EU customs reform: Understanding H1, H6, and H7 declaration types for low-value ecommerce shipments

• The €3 duty applies per item based on tariff classification — not per parcel or physical unit. How goods are grouped onto declaration lines depends on the classification level required by the declaration type your carrier or broker uses, which means the total duty can vary for the same shipment.
• H1, H6, and H7 produce different outcomes. H7 allows the broadest grouping (6-digit HS level), H6 groups at the 8-digit CN level for postal shipments, and H1 requires the most detail (10-digit TARIC) — meaning more potential declaration lines, and in most cases a higher total duty. The exception is preferential-origin goods, where H1 may be the lowest-cost path.
• Data quality is now a commercial issue, not just a compliance one. Accurate HS codes, product descriptions, and country-of-origin data affect how goods are grouped at customs — which directly impacts the landed cost your customers see.

H1, H6, and H7 are different EU customs declaration types that determine how much classification detail is required and whether items can be grouped together on a single declaration. That distinction matters because the new €3 duty applies per item, where an “item” is defined by tariff classification — not physical quantity. A package of five identical T-shirts is one item (€3); a T-shirt and a watch in the same parcel are two items (€6). In filing terms, this means the duty is assessed per customs declaration line, and how goods are grouped onto those lines — which depends on the declaration type used — determines the total amount owed.

H1: Standard customs declaration

H1 is the standard declaration type and demands the most granular classification. Products must be classified at the full 10-digit Integrated Tariff of the European Communities (TARIC) level, which is more specific than the 6-digit HS or 8-digit CN codes used in H7 and H6 declarations, respectively. Because items can only be grouped when they match at this detailed level, H1 declarations tend to produce more declaration lines when products differ at the TARIC level. It is typically used where a carrier, broker, or declarant files a full customs declaration, or where a specific customs treatment requires the standard declaration path.

There’s one important exception to the general rule that H1 produces a higher duty outcome. Goods that qualify for preferential treatment under an EU trade agreement — such as the EU-UK Trade and Cooperation Agreement — may be eligible for a zero-duty rate when declared under H1, provided proof of origin is supplied and VAT was not collected via IOSS. In these cases, H1 is not the most expensive path: it is the only declaration type through which preferential origin treatment can be claimed, making it potentially the lowest-cost option for qualifying shipments.

H6: Postal declaration

H6 applies to postal consignments and allows products to be grouped at the 8-digit CN level rather than the full 10-digit TARIC level. That broader grouping means multiple goods sharing the same 8-digit classification can be consolidated onto fewer declaration lines, which can reduce the total duty owed. H6 is the relevant declaration type for sellers using postal operators or postal clearance flows.

H7: Courier or low-value consignment declaration

H7 is typically used for low-value consignments handled by couriers or other declarants and offers the broadest grouping of the three types — at the 6-digit HS level. Where multiple goods share the same 6-digit HS classification, they may be consolidated onto a single declaration line, potentially resulting in the fewest lines and the lowest duty outcome. H7 applies to courier-style low-value shipment workflows where the carrier or declarant files using the H7 process.

The European Commission defines the €3 duty as applying per item, where “item” means a distinct tariff classification — not a physical unit. A package of five identical T-shirts counts as one item; a T-shirt and a watch count as two. In filing terms, this maps directly to customs declaration lines: each line represents one item as defined by tariff classification, and a line may cover multiple physical units if they share the same classification. Because the declaration type (H1, H6, or H7) determines how granularly goods are classified and grouped onto lines, the same parcel can produce a different number of lines — and a different total duty — depending on which declaration type is used. To be precise: the duty rule itself is uniform across H1, H6, and H7 — what varies is how many separate tariff lines a shipment is split into, because each declaration type requires a different level of classification detail.

Example: Three apparel items in one parcel

Assume a shipment contains a red cotton T-shirt, a blue cotton T-shirt, and a polyester T-shirt.

• Under H1, if the goods differ at the 10-digit TARIC level, they may need to be declared on separate lines. That could result in multiple €3 charges.
• Under H6, postal consignments can group at the 8-digit CN level. If the items match at the 8-digit level, they may be consolidated onto fewer declaration lines.
• Under H7, courier or low-value declaration flows can group at the 6-digit HS level. If the products share the same 6-digit HS code, they may be grouped more broadly.
   

