US Customs Clearance for Imports from China: Beginner’s Guide

US customs clearance is the process of getting your shipment legally released into the United States — filing the required paperwork with U.S. Customs and Border Protection (CBP), paying any duties and fees, and passing any inspections, before your cargo can be delivered. If you are importing from China for the first time, this is the step most buyers find confusing. This guide walks you through how customs clearance works, what documents you need, who pays the duties, and how DDP shipping makes the whole process hands-free.

What Is US Customs Clearance?

Every shipment entering the United States must be “cleared” by CBP before it can move past the port or airport. Customs clearance involves three things:

• Filing an entry — submitting the shipment details and commercial documents to CBP.
• Paying duties and fees — the import duty calculated on your goods, plus any applicable processing fees.
• Releasing the cargo — once CBP approves the entry, your goods can be delivered.

Most shipments clear without physical inspection. But CBP can select any shipment for examination, which is why working with an experienced customs broker or forwarder matters.

Who Handles Customs Clearance?

There are two ways to clear your imports, and the difference is central to choosing your shipping method:

• You (or a customs broker you hire) — under terms like FOB or EXW, the buyer is responsible for US customs clearance, hiring a licensed broker, and paying duties.
• Your freight forwarder — under DDP (Delivered Duty Paid), the forwarder handles the entire US clearance process and includes the duties in your all-inclusive price. You do nothing.

If you want to understand the difference between taking this on yourself and letting a forwarder handle it, our guide DDP vs FOB: Which Shipping Method Is Right for You? breaks it down in plain English.

How Does Customs Clearance Work Step by Step?

Here is what happens to your cargo after it leaves China:

1. Your shipment arrives in the USA — at a seaport (for ocean freight) or an airport (for air freight).
2. Your broker files the entry with CBP — usually electronically, before or as the cargo arrives, using your commercial invoice and other documents.
3. CBP assesses the entry — they verify the declared value, classification (HTS code), and origin of your goods.
4. Duties and fees are paid — the import duty, plus fees like the Merchandise Processing Fee (MPF).
5. CBP releases the shipment — or selects it for examination if needed.
6. Your cargo is delivered — by truck from the port or airport to your door, warehouse, or Amazon FBA center.

Under a DDP service, steps 2 through 5 are handled entirely by your forwarder, which is why DDP feels like a single “it just shows up” experience.

What Documents Do You Need for Customs Clearance?

These are the core documents for any commercial import into the USA:

• Commercial invoice — describes your goods, their value, quantity, and the buyer and seller. This is the document customs relies on most.
• Packing list — details how the cargo is packed: weights, dimensions, and carton counts.
• Bill of lading or air waybill — the transport contract issued by the carrier.
• ISF (Importer Security Filing) — also called “10+2,” required for ocean shipments and filed before the vessel departs China.
• Other certificates when applicable — for certain products, such as electronics, textiles, food, or items with specific compliance rules.

Your forwarder will tell you exactly which documents your product needs — another reason DDP is easier for first-time importers who are not sure what applies to their goods.

How Much Are Import Duties from China to USA?

This is the question every importer asks — and the honest answer is: it depends on your product. Import duty is calculated on the declared value of your goods using the product’s HTS (Harmonized Tariff Schedule) classification, and the rate varies widely by product category. Since 2025, trade policy has also changed quickly: the $800 de minimis duty-free exemption for low-value shipments has been suspended for imports from China and all other countries, and China-origin goods can face additional Section 301 tariffs on top of the base duty.

What this means for you in practice:

• There is no “one rate” for China imports — your duty depends on your exact product classification and current policy.
• Duty rates and rules change — trade policy has been especially dynamic recently, so always confirm the current treatment for your product with a professional.
• Under DDP, you do not need to figure this out — your forwarder calculates the duties, includes them in your quote, and handles payment. You see one clear all-inclusive price.

What Is a Customs Bond and Do You Need One?

A customs bond is a guarantee that duties and fees will be paid to CBP. For most commercial shipments entering the USA, a bond is required as part of the entry process. The good news: when you ship DDP, your forwarder arranges the bond for the shipment — you never need to buy one yourself or even think about it.

How Long Does Customs Clearance Take?

Most properly filed entries are cleared within hours to a day or two. The bigger variable is the overall transit time — ocean freight from China to the USA typically takes several weeks door to door, while air freight is measured in days. If CBP selects a shipment for examination, that can add time, which is another reason an experienced forwarder who files things correctly the first time is worth choosing.

What Happens If Something Goes Wrong?

If customs questions your shipment — a valuation issue, a classification question, or a missing document — the entry can be delayed or held. With DDP, your forwarder handles these issues directly with CBP and their broker, and keeps you informed. That protection is one of the biggest reasons importers choose DDP over handling clearance themselves.

Frequently Asked Questions about US Customs Clearance

Do I need a customs broker to import from China?

If you import under DDP, no — your freight forwarder handles customs clearance with their licensed broker. If you import under FOB or similar terms, you are responsible for clearance and will typically need to hire a broker.

Who pays import duties on shipments from China?

Under DDP, the seller or forwarder pays the US import duties and they are already included in your quote. Under other terms, you pay the duties as the importer of record.

Is the $800 de minimis exemption still available?

No. As of 2026, the duty-free de minimis exemption has been suspended for commercial imports — it was ended for goods from China and Hong Kong in May 2025 and suspended for all other countries in August 2025. Even small shipments now require a customs entry and owe applicable duties and fees.

What is an ISF (10+2) filing?

ISF is a security filing required by CBP for ocean imports, submitted 24 hours before the vessel departs China. Under DDP, your forwarder files it for you.

How can I know my total import cost upfront?

With DDP shipping, your forwarder gives you one all-inclusive quote before you ship — freight, duties, fees, and final delivery. That is the simplest way to know your landed cost in advance, with no surprises.

Policy note: US trade policy has been changing quickly. The information above reflects the situation in 2026 — always confirm current duty treatment for your specific product with a licensed professional before shipping.
