A US buyer asking about anti-dumping duties on Chinese solar panels in 2026 is usually not looking for another headline tariff number. They are trying to answer a narrower and more dangerous question: which producer, exporter, product scope, and cash-deposit rate belong in this quote?
That is where AD/CVD gets messy. Anti-dumping duty, or AD, is not the same thing as the 50% Section 301 tariff. Countervailing duty, or CVD, is not the same thing as UFLPA detention risk or FEOC tax-credit eligibility. AD/CVD is a trade-remedy file that depends on Commerce case records, producer status, exporter status, review period, and whether the shipment falls inside the covered product scope.
The practical 2026 answer is this: US AD/CVD orders affecting China-linked solar cells and products remain live, but a buyer should not model them with one generic "China solar tariff" line. The current public AD anchor for the China solar-cell order shows a China-wide AD rate of 238.95%, while several reviewed or separate-rate companies in the 2025 final results show 5.25%. The latest 2026 CVD record is preliminary and shows 9.70% for BYD (H.K.), 0.53% for Vietnam Sunergy, and 8.15% for non-selected companies under review.
Those numbers are not a shopping list. They are a warning. The difference between a reviewed rate and the China-wide rate can make a quote viable or unusable.
Quick Answer
For 2026, US AD/CVD on Chinese solar panels should be treated as a producer-rate file, not a country-rate shortcut.
| Question | Buyer answer |
|---|---|
| Is AD/CVD still active? | Yes. The USITC's 2026 sunset-review decision said existing China/Taiwan solar orders remain in place. |
| Is AD/CVD the same as Section 301? | No. Section 301 is a separate 50% China-origin solar-cell layer. AD/CVD is a trade-remedy rate file. |
| What is the China-wide AD rate? | The current Federal Register AD record states the China-wide entity rate is 238.95%. |
| Are all Chinese suppliers at 238.95% AD? | No. Some reviewed or separate-rate companies may have lower rates; unsupported China-wide exposure can be much higher. |
| What is the latest CVD signal? | Commerce's 2026-06-12 preliminary CVD review lists 9.70%, 0.53%, and 8.15% rates for the reviewed buckets, but those are preliminary. |
| What should a buyer ask for? | Product scope, HTS classification, cell producer, module assembler, exporter, importer of record, AD/CVD case basis, and cash-deposit support. |
- Buyer rule: do not accept "AD/CVD included" unless the supplier or broker can name the producer/exporter basis behind the rate.

Why AD/CVD Is A Different File
Solar buyers often say "tariff" when they mean any government cost attached to an import. That habit creates bad spreadsheets.
In a US-bound China-linked solar shipment, several files can sit next to each other:
| File | What it answers | Why it is separate |
|---|---|---|
| HTS classification | What product line is being entered? | It determines which trade measures even need review. |
| Section 301 | Does the China-origin solar-cell layer apply? | It is a trade-action tariff, not an AD/CVD producer review. |
| AD | Is the product sold below fair value under the relevant order? | It depends on Commerce antidumping records and exporter/producer status. |
| CVD | Did the producer/exporter receive countervailable subsidies? | It depends on subsidy review records and company status. |
| UFLPA | Is the product admissible? | It is a forced-labor traceability file, not a percentage duty. |
| FEOC/PFE | Does the project keep tax-credit value? | It is a project-finance and tax-credit evidence file. |
- Rate note: if a quote collapses all of these into one "China duty" line, the buyer cannot tell which risk is actually being priced.
The right workflow starts with solar-panel-hts-codes-us-imports, then moves to Section 301, AD/CVD, UFLPA, and project-credit review as separate rows.
The Current AD Anchor: 238.95% China-Wide, But Not For Everyone
The key 2026 AD source for this buyer file is Commerce's final antidumping administrative review for crystalline silicon photovoltaic cells, whether or not assembled into modules, from China. The Federal Register final results published on 2025-12-23 cover the 2022-2023 review period.
That notice matters because it makes two things clear.
First, Commerce's final results table gives 5.25% for Shenzhen Sungold Solar and certain separate-rate companies listed in the notice.
Second, the China-wide entity was not under review in that segment, and Commerce states that its dumping margin remains 238.95%. The notice also says that China exporters without a separate rate use the China-wide cash-deposit rate of 238.95%.
| AD bucket | What the notice shows | Buyer meaning |
|---|---|---|
| Reviewed / listed rate table | 5.25% for the listed exporter and separate-rate companies in that review | A named rate can be much lower than the China-wide rate. |
| China-wide entity | 238.95% | Unsupported China-wide exposure can overwhelm the quote. |
| China exporter without a separate rate | Cash deposit equals the China-wide 238.95% | "Chinese supplier" is not enough; rate status matters. |
| Non-China exporter without its own rate | Uses the weighted-average margin applicable to the China exporter that supplied it | A third-country seller still needs upstream China-rate support. |
- Quote note: the commercial question is not "is the company Chinese?" The question is whether the actual producer/exporter path has a defensible separate rate or falls into China-wide treatment.
