This bill creates a new import charge that scales with the greenhouse‑gas intensity of producing certain industrial goods abroad, with the stated goal of protecting U.S. manufacturers from competition produced under weaker environmental standards. It sets up a statutory framework inside the Internal Revenue Code for calculating a country‑and‑product specific “variable charge,” collects the charge at the time of entry, and directs agencies to develop methodologies, traceability rules, and enforcement tools.
Beyond the fee, the bill establishes a formal pathway—’international partnership agreements’—for foreign countries to receive reduced treatment if they meet monitoring, verification and pollution‑reduction commitments. It also creates facility‑level exceptions, an advisory committee of industry and scientific experts, and compliance procedures that fold into U.S. Customs and Border Protection operations.
For trade and compliance professionals, the bill replaces a simple tariff conversation with a complex emissions accounting and verification regime that will affect pricing, procurement, and supply‑chain governance.
At a Glance
What It Does
The statute requires importers to pay an ad valorem fee at entry equal to the customs value of a covered product multiplied by a country‑and‑product variable charge. The bill provides an initial country/category table that sets interim percentage charges and then transitions to methodology‑driven charges calculated from pollution intensity differences versus a U.S. baseline.
Who It Affects
Importers of heavy industrial inputs (steel, aluminum, cement, glass, fertilizers, certain battery and solar inputs), U.S. manufacturers competing with those imports, U.S. Customs and Border Protection (data intake and collection), Treasury (fee administration), EPA and DOE (methodology and measurement), and USTR (partnership negotiations).
Why It Matters
This is effectively a U.S. carbon‑border adjustment built into the tax code: it forces importers to internalize source‑country emissions performance or negotiate partnership terms to avoid charges, shifting procurement incentives and exposing supply chains to new verification, audit, and valuation rules.

What This Bill Actually Does
The bill inserts a new Subchapter E into the Internal Revenue Code that establishes a fee on imports based on how much greenhouse gas is emitted to produce a ton of an imported good compared with the U.S. production baseline. It delegates technical work to the Treasury Secretary (with EPA, DOE and other agencies), who must convert emissions accounting into a country/product statistical table and issue rules that CBP will use at the point of entry.
The statute anticipates a short interim period (using a pre‑set country/category table) followed by a methodology‑driven system once agencies finalize rules.
Operationally the measure has two distinct pathways. First, an interim regime (the bill provides an initial table) allows immediate application of variable charges while agencies codify measurement methods, HTS classifications, and traceability requirements.
Second, the permanent regime requires the Secretary to publish methods that calculate ‘‘pollution intensity’’ (metric tons CO2e per metric ton of product) using direct, indirect, precursor and transport emissions, and to express intensities at a granular HTS level where possible. The statute mandates public rulemaking, reassessments every three years, and an annual public table mapping HTS 6‑digit entries to the applicable charge.To manage verification and potential strategic behavior, the bill builds several enforcement and compliance hooks.
It requires supply‑chain traceability and document authentication at the time of entry; allows bonds or other securities to be required for fee payment; defines evasion broadly (including fraudulent carbon removal claims); authorizes adjustments and prohibitions where evasion or circumvention is detected; and gives a narrow national‑security carve‑out for DOD contract imports. The bill also creates an advisory committee of sector representatives, lab and scientific experts to assist with methodology and with foreign data verification.The international partnership pathway is a negotiated mechanism — run by USTR at presidential direction — that lets foreign governments and industries gain fee reductions if they adopt interoperable monitoring, reporting and verification systems, commit to pollution‑reduction benchmarks, and accept policies to limit distortive practices (including special rules aimed at nonmarket economy actors and facilities owned or controlled by foreign entities of concern).
For lower‑income countries the statute contemplates temporary phased relief, tied to capacity building, technical assistance, and finance from U.S. agencies.Finally, the bill creates a facility‑specific option: new foreign facilities that meet strict ownership, monitoring, transparency, and verification requirements can be treated at the facility’s measured intensity rather than the host country average — but facilities in nonmarket economy jurisdictions or those owned/controlled by foreign entities of concern are ineligible. The combination of country averages, facility carve‑outs, partnership discounts and traceability requirements makes implementation both a measurement and a trade‑policy exercise rather than a simple tariff adjustment.
The Five Things You Need to Know
The fee is collected at entry as an ad valorem charge equal to customs value × the variable charge applicable to the product and country.
The statute starts with an interim, hardcoded country/category table (in the bill text) and requires agencies to replace it with methodology‑based variable charges after final rules are issued.
A covered importer may be required to post a bond or other security to guarantee fee payment; CBP is the collection point through existing electronic payment portals.
Evasion is defined broadly to include material misstatements, omissions, and fraud involving carbon removal claims; the bill creates a DHS Office of Trade division role to assist enforcement.
New foreign facilities may petition for facility‑specific treatment only if they are post‑enactment, deploy verifiable monitoring (including real‑time data), allow spot inspections, and meet ownership and disclosure tests.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Framing the policy objective
This section articulates the bill’s policy rationale: offset perceived competitive advantages held by foreign producers with weaker environmental controls. It is not operative law but sets the legislative intent that will guide rulemaking, especially when agencies exercise discretion on data gaps, country designations, and partnership eligibility.
