Container Stuck at a U.S. Port — What Triggers an FDA Import Alert for Food and Supplements

This post is the first in a series on recurring FDA Import Alert patterns by industry. This installment covers food and dietary supplement cases; the next covers medical devices.

Three days after his container cleared Busan and reached the Port of LA, the exporter got a frantic call from his U.S. buyer. Customs wouldn't release the shipment. The paperwork from FDA mentioned something called "DWPE" — the product had been detained automatically, no physical inspection required.

If you export dietary supplements or food to the U.S., you've probably pictured this scenario at some point. A good share of the inquiries we get start exactly here. The problem is, by this point, most of your options are already gone.

What Import Alert and DWPE Actually Mean

An Import Alert is FDA's way of flagging a manufacturing facility or product category as a likely violator. Once something lands on that list, every shipment tied to it gets hit with DWPE — Detention Without Physical Examination. FDA skips the inspection entirely and detains the product on paper alone.

Here's the part people miss: these listings apply to facilities and categories, not just companies. Your firm might have a clean record, but if another shipment from the same manufacturing site — or the same country-of-origin/product category — trips a violation, you can get swept into DWPE right along with it.

Where Food and Supplement Companies Keep Getting Caught

Looking across our cases, the pattern breaks down into three recurring issues.

• Ingredients that are legal here, not there. An ingredient cleared by Korea's MFDS isn't automatically fine with FDA. If it's not on the GRAS list or falls into an unapproved additive category, it gets flagged — companies often don't realize the two countries' standards diverge until it's too late.

• Labeling and claims. Beyond basic Nutrition Facts formatting errors, phrases like "boosts immunity" or "reduces inflammation" on English packaging push FDA to treat the product as an unapproved drug rather than a food. This usually happens when Korean marketing copy gets translated directly without adjustment.

• Gaps with your U.S. Agent. Under FSMA, FDA notifies your U.S. Agent before conducting a foreign facility inspection. If that agent is little more than a mailing address and doesn't relay the notice in time, FDA treats it as a refused inspection — and the entire facility can land on the list before headquarters even knows an inspection was requested.

FDA Import Alert Removal: Process and Strategy

A written explanation to FDA isn't enough to get removed from an Import Alert. FDA's removal requirements are demanding and systematic.

1. Root Cause Analysis: You need to pinpoint exactly what went wrong at the systemic level — not just chalk it up to a one-off mistake.

2. Documented Corrective Action (CAPA): FDA's bar for "corrective" isn't fixing today's problem. It's proving, through a formal process, that it won't happen again.

3. Audit Trail of Clean Shipments: You have to show a track record of consecutive, compliant shipments over a defined period. If even one document turns up flawed during that window, the clock resets to zero.

That's why removal from an FDA Import Alert often takes anywhere from several months to over a year — and the outcome hinges heavily on the order in which documents are submitted and how complete they are.

If Your Container Is Sitting There Right Now

The longer Import Alert and DWPE drag on, the more storage fees pile up — and the more strain it puts on your relationship with your buyer. If you've already received an FDA Notice of Action, or your U.S. Agent has gone quiet on an inspection request, getting the root cause right is the fastest way to cut both the timeline and the cost.
