Two Roles, Two Rule Sets
Whether you produce in San Diego or import from Mexico sets your core obligations, and in the CaliBaja corridor many companies do both, developing in San Diego and manufacturing in Tijuana.
| Requirement | If You Produce in San Diego | If You Import from Mexico |
|---|---|---|
| FDA registration | Your domestic facility registers | The Mexican facility registers as foreign; device initial importers register too |
| U.S. Agent | Not required (you're domestic) | Required, including device establishments (21 CFR 807.40) |
| FSVP (food) | Not applicable | Required: you verify the foreign supplier |
| Prior Notice (food) | Not for domestic shipments | Required before each crossing |
| Listing and labeling | Device, drug, or food listing and labels, plus California licenses | Same listing and labeling, plus FDA import review |
Tijuana is minutes away, but it's still Mexico. A device or food crossing at Otay Mesa is a foreign import: the Mexican establishment registers with the FDA and names a U.S. Agent, devices are listed, and food adds FSVP and Prior Notice. Proximity earns no shortcut at the border.
Where Biotech Meets the Border
San Diego is one of the country's leading life-science clusters, and the Torrey Pines and La Jolla corridor is home to drug, biologic, genomics, and medical-device companies. Just south, Tijuana's medical device cluster hosts manufacturing and R&D operations for global companies such as Medtronic, Johnson & Johnson, Stryker, and Boston Scientific (Tijuana EDC). Between them, the Otay Mesa Port of Entry is the busiest commercial vehicle crossing in California (SANDAG), and FDA's Otay Mesa Resident Post covers it (FDA).
For the FDA, that binational model has clear consequences: a device built in Tijuana is an import, so the Mexican establishment registers and names a U.S. Agent, lists its devices, and clears review at the border, while a San Diego developer registers domestically. Add cross-border produce, the Port of San Diego's specialized cargo, and an active sports-nutrition and wellness scene, and most companies here touch FDA rules. For national guidance, see FDA registration services in the United States.
FDA Planning Points for San Diego Companies
Three questions come up on most CaliBaja projects: what a Tijuana-built device needs to cross, where clinical-stage biotech fits, and which California licenses sit alongside the FDA filings.
Tijuana-Built Devices
The Mexican establishment registers, lists, and names a U.S. Agent (21 CFR 807.40), and follows the QMSR, effective February 2, 2026 (FDA). Where a 510(k) or De Novo is needed, it goes through eSTAR unless exempted (FDA).
Clinical-Stage Biotech
Establishments making drugs or biologics only for use under an IND generally do not register and list them until approval (FDA). Commercial manufacturing brings registration, NDC listing, and CGMP, and we plan that transition with you.
California Licenses Sit Alongside FDA
Food and supplement processors and warehousers need a Processed Food Registration from the California Department of Public Health. California also requires a Medical Device Manufacturing License (CDPH) and a state license for drug manufacturers (CDPH), separate from FDA registration.
Nearby service areas: Los Angeles, California, Tijuana, Mexico, and Phoenix, Arizona.

Frequently Asked Questions — FDA Consulting in San Diego, California
Do businesses in San Diego need FDA registration?
Many do. Facilities that manufacture, process, pack, or hold food, drug and biologic establishments, device makers and initial importers, and cosmetic manufacturers generally register with the FDA, and importers need registered foreign suppliers. Some roles do not, such as restaurants, retail stores, and domestic device distributors that do not import (FDA). What you file depends on your role.
What makes San Diego distinctive for FDA compliance?
San Diego pairs one of the nation's leading life-science and medical-device clusters with the Otay Mesa Port of Entry, the busiest commercial vehicle crossing in California and the second largest on the southern border (SANDAG). So FDA work here spans devices, biotech, and drugs, much of it crossing from Tijuana's manufacturing corridor, along with food, produce, supplements, and cosmetics.
We manufacture devices in Tijuana and import them through Otay Mesa — what applies?
Devices made in Mexico are imports. The Mexican establishment registers with the FDA, names a U.S. Agent, lists its devices, and follows the QMSR, and many devices also need a 510(k). The U.S. initial importer registers too. We set up the registration, listing, and U.S. Agent so shipments clear review at the border.
Is Mexico treated as a foreign country for FDA purposes?
Yes. Even though Tijuana is minutes away, goods crossing from Mexico are imports. Mexican food needs foreign facility registration, a U.S. Agent, FSVP, and Prior Notice; Mexican device and drug establishments register as foreign establishments with a U.S. Agent.
Does San Diego's biotech cluster need FDA registration?
Yes, once they manufacture for commercial distribution. Drug and biologic establishments register and list products with NDC codes, and device companies complete establishment registration and device listing. San Diego's Torrey Pines and La Jolla life-science companies fall squarely under these rules.
Does a domestic San Diego producer need a U.S. Agent?
No. A U.S. Agent is only required for foreign facilities. As a domestic San Diego producer or developer you register your own facility, but you don't need a U.S. Agent; that requirement falls on your Mexican or other foreign suppliers if you import.
What is a U.S. Agent for a foreign medical device establishment?
Under 21 CFR 807.40, every foreign device establishment must name a U.S. Agent who resides or keeps a place of business in the United States, to communicate with FDA, help schedule inspections, and respond to questions. For Tijuana device makers shipping into San Diego this is mandatory, and we can serve in that role.
Do imported Mexican produce and food need FDA compliance?
Yes. Produce and food crossing at Otay Mesa are imports: the foreign facility registers, the importer runs FSVP, a U.S. Agent is appointed, and Prior Notice is filed before each crossing. Fresh produce also falls under the FSMA Produce Safety Rule, and just-in-time shipments make getting this right essential.
