9.5 "Customs Business" Defined and Unlicensed Practice

Key Takeaways

  • 19 CFR 111.1 defines customs business as those activities involving transactions with CBP concerning the entry and admissibility of merchandise, its classification and valuation, and the payment of duties, taxes, or other charges, including the preparation of documents and the electronic transmission of documents and data intended to be filed with CBP.
  • Customs business expressly excludes the mere electronic transmission of data received for transmission to CBP, and it excludes corporate compliance activity.
  • Corporate compliance activity is activity performed by a business entity to ensure that documents for a related business entity are prepared and filed with CBP using reasonable care, but it does not extend to the actual preparation or filing of those documents.
  • Under 19 U.S.C. 1641(b)(6), a person who transacts customs business other than as provided in the statute is liable for a monetary penalty not to exceed $10,000 for each transaction and not to exceed $30,000 in total.
  • An unlicensed freight forwarder has no right to make entry and cannot execute a customs power of attorney appointing a broker on behalf of the actual owner or purchaser.

9.5 "Customs Business" Defined and Unlicensed Practice

Why the definition is worth memorizing: the license requirement, the responsible supervision obligation, the fee-splitting prohibition, and the unlicensed-practice penalty all hinge on a single defined term. If an activity is customs business, only a licensed broker may perform it for others; if it is not, anyone may. 19 CFR 111.1 draws the line.

The Definition (19 CFR 111.1)

Customs business means "those activities involving transactions with CBP concerning the entry and admissibility of merchandise, its classification and valuation, the payment of duties, taxes, or other charges assessed or collected by CBP upon merchandise by reason of its importation, or the refund, rebate, or drawback of those duties, taxes, or other charges."

The definition then extends to preparation and transmission:

It "also includes the preparation, and activities relating to the preparation, of documents in any format and the electronic transmission of documents and parts of documents intended to be filed with CBP in furtherance of any other customs business activity, whether or not signed or filed by the preparer."

Break that into its operative elements:

ElementConsequence
Transactions with CBP concerning entry and admissibilityFiling entries, responding to CBP Forms 28 and 29, filing protests and drawback claims
Classification and valuationDetermining the HTSUS subheading or the appraised value for a client
Payment of duties, taxes, or charges, and their refund, rebate, or drawbackHandling duty funds, filing drawback claims
Preparation of documents, in any formatReaches the preparer even if someone else signs and files
Electronic transmission of documents intended to be filed with CBPReaches ABI transmission of substantive data

The phrase "whether or not signed or filed by the preparer" is the reason a service bureau cannot escape the license requirement by having the importer sign. The act of preparation is itself customs business.


The Two Exclusions

1. Mere Electronic Transmission of Data

The definition excludes the "mere electronic transmission of data received for transmission to CBP." This carve-out protects the pure conduit: a value-added network, a software provider, or a service bureau that receives completed data from a party and passes it to CBP without preparing, reviewing, classifying, valuing, or correcting it. The moment the transmitter starts making substantive determinations — selecting a classification, computing an entered value, deciding what charges are dutiable — it is no longer mere transmission and the exclusion falls away.

2. Corporate Compliance Activity

The definition also excludes corporate compliance activity, which 19 CFR 111.1 defines as:

"activity performed by a business entity to ensure that documents for a related business entity or entities are prepared and filed with CBP using 'reasonable care,' but such activity does not extend to the actual preparation or filing of the documents or their electronic equivalents."

Two limits are built into that sentence, and questions are constructed on both:

  • "Related business entity." The exclusion covers activity for entities related to the one performing it. A corporate trade-compliance department overseeing its own affiliates' filings is inside the exclusion; a firm performing the same oversight for unrelated clients is not.
  • "Does not extend to the actual preparation or filing." The exclusion covers oversight — writing procedures, training staff, auditing entries after the fact, setting classification policy. The instant the compliance department prepares or files the document itself, it has crossed into customs business.

THE PRACTICAL LINE: An in-house compliance manager at a manufacturer may build the classification database, write the reasonable-care procedures, and audit the broker's work for the company and its affiliates. The same manager may not prepare entries for an unrelated supplier, and may not hold out those services to third parties.


