Between December 1979 and July 1983, United States Tsubaki, Inc., imported 56 entries of roller chains into.this country from Japan. Tsubaki asserted that the merchandise was entitled to enter duty-free, so it made no cash deposit for the merchandise at the time of entry. The entries, however, were subject to an anti-dumping order. In order to determine whether any antidumping duties were owed for those entries, the Department of Commerce conducted administrative reviews for two periods: December 1, 1979, through March 31, 1981, (“the first period”) and April 1, 1981, through September 1,1983, (“the second period”). Liquidation of the entries was suspended pending the final results of those administrative reviews. The results of the first and second reviews were published in the Federal Register on December 4, 1986, and May 8, 1987, respectively.
Roller Chain, Other than Bicycle from Japan; Final Results of Antidumping Duty Administrative Review,
51 Fed.Reg. 43,755 (Dec. 4, 1986);
Roller Chain, Other than Bicycle from Japan; Final Results of Antidumping Duty Administrative Review,
52 Fed.Reg. 17,425 (May 8, 1987). The weighted average final dumping margins were 0.07% for the entries in the first review period and 0.18% to 0.36% for the entries in the second review period. The issuance of the final results had the effect of lifting the suspension of liquidation; the publication of the final results in the Federal Register had the effect of giving notice to the Customs Service that suspension of liquidation had been lifted. See
Int’l Trading Co. v. United States,
Although the antidumping determinations became final in 1986 and 1987, Commerce did not issue liquidation instructions to Customs for the two groups of entries at that time. In fact, Customs did not liquidate the two groups of entries until October 2000 and February 2001. Tsubaki protested the liquidations at that time, contending that the entries were all deemed liquidated by operation of law under 19 U.S.C. § 1504(d) at the rate of duty Tsubaki had declared at the time of entry, which was 0%. After Customs denied the protest, Tsubaki filed this action in the Court of International Trade.
In a thorough opinion, the Court of International Trade held that 51 of the 56 entries were not deemed liquidated and were therefore subject to assessed duties. U.S. Tsubaki, Inc. v. United States, 461 *1334 F.Supp.2d 1339 (Ct. Int’l Trade 2006). The government conceded that the remaining five entries were deemed liquidated at the 0% duty rate. Tsubaki has appealed from the disposition of the 51 contested entries.
. I
As a general matter, if an entry is not liquidated within one year from the date of entry, it is deemed liquidated by operation of law at the rate of duty declared by the importer at the time of entry. 19 U.S.C. § 1504(a). That rule does not apply, however, when liquidation has been suspended either by operation of statute or by court order. Such cases are governed by 19 U.S.C. § 1504(d). The version of section 1504(d) that was in effect between 1984 and 1993 provided as follows:
Any entry of merchandise not liquidated at the expiration of four years from the applicable date specified in subsection (a) of this section, shall be deemed liquidated at the rate of duty, value, quantity, and amount of duty asserted at the time of entry by the importer of record, unless liquidation continues to be suspended as required by statute or court order. When such a suspension of liquidation is removed, the entry shall be liquidated within 90 days therefrom.
19 U.S.C. § 1504(d) (1988). Under that statute, if liquidation was suspended for four years after the date of entry and the suspension was then removed, Customs was directed to liquidate the entry within 90 days thereafter. However, because the statutory command was interpreted as directory and not mandatory, the upshot was that deemed liquidation did not occur in any case in which liquidation was suspended for four years or more.
See Am. Permac, Inc. v. United States,
In 1993, Congress amended section 1504(d). The amended version extended the period of time for liquidating entries after the lifting of suspension of liquidation from 90 days to six months, but it made deemed liquidation mandatory in all cases if liquidation was not effected within that six-month period. 19 U.S.C. § 1504(d) (1994). The new statute provided as follows, in pertinent part:
[W]hen a suspension required by statute or court order is removed, the Customs Service shall liquidate the entry ... within 6 months after receiving notice of the removal from the Department of Commerce.... Any entry ... not liquidated by the Customs Service within 6 months after receiving such notice shall be treated as having been liquidated at the rate of duty, value, quantity, and amount of duty asserted at the time of entry by the importer of record.
This case turns on which version of section 1504(d) applies to the entries at issue. If the pre-1993 version applies, there would be no deemed liquidation, despite the extraordinary delay between the lifting of the suspension of liquidation in 1986 and 1987 and the ultimate liquidation of the entries in 2000 and 2001. If the 1993 version of section 1504(d) applies, however, the entries would be deemed liquidated, since the entries were not liquidated within six months of the lifting of the suspension of liquidation.
