The World Customs Organization has formally adopted the next edition of the Harmonized System. HS 2028 enters into force on January 1, 2028, bringing 299 sets of changes to the classification framework that underpins every customs declaration, duty calculation, and free trade agreement eligibility determination made by over 200 economies worldwide. For HS 2028 importers, the transition date is not the preparation date. The WCO confirmed a two-year implementation window from acceptance of amendments, which means the work of updating classification databases, reviewing FTA eligibility, and assessing duty rate changes needs to happen in 2026 and 2027, not after January 2028. This guide covers what HS 2028 changes, which product categories are most affected, why classification errors after the transition date carry serious financial and compliance consequences, and the four steps every importer should take before the deadline.
What Is HS 2028 and Why It Was Delayed From 2027
The Harmonized System is the international standard for classifying traded goods, maintained by the World Customs Organization and used by over 200 countries as the basis for customs tariffs, trade statistics, rules of origin determinations, and free trade agreement eligibility assessments. The WCO updates the HS on a five-year cycle. The previous update, HS 2022, entered into force on January 1, 2022. The next update was originally planned as HS 2027, but the WCO extended the revision cycle by one year due to delays caused by the COVID-19 pandemic. The result is HS 2028, the eighth edition of the Harmonized System since the Convention entered into force in 1988.
The formal adoption timeline for HS 2028 was as follows:
- March 2025: WCO Harmonized System Committee completed six years of technical work and provisionally adopted the HS 2028 amendments at its 75th session
- June 2025: WCO Council formally adopted the amendments as an Article 16 Recommendation
- December 2025: Formal adoption of all HS 2028 amendments confirmed by Contracting Parties
- January 2026: Official HS 2028 nomenclature published by WCO. Full text of all 299 sets of changes now available to importers, customs brokers, and trade compliance teams
- January 1, 2028: HS 2028 enters into force globally across all 200+ member economies
Full details of all amendments are published on the WCO official HS 2028 amendments page, which is the authoritative source for all classification changes.
The Scale of HS 2028 Changes: What the Numbers Mean for Importers
The scale of the HS 2028 update is significant. Compared to the HS 2022 edition, the changes produce a materially different nomenclature structure:
| Metric | HS 2022 | HS 2028 | Change |
|---|---|---|---|
| Total amendment sets | 351 | 299 | Fewer but more structurally significant |
| Total headings | 1,228 | 1,229 | +1 net new heading |
| Total subheadings | 5,612 | 5,852 | +240 net new subheadings |
| New subheadings created | N/A | 428 | New product categories requiring reclassification |
| Subheadings deleted | N/A | 172 | Products previously classified here need new codes |
For HS 2028 importers, the practical implication of 428 new subheadings and 172 deleted ones is that a significant proportion of the products they currently declare under existing codes will need to be reclassified before January 1, 2028. Products declared under deleted subheadings after that date will generate classification errors in customs systems. Products that should move to new, more specific subheadings but remain under the old broader heading may face incorrect duty rates, missed FTA preferential eligibility, or customs authority challenges on audit.
HS 2028 Classification Changes: Which Product Categories Are Most Affected
Electronics and Semiconductors
New subheadings for chips and integrated circuits address the rapid evolution of semiconductor technology since HS 2022 was adopted. For importers of advanced computing hardware, AI accelerators, and telecommunications equipment, the HS 2028 classification changes in this sector are directly relevant to the duty rates and export control classifications applied to their goods. Importers currently declaring semiconductors and advanced chips under broad HS 2022 headings should review their specific product descriptions against the new HS 2028 subheadings to identify whether reclassification produces a different duty rate or changes their FTA eligibility in destination markets. This is particularly relevant for businesses importing into the US, the EU, and UK where semiconductor classification intersects with both duty rates and export control screening obligations.
Vaccines and Pharmaceuticals
HS 2028 introduces major structural changes to pharmaceutical classification. Vaccines previously classified under heading 30.02 are reclassified into two new headings: heading 30.07 for vaccines for human medicine with disease-based subheadings, and heading 30.08 for other vaccines including veterinary vaccines. Additionally, 441 names for pharmaceutical substances from the WHO International Nonproprietary Names programme have been incorporated into the HS 2028 nomenclature, replacing the current residual classification approach for many substances. A new heading 21.07 for dietary supplements resolves long-standing classification challenges at the boundary between foodstuffs and pharmaceutical products. Importers of vaccines, pharmaceuticals, nutraceuticals, and dietary supplements will need to reclassify affected products and reassess the import licensing, regulatory approval, and FTA eligibility implications of their new classifications in each destination market.