Affirms no domestic carbon tax
The bill explicitly bars interpreting the new subchapter as authorization to impose any carbon tax or fee on products produced domestically. Practically, that limits the statutory scheme to imports and narrows legal arguments that the fee could be applied to U.S.‑made goods; administrative rules must respect that textual boundary.
How and when the fee is imposed and collected
This provision creates the legal obligation for the importer of record to pay the fee at entry and gives the Secretary authority to require bonds or other security. It sets a short interim start (the text references an initial, near‑term applicability) and folds fee collection into existing CBP electronic payment processes, meaning CBP will need to adapt entry forms, validations, and payment reconciliation to handle the new line item.
Variable charge mechanics and political multipliers
The statute uses a two‑stage approach: an initial, fixed country/category matrix (in the statutory text) and a transition to a tiered, methodology‑driven charge. It builds in multipliers that raise the charge for products from nonmarket economies and for products made in facilities owned/controlled by designated foreign entities of concern — a deliberate tool to target state‑backed or strategic competitors.
Pollution‑intensity calculation, data sources and verifiability
This section assigns the Secretary responsibility for defining pollution intensity accounting rules, specifying that calculations include direct, indirect, precursor and transport emissions and be as granular as possible (aiming for 6‑digit HTS specificity). It authorizes use of models, facility and satellite monitoring, and publicly available or agency‑accessible data, and requires anonymization of proprietary inputs. It also sets rules for when foreign supplied data may establish alternative intensity values.
International partnerships and covered product scope
These provisions set the legal pathway for negotiated partnership agreements (which can reduce or eliminate fees for partner countries) and list the product categories that are covered (steel, aluminum, cement, glass, fertilizer, certain battery and solar inputs, and related HTS buckets). Practically, that determines where firms should focus compliance and monitoring efforts and where USTR will prioritize negotiations.
Partnerships, advisory committee, traceability and rulemaking timeline
Title II charges USTR with negotiating partnership agreements that require interoperable MRV systems and capacity building (with special timelines for low‑income countries) and makes those agreements subject to publication and Congressional review. The law also creates an advisory committee (sector reps, labs and researchers) to assist Treasury and requires a set of final rules — HTS classification, pollution methodology, traceability requirements and enforcement rules — to be issued on specified schedules and reassessed periodically.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- U.S. manufacturers in covered sectors — the bill aims to narrow cost gaps by making high‑emissions foreign production more expensive, improving price competitiveness for domestic producers.
- Workers in domestic energy‑intensive industries — if the fee preserves market share, it targets job‑risk mitigation in steel, cement, aluminum and related supply chains.
- Countries and foreign producers that accelerate emissions monitoring and reductions — partners with interoperable MRV systems can negotiate fee reductions and faster market access.
- U.S. carbon removal and verification providers — the statute creates demand for verifiable, durable carbon removal offsets and services to demonstrate reductions for foreign producers or facility carve‑outs.
Who Bears the Cost
- High‑emitting foreign exporters (and their governments) — producers in countries with higher pollution intensity will face higher effective import costs and pressure to decarbonize.
- Importers and downstream purchasers in the U.S. — fees, bonding requirements, traceability compliance and potential supply‑chain reshuffling will add compliance costs that may be passed on.
- Federal agencies and CBP — significant implementation, rulemaking, data ingestion, verification and enforcement workloads fall to Treasury, CBP, EPA, DOE, USTR and DHS, likely requiring funding and staffing increases.
- Small importers and intermediaries — those without large compliance teams will incur outsized relative costs to assemble required documentation, traceability claims, and respond to audits.
- Consumers and infrastructure projects — price increases for construction inputs, fertilizers, and some clean‑energy components are plausible if importers pass through higher costs.
Key Issues
The Core Tension
The core dilemma is straightforward: the bill attempts to combine a trade‑protection objective (level the playing field for U.S. industry) with a technically demanding environmental accounting system that must reliably distinguish between cleaner and dirtier foreign production; doing too little measurement risks a protectionist covering of old problems, while over‑reaching, nontransparent or legally fraught accounting invites trade disputes and retaliation.
Measurement and data availability are the bill’s central operational risk. The statute demands granular, production‑weighted pollution intensities down to 6‑digit HTS subheadings where possible, but for many producer countries facility‑level data, reliable grid emission factors, and precursor life‑cycle emissions are incomplete or non‑comparable.
The bill allows agencies to use models, satellite and publicly available data and to apply adverse inferences when data is unavailable, but those choices embed discretion that will determine how punitive or permissive the system actually is.
Trade‑law and diplomacy tensions are acute. The design resembles EU and other carbon‑border adjustment proposals and creates a tool to penalize noncompliant producers, but unilateral multipliers (for nonmarket economies or firms tied to foreign entities of concern) and adverse inference rules create legal exposure under WTO non‑discrimination and national treatment principles.
The administrative complexity — traceability standards, frequent verifications, bond regimes, and facility level carve‑outs — will test CBP capacity and raise confidentiality and commercial‑sensitivity questions about data sharing and aggregation.
