DaimlerChrysler Corporation (“Daimler-Chrysler”) appeals the decision of the United States Court of International Trade denying application of a partial duty exemption pursuant to subheading 9802.00.80 of the Harmonized Tariff Schedule of the United States (“HTSUS”).
DaimlerChrysler Corp. v. United States,
BACKGROUND
The merchandise at issue consists of DaimlerChrysler trucks from the 1993 and 1994 model years. DaimlerChrysler assembled the cargo boxes for the trucks at a plant in Celeya, Mexico, and assembled the complete trucks in Lago Alberto, Mexico. Assembly at both sites involved sheet metal components sent from the United States. As part of the assembly process, DaimlerChrysler subjected the truck cab and cargo box to a complicated treatment process. This process began with the application of a series of coatings to prevent corrosion and similar damage (collectively known as the primer coats). After baking the components to set the primer coats, DaimlerChrysler applied the final two coatings — a color coat and a clear coat (collectively known as the top coats). Because it believed that the painting process was incidental to assembly, DaimlerChrys-ler sought a partial duty exemption under HTSUS 9802.00.80.
Applying its regulation, which distinguishes between decorative and preservative painting, Customs found that Daim-lerChrysler’s application of the top coats did not qualify for duty-free treatment because it was appearance related and therefore not incidental to assembly. Daimler-Chrysler subsequently filed suit in the Court of International Trade challenging Customs’ ruling. That court affirmed Customs’ ruling.
DaimlerChrysler,
DaimlerChrysler filed a timely appeal to this court. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(5).
*1381 DISCUSSION
The interpretation of HTSUS 9802.00.80 is an issue of law and therefore subject to de novo review.
See Rollerblade, Inc. v. United States,
Subheading 9802.00.80 provides duty-free treatment for:
Articles ... assembled abroad in whole or in part of fabricated components, the product of the United States, which (a) were exported in condition ready for assembly without further fabrication, (b) have not lost their physical, identity in such articles by change in form, shape or otherwise, and (c) have not been advanced in value or improved in condition abroad except by being assembled and except by operations incidental to the assembly process such as cleaning, lubricating and painting.
HTSUS 9802.00.80 (emphasis added). With respect to painting, the relevant regulation draws a distinction between preservative and decorative painting. It treats the former as an operation incidental to the assembly process, 19 C.F.R. § 10.16(b)(3), but treats “painting primarily intended to enhance the appearance of an article or to impart distinctive features or characteristics” as an operation not incidental to the assembly process. 19 C.F.R. § 10.16(c)(3).
The issue on appeal is whether Daimler-Chrysler’s painting process, including the application of the primer coats and top coats,' qualifies for duty-free treatment. Particularly, we must decide whether subheading 9802.00.80 unambiguously includes top-coat painting as an operation incidental to assembly.
See Chevron,
I
Subheading 9802.00.80 as well as its reference to painting have been the subject of prior cases. In
General Motors Corp. v. United States,
Subsequent to the
General Motors
decision, the United States Supreme Court addressed the application and interpretation of HTSUS 9802.00.80 in
Haggar I.
In that case, Haggar sent cut fabric, thread, buttons, and zippers to Mexico for final assembly into pants. Upon completion, the pants went through a permapressing operation before being shipped back to the United States. Based on the performance of the permapressing operation, Customs refused to grant Haggar a partial duty exemption. The primary issue before the Court was whether Customs’ regulations implementing the HTSUS were entitled to judicial deference; more particularly, whether they were subject to the analysis required by
Chevron.
In answering that question in the affirmative, the Court specifically considered HTSUS 9802.00.80 and noted that it established two different categories of operations incidental to assembly- — one specific and unambiguous and the other general and ambiguous. “The statute under which respondent claims an exemption gives direction not only by stating a general policy (to grant the partial exemption where only assembly and incidental operations were abroad) but also by determining some specifics of the policy (finding that painting, for example, is incidental to assembly).”
Haggar I,
II
On appeal, DaimlerChrysler primarily argues that the Supreme Court’s analysis in Haggar I provides that painting, with *1383 out limitation, is an operation incidental to assembly. By using the term “painting” generally to describe a category of incidental operations, DaimlerChrysler argues, Congress unambiguously intended to include all painting, regardless of purpose. Because Customs’ regulation regarding painting therefore conflicts with the clear statutory language, DaimlerChrysler continues, the Court of International Trade erred as a matter of law in applying this regulation so as to deny DaimlerChrysler a partial duty exemption. In other words, DaimlerChrysler posits, painting is per se incidental to the assembly process and Customs’ regulation is void as ultra vires. As such, it also believes General Motors was wrongly decided; because the statute is unambiguous, there is no need to resort to legislative history or other extrinsic interpretive aids. In the alternative, Daim-lerChrysler argues that the Court of International Trade erred (1) in applying the regulation to individual layers of paint (rather than the overall painting process, which it found to be primarily preservative); and (2) by interpreting 19 C.F.R. § 10.16(b)(3) to require that the painting operation be “primarily” preservative to be incidental to assembly, despite the lack of such qualifying language in the regulation.