Green Technology and Energy Products
The HS 2028 update reflects the significant growth in green technology trade since HS 2022. New and revised codes cover photovoltaic wafers and solar technology components, hydrogen fuel cells and hydrogen production equipment, and updated classifications for lithium compounds used in battery manufacturing. For importers and exporters in the solar, battery storage, hydrogen energy, and electric vehicle sectors, HS 2028 classification changes affect duty rates, FTA eligibility, and the statistical reporting obligations that underpin trade policy decisions in this sector. The EU’s CBAM mechanism, which already applies carbon pricing to certain industrial imports, operates alongside HS classification and any reclassification of covered goods warrants a parallel CBAM compliance review.
Plastic Waste and Environmental Products
The plastic waste classification section has been restructured to align more closely with the categories of the Basel Convention, distinguishing more precisely between hazardous waste, PIC-controlled plastic waste, and other plastic residues. Single-use plastics are explicitly addressed in the new structure. For businesses involved in waste trade, recycling supply chains, or the import of secondary raw materials, the HS 2028 reclassification of plastic waste categories may affect the permits, licences, and import authorisations required in destination countries, not just the duty rate.
Public Health and Medical Equipment
New subheadings in HS 2028 improve the classification visibility of critical health emergency supplies including ambulances, personal protective equipment, ventilators, and diagnostic devices. These changes reflect lessons from the COVID-19 pandemic, where the absence of specific subheadings for these products complicated customs processing, trade statistics, and preferential tariff treatment during supply emergencies. Importers of medical devices and healthcare equipment into India, Saudi Arabia, the UAE, and other markets with product-specific import licensing requirements should review the HS 2028 medical equipment changes against their current import authorisation portfolios.
Why HS 2028 Is Not Just a Classification Exercise
Most importers think of HS code changes as an administrative update. Change the code in the system, retrain the team, update the documentation. The commercial reality is more significant. HS 2028 classification changes carry four types of financial and compliance consequences that go beyond the code itself:
- Duty rates change when headings change: A product that moves from a broadly defined heading to a new, specific HS 2028 subheading may attract a materially different duty rate in the destination country. That change can be positive (lower rate under the new specific code) or negative (higher rate if the new subheading carries a different tariff treatment). Neither outcome is automatic. It requires active classification work to identify and document
- FTA eligibility changes: Free trade agreements reference specific HS codes to define which goods qualify for preferential rates. When a product’s HS code changes under HS 2028, its eligibility under any active FTA must be re-evaluated under the new code. A product that qualified for zero duty under a bilateral FTA at its HS 2022 code may or may not qualify at its new HS 2028 code depending on how that FTA’s preferential schedule is transposed to the new nomenclature
- Origin rules change: Rules of origin in FTAs are often expressed in terms of specific HS headings or subheadings. When those headings change under HS 2028, the applicable transformation rule for origin qualification may change as well. Importers and manufacturers that have structured their supply chains to meet a specific origin rule based on HS 2022 codes need to verify that the same structure meets the origin rule under HS 2028
- Licensing and permit requirements change: Import licences, product certifications, and regulatory approvals are often linked to specific HS headings. When a product moves to a new heading under HS 2028, the applicable licensing regime in the destination country may change. This is particularly relevant for medical devices, pharmaceuticals, dual-use goods, and hazardous materials, where the regulatory framework tracks the HS classification
Why 2026 Is the Year to Act on HS 2028 Compliance, Not 2027
The most common planning error importers make on HS updates is treating the entry into force date as the preparation deadline. It is not. January 1, 2028 is the date by which all preparation must be completed. The preparation itself takes time that most importers significantly underestimate.
The WCO confirmed a two-year implementation period from acceptance of amendments, during which correlation tables between HS 2022 and HS 2028 are being developed, national tariff schedules are being updated, and member economies are adapting their sovereign classification systems including the EU Combined Nomenclature and the UK Global Tariff. Those correlation tables, which map each current HS 2022 code to its HS 2028 equivalent, will be published by the WCO during 2026 and 2027. They are the practical tool that classification teams use to identify which products need to be reclassified and what their new codes are. Waiting for the correlation tables to be finalised before starting preparation is waiting too long. For an importer with hundreds of product lines, a complete classification audit takes months. For a manufacturer with a complex product catalogue spanning multiple sectors, it can take longer. Starting in late 2027 leaves no time for the validation, ERP system updates, documentation changes, and supplier communication that a clean HS 2028 transition requires.
