Customs Changes Expected to Halt Most Mailed Prescription Imports

Americans who receive prescription medicines by mail from Canadian and other international pharmacies just received a 90 day delay before facing major interruption to that access. The new date is January 20, 2027.

On October 14, United States Customs and Border Protection (CBP) announced that it plan to implement new entry requirements for mail shipments into the U.S. was being delayed by 90 days. This extension is to provide "importers, brokers, and logistics providers additional time to update their processes while helpin avoid disruptions to certain international postal shipments destined for the United States". The CBP announcement also states that "There are no changes to international mail entry procedures before Jan.20, 2027."

The Canadian International Pharmacy Association (CIPA) is relieved that its member pharmacy businesses will be able to serve their American customers until January 20, though CIPA's assessment is unchanged that the forthcoming U.S. customs requirements will disrupt customers beyond that date. Its conclusion is that, without a change in policy or implementation, the arrangements used to deliver most personal prescription orders to U.S. patients will no longer be workable.

CIPA is sharing this warning so patients can understand the implications and have time to prepare.

How the customs changes affect prescription deliveries

January 20, 2027 is the revised compliance date specified for relevant provisions of the CBP rule published on June 24, 2026. The provisions change the entry procedures applicable to international mail, including shipments requiring additional information for government agencies.

Understanding the consequences for prescription medicines requires looking beyond the filing procedure. A parcel must also meet the conditions applied to the medication itself, and someone eligible must accept responsibility for its customs entry.

CIPA's concern arises from how those requirements will operate together.

The obstacle facing international postal services

A company named Zonos serves as customs broker of record for nearly all major international postal systems. Most of those systems currently have no other broker performing that function.

That makes Zonos's ability to handle pharmaceutical entries central to the continued delivery of mailed prescriptions.

CBP's new rule coupled with the FDA's policy toward imported medications under the new procedures means that Zonos will be prevented from serving as importer of record for shipments containing a pharmaceutical product that is commercially available in the United States.

These restrictions originate with CBP and FDA. They do not reflect a voluntary change in Zonos's business preferences.

The effect of this the problem: CIPA's assessment is that it captures virtually the whole ordinary market for personal prescription orders supplied to Americans by licensed Canadian and international pharmacies.

Why patient documents and electronic filings do not resolve the problem

The limitations described by CIPA are reflected in Zonos's public guidance on prescription medicines. Its explanation of personal importation excludes circumstances where effective treatment is available in the United States. It also makes clear that documents supplied by the patient cannot remedy a seller's promotion of medicines to U.S. residents.

The availability of another customs procedure, known as Entry Type 13, therefore does not establish that these prescriptions can continue to be delivered.

Under CBP's Entry Type 13 notice, the process involves an eligible importer of record, a bond, electronic submission of the entry, and any required agency data. Completing those steps does not remove the conditions governing admission of the medication.

Likewise, the existence of a policy allowing FDA discretion in certain personal-importation cases provides no assurance that a typical order from an overseas pharmacy for personal use in a quantity not exceeding 90 days will qualify. We have no reason to believe that the FDA intends to exercise that discretion in favor of consumers like they did before these new rule is implemented.

Why patients need advance warning

Some readers may expect to find a government announcement explicitly declaring an end to personal prescription imports. The published measure instead addresses customs procedures. Its consequences for patients depend on the requirements applied when their parcels reach the border.

A delivery route can become unusable through the combined effect of those requirements even without a rule expressly announcing a universal ban.

For this reason, CIPA's assessment draws on both the public documents and the implementation information it has received. Its warning concerns the expected interruption of medication deliveries under the arrangements scheduled to apply from January 20, 2027.

Unless those arrangements change, Americans should expect that virtually all routine personal prescription orders mailed from licensed Canadian and international pharmacies will be unable to reach them.

Patients deserve this information before their access is interrupted. CIPA and its members have a responsibility to give them that opportunity; waiting for parcels to be stopped would leave people with less time to make alternative arrangements.
