If you bring goods into the United States, 19 USC 1484 makes you, as the importer of record, legally responsible for filing accurate entry paperwork with U.S. Customs and Border Protection, correctly classifying and valuing your merchandise, paying every applicable duty and fee, and keeping the records to prove it. The statute wraps all of that in a single operating requirement: reasonable care. Fall short and you face civil penalties that scale with fault, potential criminal prosecution for fraud, and the loss of your right to challenge CBP’s assessment if you miss a deadline.1Office of the Law Revision Counsel. 19 USC 1484 Entry of Merchandise
Who Qualifies as the Importer of Record
The statute is specific about who can serve in this role. The importer of record must be the owner or purchaser of the merchandise, or a licensed customs broker designated by the owner, purchaser, or consignee.1Office of the Law Revision Counsel. 19 USC 1484 Entry of Merchandise The party can be an individual, a corporation, or another business entity, but at least one party involved in the entry must be a U.S. resident capable of accepting service of process.
Taking on this role means you own the compliance outcome for the shipment. You’re accountable for the accuracy of every figure on the entry, whether you typed it yourself or a freight forwarder handled the filing. You’re also responsible for making sure the goods satisfy other federal agencies’ requirements. Food products have to meet FDA rules; certain electronics need FCC authorization. CBP can refuse entry for those failures no matter how carefully you calculated the duties.
Most importers work through the Automated Commercial Environment, CBP’s electronic filing portal. ACE lets account holders file entries, pay duties, run reports to spot errors across their entries, respond to CBP inquiries, and track antidumping or countervailing duty cases.2U.S. Customs and Border Protection. How to Use the Automated Commercial Environment (ACE)
What Reasonable Care Actually Requires
“Reasonable care” appears at the top of 19 USC 1484 and governs every obligation that follows. It’s not a vague aspiration. CBP treats it as a measurable legal standard, and it’s the yardstick the agency uses when deciding whether an error was innocent or negligent.
In practice, reasonable care means you took affirmative steps to get things right before the goods arrived. For classification, that might mean researching prior CBP rulings for similar products, consulting the Harmonized Tariff Schedule, or hiring a specialist. For valuation, it means understanding whether your purchase price includes all required additions like royalties or assists, and documenting the basis for your declared value. For recordkeeping, it means organized files that can be produced quickly on request.
CBP has published an “Informed Compliance” checklist that walks importers through the questions they should be asking about classification, valuation, and marking before each entry. Working through it and documenting your answers is one of the strongest ways to show compliance if your entries are questioned later.
Filing the Entry: Two Steps, Not One
Importing involves two rounds of filings. First, you submit entry documentation so CBP can decide whether to release the goods. Then you complete the entry by filing the entry summary, which gives CBP the full detail needed to assess duties.
The entry summary, filed on CBP Form 7501, must be submitted with estimated duties within 10 working days after the time of entry if it wasn’t filed at release.3eCFR. 19 CFR 142.12 Time for Filing or Submission for Preliminary Review The form declares value, tariff classification, duty rate, and country of origin for each line of merchandise. Most penalty exposure begins here, so this is where your reasonable care work pays off.
Supporting documents include the commercial invoice, which details the goods, quantities, and prices and is the primary basis for CBP’s valuation review. If the invoice price looks off, CBP may request purchase orders, wire transfer records, or contracts. A packing list itemizes the shipment. For ocean freight, the bill of lading acts as the contract of carriage and confirms your right to take possession; for air freight, the air waybill does the same job.
Goods claiming reduced duties under a trade agreement need a certification of origin. The USMCA doesn’t require a specific form; it uses nine required data elements that can appear on an invoice or any other document.4U.S. Customs and Border Protection. USMCA Frequently Asked Questions Without a valid certification, CBP denies the preferential rate and applies the standard column 1 rate.
Two boundary points worth flagging. First, wood packaging like pallets, crates, and dunnage must be heat-treated or fumigated and bear an ISPM 15 mark, or CBP will not admit the shipment.5Animal and Plant Health Inspection Service (APHIS). Import ISPM 15-Compliant Wood Packaging Material into the United States Second, the $800 de minimis exemption under Section 321 has been suspended. As of 2026, the suspension applies to shipments from all countries regardless of value or mode, and non-postal shipments must be filed using a standard entry type in ACE by a qualified party.6The White House. Continuing the Suspension of Duty-Free De Minimis Treatment for All Countries Bona fide gifts valued at $100 or less (or $200 from certain U.S. territories) remain exempt, but nearly all commercial imports now require a formal or informal entry.
