Epichlorohydrin Import Duty & HS Code Guide: 2910.30 Across EU, ASEAN and China defines the customs classification and tariff treatment of epichlorohydrin (ECH, CAS 106-89-8, EC 203-439-8), chemically identified as 1-chloro-2,3-epoxypropane. Under the WCO Harmonized System the substance is classified in heading 2910, subheading 2910.30. The heading covers epoxides, epoxyalcohols, epoxyethers and their halogenated derivatives; subheading 2910.30 specifically captures 1-chloro-2,3-epoxypropane when the imported material is a chemically pure compound. The molecular formula is C₃H₅ClO and the molecular mass is 92.52 g/mol. Import duty exposure therefore turns on the six-digit HS classification, the national subdivision, the declared origin, and the proof of preference available at clearance.

Under General Interpretative Rule 1 and General Interpretative Rule 6, classification is determined first by the heading text and the Notes to Section VI and Chapter 29, then by the subheading text at the six-digit level. A product that is a mixture, a formulated preparation, or a cured epoxy system containing epichlorohydrin as a residue does not remain in 2910.30; it may fall under heading 3824 or a polymer-related heading if the mixture has a distinct function. The national schedules of the EU, ASEAN member states, and China each extend 2910.30 to eight digits or longer, but the six-digit WCO subheading remains the anchor for tariff binding and advance rulings. Every commercial invoice and packing list should therefore describe the material as epichlorohydrin and not merely as an epoxide or chlorinated ether.

When does EU TARIC code 2910 30 00 apply to a commercial import?

Within the European Union, the operative Combined Nomenclature code is 2910 30 00. The erga omnes third-country duty rate for this subheading is 5.5% of the customs value. If the shipment is accompanied by a valid proof of preferential origin under a free trade agreement or the Generalised Scheme of Preferences, the duty may be reduced or suspended to 0%. Preferential entry for ECH is documented through the REX system for GSP beneficiaries, or through EUR.1 or an origin declaration by an approved exporter under EU bilateral agreements. The importer must enter the preference against the correct TARIC measure at declaration; failure to select the preference on the import declaration can result in the full 5.5% rate being charged even where origin evidence exists.

The import VAT for ECH is levied by the member state on the customs value plus the customs duty. Member-state standard VAT rates are not harmonised; they range from 17% to 27%. In a member state applying a standard rate of 21%, a commercial import with 5.5% duty carries a combined VAT-inclusive customs burden of approximately 27.7% of the CIF value before port, agency, and storage charges. The importer may recover the import VAT in a subsequent commercial transaction if it is a registered taxable person, but the clearance event itself creates an immediate cash-flow burden. Customs duty is not recoverable as VAT input tax. The same VAT treatment applies whether the goods are imported in bulk chemical tankers, ISO tank containers, or steel drums.

Under the ASEAN Harmonized Tariff Nomenclature 2022, the subheading 2910.30.00 is aligned with the WCO six-digit code. ASEAN is not a customs union, so the extra-ASEAN MFN duty is set individually by each member state. For this subheading, published MFN rates in the major ASEAN importing countries commonly fall between 0% and 5%, as published in the national customs tariff schedules; the effective rate for a specific entry must be confirmed against the schedule in force because some member states update rates outside the AHTN cycle. Intra-ASEAN trade under the ASEAN Trade in Goods Agreement can receive a 0% preferential rate when the goods meet origin requirements. The standard origin test for ECH under ATIGA is either a regional value content threshold of not less than 40% or a change in tariff classification as set out in the product-specific rules. Form D is the controlling proof of origin for the ATIGA rate.

Customs audits of chemical shipments in the region frequently focus on the RVC calculation rather than the HS code because the six-digit classification is usually not in dispute. A manufacturer deriving ECH from glycerol or propylene feedstocks must be prepared to present a bill of materials, feedstock invoices, and utility cost allocations that support the 40% regional value content. If the importer cannot produce a valid Form D or the underlying cost data, the full MFN rate applies. For extra-ASEAN shipments, a common practical failure is submitting an AHTN code without the importing member state’s current seven- or eight-digit extension; the declaration must use the national code in force at the date of entry. Where a member state publishes a separate statistical suffix, the full suffix must be declared to avoid electronic rejection.

China’s MFN rate, VAT and trade remedy overlay

Importation into the People’s Republic of China uses the eight-digit customs commodity code 2910.30.00 in the annual Customs Import and Export Tariff. The MFN import duty for epichlorohydrin is 5.5%. Import VAT is assessed at 13% on the sum of the customs value, the import duty, and any applicable trade remedy duty. Without an anti-dumping measure, the combined MFN-plus-VAT burden on the CIF value is approximately 19.2% before customs brokerage, port, inspection, and quarantine charges. If the imported product originates in a jurisdiction covered by a current anti-dumping order, the company-specific margin is added before VAT is computed. Published PRC trade remedy measures for ECH have covered specified producers in Japan, the Republic of Korea and Russia; the margin is company-specific and is applied in addition to the MFN duty.

