Mr Quyen - Santiago. Posted 13/11/2026
A Singapore trading company can buy Santiago ASA/PVC roof tile sheets straight from the factory in Vietnam: one 40 ft container holds about 5,000 m of sheet, colours, profiles and accessories can be mixed, and production takes about 5 days. Each container ships under HS 3925.90.00 with an origin document, so the importer can use CPTPP or the ASEAN Form D (ATIGA) route; your customs broker confirms the rate. Samples are free and the buyer pays the courier.

Why do Singapore traders buy roofing direct from a factory in Vietnam?
Many building-material traders in Singapore keep a small warehouse, or none at all, and sell to contractors at home and to buyers elsewhere in the region. What they need from a roofing supplier is plain: a container that can carry several products in one shipment, a short production time, and papers that customs accepts without questions.
Santiago makes the sheet itself in Vietnam, so the trader deals with the factory that extrudes it, not with a middleman. The tile sheet has four co-extruded layers with no glue: an ASA top layer that holds the colour and blocks UV, a virgin PVC layer, a PVC core and a milky-white PVC base. The material is virgin, not recycled. Santiago has exported to India since 2023, to Thailand since 2024 and to the USA since 2025.

What PVC roofing can a distributor stock?
Most traders start with the Spanish-style tile sheet for houses and add one or two corrugated profiles for sheds, canopies and farm buildings. Everything below can go in the same container.
| Product | Size | Notes |
|---|---|---|
| ASA/PVC roof tile sheet | 1.05 m wide, 0.96 m cover width, tile step 219 mm | Cut to length in 219 mm steps; about 5.4 kg per m² of roof at 2.5 mm |
| Corrugated, 5 waves | 1.08 m wide, 1.00 m cover, wave 32 mm | 2.5 mm sheet about 5.2 kg per running metre |
| Corrugated, 6 waves | 1.06 m wide, 0.95 m cover, wave 34 mm | Same layers as the tile sheet |
| Corrugated, 11 waves | 1.05 m wide, 1.00 m cover, wave 20 mm | Same layers as the tile sheet |
| Skylight sheet | Lets through 80 – 90% of light | Used on 5 – 10% of a roof |
| Accessories | Ridge cap, hip ridge, three-way and four-way pieces, ridge terminal, eave sealing tile, vertical wall flashing, ASA screw caps | Same colours as the sheets |
Thickness is 2.5 or 3.0 mm, and 2.5 mm is the minimum for a roof. The standard colours are dark grey, red, blue, orange and chocolate; green, white and purple are made to order, and so is a dark underside.
How could a first mixed 40 ft container look? A worked example
Take a trader who sells mainly to house builders and some shed contractors. One way to fill the first container of about 5,000 m:
| Line | Running metres | Roof it covers |
|---|---|---|
| Tile sheet, dark grey, 2.5 mm | 1,800 m | 1,800 × 0.96 m = 1,728 m² |
| Tile sheet, red, 2.5 mm | 1,200 m | 1,152 m² |
| Tile sheet, chocolate, 2.5 mm | 800 m | 768 m² |
| Corrugated 5 waves, blue | 700 m | 700 × 1.00 m = 700 m² |
| Corrugated 11 waves, dark grey | 500 m | 500 m² |
| Total sheet | 5,000 m | about 4,850 m² |
| ASA screw caps for the tile sheet | 3,648 m² × 4 – 5 sets per m² | about 14,600 – 18,200 |
| Ridge, hip, terminals, eave sealing tile | Matched to the colours above | Listed line by line in the quotation |
Because the tile sheet is cut to order, a distributor can hold a few lengths that suit common roof faces instead of one fixed size. Every length is a whole number of 219 mm steps, for example 3.066 m (14 steps), 4.161 m (19 steps) or 5.037 m (23 steps). Santiago confirms the final mix, lengths and accessories in a written quotation.
Which origin route: CPTPP or ASEAN Form D?
Singapore and Vietnam are both CPTPP members and both in ASEAN, so a container of Santiago roofing can enter Singapore with a CPTPP proof of origin or an ATIGA Form D, and Santiago provides the origin document for each container. Your customs broker picks the route and confirms the rate. If you want certainty before the first order, ask Singapore Customs for an advance ruling on the classification (HS 3925.90.00) and origin.
Can the sheets be re-exported from Singapore to other markets?
Many Singapore traders work this way, but the answer depends on the customs rules of each destination, not on Singapore alone. Whether the Vietnamese origin document helps a buyer in a third country, and which papers that buyer's customs wants, is a question to settle with your customs broker before you quote that buyer. Do not promise a duty saving you have not checked.
What papers and checks come with each lot?
- A quality certificate (CQ) with every lot
- The factory's ISO 9001:2015 certificate ICI-23087.D
- Quatest test results
- An origin document for each container (CPTPP proof of origin or Form D)
- HS code 3925.90.00 on the shipping papers
Ask for free samples before the first order (you pay the courier). Measure the thickness, check the 219 mm tile step, and look at the colours in daylight next to the walls and paint your customers use. A distributor who has handled the sample answers contractor questions faster than one reading a brochure.