Classifying Your Goods
Every imported product gets a 10-digit code under the Harmonized Tariff Schedule of the United States. The first eight digits set the legally binding tariff subheading and duty rate; the last two are a statistical suffix.7United States International Trade Commission. Frequently Asked Questions about Tariff Classification, the Harmonized Tariff Schedule, Importing, and Exporting Because duty rates vary sharply between categories, misclassification is one of the fastest ways to trigger a penalty. CBP, not the importer, makes the final determination on the correct rate.8U.S. Customs and Border Protection. Determining Duty Rates
Classification follows the General Rules of Interpretation built into the tariff schedule. Most products fall neatly into a heading based on material and function. Composite goods or products that straddle multiple headings need more analysis, and that’s where disputes usually start.
If you’re unsure before importing, request a binding ruling from CBP. The request goes to CBP’s National Commodity Specialist Division and must describe the merchandise in enough detail for a classification determination.9eCFR. 19 CFR 177.2 Submission of Ruling Requests Once issued, a binding ruling gives you legal certainty on classification and duty rate before goods ship. The Customs Rulings Online Search System (CROSS) database lets you see how similar products have been classified in the past.
Valuing Your Goods
The value you declare determines what you owe, so CBP scrutinizes it. The default method is transaction value: the price actually paid or payable for the goods when sold for export to the United States. That price isn’t just the invoice amount. It must also include additions like packing costs, selling commissions paid by the buyer, royalty or license fees tied to the imported goods, and any assists (materials or services the buyer provides to the seller for free or at reduced cost).
Transaction value only works when specific conditions are met. There can’t be restrictions on how the buyer uses or resells the goods (other than those imposed by law or geography), the sale can’t depend on conditions whose value can’t be determined, and no part of the resale proceeds can flow back to the seller unless an adjustment can be made.10eCFR. 19 CFR Part 152 Classification and Appraisement of Merchandise
Related-party sales get closer review. CBP doesn’t automatically reject the transaction value, but it applies two tests. First, it examines the circumstances of the sale for evidence that the relationship didn’t influence the price, such as the parties dealing at arm’s length, industry-standard pricing, or a price covering all costs plus the seller’s typical profit margin. Second, CBP may compare the declared value against test values based on identical or similar merchandise sold to unrelated U.S. buyers.
When transaction value can’t be used at all, CBP applies a hierarchy: transaction value of identical merchandise, transaction value of similar merchandise, deductive value (working backward from the U.S. resale price), computed value (building up from production costs), and a fallback method. Each has its own documentation demands, and inconsistent practices across entries reliably attract audits.
Antidumping and Countervailing Duties
Beyond regular tariff duties, some goods carry antidumping duties (for foreign sales below fair market value) or countervailing duties (to offset foreign government subsidies). You’re responsible for checking whether your goods fall under an active AD/CVD order before they arrive. When an order applies, you deposit estimated duties at entry, and if no administrative review is requested, duties are assessed at the cash deposit rate that applied when the merchandise entered.11eCFR. 19 CFR Part 351 Antidumping and Countervailing Duties A false certification, or failing to certify at all when required, can result in suspended liquidation and duty assessment at the highest applicable rate.
Keeping the Records
You must keep all records related to an import entry for five years from the date of entry. Records not tied to a specific entry follow the same five-year period, measured from the date of the activity that required creating them. Records include invoices, entry summaries, correspondence with CBP, contracts, and payment documentation. Failing to maintain them can bring penalties, heightened scrutiny on future entries, or suspension of import privileges.
Electronic recordkeeping is allowed, but you must notify CBP’s Regulatory Audit office in Charlotte, North Carolina, at least 30 calendar days before switching to an alternative storage method. Acceptable formats include machine-readable data, optical media, and microfiche, provided your system preserves the integrity and readability of the originals and allows retrieval within a reasonable time after a CBP request.12eCFR. 19 CFR Part 163 Recordkeeping
A few practical points trip up importers moving to digital. You must keep original-format entry records (except packing lists) for at least 120 calendar days after the release period ends. Your system needs an effective labeling and indexing process, written operational procedures, and annual internal testing. You maintain both a working copy and a backup in a secure location, and you bear the cost of producing hard copies when CBP asks.
Liquidation and the 180-Day Protest Window
After you file an entry, CBP reviews it and eventually “liquidates” it, meaning it makes its final computation of the duties owed. If CBP doesn’t liquidate within one year from the date of entry, the entry is deemed liquidated at the duty rate, value, and quantity you declared.13Office of the Law Revision Counsel. 19 USC 1504 Limitation on Liquidation CBP can extend that window, and events like court orders or pending investigations can suspend it.