The carrier or broker’s actual declaration type must match the clearance type used in your duties or landed cost calculation service setup. Otherwise, the amount collected from the customer may not match the amount assessed at customs.

Does your clearance model guarantee the reduced €3 calculation?

Not necessarily. Aligning your duty calculation to an intended clearance model — whether H1, H6, or H7 — helps you estimate the likely cost, but it does not by itself guarantee the final amount collected at the border. What matters is whether your carrier or customs broker actually files the declaration the way you assumed.

That means businesses need to have direct conversations with their logistics partners before shipments begin. Specifically, you should confirm which declaration type will be used at the border, whether items will be grouped or split on the declaration, what classification level is applied for grouping, and whether product description, country of origin, or other data could affect that grouping. It is also worth checking whether any product types or shipment categories are excluded from simplified treatment altogether.

This alignment is especially important now because the EU reform places significantly greater reliance on accurate electronic shipment data. Depending on your operating model, you may need to supply precise product descriptions, classification codes, consignee details, seller and buyer information, and product identifiers as part of the evolving customs-data requirements — all of which can influence how goods are grouped and what duty is ultimately assessed.

For ecommerce sellers and marketplaces, the declaration type affects more than compliance. It can influence the landed cost shown at checkout.

If a business calculates duties assuming H7 grouping but the carrier files the shipment under H1, the business may undercollect from the buyer. If the business assumes H1 but the carrier files under H6 or H7, the business may overstate landed cost and create unnecessary checkout friction.

That is why customs-data alignment is now a commercial issue as much as a compliance issue. Businesses should review:

• Their carriers and clearance paths.
• Whether shipments are postal, courier, or standard declarations.
• Whether they offer DDP or DAP checkout experiences.
• How they collect and store HS codes.
• Whether their product catalogue supports accurate grouping.
• How they validate descriptions, country of origin, and declared values.

H1, H6, and H7: Quick comparison
 

The steps below will not eliminate all uncertainty — customs outcomes depend on many factors outside any single business’s control. But they represent the practical groundwork that ecommerce sellers, marketplaces, and logistics teams can put in place now to reduce the risk of mismatches between what is collected at checkout and what is assessed at the border.

1. Confirm their clearance model: Ask your carriers and customs brokers whether they will file H1, H6, or H7 declarations for low-value EU imports.
2. Align calculation assumptions with the actual customs filing path: Confirm that the clearance model used for duty calculation reflects how the carrier, postal operator, or broker will declare the shipment at the border.
3. Review product classification quality: Ensure products are classified with accurate HS, CN, or TARIC codes as needed.
4. Improve product descriptions: Avoid vague descriptions such as “accessories,” “parts,” or “clothing.” Use customs-grade descriptions that support classification and grouping.
5. Validate country-of-origin data: Origin may affect classification treatment, preferential duty claims, and grouping.
6. Review DDP and DAP strategies: Decide whether duties and taxes will be handled upfront or after import. Under DDP (Delivered Duty Paid), the seller or merchant collects and pays import duties and taxes before delivery, creating a more predictable landed-cost experience for the buyer. Under DAP (Delivered at Place), the buyer is responsible for paying duties, taxes, and fees after the shipment arrives, which can create additional delivery friction or surprise charges.
7. Monitor product identifier requirements: New product identifier data can be supplied voluntarily and becomes mandatory from 1 November 2026.

AvaTax Cross-Border helps businesses calculate customs duties and import taxes in real time, supporting product classification, landed-cost estimation, and DDP buyer experiences designed to reduce checkout uncertainty and the risk of under- or overcollection. Critically for the EU reform, it supports all three declaration types — H1, H6, and H7 — allowing sellers, marketplaces, and logistics partners to align their duty calculations with the actual clearance model used by their carrier or broker. As the reform continues to evolve, accurate classification, data readiness, and carrier alignment will only become more important.

Businesses that put the groundwork in place now are better positioned to reduce customs surprises, protect conversion rates, and deliver a more predictable experience for international buyers. Speak with Avalara today about your cross-border challenges.
