Last updated: June 2026 dataRubber sealing components — O-rings, oil seals, and gaskets — are critical inputs for automotive, aerospace, and industrial fluid-handling systems, and this heading carries one of the most granular US tariff structures in Chapter 40. The schedule separates automotive-use articles (Chapter 87 goods: 4016931010, 4016931020, 4016931050) from non-automotive equivalents (4016935010, 4016935020, 4016935050), with O-rings and oil seals each receiving their own lines. Mexico is the leading supplier, reflecting deep automotive-sector integration, followed by Japan and China. Goods from Mexico may qualify for preferential treatment under USMCA where applicable rules of origin are met.

CBP distinguishes automotive-use seals (destined for vehicles of Chapter 87) from general-purpose seals based on the article's design specifications and the buyer's intended application. A technical drawing, purchase order referencing a vehicle OEM part number, or supplier's product data sheet identifying the article as an automotive component all serve as supporting documentation. Misclassification between the automotive and non-automotive lines can affect duty rates, so maintaining clear end-use records is important.
O-rings used in aircraft or hydraulic systems are not Chapter 87 automotive goods, so they fall under the non-automotive O-ring line (4016935010) rather than the automotive line (4016931010). Aerospace O-rings often carry AS9100 or MIL-spec certifications that affect buyer qualification requirements but do not alter the HTS classification itself.
