Import & Customs Compliance for a Foreign-Owned US LLC (FBA, Shopify, 3PL)

Under the customs regulations an importer can transact customs business on its own account without being a licensed broker; only those who act as a broker for others need a license. So a foreign-owned U.S. LLC can serve as the importer of record (IOR) for its own FBA, Shopify, or 3PL replenishment entries. The customs rules care about who makes the entry and assumes liability, not who ultimately fulfills the customer order.

Registration runs through CBP Form 5106, the record that creates or updates importer identity and assigns a unique importer number in CBP systems. An importer may use an EIN, SSN, or a CBP-assigned number; organizations without an EIN or SSN can request a CBP-assigned number on the form. For a foreign owner with no SSN, the practical path is for the LLC to obtain its own EIN and use that — the owner’s lack of an SSN is not the blocker.

The EIN itself matters on the IRS side too, because a foreign-owned disregarded U.S. LLC needs one to file Form 5472. International applicants who cannot use the online IRS EIN tool apply by phone, fax, or mail (Form SS-4), then complete 5106. The answer is rarely “you cannot import” — it is “use the non-online EIN routes, then register.”

Frame the broker correctly. A customs broker prepares and files entries, coordinates with the surety, and handles CBP operationally — but a broker is not a liability shield. The importer still owns classification, value, origin, and duty exposure. Many foreign founders wrongly assume Amazon or the forwarder “is the importer”; usually it is not, unless the paperwork is explicitly structured that way.

CBP requires a basic importation and entry bond, and recognizes both single-entry and continuous forms under 19 CFR Part 113. The two are sized differently.

A single-entry bond is generally at least the entered value plus duties, taxes, and fees for that one shipment. It fits a one-container test import or a small pilot launch, but you buy a new bond for every entry.

A continuous bond is usually 10% of the duties, taxes, and fees paid over a rolling 12-month period, subject to a $50,000 minimum. For recurring FBA or 3PL inbound replenishment it is the cleaner operating default: it covers a year of entries, supports multiple ports and brokers, and avoids re-bonding every shipment.

For an e-commerce seller doing repeat replenishment, the continuous bond is almost always the right fit; reserve the single-entry bond for genuine one-offs.

As of June 2026, the tariff picture is materially different from 2025, and it is volatile — verify the live HTS before filing. The clean way to read it is four separate buckets: ordinary HTSUS column-1 duty; Section 301 duties on China-origin goods; the now-ended 2025 IEEPA tariffs; and the temporary section 122 surcharge that took effect in February 2026.

Layer 1 — ordinary duty. Every SKU has a column-1 HTSUS rate driven by its classification. This is the baseline before any trade-action layer.

Layer 2 — Section 301 (China), STILL ALIVE. Section 301 duties on products of China remain in force, administered through the Chapter 99 / 9903.88 series and the HTSUS legal notes. The right mid-2026 question is not “did China tariffs disappear” but “which HTS line and which Chapter 99 line apply to this SKU, and is any exclusion still active?”

Layer 3 — 2025 IEEPA tariffs, ENDED Feb 20, 2026. A February 20, 2026 order ended the 2025 IEEPA ad valorem duty actions (they “shall no longer be in effect” and “shall no longer be collected”), and CBP is processing IEEPA duty refunds. The same order expressly did not touch Section 232 or Section 301. If the importer paid 2025 IEEPA duties, it should evaluate refund eligibility.

Layer 4 — temporary § 122 surcharge. On February 20, 2026 the President imposed a temporary 10% import surcharge under section 122 of the Trade Act of 1974, effective February 24, 2026, for 150 days, subject to listed exclusions. So a China-origin SKU may now face ordinary duty plus any Section 301 line plus the § 122 surcharge, unless an exclusion applies. The § 122 surcharge can change after ~July 2026 if it is extended, modified, or replaced — re-check before relying on it.

The old playbook — ship each customer order under $800 and clear it duty-free under the 19 U.S.C. § 1321 de minimis — no longer works. It ended in stages.

First, duty-free de minimis treatment ceased for covered PRC and Hong Kong products entered from May 2, 2025 onward; non-postal shipments of $800 or less now require an appropriate entry type in ACE, and postal shipments fell under special carrier-collected duty methods.

Then the suspension widened to all countries through the July 30, 2025 order and a February 20, 2026 continuation, which kept the de minimis suspension in place and directs CBP to collect duties on international postal shipments using the temporary import-surcharge methodology. The § 122 surcharge applies to low-value shipments, including goods entering through the postal system.

The practical consequence is blunt: a foreign-owned U.S. LLC cannot build its U.S. retail model on de minimis. Bulk import plus domestic fulfillment through FBA or a 3PL is now the legally stable design.

