Essential Mailing Requirements and Regulations
USPS has specific rules for mailing clasp envelopes. These envelopes can be tricky to ship due to size and weight limits9. The USPS mailing regulations clearly define what’s considered an envelope versus a package.
When using clasp envelopes, watch out for size limits. An envelope becomes “large mail” if it’s over 6⅛″ high, 11½″ long, or ¼″ thick9. Anything bigger than 12″ high, 15″ long, or heavier than 13 oz becomes a package.
Clasp envelopes come with a non-machinable surcharge. This extra fee applies even to envelopes weighing less than 1 oz9. Postal workers must handle these envelopes by hand, which explains the added cost.
Make sure your envelope is at least 3½” x 5″ in size. Also, keep it under 13 oz to avoid surprise shipping fees9. Following these guidelines will help you mail your clasp envelopes smoothly.