The VAT component is recoverable for VAT general taxpayers after importation, but the initial import declaration must include the full VAT amount. In the customs declaration system, the import VAT is calculated by the General Administration of Customs on the basis of the dutiable value plus all duties. Anti-dumping duty is therefore not merely a small additive; because it enters the VAT base, a higher anti-dumping margin magnifies the total cash payment at the port. For a CIF value of USD 100,000 and an MFN rate of 5.5%, customs duty equals USD 5,500. If a company-specific anti-dumping margin of 15% applied for illustration, the anti-dumping duty would be USD 15,000, and the 13% VAT would be assessed on USD 120,500, yielding VAT of USD 15,665. The total statutory payment would be USD 36,165 before port charges. These values are illustrative; the actual margin must be taken from the current PRC trade remedy schedule, and the exact payment is calculated in the customs declaration system.

Customs documentation for ECH is not a single-line entry. The importer must reconcile the commercial invoice, certificate of origin, safety data sheet, packing list, and tariff declaration. The following matrix aligns the national code, baseline duty, preferential proof, and origin anchor that control release.

For a preferential claim in any regional FTA, the proof of origin controls the rate more than the tariff code itself. Under the ASEAN-China Free Trade Area, Form E can reduce the Chinese import duty on ECH from 5.5% to 0% for an originating shipment. Under ATIGA, Form D supports a 0% intra-ASEAN rate. Under the EU GSP, the REX registration replaces Form A and must be present on the customs declaration. Under the Regional Comprehensive Economic Partnership, a Proof of Origin or an approved exporter declaration may be used where the goods satisfy RCEP product-specific rules. Third-party invoicing must be checked against the certificate fields; a mismatch between the invoice number, the manufacturer, and the certificate reference is a recurring reason for rejecting preferential treatment. Customs authorities may also verify the origin data after release, and a post-clearance demand for duty difference can arise several months after the goods have been cleared.

Non-preferential origin remains relevant when no preference is claimed. The EU applies non-preferential origin rules under Article 60 of the Union Customs Code, not the Harmonized System. For a multistage chemical operation in which ECH is purified or repacked in an intermediate country, the last substantial transformation standard determines the origin for trade remedy and MFN purposes. If the only operation is dilution or packaging, origin will not change. In China, non-preferential origin is determined under the Regulations on the Origin of Imported and Exported Goods; importers of ECH subject to anti-dumping orders must retain production records that support origin. A certificate of origin issued for one purpose is not automatically valid for another preference or trade remedy purpose.

If the loading country or exporter is subject to a trade defence measure, the clearance arithmetic changes

Where the commercial invoice names a producer or exporter subject to an anti-dumping or countervailing duty order, the entry is charged at an order-specific composite rate rather than the standard MFN rate. The sequence of assessment is similar in the EU and China: the anti-dumping duty is added to the customs value, and import VAT is then calculated on the duty-inclusive amount. An EU importer entering ECH under a 5.5% conventional duty and a definitive anti-dumping duty would face the same sequencing. The declaration of origin, supplier declaration, and commercial invoice must be consistent with the country of production; if the goods are shipped through a third country, the documentary trail must show that the origin did not change in transit. A mere transshipment or temporary storage does not create a new origin, but it may obscure the documentary trail if the bills of lading and invoices are not aligned.

This is where customs brokers and importers most frequently encounter post-clearance demands. A declaration that claims preference but fails the RVC audit, or a trade remedy declaration that omits an exporter-specific code, triggers a post-clearance assessment as well as potential penalty interest. For bulk ECH imported in ISO tanks or chemical tankers, the customs entry must reflect the actual net quantity in the tariff line; quantity-based thresholds are not relevant to the ad valorem duty in 2910.30, but absolute VAT and duty amounts scale directly with the declared customs value. The importer’s invoice and transfer pricing documentation should therefore match the CIF value line item for line item. If a related-party transfer price is used, the customs authority may examine whether the declared value reflects the arm’s length standard; an uplift in customs value will increase both duty and VAT.

Parties encountering disagreement over the national eight-digit subdivision may request a Binding Tariff Information in the EU under Article 33 of the Union Customs Code, a customs advance ruling in China under the current GAC advance ruling rules, or the equivalent advance ruling mechanism in the relevant ASEAN member state. Such rulings are binding only for the applicant and only for the described product. For ECH, disputes rarely concern the six-digit subheading 2910.30; they more commonly concern whether a stabiliser or moisture level changes heading 2910 classification or whether a sample is a mixture under Chapter 29 Note 1. A written ruling is therefore a control instrument for importers whose supply chain crosses multiple national tariff schedules.

ECH is also a dangerous goods entry. The transport classification under UN 2023 affects container packing and safety documentation rather than the customs tariff, but incorrect UN identification can delay clearance and create a discrepancy with the customs declaration. The SDS must align with the invoice description “epichlorohydrin” and the HS code 2910.30; if the SDS lists a mixture trade name, the customs description should carry the same chemical identity to avoid a classification query. Importers in the EU and China must ensure that the SDS matches the entry and that any mandatory registration or notification obligation is discharged; these are non-tariff obligations separate from duty payment.