What should a distributor tell contractors about the roof?
The figures come from Santiago tests: the space under the sheet stays 6 – 8 °C cooler than under bare metal sheet, rain noise is about 80% lower, and bending strength is above 1,000 N. There is no metal in the sheet, so nothing rusts. The ASA layer showed no colour change after 2,000 hours of artificial UV, the colour is rated for 30 years, and real roofs last 25 – 30 years. The warranty is 10 years for 2.5 mm and thicker sheet installed as Santiago recommends.
That last condition matters, so pass the fixing rules on with every order: purlins less than 700 mm apart (440 or 660 mm for the tile sheet), the top purlin 15 – 18 cm below the ridge, a slope of 20 – 45%, 6 mm pre-drilled holes, 70 mm screws with ASA caps through the top of the wave over a purlin, 4 – 5 sets per m², never in the valley, and a one-wave side lap. Santiago sends installation videos but does not install.
Be straight with contractors on approvals too. Santiago holds no Singapore BCA certification and publishes no fire or wind rating for this sheet, so the project's architect or engineer decides where it can be used.

Where are the sheets made? A walk through the Santiago factory
Mr Quyen walks through the Santiago factory in Vietnam and explains it in English: roof tiles and ridge pieces in the yard, a green 5-wave sheet coming off the line, a delivery truck, and the warehouses where a container is being loaded.

How is a mixed container loaded?
Mr Quyen explains in English how orange tile sheets slide down a ramp from the stack into the container while workers in Santiago uniforms stack them inside.

What tests can a distributor show customers?
Three quick scenes from Santiago: a ridge piece under a truck wheel, a torch held to blue and red tile sheets in the yard, and strapped bundles of sheets waiting for loading.

CPTPP: lower import duty on roofing sheets made in Vietnam
Vietnam is one of the 12 member countries of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), together with Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and the United Kingdom. Santiago ASA/PVC roofing sheets and accessories are made in Vietnam (HS 3925.90.00), so buyers in these countries can claim the CPTPP preference when they import them.
- Lower or zero import duty. Each member cuts its tariffs on goods of Vietnamese origin under its own CPTPP schedule, and many tariff lines are already at 0%. Your customs broker confirms the rate that applies to HS 3925.90.00 on the day of import.
- Proof of origin with every container. Santiago prepares the CPTPP origin documents for each shipment, so the importer can claim the preferential rate at clearance.
- Advance rulings. Under CPTPP, an importer can ask its customs authority for a written ruling on tariff classification and origin before the goods ship, so the duty is known before the order is confirmed.
- Faster, more predictable clearance. CPTPP members commit to publish their customs rules and, where possible, to release goods within 48 hours of arrival.
- The same preference on every repeat order. As long as the sheets are made in Vietnam and the origin documents are in order, each new container qualifies again.
Duty rates and paperwork change by country and over time: check the current rate and the proof-of-origin form with your customs broker before you order.

Yes. Tile sheet, 5-, 6- and 11-wave corrugated sheet, skylight sheet and accessories in the standard colours can share one container. Santiago lists every line in the quotation.

Can I re-export the sheets from Singapore?
Ask your customs broker first. Whether the origin document supports any preference in a third country depends on that country's rules.
