Importer Internal Controls, What CBP Expects During a Compliance Review

1. INTRODUCTION

Importer internal controls are no longer just an accounting or operations issue. They are a customs compliance requirement in practice, because U.S. Customs and Border Protection expects importers to exercise reasonable care when entering merchandise, classifying goods, declaring value, claiming origin, maintaining records, and responding to CBP inquiries.

A compliance review may examine whether the importer has a reliable process to identify errors before entry, correct mistakes after entry, preserve supporting records, and monitor broker filings. CBP’s Focused Assessment program is described as a comprehensive audit that includes an assessment of the importer’s internal control over import activities.

For importers, weak internal controls can create exposure in classification, valuation, country of origin, free trade agreement claims, antidumping and countervailing duties, forced labor reviews, PGA requirements, recordkeeping, and duty payment accuracy. For customs brokers, strong client controls help reduce filing risk, improve documentation quality, and support accurate entry transmission.

2. REGULATORY AND POLICY CONTEXT

CBP’s compliance framework is built around importer responsibility, reasonable care, recordkeeping, and audit authority.

Under 19 CFR Part 163, importers and other covered parties must maintain records and make them available for CBP examination and inspection. The regulation applies to owners, importers, consignees, importers of record, entry filers, agents, and persons whose activities require the filing of a declaration or entry.

The general record retention rule requires records to be kept for five years from the date of entry, or five years from the activity that required the record, unless a specific exception applies.

CBP may demand entry records, and those records generally must be produced within 30 calendar days after the demand, unless CBP approves an additional period. Failure to produce demanded entry records may result in penalties under 19 CFR 163.6.

CBP also publishes guidance on reasonable care and recordkeeping through its Informed Compliance Publications. These publications are important because they explain how CBP expects the trade community to understand and comply with customs requirements. 

3. WHAT CBP OR REGULATORS EXPECT

CBP does not expect every importer to have the same system. A small importer and a multinational importer may have different resources, but both should be able to show that their import process is controlled, documented, reviewed, and corrected when necessary.

1. Written Import Procedures

CBP expects importers to know how their import process works. Written procedures should explain who is responsible for classification, valuation, origin, broker instructions, record retention, partner government agency requirements, and post entry corrections.

A procedure that exists only in employee memory is fragile. If the key employee leaves, the control disappears.

2. Classification Controls

Importers should maintain a process for assigning and reviewing HTS classifications. That process should include product descriptions, technical specifications, binding rulings when appropriate, supplier information, prior classifications, and periodic review.

The risk is not only the wrong duty rate. Misclassification can affect admissibility, PGA requirements, Section 301 duties, antidumping and countervailing duty exposure, quota, marking, and reporting obligations.

3. Valuation Controls

CBP may review whether declared value is supported by commercial invoices, assists, royalties, license fees, related party pricing, packing costs, proceeds, rebates, discounts, and other valuation elements.

A common weakness is relying only on the supplier invoice without reviewing whether additional dutiable amounts exist outside the invoice.

4. Country of Origin and Marking Controls

Importers should have controls to confirm country of origin, marking, preferential origin claims, and origin based duty programs. Origin should not be assumed based only on the shipping country.

For goods involving multiple countries, substantial transformation, tariff shift rules, or regional value content may require deeper review.

5. Broker Instruction Controls

Using a customs broker does not transfer the importer’s compliance responsibility. Importers should give brokers complete, current, and accurate instructions.

A good broker control file should include classification databases, product descriptions, POA records, valuation instructions, origin documents, PGA data, special duty instructions, and escalation procedures for unclear shipments.

6. Recordkeeping Controls

CBP expects records to be retrievable, complete, and organized. The Appendix to 19 CFR Part 163 includes records and information required for entry of merchandise, including entry data, bond information, importer information, country of origin, HTSUS number, value, invoice information, transportation details, and other entry related records.

Electronic record systems are acceptable when they preserve integrity, readability, security, indexing, retrieval, backup, and other requirements. CBP regulations also require yearly internal testing when alternative storage methods are used.

7. Post Entry Review Controls

CBP expects importers to detect and correct errors. A strong internal control program includes periodic review of entry summaries, duty payments, broker transmissions, liquidation status, classification changes, origin claims, and discrepancies between purchase, receiving, accounting, and customs data.

When errors are discovered, the importer should evaluate whether correction is available through a post summary correction, protest, reconciliation, prior disclosure, or another legally appropriate mechanism.

8. Management Oversight

Internal controls are stronger when management reviews compliance reports, open issues, audit findings, broker performance, and corrective actions.

Customs compliance should not operate as an isolated clerical function. It affects cost of goods, duty exposure, financial statements, supply chain continuity, and enforcement risk.

