Products classified under HTS 4001.21.00.30
Grade 3 Smoked Rubber Sheets
These are natural rubber sheets produced from latex coagulated into sheets, then smoked over wood fires to preserve and darken them, specifically meeting Grade 3 quality standards with moderate impurities and discoloration. Classified under HTS 4001.21.00.30 as smoked sheets of natural rubber in primary forms, they serve as a raw material for further processing into tires, seals, and footwear. The smoking process imparts elasticity and durability typical of natural rubber.
Ribbed Smoked Sheets Grade 3 (RSS3)
Ribbed Smoked Sheets (RSS3) are standard Grade 3 natural rubber sheets with visible ribbing from the coagulation process, smoked for preservation, containing allowable levels of dirt and moisture. This product fits HTS 4001.21.00.30 due to its smoked sheet form in primary shapes, used primarily in tire production and rubber compounding. The ribbed texture aids in uniform drying and quality grading.
Standard Indonesian Smoked Rubber Sheets Grade 3
Produced in Indonesia from Hevea brasiliensis latex, these Grade 3 smoked sheets have a dark brown color from smoking, with permissible specks and slight porosity. They are imported in primary sheet form under HTS 4001.21.00.30 for use in conveyor belts and automotive parts. This classification reflects their uncompounded, primary state without vulcanizing agents.
Thai RSS3 Smoked Rubber Sheets
Thailand-sourced Ribbed Smoked Sheets Grade 3 (RSS3) are natural rubber in thin, ribbed sheets smoked to achieve pliability and resistance to decay, meeting Grade 3 specs for cleanliness. Under HTS 4001.21.00.30 as primary smoked sheets, they are ideal for molding into seals and gaskets. No additives beyond permitted emulsifiers preserve their raw material status.
Vietnamese Grade 3 Smoked Natural Rubber Sheets
Grade 3 smoked sheets from Vietnam feature a pliable texture from controlled smoking, with allowable discoloration and foreign matter per SIRIM standards. Classified in HTS 4001.21.00.30 for their primary sheet form, used in vibration dampeners and hoses. They retain essential natural rubber character without prohibited compounding.
Grade 3 Pale Crepe Equivalent Smoked Sheets
These smoked sheets approximate pale crepe quality at Grade 3 level, with low odor and consistent thickness for blending in rubber mixes. HTS 4001.21.00.30 covers them as smoked natural rubber sheets in primary form, destined for medical tubing and adhesives. Smoking differentiates them from air-dried crepe.
Bulk Grade 3 Smoked Rubber for Tire Manufacturing
