When a commercial shipment arrives at a port or airport, someone has to file an entry with customs, pay or defer the duty, and arrange release. That someone is either you (self-clearance) or a licensed customs broker acting as your agent. The choice has practical consequences on cost, transit time, and legal exposure.

What a customs broker actually does

A customs broker is a private agent licensed by the destination country's customs administration to file entries on behalf of importers. Brokers do the following:

Classification: assign each line on the invoice to a specific HS code under the destination tariff (HTSUS in the US, TARIC in the EU, UK Global Tariff, ACT in Australia, etc.).
Valuation: declare the customs value, including transport-to-frontier adjustments and royalties where applicable.
Origin determination: claim or decline preferential tariff treatment under any applicable FTA.
Other Government Agency (OGA) filings: FDA Prior Notice for food, USDA APHIS phytosanitary entries, EPA toxic-substances, FCC for radio equipment, ATF for firearms, and equivalents elsewhere.
Entry submission: file the entry via the customs administration's automated system (ACE for the US, CHIEF/CDS for the UK, CHIEF transitional → IPAFFS for UK food, ABF/ICS in Australia, Goods Vector in Canada).
Duty payment: pay duty/VAT directly to customs on the importer's behalf, then bill the importer. Many brokers operate Periodic Monthly Statement (PMS) or duty deferment accounts that defer the payment to a single end-of-month consolidated debit.
Bond and surety arrangement: most countries require an importer-of-record bond. Brokers typically supply a continuous surety bond as part of their service.
Document retention: keep all entry records for the audit retention period (5 years in the US, 6 years in the UK, 7 years in EU for most member states).

A broker generally charges a per-entry fee (USD 50-200 in the US for a basic commercial entry, GBP 50-150 in the UK) plus pass-through duty, plus per-line fees on complex multi-tariff shipments. High-volume importers negotiate flat monthly retainers.

What self-clearance involves

Self-clearance means you, as the importer of record, do everything the broker would do. This is legally available to almost any commercial importer in most jurisdictions, but in practice it requires:

An importer number (US EIN/IRS number, UK EORI, EU EORI, Australian ABN). Free to obtain but requires registration.
Direct access to the customs entry system. In the US that means an ACE Importer Portal account. In the UK, access to the CDS (Customs Declaration Service) requires gateway authentication via HMRC and software that can submit declarations (or HMRC's CDS Trader Tool for occasional importers). In the EU, member-state systems use national customs portals.
A surety bond (US continuous bond or single-entry bond posted with each shipment). UK and EU duty deferment accounts also require a guarantee.
Time and the knowledge to classify correctly. A misclassified entry is the importer's liability. CBP has the authority to assess back duties, interest, and penalties up to 4× the duty value for negligent classification, 8× for grossly negligent or fraudulent.
Sign-off authority on Other Government Agency requirements. If your goods need FDA, USDA, FCC, EPA, CITES, or any of dozens of other agency declarations, you must file the right one. Wrong declarations or missed declarations trigger Cargo Hold orders that can hold the container at the port at USD 200-500/day demurrage.

When self-clearance makes sense

Repeat, simple shipments: a single product (one HS line), single country of origin, no OGA implications, predictable monthly volume. The economics tilt strongly toward self-clearance once you understand the workflow.
Custom-bonded ecommerce: many ecommerce platforms with US fulfilment (Amazon FBA, Walmart MFN, Shopify ShipBob) provide built-in clearance services that effectively self-clear via consolidator brokers.
Bonded warehouse / FTZ operations: if your import enters a US Foreign Trade Zone (FTZ) or UK customs warehouse, the operator handles the bonded entry and you self-file the consumption entries when goods leave the bonded area.
Express-courier shipments: DHL, FedEx, UPS, and DPD provide what is effectively self-clearance by the courier (you sign off on the broker-of-record consent). For shipments under USD 2,500 in the US, the courier's informal entry usually covers it. For larger shipments, the courier acts as your broker for an additional service fee.

When you should hire a broker

Mixed-line shipments with many HS codes, multiple OGAs, or multiple countries of origin.
First-time importer: the cost of getting the first 5-10 entries wrong vastly exceeds the broker's fee.
High-value shipments where a misclassification could trigger a CBP audit covering your last several years.
FTA preferential claims with complex rules of origin (USMCA auto sector, RCEP regional content).
Anti-dumping / countervailing duty merchandise. AD/CVD cash deposits are calculated by CBP at high rates and can be 50-200% of declared value. A broker who knows the case law and the precise scope ruling is worth the cost.
Goods subject to import licensing (rough diamonds, military-list items, dual-use technology, controlled substances).

The broker's legal limits

A broker is not your lawyer and is not allowed to give you legal advice. A broker can prepare and submit an entry but cannot, for example, advise you on whether a transfer-pricing arrangement is consistent with customs valuation rules, or whether a specific manufacturing change would re-qualify your goods under an FTA. For those questions you need a trade-and-customs attorney.

A broker is also not your supplier's representative. The broker acts solely as the importer of record's agent. If your supplier supplies wrong information (incorrect HS, undervalued invoice, mis-declared country of origin), your broker can only enter what you give them; the legal exposure remains yours.

Power of attorney

A broker can act only with a written Power of Attorney (POA) from the importer of record. CBP requires a CBP Form 5291 POA executed by an officer of the importing entity. HMRC requires a Direct Representation declaration. The POA can be limited to specific entries or open-ended; check carefully when you sign.

A common mistake is signing a POA with a freight forwarder who then sub-delegates to a broker without your knowledge. The forwarder is acting as your agent; the broker is acting as your forwarder's sub-agent. Liability still rests with you.

What goes wrong with self-clearance

First-time entries rejected for missing OGA filings: cargo is held until OGA clearance is filed. Demurrage at USD 200-500/day.
Classification errors: silent until CBP runs a focused assessment or trade-show focused on your industry. Years of duty become owed at once with interest and penalties.
Missed FTA claims: the goods clear fine but pay duty at MFN rates because no preferential claim was filed in time. Most jurisdictions allow a post-entry preferential claim within the limitation period but with onerous documentation; many traders just absorb the duty.
Wrong country of origin: country-of-origin marking violations result in CBP detention. Goods must be re-marked or re-exported.
Wrong importer of record: occasionally, a supplier ships DDP (Delivered Duty Paid) and uses your EIN/EORI without authorisation. You're now the importer of record on an entry you never authorised. Reverse this with the customs administration as soon as it surfaces.

For most non-trivial import operations, the brokers' fee is small compared to the avoided downside.