II
In order to determine which version of section 1504(d) applies, we must determine what event triggers the statute’s application. Tsubaki argues that the trigger for applying section 1504(d) is the liquidation of the entries in 2000 and 2001. Because those triggering acts occurred after the
*1335
enactment of the 1993 version of section 1504(d), Tsubaki argues, the 1993 version of the statute applies. To support that argument, Tsubaki relies on this court’s decision in
Travenol Laboratories, Inc. v. United States,
Travenol,
which dealt with the accrual of interest, not the suspension of liquidation, has no application to the issue presented in this case. In
Travenol,
we noted that “Customs does not determine whether there has been an overpayment or underpayment of estimated duties until it liquidates or reliquidates an entry.” Because liquidation or reliquidation determines whether the importer has overpaid the applicable duties, we held that liquidation or reliquidation is the appropriate triggering event for the statutory liability for interest on those payments.
Travenol,
In addressing this issue, we do not write on a clean slate. As the trial court noted, this court has already held that.the 1993 version of section 1504(d) should not be applied to cases in which suspension of liquidation was lifted and notice to Customs of the lifting of suspension occurred prior' to the effective date of the 1993 amendment.
See Am. Permac, Inc. v. United States,
In
American Permac,
the importer made three entries of machines that were subject to an antidumping administrative review. The entries were suspended from liquidation pending final resolution of the review. Commerce published the final results of the review, which the importer challenged in the Court of International Trade. During that court’s review, liquidation continued to be suspended. In August 1989, the Court of International Trade affirmed the final results. Suspension . of liquidation was removed at that time, and notice of the lifting of the suspension was given to Customs through publication in the Federal Register.
See Am. Permac,
Applying the 1993 version of section 1504(d), the Court of International Trade held that the entries in
American Permac
were deemed liquidated at the duty rate asserted by the importer at the time of entry.
Am. Permac, Inc. v. United States,
Tsubaki has not pointed to any material difference between this case and American Permac. In American Permac, the lifting of the suspension of liquidation and the accompanying notice to Customs of the lifting of suspension occurred after a court challenge to the final results, whereas in this case, the lifting of the suspension of liquidation and the accompanying notice to Customs of the lifting of suspension occurred at the time the final results were announced (as there was no court challenge to the final results). That distinction, however, makes no difference. In American Permac, as here, the critical, facts — the lifting of the suspension of liquidation and the notice to Customs of the lifting of suspension — occurred prior to the effective date of the 1993 Act. For that reason, the court in American Permac held that the pre-1993 version of section 1504(d) governs, and we are bound by that governing precedent to reach the same result. 1
Tsubaki argues that the portion of the decision in
American Permac
that addresses the triggering event for section 1504(d) is dictum, that we are not bound by that decision, and that we should instead follow the decision of the Court of International Trade in
American International Chemical, Inc. v. United States,
Although we are bound by the prior decision of this court in
American Permac,
and not by the decision of the Court of International Trade in the
American International Chemical
case, we note that
American International Chemical
is distinguishable from both
American Permac
and this case, and it would not provide support for Tsubaki’s claim even if we were to follow it. In
American Permac,
as in this case, the lifting of the suspension of liquidation and the notice to Customs of the lifting of the suspension both occurred prior to the effective date of the 1993 statute. In
American International Chemical,
by contrast, although Commerce was required to publish notice of the final judgment of the court following a challenge to the administrative review of the subject entries, which would have given Customs notice of the removal of the suspension of liquidation, Commerce failed to do so.
Tsubaki makes the further argument that the liquidations in 2000 and 2001 occurred in response to a purported June 9, 2000, email message from Commerce to Customs inquiring about the status of the entries. For that reason, Tsubaki argues, the June 9, 2000, email message should be regarded as the trigger for section 1504(d). The trial court found it unnecessary to address the circumstances surrounding the alleged email message. We also find the alleged email message irrelevant to the proper resolution of the legal issue in this case. Tsubaki contends that even though the lifting of the suspension of liquidation and the original notice to Customs occurred in 1986 and 1987, the June 9, 2000, email message constituted a second notice to Customs. For that reason, Tsubaki argues, the statutory obligation to liquidate the entries should have been triggered by that second notice and should have expired six months after that date. We disagree. Even assuming that such an email message was sent in June 2000 and that it constituted a request to Customs to liquidate the entries, the events that triggered the application of the section 1504(d) obligation to liquidate had already occurred long before, and the issuance of a new message to Customs therefore did not constitute the “notice of the removal” of suspension of liquidation referred to in the statute. We therefore sustain the ruling of the trial court rejecting Tsubaki’s claim with respect to the 51 contested entries.
AFFIRMED.
Notes
. One difference between this case and American Permac is that in this case the liquidations occurred more than six months after the enactment of the 1993 amendment to section 1504(d), while in American Permac the liquidation occurred less than six months after the enactment of the statute. Thus, the six-month period specified in the 1993 statute would not have run at the time the entries in American Permac were liquidated if that period were deemed to have begun running for pre-exist-ing "suspended liquidation” entries on the statute's effective dale. Tsubaki does not argue that that distinction makes a difference, however, and we therefore do not address whether the 1993 version of the statute could be applied to such entries that remained un-liquidated six months after the enactment of the 1993 statute without giving that statute an impermissibly retroactive effect.
