If you operate a US-China business arrangement, the legal architecture set up at the outset usually determines what your exposure looks like later. We've covered the architecture side in several articles: Building a US Brand for a Chinese Manufacturer addresses joint ventures between US-side partners and Chinese manufacturers; US Subsidiary of Chinese Company covers Chinese-parent-owned US subsidiaries; and Structuring US-China Business Ventures walks through the patterns we've observed across cross-border deals.
This article addresses the other side of that conversation: what happens when the structuring is incomplete, when it's missing entirely, or when the documentation hasn't kept up with the reality of the business. The exposure is not theoretical, the numbers are not small, and the corporate form does not always protect the people who run the business.
The discussion below applies across the common US-China fact patterns. Some readers will be in a co-owned joint venture. Some will be running a Chinese-controlled US subsidiary. Some will be the US-side owner of an import operation supplied by a related Chinese factory. The specific penalty exposure varies with the structure, but the underlying regulatory framework is consistent.
Why US-China Business Ventures Draw Heightened Scrutiny
US customs law treats parties as "related persons" when they fit any of the categories under 19 USC 1401a(g). The list includes members of the same family (spouse, parents, siblings, children, ancestors, lineal descendants), entities under common control, and anyone holding 5% or more of the voting stock of the organization on the other side. The IRS uses a broader concept under Section 482, which reaches commonly controlled organizations more generally.
These rules apply to the standard US-China business fact patterns. A joint venture co-owned by a Chinese manufacturer and a US-side partner is a related-party arrangement. A US subsidiary owned by a Chinese parent is a related-party arrangement. A US-side importer buying from a family-owned Chinese factory is a related-party arrangement. The specific facts of each structure vary, but the related-party treatment is shared.
The legal effect of related-party status is that regulators are entitled to scrutinize transactions more closely, declared values can be challenged more easily, and the burden of proof on key questions often shifts to the taxpayer. The practical effect is that arrangements which seem informally functional often turn out to be missing the documentation an audit assumes you have.
CBP Customs Penalties
The primary customs penalty statute is 19 USC 1592, which applies when goods enter the United States by means of false statements or omissions of material fact. The statute creates three tiers of culpability:
Negligence: the maximum penalty is the lesser of the domestic value of the merchandise or two times the unpaid duties, taxes, and fees. If no duty was lost, the maximum is 20% of the dutiable value.
Gross negligence: the maximum penalty is the lesser of the domestic value or four times the unpaid duties, or 40% of the dutiable value where no duty was lost.
Fraud: the maximum penalty is the full domestic value of the merchandise.
Two features of this regime matter most for US-China business ventures. First, the look-back period under 19 USC 1621 generally runs five years from the date of the alleged violation for negligence and gross negligence cases, and five years from the date of discovery of fraud for fraud cases. CBP can therefore reach back through several years of entries in a single action.
Second, the penalty is calculated on the entries, not on a single transaction. For an importer bringing in $2 million of goods per year, a gross negligence finding spanning five years can produce penalty exposure in the seven figures, plus the unpaid duties and interest. Penalties of this scale are not unusual in cases where the importer lacks documentation supporting the declared values.
The kinds of patterns that produce these results include undocumented price adjustments between related parties, retroactive changes communicated informally but never reflected in formal invoicing, mismatches between the price on the invoice and the amount actually wired, transfer pricing that was set with tax considerations in mind but not coordinated with customs valuation, and the omission of side payments (gifts, family support, "loans" that are not repaid, services provided in lieu of payment) that effectively reduce or augment the price paid for the goods.
A feature of 19 USC 1592 worth flagging: the statute reaches more than the corporate importer of record. CBP can pursue officers, employees, agents, and consignees who participated in or aided the entry. The corporate form does not fully shield the individuals who signed the entries or directed the documentation.
IRS Tax Penalties
The IRS focuses on the same prices from a different angle. Under Section 482, the IRS has the authority to reallocate income between related parties when the prices between them do not reflect what unrelated parties would have agreed to. For US-China arrangements, the typical concern is that the US side is paying too much for imported goods or services, which reduces US taxable income and shifts margin to the offshore related entity.
