The process in one paragraph
Importing from China to the USA is a five-phase process: classify your product (its HTS code sets the duty), source and verify the supplier, order and produce under clear terms with inspection, ship (typically 25–40 days by ocean), and clear US customs — where your documents, duties, and product compliance are tested. No general import license is required; what is required is getting each phase right in order.
Educational guide, not legal or customs advice: US tariff policy on China-origin goods moves frequently. Verify current rates and rules for your exact product with a licensed customs broker or CBP before pricing an order.
The tariff stack: why "what's the duty?" has three answers
US duty on Chinese goods is a stack, not a single rate. Price your product on the whole stack:
Run the full math — product, freight, stack, fees — in the Landed Cost Calculator before you commit; a product priced on the base rate alone can be unprofitable on the stack.
The de minimis change that rewrote small-parcel importing
The old rule is gone: the $800 duty-free de minimis treatment for China-origin shipments ended in May 2025. Commercial parcels from China now require entry and duties regardless of value. Business models built on duty-free small parcels — classic dropshipping among them — now carry real customs cost and paperwork per shipment. Plan consolidated freight and proper entry instead of many small parcels.
Informal vs formal entry
What is the complete step-by-step method?
1. Classify the product
Find your 10-digit HTS line and price the full tariff stack — the five-step method applies.
3. Order on clear terms
Agree the Incoterm (FOB is the US-lane workhorse — compared here), payment structure, and spec sheet.
4. Line up compliance early
Electronics → FCC; children's products → CPSC; food-contact and cosmetics → FDA. Certificates are production decisions, not shipping paperwork.
5. Produce and inspect
Pre-shipment inspection while rework is possible — the US border is a bad place to discover defects.
6. File ISF, then ship
For ocean cargo, the Importer Security Filing ("10+2") must be lodged before loading in China; then 25–40 days on the water for most lanes.
7. Entry and clearance
Your broker files entry; duties and fees are paid; typical clearance runs days, longer if an exam or agency review triggers.
8. Delivery and records
Final-mile to your warehouse or 3PL — and entry records retained, because importer obligations outlive the shipment.
The documents cbp expects
The China side of a us import, handled
Everything US customs tests was decided weeks earlier in China: the supplier's real identity, the product facts behind the HTS line, the inspection that caught defects before loading, the documents that match the cargo. That is the ground LifaSourcing.com covers from Hangzhou — verification, inspection, and shipping preparation — so what arrives at your broker is a clean file, not a puzzle. US-specific buyer support is outlined on the United States importers page, and the sister lane is covered in Importing from China to the UK.
Mistakes this guide prevents
- Pricing on the base duty alone. The 301 layer and fees are where China-lane margins go to die — price the stack.
- Building on the old de minimis. The $800 exemption for China goods is gone; small-parcel economics changed with it.
- Treating ISF as broker trivia. It's due before loading in China — a timing obligation on your side of the ocean.
- Discovering compliance at entry. FCC, FDA, and CPSC requirements are sourcing-stage decisions; certificates collected after production protect nobody.