The government counters that the statute cannot be read to cover all painting, only painting incidental to assembly. It argues that DaimlerChrysler reads too much into the Supreme Court’s statements regarding painting in
Haggar I,
which are simply dicta. In addition, it believes that DaimlerChrysler’s interpretation violates basic canons of statutory interpretation and leads to absurd results. According to the government, the context of the Supreme Court’s decision in
Haggar I,
when read in light of the legislative history, actually demonstrates that subheading 9802.00.80 is ambiguous with respect to painting. Consequently, the government believes, Customs’ regulation properly fills a gap and defines the term in a manner consistent with congressional intent. In support of this conclusion, it argues that the Federal Circuit’s decision on remand in
Haggar Apparel Co. v. United States,
We agree with DaimlerChrysler that the Supreme Court in
Haggar I
determined generally that painting is incidental to the assembly process. In order to qualify for the duty exemption, subheading 9802.00.80 requires that articles not be “advanced in value or improved in condition abroad except by being assembled and except by operations incidental to the assembly process such as cleaning, lubricating and
painting.”
HTSUS 9802.00.80 (emphasis added). For purposes of interpreting subheading 9802.00.80, the Court in
Haggar I
found that it established both an unambiguous category and an ambiguous category of operations incidental to assembly. As noted, subheading 9802.00.80 “determin[es] some specifics of the policy (finding that
painting,
for example,
is incidental to assembly
).”
Haggar I,
In light of
Haggar I’s
determination that painting is unambiguously an operation incidental to assembly, we must further determine under step one of
Chevron
whether Customs’ related regulation effectuates congressional intent.
See Chevron,
a mixture of a pigment and a suitable vehicle (as oil, water) that together form a liquid or paste that can be applied and spread ... to a surface so as to form a thin closely adherent coating that dries opaque and imparts color to the surface and that is often designed to protect the surface (as against weathering).
Webster’s Third New International Dictionary 1621 (emphases added). Thus, because Customs’ distinction between decorative and preservative coatings in the regulation, codified at 19 C.F.R. § 10.16(b)(3) and 10.16(c)(3) (distinguishing between decorative and preservative painting), contravenes the plain language of subheading 9802.00.80 as elucidated by the above dictionary definitions, we find that this regulation is invalid under Chevron. We therefore reject the Court of International Trade’s reliance on this regulation to deny DaimlerChrysler its duty exemption based on the top-coat painting operation. Because subheading 9802.00.80 unambiguously covers painting operations broadly, DaimlerChrysler’s entire painting process, including the application of the tops coats, qualifies for the partial duty exemption.
Ill
This court’s prior opinion in
General
Motors,
2
does not preclude our adopting the Supreme Court’s analysis and reasoning in the intervening
Haggar I
decision. “When an opinion issues for the Court, it is not only the result but also those portions of the opinion necessary to that result by which we are bound.”
Seminole Tribe of Florida v. Florida,
IV
The government’s extreme hypotheticals do not convince us that Congress did not unambiguously consider painting to be an operation that is incidental to assembly. In particular, the Court of International Trade and the government on appeal cite theoretical examples of painting a copy of the ceiling of the Sistine Chapel or hot rod flames on the hood of a car. We find such examples unconvincing. As a practical matter, the type of painting cited in these hypotheticals is rarely a part of the automotive assembly process. As Daimler-Chrysler points out, a walk through various showrooms demonstrates that such painting is not standard. Instead, such work typically involves aftermarket customization, not assembly-line operations.
Because we find that subheading 9802.00.80 unambiguously covers painting and that Customs’ regulation is therefore invalid under Chevron, we do not address DaimlerChrysler’s alternative arguments that the Court of International Trade erred in dissecting the painting process and in requiring painting to be “primarily preservative.”
CONCLUSION
We find that the Supreme Court’s decision in Haggar I established that HTSUS 9802.00.80 unambiguously provides that painting is an operation incidental to assembly. As such, Customs’ regulation distinguishing painting based on its preservative or decorative purpose is invalid. Because the Court of International Trade *1386 applied these invalid regulations so as to deny DaimlerChrysler a partial duty exemption for its top-coat painting operation, we
REVERSE.
Notes
. This subheading was the identical precursor to subheading 9802.00.80 of the HTSUS.
. The court in General Motors did not conclude that subheading 9802.00.80 is ambiguous and did not apply a Chevron analysis. Instead, it evaluated the statutory language and its legislative history and applied the Mast Industries factors. Thus, the question of the ambiguity of subheading 9802.00.80 under Chevron remains one of first impression.
.Notably, even if dicta, we would feel obligated to follow the Supreme Court’s explicit and carefully considered statements regarding HTSUS 9802.00.80.
See Ins. Co. of the West
v.
United States,
.We are not convinced by the government's arguments that this court in
Haggar II
recognized that, even for the statutory painting exemplar, the regulations properly delineated between incidental and non-incidental operations. The Supreme Court in
Haggar I
remanded the case to this court for a determination of how the permapressing regulation fares under
Chevron
and the particular facts of the case.
