Every commercial shipment entering the United States must go through CBP customs clearance. For a first-time knitwear importer, the process can feel opaque — forms, deadlines, and acronyms that aren't explained anywhere. This guide walks through the customs entry process for a standard ocean freight shipment of sweaters from Turkey, from the ISF filing deadline to the delivery order at your warehouse. Always use a licensed US customs broker for your actual entry — this guide is informational, not legal or customs advice.

Informal vs Formal Entry: The $2,500 Threshold

US Customs distinguishes between two entry types based on the dutiable value of the shipment:

Knitwear export documentation — Turkey to USA, Kiwi Giyim — Packing and export documentation: commercial invoice, packing list, and certificate of origin prepared for US import

Under $2,500

Informal Entry

Simplified process — no formal entry summary required, no customs bond required, no ISF for air freight under $2,500. CBP may still exam the cargo, but clearance is faster. Most sample orders and small test runs fall here. De minimis for personal importation is $800.

$2,500+

Formal Entry

Required for most commercial knitwear shipments. Requires a customs bond, a formal entry summary (CBP Form 7501), and all supporting documents. Duties are assessed on liquidation (the entry is "liquidated" — made final — typically within one year). Your licensed customs broker handles the formal entry.

$250,000+

Entry by Consumption (Large Shipments)

For very large shipments, a consumption entry is the standard mechanism. Same process as formal entry — the bond requirement scales with the shipment value. Large importers typically carry a continuous bond rather than a per-shipment single-entry bond.

Bonded Warehouse

Warehouse Entry (Optional)

Allows you to defer duty payment by storing goods in a CBP-bonded warehouse for up to five years. Useful for managing cash flow on large seasonal orders. Not common for first-time importers but worth knowing about.

The Process: Step by Step

ISF 10+2 Filing (24 Hours Before Loading)

The Importer Security Filing must be submitted to CBP at least 24 hours before the cargo is loaded onto the vessel at the Turkish port (Mersin or Istanbul). Your customs broker files this using 10 data elements you provide (seller, buyer, HTS codes, COO, ship-to party, etc.) plus 2 from the ocean carrier. Late or missing ISF = $5,000 penalty per violation. Send your broker the commercial invoice and packing list at least 72–96 hours before estimated loading.

Pre-Arrival Filing (Entry Preparation)

Once the vessel departs, your broker can begin preparing the formal entry. CBP allows pre-arrival filing up to 5 days before the ship arrives. Pre-filing gives CBP more time to review the entry before the vessel arrives, which can speed up release — especially important during peak season when ports are busy.

Arrival and Entry Filing

When the vessel arrives and unloads at the port (e.g., New York/NJ, Savannah, Charleston), CBP processes the entry. The entry summary (CBP Form 7501) is filed with the classified HTS codes, declared value, duty calculation, and all supporting documents.

CBP Review and Exam Decision

CBP's Automated Targeting System (ATS) reviews the entry and decides on examination. Most entries are released with no physical exam. If an exam is ordered (see below), cargo moves to an exam facility — adding days to your timeline and potentially exam fees.

Duty Payment and Release

If no exam is required (or once an exam clears), CBP releases the cargo. Your broker pays the calculated duties on your behalf (you reimburse them). The cargo is then delivered to your designated deconsolidation warehouse or direct to your facility.

Liquidation (Within ~1 Year)

CBP formally finalizes (liquidates) the entry within one year. If CBP believes duties were underpaid, they can issue a bill for additional duties at liquidation. Keep all entry documents for at least 5 years.

CBP Exam Types

DOC

Document Review Exam

CBP reviews documents only — no physical inspection. Typically resolved within 1–2 days. Most common type; often triggered by the first shipment from a new supplier or country.

CET

Contraband Enforcement Team (X-ray)

Non-intrusive X-ray scan of the container. Usually same day or next day. Cargo stays sealed. Relatively minor delay if the scan clears.

INTENSIVE

Intensive / Tailgate Exam

CBP opens the container and physically examines cargo — counting units, checking labels, verifying fiber content. Can take 3–7+ days. Exam fees (CFS handling, labor) can be $1,000–$3,000+. First-time shipments from a new exporter have slightly higher chance of intensive exam.

TIPS

Trade Intelligence (Issue-Based)

Targeted exam based on a specific trade intelligence flag — UFLPA, anti-dumping, or a CBP alert on the commodity. Less common but can result in significant documentation requests and holds. The main reason to have your compliance documents ready before the ship sails.

Tips to Minimize Delays

File ISF on time — never late, ideally 5+ days before loading
Use accurate HTS codes from the start (mis-classification is a common exam trigger)
Declared value must match the actual commercial invoice — CBP compares prices against market data
Use a customs broker who handles regular apparel imports — they know which CBP ports examine more frequently
Have UFLPA documentation ready before the ship sails — don't scramble to assemble it during a hold
Build 3–5 extra days of port buffer into your delivery timeline, especially for seasonal goods
