DDP vs DDU: Peptide Import Terms from China Explained
Compare delivered duty paid (DDP) and buyer-cleared (DDU) import models for research peptide shipments from Chinese suppliers.

Introduction
Compare delivered duty paid (DDP) and buyer-cleared (DDU) import models for research peptide shipments from Chinese suppliers.
Peptide From China publishes independent third-party buyer guides for international laboratories sourcing research peptides from China. This is not manufacturer advertising—we help buyers understand supply chain risk before placing orders.
DDP and DDU in Peptide Logistics
DDP (Delivered Duty Paid) means the seller or freight partner arranges export and import clearance through to your address. DDU (Delivered Duty Unpaid) leaves import clearance and duty payment to the buyer.
When DDP Helps
Small labs without a customs broker may prefer DDP quotes that bundle duties. Verify the DDP fee includes all brokerage—not only freight.
When DDU Is Better
Established importers with brokers often clear faster under DDU with accurate paperwork they control.
Documentation Either Way
Both models require accurate COA, invoice, and RUO statements.
Buyer Action Checklist
- - Document your RUO intended use before import
- - Request batch COA with HPLC and MS before payment balance
- - Align invoice descriptions with broker guidance
- - Retain airway bills and batch records in your QMS
- - Use Peptide From China directory to shortlist export-experienced suppliers
