Frequently Asked Questions
What are the specific customs inspection risks for importing 'Other hydraulic cements' under HTS 2523.90?
Shipments under this code are frequently targeted for inspection to verify correct classification and to ensure the product does not require additional regulation as a hazardous material. Inspectors will often test samples to confirm the cement meets the ASTM C1157 performance specification for 'hydraulic' properties, as misclassification to a non-hydraulic cement is a common error. Proper, legible labeling of the chemical composition and intended use on commercial invoices and packaging is critical to avoid delays.
What are the key additional costs, beyond the product price, when importing hydraulic cements under HTS 252390?
Key additional costs include a Most-Favored-Nation (MFN) import duty, which for HTS 252390 is currently duty-free for the U.S., and mandatory Merchandise Processing Fees (MPF) assessed by U.S. Customs at 0.3464% of the entered value (minimum $27.23, maximum $614.35). You must also factor in Harbor Maintenance Fees (HMF) of 0.125% on the cargo value if arriving by vessel, plus applicable customs bond costs.
Specialty Cements: Key Compliance Notes
Imports of specialty cements under 2523.90 often require supporting documentation to verify their specific, non-Portland composition to avoid classification challenges. Certain cement types, such as those containing refractory materials or specific chemical additives, may be subject to additional testing requirements by authorities like the EPA or OSHA for hazardous material content. For imports into the U.S., ensure the supplier provides a detailed Material Safety Data Sheet (MSDS) and a precise chemical breakdown. Shipments may also require specific packaging and labeling if classified as hazardous or if they contain substances regulated by the Toxic Substances Control Act (TSCA).
