Brazil PE Resin Import Landed Cost: How the Four-Layer Tax Cascade Actually Works (2026)

Brazil’s PE Import Surge — and Why the Cost Math Matters

Brazil’s appetite for imported polyethylene has grown sharply. According to International Trader Publications, PE imports reached 2.0 million tonnes in 2024, a 40% jump from 2023 levels. That volume surge pushed Braskem’s domestic polymer market share from approximately 60% down to just over 40%, per Argus Media — a significant shift for the company that had long held a near-dominant position in Brazil’s resin supply.

The supply opportunity is real, but two regulatory changes since October 2024 have fundamentally reset the landed-cost arithmetic. A third change — Brazil’s definitive anti-dumping ruling of March 2026 — has locked major import corridors out of the market for five years. Sourcing managers benchmarking against a pre-2024 tariff environment are working with a cost model that no longer reflects today’s rules.

The Four-Layer Tax Cascade: How Each Charge Compounds

Brazil’s import tax stack for PE resin (NCM 3901.x) consists of four distinct charges, applied in a fixed sequence on an expanding base, per NovaTrade Brasil.

II (Import Duty) on CIF value. Gecex raised the II on polyethylene from 12.6% to 20% in October 2024, covering all NCM 3901 subheadings, per Argus Media. This measure was initially approved for 12 months and has since been extended through 2026. On a USD 1,000/mt CIF cargo, II adds USD 200/mt before any other charge is applied.

IPI on CIF + II sub-total. IPI (Imposto sobre Produtos Industrializados) is levied on the combined CIF + II base. Per PwC Tax Summaries, raw industrial polymer inputs can qualify for reduced IPI rates under the TIPI essentiality principle. The specific rate for your NCM sub-heading must be confirmed against the official TIPI table through your licensed customs broker — this figure can vary and is not uniform across all NCM 3901 sub-codes.

PIS/COFINS at 11.75% on CIF value. PIS-Import stands at 2.10% and COFINS-Import at 9.65%, yielding a combined 11.75% on the customs CIF value, per PwC Tax Summaries (Brazil). On a USD 1,000/mt CIF cargo, this adds USD 117.50/mt. Note that PIS/COFINS applies to the CIF value, not the post-II sub-total — it does not compound on the duty amount.

ICMS gross-up (por dentro) on the cumulative sub-total. ICMS is calculated using a por dentro formula. Per NovaTrade Brasil, the order of the full cascade is: (1) II on CIF, (2) IPI on CIF + II, (3) PIS/COFINS on CIF value, (4) ICMS gross-up on the combined sub-total.

ICMS Por Dentro: The Hidden Multiplier Most Buyers Miss

The por dentro methodology is the most misunderstood element of Brazil’s import cost structure. When a sourcing manager simply adds 20% II + 11.75% PIS/COFINS + 18% ICMS, the intuitive sum is approximately 50% above CIF. The actual landed-cost premium for São Paulo delivery lands closer to 60–65% above CIF, because ICMS is applied on a gross-up base that already includes the ICMS amount itself.

Per NovaTrade Brasil, the formula is: ICMS Base = (CIF + II + IPI + PIS/COFINS) ÷ (1 − ICMS rate). At São Paulo’s 18% rate, a nominal 18% ICMS produces an effective burden of approximately 21.95% on the pre-ICMS sub-total. At Rio de Janeiro’s 20% rate, the effective burden rises further.

Working through the math with a USD 1,000/mt CIF price for LLDPE delivered to São Paulo (assuming 0% IPI for simplicity — confirm actual rate):

• After II at 20%: sub-total USD 1,200/mt
• PIS/COFINS at 11.75% on CIF: +USD 117.50/mt → sub-total USD 1,317.50/mt
• ICMS gross-up at 18% SP: base = USD 1,317.50 ÷ (1 − 0.18) ≈ USD 1,606/mt; ICMS = ≈ USD 289/mt
• Approximate total before brokerage and domestic logistics: ≈ USD 1,606/mt

That is a 60.6% premium above the USD 1,000/mt CIF price. Per My Business Brazil, Brazil’s full seven-levy import stack typically adds 40–100% to CIF costs depending on the product category — the PE calculation falls in the lower half of this range but remains far above the 38–45% that was accurate under the pre-October 2024 tariff regime.

