Shipping a package internationally usually requires more than an address label. This reusable checklist explains which customs forms, commercial invoices, identification details, and supporting documents may be needed, depending on what you are sending, why you are sending it, and where it is going.
Overview
International shipping documents help the carrier, customs authorities, and the recipient understand what is inside a parcel and how it should be handled. Requirements vary by origin country, destination, carrier, shipment type, merchandise value, and the intended use of the goods. A private gift, a returned purchase, and a commercial sale may need different information even when the package contains similar items.
Before preparing the parcel, confirm the destination country's rules and the shipping service's document requirements. Carrier forms and electronic customs systems may use different names, but the underlying information is generally similar: sender and recipient details, an accurate description of each item, quantity, weight, value, country of origin, and the reason for export.
Do not assume that a tracking label replaces a customs declaration. A label identifies the shipment for delivery; customs documentation describes the contents for border processing. Missing, vague, or inconsistent information can lead to questions, delays, additional charges, return to sender, or refusal of the shipment.
Checklist by scenario
Use the scenario that best matches your shipment, then check the carrier and destination authority for any additional requirements.
| Shipment scenario | Documents and information to prepare | Extra points to check |
|---|---|---|
| Personal gift or household item | Customs declaration, sender and recipient contact details, plain-language item description, quantity, weight, and honest value | State that it is a gift only when that is accurate. Check destination rules for gifts, food, medicines, and used goods. |
| Online sale or commercial shipment | Customs declaration, commercial invoice, seller and buyer details, itemized contents, sale value, currency, country of origin, and shipping terms when requested | Keep a copy of the order and invoice. The declared value should match the transaction records and the information submitted electronically. |
| Return to a retailer or repair center | Return authorization or reference, customs declaration, description of the original goods, and any carrier or merchant return form | Explain that the parcel is a return or repair shipment if the form provides that option. Follow the retailer's instructions about duties and taxes. |
| Documents or printed material | Shipping label and any required customs declaration; a commercial invoice may still be requested if the contents have a sale value | Do not describe merchandise as documents merely to avoid customs processing. |
| Food, cosmetics, plants, medicines, or regulated goods | Customs declaration plus any permits, certificates, prescriptions, ingredient information, or safety documents required for the specific item | Check both import restrictions and carrier acceptance rules before packing. Some goods may be prohibited even when personal use is intended. |
| High-value, fragile, or specialized goods | Detailed commercial invoice or proof of value, accurate classification information where required, and insurance or valuation records if purchased | Confirm whether the carrier requires extra packaging, signatures, identity checks, or export documentation. |
For most merchandise shipments, prepare these core details before opening the carrier form:
- Full sender and recipient names, physical addresses, and reachable contact details.
- A specific description for every item, such as “cotton T-shirt” rather than “clothes” or “gift.”
- Quantity, unit value, total value, currency, net or gross weight as requested, and country of origin.
- The reason for export, such as sale, gift, personal effects, return, or repair.
- Any product, tariff, permit, or identification information requested by the carrier or destination authority.
- A copy of the completed declaration, invoice, receipt, and tracking details for your records.
What to double-check
Destination and carrier requirements
Review the official guidance for the destination and the exact service you plan to use. Postal services, express couriers, and freight providers can collect similar information through different forms or electronic workflows. If the carrier offers online customs preparation, enter the information there and print or attach any pages it instructs you to include.
Descriptions and values
Use ordinary language that identifies the item, its material or purpose when relevant, and its quantity. “Two wool scarves” is more useful than “accessories.” Declare the actual transaction or replacement value required by the form. Marking a sale as a gift, understating the value, or using inconsistent currencies can create problems for the recipient and may invalidate shipping or insurance information.
Prohibited and restricted goods
Check restrictions before you buy postage. Common areas requiring extra attention include batteries, aerosols, liquids, flammable materials, perishables, plants, animal products, medicines, supplements, weapons, and valuable items. A good may be legal to possess but restricted for transport or import. When rules are unclear, ask the carrier or the relevant destination authority before handing over the parcel.
Duties, taxes, and recipient information
Customs documents do not normally guarantee that no duties or taxes will be charged. The recipient may be contacted for payment, identification, or additional information. Tell the recipient what to expect without promising a particular amount or delivery date. For tracking help after dispatch, see what to check when a package is stuck in customs.
Common mistakes
- Using vague descriptions: “samples,” “parts,” or “present” does not adequately identify many goods.
- Leaving fields blank: If a field does not apply, use the form's permitted option rather than guessing or omitting required information.
- Making documents disagree: The label, customs declaration, commercial invoice, order record, and package contents should tell the same story.
- Confusing country of origin with shipping origin: These can be different. Enter the information requested by the form accurately.
- Attaching paperwork where it cannot be seen: Follow the carrier's instructions for document pouches, labels, and copies retained by the sender.
- Assuming a tracking number means customs clearance: Tracking may show that a shipment is moving while customs review or a document request is still pending.
- Sending restricted goods without checking: Do not rely on a previous shipment as proof that the same item is currently accepted.
After dispatch, keep the receipt and monitor the tracking record. If the number is not recognized, first confirm that you are using the correct carrier and that the shipment has entered the carrier's system.

When to revisit
Use this checklist before every international shipment, not only when sending to a new country. Recheck it when the contents change, when you switch from a postal service to a courier, when you begin selling commercially, or when a shipment includes a regulated product. It is also worth reviewing before seasonal shipping periods, when carrier workflows may change, and whenever the destination or origin authority updates its customs instructions.
For a practical final check, pause before sealing the parcel and confirm five things: the carrier accepts the contents; the recipient's address and contact details are complete; the declaration describes every item accurately; the value, currency, and reason for export are consistent; and all requested forms or permits are attached in the required place. Save copies of the documents, then use the tracking number to monitor delivery and respond promptly if the carrier or customs office requests more information.
