Amazon TIC Power Bank UL2743 & UN38.3 Certification

For sellers of portable power supplies looking to establish a presence on Amazon US and Canada, the platform’s compliance policy adjustments from late 2025 to early 2026 mark a critical turning point. Amazon has officially classified portable power supplies (including functional products such as jump starters) into the scope of Third-Party Testing, Inspection, and Certification (TIC) audits. It explicitly mandates that all relevant products must obtain dual certifications of UL2743 and un38.3, with compliance verification completed by designated TIC service providers and reports directly submitted to the platform.

This reform not only overhauls the previous compliance process but also directly determines whether products can remain listed for sale, becoming a "life-or-death threshold" that sellers must cross.

Core Policy Changes: TIC Audits Reshape Compliance Logic

The core shift in Amazon’s compliance policy lies in the complete abandonment of the old model where sellers independently submitted testing documents, replacing it with a full-scale implementation of the Direct Verification (DV) system.

This means sellers can no longer upload test reports on their own. Instead, they must collaborate with Amazon-approved third-party TIC service providers, who will either conduct product testing or verify the authenticity and validity of existing documents. Finally, compliant reports are encrypted and directly uploaded to Amazon’s backend system.

Amazon’s primary objective with this measure is to eliminate fraudulent reports, strengthen product safety controls, and safeguard consumer rights from the source. According to the platform announcement, the policy officially took effect on December 10, 2025, and a centralized delisting process for non-compliant products will be initiated on March 10, 2026.

Whether for newly listed ASINs or existing inventory, all products subject to platform random inspections or compliance verification notices must strictly follow this process. Failure to do so will result in risks such as Listing delisting and account restrictions.

It is important to clarify that Amazon explicitly categorizes portable car jump starters under the scope of portable power banks, making them subject to the mandatory UL2743 + un38.3 certification requirements. They are not treated as a special category exempt from the policy.

These multi-functional products integrating jump starting, lighting, and charging capabilities, due to their higher power output and more complex application scenarios, have become key targets of the platform’s compliance supervision.

Dual Certification Analysis: Core Requirements of UL2743 and UN38.3

In Amazon’s mandatory certification requirements for portable power supplies, UL2743 and UN38.3 respectively focus on product usage safety and transportation safety. Both are indispensable, jointly forming the "dual passports" for products to enter the market.

(I) UL2743: Core Benchmark for Portable Power Supply Usage Safety

UL2743 is a dedicated safety standard for portable power banks, with the full title ANSI/CAN/ul 2743, Standard for Safety for Portable Power Banks. The latest revised version officially came into effect on October 4, 2025, and outdated reports not updated in a timely manner will be revoked.

This standard sets stringent testing requirements for portable power supplies (including jump starters) in terms of electrical safety, mechanical safety, and environmental adaptability, covering safety risks throughout the entire product lifecycle.

Its core testing items fall into three categories:

1. Electrical Safety Testing: Includes power input testing, lithium battery charging system verification, leakage current testing, dielectric withstand voltage testing, overload and short-circuit protection testing, etc. These ensure the product’s electrical circuit design complies with standards and prevents risks such as electric leakage and overheating.

2. Mechanical Safety Testing: Encompasses casing strength testing, handle strength testing, stress relief testing, stability testing, etc. These are tailored to scenarios involving collisions and bumps during outdoor carrying and movement.

3. Environmental and Special Function Testing: Involves rain resistance testing, high and low-temperature environmental simulation, jump starter function verification, etc. Particularly for the special usage scenarios of jump starters, it enhances requirements for performance stability under extreme conditions.

Notably, the UL2743 standard explicitly applies to portable/movable power banks weighing under 18kg or equipped with wheels, covering various battery types such as lead-acid and lithium-ion batteries. It also requires that integrated additional functions (e.g., jump starting, LED lighting) must be tested as a whole and cannot be evaluated separately. For products with large-capacity energy storage systems, the standard has added specific requirements, further raising the safety threshold.

(II) UN38.3: Internationally Recognized Guideline for Lithium Battery Transportation Safety

UN38.3 is a mandatory safety standard for lithium battery transportation specified in the United Nations Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria. Its core objective is to ensure that the lithium batteries built into portable power supplies can withstand various extreme environments during cross-border transportation (especially air transportation) without safety incidents such as fire, explosion, or leakage.

For portable power supplies entering the North American market via air freight, UN38.3 certification is an indispensable transportation approval document.

The standard includes 8 core testing items, fully simulating extreme conditions during transportation:

• Altitude simulation (low-pressure environment)

• Thermal testing (high and low-temperature shock)

• Vibration testing

• Shock testing

• External short-circuit testing

• Impact/crush testing

• Overcharge testing

• Forced discharge testing

The key criteria for passing the tests are that the battery must not disintegrate or catch fire during testing, and any leakage must not be toxic, flammable, or corrosive.

