Brazil Imposes Provisional Anti-Dumping Duties on Glass-Fibre Rovings from China

What did Brazil decide on 4 September 2026?

Brazil has imposed provisional anti-dumping duties on certain glass-fibre rovings originating in China and Egypt from 4 September 2026. Brazil’s foreign trade committee, GECEX, published the measure, which the Brazilian authorities state will apply for no more than six months, until 4 March 2027.

A provisional anti-dumping duty is a time-limited trade measure applied while a proceeding is still provisional or has not yet reached its final stage. For an importer, “provisional” does not mean that the goods are automatically free of additional duties or that the measure can be ignored. The applicable Brazilian customs treatment, including any required security or collection procedure, must be checked against the current Brazilian rules and the import documents.

The measure does not cover every glass-fibre product or every shipment from China. The decisive factors are the technical product description, the Brazilian NCM code, the origin, and the specific Chinese producer or exporter.

Which products are covered?

The covered products are E-glass and/or E-CR glass fibres in the form of lightly twisted rovings with a linear density of at least 100 g/km. Brazil identifies the relevant product under NCM code 7019.12.90.

A roving in this context is a bundle of glass-fibre filaments that is lightly twisted. Linear density describes the mass assigned to a defined fibre length; the measure specifies a threshold of at least 100 g/km. E-glass and E-CR glass are the glass-fibre types named in the Brazilian product description. These details are not merely commercial labels: together with the tariff classification, they form the core of the scope review.

The NCM code is Brazil’s goods classification code. Matching NCM 7019.12.90 is an important screening point, but it does not replace a technical review of the goods. An importer should therefore not conclude that a product is covered or excluded solely from a supplier’s generic description such as “fiberglass”.

Which product details should be documented?

Before signing a contract, compare at least the following information with the Brazilian measure:

Review point	Description in the Brazilian measure	Practical relevance
Fibre type	E-glass and/or E-CR glass fibre	The material description must match the actual goods and documents.
Product form	Lightly twisted rovings	The filament bundle and product form must be technically identified.
Linear density	At least 100 g/km	This is a specific threshold used for the product scope.
Brazilian code	NCM 7019.12.90	The code must correspond to the planned Brazilian import.
Origin	China or Egypt	The measure refers to these two countries of origin.
Producer or exporter	Producer-specific Chinese rates	The actual supplier may affect the applicable rate.

This table is a working review framework, not a binding customs ruling. If the technical documents conflict, do not carry forward an old NCM classification without a new review.

How high are the provisional rates for China?

The provisional rates for Chinese producers and exporters range from US$211.78 to US$456.44 per tonne. The amount depends on the company allocation stated in the Brazilian measure.

Brazil lists a rate of US$456.44 per tonne for Jushi Group and related companies. Several Taishan Fiberglass companies are listed at US$211.78 per tonne. These two figures must not be treated as one uniform rate for every Chinese supplier.

Company allocation	Stated provisional rate
Jushi Group and related companies	US$456.44 per tonne
Several Taishan Fiberglass companies	US$211.78 per tonne
Chinese producers and exporters overall	US$211.78–456.44 per tonne

The amounts are stated per tonne. For an internal cost review, the covered quantity must therefore be converted into tonnes. A calculation using a specific shipment quantity would require that quantity and would still not establish the complete Brazilian import cost. Freight, insurance, other duties and contractual charges are not described in the supplied measure and must not be inferred from the stated anti-dumping rates.

Does the measure also apply to imports into the EU or the United States?

No. The described measure applies to imports into Brazil and does not automatically apply in the European Union or the United States. The same Chinese product may therefore face different trade-remedy treatment depending on its destination market.

This geographical distinction matters for traders serving several markets. A contract for Brazil should not be priced solely by using a calculation prepared for delivery to the EU or the United States. A Brazilian NCM code should also not be transferred to another customs territory without a separate classification review.

The supplied information does not establish a separate EU or US measure. It also does not establish that every product from the same Chinese producer is subject to an anti-dumping duty in another country. Such a conclusion would go beyond the available evidence.

