Customs warehouse in Poland: EU rules, time limits and responsibilities
Customs warehousing allows non-Union goods to be stored under customs supervision without import duty while they remain under that procedure. It is a distinct customs procedure. Temporary storage and transit serve different purposes and have different conditions.
The legal foundation is the Union Customs Code (UCC), Regulation (EU) No 952/2013, particularly UCC Art. 237 and UCC Art. 240. This guide concerns EU customs law and its application in Poland.
Three services with different legal functions
A warehouse is a physical location. A customs procedure determines the legal treatment of the goods. The building alone cannot tell you which operations are permitted or who is responsible. The UCC lists transit and customs warehousing in separate categories of special procedures and defines temporary storage separately. UCC Art. 5 UCC Art. 210
| Mechanism | Purpose | Time and handling | Legal basis |
|---|---|---|---|
| Temporary storage czasowe składowanie | The situation of non-Union goods between presentation to customs and placement under a customs procedure or re-export. It is not itself a customs procedure. | Goods must be placed under a procedure or re-exported within 90 days. Handling is limited to preserving them in an unaltered state without changing their appearance or technical characteristics. | UCC Art. 5 (17), UCC Art. 144, UCC Art. 147 (2), UCC Art. 149 |
| Customs warehousing składowanie celne | Storage under a special procedure in premises or locations authorised by customs and under customs supervision. | No general storage time limit; customs may impose one in exceptional cases involving health or environmental risks. Usual forms of handling are possible within the applicable rules. | UCC Art. 220, UCC Art. 237, UCC Art. 238, UCC Art. 240 |
| External Union transit, generally T1 tranzyt | Movement, generally of non-Union goods, between points within the EU customs territory with suspension of the relevant charges. | Goods and required information must be presented at destination within the prescribed time, observing identification measures. Transit authorises movement, not long-term warehousing. | UCC Art. 226, UCC Art. 233 |
The European Commission provides separate explanations of temporary storage on importation and customs warehousing. These assist interpretation; the relevant operator's authorisation sets conditions for the particular facility.
Customs status is not the seller's country
“Goods from Ukraine” and “non-Union goods” are not equivalent descriptions. Origin and customs status answer different questions. Goods of foreign origin can acquire Union status following release for free circulation. Establish the current status and previous customs treatment rather than relying only on the seller's address on an invoice. UCC Art. 5 (22–23), UCC Art. 201 (3)
Customs may permit Union goods to be stored in a customs warehouse where the stipulated conditions are met. Their presence in that building does not place them under the customs warehousing procedure. Likewise, processing or end-use activities inside the facility can take place under a different procedure. UCC Art. 237 (3), UCC Art. 241
What does “no general time limit” mean?
The UCC does not impose a general 90-day limit on customs warehousing. That does not create an unlimited commercial storage contract: charges, contractual terms, authorisation conditions and product-specific requirements still matter. The Code permits customs to set a deadline in exceptional circumstances where prolonged storage threatens human, animal or plant health or the environment. UCC Art. 238
The 90-day rule belongs to temporary storage. Moving pallets to another area or issuing a new transport document does not by itself convert temporary storage into customs warehousing. The appropriate customs treatment and the conditions of the selected procedure must be satisfied. UCC Art. 147, UCC Art. 149, UCC Art. 240
Sorting, repacking and processing are not the same
Under customs warehousing, the UCC allows usual forms of handling intended to preserve goods, improve their appearance or marketable quality, or prepare them for distribution or resale. This is not a general permission for any manufacturing process. UCC Art. 220
Assess the actual operation against the applicable rules and authorisation. Poland's Ministry of Finance discusses usual forms of handling and refers to Annex 71-03 of Delegated Regulation (EU) 2015/2446: customs warehousing guidance, July 2025, section 10.3. An operation's label, such as “sorting” or “repacking”, does not establish its eligibility; its substance and consequences matter.
Temporary storage has narrower handling limits: preservation in an unaltered state without changes to appearance or technical characteristics. An operation permitted under customs warehousing cannot automatically be carried out during temporary storage. UCC Art. 147 (2)
Where processing is needed, customs may permit inward processing inside a warehouse facility under the prescribed conditions. During that activity the goods are under the relevant processing procedure, rather than customs warehousing. UCC Art. 241
Suspended duty does not mean “no taxes in every case”
UCC Art. 237 sets out treatment under the storage procedure without import duty and other charges subject to the relevant rules. It is not a universal exemption from VAT, excise or every other obligation for every transaction. The tax outcome depends on the subsequent customs treatment and applicable tax legislation.