4. COMMON COMPLIANCE GAPS

Importers often face problems during compliance reviews because their process depends on habits instead of documented controls.

Common gaps include:

1. No written import compliance manual.
2. No formal HTS classification review process.
3. Classifications copied from suppliers without independent review.
4. Country of origin assumed from shipping documents instead of production facts.
5. No review of assists, royalties, molds, tooling, or related party pricing.
6. Broker instructions not updated after product changes.
7. Product databases that do not match current commercial descriptions.
8. Entry summaries not reviewed after filing.
9. Missing support for free trade agreement or special tariff claims.
10. Weak document retrieval when CBP issues a record demand.
11. No internal audit schedule.
12. No corrective action log.
13. No escalation procedure for high risk issues.
14. Poor coordination between purchasing, logistics, finance, compliance, and customs brokers.
15. No monitoring of liquidation, refunds, duty increases, or CBP notices.

5. PRACTICAL STEPS FOR IMPORTERS

Importers can reduce risk by building a practical internal control structure that matches their import volume and risk profile.

Step 1. Create an Import Compliance Responsibility Matrix

Identify who owns each compliance function. At minimum, assign responsibility for classification, valuation, origin, broker instructions, PGA data, recordkeeping, post entry review, and CBP responses.

Step 2. Maintain a Product Classification Master File

The file should include item number, commercial description, HTS classification, duty rate, country of origin logic, PGA flags, supporting documents, review date, reviewer name, and notes.

Step 3. Review Broker Entries Regularly

Do not wait for CBP to find errors. Review a sample of entries each month or quarter. Compare purchase orders, invoices, packing lists, bills of lading, entry summaries, and duty calculations.

Step 4. Build a Recordkeeping Index

Create a standard folder or document management structure for each entry. Include the commercial invoice, packing list, bill of lading or airway bill, entry summary, arrival notice, broker correspondence, duty statement, origin documents, PGA records, and supporting valuation documents.

Step 5. Document Corrections

When an error is found, record the issue, affected entries, cause, corrective action, responsible person, and completion date.

Step 6. Train Internal Teams

Purchasing, accounting, logistics, product development, and sales may all create customs risk. Training should explain why product descriptions, invoice values, assists, origin changes, and supplier changes must be communicated before entry.

Step 7. Use Escalation Rules

Certain issues should trigger immediate compliance review, including new products, new suppliers, related party transactions, origin changes, free trade agreement claims, antidumping and countervailing duty exposure, forced labor concerns, FDA or USDA regulated goods, and high value shipments.

Step 8. Conduct Annual Internal Testing

An annual review can test whether the control system is working. For electronic records, CBP regulations specifically reference internal testing of alternative storage systems on a yearly basis. 

6. WHAT IMPORTERS SHOULD PREPARE BEFORE A CBP REVIEW

Before a compliance review, importers should organize the following:

1. Written import procedures.
2. Broker power of attorney records.
3. Product classification database.
4. Valuation support files.
5. Country of origin and marking support.
6. Free trade agreement support, when applicable.
7. PGA documentation.
8. Entry summary review records.
9. Post entry correction records.
10. Record retention policy.
11. Internal audit results.
12. Corrective action logs.
13. Broker instruction records.
14. Management review reports.
15. Copies of CBP notices and responses.

The objective is not perfection. The objective is to show that the importer has a disciplined, documented, and reviewable process.

FAQs.

What are importer internal controls?

Importer internal controls are the policies, procedures, reviews, approvals, records, and corrective actions used to ensure customs information is accurate and supported.

Does using a customs broker remove the importer’s responsibility?

No. The importer remains responsible for exercising reasonable care. The broker helps prepare and file entries, but the importer must provide accurate information and maintain supporting records.

What records should importers keep?

Importers should keep entry records and supporting documents, including invoices, packing lists, transportation documents, entry summaries, classification support, origin support, valuation records, broker instructions, and PGA documents when applicable. 19 CFR Part 163 governs recordkeeping requirements.

How long must import records be kept?

The general rule is five years from the date of entry, or five years from the activity that required the record, unless a specific exception applies.

What happens if CBP demands records?

CBP may require production of entry records. Under 19 CFR 163.6, records generally must be produced within 30 calendar days after the demand, unless CBP approves additional time.

What is the biggest weakness CBP may find?

One of the biggest weaknesses is lack of documentation. Even when the importer believes the entry was correct, CBP may question the filing if the importer cannot produce records supporting classification, value, origin, or admissibility.

Should importers review broker filings?

Yes. Importers should periodically review broker filings against commercial documents and internal product data. This helps identify errors before they become repeated compliance problems.

Are electronic records acceptable?

Yes, but the system must preserve record integrity, readability, security, indexing, retrieval, backup, and other regulatory requirements. CBP regulations also require yearly internal testing for alternative storage systems.