This is why a US buyer should ask for the exact legal names in the chain. Brand name, sales entity, factory name, cell producer, and exporter are not always the same party.
The Current CVD Signal: Preliminary, Lower, And Still Not Generic
CVD is the subsidy side of the file. It can look less dramatic than the China-wide AD number, but it still matters because it stacks with AD and other duty layers.
Commerce's 2026-06-12 Federal Register preliminary CVD review covers crystalline silicon photovoltaic cells, whether or not assembled into modules, from China for the 2023 period of review. It is preliminary, not final.
The preliminary rates in that notice are:
| CVD bucket | Preliminary subsidy rate |
|---|---|
| BYD (H.K.) Co., Ltd. | 9.70% |
| Vietnam Sunergy Joint Stock Company | 0.53% |
| Non-selected companies under review | 8.15% |
- Timing note: because these are preliminary results, a buyer should not freeze a 2026 quote file around them without broker confirmation and final-results monitoring.
The broader lesson is the same as AD: company status matters. Even a low preliminary CVD number does not make a shipment clean if the producer/exporter identity is uncertain, the cell origin is missing, or the order scope is misunderstood.
Why The USITC Sunset Review Matters
Some buyers hoped the old China/Taiwan solar trade-remedy wall might fade in 2026. That is not what happened.
On 2026-05-27, the USITC said that revoking existing AD/CVD orders on crystalline silicon photovoltaic products from China and the antidumping duty on Taiwan would likely lead to continuation or recurrence of material injury. As a result, the existing orders remain in place.
That decision did not create a new rate. It kept the duty baseline alive.
| What the USITC decision did | What it did not do |
|---|---|
| Confirmed that existing China/Taiwan solar orders remain in place | It did not replace Commerce's company-specific rate records. |
| Preserved the need for AD/CVD screening in US solar quotes | It did not make every China-linked shipment pay the same rate. |
| Reinforced the value of producer/exporter documentation | It did not solve UFLPA, FEOC, or Section 301 questions. |
- Procurement note: the 2026 sunset-review result is a reason to keep AD/CVD rows in the model, not a reason to use a lazy all-in tariff number.
For the timing changes around Section 201 and Section 122, use us-solar-tariffs-2025-vs-2026.
What Products Can Pull AD/CVD Into The Quote
Solar AD/CVD scope language is not always intuitive to buyers because the commercial object is usually a "module" or "panel," while the case language can follow cells, products, and assembly.
The AD and CVD notices cited above both use the phrase "crystalline silicon photovoltaic cells, whether or not assembled into modules." That wording is important. A module quote can still require a cell-origin and cell-producer file.
For a buyer, the practical product questions are:
- Are these loose crystalline silicon PV cells?
- Are these cells assembled into modules or panels?
- Who produced the cells?
- Where were the cells produced?
- Who assembled the module?
- Which exporter is named on the entry path?
- Is the seller a trading company, distributor, brand owner, assembler, or producer?
- Which Commerce order and review period is the broker using?
If the seller cannot answer these questions, the buyer does not have an AD/CVD rate. The buyer has a hope.
How AD/CVD Stacks With Section 301
AD/CVD is not a substitute for section-301-solar-tariffs-china-2026. It can stack with Section 301 where the shipment also falls under the China-origin solar-cell trade-action layer.
That distinction changes supplier conversations. A seller may say "we have a low AD rate." That does not answer whether the Section 301 solar-cell layer applies. Another seller may say "Section 301 is 50%." That does not answer whether the company is exposed to China-wide AD treatment.
| Supplier claim | Missing question |
|---|---|
| "Our AD rate is low." | What about CVD, Section 301, and cell-origin support? |
| "Our product is assembled outside China." | Where were the cells produced, and which orders apply? |
| "Tariffs are included." | Which tariff, which duty, which case number, and which cash-deposit rate? |
| "We ship DDP." | Who is importer of record and who keeps entry records? |
| "The broker confirmed it." | Did the broker confirm in writing with producer/exporter names? |
- Stack note: a defensible model separates Section 301, AD, CVD, Section 122 timing, UFLPA, and FEOC rows before calculating landed cost.
For the broader import workflow, use importing-solar-panels-china-us-2026.
The Producer-Rate File Buyers Should Request
A 2026 AD/CVD file is not a single PDF. It is a packet that lets a broker connect the shipment to the correct order and rate.
| File element | Why it matters |
|---|---|
| Product description | Confirms whether the product is a cell, module, panel, kit, or mixed package. |
| HTS classification | Anchors the entry line and adjacent duty checks. |
| Cell producer legal name | AD/CVD and Section 301 review often start with the cell. |
| Module assembler legal name | Assembly location alone is not enough, but it is still part of the origin file. |
| Exporter legal name | Commerce rates can depend on exporter status. |
| Sales entity and brand name | Helps identify trading-company gaps between quote and producer. |
| Commerce case basis | Shows which AD/CVD order, review, or rate support is being used. |
| Cash-deposit rate support | Prevents vague "included" language from replacing evidence. |
| Change-control clause | Blocks producer, exporter, or cell-source substitution after quote acceptance. |
- Contract note: the file should be attached to the purchase agreement or referenced in a compliance schedule, not kept as an informal sales email.