For non-Union goods released for free circulation on the EU market, UCC Art. 201 provides for collection of import duty due, other charges as appropriate, completion of formalities and applicable commercial policy measures. A different subsequent treatment can produce a different result. Relevant prohibitions and restrictions do not disappear merely because goods enter a warehouse. UCC Art. 237
The procedure is discharged through a route recognised by the Code, such as placing the goods under a subsequent procedure or taking them out of the customs territory. Selling goods is not, by itself, a universal method of discharging customs warehousing. UCC Art. 215 (1)
Authorisation, records and responsibility
Operating a customs warehouse facility requires an authorisation unless customs itself is the operator. Its conditions define the permitted activity. A user of a public warehouse is a different role from the holder of the facility's operating authorisation: each customer does not become the operator simply by storing goods there. UCC Art. 211 (1(b)), UCC Art. 240 (2)
A public warehouse is available for use by any person; a private warehouse is for storage by the holder of the authorisation. UCC Art. 242 allocates responsibility for customs supervision and storage obligations. In a public warehouse, the authorisation may place some obligations exclusively on the holder of the procedure. A brokerage contract does not justify assuming that all statutory obligations automatically transfer to the broker.
Temporary storage has its own authorisation, guarantee and approved record-keeping requirements. Transit separately imposes duties on the holder of the procedure and on a carrier or recipient who knows the goods are moving under transit. UCC Art. 148, UCC Art. 233
AGL DIVISION AEO status
AGL DIVISION SPÓŁKA Z OGRANICZONĄ ODPOWIEDZIALNOŚCIĄ is listed in the European Commission’s official register as an AEOC holder: authorised economic operator for customs simplifications. Effective date: 7 December 2009. The entry was checked on 16 September 2026; the register’s last import date was 16 September 2026.
This category is governed by Article 38(2)(a) of the Union Customs Code. Paragraph 5 makes a specific simplification subject to its applicable requirements; paragraph 6 provides more favourable treatment for customs controls according to the authorisation type. UCC / UKC / UZK — 38
Connecting warehousing and transit in Poland
Delivery to a warehouse under T1 and placement under customs warehousing are separate legal events. Transit ends when the goods and required information are properly available to customs at destination. Discharge by customs following comparison of departure and destination data is a separate control step. Arrival of the truck does not, on its own, establish both. UCC Art. 233 (2), UCC Art. 215 (2)
PUESC separately describes special procedures, transit formalities and ending temporary storage. A temporary-storage completion message does not replace the declaration for a subsequent procedure. Registration, representation permissions and filing methods depend on the service used.
For movements involving countries outside the EU, assess separately whether common transit under the Convention of 20 May 1987 applies. Union transit rules alone do not explain every international route. See the Commission's explanation of Union and common transit.
Example: a machine awaiting a buyer
A non-Union machine has entered the EU, but its buyer and onward delivery date are uncertain. Temporary storage can bridge the period before a procedure is selected, but its 90-day limit remains binding. If further storage is needed, assess customs warehousing: do the goods, facility and intended handling meet the relevant conditions?
If the machine moves to another place of customs treatment, select a lawful movement arrangement separately; external transit may be suitable where its conditions are met. For subsequent supply onto the EU market, assess release for free circulation and the payments due. Processing requires a separate assessment. One shipment can therefore require several services in sequence without making those services interchangeable.
Questions to resolve before dispatch
- What is the current customs status and what customs treatment has already occurred?
- Is the need for temporary storage, warehousing, movement or processing?
- Which facility will receive the goods, and what goods and operations does its authorisation cover?
- Who will be the holder of the procedure, operator, carrier and representative?
- What deadlines apply to presentation, storage and subsequent treatment?
- What information establishes identity, quantity, value and technical characteristics, and what product restrictions apply?
- Who will confirm the end of transit and placement under the subsequent procedure?
The invoice, packing information, goods description, route and previous customs records help prepare a shipment-specific assessment. These are starting inputs, not a universal exhaustive document list for every kind of goods.
