Tariff Considerations in Supplier EDI: What You Need to Know to Succeed

Overview

Tariff accuracy isn’t merely a compliance issue; it’s a business efficiency imperative. For suppliers, providing complete and correct tariff-related data in EDI transactions streamlines customs clearance, reduces costly delays, and accelerates customer payments.

We offer practical guidance on the key EDI documents and data elements suppliers must get right to facilitate smooth border crossings, ensure compliance with U.S. Customs and Border Protection regulations, and maintain strong customer relationships.

Why Tariff Accuracy in EDI Matters

When suppliers send accurate tariff information in key EDI documents like the 856 (Advance Ship Notice) and 810 (Invoice), it enables customers to generate accurate customs documentation. That means:

• Faster border crossings
• Fewer customs fines
• Faster payments from customers

Tariff Information in Supplier EDI Documents: What to Include

Customs and Border Protection (CBP) requires accurate product classification using the Harmonized Tariff Schedule (HTS). Tariffs are calculated based on a product’s HTS and the total value, so accuracy is vital. Quick border crossings depend on correctly classified products and the inclusion of accurate HTS codes, quantities, and pricing in your EDI documents.

Key Tariff-Related Data for EDI Documents

• 856 (Advanced Ship Notice)
  • N1 or REF Segment – Provide the product’s country of origin to help customers qualify for duty-free exemptions.
  • LIN Segment – Use “HD” qualifier to send the HTS code.
  • SN1 Segment – Include the correct shipped quantity and unit of measure.
  • SLN Segment – Use “HD” qualifier at the item-level when necessary.
  • REF Segment – Use “ZHS” qualifier to indicate the HTS code.

• 855 (Purchase Order Acknowledgment) and 865 (Purchase Order Change Acknowledgment)
  • PO1 Segment – Include “HD” qualifier to send the HTS code. This is generally only necessary if your customer used an incorrect code in their 850 Purchase Order and you need to provide a correction.

• 810 (Invoice)
  • IT1 Segment – Include accurate item price, quantity, and unit of measure.
  • N1 or REF Segment – Provide country of origin, when required for customs and trade compliance.
  • SAC Segment – Consider using this to communicate separate tariff charges instead of modifying the unit price. This provides flexibility and a faster turnaround when tariffs change.

Efficient Customer Communication is Key

Tariff implications can cause rapid shifts in pricing and sourcing. Suppliers must be able to communicate changes quickly through EDI. Depending on your capabilities and your customers’ requirements, options for communicating changes include:

• 855 Purchase Order Acknowledgment
• 865 Purchase Order Change Acknowledgment
• 832 Price/Sales Catalog or 845 Price Authorization Acknowledgment
• 879 Price Information

Use these documents to notify customers of:

• Tariff-related price adjustments
• Product substitutions
• Updated origin or classification data

Providing proactive updates builds trust with suppliers which leads to smoother order fulfillment cycles.
