How to Stay Compliant with Ever-Changing U.S. Customs Regulations

A Complete Guide by Stile Associates – Your Trusted Customs Brokerage Partner

1. Understand the Role of CBP and Key Compliance Areas

CBP enforces laws, collects duties, and ensures legal trade. Importers must master:

• Import Documentation : Invoices, bills of lading, arrival notices
• HTSUS Classification : Using the right tariff codes
• Valuation : Declaring accurate product values
• Country of Origin: Where the goods are actually made
• Duties & Fees: Paid on time and in full
• Security Filings: like ISF and ACE

2. Keep Up with Regulatory Changes (They Happen Often)

CBP rules change fast. Recent updates include:

• New Section 301 tariffs
• Crackdowns on forced labor imports
• Tightened FDA, EPA, USDA regulations
• Migration to the ACE system

Pro Tip: Subscribe to CBP’s CSMS or trust Stile to track it all for you in real time.

3. Correctly Classify Your Goods (HTSUS Codes)

Misclassifying your products means:

• Incorrect duties
• Risk of penalties
• Delays at ports

Always double-check HTSUS codes with Binding Rulings and product specs.

Example: One importer misclassified assembled chairs as parts; and got hit with back duties and fines.

4. File ISF On Time – No Excuses

The Importer Security Filing (ISF) , also called 10+2 , must be submitted 24 hours before loading at origin port.

Late or missing ISFs may lead to:

• $5,000 fines per violation
• Holds, x-rays, and customs exams
• Port delays

Work with Stile , we file ISFs accurately and early, so you don’t have to worry.

5. Use Reasonable Care & Conduct Internal Audits

CBP expects importers to use “Reasonable Care”, which includes:

• Verifying codes and values
• Training your team
• Reviewing documents
• Keeping proper records (at least 5 years)

Internal audits help you catch mistakes before CBP does. We can assist with mock audits too.

6. Understand Partner Government Agency (PGA) Rules

Many imports need approval from other federal agencies:

• FDA – food, supplements, cosmetics
• USDA – meat, plants, grains
• EPA – chemicals, electronics
• CPSC – toys and consumer safety

One mistake in PGA paperwork = customs hold, inspection, or rejection.

Stile pre-checks every shipment to ensure compliance with all PGAs.

7. Prepare for Exams and Holds

CBP may randomly inspect your cargo through:

• Document review
• X-ray (VACIS)
• Intensive inspection
• FDA or USDA lab testing

Always submit clean documents, photograph seals, and use secure supply chains.

Being CTPAT-certified reduces inspection risk.

8. Enroll in CTPAT and Use Trusted Programs

The Customs Trade Partnership Against Terrorism (CTPAT) helps you:

• Speed up clearance
• Avoid unnecessary inspections
• Build trust with CBP

Stile is CTPAT-validated , your cargo moves with priority and peace of mind.

Other helpful programs:

• ACE Portal to track entries
• Duty Drawback to recover paid duties
• USMCA and other FTAs to lower tariffs
