Choose Your Preferred Length to Save on Shipping

We offer flexible length options for 6-foot rod, tube, and rollstock materials.
To help you avoid costly carrier surcharges, choose the option that works best for your needs:

  • Standard 6-Foot Length (Oversize)
    Carrier-mandated oversize fee applies due to package dimensions exceeding 48”. This charge is added by UPS/FedEx—not TAP Plastics—and covers manual handling of long items. Only one oversize fee is applied per order.

  • Cut at 3-Foot Lengths (No Oversize Fee)
    We'll cut your item in half at no additional cost to help you avoid the oversize shipping charge. Perfect for smaller projects or convenient handling.

  • Custom Length (Specify in Checkout Comments)
    Need specific sizes? Select “Other (specified in comments).”
    Custom cutting is available—some requests may incur a labor fee. We’ll contact you with details before processing.

ⓘ Why the Fee?
UPS and FedEx charge extra for packages over 48" long—including required padding—for manual handling. These oversize fees apply on top of regular shipping rates, and may also apply to heavy or extra-long packages. TAP applies a flat fee to help cover these added carrier costs.
