Every shipment entering the United States passes through US Customs and Border Protection (CBP). For importers, understanding how US customs clearance works — from the earliest pre-arrival filings to final cargo release — is the difference between predictable supply chains and expensive delays.
BorderTek Solutions coordinates US customs clearance through a broker network with deep experience across commercial goods, vehicles, industrial equipment, and regulated commodities. Here's the full picture.
The US Customs Clearance Timeline
US customs clearance is not a single event — it's a sequence of steps that begins before your cargo departs and ends when CBP formally releases the goods into US commerce.
Stage 1: Pre-Shipment Compliance Review
Before cargo loads at the origin port, importers should have:
- Confirmed the correct Harmonized Tariff Schedule (HTS) code for all commodities
- Determined applicable duty rates
- Identified any required partner government agency (PGA) filings (FDA, USDA, EPA, FCC, etc.)
- Screened all parties against denied party lists
BorderTek's broker partners complete this pre-shipment review to identify compliance requirements before the cargo moves — not after it arrives at a US port.
Stage 2: ISF Filing (Ocean Freight)
For ocean freight, the Importer Security Filing (ISF) — commonly called "10+2" — must be filed with CBP at least 24 hours before cargo is loaded at the foreign port. The ISF includes 10 data elements from the importer and 2 from the carrier. Late ISF filing triggers fines of up to $5,000 per violation.
Stage 3: Entry Filing
When the vessel or truck approaches the US port of entry, your customs entry must be filed. CBP requires entry filing within 15 calendar days of cargo arrival (for ocean freight) before goods are deemed abandoned. Entry types include:
- Formal Entry (Type 01): Required for shipments valued over $2,500 — the standard for most commercial imports.
- Informal Entry (Type 11): For lower-value shipments.
- Consumption Entry: The most common entry type — goods released directly into US commerce.
- Warehouse Entry: Goods stored in a bonded warehouse before being released to commerce.
Stage 4: CBP Examination
CBP uses a risk-based targeting system to select shipments for examination. Examination types range from document review (least intrusive) to intensive exam (full unloading and inspection). BorderTek's broker partners work to minimize examination frequency through accurate, complete documentation.
Stage 5: Duty Assessment and Payment
CBP calculates duties based on the HTS classification and the declared value of the goods. BorderTek's broker partners apply a detailed classification process to ensure your goods are correctly classified — avoiding both overpayment and the compliance exposure of misclassification.
Stage 6: Cargo Release
Once CBP is satisfied with the entry, duties are paid (or a bond covers payment), and all PGA requirements are met — the cargo is released. For most formal entries, this takes 1–5 business days absent examination.
HTS Classification: The Foundation of Customs Compliance
Every imported commodity must be classified under the Harmonized Tariff Schedule of the United States (HTSUS). The HTS code determines:
- The applicable duty rate
- Whether any trade remedy tariffs apply (Section 301, Section 232, antidumping/countervailing duties)
- Which partner government agencies have jurisdiction
- Whether USMCA or other free trade agreement benefits apply
Misclassification is one of the most common — and costly — customs compliance failures. CBP has the authority to assess back duties, interest, and penalties on misclassified goods going back five years. BorderTek's broker partners apply a detailed classification process to every commodity, including complex goods that span multiple HTS chapters.
FDA Prior Notice and Other Partner Government Agency Requirements
CBP does not regulate imports alone. Dozens of US agencies have jurisdiction over specific commodity types, and CBP will not release goods until PGA requirements are met. Common PGA requirements include:
FDA Prior Notice: Required for all food, beverage, dietary supplement, drug, and cosmetic imports. Must be filed electronically before the shipment arrives at the US port.
USDA/APHIS: Required for agricultural products, plants, soil, and certain animal products.
EPA: Required for vehicles, engines, pesticides, and certain chemicals.
FCC: Required for electronic devices that emit radio frequency energy.
BorderTek's broker partners identify all applicable PGA requirements during pre-shipment review and file all required notices before cargo arrives.
Antidumping and Countervailing Duties: A Growing Risk
US trade remedy tariffs — including antidumping (AD) and countervailing duty (CVD) orders — have expanded significantly over the past decade. These tariffs are applied on top of standard duty rates and can be substantial (sometimes exceeding 200%).
AD/CVD orders are commodity and country-specific. If your goods fall within the scope of an AD/CVD order, you must deposit the applicable duty rate at the time of entry. BorderTek's broker partners monitor active AD/CVD orders and apply them accurately to your entries.
Customs Bonds: What They Are and Why You Need One
Any importer filing a formal entry must have a CBP customs bond on file. The bond is a financial guarantee to CBP that duties, taxes, and penalties will be paid. Options include:
- Single-entry bond: Covers one specific shipment.
- Continuous bond: Covers all entries for a 12-month period. Required for importers with more than a few entries per year.
BorderTek's broker partners manage bond procurement and maintenance as part of the full customs clearance service.
