9903.82.19 Consolidated Metal 232: Aluminum Exemption Heading

Key Points

• 9903.82.19 carries a 0 percent additional duty and functions as an exemption or exception heading within the Consolidated Metal 232 program, not a duty-imposing heading.
• The heading is designated RESERVED for certain aluminum articles under subparagraph (c)(i),(i), with CBP entry instructions listed as pending (status S3) as of August 2026.
• The Consolidated Metal 232 program, including this heading, took effect on 2026-04-06.
• Because CBP entry instructions are still pending, importers should monitor CBP's official guidance channels before claiming this heading on a live entry.
• As with all Chapter 99 codes, 9903.82.19 rides alongside the underlying Chapter 1-97 classification line on the entry; it does not replace it.

9903.82.19 is a reserved exemption heading within the Consolidated Metal 232 program covering certain aluminum articles. It carries a 0 percent additional duty rate, meaning an importer who qualifies to claim it pays no Section 232 surcharge on the covered goods at entry. The heading became effective on 2026-04-06, the same date the broader Consolidated Metal 232 regime launched. Because CBP entry instructions for this heading are still listed as pending, importers must confirm the operational claiming procedure with CBP or a licensed broker before filing an entry under it.

What 9903.82.19 is and what it does

Within the 9903.82 block of the Harmonized Tariff Schedule, individual headings serve different functions. Some impose additional duties on steel, aluminum, or copper imports; others carve out exemptions, exceptions, or zero-rate claims for particular products or country situations. 9903.82.19 falls into the second category. Its official heading text marks it as RESERVED for certain aluminum articles described by subparagraph (c)(i),(i). A "reserved" designation in HTS Chapter 99 typically signals that the heading's product scope or operational instructions are defined by reference to another provision or are still being finalized by the administering agency.

The practical effect is that 9903.82.19 does not itself add cost to an entry. Instead, it is the mechanism by which an importer claims relief from the Section 232 additional duty that would otherwise apply under another heading in the 9903.82 block. Claiming the wrong heading, or failing to claim this one when entitled to it, directly affects the duty bill, so getting the classification right matters.

Affected products and program scope

The facts block identifies the covered goods as certain aluminum articles referenced in subparagraph (c)(i),(i). The HTSUS text and any implementing proclamation or executive order will define the precise product boundaries. Confirm the exact scope in the current HTSUS or with a licensed broker, as the facts available as of August 2026 do not enumerate the specific aluminum product categories beyond that subparagraph reference.

The Consolidated Metal 232 program consolidates the Section 232 treatment of steel, aluminum, and copper articles under the 9903.82 heading block. Other headings in that block address different metals, country-specific surcharges, and derivative products. See the related articles on 9903.82.12 and 9903.82.13 for examples of how other headings in this block operate, and the 2026 tariff code overview for the broader landscape of new Chapter 99 codes this year.

Rate and effective date

The rate is 0 percent additional duty

9903.82.19 imposes no additional Section 232 duty. The 0 percent rate is the rate as of August 2026. An importer claiming this heading correctly pays only the base duty applicable to the underlying Chapter 1-97 classification, plus any other separately applicable tariff provisions (such as antidumping, countervailing, or other Chapter 99 codes that legitimately stack on the same entry line).

Effective date: 2026-04-06

The heading became effective on 2026-04-06, the date the Consolidated Metal 232 regime took effect. Entries of covered aluminum articles filed on or after that date may be eligible to claim 9903.82.19, provided CBP entry instructions are in place and the goods meet the subparagraph (c)(i),(i) criteria. Consult the current Harmonized Tariff Schedule at hts.usitc.gov and CBP guidance at cbp.gov for any updates to the claiming procedure.

How this heading appears on a customs entry

Chapter 99 codes never stand alone on a CBP entry. When an importer claims 9903.82.19, the entry must show two HTS lines for the same goods:

• The standard Chapter 1-97 classification, which determines the base duty rate and statistical reporting.
• 9903.82.19 as a secondary Chapter 99 line, which signals to CBP that the importer is asserting the exemption and that 0 percent additional Section 232 duty applies.

Because CBP entry instructions for this heading are marked as pending (S3) as of August 2026, the specific ACE filing mechanics, including whether a certification, declaration, or other documentation is required, have not yet been published in a CSMS message or formal guidance document. Do not claim this heading operationally until CBP releases those instructions. Monitor cbp.gov and the CSMS message system for the release.

Interaction with other Consolidated Metal 232 provisions

The 9903.82 block contains multiple headings that can intersect with an aluminum entry. The key stacking question for any importer is: which headings apply simultaneously, and which are mutually exclusive?

• Duty-imposing vs. exemption headings: An importer generally claims either a duty-imposing heading or an applicable exemption heading for the same Section 232 program on a given line, not both. 9903.82.19's 0 percent rate is only beneficial if the importer would otherwise owe a Section 232 surcharge under a different heading in the block.
• Other Chapter 99 programs: Additional duty regimes, such as Section 301 tariffs on goods of Chinese origin or IEEPA-based tariffs, are separate and may stack on the same entry line independently of this heading. Confirm all applicable Chapter 99 codes for each shipment.
• Country of origin: Correct country of origin determination is foundational. If origin is disputed or involves third-country processing, review the analysis at China Origin Substantial Transformation for relevant principles, and separately confirm how those principles apply to the aluminum articles in question.
• Russian-origin metals: Separate headings in the 9903.82 block impose elevated duties on Russian-origin steel, aluminum, and copper. See 9903.82.14 for that regime. 9903.82.19 is not a Russia-specific provision based on the available facts.

What importers should do

• Wait for CBP entry instructions before claiming this heading on a live entry. The S3 pending status means the operational procedure has not been published. Filing prematurely may generate ACE errors or require post-summary corrections.
• Confirm product scope against the HTSUS text. Pull the current Chapter 99 text at hts.usitc.gov and verify that your specific aluminum articles fall within subparagraph (c)(i),(i) as defined there.
• Track CSMS messages and Federal Register notices. Subscribe to CBP's CSMS system at cbp.gov and check federalregister.gov for any implementing notices that define the claiming procedure and document requirements for this heading.
• Audit stacking obligations. Confirm all other Chapter 99 codes that apply to the same entry line, including any Section 301 or IEEPA provisions, so the full duty picture is accurate before entry is filed. Use the duty calculator to model the combined rate.