If you disagree with CBP’s liquidation, you have the right to file a protest. Protests can challenge the appraised value, the classification and duty rate, exclusion of merchandise, the liquidation itself, or a denied drawback claim.14Office of the Law Revision Counsel. 19 USC 1514 Protest Against Decisions of Customs Service The deadline is 180 days after the date of liquidation. Miss it and the liquidation becomes final and conclusive against everyone, including you. If CBP denies the protest, the next step is a civil action in the U.S. Court of International Trade. This is one of those deadlines where a day late means losing the right entirely.
What Errors Cost You
Under 19 USC 1592, importers face civil penalties for any material false statement or omission in entry documentation, whether or not the government actually lost revenue. Penalties scale with culpability:
- Negligence: up to two times the lost duties, taxes, and fees, or if the violation didn’t affect the duty assessment, up to 20 percent of the dutiable value.15Office of the Law Revision Counsel. 19 USC 1592 Penalties for Fraud, Gross Negligence, and Negligence
- Gross negligence: up to four times the lost duties, or if duties weren’t affected, up to 40 percent of the dutiable value.
- Fraud: up to the full domestic value of the merchandise. CBP may also seek forfeiture of the goods.
In every tier, the penalty is capped at the lesser of the calculated amount or the domestic value of the merchandise. Importers are strictly liable for the accuracy of their entries, meaning “my broker handled it” is not a defense.
Fraud can also trigger criminal prosecution under 18 USC 542, which covers entering goods through false statements. Conviction carries a fine and up to two years of imprisonment.16Office of the Law Revision Counsel. 18 USC 542 Entry of Goods by Means of False Statements Criminal referrals are uncommon for ordinary errors, but deliberate schemes to evade duties or trade restrictions do get prosecuted.
Fixing a Past Error Before CBP Finds It
If you discover a problem in a past entry, disclosing it to CBP voluntarily before an investigation starts dramatically reduces your exposure. A valid prior disclosure under 19 USC 1592(c)(4) caps the penalty:
- Fraud with prior disclosure: penalty capped at 100 percent of the unpaid duties, taxes, and fees if you tender the unpaid amount at disclosure or within 30 days of CBP’s calculation. If the violation didn’t affect duty assessment, the cap is 10 percent of the dutiable value.
- Negligence or gross negligence with prior disclosure: penalty limited to interest on the unpaid duties, calculated at the IRS underpayment rate from the date of liquidation, provided you tender the shortfall.
Timing is what makes or breaks the disclosure. It must happen before you know about the start of a formal CBP investigation, and you bear the burden of proving that lack of knowledge. The disclosure itself must identify the merchandise, the entry numbers or approximate dates and ports of entry, and explain what went wrong and what the correct information should have been. If you don’t have every detail immediately, you have 30 days from the initial disclosure to supply them.17eCFR. 19 CFR 162.74 Prior Disclosure Mark the envelope “prior disclosure” and deliver it to the CBP port of the violation. Certified or registered mail with return receipt fixes the disclosure date at the time of mailing, which matters if you’re racing the clock.
Working with a Customs Broker
Licensed customs brokers handle the mechanics of filing entries, calculating duties, and navigating regulatory requirements for most importers. Under 19 USC 1641, anyone conducting customs business on behalf of another person must hold a valid broker’s license, earned by passing a CBP-administered exam.18Office of the Law Revision Counsel. 19 USC 1641 Customs Brokers Only U.S. citizens are eligible for an individual broker’s license.19eCFR. 19 CFR Part 111 Customs Brokers
Before a broker can act for you, execute a customs power of attorney. It can be filed on CBP Form 5291 or in any format that includes the required elements: names and legal designations of principal and agent, the principal’s state of organization, a grant of authority, the principal’s signature, and either an expiration date or a statement that the power continues until revoked in writing. Partnerships must limit their powers of attorney to two years. Unless the power of attorney specifically authorizes the broker to act at all CBP ports, it must list each port or Center where the broker is authorized to act.20eCFR. 19 CFR Part 141 Subpart C Powers of Attorney
Hiring a broker does not shift your legal responsibility. You remain the importer of record, and every penalty, audit, and investigation flows back to you. A good broker reduces risk by catching errors before they become violations; a bad one creates exposure you didn’t know existed. Verify the license, check the broker’s history with CBP, and make sure they have experience with your specific type of merchandise.
