Every international shipment from Peptidesr4u.com is accompanied by a complete customs documentation package. The following documents are prepared and enclosed as standard:

Region-Specific Requirements

Import Duties and Taxes

Any import duties, VAT, GST, or other taxes levied by the destination country's customs authority are the sole responsibility of the buyer. Peptidesr4u.com has no control over these charges and cannot predict or guarantee what they will be. We recommend contacting your national customs authority or a licensed customs broker before ordering if you are uncertain of the applicable duties.

Customs Holds and Seizures

Occasionally shipments may be held by customs authorities for inspection. This is normal and does not necessarily indicate a problem. If your shipment is held:

• Contact us immediately at support@peptidesr4u.com with your order number
• We will supply any additional documentation customs may require promptly
• Do not attempt to collect a held package without first consulting us
• In many cases a hold is resolved within 2–5 business days once we provide supporting paperwork

In the event of a permanent seizure or confiscation by customs authorities, Peptidesr4u.com accepts no liability for the loss. No refund or replacement will be issued where a seizure results from the buyer's failure to verify legal import status prior to ordering. Please refer to our Terms of Sale.
