Customs Does Not Collect State Sales Tax: Import Duty, Sales Tax, and Use Tax Are Different

Clearing U.S. Customs does not satisfy state sales-tax requirements. Import duties, sales tax, and use tax are separate obligations governed by different laws and authorities.

Federal Import Rules and State Tax Laws Are Separate

A medical device may cross the U.S. border, clear customs, and be delivered without any state sales tax appearing on the customs entry. That does not establish that the transaction is exempt.

U.S. Customs and Border Protection administers federal import requirements, including customs duty and entry fees. State sales and use taxes arise under separate state laws and depend on the transaction, the parties, the destination, and the product’s use.

CBP Does Not Collect State Sales Tax

CBP does not ordinarily assess or collect state sales tax through the customs entry.

Nevertheless, an import can create state sales- or use-tax consequences once the goods enter a state.

Customs brokers, couriers, foreign sellers, or other participants may therefore request a resale or exemption certificate to document that the devices are inventory acquired for resale rather than property purchased for the importer’s own use.

The certificate may support the state-tax treatment or the broker’s invoicing records, but it does not make CBP the state-tax administrator.

Direct Shipments Still Require State Tax Analysis

For a direct shipment to a hospital, practitioner, government entity, or other potentially exempt customer, the state-tax analysis still must be completed.

The product may be exempt by statute, the purchaser may qualify for an entity-based exemption, or the transaction may depend on prescription status or use.

Where an exemption certificate is required, the seller needs a properly completed certificate.

A customer’s assertion that it is “tax exempt,” its federal tax status, or the absence of tax on previous invoices may not be sufficient.

Missing Documentation Can Shift Risk to the Seller

Missing documentation can shift risk to the seller.

An auditor may treat the sale as taxable if the required certificate was not obtained, is incomplete, names the wrong entity, or does not cover the destination state.

The seller may then be assessed for uncollected tax, interest, and penalties.

Nexus Determines Collection Responsibility

The obligation to collect tax depends on whether the seller has nexus and whether the sale is taxable in the destination jurisdiction.

Nexus may arise from economic thresholds or in-state inventory, personnel, representatives, or services.

If the seller is not required to collect—or fails to collect—the purchaser may instead owe use tax on a taxable device stored, used, or consumed in the state.

The Importer of Record Is Not Automatically the Sales-Tax Collector

The Importer of Record is responsible for the customs entry, classification, valuation, and applicable duties and fees.

State sales-tax responsibility follows the domestic sales structure: who sells, invoices, transfers title, accepts payment, has nexus, and claims the exemption.

Those roles may be held by the same company, but they do not have to be.

Align Customs and State-Tax Responsibilities

Under the MDD Options hybrid distribution model, MDD Options can act as the U.S. importing and domestic commercial counterparty, take title upon receipt, invoice customers, manage exemption certificates, and administer registrations, collection, returns, and records.

This removes these responsibilities from the manufacturer while aligning customs and state-tax processes within a controlled U.S. structure.

Where another sales model is retained, MDD Options can provide consulting support to map the parties, nexus, documentation, and use-tax exposures before shipments begin.