Anti-Dumping Duties: How the US and Canada Got Priced Out

Provisional anti-dumping duties on PE resin imports from the USA and Canada were applied in August 2025. Brazil’s trade remedies department (Decom) issued a definitive ruling on March 26, 2026, establishing a five-year term, per Argus Media:

• US-origin PE: USD 199.04 per tonne
• Canada-origin PE: USD 238.49 per tonne

Per Trench Rossi Watanabe, the affected NCM codes are 3901.10.30, 3901.20.29, and 3901.40.00, covering HDPE, LDPE, LLDPE, MLLDPE, and UHMWPE in primary form without fillers. Three sub-codes are excluded — 3901.20.21, 3901.30.10, and 3901.30.90 — making accurate NCM classification critical before placing import orders.

The investigation was initiated on November 14, 2024, by petition from Braskem S.A., Brazil’s sole domestic PE producer during the period analyzed. At a CFR price of USD 950/mt for LLDPE butene, the USD 199/tonne anti-dumping surcharge adds approximately 21% to the CIF base before the domestic tax cascade begins — a cumulative disadvantage of approximately 21% × (1 + 0.60) ≈ 33% in landed cost terms relative to origins not subject to the duty.

Origin Arbitrage: Where Korean and Southeast Asian PE Win

Brazil’s anti-dumping duties apply exclusively to US and Canadian origins. Korean, Southeast Asian, and Middle Eastern PE currently faces only the 20% II and the domestic tax cascade — no additional anti-dumping surcharge. This creates a structural cost gap relative to North American competitors.

Per Syntex America, Southeast Asian LLDPE butene is available at USD 865–895/mt CFR Southeast Asia, with freight to Santos running approximately USD 69–86/mt, yielding an estimated CIF Santos of USD 934–981/mt — with no anti-dumping surcharge. This compares favorably against US-origin LLDPE at similar base prices plus the USD 199/tonne penalty.

Argentina holds an additional structural advantage: Mercosur intra-zone zero II exemption on PE. Argentine-origin material enters Brazil at 0% import duty instead of 20%. Per Argus Media, Argentina’s volume share of Brazil’s PE imports grew to 14.4% (176,375 tonnes) in 2025, up from 10.9% the prior year, driven largely by this tariff differential.

For sourcing managers evaluating Korean PE resin suppliers: the 20% II applies, and the full domestic cascade applies — but the absence of anti-dumping exposure means Korean-origin PE enters Brazil on structurally equal terms with Southeast Asian material and at a significant cost advantage over US and Canadian origins.

Two Tax Reliefs Worth Knowing

Drawback regime. Brazil’s Drawback customs regime suspends II, IPI, PIS-Import, and COFINS-Import on imported PE resin used to manufacture goods for subsequent export, per NovaTrade Brasil. For blown-film converters, PE packaging manufacturers, or pipe extruders that export a significant share of finished product to third markets, Drawback can eliminate most of the four-layer cascade for the export-directed share of production. This is not a universal relief — domestic sales remain fully taxed at the full cascade rate.

Tax reform timeline. Brazil’s constitutional tax reform (Amendment 132/2023 and Complementary Law 214/2025) will gradually replace PIS, COFINS, IPI, ICMS, and ISS with two new value-added taxes — CBS and IBS — between 2026 and 2033, per PwC Tax Summaries. 2026 is the pilot year. The current cascade structure remains fully in force through at least the rest of 2026 and will wind down progressively through 2033. Purchasing decisions made in 2026 should assume the full cascade applies for at least the next 12–24 months.
