The declared value for customs is the price you paid or will pay for imported goods, adjusted upward by certain costs the law treats as part of the goods’ true value and stripped of international freight and insurance. U.S. Customs and Border Protection uses that figure to calculate duties, the Merchandise Processing Fee, and any trade remedy charges, so the number on your entry paperwork drives almost every dollar you owe at the border.
Most U.S. tariffs are ad valorem, meaning the duty is a percentage of declared value. Goods valued at $10,000 at a 5% rate produce $500 in duty. The arithmetic is simple; the value itself is not, because federal regulations dictate exactly which costs belong in it.1eCFR. 19 CFR Part 152 – Classification and Appraisement of Merchandise
Building the Number: Transaction Value
Transaction value is the primary method and covers the vast majority of imports. Start with the price actually paid or payable for the goods when sold for export to the United States, then add five categories of cost to the extent they are not already inside the invoice price.2Office of the Law Revision Counsel. 19 USC 1401a – Value
- Packing costs the buyer pays for containers, coverings, and labor to prepare the goods for shipment to the United States.
- Selling commissions the buyer pays in connection with the imported goods.
- Assists: materials, tools, molds, dies, engineering, or design work the buyer supplies to the foreign producer free or at reduced cost.
- Royalties and license fees the buyer must pay as a condition of the sale.
- Any portion of later U.S. resale proceeds that flows back to the seller.
Pay $5,000 for the goods, spend $200 on export crating, and supply an $800 mold the factory uses to make them, and the transaction value is $6,000.3eCFR. 19 CFR 152.103 – Transaction Value
Assists Are the Common Miss
Assists catch out more importers than anything else on the list. Send a foreign manufacturer tooling, design files, molds, or raw materials to use in producing your goods, and the value of those items has to be added. Engineering and design work performed outside the United States and necessary for production also counts. One narrow exception: design work done by a U.S.-based employee of the buyer, incidental to other domestic engineering, is not an assist.4eCFR. 19 CFR 152.102 – Definitions
Royalties: It Depends on the Contract
Whether a royalty gets added turns on two questions. Was the payment required as a condition of the sale, and to whom was it paid? Royalties for patents covering the manufacturing process are generally dutiable. Royalties paid to a third party for the right to use a trademark or copyright in the United States are generally treated as the buyer’s selling expense and stay out. CBP evaluates the specific contract terms case by case.3eCFR. 19 CFR 152.103 – Transaction Value
Related Buyer and Seller
When the parties are related — parent and subsidiary, business partners, family — CBP questions whether the relationship influenced the price. Transaction value still applies if the importer can show either that the price was set the way the seller prices goods for unrelated buyers (or recovers all costs plus a typical profit), or that the declared value closely approximates a “test value” from other accepted methods.5U.S. Customs and Border Protection. Ruling H289520 – Internal Advice on Acceptability of Transaction Value in Related-Party Transactions
What Stays Out
U.S. Customs values goods on a Free on Board (FOB) basis. International shipping and insurance from the country of export are not part of declared value. That matters because many countries use a Cost, Insurance, and Freight (CIF) basis that includes those charges, and a commercial invoice priced CIF must have the freight and insurance backed out before you declare value to CBP.6U.S. Customs and Border Protection. Duty – Cost Insurance and Freight (CIF)
The statute expressly defines the price actually paid or payable as exclusive of transportation, insurance, and related services for the international leg.2Office of the Law Revision Counsel. 19 USC 1401a – Value Post-importation rebates or price cuts between buyer and seller are also disregarded. Value locks in at the time of importation.
When Transaction Value Doesn’t Work
If there is no arm’s-length sale or the price cannot be verified, CBP moves through a fixed hierarchy. First, the transaction value of identical merchandise — goods matching in every respect from the same country and manufacturer.4eCFR. 19 CFR 152.102 – Definitions Then similar merchandise: same country and producer, sharing characteristics, components, and commercial interchangeability.
Next is deductive value. Start with the U.S. sale price of the goods (or identical or similar goods) in the greatest aggregate quantity, then subtract domestic commissions, profit, U.S. transportation, insurance, customs duties, and any value added by processing after import.7eCFR. 19 CFR 152.105 – Deductive Value Last is computed value, built from materials, fabrication, profit, and general expenses in the country of production. An importer can ask CBP to apply computed value before deductive value, though getting the foreign cost data is difficult in practice.
