10 Customs Clearance Checks for China to US Forwarders
When a shipment gets stuck at the port, it’s usually not a shipping issue—it’s a paperwork snag that slipped through the cracks.
Most delays with China to US freight come down to a few trouble spots: unclear Importer of Record, missing bond, rushed HTS code, or a late ISF filing. The forwarder you pick should answer specific customs-clearance questions before you book—not after your container is stuck at the port, racking up storage fees.
This checklist covers ten things to confirm with any China to US freight forwarder. Whether it’s your first pallet or your fiftieth container, ask these questions before cargo leaves the factory and you’ll spend way less time scrambling for answers once it’s already at sea.

Confirm the Importer of Record and EIN Before Booking
Every US customs entry needs a named Importer of Record. This party is legally responsible for duties, classification, and the entry’s accuracy—usually your business, tied to your Employer Identification Number.
If your forwarder shrugs off this question or says your supplier will “handle it,” be careful. Your supplier in China can’t serve as the US Importer of Record for a standard commercial import.
Ask your forwarder directly: who do they expect to be listed as importer? Have they confirmed that identity is active in customs records?
A detailed breakdown of importer setup steps shows why this needs to happen weeks before departure, not after arrival.
If the company name or address doesn’t match broker records, entry filing stalls right when you need speed most. Don’t wait until the vessel is close to port to sort this out.

Verify the Customs Broker, Power of Attorney, and Escalation Path
A freight forwarder and a licensed customs broker aren’t always the same. Some forwarders have in-house brokerage, others outsource it. Either way, you need to know who’s actually filing your entry.
Ask which broker will handle your shipment. Will you need to sign a Power of Attorney before departure? This document lets the broker legally act for you with US Customs and Border Protection.
Also, what happens if something goes wrong? Who’s your contact at 9 p.m. if a shipment gets flagged?
A single point of contact, like a dedicated account manager, really matters. Providers like AEB Logistics set things up this way so questions don’t bounce around between departments.
Get the escalation path in writing before you need it—not while your cargo sits in a bonded warehouse.

Check Whether a Continuous or Single-Entry Customs Bond Is Ready
A customs bond guarantees to CBP that duties and fees will be paid. CBP generally requires one for commercial imports valued above $2,500.
There are two types: single-entry bonds for one shipment, and continuous bonds covering multiple entries over a year. If you’re shipping regularly, a continuous bond usually saves money and hassle.
Ask your forwarder if they’ll arrange an annual bond for you, or if you’ll use their bond case-by-case. AEB Logistics, for example, can arrange either depending on your shipment.
Confirm which applies before your first container leaves China. Bond gaps are a common cause of entry delays.

Test the Forwarder’s 10-Digit HTS Classification Review Process
Your HTS code sets your duty rate and triggers government agency reviews. A wrong code can mean overpaying duties—or worse, a compliance flag at the port.
Don’t just accept the code your supplier suggests. Ask your forwarder how they review classification: do they check the current Harmonized Tariff Schedule themselves, or just repeat what’s on the invoice?
Describe your product’s material, function, and use, and see if they can explain the code choice. Vague answers are a red flag. Classification mistakes usually surface only after CBP notices them.

Confirm Who Files the Ocean ISF 10+2 Before Vessel Loading
For ocean shipments, the Importer Security Filing (ISF), or “10+2,” must be submitted at least 24 hours before cargo loads onto the vessel in China. Miss it, and you risk penalties or a shipment hold.
Ask clearly: who files the ISF, your broker or the forwarder? What do they need from you, and by when?
Required data usually includes the seller, buyer, manufacturer, consignee, and HTS classification. If your forwarder can’t explain this timeline, that’s worth noting before you commit to ocean freight with them.

Review the Commercial Invoice for CBP-Ready Product Descriptions
CBP wants plain-language product descriptions. Vague terms like “parts” or “general merchandise” invite extra scrutiny.
Ask your forwarder if they review invoices before departure or just pass along whatever the supplier sends. A good partner will flag a description like “accessories” and ask for specifics: accessories for what, made of what?
This small check, done early, saves a lot of headache when the shipment reaches a US port and an examiner can’t tell what’s inside the box.

Match the Packing List to Cartons, Weights, Pallets, and Shipping Marks
Your packing list, commercial invoice, and bill of lading all have to agree. If carton counts or weights don’t match, CBP will ask questions or delay cargo release.
Ask your forwarder how they reconcile these documents before departure. Do they compare quantities, weights, and shipping marks line by line, or just forward whatever paperwork the supplier provides?
For Amazon FBA shipments, this matters even more. Pallet counts and labeling need to match Amazon’s requirements. Forwarders with FBA experience tend to catch mismatches early.

Ask How Section 301 Duties, MPF, and HMF Are Estimated and Billed
Many goods from China carry Section 301 tariffs on top of standard duty rates. Add in the Merchandise Processing Fee (MPF) and, for ocean freight, the Harbor Maintenance Fee (HMF), and your landed cost can look very different from your product price.
Ask your forwarder for an estimate of these charges before you ship—not after the invoice arrives. A transparent provider should walk you through how each fee gets calculated based on your HTS code and cargo value.
AEB Logistics, for example, can provide duty and tax estimation support when given shipment details and includes customs brokerage costs in its quotes. Ask any forwarder you’re considering to do the same.
Verify FDA, CPSC, FCC, and Other Partner Government Agency Screening
Some products need clearance from more than just CBP. Electronics may need FCC certification, toys and children’s products fall under CPSC rules, and certain goods require FDA registration.
Ask your forwarder if they check for these requirements before booking, or if that’s on you. A good forwarder should at least flag when your product category often triggers agency review.
Skipping this check is a common reason shipments sit in secondary inspection for weeks instead of days.

