Complete Guide to Medication Import Rules for Saipan | Explained by a Licensed Pharmacist
Saipan (Northern Mariana Islands) is a popular resort destination, but its healthcare infrastructure is limited. For travelers who require prescription medications or regularly take over-the-counter medicines, understanding medication import rules is essential. As a U.S. territory, Saipan enforces strict regulations aligned with U.S. law. This article, compiled from a pharmacist's perspective, provides practical guidance on how to bring medications safely and what to avoid.
Basic Rules for Importing Medications to Saipan
U.S. Customs Compliance | Personal Use Only
Saipan is U.S. territory, and all medication imports fall under the jurisdiction of the U.S. Food and Drug Administration (FDA). The basic principles are as follows:
| Item | Rule |
|---|---|
| What can be imported | Personal use only (commercial or resale purposes strictly prohibited) |
| Quantity guideline | Approximately one month's supply (up to 90 days is acceptable) |
| Packaging | Original containers with labels intact |
| Customs declaration | Not required (but disclose if asked by officials) |
| Inspection focus | Liquid and gel-form medications are subject to stricter scrutiny |
Pharmacist's note
The definition of "personal use" medications is somewhat ambiguous, but generally means 90 days' supply or less with no commercial intent. Supplements and vitamins may be classified as medications and subject to the same rules.
Essential Requirements for Importing Prescription Medications
Preparing Prescriptions and English Medical Certificates
If you are bringing prescription medications, you must prepare the following:
-
Copy of Japanese Prescription
Obtain a copy from your prescribing physician in Japan and keep the original or a copy in your suitcase. U.S. customs officials may verify the medical appropriateness of your medications. -
English Prescription or Medical Certificate
Request your Japanese physician to prepare an "English Medical Certificate."
The document should include:- Patient name (matching your passport exactly)
- Medication name (generic and brand name)
- Dosage and frequency
- Duration of prescription
- Physician's signature, seal, and contact information
-
Original Medication Container
Ensure the following information is clearly visible:- Patient name
- Medication name (brand and generic)
- Dosage
- Dispensing date and expiration date
- Name of dispensing pharmacy
| Document | Essential | How to Obtain |
|---|---|---|
| English medical certificate | ★★★ | Request from prescribing physician (typically ¥1,000–¥3,000) |
| Prescription copy | ★★★ | Request from pharmacy |
| Original container | ★★★ | Bring as-is |
| Medical handbook | ★★ | Useful if you have chronic conditions |
Pharmacist's note
While customs officials in Saipan rarely request medical records, customs inspectors may make medical judgments about your medications. An English medical certificate provides objective proof of legitimacy and helps avoid complications at customs.
Tips for Importing Over-the-Counter Medications
OTC Medications Are Relatively Flexible | But Caution Is Advised
Over-the-counter (OTC) medications are subject to less stringent rules than prescription drugs, but the following precautions apply:

Absolutely Prohibited Medication Ingredients and Drugs
U.S.-Regulated Medication Ingredients
The following active ingredients are prohibited or severely restricted from import. If any of your medications contain these, you must prepare an English medical certificate:

Pharmacist's note
Special caution: Multi-symptom cold remedies
Some Japanese cold medicines like "Biofermin S" or "Lulu" may contain ephedrine, which is regulated in the U.S. Verify ingredient lists in English or contact a pharmacist. Many product packages include QR codes linking to ingredient information.

Strict Handling of Liquid and Gel-Form Medications
Why Subdividing into 100ml Containers Should Be Avoided
Liquid medications receive particularly close scrutiny at Saipan customs. Pay attention to the following:
| Liquid Medication Type | Import Tips |
|---|---|
| Prescription liquid medications (injectables, etc.) | Physician prescription required. Keep original labels even if under 100ml |
| Syrups and liquid formulations | Keep in original container when possible. Avoid subdividing |
| Eye drops and nasal sprays | Original container only. Carry-on limited to 100ml or less |
| Ointments and creams | Keep in original tubes (avoid small subdivided containers) |
Pharmacist's note
In-flight liquid restrictions (100ml or less) are separate from customs medication regulations.
Prescription medications exceeding 100ml in liquid form are generally permitted in checked baggage, but having an English medical certificate demonstrating medical necessity provides added certainty.

How to Obtain or Purchase Medications Locally
