Brasilia renews its 21.6 percent anti-dumping duty on Chinese suspension PVC resin for up to five more years while the companion measure on South Korean resin stays terminated, cementing a split outcome in a trade defense case that has run for nearly two decades.
BRASILIA, August 7, 2026
Brazil will keep its anti-dumping shield against Chinese polyvinyl chloride in place into the next decade. The Executive Management Committee of the Chamber of Foreign Trade, the body known as GECEX that decides trade remedy matters within Brazil’s foreign trade chamber Camex, adopted Resolution No. 947 on August 4, 2026, extending the definitive anti-dumping duty applied to Brazilian imports of polyvinyl chloride resin obtained by the suspension process, the workhorse commodity plastic known in the trade as PVC-S, originating in the People’s Republic of China. The measure was published in the Diario Oficial da Uniao, Brazil’s federal gazette, on August 6, and provides for renewal of the duty for a period of up to five years.
The decision was recorded on August 7, 2026 by Global Trade Alert, the independent monitoring service operated by the St. Gallen Endowment for Prosperity through Trade, under intervention number 19165. The entry captures the split outcome that has come to define this long-running case: the duty on Chinese resin is extended once again, while the parallel duty that once applied to South Korean producers stands terminated. Brazilian regulators allowed the Korean leg of the measure to lapse after finding no likelihood that shipments from South Korea would resume injuring the domestic industry, and the new resolution consolidates that divergence for another five-year cycle.
According to the official summary published in the gazette and circulated by Brazilian customs broker associations, including the Sao Paulo customs brokers union SINDASP and the foreign trade services union SINDICOMIS, Resolution No. 947 renews the duty on PVC-S commonly classified under subheading 3904.10.10 of the Mercosur Common Nomenclature, to be collected in the form of an ad valorem rate applied to the customs value of the merchandise. The text adds that the tariff classification is merely indicative and carries no binding effect on the scope of the anti-dumping measure, standard drafting language intended to discourage circumvention through creative reclassification at the border.
The duty in force, according to the registry of trade remedies maintained by the Ministry of Development, Industry, Trade and Services, is 21.6 percent ad valorem, applied uniformly to the named Chinese producers Shanghai Chlor-Alkali Chemical, Suzhou Huansu Plastics, Tianjin Dagu Chemical and LG Dagu Chemical, and to all other Chinese exporters of the product. That single rate has anchored the measure through each of its renewals, an unusually flat structure in a policy area where company-specific margins often vary widely.
A Renewal Years in the Making
The extension closes a sunset review that formally began on August 14, 2025, when SECEX Circular No. 63 of August 13, 2025 was published in the federal gazette. The circular, issued by the Foreign Trade Secretariat, SECEX, on the recommendation of its Department of Trade Remedies, DECOM, initiated the end-of-period review of the duty then in force and confirmed that the measure would remain applicable while the review ran its course, as Brazilian law provides. The review was requested by the two companies that constitute Brazil’s domestic PVC industry, Braskem S.A. and Unipar Indupa S.A.
An analysis of the initiation published by lawyers Marina Takitani and Caroline Dias on the Chambers and Partners legal platform in August 2025 laid out the review’s parameters. The investigation examined the likelihood of continuation or resumption of dumping over the period from January to December 2024, and the likelihood of continued or recurring injury to the domestic industry over the five years from January 2020 to December 2024. Because Chinese import volumes during the dumping period were not considered representative, the authority analyzed the probability of recurrence of dumping rather than calculating fresh margins, and the recurrence margins used for initiation purposes were not disclosed. The same analysis noted that DECOM recommended opening the review in light of evidence suggesting that termination of the measure would most likely lead to the resumption of dumping in Chinese exports and the recurrence of the injury flowing from it.