What's the difference between device registration and a 510(k)?
Establishment registration and device listing tell FDA who you are and what you make; a 510(k) is a separate premarket clearance showing your device is substantially equivalent to one already on the market. Most Class I and some Class II devices are exempt from 510(k) (FDA), but many Class II devices need both, and registration is never clearance.
We're a San Diego startup developing a drug or biologic — when do we register?
Establishment registration and listing apply once you manufacture for commercial distribution. FDA does not require establishments making products only for use under an IND to register and list them until approval (FDA). We help map where registration fits as you move from clinical development toward commercial manufacturing.
Do contract manufacturers in the CaliBaja corridor register?
Yes. A facility that manufactures FDA-regulated products, on either side of the border, registers in its own right. A Tijuana contract manufacturer registers as a foreign establishment with a U.S. Agent; a San Diego one registers domestically.
Do dietary supplement companies in San Diego register?
Yes. Supplements are regulated as foods, so facilities register and follow CGMP under 21 CFR Part 111 with a Supplement Facts label; there is no FDA approval for the supplement itself. San Diego's active nutraceutical and sports-nutrition scene falls under these rules.
Do cosmetics and wellness brands register?
Under MoCRA, cosmetic manufacturers and processors register their facility and the responsible person lists each product, with safety substantiation and adverse event reporting, unless a small-business exemption applies (FDA). FDA does not issue a registration certificate for cosmetics (FDA). This applies to San Diego brands and to cosmetics made in Mexico, where the foreign facility registers.
What is FSVP and when does it apply?
The Foreign Supplier Verification Program is the U.S. importer's duty to verify that foreign food suppliers meet U.S. safety standards. For San Diego importers bringing food from Mexico or elsewhere, FSVP applies, along with foreign facility registration, a U.S. Agent, and Prior Notice.
Can FDA Registration Assistance act as our U.S. Agent or FSVP Agent?
Yes. We serve as the U.S. Agent for foreign facilities, including Mexican device, drug, and food establishments, and the FSVP Agent for imported food, and we manage registrations and listings across every category.
Are you local to San Diego?
We are a U.S.-based firm serving San Diego and the CaliBaja region, alongside clients across the country and 135+ countries, with the same structured process whether you're local, in Tijuana, or elsewhere.
What happens if a cross-border shipment isn't compliant?
FDA can detain, refuse, or place a product on an import alert, stalling a truck and, for just-in-time device lines, a production schedule. Getting registration, listing, FSVP, and a U.S. Agent in place before the crossing keeps freight moving.
Does the Port of San Diego matter for FDA imports?
It can. The Port of San Diego handles specialized cargo, including refrigerated and breakbulk goods, and imported FDA-regulated products arriving there follow the same import rules: facility registration, a U.S. Agent, FSVP for food, and Prior Notice.
Is there an FDA office in San Diego?
Yes. FDA's Otay Mesa Resident Post is at 2320 Paseo de las Americas in San Diego and covers the Otay Mesa (port code 2506), Tecate (2505), and San Ysidro (2504) crossings; the seaport of San Diego (2501) is handled through FDA's Long Beach office (FDA). FDA's headquarters is in Silver Spring, Maryland (FDA). FDA Registration Assistance is a private consulting firm, not FDA.
Does California require its own licenses alongside FDA registration?
Yes, for many companies. Processors and warehousers of food, including dietary supplements, need a Processed Food Registration from the California Department of Public Health, and California requires a Medical Device Manufacturing License for device manufacturers (CDPH) and a license for drug manufacturers (CDPH). These state licenses are separate from FDA registration.
Do you help with eSTAR submissions for 510(k) and De Novo requests?
Yes. FDA requires 510(k) and De Novo submissions to use the eSTAR template unless exempted, while eSTAR is voluntary for PMAs (FDA). We help San Diego device developers and Tijuana manufacturers organize the device description, classification, predicate comparison, and supporting files, alongside registration and listing.
Is a DUNS Number required?
Yes, for food facility registration the DUNS Number is the required Unique Facility Identifier, and drug establishments also provide one. We help you or your foreign supplier obtain one if it isn't already in place.
Does registration need to be renewed?
Yes. Food facilities renew between October 1 and December 31 of each even-numbered year (FDA), cosmetic facility registrations renew every two years, and drug and device establishments renew each year between October 1 and December 31. Device establishments pay an annual fee of $13,785 for FY 2027 (Federal Register). We track renewals so nothing lapses.
Does FDA registration mean FDA approval?
No. Registration and listing are mandatory regulatory steps; they are not FDA approval or endorsement. A device may still need a 510(k), and a drug or biologic its own approval or license, to be marketed.
How long does FDA registration take?
Many registrations and listings are completed within a few business days once your information and any identifiers, like a DUNS Number, are ready. Premarket submissions like a 510(k), FSVP setup, labeling, and California licenses take additional time, and device manufacturers must also meet the Quality Management System Regulation, effective February 2, 2026 (FDA).
We sell devices or supplements online — do FDA rules still apply?
Yes. Online and marketplace sales don't change FDA requirements; establishment registration, listing, and compliant labeling still apply, and marketplaces often request proof of registration before listing. See our guide to FDA compliance for Amazon food sellers.
Can you handle multiple product categories for one company?
Yes. Many San Diego companies span devices, drugs, supplements, and cosmetics; we coordinate registration, listing, U.S. Agent, and FSVP across each category under a single engagement.
