Customs-figure tool · Information, not advice
Is your box within the volume cap?
A balikbayan box is defined as a container up to a maximum volume of 200,000 gross cubic centimetres, without regard to shape — CAO 01-2018 §3.2. Enter your length, width and height in inches or centimetres and this shows the gross cm³ against that figure, with the exact headroom or overage. It runs in your browser; nothing you type is sent or stored. Size (§3.2) is a different limit from value (§4.2) and from the couriers' own weight tiers — the tool keeps the three apart.
Three separate limits — this tool checks only the first
- Size
A balikbayan box is defined as a container up to a maximum volume of 200,000 gross cubic centimetres, without regard to shape. That is the figure this tool applies to your dimensions. CAO 01-2018 §3.2
- Value
A separate ceiling: ₱150,000 total FCA value of all boxes per sender per calendar year (CAO §4.2). It is not the same as size and is not computed here. The ₱150,000 value limit
- Weight
Couriers set their own weight tiers. No customs weight cap exists in the CAO — so this tool does not check weight, and there is no customs weight figure to read into it. Courier weight & size tiers

Against the 200,000 gross cm³ volume the balikbayan-box definition sets in CAO 01-2018 §3.2 . This is what §3.2 defines, applied to your numbers — not advice.

Volumes are arithmetic on each courier's posted inch dimensions (edge × 2.54 = cm; L × W × H). 4 of the 10 posted tiers above measure more than the 200,000 cm³ §3.2 figure. That is a size-to-definition comparison, not a customs determination on any shipment — confirm with the courier. The same rows are in box-tier-dimensions.csv; the §3.2 figure is in customs-constants.csv.

A worked example
Take the Extra Large tier LBC posted on its US sea-freight page (since removed; Internet Archive capture of 2026-10-12), 24 × 18 × 24 inches, and apply the §3.2 figure step by step:
- Multiply the three edges 24 × 18 × 24 = 10,368 cubic inches
- Convert to centimetres 1 inch = 2.54 cm, so cubic inches × 2.54³ (16.387064) → 10,368 × 16.387064 = 169,901 gross cm³
- Compare to the §3.2 cap 169,901 cm³ vs the 200,000 cm³ maximum = 30,099 cm³ under it (about 85% of the cap)
In centimetres directly the box is 60.96 × 45.72 × 60.96 cm, which multiplies to the same 169,901 gross cm³ — the unit toggle above just does this conversion for you. Not every posted tier lands under the figure: Highlight Express's Ultra Jumbo, 38 × 26 × 26 inches, works out to 420,951 gross cm³, about 2.1× the 200,000 cm³ that CAO 01-2018 §3.2 uses to define a balikbayan box.
