At UMETASS, our 5LF (5L), 10LF (10L) and 20LF (20L) square plastic buckets have passed the UN packaging drop tests recorded under SN/T 0370.2-2021. Testing took place from 14 to 16 October 2026. All three models received a Pass result after the samples and simulant were frozen to −18°C and subjected to a 1.2-metre drop test.
For buyers evaluating square plastic pails, these results provide a specific basis for assessing packaging performance: identified models, documented test conditions and UN packaging marks visible on the corresponding samples. Here, we explain what was tested, how to read the markings and how to select the appropriate LF configuration for your project.
Our tested LF models cover three nominal capacities within the square bucket range. Each has its own marked maximum gross mass, allowing purchasing and technical teams to compare the options on a consistent basis.
Model | Nominal capacity | Marked maximum gross mass | UN packaging mark |
|---|---|---|---|
5LF | 5 L | 6 kg | 3H2/Y6/S/26 |
10LF | 10 L | 12 kg | 3H2/Y12/S/26 |
20LF | 20 L | 24 kg | 3H2/Y24/S/26 |
Maximum gross mass includes the contents and the complete packaging assembly. It must not be read as the permitted net product weight. The full marks above reproduce the 2026 samples; production-date elements must correspond to the actual packaging supplied.
The reports identify the products as open-top plastic cans or pails and record the following conditions for all three sizes.
Test detail | Recorded information |
|---|---|
Test standard | SN/T 0370.2-2021 |
Test dates | 14–16 October 2026 |
Sample quantity recorded | 9 per model |
Test item | Drop test |
Drop height | 1.2 m |
Preconditioning | Samples and simulant frozen to −18°C |
Impact positions recorded | Top embossed sealing edge and seam line |
Simulant | Similar solids |
Recorded result | Pass for all three models |
The sample numbers are 202600251 for 5LF, 202600252 for 10LF and 202600253 for 20LF. These references help connect each set of results to the correct model during a technical review.
A drop test evaluates how a filled package responds to impact under defined conditions. In these tests, impact positions included the upper sealing edge and seam line, making the results relevant to the interaction between the container body and closure. The cold preconditioning adds a clearly documented condition to that assessment; it is not a general storage-temperature rating.
For example, our 10LF sample carries the mark 3H2/Y12/S/26 CN/C331116. Its elements identify the packaging type and marked performance parameters.
Element | Meaning |
|---|---|
3H2 | A removable-head plastic jerrican classification in the UN packaging coding system. We market the product as a square bucket or pail. |
Y | The performance level associated with Packing Groups II and III. |
12 | Maximum gross mass of 12 kg for the marked 10LF packaging. |
S | Packaging for solids or inner packagings; these reports record a similar-solid simulant. |
26 | The year-of-manufacture element shown on these 2026 samples. |
CN | China, the country element of the mark. |
C331116 | The company identification code recorded in the reports and sample markings. |
The Y marking is a performance-level designation, not an authorization for every substance in those packing groups. Product classification, chemical compatibility, packing instructions, closure requirements and transport conditions still determine whether a particular configuration is suitable. These S-marked results should not be presented as proof for directly filling and transporting hazardous liquids.
We want buyers to be able to verify the product they are evaluating. The report for each LF size identifies the sample, test standard, conditions and result. The corresponding sample photograph shows its UN packaging mark. Together, these records support a more precise technical discussion than a general statement about durability.
For procurement teams, that means three useful checks: confirm the model and closure configuration; compare the planned filled gross mass with the marked limit; and review the evidence against the intended contents. The 5L, 10L and 20L capacities provide practical size options, while their separate markings keep the performance information model-specific.
Our LF range uses a square format with a wide opening and removable lid. This layout can help organize packing space and provide access for filling or removing solid products. The actual pack-out, pallet arrangement and filled handling requirements should be agreed for the selected size and application.
At UMETASS, our manufacturing support covers injection-moulded packaging, tooling, decoration and export packing. Our quality workflow includes material and component verification, first-article approval, in-process inspection and checks on dimensions, appearance and the agreed product characteristics.
For an LF project that requires UN-marked packaging, we start with the intended contents and the configuration required. We then review the relevant test records, container and lid specification, marking and packing requirements together. Any requested change to the material, closure or product structure needs to be checked against the applicable documented scope.
Which LF square bucket sizes have passed the reported tests?
Our 5LF, 10LF and 20LF models, corresponding to nominal capacities of 5L, 10L and 20L, all received a Pass result in the reported drop tests.
What were the main test conditions?
The reports record a 1.2-metre drop after the samples and similar-solid simulant were frozen to −18°C. Testing followed SN/T 0370.2-2021 on 14–16 October 2026.
Does Y24 mean that the 20LF bucket can carry 24 kg of product?
No. The 24 kg designation is maximum gross mass. The contents, bucket, lid and other packaging components must be included when checking the completed package weight.
Can I specify a different lid or custom material?
Share the proposed configuration with us. We will review it against the relevant product specification and test scope before confirming the packaging solution.
How can I review the documentation for my project?
Contact us with the LF size, intended contents, target fill weight, destination and transport mode. If the contents are dangerous goods, include the SDS and the known UN number and packing group so that the technical review addresses the actual application.
If you are comparing square plastic buckets with documented UN drop-test performance, our 5LF, 10LF and 20LF models provide three clearly identified options. Tell us what you need to pack, your target fill weight and order quantity. We can review the relevant documentation and help you define the next steps for samples and quotation.
