First-time importers lose money at customs in one predictable way: not from wrong rates, but from registrations started too late. The duty math pen runs on paper; the registration layer runs on calendar — EORI "free but days", bonds "same day if ordered before sailing", IOSS "an intermediary contract". This page is that layer: who you legally are at import, the one-time IDs behind three destination rulebooks, and the filing order that keeps your first container moving through instead of parking.
Importer of Record: Who Signs the Declaration
The Importer of Record (IOR) is the legal entity customs holds responsible for the declaration — classification, valuation, duty payment. It appears on the broker's entry, the bond, and any penalty notice. Your choices, in the order buyers actually evolve:
| IOR form | Setup | Best for | Watch for |
|---|---|---|---|
| Individual (sole proprietor) | Your own name + destination tax ID; USS sole props can register free with CBP | First orders, samples, side-business validation | Customs liability is personal; reselling through marketplaces needs care |
| Your LLC / Ltd | Entity records + EIN/URI + bond in entity name | Anything recurring — separates liability, builds importer history | Annual report fees; banking friction unless registered address is tidy |
| Foreign importer service | A service company signs as IOR in a jurisdiction where you have none | Sellers testing new destinations; genuinely borderless structures | Their compliance culture becomes yours — misdeclaration lands on the service's record; wrong ones keep the risk alive |
| "Supplier's forwarder as IOR" | The origin-side agent clears in your country | Almost never — DDP-flavored comfort | You lose declaration control and NCAA-quality paper trail; DDP trap economics |
The discipline: whichever IOR name you pick, it must match the bond, the PI documents, the payment account and the marketplace seller identity. Mismatches between entity names creates the delayed-release pile that brokers quote urgency fees from — four names that don't match is a customs puzzle no one works gratis.
US: The Customs Bond You Cannot Skip
Every formal US entry requires a customs bond — a surety company's guarantee to CBP that duties/fees/penalties will be paid. Two types matter:
- Continuous bond: annual, covers all your entries including ISF filings and quota. Coverage minimum $50,000, priced at roughly 10% of your expected annual duties/fees — real-world premium $250-450/year for small importers sizing correctly. Requirement: if you'll exceed a handful of formal entries a year, this is the instrument.
- Single-transaction bond (STB): per-shipment, priced $40-70 at typical values, scaled to shipment duty exposure. Sensible for one container a year or trialing a lane.
The crossover math: an STB costs $40-70 per formal entry; the continuous bond runs $250-450 all year. Past roughly 5-6 formal entries annually, continuous wins — and it also covers ISF inconsistencies (which STB holders pay penalty risk for), and customs requires continuous bonds for some entry types (unlabeled goods, certain quota classes). Buy from a surety or through your broker; beware brokers reselling bonds with padded premiums — the $250-450 band is the honest one.
Where informal entry lives: shipments under $2,500 generally clear informally (no bond) — samples, test lots. But ocean freight formally entered always needs ISF (filed 24h before loading at origin), and ISF on an unbonded importer is a mess your forwarder will not love you for.
EU/UK: EORI, IOSS and the PVA Election
- EORI (EU & GB): the customs identification number pinned to your entity. Free. GB typically issues in 1-3 working days; EU member-state variants same-day to 7. File the week you open the PI — the broker's entry references it, and low-value parcel channels (courier express clearances) also want it visible on labels.
- IOSS (EU, parcels under €150): if you sell direct-to-consumer under the low-value regime, VAT must be collected at checkout and remitted monthly through an EU-based intermediary. Non-EU sellers can't register directly — the intermediary (€300-500/year + per-return fees) fronts the registration. Without IOSS, every EU parcel gets customs-collected VAT + courier disbursement fees at the door — the conversion-killer pattern e-commerce buyers report constantly.
- PVA (UK postponed VAT accounting): elect on entry to pay import VAT via your VAT return instead of at the border — cash-flow positive, free, one checkbox + your VRN on the declaration. Repeatedly forgotten by first-time UK importers who pre-pay VAT they could have deferred.