Activities That Are Not Customs Business

A broker may compensate an unlicensed freight forwarder or logistics provider for these, under a written agreement and at compensation not derived from customs business (19 CFR 111.36):

  • Arranging international and domestic transportation and booking cargo;
  • Tracking arrival notices and container availability;
  • Assembling and forwarding commercial documents without preparing entry data;
  • Coordinating terminal delivery, cartage, and warehousing;
  • Clerical sorting and copying of documents.

Contrast these, which are customs business and may be performed for others only by a licensed broker:

  • Determining an HTSUS classification or an appraised value for a client;
  • Preparing or transmitting entry, entry summary, protest, or drawback data;
  • Advising a client on admissibility, marking, or preference eligibility;
  • Receiving and disbursing client funds for duties, taxes, and fees;
  • Responding substantively to a CBP request for information.

The Penalty for Unlicensed Practice

19 U.S.C. § 1641(b)(6) provides that any person who intentionally transacts customs business, other than as provided in the section, without holding a valid license is liable for a monetary penalty not to exceed $10,000 for each such transaction, and not to exceed $30,000 in total. Note the structure: a per-transaction figure with an aggregate cap. Compare it with the penalty reaching a licensed broker for violating Section 641 or Part 111 — 19 U.S.C. § 1641(d)(2)(A), a penalty not to exceed $30,000 in total for the violation or violations, with no per-transaction component.

ProvisionWhoStructureCeiling
19 U.S.C. § 1641(b)(6)A person transacting customs business without a licensePer transaction, with an aggregate cap$10,000 per transaction / $30,000 total
19 U.S.C. § 1641(d)(2)(A)A licensed broker violating Section 641 or 19 CFR Part 111Aggregate only$30,000 in total

A licensed broker also risks suspension or revocation under 19 CFR Part 111, Subpart D, and 19 CFR 111.53 makes it a ground for discipline to knowingly employ, or to conduct business with, a person whose license has been revoked or who has been convicted of a felony.


The Right to Make Entry Corollary

The definition of customs business intersects with the right to make entry. Under 19 U.S.C. § 1484, 19 CFR 141.11, and CBP Directive 3530-002A, entry may be made only by the owner or purchaser of the merchandise, or by a licensed broker appointed by the owner or purchaser. Two consequences follow for an unlicensed intermediary:

  1. It cannot be the importer of record merely because it appears as consignee on a bill of lading. A nominal consignee with no proprietary interest has no right to make entry.
  2. It cannot execute a power of attorney appointing a broker on the actual owner's behalf. The chain of authority must run from the owner or purchaser. A broker presented with a POA signed by an unlicensed forwarder, with no POA from the actual buyer, must decline the filing — accepting it would mean transacting customs business without authority from a party entitled to confer it.

A licensed broker may delegate to another licensed broker as a subagent under 19 CFR 141.43, but only where the underlying power of attorney expressly confers the power of delegation.

Is It Customs Business? The 19 CFR 111.1 Test
Test Your Knowledge

A software company operates a value-added network. Importers key their own completed entry data into the company's portal; the company validates the file format, transmits the data to CBP through ABI, and returns CBP's responses. It never selects a classification, computes an entered value, or corrects substantive data. Is the company transacting customs business?

Test Your Knowledge

A large manufacturer's in-house trade compliance department writes classification policies, trains staff, and audits completed entries for the parent company and its three wholly owned subsidiaries. It does not prepare or file any entry documents; an outside licensed broker does that. The department also begins preparing and filing entry summaries for an unrelated joint-venture supplier as a favor. How does 19 CFR 111.1 treat these two activities?

Test Your Knowledge

An unlicensed freight forwarder that has no financial interest in the goods appears as consignee on an ocean bill of lading. It signs a customs power of attorney purporting to appoint a licensed broker to file the entry and declare value on behalf of the ultimate U.S. buyer, from whom the forwarder holds no power of attorney. How must the broker proceed?
