What is a foreign trade zone (FTZ)?

Foreign-Trade Zones (FTZ) are secure areas under U.S. Customs and Border Protection (CBP) supervision that are generally considered outside CBP territory upon activation. Located in or near CBP ports of entry, they are the United States' version of what are known internationally as free-trade zones.

The FTZ program was designed to promote American competitiveness by encouraging companies to maintain and expand their operations in the United States.  The FTZ program encourages U.S.-based operations by removing certain disincentives associated with manufacturing in the United States.

Because FTZs are considered to be outside the Customs territory for the purpose of tariff laws and Customs entry procedures (even though the FTZ is in the U.S.), the import provisions found in Section 801 of the Federal Food, Drug, and Cosmetic Act (the Act) are not applied to foreign products brought into the FTZ. This means that FDA does not determine the admissibility of products brought into the FTZ; rather, FDA will make an admissibility decision when products are withdrawn from the FTZ for consumption.   

Although FDA does not make an admissibility decision when products are brought into the FTZ, FDA does still have jurisdiction over those products. For purposes of the Act, products located within FTZs are regulated under the domestic provisions of the Act until they are offered for entry. Once offered for entry, they are regulated under the import provisions found in Section 801 of the Act. You can find more information regarding FDA’s authority over products located in foreign trade zones in FDA’s Compliance Policy Guide 110.200 and Compliance Policy Guide 110.600.

What is weekly entry filing (WEF)?

CBP has implemented a weekly entry filing (WEF) program allowing customs brokers (entry filers) to submit a weekly estimate for repetitive, high volume entries of low-risk products.  Under this program, a customs broker (entry filer) can submit a single entry estimating the amount of product that will be withdrawn from the FTZ and offered for consumption into the U.S. during the subsequent week.

Some FDA regulated products may be entered via a WEF process. To do so requires a separate request to FDA for participation in WEF processes, and granting of this request. If the request is granted, entries filed under an FDA granted WEF request would not typically be subject to redelivery for sampling or examination by FDA.

What FDA-regulated products are amenable for WEF processing?

Products that are

  • determined by the responsible FDA product center to be “low risk”;
  • in compliance with applicable statutory and regulatory requirements;
  • manufactured, sourced, and/or imported by firms with a history of compliance with FDA regulations; and
  • withdrawn for consumption from a single foreign trade zone.

What happens to my request for WEF processing once it has been submitted to the FDA Import Division office?

The FDA import division office reviews the request to participate in WEF processing for completeness and contacts the WEF requestor if additional documentation or data elements are needed.

The import division also conducts a compliance review to verify:

  • Products are compliant with all applicable FDA requirements;
  • The manufacturers of these products are compliant with any applicable registration requirements; and
  • Neither the products nor the firms that will participate in the weekly entry filing process (i.e manufacturers of the products, shipper, etc.) have a history of non-compliance.

A review of the request for WEF processing may also be required by the applicable FDA center to determine if the products are amenable for WEF procedures because they are “low risk.”

What is the outcome of the FDA review?

Once a decision to grant or deny the request for WEF processing is made, you will receive notification from the FDA import division office indicating the request has been granted or denied.

If the request for WEF processing is granted, FDA will adjust FDA OASIS system screening, to allow for automated processing of future Foreign Trade Zone withdrawal entries (entry type 06). That will allow entries participating in WEF to be given a system “may proceed”.

If the request for WEF processing is not granted, future Foreign Trade Zone withdrawal entries (entry type 06) will be processed the same as other entries. This means that those entries will require submission of entry data at the time of actual withdrawal, and may be subject to document review, field examination and/or sample collection.

Can products participating in WEF be subsequently reviewed and removed from participation?

Yes, if after a request for WEF processing is granted a product later appears to be violative, or if the product appears violative at the time of entry, the FDA import division will evaluate whether continued WEF processing is appropriate. Any violative products collected, or conditions observed during an inspection of the FTZ site, will also cause a review of the WEF request.