What should importers check before signing a contract?

Importers serving Brazil should document the goods first, then the NCM code, origin and finally the exact producer or exporter rate. This order helps prevent the use of a lower rate for goods that do not match the technical scope or for a supplier that belongs to a different company allocation.

A six-step review process

1. Request the technical specification: Obtain confirmation of whether the product is E-glass and/or E-CR glass fibre, whether it is supplied as a lightly twisted roving and what linear density is stated.
2. Check the threshold: Verify whether the linear density is at least 100 g/km. A commercial product name without a specification does not establish this point.
3. Secure the goods description: Keep the filament form, twist, glass-fibre type and linear density consistent across purchasing and customs records.
4. Review the NCM code: Compare the goods with Brazilian NCM code 7019.12.90. Do not reuse a previous classification without checking the actual product again.
5. Establish origin: Determine whether the planned Brazilian shipment has China or Egypt as its relevant origin. The measure names both countries.
6. Identify the company precisely: Compare the complete Chinese producer name and, where relevant, related companies with Brazil’s company allocation. A brand name or intermediary name is not sufficient to determine the producer-specific rate.

This process does not replace a binding decision by Brazilian customs or trade authorities. It organizes the documents an importer should bring together before approving the price, placing the order and reviewing the import entry.

What are the contract and costing implications?

The provisional duty should be treated as a potential additional cost in the Brazil calculation once the goods fall within the described scope and the relevant origin and producer allocation have been established. A calculation that omits this review may understate the landed cost.

The contract should identify the technical specification and the intended Brazilian NCM code clearly. The importer should also record which entity actually produces the goods and whether that entity falls within one of the company groups named in the measure. This matters because the stated Chinese rates are not uniform.

Three limitations must be kept in mind when reviewing the contract:

• The supplied information gives provisional rates per tonne, but not a complete formula for calculating the individual import charge.
• It confirms the product scope and NCM code, but not a binding classification for every technically similar product.
• The measure is limited to a maximum of six months; this does not by itself determine how a shipment will be treated if it is imported or cleared close to 4 March 2027.

These points should be checked with the relevant Brazilian authorities, the customs representative and the importer’s own documents before a binding price commitment is made. The supplied sources do not provide further detail on individual customs clearance treatment.

What is certain until 4 March 2027, and what remains open?

The available evidence establishes the start date of 4 September 2026, the product scope, NCM code 7019.12.90, the countries of origin China and Egypt, the Chinese rate range of US$211.78 to US$456.44 per tonne, and the Brazilian statement that the provisional measure runs until 4 March 2027.

On the supplied information, it remains open whether a definitive measure will follow and in what form. The sources do not establish an extension, a withdrawal or a definitive rate beyond the stated provisional period. Importers should therefore monitor the end date and should not assume either that the provisional rates will continue unchanged or that they will automatically disappear.

For an individual shipment, the technical product scope, actual origin and correct company allocation remain decisive. An invoice showing a Chinese supplier name does not automatically answer which producer allocation determines the rate.

Which documents should be assembled for each Brazil shipment?

A complete shipment file should bring together the technical product description, linear-density information, glass type, lightly twisted-roving description, intended NCM code, origin and producer identity. These documents should describe the same goods consistently so that purchasing, the customs representative and the internal cost calculation work from one product record.

In practice, the importer should approve one specification before ordering and review any change in producer or product variant. A change of producer, company group or technical configuration can affect the assessment. The supplied sources do not state a de minimis threshold or a general exemption for small quantities, so neither should be assumed.

Conclusion for importers

Brazil’s measure applies from 4 September 2026 to a defined but technically specific range of glass-fibre rovings originating in China and Egypt. For Chinese producers, Brazil lists provisional rates from US$211.78 to US$456.44 per tonne.

For traders serving Brazil, the central task is not to apply a generic rate but to verify the actual goods and the actual producer. Before signing a contract, check E-glass or E-CR glass fibre, the lightly twisted roving form, at least 100 g/km, NCM 7019.12.90, origin and company allocation. The measure does not automatically apply in the EU or the United States.
