What customs information needs to be filled out?
Let's start with the options available on the General tab.
Bill Duties and Taxes To
This determines who will pay for any import taxes or customs fees. Choose one of the following:
-
Carrier Default - This applies the option selected in Carrier Settings in Postsale.
- View carrier defaults at Settings > Carrier Settings > Select the carrier account > Click Edit.
- Sender – You, the merchant, pays for customs duties.
- Recipient – The customer pays for customs duties.
- Third Party – Someone else (like a shipping partner) will pay.
- Collect – The recipient must pay upon delivery.
Reason For Export
Why are you shipping this item? Select the correct reason from the drop-down:
- Sold – The item was purchased by the recipient.
- Gift – The item is a personal gift.
- Not Sold – The item is being sent without a sale.
- Personal Effects – Personal items belonging to the sender or recipient.
- Repair and Return – The item is being sent back or repaired.
- Sample – You are sending a sample product.
Customs Content
Select the category that best describes your shipment:
- Merchandise – Products being sold.

Content Description
Many countries require that an accurate description of the contents of the package be included as part of the customs information. It is best practice to always enter an accurate description of the contents of the package, regardless of the destination country.
You should be as detailed as possible. Some countries will not accept a description like ‘Clothes’. Instead, be more descriptive, like ‘Women’s Cotton Sweatshirt'.
Here are a few examples:
| ❌ Invalid Description | ✅ Valid Description |
|---|---|
| Clothes | Women's Cotton Sweatshirt |
| Shoes | Men's Leather Sandals |
| Electronics | 24" Flat Screen Computer Monitor |
Customs Items
Each item within the package must be listed in the Customs Items section. This lets customs officials know exactly what is in the package and gives them the additional information they need to clear the package through customs. The Customs Items section will be populated with the item information from the order.
However, we recommend always reviewing each item listed in the Customs Items section to be sure that each item's information is correct. Select each item and click the Edit button.
If there are any missing items, click the Add button to add them to the list of items.

Here is a list of the information that should be entered for each item in the package:
| Field | What to Enter | Example |
|---|---|---|
| Name | Clearly and accurately describe the item. | Men’s Leather Sandals | Size 12 | Black |
| SKU | (Optional) Enter your product’s SKU number. | MLS12B |
| Quantity | The total number of this item in the shipment. | 1 |
| Unit Price | The cost of one unit. Entered in US dollars. | $45.95 |
| Unit Weight | The weight of one unit. | 3 |
| Unit | Select the correct weight unit of measure. | lbs, oz, kg, g |
| Country of Origin | Select in which country the item was manufactured. | United States of America |
| HS Code | A classification number for customs. We recommend always including the HS Code, regardless of the destination country. | 6402.99.2730 |
Snippet: HS Code Required Callout
HS Codes Required with USPS
Beginning September 1, 2025, the United States Postal Service requires a valid six-digit Harmonized System (HS) code to be included on customs declarations for each item, regardless of mail class, for all international commercial shipments. This update aligns USPS mailing standards with new Universal Postal Union (UPU) regulations.
Let's take a look at a properly entered item.
Notice that the total price and the total weight are calculated for you. This is important because this information is used by customs officials when clearing the package through customs.
