CBP issued a message to trade, and guidance document titled “Post Importation Claims for Preferential Tariff Treatment.”

The purpose of this message is to provide guidance to the trade community concerning acceptable methods for submission of post-importation preference claims, in light of certain judicial decisions. This message is consistent with a memorandum from the Office of International Trade to field offices sent on August 11, 2014.


Historically, importers have used various post-importation mechanisms to claim duty preferences under various free trade agreements, trade preference legislation, and certain tariff provisions in Chapter 98, Harmonized Tariff Schedule of the United States. These mechanisms include Post-Entry Amendments (PEAs), Post Summary Corrections (PSCs), protests in 19 USC 1514 and post-importation claims in 19 USC 1520(d).

Several court decisions1 have held that the protest mechanism set forth in 19 USC 1514 may not be used to make a preference claim, inasmuch as the liquidation of an entry “as entered” (without a claim) is not a “protestable decision”. Headquarters Ruling Letter H193959, dated July 30, 2012, also discussed the court cases’ holding limiting use of protests for preference claims.

However, the implementing legislation for several preference programs specifically provides for post-importation claims, set forth in 19 USC 1520(d), and such claims are the only appropriate mechanism to seek preference when not claimed at the time of entry. This legislation allows post-importation claims for a one-year period after the date of importation.

Customs and Border Protection has completed a review concerning which methods are available to make claims after entry for those preference programs that do not specifically provide for post-importation claims under 19 USC 1520(d). If a preference program does not have a statutory post-importation mechanism, an importer may utilize the PEA or PSC method to make a claim after importation.

For clarity and ease of reference, below is a table of the existing preference programs and the method by which a claim may be made after importation.

19 USC 1520(d)





Civil Aircraft Agreement

Jordan FTA

Chile FTA

Oman FTA

Australia FTA


Morocco FTA

Colombia TPA

Panama TPA

Bahrain FTA

Insular Possessions

The court cases referenced above state that failure to claim preference timely does not give rise to a right to protest. Therefore, importers cannot avail themselves of the protest mechanism in 19 USC 1514 to submit initial claims for preference. Protests filed which are initial preference claims will be rejected by indicating “rejected as non-protestable” in block 18 of CBP Form 19.

For preference programs that by law, have a post-importation provision, a 1520(d) post-importation claim remains the only appropriate mechanism to seek preference when not claimed at the time of importation.

For programs that do not contain a 1520(d) provision, Customs and Border Protection will continue to allow unliquidated entries to be amended by filing a PEA or PSC prior to liquidation in accordance with current PEA and PSC procedures. In conformance with the aforementioned judicial decisions, we note that amendments filed after liquidation will not be treated as protests under 19 USC 1514. Nor will they be regarded as evidence warranting reliquidation under 19 USC 1501.

The Office of International Trade will be revising all guidelines applicable to preference programs to reflect the judicial decisions described above. This message supersedes any conflicting guidance previously published.