When the IRS reallocates income under Section 482, the result is back taxes plus interest. Penalties under Section 6662 may also apply. The 20% accuracy-related penalty under Section 6662(e) generally applies in cases of substantial valuation misstatement, increased to 40% under Section 6662(h) for gross valuation misstatement. The specific thresholds depend on the size of the adjustment relative to your gross receipts and other factors. Smaller adjustments may still draw a general 20% accuracy-related penalty under other provisions of Section 6662.
Two information returns can also carry meaningful penalties:
Form 5472 is filed by US corporations that are at least 25% foreign-owned, and by foreign-owned US disregarded entities. The penalty under IRC Section 6038A is $25,000 per form per year for failure to file or filing a substantially incomplete return. If the failure continues for more than 90 days after the IRS notifies the reporting corporation, an additional $25,000 applies for each 30-day period the failure continues. There is no statutory cap.
Form 5471 may apply where you or your US business owns 10% or more of a Chinese (or other foreign) corporation. The base penalty under IRC Section 6038(b) is $10,000 per form per year, with continuation penalties subject to a $50,000 cap, plus potential reductions to allowable foreign tax credits.
Whether either form applies depends on the specific ownership structure. Different US-China arrangements trigger different reporting obligations. A Chinese-parent-owned US sub typically triggers Form 5472. A US-side owner with significant equity in a Chinese factory typically triggers Form 5471. A US-side importer buying from a family-owned Chinese factory in which they hold no equity typically triggers neither.
Personal Liability
This is the area most operators in US-China arrangements underestimate. The LLC or corporation can shield individuals from many general business creditors and claims, but it does not insulate them from key customs and tax exposures.
On the customs side, 19 USC 1592 expressly reaches officers, employees, agents, and others who participated in or aided the entry, not only the corporate importer of record. CBP can pursue these individuals personally for the same penalty exposure described above. The US-side partner in a joint venture, the operating officer of a Chinese-owned US sub, and the owner-operator of a US import business all carry direct exposure under this statute if they participated in the entries at issue.
On the tax side, the corporation generally bears the income tax liability. Criminal exposure in serious cases reaches individuals. IRC Sections 7201 (tax evasion), 7203 (willful failure to file or pay), and 7206 (false statement on a return) each carry potential imprisonment and significant fines. Customs-side criminal exposure includes 18 USC 542 (entry of goods by false statements) and 18 USC 545 (smuggling) in extreme cases. Criminal prosecution of small operators is uncommon, but it is not unheard of, and it tends to follow patterns of conduct rather than isolated errors.
The practical reality for owner-operators and operating partners in US-China ventures is that the same person typically signs the customs entries, signs the corporate tax return, and runs operations. That person carries all three exposure points simultaneously.
How CBP and the IRS Actually Find These Violations
The most common assumption is that compliance issues only become problems if there is a major audit operation. That is not generally how these matters surface. The more typical paths to discovery include:
A CF-28 Request for Information. CBP routinely sends these in connection with specific entries. The request asks for supporting documentation. The response is a sworn submission, and inconsistencies between what is provided and what CBP later finds elsewhere become the basis for further action.
A focused assessment or post-entry audit. CBP audits importers based on risk factors, including the presence of related-party transactions, prior questions on entries, and industry trends. Related-party imports tend to be flagged for higher scrutiny.
A whistleblower or third-party complaint. Business disputes, disgruntled former employees, ex-spouses, and former partners can all become sources of information for both CBP and the IRS. The IRS Whistleblower Program under IRC Section 7623 provides financial rewards for actionable tips on significant tax violations, including some related-party pricing matters.
Information sharing between agencies. CBP and the IRS share information through established channels. An IRS audit that finds an unusual transfer-pricing pattern can lead to a CBP inquiry, and the reverse can also happen. Documents prepared for one agency (transfer pricing studies, customs entries, corporate tax returns, intercompany invoices) can be requested or subpoenaed by the other.
Broker concerns. Customs brokers who become uncomfortable with what they are being asked to declare may, in some circumstances, raise questions formally or informally. Brokers also have their own compliance obligations.
The point is not that any of these paths is highly probable in a given year. The point is that the discovery mechanisms are not abstract or unlikely. They occur in ordinary practice, and they tend to surface accumulated issues across multiple years rather than isolated mistakes.
