In brief: Do not return dental products without written authorization. Report visible freight damage within 48 hours, shortages or incorrect items within seven calendar days, and other quality concerns promptly within the warranty or claim period stated for the product. Open sterile, single-use, custom or hygiene-sensitive goods normally cannot be returned.
1. Scope
This policy applies to B2B purchases in which the seller is identified in a Lingheng quotation, PI or sales contract. If that document contains a different return, inspection, warranty or claim term, the transaction document controls.
2. Contact us before returning anything
Email or message us with the PI/invoice number, SKU, quantity and reason. We will review eligibility and, when approved, provide return instructions. Unauthorized returns may be refused, delayed or returned at the sender’s cost.
3. Claim deadlines
| Issue | Notify us | Evidence |
|---|---|---|
| Visible carton or freight damage | Within 48 hours of delivery | Carrier notation, carton/label photos, item photos |
| Shortage, wrong SKU or packing discrepancy | Within 7 calendar days | Unboxing photos/video, packing list, quantity count |
| Nonconformity or suspected defect | Promptly after discovery and within the applicable product/contract period | Lot/batch, label, photos/video, description and storage/use details |
| Unused standard-item return request | Within 14 calendar days of delivery | Sealed condition, invoice and reason |
A later notice may still be reviewed for a latent defect or mandatory legal right, but delay can limit carrier recovery or verification.
4. Items normally not returnable
- opened, used, contaminated or patient-contact products;
- sterile or single-use goods with opened, damaged or altered packaging;
- expired, temperature-abused or improperly stored products;
- custom, printed, OEM, private-label, special-order or discontinued items;
- goods altered, relabeled or repacked by the buyer;
- items restricted from cross-border return by carrier, customs or safety rules.
5. Condition of approved returns
Approved standard-item returns must be unused, complete, resalable and in original sealed packaging with lot/label information intact. Pack the goods to prevent further damage and follow the provided routing and customs instructions. The buyer pays return freight and related charges unless the return results from a verified seller error or accepted defect.
6. Evidence needed for a claim
- quotation/PI or invoice number;
- SKU, quantity and affected quantity;
- outer carton, shipping label and seal photographs;
- product label, lot/batch and expiry photographs when applicable;
- clear images or video showing the issue;
- delivery date, storage conditions and concise description of discovery;
- carrier damage report when transit damage is involved.
Do not send patient-identifiable or health information.
7. Review and remedies
We may ask for samples, additional images, manufacturer review or independent inspection. For an accepted claim, the available remedy may be replacement, repair where appropriate, credit or refund for the affected goods, as agreed and subject to the transaction terms. Freight, duty and consequential loss are handled according to the PI, Incoterm and applicable law.
8. Product safety concerns
Stop using any product that may present a safety or labeling concern, isolate the affected lot and contact us promptly. Preserve packaging and traceability information. We will coordinate available manufacturer investigation and any legally required action.