The HTSUS is legal text, not a convenience label. Its General Rules of Interpretation (GRIs), Additional U.S. Rules, and General Notes govern classification, starting with GRI 1. “Home decor,” “pet accessory,” or “kitchen organizer” is never enough for a defensible FBA or Shopify file — you need composition, function, construction, and use.

For ambiguous or repeat SKUs, get a binding ruling early. Under 19 CFR Part 177, a CBP ruling letter applies customs law to specific facts and is binding on CBP until modified or revoked, as long as the real merchandise matches the ruling’s facts. For a repeat SKU catalog, rulings turn a fragile customs program into a scalable one.

Country of origin is separate from the shipping route, the invoice issuer, or the exporter’s address. The marking rules in 19 CFR Part 134 require every foreign article to be marked with its origin unless an exception applies, and non-preferential origin turns on substantial transformation: does the third-country processing produce a new name, character, or use, with assembly that is genuinely complex and meaningful rather than minimal?

Routing China-origin goods through Vietnam, Hong Kong, or the EU does NOT change origin by itself. CBP rulings hold that repacking, relabeling, simple kitting, and simple assembly do not substantially transform the goods — a China product shipped via a third country is still a China product for Section 301 and marking purposes. Origin changes only when the third-country manufacturing genuinely transforms the merchandise; light assembly or routing alone never does.

Valuation starts with transaction value under 19 U.S.C. § 1401a and 19 CFR 152.103 — the price actually paid or payable for the goods when sold for export to the U.S., plus required additions: packing, buyer-paid selling commissions, assists, certain royalties and license fees, and proceeds that accrue to the seller. Post-import rebates are disregarded for customs transaction value.

Assists are routinely missed by digital brands. If the U.S. buyer provides molds, tooling, dies, engineering, artwork, or components to the foreign factory at no charge or below market, CBP may require an addition to transaction value. This is common in private-label Amazon sourcing where the brand funds tooling or packaging but the customs file values only the factory invoice.

Related-party pricing draws extra scrutiny. Transaction value between related parties can be accepted only if the relationship did not influence the price or the price closely approximates a statutory test value; when CBP has doubts the importer must show detailed circumstances of sale. Transfer-pricing paperwork is relevant but is not a substitute for customs-specific proof.

IRC § 1059A is the bridge. For related-party imports, the costs taken into account in computing basis or inventory cost cannot exceed the same costs used in computing customs value — with limited upward adjustments for items tax capitalizes but customs may not, like freight and insurance. A final CBP determination binds the taxpayer for § 1059A. The classic trap is transfer pricing, year-end true-ups, or post-import accounting moving tax cost away from customs cost with no one checking § 1059A.

IRC § 263A then capitalizes duties into inventory. Customs duties on goods still on hand do not vanish into period expense — they are part of inventory cost and move into COGS as the inventory is sold. This is why the linked transfer-pricing analysis and this customs valuation have to be designed as one model, not separate silos — see the related-reading note below; this guide extends that discussion to the customs side rather than duplicating it.

CBP audits importers, including e-commerce importers, often by referral and through the Focused Assessment program — a comprehensive, risk-based test of internal controls and compliance. Audits target the same issues that make or break an FBA or 3PL program: classification, value, origin, admissibility, recordkeeping, and whether controls hold up when shipments scale.

The main civil penalty statute is 19 U.S.C. § 1592, which prohibits entry by material false statement, material omission, or act that is fraudulent, grossly negligent, or negligent. The tiers escalate sharply: negligence up to the lesser of domestic value or two times lost duties (or 20% of dutiable value if there is no revenue loss); gross negligence up to the lesser of domestic value or four times lost duties (or 40% if no revenue loss); fraud up to the domestic value of the merchandise.

Prior disclosure is the cure. Under 19 CFR 162.73, a valid prior disclosure — made before, or without knowledge of, the start of a formal investigation — cuts the maximum penalty for negligent and grossly negligent violations to interest on the lost duties, and for fraud to one times the lost duties (or 10% of dutiable value if no revenue loss). Sophisticated importers disclose early rather than trying to quietly fix it on the next entry.

The records set is the defense. A workable file includes the executed 5106 record, EIN letter, customs bond, broker power of attorney, HTS classification memos and any Part 177 rulings, country-of-origin analysis and factory flowcharts, commercial invoices and POs, assist schedules, entry summaries and duty payment records, landed-cost journal entries, and a year-end reconciliation from customs values to book inventory and to Form 5472 support. Related-party purchases on the books and on Form 5472 must tie to the entry summaries — if they do not reconcile, the company is building an audit problem.