- EU consignee transitions to watch: marketplaces handle some of this for FBA sellers; direct-ship sellers carry it themselves. The documents checklist table row for EU/GB references each of these — this section is the 注册层 behind that row.
The Week-One Registration Calendar
Everything above orders itself into one week of light work — file in this sequence when the PI opens:
- Day 1-2: destination decision confirmed → file the free-but-slow IDs (EORI EU/GB form; CBP ACE importer account for US; IRS EIN if entity needs one). All free.
- Day 2-3: quote the continuous bond from two sureties (or an STB for a one-off) — the broker will offer; compare. Simple tool: expected annual duty dollars ÷ 10 ≈ bond coverage requirement.
- Day 3-4: IOSS intermediary quotes if EU B2C under €150 (a half-day of email — intermediaries respond within 24-48h).
- Day 4-5: hand the broker the pack: IOR name, bond type+number, EORI/EIN, PVA election (UK), IOSS number (EU B2C). The broker's entry quality is downstream of exactly these five fields.
- Ongoing: any new destination country repeats Day 1-5 — the calendar is per-destination, not per-business.
When the registrations are late: the failure mode is uniform — goods arrive, entry can't file, container sits in port storage ($75-350/day by port), the broker adds urgency fees, and your margin math quietly dies in demurrage. The cost teardown carries amortized bond costs; this page carries the calendar that keeps them amortized instead of surprise-billed.
Year-Two Maintenance: What Changes After Your First Year
- Bond renews annually — auto-renewal keeps coverage; keep the invoice into your landed-cost model (the teardown amortizes it for you).
- Importer history compounds: consistent entries under one IOR builds the compliance record that reduces exam rates over time; an entity change resets that goodwill. Consciously decide before switching entities mid-flow.
- De minimis erosion continues — recurring SKU flows shouldn't ride the $800 exemption even where technically possible; the duty guide's standing advice (model everything at full duty) pairs with this page's formal-entry setup.
- Marketplace sellers at scale: once you run FBA-style replenishments, the continuous bond + annual filing cadence is non-negotiable, and IOSS/PVA become monthly bookkeeping lines, not one-time filings. Whether the fee stack justifies holding inventory in FBA at all is a per-SKU call — the channel comparison runs that unit math.
Frequently Asked Questions
What is a customs bond and do I need one to import from China?
A surety guarantee to US Customs that duties, fees and penalties on your entries get paid. Every formal US entry requires one; informal entries under $2,500 generally don't. Ocean shipments formally entered need it regardless of value because of ISF. Continuous bonds ($250-450/year at $50k minimum coverage) for more than a few entries a year; single-transaction bonds ($40-70/shipment) for one-offs.
Can I use my forwarder as the importer of record?
Some forwarders and foreign-importer services offer IOR where you have no entity, but their compliance record covers your goods, and unserupulous services will file risky declarations in their own name with you absorbing the exposure downstream. Import under your own name or entity where practical; use IOR services consciously with document review still yours.
How long does an EORI number take?
GB: typically 1-3 working days. EU member states: same-day to 7, occasionally longer at month-ends. It's free — the cost is calendar. File the week the PI opens so it never sits on the customs documents critical path.
What is IOSS and does my Shopify store need it?
The EU's VAT-at-checkout scheme for consignments under €150 — seller collects VAT at purchase and remits monthly through an EU intermediary. Non-EU sellers must register through the intermediary (€300-500/year + per-return fees). Without it, EU parcels collect VAT + courier disbursement fees at the door — the pattern that kills EU direct-ship conversion.
Continuous bond or single-transaction bond?
More than 3-4 formal US entries a year → continuous (one annual fee covers all entries including ISF, and some entry types require it). One container a year or trialing a lane → STB at $40-70 each. The crossover sits near 5-6 formal entries annually.
Does a small seller really need to worry about all this?
The layer is small-dollar and mostly free — what it costs is calendar. Bonds and IDs filed late convert a routine arrival into port storage charges ($75-350/day) and broker urgency fees. One afternoon of paperwork at PI-signing protects the entire landed-cost model; skipping it is how first containers turn into volunteer donations.