Confirm CBP Release Monitoring and Port-to-Door Delivery Coordination
Getting cargo released by CBP is only half the job. Someone still needs to track the release, arrange drayage, and get your goods to a warehouse or Amazon fulfillment center.
Ask your forwarder how they monitor release status and what happens the moment cargo clears. Do they update you proactively, or do you have to call and ask?
Real-time tracking with clear shipment milestones—like “Import Entry,” “Import Arrival,” and “Delivered”—helps you plan inventory instead of guessing. Make sure you have this visibility before your first shipment, not during it.

How to Compare China to US Logistics Companies
Ask for Written Responsibility Assignments
Verbal reassurance isn’t enough. Ask each forwarder you’re considering to put in writing who handles Importer of Record setup, broker authorization, bond arrangement, and ISF filing.
If a company won’t commit these roles to writing, that tells you something.
Compare Itemized Quotes Instead of Headline Freight Rates
A low freight rate can hide high customs brokerage fees, bond charges, or accessorial costs added later. Ask for an itemized breakdown that separates freight, customs brokerage, duties, and delivery charges.
AEB Logistics says it can provide an itemized charge breakdown on request. That’s the kind of transparency you should expect from any provider you compare.
Check How the Team Communicates During a Customs Hold
Ask what happens if CBP flags your shipment for inspection. How fast will they notify you, and who’s your point of contact during the hold?
A dedicated account manager model tends to handle this better than a call center rotation. One person already knows your shipment history.

Questions to Ask Before You Approve a Shipment
Who Is Responsible for Each Filing and Deadline?
Get clear, in writing, on who files the entry, who files the ISF, and who confirms the bond. Overlap or gaps between the importer, broker, and forwarder cause most avoidable delays.
Which Charges Are Excluded From the Freight Quote?
Ask specifically about duties, MPF, HMF, Section 301 tariffs, storage fees, and liftgate or residential delivery surcharges. A freight quote rarely includes all of these by default.
What Information Must My Supplier Provide Before Pickup?
Confirm the exact product description, HS code, value, and country-of-origin details your supplier needs to send before cargo leaves the factory. Missing supplier data is one of the most common causes of invoice mismatches at customs.

A Note on Importer Responsibility
Why a Forwarder Cannot Transfer Compliance Liability
A freight forwarder coordinates logistics. It books freight, tracks shipments, and often supports customs paperwork.
But as CBP guidance for importers explains, using a broker or forwarder doesn’t shift your legal responsibility as Importer of Record. You’re still accountable for classification, valuation, and origin information—even if someone else prepares the paperwork.
When to Seek Product-Specific Customs or Regulatory Advice
Every product category carries different rules. Electronics, food-contact items, and children’s products often need specialized review beyond standard customs clearance.
If your goods fall into a regulated category, talk to a licensed customs broker or attorney familiar with that specific product line before your first shipment departs.

Frequently Asked Questions
What documents are required for customs clearance when shipping goods from China to the US?
You’ll usually need a commercial invoice and a packing list. A bill of lading or air waybill is also necessary, and, for ocean freight, you’ll need an Importer Security Filing too.
Depending on what you’re shipping, you might need permits or registrations from agencies like the FDA or CPSC. It’s not always obvious, so double-check before you ship.
How long does customs clearance take for shipments from China to the United States?
If your paperwork’s in order, clearance sometimes happens within a day or two after arrival. But if you’re missing documents, your product descriptions are vague, or a government agency steps in, it can drag on for a week or even longer.
Do I have to pay customs duties and taxes on packages imported from China?
Yes, the Importer of Record pays any duties, taxes, and fees, including Section 301 tariffs if they apply. Amazon won’t act as Importer of Record, so they’ll reject FBA shipments with unpaid duties or shipping charges.
What checks do freight forwarders perform before shipping goods from China to the US?
A good forwarder reviews your HTS classification and makes sure your commercial invoice descriptions are ready for CBP. They’ll confirm bond and broker arrangements and coordinate ISF filing timing for ocean shipments.
But honestly, not all forwarders do every check, so it’s smart to ask them directly.
What happens if US Customs holds or inspects my shipment from China?
CBP can hold your cargo for document review, classification issues, or if another agency wants a closer look. Your broker or forwarder should reach out fast and let you know what’s needed to clear things up—or what extra fees you might face.
How can I avoid customs delays when importing from China to the USA?
Double-check your Importer of Record, broker, and bond setup before your cargo even leaves China. It’s a hassle to fix later, trust me.
Use a commercial invoice with clear, specific product descriptions. Don’t leave anything vague or up to interpretation.
Talk to your forwarder about ISF filing deadlines well before the vessel loads. It’s easy to miss a detail if you wait until the last minute.