Amazon explicitly requires sellers to provide both a un38.3 test report and a BTS (Battery Test Summary) document to prove that the product fully meets transportation safety requirements. Like the UL2743 report, these two documents must be issued by the ISO 17025-accredited JJR Laboratory, with the report date within the past 12 months; otherwise, they will be deemed invalid.

Compliance Operation Process: A Step-by-Step Guide from Preparation to Audit

Faced with the new TIC audit process, sellers should follow the logic of Self-inspection → Testing → Verification → Audit to advance compliance work in an orderly manner, avoiding delays caused by procedural oversights. The specific steps are as follows:

Step 1: Self-inspect Product Information and Qualification Status

First, log in to the Amazon Seller Central, navigate to the Performance → Account Health → Policy Compliance section, and confirm whether all ASINs of portable power supplies (including jump starters) in the store have received compliance notices.

Second, review product detail page information to ensure that the model number, part number, and manufacturer/brand name are fully indicated. Product images should clearly display labels, compliance marks, and hazard warnings. For sellers on the Canadian site, ensure that manuals, warning labels, and other materials are provided in both English and French.

Meanwhile, sort out existing qualification documents and verify whether valid UL2743 and un38.3 test reports are available. Focus on checking if the issuing laboratory holds ISO 17025 accreditation and if the report date is within the 12-month validity period. If the report is based on the old version of the UL2743 standard (prior to October 4, 2025), initiate the update process immediately.

Step 2: Connect with Designated TIC Service Providers and Submit Samples for Testing

For products without valid certifications or with expired reports, promptly contact Amazon-approved third-party TIC service providers. Through the "Verify Your Products" portal in Seller Central, select a service provider and generate a TRF (Test Request Form) number, which is a key credential for subsequent report submission.

Prepare samples for testing (usually 2–3 mass-produced samples) and relevant technical documents as required by the service provider, including product specifications, circuit diagrams, and bill of materials (BOM). Clearly inform the service provider of the product type (including jump start function) to ensure that testing items fully cover all requirements of UL2743 and UN38.3.

The testing cycle at JJR Laboratory typically ranges from 5 to 15 working days, depending on product complexity.

Step 3: Complete TIC Verification and Direct Report Submission

After completing the testing, the TIC service provider will conduct a secondary verification of the report’s authenticity and validity, confirming the consistency between the product and the test report, label compliance, and manual completeness.

Upon successful verification, the service provider will submit the encrypted test report directly to Amazon’s backend system—no action is required from the seller. During this process, sellers must promptly respond to the service provider’s requests for supplementary materials to ensure the smooth progress of the verification process.

Step 4: Track Audit Results and Maintain Ongoing Compliance

After receiving the report submitted by the TIC service provider, Amazon will conduct a final audit. ASINs that pass the audit will resume normal sales status, and sellers will receive a confirmation notice from the platform.

If the audit fails, sellers must collaborate with the service provider to address the issues identified by the platform (e.g., incomplete report information, inconsistencies between the product and the report) and resubmit the application.

It should be noted that Amazon will conduct regular random inspections or unscheduled additional evaluations of products. Therefore, sellers must establish a long-term compliance mechanism, properly store test reports, certification certificates, and other documents. In the event of product design changes, timely retesting and qualification updates are required.

Urgent Action Recommendations: Key Measures to Avoid Delisting Risks

With the March 10, 2026 centralized delisting deadline fast approaching, sellers must prioritize tasks and expedite compliance efforts:

1. Prioritize ASINs that have received compliance notices: These products have been flagged by the platform for key inspection, and delays may result in immediate delisting.

2. Proactively update certifications for core ASINs with large inventory: Even if no notice has been received yet, completing certification updates in advance can prevent penalties due to non-compliance during random inspections.

3. Select experienced TIC service providers with testing capabilities for the latest UL2743 standard: This can shorten testing and verification cycles while ensuring report recognition by the platform.

4. Prioritize UL-certified models for key components (e.g., batteries): This reduces the risk of test failures and improves certification efficiency.

Amazon’s strengthened compliance requirements for portable power supplies essentially reflect the platform’s enhanced commitment to consumer safety, and are an inevitable trend toward the standardized development of the industry. For sellers, UL2743 + UN38.3 certification is not only a "ticket" to enter the North American market but also the foundation for building brand trust and achieving long-term operations.

In the face of policy changes, proactive planning is far better than passive response. Completing complianCE certifications as soon as possible not only avoids delisting risks but also establishes a compliance advantage in the fiercely competitive market to win consumer favor.

Looking ahead, as global safety standards continue to evolve, staying abreast of policy updates and building a solid compliance defense will become the core competitiveness for portable power supply sellers expanding their overseas businesses.