The procedural clock then ran with unusual precision. SECEX Circular No. 98 of December 18, 2025 fixed the deadlines for the remainder of the proceeding under Decree No. 8.058 of 2013, Brazil’s anti-dumping regulation. The evidentiary phase closed on March 23, 2026, the technical note setting out the essential facts under analysis was scheduled for May 13, 2026, final submissions from interested parties were due by June 2, 2026, and DECOM’s final determination opinion was slated for June 22, 2026, according to the case page maintained by the Ministry of Development, Industry, Trade and Services. GECEX adopted the extension roughly six weeks later, comfortably inside the twelve-month outer limit that Brazilian law allows for sunset reviews.
Eighteen Years of Duties, Suspensions and Reinstatements
The measure’s roots reach back to 2008. The original investigation was closed by CAMEX Resolution No. 51 of August 28, 2008, which imposed definitive anti-dumping duties, collected as ad valorem rates, on suspension PVC from both China and South Korea for a period of up to five years, according to the recitals of subsequent resolutions in the case compiled by the Brazilian legal database LegisWeb.
When that first period neared expiry, the authorities opened a sunset review in late August 2013, the announcement that Global Trade Alert dates to August 29, 2013 in its ledger for intervention 19165. The review concluded with CAMEX Resolution No. 68 of August 14, 2014, published in the gazette on August 15, 2014, which extended the duties on both origins for up to five more years. It is this 2013 to 2014 renewal that GTA tracks as the anchor event for the intervention updated this week.
The 2020 round produced the case’s most turbulent chapter. GECEX Resolution No. 38 of May 4, 2020 first altered the definitive duty. Then, on August 14, 2020, the government issued two acts on the same day in an extra edition of the gazette. SECEX Circular No. 50 closed the review with respect to South Korea without extending the measure, on the ground that there was no demonstrated probability that injury to the domestic industry would recur if the duty on Korean resin were extinguished. GECEX Resolution No. 73, meanwhile, extended the duty on Chinese resin for up to five years but immediately suspended its application, citing doubts about the evolution of imports, according to the ministry’s registry of measures in force and the Chambers and Partners account.
The suspension proved short-lived. The domestic producers sought reconsideration, and GECEX Resolution No. 200 of May 11, 2021 partially granted their request. GECEX Resolution No. 255 of September 24, 2021, published on September 27, 2021, then reapplied the 21.6 percent duty on Chinese PVC-S, restoring the protection that had been extended and frozen a year earlier. From that point the duty ran uninterrupted to its scheduled expiry date of August 14, 2025, and stayed in force by operation of law once the new review opened.
Why South Korea Exited
The Korean termination deserves unpacking, because it explains why the intervention recorded by Global Trade Alert pairs an extension with a termination. Under Article 106 of Decree No. 8.058 of 2013, a sunset review extends a duty only where the evidence shows that dumping and the resulting injury would likely continue or recur without it. For South Korea, SECEX Circular No. 50 of 2020 concluded that this standard was not met: there was no proof of the probability of resumption of injury derived from dumping in Korean exports of PVC-S to Brazil in the event the measure lapsed. The duty on Korean producers was therefore not renewed, and Korean resin has since faced only Brazil’s ordinary import tariff.
The result reflects a commercial reality as much as a legal finding. By the late 2010s Korean suspension PVC had largely receded from the Brazilian market, and Korean vinyls producers had reoriented toward customers closer to home. The termination also foreshadowed a broader shuffling of PVC trade defense across the globe. In July 2026, the Korea Times reported that South Korea itself levied anti-dumping duties on European PVC paste resin, a reminder that the same national industry cleared of injuring Brazil is an active complainant in its home market.
The Petitioners and the Domestic Industry
The renewal is a victory for the two petitioners. Braskem, the largest resin producer in the Americas, operates Brazil’s principal PVC capacity of about 710,000 tonnes per year at units in the states of Bahia and Alagoas, according to the energy and commodities news service Argus Media. Unipar, through its Unipar Indupa subsidiary, operates the country’s other integrated chlor-alkali and vinyls production and has periodically studied expanding its PVC output, as Argus has also reported.