What You Tell One Agency Can Be Used by Another
The risk areas are connected in ways that US-China arrangements particularly invite.
The most common trap is inconsistency. A US importer declares a low transaction value to CBP to minimize duties, then claims a higher cost basis on the federal tax return to reduce taxable income. The reverse also happens: a high transfer price set to lower US taxable income paired with a lower customs value to reduce duties. Both patterns leave a paper trail that a sophisticated examiner can find.
A second trap involves transfer pricing studies prepared for IRS purposes. A study that sets a price at the upper end of an arm's length range, which helps the IRS position, can be used by CBP as evidence that a lower customs value is unsupportable. The reverse trap, where a study supporting a low cost basis is used by the IRS against a high deduction, also exists.
Documents prepared for one regulator can be requested or subpoenaed by another. Intercompany communications (WeChat threads, email correspondence between US-side and Chinese-side principals, informal invoicing) can be discoverable. Consistency across regimes is not optional. The documentation you create for one purpose should be drafted with awareness that another agency may eventually see it.
What to Do If You Think You Have Exposure
A few high-level pointers, not a complete approach:
Do not respond to CBP correspondence (CF-28, CF-29, or audit notice) without first consulting counsel familiar with customs practice. Statements made in response to these requests can be used in subsequent enforcement actions.
For past errors on the customs side, CBP's prior disclosure process under 19 USC 1592(c)(4) allows importers who voluntarily report violations before CBP discovers them to substantially reduce penalty exposure, though unpaid duties and interest still apply.
For past errors on the tax side, amended returns and IRS voluntary disclosure procedures may be available. Whether these are appropriate depends on the facts and the stage of any pending review.
Decisions about whether and how to make disclosures are usually better made with counsel before any disclosure is filed, because once a disclosure is made, the options narrow.
Frequently Asked Questions
We're in a joint venture with a Chinese manufacturer. Are we exposed?
Yes, if the related-party documentation is not in place. Joint ventures between US-side partners and Chinese manufacturers are textbook related-party arrangements under both CBP and IRS rules. The supply pricing between the manufacturer and the US joint venture entity is subject to Section 482 scrutiny and to CBP customs valuation rules. Without documented arm's length pricing, intercompany agreements, and clean records of intercompany transactions, the exposure profile is essentially the same as for any other related-party importer. The fact that the parties are co-owners of the same business does not reduce the exposure; in some circumstances it can increase it because both sides have visibility into the same documents.
We've been operating with informal documentation for years. Is it too late to fix things?
It depends on the facts, but proactive correction is often available. CBP has a "prior disclosure" process under 19 USC 1592(c)(4) under which an importer who voluntarily reports past errors before CBP discovers them can substantially reduce penalty exposure (though unpaid duties and interest still apply). On the tax side, amended returns and voluntary disclosure procedures may also be available. Whether any of these makes sense involves judgment calls best discussed with counsel before any disclosure is filed.
We use an LLC. Can I personally be on the hook?
Yes, in specific circumstances. 19 USC 1592 expressly reaches officers, employees, and agents who participated in or aided the entry, not only the corporate importer. Tax-side criminal exposure under IRC Sections 7201, 7203, and 7206 also reaches individuals. The LLC provides protection against many general business creditors and claims, but it does not insulate the people who signed the entries or directed the documentation from these specific exposures.
We just got a CF-28 from CBP. What now?
A CF-28 is CBP's standard request for information on a specific entry. It is not yet a penalty notice, but how you respond shapes everything that follows. The response is a sworn submission, and statements made in it can be used in subsequent enforcement actions. The standard approach is to consult counsel familiar with customs practice before responding, to assess what is being asked, what is being implied, and what disclosures may be appropriate to make voluntarily.
Could I really go to jail for this?
Criminal prosecution of small operators is uncommon, but it is not unheard of. Federal criminal exposure exists under 18 USC 542 (entry of goods by false statements), 18 USC 545 (smuggling), and IRC Sections 7201, 7203, and 7206 for serious tax violations. Prosecution generally follows patterns of conduct over time rather than isolated errors, and willfulness or fraud is typically required for criminal liability. The civil penalty exposure under 19 USC 1592 and Section 6662 is, in practice, the more common outcome for operators with compliance gaps.