Four Steps Every HS 2028 Importer Must Take Before January 2028
- Run a full classification audit against your active import entries now. Pull every HS code currently declared across all your active import corridors. Cross-reference each code against the WCO published HS 2028 amendments to identify which headings and subheadings are being created, modified, or deleted. Products currently classified under subheadings that HS 2028 deletes need to be reclassified before January 2028. Products in sectors with significant HS 2028 changes, particularly electronics, pharmaceuticals, green tech, and medical equipment, should be prioritised. Our Global Trade Compliance team conducts HS 2028 classification audits across active import portfolios in all major markets
- Review FTA eligibility under the new HS 2028 codes. For every product that changes code under HS 2028, assess whether the new code maintains, gains, or loses eligibility under any active FTA covering your import corridors. This includes RCEP, CPTPP, EUSFTA, USSFTA, ChAFTA, KAFTA, and any bilateral FTA in your active sourcing network. FTA eligibility changes that are not identified before the transition date produce incorrect preferential claims or missed duty savings from the moment HS 2028 takes effect
- Update your ERP, trade management systems, and customs documentation templates. HS codes are embedded throughout import operations: in purchase orders, commercial invoices, packing lists, customs declarations, Letters of Credit, and regulatory submissions. Every system and template that contains an HS code needs to be updated before January 1, 2028. This is a data management project, not just a compliance project. Systems that have not been updated will generate incorrect declarations from day one of the new nomenclature
- Communicate the changes to your suppliers and logistics partners. Suppliers producing commercial invoices with HS codes, freight forwarders filing declarations, and customs brokers classifying goods all need to be operating on HS 2028 from January 1, 2028. A clean transition requires coordinated preparation across the supply chain, not just within your own organisation. Brief your key suppliers on which product categories are affected by HS 2028 changes in your bilateral trade corridors

Frequently Asked Questions: HS 2028 Importers
What is HS 2028 and when does it take effect?
HS 2028 is the eighth edition of the Harmonized System maintained by the World Customs Organization. It was formally adopted in December 2025 and published in January 2026. It enters into force on January 1, 2028 across all 200+ WCO member economies. It comprises 299 sets of changes to the HS 2022 nomenclature, creating 428 new subheadings and deleting 172 existing ones. It was originally planned as HS 2027 but was delayed by one year due to COVID-19 impacts on the WCO revision process.
Which industries face the biggest HS 2028 classification changes?
The sectors with the most significant HS 2028 classification changes are electronics and semiconductors, vaccines and pharmaceuticals, green technology including solar, hydrogen, and battery products, plastic waste and recycled materials, and public health and medical equipment. Importers in any of these sectors should treat HS 2028 classification review as an immediate priority rather than a 2027 task.
Does HS 2028 affect my FTA preferential duty rates?
Yes, potentially. FTAs reference specific HS codes to define preferential eligibility. When a product’s HS code changes under HS 2028, its eligibility under any active FTA must be reassessed at the new code. Some products will maintain their preferential status. Others may gain new eligibility under more specific subheadings. Some may lose eligibility if the new heading carries different treatment in the FTA schedule. This FTA eligibility review is one of the most commercially significant aspects of HS 2028 preparation and one of the most commonly overlooked.
What happens if I continue using HS 2022 codes after January 1, 2028?
Customs declarations filed with superseded HS 2022 codes after January 1, 2028 will generate classification errors in customs authority systems. For subheadings that have been deleted entirely, the code will not be recognised as valid. For subheadings that have been restructured or merged, the old code may still technically process but will produce incorrect duty rate calculations, incorrect FTA eligibility determinations, and audit exposure tied to a product database that no longer reflects current regulatory structure. The financial risk includes overpaid or underpaid duty, invalid FTA claims, and potential penalties for systematic misclassification.
When will the HS 2022 to HS 2028 correlation tables be published?
The WCO develops correlation tables during the two-year implementation period following formal adoption of amendments. The tables map each HS 2022 code to its HS 2028 equivalent and are the primary tool classification teams use to identify which products need reclassification. Full publication is expected during 2026 and into 2027 as the WCO and member economies complete their transposition work. Importers should not wait for the full correlation tables before beginning their own classification review. Starting with the known high-impact sectors, particularly electronics, pharmaceuticals, and green technology, allows preparatory work to begin immediately on the most commercially significant changes.
Does HS 2028 affect import licensing and regulatory approvals?
Yes for certain product categories. Import licences, product certifications, and regulatory approvals in many markets are linked to specific HS headings. When a product moves to a new heading under HS 2028, the applicable licensing or approval regime may change. This is most relevant for medical devices, pharmaceuticals, dual-use goods, and hazardous materials. Businesses importing these categories should include a licensing and permit review as part of their HS 2028 classification audit, particularly for imports into markets with product-specific import authorisation requirements such as India, Saudi Arabia, the UAE, China, and Brazil.
