Hire a customs broker and the problem becomes theirs. That's the assumption, and it's wrong. Under US law the importer of record carries the obligation to declare goods correctly, and nothing shifts it: not a service agreement, not a power of attorney, not fifteen years of flawless service.
So: what it covers, who eats the risk, and what changed in the eighteen months that gave this teeth.
What Is Trade Compliance?
Trade compliance is the set of legal obligations an importer or exporter must meet when moving goods across a border. In the United States it spans five areas: classifying goods correctly, declaring their value correctly, determining country of origin, meeting the requirements of other federal agencies that regulate the product, and keeping records for five years. The importer of record holds this responsibility by law, even when a licensed customs broker files on their behalf.
Duty payment is the output. It isn't the discipline. Before anyone works out what's owed, somebody decides what the product legally is, what it's worth, and where it came from. Those three calls drive the number, and one wrong call poisons the rest.
A related mix-up. A customs broker is a licensed provider who files entries with US Customs and Border Protection. Trade compliance is the duty you hold either way.
That difference only shows itself when something breaks.
The Five Pillars of Trade Compliance
Every US import obligation lands in one of five buckets:
- Classification: assigning the correct tariff code
- Valuation: what the goods are worth, rarely what the invoice says
- Country of origin: where they came from, not where they shipped
- Partner government agency requirements: other regulators with a say
- Recordkeeping: five years of documents, plus the thinking behind them
Money and mistakes concentrate in the first two.
Classification
Not a lookup. A legal determination, and people underestimate it constantly. You're producing a ten-digit Harmonized Tariff Schedule code: six digits standardized internationally, two more setting the US rate line, two statistical.
Getting there means running the General Rules of Interpretation in order:
- GRI 1 settles most goods on the headings and the section and chapter notes, which are binding law, not commentary.
- GRI 2 stretches headings over incomplete, unassembled, and mixed goods.
- GRI 3 breaks ties. Most specific heading wins; failing that, essential character; failing that, whichever heading comes last numerically.
- GRI 4 to 6 cover closest kinship, packing, and the same logic at subheading level.
The sequence is the point. Essential character is where arguments love to jump, and you don't get there until GRI 1 and 2 have failed.
The rhythm we see on a ten-line shipment is consistent. Twenty minutes to classify when the supplier hands over a six-digit code. Forty-five when they hand over nothing. Five to ten minutes to write the entry.
The filing is fast. The deciding is not. And when a code is truly ambiguous, a prior CBP ruling in CROSS is the nearest thing to a definitive answer.
Valuation
The half almost nobody writes about, and by our reading it's where the agency's attention is drifting.
The default basis is transaction value, the price paid or payable when goods are sold for export to the US. Assists, packing costs, and royalties owed as a condition of sale get added on, and related-party sales draw scrutiny because the price may not be arm's length.
Then there's the pattern importers rarely catch on their own. US duties aren't part of the price actually paid or payable, yet companies buying on DDP terms sometimes leave that cost sitting inside the declared value. Duty then gets calculated on a base with duty baked in. They overpay. Every shipment, quietly.
Underpay and you've got enforcement exposure. Overpay and the money is simply gone, because nobody at CBP is going to ring you up about it.
Country of Origin
Origin is a legal conclusion about where a good was made. Not where it sailed from. Goods don't become products of a third country by passing through.
Where a good pulls materials from several countries, the test is substantial transformation: processing must produce a new and different article of commerce with its own name, character, or use. Bolting parts together doesn't clear it.
One distinction matters more than the rest. Preferential origin under a trade agreement is stricter than non-preferential origin, and the two can land differently. A product assembled in Mexico from Chinese parts may be legitimate to mark Mexican while flunking the USMCA rules that would have made it duty-free.
A certificate of origin records that a good met the rule. It is not evidence that it did.
Partner Government Agency Requirements
CBP runs the border, but it isn't the only agency with a say. The FDA, EPA, DOT, USDA, and CPSC each set their own.
What you owe depends on the goods. A textbook needs almost nothing. Cosmetics need FDA registration, a product code, and affirmations of compliance. A vehicle drags in DOT and EPA.
These requirements move under you. CPSC's filing mandate kicked in on 8 July 2026, and certificate of compliance data now goes through ACE at entry rather than sitting in a drawer until asked for. Foreign Trade Zone entries follow in January 2027. Value makes no difference.
Recordkeeping
Five years from the date of entry, in the categories at 19 CFR Part 163.
What operations underestimate isn't holding onto documents. It's holding onto reasoning. If CBP questions a classification three years later, the code alone isn't an answer: you need to reconstruct why that code, on what basis. Most importers keep the answer and lose the working out, and that gap turns a routine inquiry into an expensive one.
