and communicate to prevent rejections, avoid, delays, U.S. tariffs and EU ICS2 enforcement are creating a dual-layer customs risk for LSPs. Here’s what you must file

New U.S. tariff rules went live on April 2, 2025, and logistics service providers (LSPs) are already seeing ripple effects in customs systems. One of the most immediate problems? HTS code mismatches and EDI rejections.

If you’re seeing unusual entry errors, customs holds, or manual review requests — you’re not alone. The sudden reclassification of imported goods under Trump’s “Liberation Day” reciprocal tariffs is overwhelming systems like CBP ACE and creating confusion across freight and compliance teams.

What Changed with HTS Codes on April 2 — And Why It Matters

As part of the White House’s new trade policy, U.S. Customs and Border Protection (CBP) has begun enforcing reciprocal tariffs tied to the country of origin. That means:

New tariff rates are now applied based on bilateral trade relationships
HTS classifications must be reviewed and updated for compliance
Goods from China, the EU, Mexico, and Canada now face new duty levels (up to 34%)

The challenge? Most customs platforms are not instantly updated with these new rules. As a result, LSPs are being hit with entry rejections, additional documentation requests, and manual clearance delays.

Why EDI Errors Are Rising Across U.S. Customs

Electronic Data Interchange (EDI) is how LSPs transmit shipment information to customs — including bills of lading, invoices, entry summaries, and classification data. Under normal conditions, this system is fast and automatic. But right now?

Customs officials are flagging a wave of errors as automated EDI feeds clash with the newly updated tariff logic. The most common breakdowns include:

Outdated HTS codes triggering rejections in CBP’s ACE system
Unmapped reciprocal tariff rules leading to missing or incorrect duty data
Document mismatches (e.g. invoice values vs. declared entry) leading to holds

According to recent feedback from trade compliance officers, entry rejection rates have spiked post-April 2, especially for shipments originating in China, the EU, and Latin America.

What to Communicate With Clients (Before They Ask)

Client trust hinges on proactive updates — especially during periods of policy volatility. Don’t wait for clients to flag missed ETAs or delayed clearances. Here’s what to include in your outreach:

Flag possible delays: Be transparent about customs hold risks due to HTS reclassification or ICS2 entry rejections.
Share mitigation plans: Let clients know you’re auditing entries and have escalation workflows in place.
Offer classification support: Help clients validate HTS and product descriptions pre-submission.
Set realistic expectations: Adjust SLAs, lead times, and pricing based on new compliance demands.
