- DHL waybill number and complete tracking history;
- commercial invoice with seller/shipper, buyer/receiver, currency and true transaction value;
- plain, specific description of each item—not “sample,” “parts” or “gift” alone;
- quantity, country of origin and supporting HS classification information;
- order confirmation and proof of payment when valuation is queried;
- receiver/importer identity or registration required by the destination country;
- permit, prescription, certificate or agency approval for regulated goods, if applicable;
- the DHL request email plus the verified upload/payment route.
Keep every document consistent. Changing value, description or consignee details simply to reduce duty can create a larger compliance problem. If the seller’s invoice is wrong, ask the seller for a corrected commercial document; do not silently edit it yourself.
