Key Takeaways
- Cargo description syntax now directly affects admissibility outcomes.
- Never use 'Parts' or 'Accessories' alone â ACE requires a qualifying noun (e.g., 'Steel Engine Parts').
- Section 321 Impact: Vague descriptions block ACE auto-routing through PGA checks, pushing entries into manual review even for de minimis shipments.
1. Executive Summary: The Algorithmic Shift
As of 2025, U.S. Customs and Border Protection (CBP) has moved from post-arrival review to pre-departure automated rejection. This shift is implemented via ACE Disposition Code 8H (Invalid Cargo Description Hold) and Disposition Code 6H (Do Not Load).
For logistics developers and customs brokers, data quality in the "Cargo Description" field is now a binary gatekeeper. Generic descriptors like "Parts," "Accessories," or "Daily Necessities" trigger immediate, automated rejection of filings under CSMS #62081967 and CSMS #60144714.
2. Regulatory Architecture & Risk Context
Distinguish between the law, the guidance, and the system behavior:
Statutory Law (The Mandate)
- 19 CFR § 4.7a (Ocean): Requires a precise narrative description of the cargo.
- 19 CFR § 128.21 (Express Consignment): Mandates a specific description for express shipments.
Operational Guidance (The Trigger)
- CSMS #60144714 & #62081967: Establish the vague description crackdown and warning/rejection periods.
System Logic (The Risk)
- Section 321 / Type 86 Impact: Eligibility relies on automated PGA screening. If a description is too vague to rule out PGA jurisdiction (e.g., "Gummies"), ACE cannot auto-route the entry through PGA admissibility checks, which places it into manual review.
-
Enforcement Targets (per CBP public priorities):
- Precursor chemicals / fentanyl: "Daily Necessities" often hides chemical inputs.
- Forced Labor (UFLPA): "Shirts" often hides Xinjiang cotton origins.
3. Technical Architecture: 8H vs. 6H vs. 548
Exception handling logic must differentiate among these codes:
| Code | Type | Meaning | Operational Consequence |
|---|---|---|---|
| 8H | Hold | Invalid Cargo Description | Cargo moves but is held and requires a manifest amendment (Camir YC/X12 309). |
| 6H | DNL | Do Not Load | Critical: Cargo must not be loaded. Fix data pre-departure or incur $5k-$10k damages. |
| 548 | Error | Rejection | The transmission failed entirely; ACE never accepted the data. |
4. The Logic Table: Vague Terms vs. Compliant Fixes
Map common unacceptable terms to compliant alternatives:
These examples reflect CBP informed-compliance doctrine and widely observed ACE validation behavior.
| Vague Term (Trap) | ACE Logic (Why it Fails) | Compliant Alternative (Fix) |
|---|---|---|
| "Parts" | Ambiguous: cannot determine HTS heading or distinguish between safety glass and explosives. | "Steel Machine Parts" or "Automotive Brake Pads" |
| "Electronics" | Ambiguous: could be a radio (FCC) or lithium battery (Hazmat). | "Computer Monitor" or "Wireless Headphones" |
| "Nike Shoes" | Brand-only: identifies who made it, not what it is. | "Nike Brand Tennis Shoes" |
| "Daily Necessities" | Non-identifying: could be toothpaste (FDA) or knives (weapon). | "Plastic Combs" or "Facial Tissue" |
| "Caps" | Ambiguous: multiple HTS possibilities. | "Baseball Caps" or "Plastic Bottle Caps" |
| "Gummies" | Ambiguous: cannot rule out PGA jurisdiction. | "Vitamin C Dietary Supplement Gummies" |
| "Clothing" | Insufficient: fiber content and garment type unknown, raising UFLPA/CPSC screening risk. | "Cotton knit T-shirts" or "Polyester zip hooded tops" |
5. Rapid-Fire Checklist: Avoid These 10 Terms
These everyday phrases trigger ACE 8H or PGA holds because they hide the commodity. Replace them with material + item + intended use before transmitting.
- Parts â always qualify the system or material.
- Accessories â specify the parent product (e.g., âcamera lens accessoriesâ).
- Merchandise â meaningless descriptor; name the item.
- Daily necessities â often hides chemicals or FDA goods.
- Clothing â identify fiber content and garment type.
- Electronics â clarify end-item (tablet, sensor, monitor, etc.).
- Samples â samples of what? describe them.
- Gift â declare the commodity, not the intent.
- Stuff / goods / items â rejected for vagueness.
- Promotional items â describe each promotional sku (e.g., âbranded cotton capsâ).

7. Operational Remediation Protocols
Follow these steps when a hold occurs.
For Code 8H (Hold)
- Audit: Retrieve the exact submitted string.
- Draft: Construct a new description — [Material] + [Item] + [Intended Use].
- Transmit: Send the manifest amendment (Camir YC / X12 309).
- Wait: Monitor for Code 8I (Hold Removed).
For Code 6H (Do Not Load)
- Critical: Do not load cargo. Loading 6H cargo triggers $5k-$10k liquidated damages.
- Correct the data pre-departure and wait for Code 6I (Okay to Load).

Frequently Asked Questions
What is the difference between ACE Disposition Code 8H and 6H?
8H is a 'Hold' placed on cargo that has already departed or arrived; it prevents release until the data is fixed. 6H is a 'Do Not Load' message issued for pre-departure filings (ACAS/ISF), prohibiting the carrier from loading the cargo onto the vessel or aircraft.
Why was my shipment of 'Gummies' rejected?
The term 'Gummies' is ambiguous to the automated system. It could refer to Candy (FDA Food), Vitamins (FDA Supplement), or THC products (DEA/State Law). Because the system cannot determine the regulatory jurisdiction, it rejects the description to force a manual review.
Can I use a brand name like 'Nike' as the description?
No. A brand name identifies the manufacturer, not the commodity. You must describe the item itself. Acceptable: 'Nike Brand Tennis Shoes'. Unacceptable: 'Nike'.