This is especially important for China-linked modules routed through Southeast Asia. For Cambodia, Malaysia, Thailand, and Vietnam route risk, use southeast-asia-solar-circumvention-duties-2026.
Broker Memo Template
Before a US buyer accepts a China-linked module quote, ask the broker for a written memo that answers these points:
- Product form and proposed HTS classification.
- Whether the product contains crystalline silicon PV cells and whether those cells are assembled into modules.
- Cell producer legal name and country.
- Module assembler legal name and country.
- Exporter legal name.
- Importer of record.
- Applicable AD order or review basis.
- Applicable CVD order or review basis.
- Cash-deposit rate assumptions.
- Whether Section 301 applies separately.
- Whether Section 122 applies for the expected entry date.
- Whether UFLPA traceability has been reviewed separately.
- Whether FEOC/PFE project-credit evidence is needed.
- What happens if the supplier substitutes a producer, exporter, cell source, or assembly location.
That memo does not replace customs counsel. It does keep the buyer from relying on a vague commercial statement.
Red Flags In AD/CVD Solar Quotes
Some quote language should slow the buyer down immediately.
| Red flag | Why it is risky |
|---|---|
| "AD/CVD included" with no producer names | No way to verify the rate basis. |
| "China rate" | There may be reviewed, separate, China-wide, and non-China exporter scenarios. |
| "Factory can change before shipment" | A substitution can change the duty file. |
| "DDP means you do not need documents" | The buyer may still need evidence for audit, lender, tax-credit, or warranty files. |
| "Made in Southeast Asia" | Country label alone does not solve producer/exporter AD/CVD exposure. |
| "CVD is only 0.53%" | That may be preliminary, company-specific, and not applicable to the seller. |
| "No US duties because assembled outside China" | Cell origin and order scope still need review. |
- Decision note: the cheapest quote is often the one with the weakest rate support. That is not a discount; it is an unresolved liability.
What This Means For Landed Cost
AD/CVD can dominate the landed-cost model, but it should not be the only model.
A buyer should build three scenarios:
| Scenario | Use case |
|---|---|
| Supported low-rate case | Supplier and broker provide producer/exporter support for reviewed or separate-rate treatment. |
| China-wide exposure case | Producer/exporter support is missing or the supplier falls into China-wide treatment. |
| Route-change case | Supplier changes cell source, exporter, or assembly location before shipment. |
The result may look less elegant than a supplier quote. It will be more honest.

The cleaner the internal file, the less likely the buyer is to confuse a customs duty, a trade-remedy cash deposit, an admissibility problem, and a tax-credit problem.
FAQ
Are US anti-dumping duties on Chinese solar panels still active in 2026?
Yes. The USITC's 2026 sunset-review decision kept existing China/Taiwan solar trade-remedy orders in place. Buyers still need AD/CVD review for relevant China-linked crystalline silicon PV products.
What is the China-wide AD rate for Chinese solar cells?
The current Federal Register AD final results state that the China-wide entity rate is 238.95%. That does not mean every Chinese supplier pays 238.95%; it means buyers must verify whether the actual producer/exporter has separate rate support or falls into China-wide treatment.
Are AD/CVD duties the same as Section 301 solar tariffs?
No. Section 301 is a separate trade-action tariff layer, currently central to China-origin solar-cell modeling. AD/CVD is a trade-remedy rate file based on Commerce orders, review results, and producer/exporter status.
Do AD/CVD duties apply to modules assembled outside China?
They can still matter if the relevant order scope reaches cells whether or not assembled into modules, or if the route falls under a separate country case. A buyer should not rely on assembly country alone; cell producer, cell origin, exporter, and Commerce case basis all matter.
Can a supplier's DDP quote solve AD/CVD risk?
No. DDP can shift logistics responsibility, but it does not give the buyer a defensible duty file. The buyer still needs producer/exporter evidence, broker support, entry records, and contract terms that allocate duty changes and document failures.
Methodology And Source Notes
This article uses Commerce and Federal Register records for the current AD/CVD facts, including the 2025-12-23 AD final results for A-570-979 and the 2026-06-12 preliminary CVD review for C-570-980. It uses the 2026-05-27 USITC sunset-review release as the source for the conclusion that existing China/Taiwan solar orders remain in place. Section 301, UFLPA, FEOC/PFE, and Southeast Asia route risk are treated as adjacent files and linked to separate China Made & Tech pages to avoid collapsing them into AD/CVD.