For both companies the duty arrives at a welcome moment. The global petrochemical industry remains mired in a prolonged downcycle of thin margins and surplus capacity, and trade defense has become a central plank of the Brazilian industry’s response. Argus Media reported that Braskem has committed roughly 100 million dollars to expanding and debottlenecking its polyethylene and PVC plants, an investment premised on defending domestic market share, and calculated that Unipar stood to gain about 230 million reais, roughly 40.7 million dollars, in additional Ebitda, an increase of about 18 percent, from the improved pricing dynamics that followed Brazil’s 2025 tightening of PVC trade remedies.
The producers’ case for renewal rested on the argument that the Chinese industry’s sheer scale makes the Brazilian market permanently vulnerable. DECOM’s initiation of the review accepted evidence that, absent the duty, dumping would most likely resume and injury would recur, according to the Chambers and Partners summary of the opening circular. Nothing in the intervening year weakened that premise; if anything, the deterioration of the global PVC balance strengthened it.
Construction Demand and the Import Gap
PVC is, before anything else, a construction material. Pipes, fittings, conduits, window and door profiles, cable insulation, flooring and roofing membranes account for the bulk of demand, which makes the resin a bellwether for Brazil’s building cycle. Domestic consumption has long exceeded the combined output of Braskem and Unipar Indupa, leaving a structural import gap that traders fill from whichever origin offers the lowest landed cost. That arithmetic is precisely what makes anti-dumping rates decisive in this market: they determine which origins are competitive at the margin, and therefore who supplies the tonnes that domestic plants cannot.
The scale of the gap was on display last year. Brazilian imports of the four major thermoplastics, polyethylene, polypropylene, polystyrene and PVC, reached a record 3.32 million tonnes in 2025 despite the country’s expanding lattice of anti-dumping measures, according to an analysis published by the trade analytics platform CZ. The same analysis found that China increased its share of Brazil’s plastics imports to 23.55 percent, while Colombia posted 25 percent growth to reach 9 percent of the total, evidence that trade measures were redirecting flows rather than shrinking them.
The China decision also cannot be read in isolation from Brazil’s treatment of American resin. On May 27, 2025, the foreign trade chamber voted to raise the anti-dumping duty on suspension PVC from the United States to 43.7 percent, up from the 8.2 percent that had applied for years, following a review sought by the domestic producers, as the chemicals intelligence service ICIS reported at the time. Argus Media subsequently reported that the duty increase pushed Brazilian importers toward material from Egypt, Mexico and Taiwan. With American resin now facing 43.7 percent and Chinese resin facing 21.6 percent, the renewal locks in a hierarchy of origins that favors domestic producers first and non-targeted exporters second.
For the construction chain, the cost implications cut the other way. Duties that support domestic resin prices flow through to pipe and profile makers and, ultimately, to the housing and sanitation projects that are heavy consumers of PVC. Brazilian converters have long argued in public interest proceedings that layered trade remedies raise building costs in a country with a large housing deficit and an ambitious basic sanitation agenda. The 2020 suspension of the China duty, justified at the time by doubts over import trends, showed that the government takes those arguments seriously in moments of tight supply. The 2026 renewal shows just as clearly that, in the current global glut, the balance has swung back toward protection.
China’s Overcapacity Shadow
The backdrop to the Brazilian decision is a Chinese PVC industry that produces far more than its home market can absorb. S&P Global Commodity Insights reported in April 2025 that Chinese PVC export prices had fallen to record lows under the combined weight of United States tariffs and Indian import curbs, and that up to 3 million tonnes per year of new PVC capacity was set to come online in China by the end of 2025, lifting total capacity from about 28.7 million to as much as 31.5 million tonnes per year if all the planned projects materialized.
Chinese domestic prices tell the same story. The commodity data provider SunSirs reported that China’s PVC market declined through 2025 on capacity expansion and a persistent supply and demand imbalance, with total capacity ending the year near 29.9 million tonnes, up more than 7 percent from a year earlier. Exports became the safety valve: Chinese PVC powder exports reached about 3.5 million tonnes in the first eleven months of 2025, an increase of 47 percent year on year, according to Chinese customs figures cited in market reports. Separate market commentary has linked the price weakness to the prolonged slump in Chinese property construction, which hollowed out the resin’s largest domestic outlet and left producers chasing overseas buyers.