Who Is Actually Liable? Reasonable Care Explained
The standard lives at 19 U.S.C. 1484, rewritten by the Customs Modernization Act in 1993. It requires the importer of record to use reasonable care to enter, classify, and value imported goods. CBP then fixes the final classification and value.
Read that split carefully, because it's the whole ballgame. The importer performs. CBP reviews. A broker acts as your agent, and agency doesn't move the duty an inch. Fall short and you face delayed release, sometimes penalties, occasionally criminal referral.
No statute pins it down. In practice it means a documented process and acting on what you know. The failure mode we actually see isn't a hard question answered badly. It's the slow creep of box-checking, where somebody transmits data they have every reason to doubt.
Three mechanisms matter when something's gone wrong:
- CF-28 requests for information. CBP asks about an entry. These are uncommon and usually handled in-house: prove the trade agreement claim, produce the origin certificate, move on.
- Post summary corrections. A PSC fixes an entry summary before liquidation, within 300 days of entry or 15 days before scheduled liquidation, whichever lands first. After that, options narrow to a protest within 180 days under 19 U.S.C. 1514, or a prior disclosure.
- Prior disclosure. Where you end up when a review turns up something systematic. Counsel gets involved. Not cheap.
A routine inquiry costs a few hours. A finding that the same error repeats across years of entries costs far more, and what separates them is usually whether anyone was checking.
What Changed: Trade Compliance in 2026 vs. Five Years Ago
For three decades the direction of travel ran toward fewer barriers. That reversed, and the last eighteen months have been the wildest stretch in modern US trade practice.
The legal basis for broad tariffs got rebuilt twice this year. On 20 February 2026 the Supreme Court held in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act doesn't authorize the president to impose tariffs, wiping out IEEPA tariffs imposed since February 2025. CBP stopped collecting on 24 February. Same day, the administration pivoted to Section 122 of the Trade Act of 1974 and a 10% global surcharge.
Section 122 comes with hard walls: a 15% ceiling, 150 days without congressional extension. The Court of International Trade struck it down on 7 May, but relief reached only the named plaintiffs, so collection carried on until it expired by statute on 24 July 2026.
It was replaced inside the hour. USTR finalized a Section 301 action tied to forced-labor findings, 10% or 12.5% across roughly 60 economies, about 99% of US imports. Separate proclamations on 20 July invoked Section 338 of the Tariff Act of 1930 for the first time in its history, adding 50% on roughly 554 Canadian tariff lines from 19 August.
Duties stack now. One import can sit under an MFN rate, a Section 232 action, a Section 301 action, and antidumping duties at once. Every layer keys off classification and origin, so one error propagates through the lot.
Low-value shipments lost their exemption. De minimis let goods under $800 in duty-free with barely any paperwork. Suspended for China and Hong Kong in May 2025, then globally that August. On 24 June 2026 CBP suspended it indefinitely by regulation, and the One Big Beautiful Bill Act kills it by statute from 1 July 2027.
Regulatory change isn't news you read quarterly anymore. It's a change set you apply against your catalogue, and the interval is weeks.
Where Trade Compliance Programs Actually Break
Three patterns keep surfacing in the programs we look at.
Documents, not filing. The entry takes minutes. The packet takes days, because first-time importers have no idea what their commodity requires until they're late.
Inconsistency beats error as a risk. We've seen the same entry written three different ways inside one operation. A consistent mistake you can live with: find it once, fix it once. Three treatments of identical facts leave nothing to audit against.
Knowledge concentration. At one brokerage, the specialist who handled a product category walked out and nobody left knew how to file those entries. The codes sat in the system. The reasoning didn't.
Frequently Asked Questions
What is trade compliance?
Meeting the legal requirements that govern importing and exporting goods. In the US that means classifying goods correctly, declaring their value correctly, determining country of origin, satisfying other federal agencies that regulate the product, and keeping records for five years.
Who is responsible for trade compliance, the importer or the customs broker?
The importer of record. Under 19 U.S.C. 1484 the importer must use reasonable care to enter, classify, and value imported goods. A broker acts as the importer's agent and can file on their behalf, but the legal obligation does not transfer. If an entry is wrong, CBP looks to the importer.
What is an HTS code?
A ten-digit number identifying a product in the Harmonized Tariff Schedule of the United States. The first six digits are internationally standardized, digits seven and eight form the US rate line that sets duty, and the last two are statistical. You reach it by applying the General Rules of Interpretation in order, not by keyword search.
What changed in trade compliance in 2026?
The Supreme Court struck down IEEPA-based tariffs in February 2026, and the legal basis for broad tariffs was rebuilt twice within six months, ending with a Section 301 forced-labor action covering roughly 60 economies from 24 July. The de minimis exemption for shipments under $800 was indefinitely suspended by regulation in June 2026 and is statutorily eliminated from July 2027.
