About Stackry Shipping
Stackry operates as a package forwarding service with a notable advantage—their US address is in New Hampshire, a state with no sales tax, potentially saving international buyers on qualifying purchases from retailers that calculate tax based on shipping destination. Understanding how Stackry calculates shipping costs helps international customers budget effectively when buying from American retailers and planning their forwarding strategy. Stackry uses the chargeable weight method for shipping calculations, comparing actual weight against volumetric weight and billing based on the higher value—standard practice in the package forwarding industry. They offer shipping through major carriers like DHL and FedEx, plus USPS options, each with distinct dimensional weight policies and pricing tiers that vary by destination country. For international shoppers purchasing US products—whether electronics, fashion, sporting goods, or specialty items—package dimensions significantly impact shipping costs and often determine the final price more than actual weight. Stackry's consolidation and repackaging services can substantially reduce volumetric weight by combining packages and removing bulky retail packaging, helping optimize your overall shipping expenses.
How Stackry Calculates Shipping Costs
Stackry calculates shipping based on chargeable weight—the greater of actual or volumetric weight. Volumetric weight is derived from package dimensions divided by carrier-specific factors. Shipping costs include first weight charges and additional weight increments. Stackry offers both free and premium membership options with different service levels and pricing. Their shipping calculator provides estimates after warehouse measurement.
Volumetric Weight Rules
Stackry applies volumetric weight using standard carrier divisors. DHL and FedEx use 139 (imperial: cubic inches per pound). USPS Priority Mail International uses 166. For a 14" × 10" × 8" package (1,120 cubic inches), volumetric weight is approximately 8.1 lbs with a 139 divisor or 6.7 lbs with a 166 divisor. Stackry's system calculates both weights and shows which applies. Some economy services may have different volumetric thresholds or exemptions for smaller packages.

Frequently Asked Questions
How does Stackry calculate shipping costs?
Stackry uses chargeable weight—the higher of actual or volumetric weight. Volumetric weight = (L × W × H in inches) ÷ divisor (typically 139 or 166 depending on carrier). Costs include first weight plus additional weight increments.
What's the benefit of Stackry's New Hampshire address?
New Hampshire has no state sales tax. For qualifying purchases from retailers that calculate tax based on shipping address, this can mean meaningful savings. Check individual retailer policies as tax calculations vary.
How does Stackry consolidation work?
When packages arrive at your Stackry address, you can request consolidation. Their warehouse combines items into a single shipment, removing unnecessary packaging. This typically reduces total volumetric weight and shipping costs.
What volumetric divisor does Stackry use?
Stackry applies carrier-standard divisors: DHL and FedEx use 139, USPS uses 166. The higher divisor (166) results in lower volumetric weight for the same package size. Compare carriers in your account for specific rates.
Can I reduce my Stackry shipping costs?
Yes—consolidate packages, request repackaging, choose carriers with favorable volumetric rates, use economy options for non-urgent shipments, and time purchases to maximize consolidation efficiency.
Is Stackry's free membership sufficient?
The free tier provides basic forwarding services. Premium membership offers benefits like longer storage, discounted rates, and priority handling. Evaluate based on your shipping volume and whether the perks justify the cost.
Which carrier is cheapest on Stackry?
The cheapest option depends on package size, weight, and destination. USPS often offers better volumetric rates due to the higher divisor. Economy services cost less but take longer. Compare all options in your Stackry dashboard.
How long can I store packages at Stackry?
Free accounts typically have limited storage periods. Premium membership extends storage time. Check current terms in your account. Plan consolidation timing to avoid storage fees while collecting enough packages for efficient shipping.