The $800 De Minimis Rule No Longer Applies
Shipments valued at $800 or less used to enter the United States duty-free under Section 321 of the Tariff Act, and that treatment shaped how many importers thought about declared value for small parcels.8U.S. Customs and Border Protection. Section 321 Programs Effective August 29, 2025, Executive Order 14324 suspended duty-free de minimis treatment for shipments from all countries, and the suspension remains in effect in 2026.9The White House. Continuing the Suspension of Duty-Free De Minimis Treatment for All Countries Low-value shipments now owe duties, taxes, and fees like any other import.
Narrow exceptions remain: shipments covered by certain national security provisions at 50 U.S.C. § 1702(b), bona fide personal gifts from a donor who owned the item, and mail consisting solely of documents or letters.10U.S. Customs and Border Protection. E-Commerce Frequently Asked Questions For postal shipments containing merchandise, carriers must collect either the applicable tariff rate or a flat per-package charge ranging from $80 to $200 depending on the tariff rate for the country of origin.11The White House. Suspending Duty-Free De Minimis Treatment for All Countries
Filing the Value on Your Entry
Preparation starts with the commercial invoice from the seller. You need the unit price for each item, the total quantity, the currency, and the correct 10-digit Harmonized Tariff Schedule (HTS) code. The HTS code sets the applicable duty rate; the wrong code produces the wrong amount.12International Trade Administration. Harmonized System (HS) Codes
These details go on CBP Form 7501, the Entry Summary. Importers shipping through couriers typically hand the commercial invoice to the carrier, who transmits the data electronically to CBP before the goods reach the border. Professional importers and customs brokers file directly through the Automated Commercial Environment (ACE) portal.
Every field must match the underlying sales contract or purchase order. If the invoice shows a CIF price, separate the freight and insurance out before entering value. If you supplied assists, reflect them. Errors at this stage are the single most common source of penalty exposure.
Penalties for Declaring the Wrong Value
Civil penalties for a bad declaration are graded by fault under a three-tier system.13Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence
- Negligence, meaning failure to exercise reasonable care: the maximum civil penalty is the lesser of the domestic value of the merchandise or two times the lost duties. If the error did not affect duties, the cap is 20% of the dutiable value.
- Gross negligence, meaning reckless disregard for the accuracy of the declaration: the lesser of the domestic value or four times the lost duties, and 40% of dutiable value if duties were unaffected.
- Fraud, meaning intentional misrepresentation: up to the full domestic value of the merchandise, and CBP can seize the goods.
CBP can assess these civil penalties without a criminal prosecution. Intentional customs fraud also opens the door to criminal charges under separate federal statutes; false entry documents can carry prison sentences of up to two years, and smuggling-related offenses carry substantially longer terms.
Fixing an Error Before CBP Finds It
If you discover a valuation mistake after filing, reporting it voluntarily before CBP starts investigating substantially cuts your exposure. The process is called a prior disclosure.14eCFR. 19 CFR 162.74 – Prior Disclosure
For negligence or gross negligence, a valid prior disclosure reduces the penalty to interest on the unpaid duties. For fraud, the penalty drops to 100% of the lost duties rather than the full domestic value of the goods.13Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence On a $200,000 shipment where duties were underpaid by $10,000, a negligence penalty without disclosure could reach $20,000, while prior disclosure might cost only a few hundred dollars in interest.
To qualify, the disclosure must identify the merchandise, the entry numbers or port and approximate dates, the specific errors, and the correct information. You also have to tender the unpaid duties either at the time of disclosure or within 30 days after CBP calculates the shortfall. An oral disclosure has to be followed in writing within 10 days. Mark the envelope “prior disclosure” and send it by certified mail to lock in the date.14eCFR. 19 CFR 162.74 – Prior Disclosure
Once CBP has commenced a formal investigation, prior disclosure is off the table. CBP records the investigation start date internally, and the importer bears the burden of showing they had no knowledge of it. Disclose early; waiting is a gamble with steep downside.
How Long CBP Can Come After You
CBP has five years from the date of the alleged violation to bring a penalty action for negligence or gross negligence. For fraud, the five-year clock does not start until CBP discovers the fraud, which can extend the window considerably.15Office of the Law Revision Counsel. 19 USC 1621 – Limitation of Actions
You have to keep the paperwork to defend yourself during that window. Every record related to a customs entry — invoices, purchase orders, packing lists, payment records, correspondence with the seller — must be retained for five years from the date of entry.16eCFR. 19 CFR Part 163 – Recordkeeping Willful failure to produce a demanded record can cost up to $100,000 or 75% of the appraised value of the merchandise, whichever is less; negligent failure caps at $10,000 or 40% of appraised value.17U.S. Customs and Border Protection.
