Terms of Service

Sentol operates strictly as an OEM/ODM manufacturer and wholesaler. We do not engage in B2C (Business to Consumer) retail sales.

• Minimum Order Quantity (MOQ): Private label (OEM) orders require a minimum of 300 cartridges per color.
• Sample Orders: Sample kits are available for quality verification prior to bulk production. Shipping costs for samples are borne by the Buyer.
• Order Confirmation: Production commences only after the deposit is received and artwork/formula specifications are approved in writing.

As a private-label partner, we respect your brand integrity.

• Formulation: We offer standard formulations (Matte, Glossy, Glitter). Custom formula adjustments require R&D review and may incur additional lead time.
• Packaging: Buyer is responsible for providing print-ready artwork files. Sentol is not liable for errors in approved artwork.
• Confidentiality: We do not share your custom designs or client lists with third parties.

Standard trade terms are FOB (Free On Board) unless otherwise negotiated.

Lead times are estimates based on current factory capacity (typically 15-25 days for container loads). We are not liable for delays caused by customs, shipping lines, or force majeure events.

Our products undergo a strict 3-step QC process before leaving the Changsha facility.

• Warranty: We guarantee the shelf life and chemical stability of the product as specified on the technical data sheet (TDS).
• Claims: Any claims regarding quantity or visible damage must be made within 7 days of cargo arrival.
• Limitation of Liability: Sentol is not responsible for installation failures due to improper surface preparation, application errors, or mixing with non-compatible substances. Professional application is recommended.
