Writing an MSDS That Survives a Customs Inspection
Surviving a customs safety inspection requires exact alignment between Section 3 composition, Section 9 physical properties, and Section 14 transport codes.
TSCA Section 13
Meaning
TSCA Section 13 is a United States regulatory provision that requires importers of chemical substances, mixtures, or articles containing chemicals to certify compliance with the Toxic Substances Control Act at the port of entry. This certification must state either that the imported shipment complies with all applicable TSCA rules or that the chemical is not subject to the act. Sourcing and logistics teams must secure these certifications for all imported battery chemicals, such as novel electrolyte salts or active cathode materials, to prevent customs delays.
This regulatory requirement moves procurement decisions by prioritizing suppliers who provide complete chemical composition data to support the import declaration.
Import Rule
The regulation mandates that the importer of record must submit a signed certification to the United States Customs and Border Protection before the goods are released. This certification is divided into a positive certification, which confirms compliance with all TSCA regulations, and a negative certification, which applies to substances excluded from the act. Sourcing specialists must ensure that their customs brokers receive these documents before the cargo arrives at the port of entry.
If the certification is missing or incorrect, customs authorities will detain the shipment, resulting in demurrage charges and supply chain delays. This rule ensures that all imported battery chemicals comply with national safety standards.
Agency Review
The Environmental Protection Agency is responsible for reviewing these certifications and auditing imported chemical shipments to verify compliance with TSCA inventory and reporting requirements. This review process involves checking that all chemical ingredients in the imported battery electrolyte are listed on the TSCA active inventory or are exempt from listing. Sourcing managers must coordinate with their chemical suppliers to obtain the CAS numbers of all components, ensuring that no unregistered chemicals are imported.
This coordination prevents regulatory violations and the potential for severe civil penalties.
Sourcing Delay
Sourcing teams can mitigate the risk of import delays by qualifying suppliers who have already secured TSCA compliance for their chemical products. Sourcing contracts must include warranties that require the supplier to provide all necessary chemical information and compliance documentation to support the import process. This contractual requirement is essential when sourcing specialty chemical additives from foreign suppliers who may not have a registered corporate presence in the United States.
Proactive compliance management under this section ensures the uninterrupted flow of critical chemical raw materials to the battery production facility.
