US clearance is where China–USA transit most often loses remaining calendar after a long ocean leg—or after expensive air. The process is CBP-centred. Classification, valuation, ISF discipline, tariff treatment and entry fees decide whether arrival becomes availability.

Documents required for USA customs clearance from China
Commercial invoice with specific descriptions and values
Packing list aligned to invoice
Bill of lading or air waybill
Correct HTS codes
Clear importer of record (IOR)
ISF (ocean) filed on time
PGA evidence (FDA, etc.) when the commodity requires it
⚠️
“Parts”, “gifts” or internal SKUs are not acceptable CBP descriptions.
Duty and HTS on imports from China
Base duty follows HTS. Many China-origin goods also face additional tariffs (e.g. Section 301) by classification—include them in landed cost before locking sales price. Mode does not remove those tariffs: air is not a tax shortcut. Classify first; negotiate freight second.
HTS first. Freight second. Landed cost always.
Entry fees and cash in the USA
Beyond duty, entry may involve fees such as MPF and, on many ocean entries, HMF—verify your entry-type context. They are not surprises if you model landed cost on time. Under DDP, the writing must say who advances duty/fees and how adjustments work if HTS changes on exam.
ISF timing on ocean vs air
On ocean, ISF (10+2) is calendar discipline: late or wrong filings create penalties and holds that erase the sailing. Air has no ocean ISF, but entry and any PGA remain critical on landing day. Do not treat air as an excuse to delay classification.
| Ocean + ISF | File on time with coherent shipper/consignee/HTS |
| Air + entry | Broker ready on landing day; PGA if applicable |
| DDP | Same data requirements—branding does not erase them |
Document quality and holds
Invoice, packing list and B/L/AWB mismatches are a classic exam and dwell cause. Assign a data owner at origin and one at destination. If value or description will be “fixed later,” assume delay and storage cost.
Document quality is an operational control, not administrative courtesy.
Why shipments from China get delayed in the USA
| Late or wrong ISF | Penalties / holds |
| Weak HTS or Section 301 not modelled | Cash surprise + exam |
| Confused IOR | Entry cannot start |
| Late PGA | Arrived but not releasable |
| Terminal free time / dwell | Demurrage that erases the ocean rate |
| DDP without duty/fees scope | Finance dispute at release |
How DDP changes the CBP workflow
DDP can put one owner over brokerage and delivery. It cannot invent HTS, waive ISF on ocean, or erase applicable additional tariffs. Use the USA DDP spoke to audit scope; use this page for CBP mechanics.

Key takeaways for shipping from China to the USA
US clearance rewards preparation on the world’s densest Trans-Pacific lane. LA/LB, NY/NJ, Savannah or ORD cannot fix weak HTS. Only-here: align ISF, HTS and fees with the same-country sea/air/DDP spokes; do not copy an EU (EORI/VAT) playbook onto a CBP entry. Arrival only counts when CBP releases and inland delivers.
