET ship the same business day when the item is in stock.
Orders after 12 PM ET ship the next business day.
Multiple warehouses & drop-shipments
Many OEM parts ship straight from the manufacturer. Your order may arrive in separate boxes—each with its own tracking number.
If extra freight is required (for example, one brand charges a second shipping fee) we will email the revised total for approval before charging your card.
Estimated rates shown at checkout
Website rates assume standard ground service and parcel-size limits (UPS / USPS / FedEx ≤ 70 lb or 108 inches length + girth).
Oversize or heavyweight items (engines, generators, mixers, etc.) need a freight quote. We’ll contact you first.
Need it faster or have special instructions?
Call or email us before you place the order if you need Next-Day Air, Saturday delivery, Hold-for-Pick-up, or want to ship on your own carrier account. It is not guaranteed but we can certainly try.
Signature / Delivery security
Packages are sent “Signature Not Required” unless you choose otherwise.
DanseUSA is not liable for loss or theft after the carrier marks a package “Delivered,” or for special instructions such as “Leave at back porch.”
Back-orders
If a manufacturer is out of stock we’ll email you. You can keep the order open, swap to an equivalent, or cancel for a full refund.
International, Alaska, Hawaii, Puerto Rico
Rates shown online are only estimates. We will email you final freight and duties for approval. Certain hazardous or oversize items may not be eligible.
Transit damage
Inspect every box before signing. Note any shortage or damage on the driver’s scanner or BOL and tell us within 3 business days so we can file a claim. Damage not noted at delivery voids reimbursement.
Quality check
All products are shipped after complete inspection and thorough quality control from our warehouse.
Limited Warranty
Coverage
DanseUSA passes through the manufacturer’s warranty to the customer, covering defects in materials and workmanship under normal use for 30 days from the date of purchase, in accordance with the manufacturer’s warranty policy.
Exclusions
Misuse, improper installation, modification, neglect, or any condition the manufacturer deems outside normal use voids this warranty.
Manufacturer supersession
If the OEM offers a longer warranty, their terms replace ours. We’ll help you file the claim.
Liability limits
DanseUSA is not responsible for indirect, incidental, or consequential damages, including labor, downtime, or lost profits. DanseUSA shall not be liable for any injury, loss, or damage arising out of misuse, abuse, lack of reasonable care, or misapplication of products.
Filing a claim
RGA required: No warranty returns will be accepted without a return authorization (RGA) number.

What to include: Order number, photos, and a description of the issue.
Return timing: Return the part within 7 days of claim approval using the label we provide. Failure to return within 7 days may be subject to warranty forfeiture.
Returns & Exchanges
Return window
You may return most items within 10 days of the date of purchase if they are unused, uninstalled, and in their original packaging.
Two outcomes
Our mistake (wrong item shipped or mislabeled): You receive a pre-paid return label and a 100% refund, including original outbound shipping.
Customer mistake or change of mind (ordered the wrong part, fit not confirmed, or no longer needed): A 15% restocking fee applies, and you pay the return freight (or we deduct our label cost from the refund).
Avoid the fee

How do I make sure a part fits my machine?
Confirm your model/series and serial number range on the product page. Many manufacturers have serial breaks, when in doubt, share your model and serial with us and we’ll verify fit.
What do the Ref. numbers and quantities mean?
The Ref. # points to the callout on the drawing. Qty shows how many of that item your machine uses. Parts are sold individually unless noted as a kit.
Are these genuine parts?
Yes, we supply genuine OEM parts for all our brands. If a part has an approved replacement, we ship the latest superseded revision.
Why does my original part number look different?
Manufacturers often supersede numbers. Our pages list the current orderable number and show older numbers in the description when available. Your old number will cross-reference to the correct part.
I can’t find a part in this diagram, can you still get it?
Yes. Some items are not pictured or are shared with other assemblies. Send us the model, serial, and a description (or photo) and we’ll locate it.
Is there a warranty on these parts?
Yes. DanseUSA passes the manufacturer’s warranty to you. Coverage applies to defects in materials and workmanship under normal use for 30 days from the purchase date, in line with the manufacturer’s warranty policy. Terms can vary by brand; the product page reflects the applicable policy. If a claim is needed, we’ll help coordinate with the manufacturer.
Do you accept returns?
Yes, most new, uninstalled items can be returned under our standard policy. Please see our Returns & Refunds Policy for eligibility, timeframes, and any exceptions.
