U.S. imports of Molds for Rubber or Plastics (Other Than Injection or Compression Types) (HS 848079) totaled $20.0M in September 2026, imported from 50 countries.
Importers of Molds for Rubber or Plastics (Other Than Injection or Compression Types) paid $3.5M in duties in September 2026, an average duty rate of 17.64% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Molds for Rubber or Plastics (Other Than Injection or Compression Types) imports of $20.0M in September 2026 ran 15% below the year-to-date monthly average of $23.6M.
Last updated: September 2026 dataBlow molds, bladder-operated molds, and other non-injection, non-compression tooling for rubber and plastics serve distinct forming processes — blow molding for hollow containers and bladder curing for tires and industrial rubber goods — and each carries its own classification under this heading. The five 10-digit lines include dedicated provisions for shoe machinery molds (8480791000), blow molds (8480799010), bladder-operated molds (8480799020), and a residual NESOI line (8480799090). Canada and Germany are the leading sources of US imports under this heading, with China also a significant supplier. As with injection molds, goods of Chinese origin may be subject to Section 301 tariffs, and the process-specific nature of these tools means misclassification between blow and bladder lines is a recurring audit risk.

A bladder-operated mold (8480799020) uses an internal inflatable bladder to apply forming pressure — most commonly in tire vulcanization — whereas a compression mold (classified under heading 848071) applies external mechanical pressure to shape the material. The forming mechanism, not the material being molded, drives the classification distinction.
Generally, a single article is classified as a whole under the line that best describes its primary function. If the mold is purpose-built for blow molding, 8480799010 applies; if compression is the primary function, it falls under heading 848071. Importers with combination tooling should seek a CBP binding ruling to avoid post-entry reclassification.
