What is PS Form 6183?
PS Form 6183 (Commercial Invoice for OCPI) is an official United States Postal Service document required for commercial shippers utilizing the Outbound Commercial Provider Initiative.
Think of it as the passport for your commercial goods. Customs officials in the destination country use this exact document to assess duties, verify the legality of the shipment, and clear your items for final delivery. Without a properly completed PS 6183, your shipment risks severe delays, return to sender, or confiscation.
Important Deadline Note: This form must be completed and attached before handing your shipment over to USPS. It cannot be filed retroactively once the package is in transit.

Section-by-Section Walkthrough

Sender & Addressee Information
This section establishes the two parties in the transaction. You must provide complete physical addresses (no P.O. Boxes for international commercial shipments unless explicitly allowed by the destination) and valid contact numbers.
⚠️ Pro Tip: Ensure the company name matches exactly with your business registration to avoid hold-ups.
Itemized Goods & HTS Codes
This is the most critical part of PS 6183. You must list every distinct item in the package. "General merchandise" or "gifts" will trigger automatic rejections on commercial invoices.
- Description: Be specific (e.g., "Men's 100% cotton t-shirt" not "shirt").
- HTS Number: The 6-to-10 digit Harmonized Tariff Schedule code.
- Value: Must reflect true commercial value, even if providing samples.