India, the largest buyer of Chinese PVC, has moved aggressively to shelter its own producers. China shipped 1.33 million tonnes of PVC to India in 2024, about 51 percent of its total exports of the resin, according to S&P Global Commodity Insights. India has since applied provisional anti-dumping duties on suspension PVC from China and several other origins, with rates for Chinese material running from 82 to 167 dollars per tonne, according to reporting by the market research firm Procurement Resource and the chemicals portal Echemi. Every tonne turned away from India must find another home, and Latin America’s open, import-dependent markets are an obvious destination. Brazil’s renewal narrows that channel before it could widen further.
Implications for Traders and Supply Chains
For Chinese exporters, the practical message is that the Brazilian market will remain difficult for another five years. The 21.6 percent anti-dumping duty stacks on top of Brazil’s ordinary import tariff on the product, and Brazilian authorities have shown a growing appetite for policing circumvention, as the indicative-classification language in Resolution No. 947 signals. Traders who contemplate routing Chinese resin through third countries should expect scrutiny, because Brazil maintains an active anti-circumvention practice and has extended duties to transshipped or minimally processed goods in other product lines.
For Brazilian importers and converters, the renewal restores certainty of a costly kind. Purchasing plans can be built around a known duty level rather than the cliff edge of an expiring measure, but the composition of supply will continue to tilt toward origins outside the duty net. Colombia, Egypt, Taiwan and Mexico, among others, gained ground after the 2025 action against American resin and stand to consolidate those gains now that the Chinese duty is fixed for another cycle. Importers retain procedural options, including requests for reconsideration of the kind that reshaped this very measure in 2021, and public interest petitions seeking suspension if domestic supply tightens or prices spike.
For South Korean producers, the confirmed termination means their resin faces no anti-dumping charge in Brazil, a rare open door in a market that has been closing origin by origin. Whether Korean vinyls makers use it is another question. Korean suspension PVC is also among the origins captured by India’s provisional duties, and Korean producers have lately been occupied defending their home market, where imports of European paste resin now face duties of their own, as the Korea Times reported in July 2026. Distance, freight costs and the priority Korean sellers give to nearby Asian customers all suggest the Brazilian opening will be used opportunistically rather than structurally.
The decision also adds a data point to an unmistakable trend in Brazilian trade policy. Brasilia has opened or concluded a steady stream of trade defense proceedings against Chinese goods over the past two years, spanning steel, chemicals, fiber optic cable and consumer products, a wave documented in successive Global Trade Alert entries and summarized by regional outlets such as CELAC News, which reported in July 2026 that Brazil had launched multiple new anti-dumping investigations against China. The PVC-S renewal is among the older measures in that portfolio, but its logic, shielding domestic industry from the overflow of Chinese overcapacity, is the same logic driving the newer cases.
What Comes Next
Resolution No. 947 provides for the duty to run for up to five years, which points to a horizon around August 2031 unless the measure is altered, suspended or revoked in the interim. Interested parties may seek reconsideration of the resolution, as the record of this case amply demonstrates, and any importer or industrial user may petition for a public interest review if market conditions change materially. A further sunset review near the end of the period would be the fourth for this measure, and few observers of Brazilian trade policy would bet against the petitioners filing for it.
For now, the renewal underscores a simple calculus in Brasilia. Brazil operates one of the developing world’s most active trade remedy systems, and its chemical industry, anchored by Braskem and Unipar, has become one of that system’s most effective users. As long as Chinese PVC capacity keeps growing faster than Chinese demand, and as long as other large importers keep raising their own walls, the pressure on open, import-dependent markets like Brazil’s will persist. The duty first imposed in 2008, extended in 2014, terminated for Korea, then suspended, restored and now renewed for China, runs on toward its third decade.
